Please Help, This Is For 8th Grade Math.

Answers

Answer 1

Answer:

(2,-2)

Step-by-step explanation:

The first step is to substitute y in the first equation with the right side of the second equation because they both equal to y.

-3x+4 = 4x-10

-3x-4x+4-4 = 4x-4x-10-4

-7x = -14

-7x/-7 = -14/-7

x = 2

Plugin 2 for x for either equation to solve for y, I'll be using the second equation, but either one is fine.

y = 4(2)-10

y = 8-10

y = -2

Plugin x = 2 and y = -2 into (x,y), and you get (2,-2)

Answer:

y = 3x - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x - 12 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes , then

y = 3x + c ← is the partial equation

To find c substitute (1, - 2 ) into the partial equation

- 2 = 3 + c ⇒ c = - 2 - 3 = - 5

y = 3x - 5 ← equation of parallel line

2-(3x+5)=5-2x

i have too answers but need the right one lol​

Answers

Answer:

x = -8

Step-by-step explanation:

2 - (3x + 5) = 5 - 2x

Subtract 2 from each side.

-(3x + 5) = 3 - 2x

Apply the negative sign in front of the parentheses.

-3x - 5 = 3 - 2x

Add 5 to both sides.

-3x = 8 - 2x

Add 2x to both sides.

-x = 8

We can't have a negative x value, so we'll need to multiply each side by -1.

x = -8

Hopefully, this helped and wasn't too confusing!

Answer:

Solution given;

2-(3x+5)=5-2x

2-3x-5=5-2x

-3-5=3x-2x

x=-8 is your answer

Answers

Answer:

Linear

Step-by-step explanation:

Linear it forms a straight line when it graphed. It also has a slope and a constant.

your answer is linear



A linear equation is an equation of a straight line, which means that the degree of a linear equation must be
0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1.

For kgP equals kg of person

Just use ratios to get the answers and solve for X.

100kgP/66kgW=150kgP/X

Does the equation represent a linear or nonlinear function?

y=x2+3

Answers

Answer:

Nonlinear function.

Step-by-step explanation:

If the x2 is supposed to mean x², then the function is quadratic, not linear.

Answer: Nonlinear function.

Step-by-step explanation:

the variables do not have powers more than 1,

variables do not occur in the denominator of a fraction.

different variables do not appear in the same term

In this case, there is a term in x2

so the function is not linear.

It is a parabola.
