Solve the system by substitution.
x= -5y - 6
5x – 3y = -2
What’s is the solution?

Answers

The value of x is -1 and value of y is -1.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equations are

x+5y=-6...(1)

5x – 3y = -2...(2)

Multiply equation 1 with 5

5x+25y=-30..(3)

Subtract equation 2 and equation 3

5x-3y-5x-25y=-2+30

-28y=28

Divide both sides by 28

y=-1

Now plug in y value in equation 1

x=5-6

x=-1

Hence, the value of x is -1 and value of y is -1.

determine if the point (4,7) is a solution to the system of equations shown below. Justify your yes/no answer.
y=2x-1 and y=1/2x+5

Answers

Answer:

The point (4,7) is a solution to the system of equations.

Please also check the attached graph.

Step-by-step explanation:

Given the system of equations

[tex]y=2x-1[/tex]

[tex]y=\frac{1}{2}x+5[/tex]

Let us solve the system of equations using the elimination method

[tex]\begin{bmatrix}y=2x-1\\ y=\frac{1}{2}x+5\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y-2x=-1\\ y-\frac{1}{2}x=5\end{bmatrix}[/tex]

subtracting the equations

[tex]y-\frac{1}{2}x=5[/tex]

[tex]-[/tex]

[tex]\underline{y-2x=-1}[/tex]

[tex]\frac{3}{2}x=6[/tex]

now solving [tex]\frac{3}{2}x=6[/tex] for x

[tex]\frac{3}{2}x=6[/tex]

Multiply both sides by 2

[tex]2\cdot \frac{3}{2}x=6\cdot \:2[/tex]

Simplify

[tex]3x=12[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}=\frac{12}{3}[/tex]

Simplify

[tex]x=4[/tex]

For [tex]y-2x=-1[/tex] plug in x = 4

[tex]y-2\cdot \:4=-1[/tex]

[tex]y-8=-1[/tex]

Add 8 to both sides

[tex]y-8+8=-1+8[/tex]

Simplify

[tex]y=7[/tex]

Therefore, the solution to the system of equations is:

(x, y) = (4, 7)

Hence, the point (4,7) is a solution to the system of equations.

Please also check the attached graph.

What is the value of x?

Answers

95 I think hope this helps

Answer:

Step-by-step explanation:

Step One

Find the supplement of both exterior angles. They both have angles that add with them to make 180 degrees.

x + 105 = 180 Subtract 105 from both sides

x = 180 - 105

x = 75

y + 148 = 180 Subtract 148 from both sides

y = 180 - 148

y = 32

Step Two

There are two ways to conclude the problem. You could find the value of the 3rd angle of the triangle, or you could notice that x is going to be the sum of the 2 angles you just found. These two angles are called the remote interior angle.

Method One

x = 32 + 75

x = 107

Method Two

32 + 75 + y = 180

107 + y = 180

y = 180 - 107

y = 73

The sum of x + 73 = 180

x = 180 - 73

x = 107

Emily deposited $5,000 into a savings account 6 years ago. The simple interest rate is 3%. How much money did Emily earn in interest? *

Answers

Answer:

$900

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 5000 × 0.03 × 6 = 900

I = $ 900.00

The simple interest accumulated

on a principal of $ 5,000.00

at a rate of 3% per year

for 6 years is $ 900.00.
