Which graph shows a line with a slope of 2 and a y-intercept of 0?

Answers

Answer:

Its C

Can I please get a Brainlist please thx.

Step-by-step explanation:

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The graph of Option C shows a line with a slope of 2 and a y-intercept of 0.

Option C is the correct answer.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The line has a slope of 2 and the y-intercept is 0.

This means,

The line has to pass through y = 0.

i.e (0, 0)

Now,

We see that,

Options B and C has the y-intercept at y = 0.

Option B.

Two points: (0, 0) and (-1, 2)

Slope = (2 - 0) / (-1 - 0) = 2/-1 = -2

Option C.

Two points: (0, 0) and (1, 2)

Slope = (2 - 0) / (1 - 0) = 2/1 = 2

We see that,

Option C has slope = 2.

Thus,

The graph of Option C shows a line with a slope of 2 and a y-intercept of 0.

Option C is the correct answer.

Caleb read a total of 30 pager over 2 hours. After a total of 3 hours of reading this week, how many pages will Caleb have read in all? Solve using unit rates

Answers

Answer:

45 pages

Step-by-step explanation:

Caleb read a total of 30 pager over 2 hours.

To find the unit rates

2 hours of reading = 30 pages

1 hour of reading = x

Cross Multiply

2× x = 30 × 1

2x = 30

x = 30/1

x = 15 Pages.

Hence, he read 15 pages per hour

After a total of 3 hours of reading this week, how many pages will Caleb have read in all?

If;

1 hour = 15 pages

3 hours = x pages

Cross Multiply

x = 3 × 15 pages

x = 45 pages

Hence, Caleb would have read 45 pages in all

It takes 43 facial muscles to frown. This is 26 more muscles than it takes to smile. Write and solve an equation to find the number of muscles it takes to smile. (example: s + 1 = 4)

Answers

Answer:

Number of facial muscles it takes to smile, S = 20

Step-by-step explanation:

Let

Number of facial muscles it takes to smile = S

Number of facial muscles it takes to frown, F = 46

This is 26 more muscles than it takes to smile

F = S + 26

46 = S + 26

Subtract 26 from both sides

46 - 26 = S + 26 - 26

20 = S

S = 20

The number of muscles it takes to smile is 20

Step-by-step explanation:

The scale factor is the number you get after you divide the values of the corresponding sides of both shapesFor this example the 2 side is similar to the 5 side and the 3 side is similar to the 7.5 side. So we make ratios from the first figure to the second figureThat will 2 from the first to 5 five from the second so 2 : 5Then 3 from the first to 7.5 from the second so 3 : 7.5The scale factor must be same for every ratio, or else the transformation is incorrectCheck the ratios, does [tex]2:5=3:7.5[/tex] ?[tex]2:5=\frac{2}{5} =0.4[/tex] [tex]3:7.5=\frac{3}{7.5} =0.4[/tex] yes, so it is a correct transformation

Solve for x. Thank you

Answers

Answer:

x = 11

Step-by-step explanation:

9x + 1 + 100 = 180

9x + 101 = 180

9x = 99

x = 11

Answer:

x = 11

Step-by-step explanation:

the angles are alternate exterior and therefore equal eachother

so 100 = 9x- 1

100- 1 = 9x-1 + 1

99 = 9x

99/9 = 9x/9

11 = x

The engine torque y (in foot-pounds) of one model of car is given by y=−3.75x2+23.2x+38.8, where x is the speed (in thousands of revolutions per minute) of the engine. a. To the nearest ten, what is the engine speed that maximizes torque? revolutions per minute To the nearest hundredth, what is the maximum torque? ft-lbs Question 2

Answers

Answer:

Step-by-step explanation:

If the engine torque y (in foot-pounds) of one model of car is given by y=−3.75x^2+23.2x+38.8

The engine speed is at maximum if dy/dx = 0

dy/dx = -2(3.75)x+23.2

dy/dx = -7.5x + 23.2

since dy/dx = 0

0 =  -7.5x + 23.2

7.5x = 23.2

x = 23.2/7.5

x = 3.093

Hence the maximum torque is 3.09 rev/min

Answers

Answer:

1 1/2 miles

Step-by-step explanation:

Total mileage needed = 3 3/4 mies

Amount taken = 2 1/4 miles

Amount they still need to travel = Total-amoutnt taken.

Amount they need to travel = 3 3/4 - 2/1/4

Convert to improper fractions

Amount they need to travel = 15/4-9/4

Amount they need to travel= 6/4

Amount they need to travel = 1 2/4
