Subtract 7 both sides
Subtract 9x both side
They cancel out
At the end you divide it
I don’t have access to paper right now sorry
Answer:
(0,0)
Step-by-step explanation:
x value of vertex = -b/2a
ax^2+bx+c
-2x^2+0x+0 sinc you have no value of b & c in your quadratic function
-b = 0
2a = (2)(-2)
-b/2a = (0/-4) = 0
x value of the vertex = 0
plug 0 in for all values of x in the function to find y coordinate value
-2(0)^2 = 0
(x,y) = (0,0)
Answer:
Step-by-step explanation:
Given
w is the classmate's weight in pounds
h is the height
The general formula for the expression is y = MX+c where
m is the slope
c is the intercept
M is the change in y to change in x
Comparing with the given equation
w = 6.5h - 275, we will see that the slope of the equation is 6.5 and can be expressed as the change in the classmate's height to the classmate's weight
slope = dh/dw = 6.5
Then a is Half of 45 wich is 22.5 I believe.
