Answer:

The correct answer would be C) {28}

Step-by-step explanation:

Step 1, Cross multiply

7/p x 8/2

= 56= p x 2

Step 2: Switch the sides

p x 2 = 56

Step 3: Divide both sides by 2

( remember that we cross multiplied.)

p x 2/2 = 56/2

Step 4: Simplify

p = 28

So that answer would be C. p = 28

When Megan solved this system using the elimination method , she added the equations together and got the equation 4y = 16. Then

weqwewe [10]

Answer:

Megan added the equations together but she subtract 4 instead of addition of 4. The correct solution is (1,6).

Step-by-step explanation:

The given equations are

$2x+3y=20$ ...(1)

$-2x+y=4$ .... (2)

Add both equations to eliminate x.

$2x+3y-2x+y=20+4$

$4y=24$

Megan make a mistake in this step. She added the equations together but she subtract 4 instead of addition of 4.

Divide both sides by 4.

$y=6$

Put this value in equation (1).

$2x+3(6)=20$

$2x+18=20$

$2x=2$

Divide both sides by 2.

$x=1$

Therefore the correct solution is (1,6).

Find the vertex of this equation! NEED THIS ASAP!

enyata [817]

Answer:

(1,-4)

Step-by-step explanation:

x = -b/2a

a = 2

b = -4

x = 4/4

x = 1

Then substitute x = 1 into the equation to find y

y = 2(1)^2 - 4(1) - 2

y = -4

So, (1,-4)
