row 2 Answer
2

Answers

Answer:

Step-by-step explanation:

step 1 of 2:  

We got pairs: (-3, y) and (x, 2), to compute the missing x and y values, we plugin the number into the equation.

(-3, y)

y = -3x - 1

y = -3(-3) - 1

y = 9 - 1

y = 8

So we solve this pair as (-3, 8).

(x, 2)

y = -3x - 1

2 = -3x - 1

3 = -3x

x = -1

So we solve this pair as (-1, 2).

Riley wants to find the smallest of the fractions One-sixth, Eleven-twelfths, Five-sixths, and Ten-twelfths. She uses 0 and 1 as benchmarks. Which fraction is closest to 0?

Answers

Answer: 1/6

Step-by-step explanation: Make all of the denominators the same. The least common multiple of 6 and 12 is 12. 1/6 gets multiplied by 2/2 to the equivalent fraction 2/12. 11/12 stays the same. 5/6 is multiplied by 2/2 to get 10/12. 10/12 stays the same. 1/6 is the smallest fraction so it is the closest to 0.

A bicycle with 20 -inch diameter wheels is traveling at 13 mi/h. How many revolutions per minute do the wheels make?

Answers

The revolution per minute done by the wheel of a bicycle is 16.9 rev/min.

What is Velocity?

Velocity is the rate at which a moving object's direction changes as perceived from a certain vantage point and measured by a particular unit of time. Kinematics, the area of special relativity that investigates how bodies move, starts with the fundamental idea of speed.

In order to be explained, the scientific vector quantity known as velocity needs to have both a magnitude and a direction.

As per the given information in the question,

Diameter of wheel = 20 inch

Radius, r = 10 inch

The velocity of the bicycle, v = 13 mi/h.

Revolution, R = v²/r

R = 13²/10

Answers

The given expression has a value of 2.5.

The BODMAS rule is named after the letters in the acronym: B - Brackets, O - Order of powers or roots, D - Division, M - Multiplication. A stands for addition, and S stands for subtraction. According to the BODMAS rule, mathematical statements having several operations must be solved from left to right in the BODMAS order.

Given expression 6 x (2/3 divided by 2) + 0.5

To solve this expression, we must employ the BODMAS rule.

First 2/3 divided by 2

(2/3)/2

= 1/3

Now multiply 1/3 with 6

= 1/3 x 6

= 2

Now add both 2 and 0.5

Write the equation of the line with a slope of 3/2that contains the point ( — 4, − 2).

Answers

The equation of line with a slope of 3/2 which passes through point (-4,-2) is y = (3/2)x + 4.

What is the equation of line with the given point and slope?

The equation of line is expressed as;

y = mx + b

Where m is slope and b is y-intercept.

Given the data in the question;

Point (-4, -2 )

x = -4y = -2Slope m = 3/2

First, we determine the y-intercept 'b'.

Plug the point and slope slope into the equation of line formula and solve for b.

y = mx + b

-2 = (3/2)(-4) + b

-2 = (3)(-2) + b

-2 = -6 + b

b = -2 + 6

b = 4

Now, plug the slope and y-intercept into y = mx + b to determine the equation of the line.

y = mx + b

y = (3/2)x + 4

Therefore, the equation of the line is y = (3/2)x + 4.

Write an equation for the trend line shown on the scatter plot. ASP

Answers

Answer:

y=5x+15

Step-by-step explanation:

the equation of a line is y=mx+b where b is the y-intercept and m is the slope.

if you look at the graph you will see that your line intecpts the y axes at b=15 or that would be your y value where the line touches the edge.

now you just have to find your slope. slope is y/x or rise/run

so by looking at the graph at where our line touches the corner of a square. we just need to find 2 of those. we can use (0,15) and (1,20) the distance from 15 to 20 is 5 so that is our rise or change in y. the distance from 0 to 1 is 1 so that is our change in x or run. now just put rise over run so 5/1 which is just 5.

lastly we fill out our equation y=mx+b

our slop m is 5 and our y-intercept b is 15 so y=5x+15

The amount to be credited, based on the invoice amount and the payment, is $612.24. The balance outstanding is $2, 387.76

Credit terms of 2/10, n/30 mean that if a buyer pays their payables in 10 days, they get a 2% discount. If they don't, then they'd have to pay the full thing in 30 days.

The days till the partial payment was made was:

The discount of 2% would apply on the payment of $600 so the amount to be credited is:

= 600 / (1 - 2%)

= $612.24
