Solve the system of equations by the substitution method.

Mathematics
1 answer:
victus00 [196]3 years ago
3 0

Answer:

Step-by-step explanation:

Are you certain you wrote the question accurately?—because none of the choices is correct.

rearrange 3x+y =-5 to solve for y:

y = -3x-5

substitute -3x-5 for y into the second equation:

12x + 3y = 13

12x + 3(-3x-5) = 13

12x - 9x - 15 = 13

3x = 28

x = 28/3

y = -3x-5 = -33

solution: (28/3, -33)

Find the slope and the y-intercept of the line
Vinvika [58]

The slope is basically the coefficient of x and that is 1 since 1x=x. To find the y-intercept, you need to subtitute x=0 into y=x+5 because x is at 0 when you are looking at the y-intercept.

y=0+5=5

So the slope is 1 and the y-intercept is 5.

How would you write y = 2x - 3 in function notation? *
nika2105 [10]

Answer:

f(x)=2x-3

Step-by-step explanation:

To write an equation in function notation change the y to an f(x). Then, if you plug something in for x also replace it in f(x). For example, if x=3 then the equation would be f(3)=2(3)-3.

How to divide an answer in simplest terms
Rufina [12.5K]

Answer:

Well to find simplest terms you have to find the GCF. (greatest common factor) for the numerator and the denominator

Step-by-step explanation:

So lets say you have 4/8 they both can be divided by 2. So that is what you do. Divide by two on the numerator and the denominator to get 1/2.

Also, if you have 3/5 you can't simplify it anymore because it is already in the lowest terms.

I hope that helped. If you have any questions just ask.
