Rewrite 80 as its prime factor
Square root (2x2)x(2x2)x5

Group the same prime factors into pairs.
(2x2)x(2x2)x5

Rewrite each pair in exponent form.
2(2) x 2(2) x 5

Use this rule: square root of x(2) = x.

(2x2) square 5

Simplify 4 square 5

Decimal form: 8.944272

Solve the system of equations by using substitution. Give your final answer in the form of an ordered pair.
Goshia [24]
5x -2y = 26. We know that x = y + 4. Substitute the value of x in and you get 5y + 20 - 2y = 26 If yous simplify this you get 3y + 20 = 26
Take away 20 from both sides and you end up with 3y = 6
Now did use both sides by 3

You end up with y = 2
Now to find x you just simplify the value of y into x = y + 4. You end up with x = 2 + 4. Now you know that y = 2 and. X = 6

What is the answer to Ax - c = b
Korvikt [17]
Depends on what you are talking about, what is A,x,c and b.
If A is an invertible matrix and x,c,b are vectors of correct dimensions you get
Ax=b+c
x=A^(-1)(b+c)
if x is a variable and A,c,b are constants you get
Ax=b+c
x=(b+c)/A
