5+7-2x
12-2x
Which equation represents the line through (4, 5) and (0, –3)?
Answer:
y = 2x-3
Step-by-step explanation:
Y=mx+c
We find m first so
m=y2-y1/x2-x1
= -3-5/0-4
= 2
So y=2x+c
Now we find c, so we sub any of points in the line equation!
Sub (4,5) in y=2x+c
5=2(4)+c
-8+5=c
-3=c
So the answer is D !

I WILL GIVE BRAINLEST HELP ASAP Solve negative a minus six sevenths equals two thirds for a.
a equals negative 32 over 21
a equals 32 over 21
a equals negative 8 over 21
a equals 8 over 21
a equals negative 37 over 24
Step-by-step explanation:
-a-(7/8)=2/3
Add 7/8 to 2/3.
Multiply the numerator and denominator of each fraction by the other's denominator. This keeps the same value for each fraction but makes them easier to add because they have the same denominator.
(7*3)/(8*3)+(2*8)/(3*8)
(21/24)+(16/24)
Add the fractions (add the numerators and keep the denominator).
(21/24)+(16/24)=37/24 or 1 13/24
-a=37/24
Divide 37/24 by -1.
a=-37/24Answer:

What is the measure of an interior angle of a regular decagon?
18°
144°
180°
36°
Answer: 180
Step-by-step explanation:
Answer:
Step-by-step explanation:
A decagon has 10 sides so its interior angles add up to 180(10) - 360 = 1440 degrees. Therefore, on average, each interior angle is 144 degrees and each exterior angle is 36 degrees. The sum of the exterior angles is 10 x 36 = 360 degrees.

Answer:
1. Skylar may have noticed that once you distribute the number outside the parentheses to those within you get a 15x which combines with the 4x thats already on that side to make 19x. Since we have 19x on both sides, whatever else we do is moot because you can't take 19x from 19x without completing getting rid of the variable.

Step-by-step explanation:
You are part of a railroad crew that is connecting empty boxcars to a locomotive. You hitch 13 boxcars before lunch and 6 more after lunch. The total weight of covered wagons is 627 tons. Write and solve an equation to find the weight of each boxcar.
Answer:
627 / (13+6) = x so x = 33
Step-by-step explanation:
13 + 6 = 19, so if we divided 627 tons by 19 boxcars, each boxcar would weigh about 66 tons each.

Given the inequality 3(n − 6) < 2(n + 12), determine which integer makes the inequality false.
S:{−5}
S:{3}
S:{12}
S:{42}
I WILL GIVE BRAINIEST FOR THIS ONE!!
Answer:
The integer that makes the inequality false is D, 42
Step-by-step explanation:
Start the problem by expanding the inequality.
[tex]3\left(n-6\right) = 3n-3\times 6\\=3n-18\\----------\\2\left(n+12\right) = 2n+2\times 12\\=2n+24\\----------\\= 3n-18 < 2n+24[/tex]
Add 18 to both sides. When doing inequalities, always add the singular number or coefficient on the left side. Afterwards, simplify.
[tex]=3n-18+18 < 2n+24+18\\=3n\left(-18+18\right)\\=-18 + 18\\=3n-\left(0\right) < 2n+24+18\\=2n\left(24 + 18\right)\\=24 + 18\\=42\\=3n-\left(0\right) < 2n+42\\=3n < 2n+42[/tex]
Subtract by 2n, the coefficient on the right side.
[tex]3n-2n < 2n+42-2n\\=3n-2n < \left(2n+(42)-2n\right)\\= \left(2n+(-2n)\right)\\=3n-2n < 0+42-0\\3n-2n = 3-2\\= 1\\= "n"\\= 1n\\= 1\times n\\= 1\:or\:"n"\\= n < 42[/tex]
Given that n is less than 42, we can conclude that 42 would make the inequality false.
Hope this helps!

Question 14
Determine the distance between the points (−5, −3) and (−10, −8).
square root of 7 units
square root of 48 units
square root of 50 units
square root of 250 units
The measures are given as follows:
5. Total area: 2.102 x 10^7 km².
6. Distance between the points: square root of 50 units.
How to obtain the total area?The total area is obtained by the sum of the areas of each sea/ocean, given as follows:
South China Sea: 6.963 x 10^6 km².Artic Ocean: 1.4056 x 10^7 km².To add two numbers in scientific notation, the bases have to be equal, hence:
1.4056 x 10^7 = 14.056 x 10^6 (multiply the base by 10 and subtract by 1 the exponent.
Hence:
6.963 x 10^6 + 14.056 x 10^6 = 21.091 x 10^6 = 2.102 x 10^7 km².
How to obtain the distance between two points?The coordinates of the points are:
[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
The equation for the distance is of:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Hence the distance between the points (−5, −3) and (−10, −8) is of:
[tex]D = \sqrt{(-5 - (-10))^2+(-3 - (-8))^2} = \sqrt{50}[/tex]

Answer:
5. (a) 2.1019×10⁷ km²
14. (c) √50 units
Step-by-step explanation:
You want the total area of the South China Sea and the Arctic Ocean given their individual areas are 6.963×10⁶ km² and 1.4056×10⁷ km², respectively. And, you want the distance between the points (-5, -3) and (-10, -8).
5. AreaThe sum of the areas of the two bodies of water is ...
6.963×10⁶ km² +1.4056×10⁷ km² = (0.6963×10⁶ +1.4056) ×10⁷ km²
= 2.1019×10⁷ km² . . . . . total area
Both of the addends have a precision of 10³ km², so that precision is maintained in the sum.
14. DistanceThe distance between the points is found using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((-10 -(-5))² +(-8 -(-3))²) = √((-5)² +(-5)²) = √(25 +25)
d = √50
The distance between the points is √50 units.

Two data sets and their mean absolute deviations are shown.
Study the plots of each data set, and then use the drop-down menus to answer the questions below.
Answer:
Step-by-step explanation:
you don't have the option to what the drop downs say so I'm giving my best guess as to what they all say based on context.
-----------------------------------------------------------------------------------
Data Set B has distant outliers, so it has a lower MAD.
The smaller MAD of Data Set A suggests that most of the data is less than the mean that is in Data Set B
However, most of the data in Data Set A is (unknown) spread out from the mean than in Data Set B
Therefore, MAD is not reliable when there is an outlier.

I am unsure if these fit the answers the drop-downs give but they make the most sense given the context.

A sewing needle costs $0.09. Janice bought 12 sewing needles. How much did Janice spend in all?
Answer:
$1.08
Step-by-step explanation:
You would simply multiply $0.09 and 12. Decimals are frequently multiplied by treating them as whole numbers before placing the decimal point in the result. Where the decimal point is placed in the solution depends on how many digits are present in the factors following the decimal points. For instance, 0.3 x 0.8 equals 0.24.

If there are two parentheses in a PEMDAS equation and one has multiplication and the other has subtraction, which do I do first?
PLEASE HELP ASAP THIS IS DUE IN 1 HOUR I GIVE BRAINLIEST, FIVE-STAR RATING, A HEART, AND 50 POINTS TO ANYONE WHO CAN HELP ME WITHIN THE NEXT 45 MINUTES!!!
Answer:
First, simplify the parentheses. Then, do exponents. Next, multiply. Finally, add and subtract from left to right.
Step-by-step explanation:
Answer: You always complete multiplication and division before addition and subtraction, working left to right inside the parentheses first.
For example, if your equation was:
23 + (12 x 5 + 6 -7), then you would first complete the multiplication (12 x 5), then add 6 (+6), then subtract 7 (-7), and lastly add 23 (+23) which is outside the parentheses.
Your example:
40 ➗ 1 + 3 - (3 x 7) + (7 - 5)
First: (3 x 7)
second: (7 - 5)
third 40 / 1
fourth: 40 + 3
fifth: 43 - 21
sixth: 22 + 2
=24
Step-by-step explanation:
You should always follow the order of operations rule that follows a sequence of evaluation steps for a given expression. Remember the order using PEMDAS: Parentheses, Exponents, Multiplication, Division (from left to right), Addition, and Subtraction (from left to right). Therefore, you first complete work in the parentheses for multiplication & division (working left to right) and then addition and subtraction (working left to right). Then you complete any math (following the same order) outside the parentheses.

um what does this mean. Which number has factors besides 1 and itself?
Answer:
A composite number is a number that has at least one factor besides 1 and itself, or any number which is not prime (although the number 1 is neither prime nor composite). For example, 91 is a composite number. To determine whether a number is composite, determine whether or not it is prime.
Step-by-step explanation:
I don't know if this is the right answer or thread equation but here
"Which number has factors besides 1 and itself?"
Answer: Composite Number
A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.[1][2] Every positive integer is composite, prime, or the unit 1, so the composite numbers are exactly the numbers that are not prime and not a unit.[3][4]
For example, the integer 14 is a composite number because it is the product of the two smaller integers 2 × 7. Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself.
The composite numbers up to 150 are:
4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100, 102, 104, 105, 106, 108, 110, 111, 112, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 128, 129, 130, 132, 133, 134, 135, 136, 138, 140, 141, 142, 143, 144, 145, 146, 147, 148, 150.
