Which linear equation shows a proportional relationship?
A: y equals negative 2 times x minus one fifth
B: y equals two thirds times x minus 1
C: y equals 4 times x plus 6
D: y equals three fourths times x
The linear equation shows a proportional relationship is y= 3/4 x.
What is Constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
As, we know the constant of proportionality standard form is
y= kx
where k is constant of proportionality
So, from the given options the relation of constant of proportionality shown by
y= 3/4 x
where k = 3/4.

Which expression is equivalent to 4(−2.3y − 12.4)? best answer gets brilliant
−9.2y − 12.4
−9.2y − 49.6
−1.7y − 8.4
−1.7y − 12.4
Answer:
b) -9.2y - 49.6
Step-by-step explanation:
Given expression,
→ 4(-2.3y - 12.4)
Simplifying the expression,
→ 4(-2.3y - 12.4)
→ (4 × -2.3y) - (4 × 12.4)
→ -9.2y - 49.6
Hence, option (b) is correct.

What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
I have 2 pairs of parallel sides, but here I have 1 pair of sides that never cross.
Now,
Since, We know that;
In the trapezium, it has only one pair of parallel lines.
And, In a square it has two pairs of parallel lines.
Thus, Here the shape is Trapezium.

5: You need to turn 8 into a fraction over 8. 8*3 = 24, so 24/3. There are 24 1/3 cups in 8.
6: She can fill more than 8 tortillas
8: This one ties back to #5, with the 24/3. You divide 24 by 2, so 12. You'll have 12 groups with 24 pieces in total. (Circle 12 groups of 2)
9: 8 / (2/3) is the same as 8*3/2 which equals 12. 12 tortillas.
10: To get a common denominator for 12/8 and 3/4, you can convert 3/4 to 6/8 [3/4 = 6/8] And since 6 is half of 12, 12/8 - 6/8 = 6/8. Mike can only fill 2 glasses

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:

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.

(Graphing Proportional Relationships MC)
The equation c equals one third times s represents the proportional relationship between the number of bags of cement (c) and the number of bags of sand (s) required to make concrete. A graph of this relationship is shown.
Which statement is true?
The proportional relationship is graphed correctly.
The graph does not show a proportional relationship.
Bags of Sand should be on the x-axis, and Bags of Cement should be on the y-axis.
The axes are labeled correctly with the independent and dependent variables.
Answer:
Bags of Sand should be on the x-axis and bags of Cement should be on the y-axis
Step-by-step explanation:
c = 1/3s
When we have 3 sandbags, we should have 1 cement bag (1,3)
When we have 9 sandbags, we should have 3 cement bag (3,9)
The points are plotted correctly, the labels for both axes are just switched
Answer: Bags of Sand should be on the x-axis and bags of Cement should be on the y-axis
