Answer:

y = 2x - 1

Step-by-step explanation:

The line passes through point (-7,-8)

The line is parallel to line whose equation is 2x - y = 6

Converting the equation of the second line into form y = mx + c;

2x - y = 6 is equal to y = 2x - 6 (the slope of this line is 2)

For parallel lines the value of their slopes is the same.

So our first line passes through point (-7,-8) and has a slope of 2

Taking another point (x,y) on the line;

Slope = Change in y ÷ change in x = \frac{y - - 8}{x - -7} = 2

y + 8 = 2x + 7

y = 2x + 7 - 8

y = 2x - 1

Answer:

see the procedure

Step-by-step explanation:

Identify

Let

x ---> the cost of the Xbox one at Walmart

Strategy

we know that

The cost of the Xbox one at Walmart multiplied by 2 plus $50 must be equal to $450

Set up

The algebraic expression that represent this situation is

450=2x+50

Solve

solve for x

450=2x+50

2x=450-50\\2x=400\\x=\$200

Check

substitute the value of x in the equation

450=2(200)+50

450=450 ----> is ok

Aleonysh [2.5K]

The mathematical sentence can be written as:

x^3 = y^5

<h3>How to write the expression?</h3>

A number a to the power of n is written as:

a^n

Then:

"x to the power of 3 is equal to y to the power of 5"

Would be written as:

x^3 = y^5

Particularly, this does not appear in the given options, but this is the correct and simplest way of writing the given mathematical sentence.

Answer:

B. {–3, 5.9, 8.3}

Step-by-step explanation:

The domain is the set of all the values of  

x .The range is the set of all the values of  y .

Domain: { 3.2 , 7.6 , 1.4 , − 9.1 }

Range: { − 3 , 5.9 , 8.3 }

Answer:

range is -3, 5.9 , 8.3

Step-by-step explanation:

{(3.2, –3), (7.6, 5.9), (1.4, –3), (–9.1, 8.3)}

We are given with set of ordered pairs (x,y)

In each ordered pair, x is the domain and y is the range

for domain , take all the x  values (first number) from the ordered pairs

for range, take all the y value (second number) from the ordered pairs

y values of the ordered pairs are -3, 5.9, -3, 8.3

So range is -3, 5.9 , 8.3
