Answer:
X is 38, y is 27.
Step-by-step explanation:
This is because you are subtracting on the 90 degree angles.
Answer:
The answer is 27 degrees for x, and 38 degrees for y.
Step-by-step explanation:
There are many ways you could do this. The easiest one for me was if you look at the left side of the 180 degree line (CD), you take away 90 (straight angle) from 63, which equals 27 degrees (answer for x). Then, add up all the angles on the left side of the 180 degree line. However, you need to first work out a, which is 180-128=52 degrees. Now you can add them up. 52 degrees (a) plus 27 (m) plus 63 (n) = 142 degrees. Then take away 180 from 142, which equals 39 degrees for y. If you want to check this Add up all your known angle on the left side of the 180 degree line. 52 plus 27 plus 63 plus 38, which equals 180 degrees, which is correct.

Find the coordinates of the point(s) of intersection between the following functions: y=x-1 and y=117/x-5
Answer:
(-8.-9) and (14,13).
Step-by-step explanation:
y=x-1
y=117/x-5
As the 2 terms in x are both equal to y:
x-1 = 117/x-5
(x-1)(x-5) = 117
x^2 - 6x + 5 - 117 = 0
x^2 - 6x - 112 = 0
(x + 8)(x - 14) = 0
x = -8, 14.
When x = -8, y = -8-1 = -9
When x = 14, y = 14-1 = 13.
The required coordinate points are (-8.-9) and (14,13).
Functions and valuesGiven the following equations
y=x-1
y=117/x-5
Equating both function will give
x-1 = 117/x-5
(x-1)(x-5) = 117
x^2 - 6x + 5 - 117 = 0
x^2 - 6x - 112 = 0
(x + 8)(x - 14) = 0
x = -8, 14.
When x = -8, y = -8-1 = -9
When x = 14, y = 14-1 = 13.
Hence the required coordinate points are (-8.-9) and (14,13).

What is the measure of the angle?
9514 1404 393
Answer:
d. 32°
Step-by-step explanation:
Vertical angles are congruent, so ...
5x +2 = x +26
4x = 24
x = 6
(x +26)° = (6+26)° = 32°
The measure of the angle is 32°.
_____
Additional comment
Vertical angles share a vertex. This means B and E are two names for the same point.

The sides of a rectangle are in the ratio of 5:6. If its longer side is 7.2 in., find the shorter side, the perimeter, and the area of this rectangle.
Answer:
The shorter side is 6.
The perimeter is 26.4 inches.
The area is 43.2 inches[tex]^{2}[/tex]
Step-by-step explanation:
The ratio 5;6 and the given longer side is 7.2 in.
Since it is the longer side, the '6' in the ratio is 7.2 in.
Let x be the shorter side
5:6 = x : 7,2
Divide 7.2 to 6.
7.2 ÷ 6 = 1.2
Then multiply 1.2 to 5.
1.2 * 5 = 6
So the shorter side is 6.
L = 7.2
W = 6
Now to find the perimeter, let's use the formula
P = 2L + 2W
Let's put the values in the formula
P = 2(7.2) + 2(6)
P = 14. 4 + 12
P = 26.4
The perimeter is 26.4 inches
To find the area, let's use the formula
A = LW
A = (7.2)(6)
A = 43. 2 inches[tex]^{2}[/tex]
Answer:
shorter side= 6
p= 26.4
a= 43.2

i need help it is due today
Answer:
8
Step-by-step explanation:
Using the Heron's formula we can find that the total area of the triangle is 84 inches.
Then, to find the height of the triangle, you have to multiply the area by 2 since the formula for the area of a triangle is (h*b)/2
Now, when we multiply 84 and 2 we get 168, so you have to divide 168 by 21 to find 8.

Jodie wants to raise money for a school trip by selling raffle tickets at a basketball game. She sells each ticket for 50 cents, and she sells two and a half rolls of tickets. If each roll of ticket has 200 tickets, how much money did Jodie make?
Answer:
250 dollars
Step-by-step explanation:
t = tickets
t = 200
Two and a half rolls tickets = (200 x 2) + 200/2) = 400 + 100 = 500
500 tickets x 50 cents = 25000 cents
convert cents to dollars (move decimole point over left 2 units)
25000 = 250 dollars

Answer:
Step-by-step explanation:
-6x + y = -6 Add 6x to both sides
y = 6x - 6 So the slope of the new line is 6
The point the new line has to go through is (-4,0) That will determine b.
y = 6x - 6
x = - 4
y = 0
0 = 6*(-4) + b Combine
0 = - 24 + b add 24 to both sides
24 = b
Answer: y = 6x + 24
