Use the elimination method to solve this system.
leva [86]

Answer:

The solution for this system is: x = -1, y = 1

Step-by-step explanation:

The problem states that we have to solve this system by the elimination method

In the elimination method, we transform the system in such a way that one variable can cancel each other. With this, we find the result of the other variable. Then, we can replace the variable we found in any of the equations, and we have the value of the variable that we had initially canceled.

In this problem, we have the following system:

1) -6x + 5y = 1

2) 6x + 4y = -10

If we add equations 1) and 2), the variable x is going to be eliminated

1) + 2)

-6x + 6x + 5y + 4y = 1 - 10

9y = -9

y = \frac{-9}{9}

y = -1

Now, we can replace the value of y in any of the equations, to find x:

I will replace in equation 2)

6x + 4y = -10

6x + 4(-1) = -10

6x = -6

x = \frac{-6}{6}

x = -1

The solution for this system is: x = -1, y = 1

Letters a, b, c, and d are angle measures.
DerKrebs [107]
D
b equals to 75 because they are diagonal, and the one diagonal to a equals 105 so that a and b form a line.
In order to prove f||g, we need to prove c=b, so c equals 75, d equals 105

Use point-slope form − 1 = ( − 1) to find the equation of the line that passes through the point (−3,5) and has slope = −2 . Wri
Tom [10]

Answer:

y - 5 = -2(x + 3)

Step-by-step explanation:

When you write an equation in point-slope form, you only need two things: a point and a slope.

Given:

point: (-3, 5)

slope (m): -2

The standard point-slope equation is

y - y₁ = m(x - x₁)

Plug in what you know.

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

Simplify.

y - 5 = -2(x + 3)

This is your equation.

For what value of x must ABCD be a parallelogram ?
Pavlova-9 [17]

Answer:

x = 4

Step-by-step explanation:

as it is parallelogram opposite sides are equal

so14x -7= 10x-9

14x-7+9=10x

14x -16 = 10x

14x -10x = 16

4x =16

x = 16/4

x = 4

also u can put x = 4 in both expressions and u will get answer of both 49
