Find angles x and y.
I really need this as fast as possible, is it alright if u can help?
Answer:
x=62, y=62
Step-by-step explanation:
the diagonal line to the 62 angle and the diagonal line towards the left of the x angle are parallel and so are the two horizontal lines. we know angle 3 is 62 now, so y= 180 - 46 - 62 = 72
by alternate interior angles, y=angle 2 and angle2=x so x=72
rewrite 4x+2y=20 so that y is a function of x

answer in feet and inches
b) (2 yd. 2 ft.) + (7 yd. 9 in)
Answer:
12 feet 9 inches
Step-by-step explanation:
There are 3 feet in a yard, and 12 inches in a foot. Multiply those together and you get 36 inches in a yard.
2 yards × 36 inches/yard = 72 inches
2 feet × 12 inches/foot = 24 inches
72 inches + 24 inches = 96 inches
------------
7 yards × 36 inches/yard = 252 inches
252 inches + 9 inches = 261 inches
==============
Add those together:
96 inches + 261 inches = 357 inches
Then to convert to feet again, you need to divide by 12 and find the remainder. I prefer to do it with a calculator like this, but you can do it however you prefer:
357 ÷ 12 = 29.75 feet (round down)
12 × 29 = 348 inches in 12 feet
Then find the remainder:
357 - 348 = 9 inches
12 feet 9 inches

Raffle tickets are being sold for a fundraiser. The function a(n) relates the
amount of money raised to the number of tickets sold, n.
It takes as input the number of tickets sold and returns as output the amount
of money raised.
a(n) = 3n - 30
Which equation represents the inverse function n(a), which takes the money
raised as input and returns the number of tickets sold as output?
The money raised depends only on the number of tickets sold, the inverse equation is found by making the tickets sold the subject.
[tex] \underline {n =\frac{a(n) }{3} + 10}[/tex]
How can the inverse function be found?The given parameters are;
a(n) = The amount of money raised
n = The number of tickets sold
a(n) = 3•n - 30
Solution;
The equation that takes the amount of money raised and returns the number of tickets sold is found as follows;
a(n) = 3•n - 30
a(n) + 30 = 3•n
Therefore;
[tex]n = \frac{a(n) + 30}{3} = \frac{a(n) }{3} + 10[/tex]
The number of tickets sold,
[tex] \underline {n =\frac{a(n) }{3} + 10}[/tex]

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the maximum height reached by the rocket, to the nearest tenth of a foot.
y=−16x^2+146x+137
Answer:
470.1
Step-by-step explanation:
Since this is a parabola that opens down, the maximum height is where the graph has a horizontal tangent line.
This is where the derivative=0
Since it is a parabola that opens down, we do not need to test the sides of the point where the derivative=0 as the vertex is a local maximum and the only point with a horizontal tangent.
y=[tex]-16x^2+146x+137[/tex]
y'=[tex]-32x+146[/tex]=0
-32x+146=0
x=[tex]\frac{146}{32}[/tex]=[tex]\frac{73}{16}[/tex] This is the x-coordinate of the vertex
Now plug this back into the original equation to find the maximum height.
f(73/16)=[tex]-16(\frac{73}{16})^2+146(\frac{73}{16} )[/tex]+137
=[tex]\frac{-73^2}{16} +666.125+137[/tex]
=-333.0625+666.125+137
=470.0625
To the nearest tenth this is 470.1

leena bakes a loaf of bread. She eats 1/8 of the loaf and gives 1/6 of it to each of her 3 friends. What fraction of the loaf of bread is left
Answer:
3/8
Step-by-step explanation:
So, Leena eats 1/8 of the bread first.
Now, she gave 1/6 of the bread to EACH of her 3 friends.
So you will need to do 1/6*3, which is 3/6=1/2.
Now you want to do 1/8+1/2 = 1/8+4/8 = 5/8.
This means 5/8 of the bread is gone.
Now you will need to do 1-5/8 = 8/8-5/8=3/8.
Therefore, 3/8 of the bread is left.

Explain what the vertical line test is and how it is used.
Answer:
The vertical line test is a test to determine if a relation or its graph is a function or not. For a relation or graph to be a function, it can have at most a single y-value for each x-value. Thus, a vertical line drawn at any x-position on the graph of a function will intersect the graph at most once.
