If f(x)=7(x-1)+8f(x)=7(x−1)+8 , what is the value of f(1)f(1) ?
natita [175]

Answer:

8

Step-by-step explanation:

All you have to do is plug in 1 for the x value, which leaves you with the equation 7(1-1) + 8, then you simplify it to be 7(0) + 8

7 times 0 is 0, so you are left with 8 as your answer

Solve the equation for y. Identify the slope and y-intercept then graph the equation.
viva [34]

Answer:

y = -3    m = -1     b = 3

Step-by-step explanation:

-3y=3x-9

To isolate the y variable, divide both sides by -3.

y = -1x + 3

y = -3

m = -1

How do i solve this
natima [27]

I think you are suppose to get "k" by itself, so you first multiply 2/5 to (k - 2)

-8 ≤ 2/5 (k - 2)

-8 ≤ 2/5k - 4/5

Next you add 4/5 on both sides

-8 + 4/5 ≤ 2/5k

Then you make the denominators the same in order to add them

-40/5 + 4/5 ≤ 2/5k

-36/5 ≤ 2/5k

Finally you multiply each side by 5/2 to get "k" by itself

-18 ≤ k
