54 i believe
explanation: if you put 18 crayons in 3 baskets each it’s gotta b 54
f(x) is concave down on an interval I if all of the tangents to the curve on I are above the graph of f(x)
-9×+1=-×+17
-9×=-×+16 (subtract 1 from both sides)
-8×=16 ( add x to both sides)
×=-2 (divide -8 from both sides)
Answer:
d. y = x + 6
Step-by-step explanation:
Equation of AD can be written in the slope-intercept form, y = mx + b
First, find the slope (m) and y-intercept (b) of line AD.
✔️Slope (m) = change in y/change in x
Using two points on line AD, (-5, 1) and (0, 6):
Slope (m) = (6 - 1)/(0 - (-5))
Slope (m) = 5/5
m = 1
✔️y-intercept (b) is the point where the line cuts across the y-axis = 6
b = 6
✔️To write the equation, substitute m = 1 and b = 6 into y = mx + b
y = 1(x) + 6
y = x + 6
