Answer:

x=8

y=13

Step-by-step explanation:

This shape is a parallelogram, and in a parallelogram, the diagonals bisect eachother. So then, you can write to equations:

2x=y+3

x+5=y

This is equal to:

2x-y=3

x-y=-5

Then, you can subtract the two equations, making it:

2x-y=3

-x+y=5

Then the result will be:

x=8

Now that we know what x is, you can find y by plugging it in to either equation.

8-y=-5

-y=-13

y=13

Hope this was helpful!

Y= x + 4
Mice21 [21]

Answer:

Step-by-step explanation:

Simplifying

2x + 4y = 13

Solving

2x + 4y = 13

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4y' to each side of the equation.

2x + 4y + -4y = 13 + -4y

Combine like terms: 4y + -4y = 0

2x + 0 = 13 + -4y

2x = 13 + -4y

Divide each side by '2'.

x = 6.5 + -2y

Simplifying

x = 6.5 + -2y

(Hope this helped!)

If f(x) =1/2x + 7 and g (x) = 6x -8 find (f•g)(5)
Lorico [155]

Answer:

  (f•g)(5)=   \frac{309}{44}

Step-by-step explanation:

f(x) =1/2x + 7

g (x) = 6x -8

f(g(5))

f(22)=\frac{1}{2x}+7

      = \frac{1}{44}+7

      =\frac{309}{44}

Joe drives 20 mi-in 1/2 h. how Long Will it take him to derive 50 mi?
tiny-mole [99]
An hour and 15 minutes.  Since Joe is driving 20 miles per 1/2 hour that means he is driving 40 miles every hour. We still have 10 miles left and since 20 divided by 2 is ten you would simply cut the time it takes him to drive 20 miles in half making 15 minutes. Then you add the time it takes to drive 40 miles and 10 miles and that's how you get an hour and 15 minutes. Hope this made sense!
