Answer:
The rate of change of f(x) with respect to x is 1/4
Step-by-step explanation:
What this question simply ask is to find the slope of the line that passes through the two points
to find this, we use the slope equation
we have this as;
m= (y2-y1)/(x2-x1)
(x1,y1) = ((-15,-3)
(x2,y2) = (-7,-1)
m = (-1 + 3)/(-7 + 15) = 2/8 = 1/4
Answer:
x = 7
Step-by-step explanation:
Given
5x - 1 - 2x = 20, that is
3x - 1 = 20 ( add 1 to both sides )
3x = 21 ( divide both sides by 3 )
x = 7
Answer:
y = -0.4 + c
Step-by-step explanation:
y = mx + c (original form)
m ⊥ - 1/m
2.5 = 25/10
25/10 ⊥ -10/25
-10/25 = -0.4
y = -0.4x + c
Its choice d because 1^2 - 5(1) + 6
= 1 - 5 + 6
= 2
B = 7, a = 5. So a + b is 13.
