Solve the linear system using substitution. Show your work.
y = -3x + 3
4x +3y = -1

Answers

Sub y in the second equation by y in the first equation:
We get 4x+3(-3x+3)=-1
4x-9x+9=-1
-5x=-10
x=2
Sub in the first equation
y=-3(2)+3
y=-3

Answer:

x=2 and y=-3

Step-by-step explanation:

y=-3x+3, 4x+3y=-1 solve using substitution

y=-3x+3 solve y=-3x+3 for y

4x+3y=-1

4x+3(-3x+3)=-1 simplify both sides of the equation

-5x+9=-1

-5x+9-9=-1+-9 add -9 to both sides

-5x=-10

-5x/5=-10/-5 divide both sides by -5

x=2

substitute 2 for x in y=-3x+3

y=(-3)(2)+3

y=-3 simplify both sides of the equation

answer; x=2 and y=-3

Answer:3xx6x3x6xStep-by-step explanation:

x + 2x

= 1x + 2x

= (1 + 2)x

= 3x

2x - x

= 2x - 1x

= (2 - 1)x

= 1x

= x

4x + 2x

= (4 + 2)x

= 6x

6x - 3x

= (6 - 3)x

= 3x

5x + x

= 5x + 1x

= (5 + 1)x

= 6x

Answer:

8750

Step-by-step explanation:

Since the random sample contained 125 out of 500 people who voted for the dog park that is about 25%. since 25% of 500 is 125. If we scale that up to 25% of 3500 it would be 8750 people.

Answer:

The answer would be 8,750

Step-by-step explanation:

Out of a group of 500 from the 35,000, 125 people wanted a dog park. So find out how many groups of 500 are in 35,000. Which is 70 groups of 500. Since there's 70, you multiply 70 groups by 125

Describe the angle relationship and solve for the x.

Answers

Answer:

x = 25

Step-by-step explanation:

The shown angles appear to be on a straight line

Angles on a straight line have a sum of 180°

That being said we can create an equation using this relationship

180 = x + 2 + 153

now we solve for x using basic algebra

step 1 combine like terms

153 + 2 = 155

now we have 180 = x + 155

step 2 subtract 155 from each side

180 - 155 = 25

155 - 155 cancels out

we're left with x = 25

Answers

Your answer is 10+5x

Because 5x2=10
And 5 times x= 5x

Answer:

10+5x

Step-by-step explanation:

The distributive property is where you multiply what's on the outside with ALL the terms on the inside.

Here, you have to multiply 5 by two terms on the inside: 2 and x. 5*2 is 10 and 5*x is 5x. Add them together and your answer is 10+5x (or, 5x+10).

A data set has a mean of 7, a median of 5, and a mode of 8. Which of the numbers (7, 5, or 8) must be in the data set?

If possible, please explain in words, thank you. :)

Answers

5 must be in the data set: median means it’s the middle number in the set. so if the data was [2,3,5,6,7], 5 is the median.

8 has to be in the data set because 8 had to be there to be a mode were you can have 5 as the median if the set was like this 234678 because 4&6 both are in the middle so you have to do the middle of that which is 5 so that’s the median without having the number 5.
