Subtract 6x from both sides 2y=-6x+12

Divide both sides by 2 y= -3 - 6

and now it's in slope intercept form where m=-3 and b= -6

Move 6x to the right side: 2y=12-6x
Divide both sides by 2: y=6-3x
m is the slope which in this case is -3
To see a graph plug y=6-3x into the website wolfram alpha!
Hope this helps!!

Evan was carrying forward a balance of $300 from the previous month. His annual interest rate is 30%. Use computation to determi

sattari [20]

Answer:

The interest charged for this month is $7.5

Step-by-step explanation:

Given:

Principal = $300

Interest = 30%

Time = 1 month

To Find:

The interest charged for this month = ?

Solution:

we know that the interest charged = $principal \times \text {Interest rate} \times time$

1 month can also be written as $\frac{1}{12}$

Substituting the values,

interest charged:

=> $300 \times 30% \times \frac{1}{12}$

=> $300 \times \frac{30}{100} \times \frac{1}{12}$

=> $300 \times \frac{3}{120}$

=> $\frac{900}{120}$

=> $\frac{30}{4}$

=> $\frac{15}{2}$

=> 7.5

Given that c = 2πr a. find c when π= 3.142 and r=50 b.find r when c=286 and π=31/7

Aleks04 [339]

Step-by-step explanation:

a.c=2πr

c=2x3.142x50

c=100x3.142

c=0.03142

b.c=2πr

286=2x31/7xr

286=62r/7

286x7=62r

2002=62r

2002/62=r

32.3=r

r=32.3
