Answer:
C.Tammy’s estimate is right, but the actual product should be 24.78.
Step-by-step explanation:
i took the assessment! thank you for your attention and i hope i helped!!
Solve for y by setting one equation =to X after that you can substitute the equation into the other one let's set the first one in X= FORM
X-7y=10
-2x+14y=-20
Add 7y to both sides of the first equation to let x stand alone
X=7y+10
Now you can substitute x on the second equation
-2 (7y+10)+14y=-20
Distribute
-14y-20+14y=-20
Add and simplify
Us cancel out =0
-20=-20
0=0
They are the same equations you can also divide the second equation by -2 which would make it look like this
X-7y=10
-2 (x-7y=10)
Let me know if I have answered your question
Answer: 207/4 or -51.75
Step-by-step explanation:
Answer:
1. x= - 20/13
2. 7x-21
Step-by-step explanation:
The formula for slope is
m= (y₂-y₁)/(x₂-x₁)
you can plug in the points that you are given to find the slope
m= (-1-2)/(2-(-4)
m= -3/6
the slope is -3/6 which reduced to -1/2
so the answer would be
c) -1/2
hope this helped!
