Step One

Find the slope

y2 = 79; y1 = -20; x2 = 9; x1 = -2

Formula

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

Solve

m = (79 - - 20) / (9 - - 2)

m = 99/11

m = 9

Step Two

Set up the equation. Use (-2,-20) as the point.

(y - -20) = 9(x - - 2)

y + 20 = 9(x + 2 )

What does “x” represent

galina1969 [7]

The answer is 4 as 4x4 is 16 (squared means the number multiplied by itself) and

16+16+9=41

Therefore the answer is x=4

#1
$sin(51^o)= \frac{y}{12} \ \ \to \ \ y=12*sin(51^o)=12* 0.7771 \approx 9.33$

#2
$\theta=arccos( \frac{5^2+13^2-12^2}{2*5*13}) = arccos( \frac{25+169-144}{130})=arccos( \frac{50 }{130})= \\ \\ arccos(0.3846) \approx67.4^o$

#3
$tan(13^o)= \frac{x}{24} \ \ \to \ \ x=24*tan(13^o)=24* 0.2309 \approx 5.54$

#4
$sin(20^o)= \frac{10}{x} \ \ \to \ \ x= \frac{10}{sin(20^o)} = \frac{10}{0.342} \approx 29.24$

You borrow $30,000 to buy a new car. The simple interest

bagirrra123 [75]

Answer:

I think you have a typo in the interest rate. If you want to calculate the interest on $30000 at 2% interest per year after 5 years, the answer is $3,000. If you want to calculate the interest on $30000 at 5% interest per year after 5 years, the answer is $7500.

Step-by-step explanation:

I think you have a typo in the interest rate. If you want to calculate the interest on $30000 at 2% interest per year after 5 years, this is the correct answer:

The formula we'll use for this is the simple interest formula, or:

P= I × r × t

Where...

P equals the principal amount, which is $30000.00.

r equals interest rate, which in this case is 2% per year, or in decimal form, 2/100=0.02.

t equals time involved, which would be 5 years.

To find the simple interest, we multiply 30000 × 0.02 × 5 to get that the interest is: $3000.00

Now, if you want to calculate the interest on $30000 at 5% interest per year after 5 years, this is the correct answer:

The formula we'll use for this is the simple interest formula, or:

P= I × r × t

Where...

P equals the principal amount, which is $30000.00.

r equals interest rate, which in this case is 5% per year, or in decimal form, 5/100=0.05.

t equals time involved, which would be 5 years.

To find the simple interest, we multiply 30000 × 0.05 × 5 to get that the interest is $7500.00.

hope this helped! will you pls give a "thanks" and/or leave a brainllest since I had to do two different equations? :)

For 6z=126, Chris wrote that z=756. Explain what Mike’s mistake was. Then tell the correct answer.

Anarel [89]

Step-by-step explanation:

6z=126

z = 126 ÷ 6 = 21

Chris's

z = 756

6z= 126

z = 126 × 6 = 756

correct answer = 21

the number 6 is being multiplied with z.So if the number 6 is going to the right side it will divide the number on the right side.

but for chris he multiplied the number on the right side with 6.So that is the mistake.

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit

Volgvan

Answer:

See below

Step-by-step explanation:

Given equation:

2x + 3y = 1470

Change to slope-intercept form:

2x + 3y = 1470, isolate y
3y = -2x + 1470, divide all terms by 3
y = -2/3x + 490

The slope is -2/3 and y-intercept is 490

Functional notation, change y to f(x)

f(x) = -2/3x + 490

To graph the line, plot the intercepts and connect with the line.

If the total is $1593 for the next month, the function would be:

2x + 3y = 1593

Changing to slope-intercept:

y = -2/3x + 531

The slopes are same, therefore the lines are parallel.

The difference is the y-intercept, it is greater in the next month.

The graphs are attached, with intercepts shown.
