What is the solution to the system of equations?y = –5x + 3

y = 1

(0.4, 1)
(0.8, 1)
(1, 0.4)
(1, 0.8)

Answers

If you would like to know the solution to the system of equations, you can do this using the following steps:

y = –5x + 3
y = 1
_______________
1 = –5x + 3
5x = 3 - 1
5x = 2 /5
x = 2/5 = 0.4

(x, y) = (0.4, 1)

The correct result would be (0.4, 1).

Solve the system using substitution. Show your work.
y=-4x+2
x-2y=23

Answers

Answer:

1. y = -4x + 2

Now, we can substitute this expression for y into the second equation:

2. x - 2y = 23

Substitute the value of y from equation 1 into equation 2:

x - 2(-4x + 2) = 23

Now, simplify and solve for x:

x + 8x - 4 = 23

Combine like terms:

9x - 4 = 23

Add 4 to both sides:

9x = 27

Divide by 9:

x = 3

Now that we have found the value of x, substitute it back into equation 1 to find y:

y = -4x + 2

y = -4(3) + 2

y = -12 + 2

y = -10

So, the solution to the system of equations is:

x = 3

y = -10

What is the value of x in the equation –x = 4 – 3x + 6?

Answers

remember you can do anything to an equaiton as long as you do it to both sides

-x=4-3x
add 3x both sides
3x-x=4+3x-3x
2x=4+0
2x=4
divide 2
2x/2=4/2
2/2x=2
1x=2
x=2

D. None of the above

Answers

Precipitation (inches): 9.4, 9.1, 9.8, 10.9, 9.2, 10.7, 9.1, 8.1, 9.1, 9.4

Arrange in ascending order:
8.1, 9.1, 9.1, 9.1, 9.2, 9.4, 9.4, 9.8, 10.7, 10.9

The outlier is 10.9

Mean = 9.48
Median = 9.3
Q1 = 9.1
Q3 = 9.8
