Answer: y=x+2 or x-10
Step-by-step explanation:
Y=x2-8x-20
Quadratic equation
Variables of -20 that will give -8 are
-10 &+2
Substitute into the equation
Y=x2-10x+2x-20
Y=x(x-10)+2(x-10)
Y=(x+2)(x-10)
The two equations are
Y=x+2 or
Y=x-10
Answer:
y = -1/2x + 2
sum means add so add
pls give me brainliest im almost lvled up
see photo for detailed analysis
First the equation would look like this:
7n = 5n - 3
7n - 5n = 5n - 5n - 3 -Subtract 5n from both sides. Which gives you...
2n = -3
2n/2 = -3/2 -Divide both sides by 2
n = -1.5
Hope this helps!
