Answer:
20
Step-by-step explanation:
locate 10 on the horizontal (x- axis), go vertically up to meet the line at (10, 20)
The corresponding output is the value on the vertical (y- axis )
That is the output is 20
Answer:
-3/4
Step-by-step explanation:
Write in y = mx + b form
4y = -3x + 8
y = -3/4x + 2
Find the m value.
m = -3/4
Answer:
89 miles per hour
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Given a parabola in standard form, y = ax² + bx + c ( a ≠ 0 ), then
minimum/ maximum value is the y- coordinate of the vertex.
The x- coordinate of the vertex is
= - 
y = x² - 
x + 
← is in standard form
with a = 1 and b = - , thus
= - 
= 
Substitute this value into y
y = ( )² - ( ) +
= 
- 
+ = 
Since a > 1 then the vertex is a minimum, thus
minimum value = → A
The answer would be 59.
Because the first point is (0, 59) I am positive on this answer. Hope this helps!
