Is (1,-3) is a solution of the equation 8p-2q=14?
PSYCHO15rus [73]

Answer: YES

<u>Step-by-step explanation:</u>

  8p - 2q = 14

8(1) - 2(-3) = 14

8   -    -6   = 14

 8    +   6  = 14

       14      = 14

1.) You are one of five people who have been hired to mow the lawn at the local college. Each week, the dimensions of the plot y
iren [92.7K]

Answer:

1a)  Length = 7x + 3  & Width = 4x - 2

1b)  Area = 28x^2 -2x -6

1c)  Area = 2774 sq. m

2.  (x-4)(y+7)

Step-by-step explanation:

1a)

The length given as words is "3 more than 7 times x"

The width given as words is "4 times x minus 2"

The expression for length would be  7x + 3

The expression for width would be 4x - 2

1b)

The area is length * width

Since we already know the algebraic expressions for length and width from part (a) above, we use the formula:

Area = (7x+3)(4x-2) = 28x^2 -14x + 12x - 6 = 28x^2 -2x -6

Area = 28x^2 -2x -6

1c)

Given x = 10, we put this into the area expression we found in (b) above.Let's see:

28x^2 -2x -6\\=28(10)^2 -2(10) -6\\=2774

Area = 2774 sq. m

2.

We can group the first two terms and next two terms and write up:

xy-4y+7x-28\\(xy-4y)+(7x-28)\\y(x-4)+7(x-4)\\(x-4)(y+7)

That's the factored form.

What is the solution to the system of equations?
xxTIMURxx [149]

As with a system of equations, call them A and B in order to keep them straight.

A: x + y = 7

B: x = y + 3

Because in B we have x on one on one side and not x on the other, substitution is the way to go. Substitute equation B into equation A.

x + y = 7 Equation A

y + 3 + y = 7 Putting B into A

2y + 3 = 7 Collect like terms

2y = 4 Subtract 3 on both sides

y = 2 divide both sides by 2

With y = 2 we can substitute that back into an original equation. Choose B.

x = y + 3

x = 2 + 3

x = 5


Thus x = 5 and y = 2, or (5, 2) is the solution of this system.
