Answer:
y = 2x - 1
Step-by-step explanation:
4x - 2y = 2
So I'm assuming that your goal is to solve for the value of y in terms of x
First: the whole equation can be divided by 2
2x - y = 1
Second: subtract 2x from both sides
-y = -2x + 1
Third: divide each side by -1
y = 2x - 1

What is the graph of one cycle of a sine curve with amplitude 5, period pi, and a>0?
What is an equation for the sine curve in the form y=asinb0?
a. y=2sin50
b. y=5sinpi0
c. y=5sin20
d. y=5sin1/2 0
Answer:
c is correct
Step-by-step explanation:
if u have the equation y = a sin b (x),
a is the amplitue (regardless of + or - before it) and 2pi / b = period. so we can deduce that a = +5 or -5 and b = 2, but then it says a>0, so therefore a must be 5 and b is still 2, so the equation is y= 5 sin2(O)

What is the surface area?
Someone please help
Answer:
134 square inches
Step-by-step explanation:
To find surface area, you must find the individual area of each face of the shape. There are 6 faces on every cube or other rectangular prism, so you must perform 3 equations, as every face has an identical face on the opposite side. The formula for regular area is Length (l) times Width (w).
Large sides on front and back: 8x6=48
Slim sides to the right and left: 1x6=6
Slim sides on top and bottom: 8x1=8
Then combine:

The 25th term of the given arithmetic sequence is -19.
The given arithmetic sequence is 53, 50, 47, 44, 41.
What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is an=a+(n-1)d
Here the first term of the sequence is a=53 and the common difference is
50-53=-3
Put, a=53, d=-3 and n=25 in the general form an arithmetic sequence, we get
a25=53+(25-1)×(-3)
= 53+24×(-3)
= 53-72
= -19
Therefore, the 25th term of the given arithmetic sequence is -19.

How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

A= 12, base= 16

Semi Circle should be something like =(1/2) pir^2
diameter= hypotenuse= sqrt(12^2 +16^2) = 20
radius= r= d/2= 20/2
Semi Circle= (1/2) pi 10^2= 50pi= 157.0796327
Total = 480+157.0796327=637.0796327. Rounding to the nearest hundred would give me 637.08??
Answer and Step-by-step explanation:
Yes, all of your calculations are correct!!
The area of one rectangle is 192, and since there are 2 rectangles, we multiply 192 by 2, which results in 384.
The area of a triangle is [tex]A = \frac{(Height)(Base)}{2}[/tex], which you got to be 96.
The Semi Circle would have half of the area of a circle, so you are correct when you multiply the equation by [tex]\frac{1}{2}[/tex].
To find that diameter, we need to use the Pythagorean Theorem.
[tex]12^{2} + 16^{2} = d^{2} \\\\144 + 256 = d^{2} \\\\400 = d^2\\\\d = 20[/tex]
So the diameter is 20, and the radius is 10 (20 divided by 2 = radius).
Plug that into the equation, and you get the answer to be [tex]50\pi[/tex], or 157.0796327.
157.0796327 + 384 + 96 = 637.08 (rounded to the nearest hundredth).

The cost for the raw materials of marble countertops, can be represented by the function , where is the area of the countertops. The retail markup, can be represented by the function. Which function can be used to find the marked-up price of a marble countertop depending on the area?
Answer:
[tex]m(c(a)) = 4.8875a[/tex]
Step-by-step explanation:
The missing parameters are:
[tex]c(a) = 4.25a[/tex] --- Cost of marble countertops
[tex]m(c) = 1.15c[/tex] --- Cost of retail markup
Required
The cost of marked up price
This implies that we calculate m(c(a))
We have:
[tex]c(a) = 4.25a[/tex]
[tex]m(c) = 1.15c[/tex]
[tex]m(c) = 1.15c[/tex] can be written as:
[tex]m(c(a)) = 1.15*c(a)[/tex]
Substitute: [tex]c(a) = 4.25a[/tex]
[tex]m(c(a)) = 1.15*4.25a[/tex]
[tex]m(c(a)) = 4.8875a[/tex]
Hence, the cost of marked up price is: [tex]m(c(a)) = 4.8875a[/tex]

c) 5x + 13x = 180
d) 5x = 13x
no links picture above
Answer:
C) 5x + 13x = 180
Step-by-step explanation:
As, the sum of the angles of the above diagram is 180 °
So if we add them we get 180°
So, 5x + 13x = 180°
So option (C) is right
