Question

@mdillon1230 I need help with algebra

Answer 1

i completely suck at algerbra but throw it at me lol

Answer 2

Let x = one of two real numbers
and y - second of two real numbers
.
Since we have two unknowns, we'll need two equations.
.
From:"that have a sum of 8" we get equation 1:
x + y = 8
.
From:"product of 2" we get equation 2:
xy = 2
.
Solving equation 1 for y:
x + y = 8
y = 8-x
.
Plug the above into equation 2 and solve for x:
xy = 2
x(8-x) = 2
8x-x^2 = 2
0 = x^2 - 8x + 2
Since, we can't factor, we must use the quadratic equation.


x = {7.742, 0.258}
y = (0.258, 7.742)
.
Answer: the two numbers are 7.742 and 0.258

Answer 3

how's that.

Answer 4

lol i just needed the written expression not the solution and quadratic.

Answer 5

oh lol x + y = 8
y = 8-x

Answer 6

feel free to give medals xD

Answer 7

its incorrect

Answer 8

The sum of eight
8
and the product of two
8+2*
and a number x.
8+2*x

In traditionalform: 2x+8

Answer 9

4x

Answer 10

im sorry @shaleiah i said i suck at algebra now we know to tagg @robtobey
