Answer:
f(g(x)) = 8x² + 18x - 8
Step-by-step explanation:
Substitute x = g(x) into f(x) , that is
f(g(x))
= f(- 2x - 1)
= 2(- 2x - 1)² - 5(- 2x - 1) - 15
= 2(4x² + 4x + 1) + 10x + 5 - 15
= 8x² + 8x + 2 + 10x - 10
= 8x² + 18x - 8
4 1/4 is a rational number
Let the number of large chairs be x and small chairs be y
40x + 30y = 26 x 60 = 1,560 . . . . (1)
80x + 75y = 57 x 60 = 3,420 . . . . (2)
(1) x 2 => 80x + 60y = 3,120 . . . . (3)
(2) - (3) => 15y = 300 => y = 300/15 = 20
From (2), 80x + 75(20) = 3,420 => 80x + 1,500 = 3,420 => 80x = 3,420 - 1,500 = 1,920 => x = 1,920/80 = 24
Therefore, the company should produce 24 large chairs and 20 small chairs.
Answer:
Question 22
x intercept is 7
y intercept is 4
The answer is C
Question 24
x intercept is -4
y intercept is 7
The answer is B
Step-by-step explanation:
x and y intercepts are the points at which the graph meets x and y axes.
x and y intercepts can be found the following way,
y intercept - substitute 0 to x
x intercept - substitute 0 to y
Question 22

Substitute x=0 to find the y intercept

=
=
Substitute y=0 to find x intercept

=
=
=
Therefore,
x intercept is 7
y intercept is 4
The answer is C
<u>Question 24</u>

Substitute x=0 to find the y intercept

=
=
Substitute y=0 to find x intercept

=
=
=
Therefore,
x intercept is -4
y intercept is 7
The answer is B
