Jamil hiked 7 miles. Hannah hiked

Mathematics
1 answer:
lidiya [134]3 years ago
6 0

Answer:

7 miles × 1

Step-by-step explanation:

If Jamil hiked 7 miles, and Hannah walked ONE times as far then Hannah walked the same distance

If Hannah were to walk 2 times then you double the amount Jamil hikes, but since Hannah only walked 1 times more, the answer stays the same so:

7 miles × 1 times as far = Hannah hiked 7 miles

If f(x) = 8 – 10x and g(x) = 5x + 4, what is the value of (fg)(–2)?
Vedmedyk [2.9K]
F(x) = 8 - 10x

g(x) = 5x + 4

Finding (fg)(-2).

First let us find fg(x),  this is the same as f(g(x))

f(g(x))

f(5x + 4)

Recall, f(x) = 8 - 10x, therefore f(5x + 4) would be such that anywhere we see x in the f(x), we replace it with 5x + 4

f(x) = 8 - 10x

f(5x +4) =  8 - 10(5x + 4)

             =  8 - 50x - 40

             = -50x + 8 - 40

             =  -50x - 32

f(g(x)) = fg(x) = -50x - 32

fg(-2) = -50*(-2) - 32 = 100 - 32 = 68

Therefore fg(-2) = 68

I hope this helped.

Express each equation in slope-intercept form. -2x+4y=68, 13x+4y=284
lara31 [8.8K]
To get the answer we have to tranform into y=ax+b form
-2x+4y=68          /+2x
4y=2x+68          /:4
y=\frac{1}{2} x+17  - its the result

13x+4y=284           /-13x
4y=-13x+284        /:4
y=- \frac{13}{4}+ 71
y=-3 \frac{1}{4}x+71 - its the result
