Here

  • a=18
  • d=-7

\\ \sf\longmapsto a_n=a+(n-1)d

\\ \sf\longmapsto a_{32}

\\ \sf\longmapsto 18+31(-7)

\\ \sf\longmapsto 18-217

\\ \sf\longmapsto -199

#2

  • a=4
  • d=6

\\ \sf\longmapsto a_{24}

\\ \sf\longmapsto a+23d

\\ \sf\longmapsto 4+23(6)

\\ \sf\longmapsto 4+138

\\ \sf\longmapsto 142

F(x) = 2x^2 - 5x - 15<br> g(x) = -2x - 1<br> find f(g(x)) ... somebody help me :(
Lapatulllka [165]

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

A furniture company makes large and small chairs. A small chair takes 30 minutes of machine time and 75 minutes of labor to buil
Radda [10]
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.

Help me solving number 22 &amp; 24. Thanks:)
aksik [14]

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

7y=28-4x

Substitute x=0 to find the y intercept

7y=28-4*0

=7y=28

=y=4

Substitute y=0 to find x intercept

7*0=28-4x

=0=28-4x

=4x=28

=x=7

Therefore,

x intercept is 7

y intercept is 4

The answer is C

<u>Question 24</u>

4y=7x+28

Substitute x=0 to find the y intercept

4y=7*0+28

=4y=28

=y=7

Substitute y=0 to find x intercept

4*0=7x+28

=0=7x+28

=-7x=28

=x=-4

Therefore,

x intercept is -4

y intercept is 7

The answer is B
