Answer:

y = 2/5x + 39/5

Step-by-step explanation:

point slope form is y = mx + b

so far we have y = 2/5x + b

m is slope which is given. We need to find b which is y-intercept.

They give us the point (-2,7). We can plug this into the equation to find b.

7 = 2/5(-2) + b

7 = -4/5 + b

b = 39/5

The equation now looks like y = 2/5x + 39/5

Point (5, 19)

Step 2: Find slope m

Answer:

-2

Step-by-step explanation:

Answer: 55%

1. 279 - 180 = 99

2. 99 divided by 180 = 0.55

3. 0.55 x 100 is 55.

55 is the percentage

Answer:

137$

Step-by-step explanation:

Let the slope of the equation be

[tex]m=\dfrac{\Delta y}{\Delta x}[/tex]

where y = Total pay

x = T-shirts sold

Take any two values of x and corresponding y value

[tex]m=\dfrac{71-68}{2-1}\\\Rightarrow m=3[/tex]

The equation will be

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

Finding b

[tex]68=3\times 1+b\\\Rightarrow b=68-3\\\Rightarrow b=65[/tex]

The equation is

[tex]y=3x+65[/tex]

Now sasha sells 24 shirts [tex]x=24[/tex]

[tex]y=3\times 24+65\\\Rightarrow y=137[/tex]

Sasha would earn 137$ on that day.

Answer:

Answer is 36,220

Step-by-step explanation:

Answer:

1782 cm³

Step-by-step explanation:

First, you measure the volume of the cuboid as a whole which is length x breadth x height, 9 x 12 x 18 = 1944 cm³. Then measure the volume occupied by the space, 3 x 3 x 18 since the hole runs along the entire length = 162 cm³.

Then you subtract the volume occupied by the hole from the volume of the cuboid in total, 1944 - 162 = 1782 cm³

Answer:

24v

Step-by-step explanation:

simply multiply perform the distributive property. so multiply 6 and 4 and you should get 24. after just add in the v.

X=90 because p and q perpendicular and   41+2y = 90 so  2y = 49 y=24.5

Answer:

8:4

Step-by-step explanation:

Given that,

The ratio of the areas of similar polygons is 64: 16, A₁:A₂=64: 16

We need to find the ratio of their sides. For similar polygons, the ratio of  the area is proportional to the square of the ratio of their corresponding sides.

Let sides are x₁ and x₂. So,

[tex]\dfrac{A_1}{A_2}=(\dfrac{x_1}{x_2})^2\\\\\dfrac{x_1}{x_2}=\sqrt{\dfrac{A_1}{A_2}} \\\\=\sqrt{\dfrac{64}{16}}\\\\=\dfrac{8}{4}[/tex]

So, the required ratio is 8:4.

Answer:

The population is the total number of the universities  graduates  i.e [tex]N = 300,000[/tex]

Step-by-step explanation:

From the question we are told that

  The number of students that are consider is  n = 10,000

   The total number of graduates is  [tex]N = 300,000[/tex]

  The mean is [tex]\= x = \$125 , 000[/tex]

Here the population is The total number of graduates with value  [tex]N = 300,000[/tex], this is because a population is the pool from with a sample is drawn and in this case the pool is [tex]N = 300,000[/tex] while the sample with is drawn is  n = 10,000

Answer:

Step-by-step explanation:

Given the coordinates of three vertices of a square as A(1, –1), B(6, –1), and C(6, 4). The area of the square is expressed as;

A = L² where;

L is the one of the side length of the square.

Note that all the sides of a square are equal;

To get one of the side length, we will find the distance between any two of the coordinates points. Using the coordinates A(1, –1), B(6, –1)

L = AB = √(x2-x1)²+(y2-y1)²

L = √(6-1)²+(-1-(-1))²

L = √5²+0²

L = √25

L = 5

Area of the square = 5²

Area of the square = 25units²

Hence the area of the square is 25units²

Answer:

6 is the GCF

Step-by-step explanation:

GCF (24, 42, and 96)

GCF = 6

24 / 6 = 4

42 / 6 = 7

96 / 6 = 16

Answer:

x=1 (Ans)

Step-by-step explanation:

2..-4x-6=-10x

-4x+10x=6

6x=6

x=6 divided by 6

Therefore, x=1(Ans)

The answer would be aas

Answer:

The answer to this question would be AAS (Angle-Angle-Side)

Step-by-step explanation:

The triangles both have the same side and another same angle as shown in the image, but to make this AAS, there must be another angle, which is the center point of both triangles... these are the same because they are vertical angles.

Answer:

p÷3=h

My logic:

if you want the p (pages) to directly relate to h then this eqation represents that what ever p is divided by 3 will give you h.

Answer:

25

Step-by-step explanation:

take C as what Cj has, and J what Jordan has.

Cj has $50 more than Jordan has, so:

C = 50 + J

Together they have $100, so:

C + J = 100

is a system of 2 equations with 2 unknown (C and J):

C - J = 50

C + J = 100

Adding both equations:

2C = 150 ⇒ C = 75

From second equation: J = 25
