1626 divided by 1 very simple just put that :D
The first equation, make the y as the subject. y = 3 + 5x, then substitute y in the second equation and you will get the value of x. then, substitute the x in the first equation (y = 3 + 5x)
1. The function of this graph is f(x) = 0.5x + -2
Plug (-2) into the x variables so it looks like:
f(-2) = 0.5 (-2) + -2
Then solve.
Answer: f(-2) = -3
**I'm not as sure about this one, so I might be wrong
2.
For #8, the y-intercept is 4 (you're right) and it represents the initial distance before she started hiking (D)
I tried to figure #9 out, but I couldn't find the answer. I came across a website that might help though: https://sciencing.com/determine-practical-domain-range-10052000.html
**I can't see #s 6 or 7
Answer:
k=−5
Step-by-step explanation:
−3(k+7)−5k+4=23
(−3)(k)+(−3)(7)+−5k+4=23(Distribute)
−3k+−21+−5k+4=23
(−3k+−5k)+(−21+4)=23(Combine Like Terms)
−8k+−17=23
−8k−17=23
Step 2: Add 17 to both sides.
−8k−17+17=23+17
−8k=40
Step 3: Divide both sides by -8.
−8k
−8
=
40
