Lynna [10]3 years ago

8 0

Answer:

Step-by-step explanation:

1. Input the variables into the expression. It should look like 3/7*14+5/8*8. 3/7 and 5/8 are fractions.

2. Reduce 7 and 14 with their greatest common factor, 7. This should simplify the expression to 3*2+5/8*8.

3. Reduce the two 8's with their greatest common factor, 8. This should simplify the expression to 3*2+5.

4. Multiply 3 and 2. This should give you, 6.

5. Add 6 and 5. The final answer is 11.

Suppose that f(x)=8x+1. Complete parts (a) through (f).

olchik [2.2K]

F(x) = 8x + 1
a) The slope is the number on the x which is 8
b) y-intercept is added (or subtracted) to the x which is 1
c) f(0) = 8(0) + 1 = 1
d) 9 = 8x + 1
8 = 8x
x = 1 - solution
(1, 9) - ordered pair
e)
-7 <= 8x + 1
-8 <= 8x
-1 <= x
{x | x => -1}

I'll let you graph f(x)
