You have to factorize 100
100 | 2
50 | 2
25 | 5
5 | 5
1
So 100 = 2²*5²
Answer:
26. H
Step-by-step explanation:

Answer:
y = 5x + 10
Step-by-step explanation:
From the information given, we can derive the points (-2, 0) and (0, 10). Find the slope using the slope formula:
![m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B%5Ctext%7Brise%7D%7D%7B%5Ctext%7Brun%7D%7D%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
Plug in the points:
![m= \frac{10 - 0}{0 - (-2)}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B10%20-%200%7D%7B0%20-%20%28-2%29%7D)
Simplify:
![m= \frac{10}{2}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B10%7D%7B2%7D)
m = 5.
The equation in slope-intercept form is y = mx + b. We were already given the b value, or y-intercept as y = 10. Therefore:
y = 5x + 10 is the equation written in slope-intercept form.
Here you can subtract to find your answer.
200(initial amount)- 21(arcade) - 39(clothes)= money put in account
200 - 21 - 39
179- 39
He put 140 dollars into his account
Your answer is A
Hope this helps!
