Answer:
Step-by-step explanation:
I’m assuming that the equation is to be written in slope intercept form (y=mx+b), so for this, you want to find the slope and y-intercept. To find the slope, use the equation in picture 1.
0 - 5 = -5
1 - 5 = -4
-5 / -4 = 1.25
So m, or the slope, is equal to 1.25.
To find the y-intercept, make a table like the second picture. Choose one of the ordered pairs as the given. I used 1,0.
0,?
1,0
Now find the change in x, which in this case, is 1. Then set up something like picture three.
1.25/1 = ?/1
?=1.25
Now backtrack to get:
0, -1.25
1, 0
Now we know what is y when x is 0, we know the y intercept and can make the equation:
y = 1.25x - 1.25
Answer:
Step-by-step explanation:
According to the first expression:
2(10-k): where,
2:shows the double amount of money which ELI has
10:shows the amount of money which ELI had at the starting.
k:shows the amount of money which is lost.
10-k:shows the amount of money which ELI has after losing some amount.
According to the second expression:
20-2k where,
20:shows the twice of initial amount.
k: is the amount of money which is lost
2k:s hows the twice of amount which is lost
20-2k: shows the amount of money which is left with ELI after his mom gave him some money....

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = ∛(x - 4)
f(-121) is x = -121
f(31) is x = 31
<u>Step 2: Evaluate</u>
f(-121)
- Substitute in <em>x</em>: f(-121) = ∛(-121 - 4)
- [Radical] Subtract: f(-121) = ∛(-125)
- [Radical] Evaluate: f(-121) = -5
f(31)
- Substitute in <em>x</em>: f(31) = ∛(31 - 4)
- [Radical] Subtract: f(31) = ∛27
- [Radical] Evaluate: f(31) = 3
