Jill rented (B) 2 movies that month.

<h3>What is an equation?</h3>

An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
The word equation and its cognates in other languages may have subtly different meanings; for example, in French, an équation is defined as containing one or more variables, whereas in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign.

To find how many movies did Jill rent online that month:

The equation for the monthly bill when m number of movies are rented per month = 9.80 +1.5m.
Given, 9.80 + 1.5m=12.80
1.5m = 3
m = 2

Therefore, Jill rented (B) 2 movies that month.

Your bike was originally purchased for $1,200. It loses about 8% of its original value each year. Write an equation to represent

Arlecino [84]

Answer:

y= 1200(0.92)^x

Step-by-step explanation:

Given data

Cost price= $1200

Rate of decrease= 8%

Let the time be x

The expression that describes an exponential function is

y= ab^x

for decrease b= 1-r

y= 1200(1-0.08)^x

y= 1200(0.92)^x

Hence the expression is

y= 1200(0.92)^x

Graph a line with a slope of 1/4 that contains the point (6, 3).

Semenov [28]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a line in point slope form is

$y-y1=m(x-x1)$

we have

$(x_1,y_1)=(6,3)$

$m=\frac{1}{4}$

substitute

$y-3=\frac{1}{4}(x-6)$

The easiest way to graph a line is to calculate the intercepts

The<u><em> x-intercept </em></u>is the value of x when the value of y is equal to zero

For y=0

$0-3=\frac{1}{4}(x-6)$

$-12=(x-6)$

$x=-12+6=-6$

The x-intercept is the point (-6,0)

The <u><em>y-intercept</em></u> is the value of y when the value of x is equal to zero

For x=0

$y-3=\frac{1}{4}(0-6)$

$y-3=-\frac{3}{2}$

$y=-\frac{3}{2}+3$

$y=1.5$

The y-intercept is the point (0,1.5)

Plot the intercepts and join the points to graph the line

(-6,0) and (0,1.5)

-6x-6y =18 6x-3y=27 its supposed to be solving systems by elimination by adding or subracting, im really confused.

Lera25 [3.4K]

Answer:

y = -5

x = 2

Step-by-step explanation:

The computation is show below:

Given that

-6x - 6y = 18

6x - 3y = 27

Now if we solved both equation so

-9y = 45

y = -5

And, x is

-6x - 6(-5) = 18

-6x + 30 = 18

-6x = 18 - 30

-6x = -12

x = 2

Find the circumference of each circle. Use 3.14 or 22/7 for T. Round to the

Ludmilka [50]

Answer:

4. Circumference = diameter × π

8× 3. 14= 25. 12 ~25. 1

5. 13×3. 14= 40. 82 ~40. 8

6. Diameter= radius ×2

3. 5×2=7

Diameter = 7

7× 3. 14= 21. 98 ~22
