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 - 3x

= (6 - 3)x

= 3x

5x + x

= 5x + 1x

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

7.5, 25, and 14.1

I believe

Answer:

1: 7.5 2: 25 3: 14.2

Step-by-step explanation:

For all of these, you want to use the Pythagorean Theorem, which is a^2+b^2=c^2

1. you would have to plug in 13 for b, and 15 for c, because 15 is the hypotenuse

a^2+13^2=15^2

now, solve for a

a^2+169=225

225-169=56

a^2=56

to undo a squared, you have to take the square root of both sides

sqrt(56) is about 7.5

to check, you would have to plug in 7.5 for a

2. you would start off the same way, but this time we are solving for c

15^2+20^2=c^2

225+400=c^2

625=c^2

take the square root of 625

25 is your answer

if you want to check, plug in 25 for c

3. we are trying to find the hypotenuse again, so we are solving for c

5.1^2+13.2^2=c^2

26.01+174.24=200.25

200.25=c^2

take the square root once again

it is approximately 14.2

if you want to check, plug in 14.2 for c

have a great day!
