Answer:

y = 4x + 1

Step-by-step explanation:

2 points on chart: (1, 5) and (2, 9)

Slope:

m=(y2-y1)/(x2-x1)

m=(9-5)/(2-1)

m=(4)/1

m = 4

Slope-intercept:

y - y1 = m(x - x1)

y - 5 = 4(x - 1)

y - 5 = 4x - 4

y = 4x + 1

BRAINLEIST!!!! You have a credit card with a balance of $754.43 at a 13.6% APR. You have $300.00 available each month to save or

Alex

We are given
P = $754.43
r = 13.6% annual

for a.
A = 150
for b.
A = 300

First, change the interest into effective monthly
i = (1 + 0.136/12)^12 - 1
Solve for i

Next, use the general formula
A = P i ( 1 + i)^n / (1 + 1)^n - 1
Subsitute P, i, and A for a and b.
Then, solve for n for a and b.

Isn’t it just 5? Why would it say check all that apply

Answer: $25^\frac{1}{2}$

Step-by-step explanation:

25 = 5*5 or -5 * -5

yes, that is correct. However, you forgot another property of roots. Roots are simply exponential fractions.

$\sqrt[n]{x^m}=x^\frac{m}{n}$

Therefore, $\sqrt{25}$ can also be rewritten as: $25^\frac{1}{2}$ . Notice that it cannot be -25 because that would be a negative square root which will give us an imaginary number.
