Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

n = 5m

n = 2/3m - 13

Step 2: Solve for m

Substitution

Substitute in n:                                 5m = 2/3m - 13Subtract 2/3m on both sides:          13/3m = -13Divide 11/3 on both sides:                m = -3

Step 3: Solve for n

Define equation:                    n = 5mSubstitute in m:                      n = 5(-3)Multiply:                                  n = -15
Answer 2

Answer:

Step-by-step explanation:

5m = 2/3m - 13

15m = 2m - 39

13m = -39

m = -3

n = 5(-3)

n = -15

(-3, -15)

?

Answers

It’s A- 19/12

Substitute y=0

Move the Variable to the left

Divide both sides by -12

Then the answer is 19/12
The slope would be 12. In that equation, 12= m. M means the same thing as slope.

Mr. Parker wants to rent a cargo van for a day. It will cost the daily fee of $50 plus $0.35 per mile driven. Let m = the number of miles Mr. Parker drives for the day. Write an algebraic expression that shows the amount he will pay for the van. * 10 points \

Answers

Answer:

y=0.35m+50

Step-by-step explanation:

Step one:

given data

the daily fee= $50

cost per mile driven =$0.35

Let m = the number of miles

let y be the total cost

Step two

Required

DilationsDiameter: d = 2rVolume of a Cone: [tex]V= \frac{1}{3} \pi r^2h[/tex]

Step-by-step explanation:

Step 1: Define

Height h = 8

Diameter d = 6

Base b = 5.4 (not needed in calculations)

Step 2: Find radius r

Substitute:                    6 = 2rIsolate r:                        3 = rRewrite:                         r = 3

Step 3: Find V of Normal Dimensions

Substitute:                    [tex]V= \frac{1}{3} \pi (3)^2(8)[/tex]Exponents:                   [tex]V= \frac{1}{3} \pi (9)(8)[/tex]Multiply:                        [tex]V= 24 \pi[/tex]Evaluate:                      [tex]V \approx 75.3982[/tex]

Step 4: Find Dilations

Scale Factor: 2

Define radius:                    r = 3Dilate:                                 r' = 3(2)Multiply:                              r' = 6Define height:                    h = 8Dilate:                                 h' = 8(2)Multiply:                              h' = 16

Step 5: Find V of Dilated Dimensions

Substitute:                     [tex]V= \frac{1}{3} \pi (6)^2(16)[/tex]Exponents:                    [tex]V= \frac{1}{3} \pi (36)(16)[/tex]Multiply:                         [tex]V= 192 \pi[/tex]Evaluate:                       [tex]V \approx 603.186[/tex]

In the slope-intercept form, which variable
represents the slope/measure of change?

Answers

Step-by-step explanation:

Hey there!

We know that the slope intercept is; y = mx+b.

Where "m" represents the slope. And "b" represents the y-intercept.

Example:

If the question is as; y = 3x +8

Then your slope of the slope intercept form is "3" where as "8" is y-intercept.

So, the variable"m" represents the slope.

Hope it helps...
