Answer:
9/4
Step-by-step explanation:
2(x - 10) + 4 = -6x + 2
2x - 20 + 4 = -6x + 2
2x - 16 = -6x + 2
8x - 16 = 2
8x = 18
x = 18/8 or 9/4
Answer:
the answer is C
Step-by-step explanation:
2(x-10) +4 = -6x + 2
2x-20 +4= -6x +2
2x-16 = -6x+2
+16 = +16
______________
2x = -6x + 18
+6x = +6x +18
_____________
8x =18
x=2.25 or 9/4

Find the missing angle or find X?
Answer:
x = 45
Step-by-step explanation:
Interior angles of a triangle sum up to 180
180 - 90 = 90
90 / 2 = 45
Answer:
X = 45
Step-by-step explanation:
Since all interior angles of a triangle add up to 180 and both of the missing angles are the same value, X would equal 45,
90+45+45=180
What is the best name for polynomial with 3 terms that has a degree
Answer:
Names of Degrees
Degree Name Example
1 Linear x+3
2 Quadratic x2−x+2
3 Cubic x3−x2+5
4 Quartic 6x4−x3+x−2
Answer:
Quartic Trinomial
Step-by-step explanation:
Monomial = one term
Binomial = two terms
Trinomial = three terms
Polynomial = four or more terms
As the other answer says, the order for degrees is:
Linear - to first degree
Quadratic - to second degree
Cubic - to third degree
Quartic - to fourth degree
Quintic - to fifth degree
Anything above fifth degree is just said "__th degree"
Example: x^7 + x^2 + 5 would be seventh degree trinomial

In a lab experiment, 830 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 28 hours. How many bacteria would there be after 13 years, to the nearest whole number?
Answer:
1145
Step-by-step explanation:
830(2) 28/13
^ do that ok??????? plug it in!!!!!!!!
then do u know what u will get? u will get this !!!!!! y = 1145.09631989
round 2 da whole numba and den boom shakalaka B ) i got my question wrong so that i could put the right answer here. bye yall
The number of bacteria doubling every 28 hours will be 1145 after 13 hours.
What is the formula for exponential growth and exponential decaying function?The formula for exponential growth is y = y₀.e^(kt).
The formula for exponential decay is y = y₀.e^(-kt).
In the case of doubling the growth of bacteria, we can use the formula,
[tex]y_f = y_0\times2^{\frac{t_r}{t}[/tex], where [tex]y_f[/tex] represents the final population, [tex]y_0[/tex] is the initial population, [tex]t_r[/tex] is the time we are required to determine, and [tex]t[/tex] represents the time rate growth.
Therefore from the given information, the number of bacteria after 13 hours will be,
[tex]y_f = 830\times2^{\frac{13}{28}[/tex].
[tex]y_f = 830\times1.38[/tex].
[tex]y_f = 1144.86[/tex] or 1145 bacterias.

4x=180-3
4x/4x=177/4x

Answer:
=78 degrees
Step-by-step explanation:
complementary angles add up to 90 degrees
A + B = 90
3x + 9 + x - 11 = 90
3x + x + 9 - 11 = 90
4x - 2 = 90
collect like valuables
4x = 90 + 2
4x = 92
x =23
angle A = 3x + 9
= (3 x 23) + 9
= 69 + 9
= 78

Answer:
Step-by-step explanation:
Scale factor = 1 : 7
a)Let the length of the house in the scale drawing = x
1:7 :: x : 21
Product of means = Product of extremes
7*x = 1* 21
x = [tex]\frac{1*21}{7}[/tex]
x = 3
Length of the house in the scale drawing = 3 in
b) Height of the real house =y
1 : 7 :: 4 : y
Product of extremes = product of means
1 * y = 7*4
y = 7*4
y = 28
Height of real house = 28 feet

Answer:
A. 112°Step-by-step explanation:
Angles QPS and QRS are supplementary as opposite angles of a cyclic quadrilateral.
Supplementary angles sum to 180°.
m∠QPS = 180° - m∠QRSm∠QPS = 180° - 68°m∠QPS = 112°Correct choice is A

PLZ HELP PLZ (1a) Use long division to show the fraction and decimal in each pair are equivalent? 3/4 & 0.75. Hint: Divide 3/4.
Answer:
3 divided by 4 will equal 0.75 which is equivalent to 0.75. or you can do 6/8 which will also equal 0.75. and 6/8 is equivalent to 3/4. so therefore it's confirmed that 3/4 is equivalent to 0.75
Suzanne, Latisha, and Morgan measure their heights. Suzanna is 0.8 times the height of Latisha, and Morgan is 1.09 times the height of Latisha. Who is the tallest? Who is the shortest?
Answer:
Tallest = Morgan
Shortest = Suzanna
Step-by-step explanation:
Assuming Latisha = 1
0.8 is less than 1, meaning it's 80% the height of Latisha, so this means Suzanna is shorter than Latisha.
1.09 is more than 1, Morgan is taller than Latisha.
Morgan is tallest and Suzanna is shortest, Latisha in the middle.

Last week, Juliet ran 22 kilometers. This week, she plans to run 2\frac{2}{5}2 5 2 times as far as last week. How many kilometers does Juliet plan to run this week?
Answer: 52.8 kilometers
Step-by-step explanation:
This week she plans to run 2²/₅ times as much as last week.
If she ran 22 kilometers last week, then multiple 22 by 2²/₅ to find out the number of kilometers to run this week.
First convert the improper fraction to a proper one:
2²/₅ = 12/5
= 12/5 * 22
= 264/5
= 52.8 kilometers
The length of a rectangle is 8 inches more than the width. The area of the rectangle is 33 square inches. What is the length of the rectangle?
Step-by-step explanation:
Put x as the width and x+8 as the length. The equation would be x(x+8)=33 and it would factor out as (x-3)(x+11). The width is 3 and the length is 11. The perimeter would be 28.

During the Martinez family trip, they drove from home to a ski lodge, a distance of 52 4 5 miles, and then drove an additional 14 4 5 miles to visit friends.
Answer:
[tex]134 \frac{6}{5}[/tex]
Step-by-step explanation:
The computation of the distance travelled is shown below:
Total distance would be
[tex]= 52 \frac{4}{ 5} + 14 \frac{ 4}{5}\\\\= \frac{264}{5} + \frac{74}{5}\\\\= \frac{338}{5}[/tex]
Now if the same route would taken again in order to back home
So, the total distance would be doubled
[tex]= \frac{338}{5} \times 2\\\\ = \frac{676}{5} \\\\= 134 \frac{6}{5}[/tex]
Using the graph to the right, write the ratio in simplest form BC/BD
