15 POINTS PLEASE HELP SOLVE AND EXPLAIN

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].

Step-by-step explanation:

GIven that GR= x+5 and GP= 2x-3 which expression below calculates the perimeter of this gate?

The shape of the gate is rectangular.

Hence, the Perimeter of a rectangle (the gate) = 2L + 2W

Where :

L = GR = x + 5

W = GP = 2x - 3

Hence,the perimeter of the gate is

P = 2(x + 5) + 2(2x - 3)

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: 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!

hope this helps!

Answer:

a) m/4 miles per hour

b) 7m/12 miles per hour

Step-by-step explanation:

Mathematically, at any point in time;

Time = distance/speed

The distance here at any point is m mph

a) For the time spent walking home

Time = m/4 miles per hour

b) We add the time walking to the friend’s house and the time that it took to walk home

That would be;

m/4 + m/3 = 7m/12 miles per hour

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:

58 yards

Step-by-step explanation:

The Pythagorean Theorem states that:

[tex]a^{2} +b^{2} =c^{2}[/tex]

Where c is the hypotenuse, and a and b are the two legs of the right triangle. Substituting in 40 and 42 for a and b, respectively:

[tex]40^{2} +42^{2} =c^{2}[/tex]

Now, we isolate c:

[tex]c= \sqrt{40^{2} +42^{2} }[/tex]

Therefore, c is equal to 58, so the hypotenuse is 58 yards

Hope this helps!

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
