4 0

Answer:

x=6, x=-5

Step-by-step explanation:

Factoring this quadratic gets you (x-6)(x+5)=0, for this to be possible, either x-6 or x+5 has to be zero, so therefor x is 6, or x is -5

-3|x|+2x-1 if x=-5<br> i need help with this or else i will not get my computer
DaniilM [7]

Answer:

-26

Step-by-step explanation:

Hello There!

For this problem all we have to do is plug in -5 into x and calculate the value

so..

-3|-5|+2(-5)-1

so first things first | | means absolute value

The absolute values of -5 is 5 so the equation would be

-3(5) + 2(-5) - 1

-3*5=-15

2*-5=-10

-15-10=-25

-25-1=-26

so the answer would be -26

Y=3x-7y=3x−7 Complete the missing value in the solution to the equation. (1,_) PLEASE QUICK
kkurt [141]

Answer:

-4

Step-by-step explanation:

The two equations you have are:

y = 3x - 7

x = 1 (this comes from the x value being 1)

To solve for y, use the substitution property of equality to replace x in the equation:

where x = 1,

y = 3(1) - 7

y = -4
