Since you are given two equations
y = 2x - 5
y = x^2 - 5
Substitute into one of the equations...,
;x^2 - 5 = 2x - 5
;x^2 - 2x = -5 + 5
; x^2 - 2x = 0
Hence you factorise the equation..,
; x(x - 2) = 0
Hence....x = 0 and 2
And for the value of y
; Substitute with the value of x onto one of either equations
for...x = 2
;y = 2(2) - 5....y = -1
for...x = 0
;y = 2(0) - 5....y = -5
Answer:
$156
Step-by-step explanation:
(9600 + 5376 )/ (8 * 12) = 156
Answer:
B

Answer:
3 or 4, I am confused
Step-by-step explanation:
I'll assume that f(x) = x2 – 2x + 8 is meant to be f(x) = x^2 – 2x + 8
Find the value of f(x) for x = 2:
f(x) = x^2 – 2x + 8
f(2) = (2)^2 – 2*(2) + 8
f(2) = 4 - 4 + 8
f(2) = 8
=============
From the graph, we can find that g(2) = 11
The differece between g(2) and f(2) is thus:
11 - 8 = 3
3 is not an option, so I wonder if the question is asking for the difference between the absolute maximum of g(x) and f(2). If so, the maximum for g(x) is 12, at x = 3.
This would lead to a difference of 12 - 8, or 4. This is still not an option, so I'm confused. Perhaps you can find my error and find the ciorrect answer, or at least one that appears in the options.
