I figured out the answer was 17.5 but my strategy was weird and I confused myself trying to type it on here but I checked my answers

13 + [128 + (-24 - 5b)/2)]/3 - 45 = 0
(52 - 5b/2)/3 = 32
52/3 - 5b/6 = 32
14.67(6) = -5b
b = 88/-b
b= -17.6

What is hs the answer to this question?<br><br> Y= 5x+5<br> Y - x=5

ANEK [815]

Y = 5x + 5
y - x = 5

You can use substitution to solve this system. Use y's expression (5x + 5) for y in the second equation to solve for x:

y - x = 5
5x + 5 + x = 5
6x + 5 = 5
6x = 0
x = 0

Substitute your value for x into one of the original equations to y:

y = 5x + 5
y = 5(0) + 5
y = 5

Finally, substitute both values into both original equations to check your work:

5 = 5(0) + 5 --> 5 = 5 <--True
5 - 0 = 5 --> 5 = 5 <--True

Answer:
x = 0
y = 5

Solve 4X^2+7 = 8X +4 by using the quadratic formula

Sergio [31]

Answer:

(1.5,0)

(.5,0)

Step-by-step explanation:

Quadratic formula below

We first need to move everything to one side of the equation

4x²-8x+3=0

Then plug everything in

(8±√(-8²-4*4*3))/(2*4)

(8±√16)/8

To calculate the ± we need to do when where it's adding and then negative

we have

(8+4)/8=3/2

and hten

(8-4)/8=1/2
