Answer:
x = -5
Step-by-step explanation:
Given that it is a vertical line, we know that it will only go through one x-value.
We are also given a point, (-5, -3).
This point tells us that the vertical line only goes through the x-value -5, so the equation will be x = -5.

Find the area of the equilateral triangle
Answer:
Step-by-step explanation:
Suppose that the side length is s. Imagine that one side is level. Draw a vertical line through the top vertex perpendicular to the base (level side). Label this vertical line "h." Then h and s are related as follows:
√3 h
sin 60 degrees = ------- = --------
2 s
s√3
and so h = the height of the triangle = -----------
2
The area of this triangle is (1/2)(base)(height), which here is:
(1/2)(s/2)( s√3 /2), or
(s^2)√3
A = ---------------

4c- 3 = x+15 pls help!!
Answer:
x = 4c - 18
Step-by-step explanation:
=> 4c-3 = x+ 15
Subtracting 15 to both sides
=> x = 4c-3-15
=> x = 4c - 18
Answer:
x=6
Step-by-step explanation:
4x- 3 = x+15

In ∆ABC the angle bisectors drawn from vertices A and B intersect at the point D. Find m∠ADB if:
m∠A = α, m∠B = β
Answer:
Pretty easy (if you know geometry)!
Step-by-step explanation:
First, we know that A and B have angle bisectors. This means the angles that are divided by that angle bisector are equal (or their measures).
Thus, m<DBA= 1/2 Beta; m<DAB=1/2 Alpha.
Time to find m<ADB. Using the sum of all angles in a triangle = 180* theorem, we can come up with this equation:
[tex]180= m<ADB+\frac{1}{2} \alpha +\frac{1}{2} \beta[/tex]
So, solving:
[tex]180-\frac{1}{2} \alpha -\frac{1}{2} \beta =m<ADB[/tex]
So there you go! Hope this helps!

a Runway is 3100 ft long and 65 ft wide what is the area of the runway in feet squared
Answer:
201, 500ft²
Step-by-step explanation:
The formula for calculating area in this case is;
A = w × l
This means we're going to take the width of the runway (65ft) and multiply it by the length of the runway (3100ft).
(To make it easier on paper, you can swap the two numbers around, so the higher number is on top, and the smaller number is on the bottom - 3100 × 65. It won't change the answer, but it will make it quicker and easier to get to the result, and lessens the chances making a mistake.)
So the equation you need to do is;
3,100 × 65 = 201, 500.
Add on the units, and there's your answer;
201, 600ft²
Hope this helped!

Answer:
53 sweets.
Step-by-step explanation:
The mean out of 10 bags of sweets is 42. That means that all the numbers of sweets added up would be 420.
39 + 40(2) + 41(5) + 43 + x = 420
39 + 80 + 205 + 43 + x = 420
367 + x = 420
x = 53.
So, in the 10th bag, there are 53 sweets and a sugar high for whoever eats that many sweets.

The ratio of girls to boys at a local elementary school is 3:4.
a. If there are a total of 45 girls in the school, how many boys are there?
b. At another school across town, the ratio of girls to boys is 5:7. How many total
students are there in the school if there are 95 girls at that ratio?
Answer:
a. 60 boys
b. 228 total students
Step-by-step explanation:
a. If there are 45 girls and the ratio of girls to boys is 3:4, then there are 60 boys. The common multiple is 15.
3 * 15 = 45
4 * 15 = 60
45:60 = 3:4
——————————
b. First we need to find out how many boys there are.
95 / 5 = 19
19 * 7 = 133
So, there are 133 boys and the given number of girls is 95. To find out how many total students there are, we need to add 133 and 95.
133 + 95 = 228

What is the result of subtracting the second equation from the first?
-4x - 2y = -2
x - 2y = 9
Answer:
-5x + 0y = -11
The y terms are eliminated
Step-by-step explanation:
- 4x – 2y = -2
X - 2y = 9
We want to subtract the second equation from the first
Distribute a minus sign to all the terms in the second equation
- 4x – 2y = -2
X - 2y = 9
= (-5x + 0y = -11)
PLZ HELP!! HURRY!!!30POINTS!!
Answer & Step-by-step explanation:
For this problem, we will be using the tangent trig ratio because we are dealing with the opposite side and the adjacent side of the triangle. Although cosine may be a good ratio to use as well, it is not the best ratio to use because if you were to use the cosine ratio, you will have more steps to complete in order to solve the problem. Plus, we are not dealing with the hypotenuse side of the triangle. Therefore, it is best to use the tangent ratio because it is more efficient and it corresponds to the side lengths we are using.
On the next page, we are given a Venn Diagram. We are asked to tell the difference between finding the angle and finding the side. Then, we are asked to find the similarity between them.
When solving for the unknown side, you have to flip the equation because one of the sides will be known as a variable.
When solving for the unknown angle, you have to use the inverse of the trig ratio that you are using for that problem.
The similarity between the two is that they will always use one of the trig ratios.
