If B is the midpoint of AC, and AC = 8x-20, find BC.

Answers

Step-by-step explanation:

B is the midpoint of AC, where all 3 points are on the same line.

This means that AB = BC and AB + BC = AC, which is equals to 8x - 20.

Hence, BC = 0.5(8x + 20) = 4x + 10.

Luis has a biweekly gross pay of $770 and claims 2 federal withholding allowances. Luis has all of the following deductions from his gross pay:HEEEEEEEELLLP ASAAP! PLZZZZ

Answers

Answer:

the answer is D

Step-by-step explanation:

took the test

Multiply the gross pay by 26 to receive the annual pay which would be $770*26=$20,020. The payer claims 2 allowances, so you take $4,050 and multiply it by 2 and get a $8,100 annual pay deduction.

Proportional constant

Answers

Answer:

The value of the proportionality constant (y to x) is: 3/10

Step-by-step explanation:

We know the slope of any graph where 'y' varies directly with 'x' gives us the constant of proportionality 'k'.

i.e. y = kx

and k = y/x

Given the points

(100, 30)

(300, 90)

(500, 150)

We know that the proportionality constant (y to x) is:

k = y/x

For the point (100, 30)

k = 30/100=3/10

For the point (300, 90)

k = 90/300=3/10

For the point (500, 150)

k = 150/500=3/10

As the value of proportionality constant (y to x) is the same.

i.e. k = 3/10

Thus, the value of the proportionality constant (y to x) is: 3/10

1. If the expression 9y − 5 represents a certain number, which of thefollowing could NOT be the translation?

a. five less than nine times y

b. five less than the sum of 9 and y

c. the difference between 9y and 5

d. the product of nine and y, decreased by 5

Answers

After examining all options, we find that each one can be represented by the expression 9y - 5. Therefore, there is no option that could NOT be the translation of the given expression.

To find the translation that could NOT be represented by the expression 9y - 5, we need to compare each option with the given expression and determine if they are equivalent or not.

The given expression is: 9y - 5

Now, let's examine each option:

a. five less than nine times y

This option can be represented as 9y - 5, so it is equivalent to the given expression.

b. five less than the sum of 9 and y

This option can be represented as 9 + y - 5, which simplifies to 9y - 5. So, it is also equivalent to the given expression.

c. the difference between 9y and 5

This option can be represented as 9y - 5, so it is equivalent to the given expression.

d. the product of nine and y, decreased by 5

This option can be represented as 9y - 5, so it is also equivalent to the given expression.

What is the equation, in point-slope form, for a line that goes through (2, -6) and hasa slope of 3/5
A. y - 6 = 3/5 (x + 2)

B. y - 2 = 3/5 (x + 6)

C. y+2 = 3/5 (x – 6)

D. y+6= 3/5 (x - 2)

Answers

Answer: D

Explanation:

Point slope form:

(y - y1) = m(x - x1)

Coordinate given = (2,-6)
Slope = 3/5

Thus:
(y -(-6)) = 3/5(x - 2)
y + 6 = 3/5(x - 2)
