Answer:
Slope= 30
Step-by-step explanation:
What does the slope tell me?
It tells me that every time I try to find the slope with different points I get 30 for slope.
Given:
(x₁,y₁) = (-2,4)
(x₂,y₂) = (0,2)
Determine the slope of the function
m = (y₂ - y₁) / (x₂ - x₁)
m = (2 - 4) / (0 + 2)
m = -2/2
m = -1
Determine the equation
y - y₁ = m(x - x₁)
y - 4 = -1(x - (-2))
y - 4 = -1 (x + 2)
y - 4 = -x - 2
y = -x - 2 + 4
y = -x + 2
f(x) = -x + 2
The correct answer is first option
If they are the sides then2x=x+26
2x-x=26
x=26
so each side =2*26=52
Answer:
15 minutes
Step-by-step explanation:
The formula is
1/a + 1/b = 1/c to determine joint time where a and b are the times alone and c is the time together
1/10 + 1/ 30 = 1/c
Multiply each side by 30c to clear the fractions
30c( 1/10 + 1/ 30) = 1/c * 30c
3c + c = 30
4c = 30
Divide by 4
4c/4 = 30/4
c = 7.5 minutes
This is the time for 50 pages
We want 100 pages, so multiply by 2
7.5 *2 = 15 minutes
m = -1
Step-by-step explanation:
-16m = 7 + 9
-16m = 16
m = 16 ÷ -16
m = -1
