Answer:
y=7x -8
Step-by-step explanation:
I used desmos but you can also use an equation. I'm sure you're teacher taught you how.
Answer:
c) (6,0)
Step-by-step explanation:
The formula to find a slope is y=mx-b where m is the slope (to find the slope you find the change in y and the change in x) which in this case is -3. The change in y is -3 and the change in x is -1. If you put it on a graph the line is going down from left to right and it intersects the y-axis at 18 meaning if you keep sloping down in a straigt line it intersects the x-axis at (6,0).
In an equation the Left hand side must equal the right hand side
4(5y-8-2)=185-15
20y-32-8=170
20y=170+32+8
20y=210
Therefore y=10,5
When you substitute the 10,5 and solve it on the left and side it's equal to 170 which is the answer on the right hand side
Answer:
Step-by-step explanation:
The given polynomial function is
According to the Rational Roots Theorem, the ratio of all factors of the constant term expressed over the factors of the leading coefficient.
The potential rational roots are
Answer:
98
Step-by-step explanation:
So we have the expression:
And we want to evaluate it when x is 3 and y is 8.
So, substitute:
Multiply:
Add:
And we're done!
