Evaluate the piece-defined function for the given of x by matching the domain values with the range values

Elenna [48]

Answer:

The correct answer is:

(1) d

(2) b

(3) a

(4) c

(5) e

Step-by-step explanation:

The given problem is incomplete. Find the attachment of the full question.

According to the question,

(1)

By putting x = -2, we get

$f(x)=(-2)^3-5$

$=-8-5$

$=-13$

(2)

By putting x = 0, we get

$f(x)=(0)^3-5$

$=0-5$

$=-5$

(3)

By putting x = 3, we get

$f(x)=8$

(4)

By putting x = 9, we get

$f(x)=(2)^{9-7}$

$=(2)^2$

$=4$

(5)

By putting x = 11, we get

$f(x)=(2)^{11-7}$

$=(2)^4$

$=16$

If m angle acd = 120- x, m angle b = 60, and m angle a = 10 + x, find m angle acb

lesya [120]

Answer:

ACB = 85

Step-by-step explanation:

First find x:

10+ x + 60 = 120 - x

x + 70 = 120 - x

Add x to both sides

2x + 70 = 120

subtract 70 from 120

2x = 50

Divide 2 from both sides

x = 25

10 + 25 + 60 = 95

Subtract 95 from 180

ACD = 85

4n+6-2n=2n+6 then collect the like terms
(4n-2n-2n=0)
0n=0

2(3b-4)=4b-11
6b-8=4b-11 collect the like terms
(6b-4b=2b)(-11+8=-3)

answer
2b=-3 then divide both sides by 2
b=-1.5

Write an equation for the line parallel to the given line that contains C. C (1,8); 5/7x + 7

Genrish500 [490]

-------------------------------------------------------------------------------------------------------------

Answer: $\textsf{y = 5/7x + 51/7}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Goes through (1, 8) and is parallel to y = 5/7x + 7}$

Find: $\textsf{Write an equation that follows that criteria}$

Solution: We know that our equation is going to parallel to the line that was given therefore the slope would stay the same at 5/7. We also have a point so we can plug in the values into the point-slope form, distribute, and solve for y.

Plug in the values
