Answer:

0.07 or 7%

Step-by-step explanation:

I = Prt

630 = (1000)(9)r

630 = 9000r

r = 0.07

Step-by-step explanation:

Simple interest (SI) = $ 630

Time (T) = 9 years

Principal (P) = $ 1000

Rate (R) = ?

We know

si  =  \frac{ptr}{100}  \\630  = \frac{1000 \times 9 \times r}{100}  \\ 630 = 90r \\  r \:  =  \frac{630}{90}   \\  = 7\%

Therefore the rate of interest is 7%.

Hope it will help :)❤

Write an equation in slope intercept form thag passes through (4,-4) and is parallel to 3+4x=2y-9
uysha [10]

The original line is

4x - 2y = -12

The parallel lines will all be

4x - 2y = constant

and the constant is given by the point directly:

4x - 2y = 4(4) - 2(-4) = 24

2y = 4x - 24

y = 2x - 12

Answer: y = 2x - 12

chubhunter [2.5K]

The answer is D. -2x+5.

If we simplify the left side of the equation first given, we come to the expression -2x-10.

If we solve for D., we get the same results. Thus, because an equation with all the same variable terms and constants have infinite solutions, the answer is D.

Hope this helps!
