Hello Robyn,

Two equations given are 

2x - 6y = -10 -------------->equation 1

4x = 10 + 6y -------------->equation 2

We'll solve this problem using the elimination method.

Solve equation 2

4x = 10 + 6y (given)

-6y        -6y  (subtract 6y from both sides)

_______________

4x - 6y = 10 ------------------>new equation 2

Multiply equation 1 by -1 on both sides you'll get

-1(2x - 6y) = -1 (-10)

-2x + 6y = 10 -------------------> new equation 1

Add new equation 1 and new equation 2 to eliminate the y term you'll get

-2x + 6y = 10

4x - 6y = 10

_______________

2x = 20

(2x)/2 = 20/2 (divide both sides by 2)

x = 10 (answer)

Now, substitute the value of x in equation 1

2x - 6y = -10 (given)

2(10) - 6y = -10 (since, x = 10)

20 - 6y = -10

-20          -20   (subtract 20 from both sides)

_________________

-6y = -30 

(-6y)/-6 = -30/-6 (divide by -6 on both sides)

y = 5 (answer)

Good luck

Hello Jessica,

Use FOIL method to multiply

(m² - 5)(2m² + 3)

m²(2m² + 3) - 5(2m² + 3)

Now, distribute, combine like terms and solve you'll get your answers. I hope it helps you. If you need further assistance you can ask.

Hello Jessica,

Multiply 6.32 and 9.5

Multiply 10^-12 and 10^-5using exponent rule (a^m * aⁿ = a^m+n)

Combine your answer. If you need further help you can ask. Myself or any other tutor will help you.

Hello Connor,

The constant term of this polynomial is 10, with factors 1, 2, 5, and 10.

The leading coefficient is 2, with factors 1 and 2.

Then the Rational roots yields the following possible solutions:

±(factors of 10)/(factors of 2)

= ±(1, 2, 5, 10)/(1,2)

= ±1/1, ±1/2, ±2/1, ±5/1, ±5/2, ±10/1

= ±1, ±1/2, ±2, ±5, ±5/2, ±10 (answers)

Hope this helps.

Hello Jamal,

Given:   Width (W) = 8 inches

             Perimeter (P) = 42 inches

What to find : Length

Formula for perimeter of rectangle is

P = 2L + 2W

Plug in the values of P and W in the formula and solve for L. Try it out, if you still need help i'll be glad to help you.
