Answer:

Equation of straight line that passes through (-4, 2) and has slope 9/2 is

[tex]y-2=\frac{9}{2} (x+4)[/tex]

Step-by-step explanation:

Equation of straight line in point slope form is given as

[tex]y-y_1=m(x-x_1)[/tex] ---------(2)

Here

[tex]m = \frac {9}{2}[/tex]   and  [tex](x_1, y_1) = (-4, 2)[/tex]

Substituting values in equation (1)

[tex]y-2=\frac{9}{2} (x+4)[/tex]

Answer:

A. 442.05

Step-by-step explanation:

✔️First find the radius of circle J:

θ = 43°

Acr length = 52.8

Thus,

Acr length = θ/360*2πr

Plug in the values

52.8 = 43/360*2*π*r

52.8 = 0.751r

Divide both sides by 0.75

52.8/0.75 = r

r = 70.4 (nearest hundredth)

✔️Find the Circumference of circle J:

Circumference = 2πr

Radius (r) of circle J = 70.4

Plug in the values

Circumference = 2*π*70.4

= 442.34

This is close to the answer in option A. Therefore, the answer is 442.05.

Answer:

1/3 because there's more of the other marbles than red

Step-by-step explanation:

Answer/Step-by-step explanation:

First, find the slope (m) of Line L using the points (0, 5) and (2, 1):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 5}{2 - 0} = \frac{-4}{2} = -2 [/tex]

Slope (m) = -2

✔️Since the line is parallel bro Line L, it would also have the same slope value of -2.

We can use the slope (m) and a point (a, b) of the line to find its equation using the point-slope formula, y - b = m(x - a).

Substitute (a, b) = (3, 0), and m = -2 into y - b = m(x + a):

Thus,

✅y - 0 = -2(x + 3)

Rewrite equation in slope-intercept form

y = -2(x + 3)

✅y = -2x - 6

Step-by-step explanation:

Answer:

We conclude that the equation of the line is:

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Given the data table

x      -3 -5 -7 -9 -11

y      -16 -26 -36 -46 -56

From the table taking two points

Determining the slope between (-3, -16) and (-5, -26)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-3,\:-16\right),\:\left(x_2,\:y_2\right)=\left(-5,\:-26\right)[/tex]

[tex]m=\frac{-26-\left(-16\right)}{-5-\left(-3\right)}[/tex]

[tex]m=5[/tex]

Thus, the slope of the line is:  m = 5

substituting m = 5 and (-3, -16) in the slope-intercept form of the line equation  to determine the y-intercept b

[tex]y = mx+b[/tex]

-16 = 5(-3) + b

-16 = -15 + b

b = -16+15

b = 1

Thus, the y-intercept b = 1

now substituting m = 5 and b = 1 in the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

[tex]y = 5x + 1[/tex]

Therefore, we conclude that the equation of the line is:

Answer:

$10511.075

Step-by-step explanation:

Given :

Interest rate, r =. 1.25% = 0.0125 compounded semianually

Principal = 10000

Number of years, t = 4 years

Compound interest :

A = P(1 + r/n)^nt

A = final amount ; n = number of compounding times per period

n = 2 (quarterly)

A = 10000(1 + 0.0125/2)^2*4

A = 10000(1 + 0.00625)^8

A = 10000(1.00625)^8

A = 10000 * 1.051107529

A = 10511.075

Final. Amount to. Be repaid = $8515.13

I graphed it using slope-intercept form.

Answer:

Slope-intercept form: (y=mx+b) y=3x+10

To graph, place points at (-2, 4), (-3, 1), and (-4, -2), then draw a line connecting them

Step-by-step explanation:

The 10 in the equation represents where the line will intercept the y-axis. The 3x means that for every 1 unit you move to the right, you move 3 units up (or 1 to the left, 3 units down).

Answer:

105 girls

Step-by-step explanation:

The ratio between girls and boys is 3:4, which means for every  3 girls, there are 4 boys. We are trying to solve for the number of girls, so the ratio will be x:140. First let's divide 140 by 4 to find out the value of each part.

We will get 35 for each part.

Multiply 35 by 3 to get 105. There we find that there are 105 girls for 140 boys. Hope this helped :)

Answer:

a) [tex]P(t) = 3166t + 65309[/tex]

b) The slope of 3166 means that each year, the population increases, on average, by 3166 million people.

The P-intercept of 65309 means that the population of Pakistan in 1972 was of 65309 million people.

c) The estimated population of Pakistan in 2027 will be of 239 439 million people.

Step-by-step explanation:

Linear function:

In this question, the linear function for the Population in Pakistan in t years after 1972 is given by the following equation:

[tex]P(t) = mt + P(0)[/tex]

In which P(t) is given in millions of people.

In which m is the slope, that is, the average number by which the population changes each year, and P(0) is the population in 1972.

a) Determine the estimation function P = f (t), where P equals the population of Pakistan and t equals time measured in years since 1972.

In 1972, the population was of 65.309 million. This means that [tex]P(0) = 65.309[/tex].

So

[tex]P(t) = mt + 65.309[/tex]

In 2017, the population was 207.774 million.

2017 - 1972 = 45

This means that [tex]P(45) = 207.774[/tex]. So

[tex]207774 = 45m + 65309[/tex]

[tex]45m = 207774 - 65309[/tex]

[tex]m = \frac{(207774 - 65309)}{45}[/tex]

[tex]m = 3166[/tex]

So

[tex]P(t) = 3166t + 65309[/tex]

b) Interpret the slope and P intercept

Following the explanation before item a:

The slope of 3166 means that each year, the population increases, on average, by 3166 million people.

The P-intercept of 65309 means that the population of Pakistan in 1972 was of 65309 million people.

c) According to this function, what will be the estimated population of Pakistan in 2027 census?

2027 - 1972 = 55

So this is

[tex]P(55) = 3166*55 + 65309 = 239 439[/tex]

The estimated population of Pakistan in 2027 will be of 239 439 million people.

Answer: Six $5 ones and 10 $2 ones.

Step-by-step explanation:

Answer:

Here we do not have the image P, but let's solve this in a general way.

Suppose that we have a point A (x,y)

If we translate the point A n units horizontally (where n can be positive, translation to the right, or negative translation to the left.)

The new point will be (x + n, y)

if we translate the point m units vertically (if m is positive the translation is upwards, if m is negative the translation is downwards), the new point will be (x + n, y + m)

Then if our figure was p (x, y)

The new figure is p(x + 2.5, y + 3.5)

So for every point in the figure, we need to add 2.5 to the x component, and 3.5 to the y-component.

Mary has two friends over, she wants to split half of a cake she has left over into thirds for her and her friends. 1/2 ÷ 3 is 1/6. This means that each friend will get 1/6 of the full cake.

Step-by-step explanation:

I make up stories and know how to divide fractions. To solve a division problem like this you want to take the 3 and turn it into 3/1. then, flip the 1/2 around to it is 2/1. Then, multiply the two together.
