Answer:

C. The y-intercepts of the two functions are opposites.

Step-by-step explanation:

The y-intercept of g(x) is -1 and the y-intercept of h(x) is 1. -1 and 1 are opposites, so the two y-intercepts are also opposites.

Answer:

Step-by-step explanation:

-2x + 8 = 4

-2x = 4 - 8

-2x = - 4

x = - 4/-2 = 2

replace x with 2 on the equation

-4-4=4

so answer is no

-8=4 not possible

Answer:

The width of Dana's living room is 16 feet.

Explanation:

Because Dana's living room is rectangular and we are given the length of one side and the length of the diagonal we can use the Pythagorean Theorem to solve this problem.

For a right triangle which the length, width and diagonal make up the Pythagorean Theorem states:

a

2

+

b

2

=

c

2

Let the length of 12 be

a

and because the diagonal is the hypotenuse of the triangle (the side opposite the right angle) we let

c

be 20. Substituting and solving gives:

Answer:

c. 80

Step-by-step explanation:

cos x = sin(x-70)

cos x = cos [90-(x-70)]

cos x = cos (90-x +70)

cos x = cos 160 -x

x= 160-x

2x = 160

x =80

Answer:

tan y°

Step-by-step explanation:

by using the Sine Rule (See attached), we can form the equation:

[tex]\frac{r}{sin (y)} = \frac{p}{sin (x)}[/tex]

rearranging this, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(x)}[/tex]   ---------------------eq 1

Recall that all internal angles of a triangle must sum to 180°. we observe that we have a right triangle where one of the angles is 90°. It then follows that the sum of the other two angles must sum to 90°

i.e x + y = 90°

with a little rearranging, we get

x = (90° - y)

Substituting this into eq 1 above, we get:

[tex]\frac{r}{p} =\frac{sin(y)}{sin(90- y)}[/tex]  ---------eq 2

recall that from the trigonometric co-function identities,

sin (90°- y) = cos y

substituting this into eq 2 gives :

[tex]\frac{r}{p} =\frac{sin(y)}{cos(y)} = tan(y)[/tex]   (answer)

Answer:

162

Step-by-step explanation:

a=[tex]\frac{a+b}{2} h[/tex]

a=base and the base is 13 ft.

b= also means base which is 23 ft.

h= height which is 9 ft.

so 13+23 is 36

36/2 is 18

and 18 times 9 is 162

sorry for the lengthy answer but i hope this helps :) have a nice day !!

D is your answer i believe

Step-by-step explanation:

using g(x), -1, which is our change of x will go right. -5 is our change in y, so therefore it goes down. negative means down, positive means up for our change of y. for our change of x, negative goes right, and postive goes left. thats why i think the answer is d

Answer:
