Answer:
f(x) = -2x +7
Step-by-step explanation:
The 2-point form of the equation for a line is suitable for this. For points (x1, y1) and (x2, y2), the equation is ...
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
For the given points (0, 7) and (3, 1), the equation is ...
y = (1 -7)/(3 -0)(x -0) +7
y = -6/3x +7 . . . . . . . . simplify.
We can use f(x) for y to get ...
f(x) = -2x +7

Step-by-step explanation:
<u>Area Of A Cube
</u>
Suppose a cube with side length s, the area of one side is

Since the cube has 6 sides, the total area is

But if we have the area, we can solve the above formula for s to get


We have two different cubes with areas 1,200 square inches and 768 square inches. Let's compute their side lengths




The difference between them is

The side of the cube with area 1,200 square inches is
longer then the side of the cube with area 768 square inches
-7(2)+y=60
-14+y=60
y=60+14
Y=74

A.
Step-by-step explanation:
Answer: Median= 91; 8th quiz score=86
Step-by-step explanation: The sum of the scores is 8×92=736. Subtract the 6 given scores and then a 100 for the seventh quiz to find the score she got on the 8th quiz, this is an 86. Now that you have all the scores, arrange them all in the least to greatest order and find the average of the middle two numbers (median), which is 91!
