Evaluate 5(x + y)2 when x = 3 and y = 9

Mathematics
1 answer:
irakobra [83]3 years ago
4 0

Hey there!

Answer:\boxed{120}

Explanation:

5(x+y)2 when x = 3 and y = 9

Let's first move to x and y.

x=3\\y=9\\3+9=12

Now multiply 5 by x and y(3+9).

5*12(\text{x and y combined)}=60

Now we have the number 2 left, so we have to multiply 60 by 2.

60*2=120

\boxed{120}\text{ is your final answer.}

Hope this helps!

How do I solve 5x - 4x^2
Sever21 [200]

Answer:

If you are asking,

5x - 4x^2=0

x(5-4x)=0

Either,

x=0

or,

5-4x=0

x=5/4

If factor,

5x - 4x^2

x(5-4x)

If difference,

5x - 4x^2

The same as they are not like terms.

Find the slope and y-intercept of the graph of 4x-3=36
Oxana [17]

Answer: Slope is undefined or aka infinity, and there is no y-intercept

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

Using Slope-Intercept Form to find the slope and the y-intercept.

First, lets change 4x-3=36 into y=mx+b. When you change it into this form you'll see that it can't go into intercept form because x=39/4 and is a vertical line so the slope is undefined or aka infinity, and there is no y-intercept.

Hope this helps! Have a nice day! ❤
