Answer:

y=2/3x-4

Step-by-step explanation:

y=mx+b is slope intercept form so the y intercept is -4, which is b in the equation. so y=mx-4 and then m is the slope which is 2/3 so

Determine the slope and y -intercept for each line shown. Then write the equation of the line (will give Brainliest)

Pavlova-9 [17]

Answer:

$y=\frac{1}{4}x+2$

m= $\frac{1}{4}$

b= 2

$y=-\frac{1}{3}x+1$

m= $-\frac{1}{3}$

b= 1

$y=3x+4$

m= 3

b=4

Step-by-step explanation:

1. The line intersects the y-axis at the point (0,2) therefore its y-intercept is b=2.

The line rises up 1 unit on the y-axis for every 4 units on the x-axis therefore the line has a slope of m=1/4.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that $y=\frac{1}{4}x+2$

2. The line intersects the y-axis at the point (0,1) therefore its y-intercept is b=1.

The line down up 1 unit on the y-axis for every 3 units on the x-axis therefore the line has a slope of m= -1/3.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that $y=-\frac{1}{3}x+1$

3. The line intersects the y-axis at the point (0,4) therefore its y-intercept is b=4.

The line rises up 3 units on the y-axis for every 1 unit on the x-axis therefore the line has a slope of m=3.

Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that $y=3x+4$

What is the value of x? (x + 40)° (3x)° A. 20 B.35 C. 60 D. 70

Olenka [21]

Hello!

We are given the equation below.

x+40=3x

We want to get all of the variables on side. First of all let's subtract 40 from both sides.

x=3x-40

Now we rearrange our equation so the commutative property will work.

x=3x+(-40)
x=-40+3x

Now we subtract 3x from both sides.

-2x=-40

We divide both sides by -2.

x=20

Our answer is A) 20.

I hope this helps!

at the movie theatre, child admission is $5.20 and adult admission is $9.00. on Monday, 132 tickets were sold for a total sales

kakasveta [241]

Answer:

That day 51 child tikets were sold

Step-by-step explanation:

To do this problem we have to make 2 equations, one that represents the number of entries and the other that represents the money

x = child tickets

y = adult tickets

x + y = 132

x * $5.20 + y * $9.00 = $994.20

First we have to solve for the x in the first equation

x + y = 132

x = 132 - y

Now we replace the x with (132 - y) in the second equation

x * $5.20 + y * $9.00 = $994.20

(132 - y) * 5.20 + y * 9.00 = 994.20

686.4 - 5.2y + 9y = 994.2

-5.2y + 9y = 994.2 - 686.4

3.8y = 307.8

y = 307.8/3.8

y = 81

We replace y with its value in the first equation

x = 132 - y

x = 132 - 81

x = 51

That day 51 child tikets were sold
