What is the solution of the linear system of equations? <br><br><br> y=2x-3<br> y=2x+5
Akimi4 [234]

Hi Brainiac


y=2x-3

y= 2x+5


Ok we need to solve y=2x-3 for y

Now substitute 2x-3 for y in y=2x+5

y=2x+5

2x-3=2x+5

Add -2x

2x-3-2x=2x+5-2x

-3=5

Add 3

-3+3=5+3

0=8

What is the length of the diagonal of a rectangle that is 12 inches long and 6 inches wide?​
lakkis [162]
To find the diagonal of the rectangle we have to use Pythagorean theorem!

Pythagorean theorem is used to find the length of a missing angle such as the hypotenuse or the sides a and b.

Steps to solve:

1. 12 in is the length or the base of the right triangle, and 6 in is the wide or the side a.
2. Now use the formula: a^2+b^2=c^2, and plug in the numbers!
3. 6^2+12^2=c^2, now just solve the squared numbers.
4. 36+144=c^2
5. 180=c^2
6. Find the square root of 180.

And that is you answer!

Use the compound amount formula:

A = P*(1+r/n)^(nt)

Here,

A = $3500*(1+0.0375/12)^(12*12) =  $5485.24
