Answer:
-22
Step-by-step explanation:
-3•f(-8)+7•g(2)=
The value of f(x) at x=-8 is
f(-8) = -2
The value of g(x) at x=2 is
g(2) = -4
Substituting these values into the equations
-3 * -2 +7*-4
6 -28
-22
Answer:
6.75 or 6 3/4
Step-by-step explanation:
First take the whole number and multiply that by 3.
2*3=6
Now, take the fraction and multiply that times 3.
1/4 as a decimal is 0.25. You can ignore the decimal point right now, but you have to remember it is there later.
So, whithout the decimal point, 25*3= 75.
Now, you add the decimal. The 75 is now 0.75, with the decimal.
Add the whole number and the decimal, and you have your answer!
6+0.75=6.75. As a fraction this is 6 3/4
