Write an equivalent expression that uses only addition.

20−9+8−7

Answers

Answer 1

Answer:

2+1+3+2+1+3

Step-by-step explanation:

:)

Answer 2

Answer:

20 + -9 + 8 + -7

Step-by-step explanation:

A epression DOES NOT have a equal sign,  =

20-9+8-7 = 12

20 + -9 + 8 + -7

to check -->

20 +-9 + 8 + -7

20 + -9 = 20 - 9 = 11

11 + 8 = 19

19 + -7 = 19 - 7 = 12

So therefor it would be

20 + -9 + 8 + -7

I don’t think it’s a function

Answer:

it is not a function

Step-by-step explanation:

if you can pass a vertical line through more than one point it is not a function, you have two points with the same x and different y

(-13,4) and (-13,9)

because you have two different y values for the same x it would fail the vertical line test and thus is not a function

Amelia builds and sells birdhouses. The difference between the amount she sells each birdhouse for and the cost of supplies to build each birdhouse is $20. Amelia also spends $45 on tools to build birdhouses. Which equation can Amelia use to calculate the amount of money (m), in dollars, she earns from selling b birdhouses?

Answers

Answer:

[tex]m= 20b-45[/tex]

Step-by-step explanation:

Given data

The difference between the amount she sells each birdhouse for and the cost of supplies to build each birdhouse is $20

This means that her profit = $20

the number of birdhouses = b

cost of tools= $45

Hence the amount she earns from selling b houses is given as

[tex]m= 20b-45[/tex]

write an equation to represent this function. use function notation.

Answers

Answer:

[tex]L(x) = 360 - 15 w[/tex]

Step-by-step explanation:

See comment for complete question

Given

[tex]Amount = \$360[/tex]

[tex]Rate = \$15[/tex] weekly

Required

Determine the function to represent the scenario

The amount (L) owed in w weeks is represented as:

[tex]Amount\ Owed = Amount - Rate * Weeks[/tex]

We used negative because the amount reduces weekly.

So, we have:

[tex]L(w) = 360 - 15 * w[/tex]

[tex]L(x) = 360 - 15 w[/tex]

Write the equation for the line that passes through (2, -4) and is
perpendicular to the line to x - 4y = 7.

Answers

Answer: y= x-2

Step-by-step explanation:

Perpendicularity entails the slope of line a is -1 divided by the slope of line b

m1= (-1/m2)

From y=Mx +c

We compare with x-4y=7

y=(1/4)x-7/4

Meaning m2= 1/4

m1= -1/(1/4)= -1*4= -4

((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1

x1= 2, y1= -4

((y-(-4))/(x-2))= -4

((y+4)/(x-2))= -4

Cross multiply

y+4= -4(x-2)

y= x-2
