Answer:
Step-by-step explanation:
Air pressure is measured in pascals. For a professional American football game, the ball should be inflated to about 90,000 pascals. Scientists studied the effects of air temperature on the pressure inside American footballs by taking these steps:
1. Prepare 100 footballs.
2. Measure each football's air pressure.
3. Divide footballs into 10 groups.
4. Place the groups in different lockers cooled to different air temperatures.
5. After 12 hours, remove the footballs from lockers.
6. Measure each football’s pressure again.
7. Compare the new pressures to the starting pressures.
What two terms best describe the variable "air pressure inside the football" in this experiment?
independent, qualitative
independent, quantitative
dependent, qualitative
dependent, quantitative
P=S1+S2+S3
P=2.3x+14+2x-0.2x+15
P=4.1x+29
The answer is the first one

You found it out already but yeah
Answer:
C. y = -4x +10
Step-by-step explanation:
Equation of a line is found by the formula y = mx +b
Where m is the slope and b is the y intercept
we see that y-intercept is given as 10, so b = 10 and we plug in the coordinate (2,2) into the equation to find the slope (m). We plug in x = 2 and y = 2. Shown below:
<em>We know the value of m to be -4 and b to be 10, thus we can write the equation as:</em>
Answer choice C is right.
