Given:

A line passes through two points (-7, -5) and (-7, -2).

To find:

The equation of the line.

Solution:

If a line passes through two points, then the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The line passes through two points (-7, -5) and (-7, -2). So, the equation of the line is

[tex]m=\dfrac{-2-(-5)}{-7-(-7)}[/tex]

[tex]m=\dfrac{-2+5}{-7+7}[/tex]

[tex]m=\dfrac{3}{0}[/tex]

[tex]m=\infty[/tex]

Here, slope is ∞. It means it is a vertical line of the form [tex]x=a[/tex], where a is constant.

It the given points x-coordinates are same, i.e., -7. So, equation of the line is

[tex]x=-7[/tex]

Therefore, the equation of the line is [tex]x=-7[/tex].

2.5 x 2.5 = 5 m

9 x 9 = 18m

Answer:

6/5

Step-by-step explanation:

You can see in the picture that when x goes up by 10, y goes up by 12. Since the formula for slope is change in y/change in x, you get 12/10 = 6/5

I believe the awnser is A

Answer:

52[tex]\pi[/tex]

Step-by-step explanation:

We see that the radius of the big circle is 8m, and we see that the it is also the diameter of the second smallest circle. We also see that this diameter is split into two equal parts, and since the entire length is 8, each part will be 4. So what we need to do is find the area of each circle.

First we can start by finding the area of the smallest circle. The radius of this circle will be 4/2, 2. So the area of this circle will be [tex]\pi[/tex][tex]r^{2}[/tex], and in this case 4[tex]\pi[/tex].

Then we need to find the area of the bigger shaded portion, which will be the area of the big circle, minus the area of the smaller white circle.

First, lets find the are of the big circle, which again, will be [tex]\pi[/tex][tex]r^{2}[/tex]. This time, we plug in a radius of 8, and we get 64[tex]\pi[/tex].

Next we find the area of the smaller white circle, again [tex]\pi[/tex][tex]r^{2}[/tex]. We use a radius of 4 this time, giving us an area of 16[tex]\pi[/tex].

Now we subtract the two values we found previously to find the area of the just the bigger shaded portion. That value will be 64[tex]\pi[/tex]-16[tex]\pi[/tex], which is 48[tex]\pi[/tex]

We then take 48[tex]\pi[/tex], and we add the small shaded portion, which had an area of 4[tex]\pi[/tex], and we add them, giving us a total of 52[tex]\pi[/tex].

Hope this helped.

Answer: Y=2.50x+b

Step-by-step explanation:

Thats not the whole answer, you didnt attach the graph but what you need to do is find the y-intercept and put that into b and theres your equation. The y-intercept(B) represents the initial  money that joe had in his savings the 2.50x part or the slope is the money that he states he can add each week.

Answer:

slope is how much money joe adds to his account savings each week

the y intercept is the money he had before he started waiting

for the equation the slope is $2.50 and the y intercept is where the line hits the y axis but because you don't have a graph I don't know how to help you with this part, maybe someone else can!

Answer:

Conversely, if n is divisible by 5, then n is the sum of five consecutive integers. In particular, this gives n = 5m + 10 = 5(m + 2) and, since m + 2 is an integer, this shows n is divisible by 5

Answer: 99 cm

Step-by-step explanation:

To calculate the area of a triangle, we use the formula:

A = H x B  divided by 2

If we add our numbers shown, we get:

A = 18 x 11 = 198

198 ÷ 2 = 99

Therefore we get 99 as the answer.

Area = 99 cm

Answer:

3y-1 = 2y+7

y-1 = 7

y = 8

5(8) + 6 = 5x - 9

46 = 5x - 9

55 = 5x

x = 11

Answer:

The correct pairs of equivalent expressions are:

(5 + 2b)+(2b + 3/2) <--> 4b + 13/2

(-10 + b)+(7b - 5) <---> 8b - 15

(-14 + 3/2b)-(1 + 8/2b) <----> -15 - 5/2b

(7/2b - 3)-(8 + 6b) <-----> -5/2b - 11

Answer:

All real numbers are solutions

Step-by-step explanation:

Let's solve your equation step-by-step

3(x+2)=5x+1−2x+5

Step 1: Simplify both sides of the equation

3(x+2)=5x+1−2x+5

(3)(x)+(3)(2)=5x+1+−2x+5(Distribute)

3x+6=5x+1+−2x+5

3x+6=(5x+−2x)+(1+5)(Combine Like Terms)

3x+6=3x+6

3x+6=3x+6

Step 2: Subtract 3x from both sides

3x+6−3x=3x+6−3x

6=6

Step 3: Subtract 6 from both sides

6−6=6−6

0=0

Answer:

I will change my awnser when you tell me but what are the awnser choices

Step-by-step explanation:

The graph which represents the function y = 2x - 4​ is shown below.

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

y = 2x - 4​

Now,

To find four points of y = 2x - 4, we can choose any four values of x and plug them into the equation to find the corresponding values of y. For example, if we choose x = -2, 0, 1, and 2, we get:

When x = -2, y = 2(-2) - 4 = -8 - 4 = -12. So (-2,-12) is a point on the line.

When x = 0, y = 2(0) - 4 = 0 - 4 = -4. So (0,-4) is a point on the line.

When x = 1, y = 2(1) - 4 = 2 - 4 = -2. So (1,-2) is a point on the line.

When x = 2, y = 2(2) - 4 = 4 - 4 = 0. So (2,0) is a point on the line.

Therefore, by the given function answer will be shown below.
