PART A:
Solve for the slope by solving change in y over change in x. We have (3-(-5)/(-2-2) = 8/-4=-2
PART B:
Change in to y=mx+b: -5y = -2x-10. Divide all terms by -5: y = 2/5x + 2. The slope is 2/5 and the y-intercept is 2.
PART C:
Remembering from part a that m=change in y/change in x, we have the equation: -4=1-(-9)/0-x. If we simplify, we have -4=10/0-x. If we multiply both sides from 1/10 we have: -2/5 = -x. So, x = 2/5.
PART D:
We can use point-slope form first:
y-5=-7(x+1). Then we solve the equation! y-5 = -7x-7. After adding 5 to both sides, we have the equation: y=-7x-2.
Answer:
Step-by-step explanation:
Given equation:
To solve for the unknown variable 
.
Solution:
In order to solve for , we will isolate alone on one side by carrying out math operations to both sides.
We have:
Subtracting both sides by 88.1
Dividing both sides by -2.3
∴ (Answer)
Answer:
E, C, B

Each of these is independent to any car.
Answer: x + 0.8 = 101.1
Step-by-step explanation:
Let x represent Connor's temperature last night. Connor's temperature was 0.8 degrees Fahrenheit higher this morning than it had been last night. This means that his temperature this morning will be
x + 0.8 degrees Fahrenheit
His temperature this morning was 101.1 degrees Fahrenheit. Therefore, the equation of the situation will be
x + 0.8 degrees Fahrenheit = 101.1 degrees Fahrenheit
Answer:
h(3) = 1
Step-by-step explanation:
To find h(3), that is the value of h(x) when x = 3
Locate x = 3 on the x- axis, go vertically up to meet the graph of h(x) at (3, 1 )
Thus when x = 3, y = 1, that is
h(3) = 1
