Answer: First Option

No solution

Step-by-step explanation:

We have the following system of linear equations

y = -2x + 1

4x + 2y = -2

-------------------------------------

To solve the system of equations using the substitution method, enter the first equation in the second equation as shown below.

4x + 2(-2x + 1) = -2

4x -4x + 2 = -2

0= -4

The variable x is eliminated and 0 is not equal to -4. So the system has no solution

Answer:

No solution

Step-by-step explanation:

The first equation is y=-2x+1

The second equation is 4x+2y=-2.

Put the first equation into the second one.

4x+2(-2x+1)=-2.

4x-4x+2=-2.

4x-4x=-2-2.

0=-4.

This is not TRUE.

Therefore the system has no solution

1. Regina. Phil and Joseph each wrote expressions to represent their hourly
aleksandrvk [35]

Answer:

15

Step-by-step explanation:

Regina: 6.5h

Phil: 3(2.5h+5)

When you plug in the number of hours, you get the weekly pay.  In order to get the same weekly pay, set the equations equal to each other.

6.5h=3(2.5h+5), This is an equation to find the number of hours it will take for them to get equal pay. Now, simplify.

6.5h=7.5h+15

-h=15

h=-15, -15 hours is your answer. You can't work negative hours though which means that Regina and Phil will never be able to make the same amount.

Phil has a higher rate and starting value, this means that Regina will never make the same amount working the same hours.

Find the area of the rectangle , i put a pic .
Gre4nikov [31]

Step-by-step explanation: Notice that the figure shown here is a rectangle so we can find its area by using the formula <em>length x width</em>.

Since the length is 3/7 in and the width is 2/8 in, we can plug this information into the formula to get (3/7)(2/8).

Now multiplying across the numerators and multiplying across the denominators we get 6/56 which can be reduced to 3/28 in².
