Answer all parts of the question please!
what proofs should i use for all these steps?
Answer:
1, 2, 5, 12, 13
Step-by-step explanation:
∠1 = 90 is given, which is a right angle
∠3 = 90 as well because ∠1 and ∠3 are vertically opposite
∠3 = ∠8, because ∠1 and ∠8 are same side exterior angles, which are the same
Therefore ∠3 must be congruent to ∠8

Your gym membership costs $30 to join and $25 per month. Which equation gives the total costs y, for a membership that lasts x months?
Answer:
y=$25x+30
Step-by-step explanation:
This is the correct answer. The reason is that the equation is y=mx + b. b is like y-intercept, and that answer would be $30. $25x is correct because the question says per month, and when you see that it means ¨x¨.

[tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex] is equivalent to [tex]sin(\frac{-\pi }{2} )[/tex].
What is trigonometric expression?Trigonometric expressions are non-routine appearing problems. They are unfamiliar because the language of trigonometry looks foreign and complicated. In order to learn how to simplify or reduce the complexity of trigonometric expressions, we first need to examine the identities we need to utilize.
It is one of the identities of trigonometry
sinAcosB - cosAsinB = sin(A - B)
Given expression
[tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex]
It is in form of sinAcosB - cosAsinB = sin(A - B)
⇒ [tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex] = [tex]sin(\frac{\pi }{12}-\frac{7\pi }{12} )[/tex]
⇒ [tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex] = [tex]sin(\frac{-6\pi }{12} )[/tex]
⇒ [tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex] = [tex]sin(\frac{-\pi }{2} )[/tex]
Hence [tex]sin(\frac{\pi }{12})cos(\frac{7\pi}{12}) -cos(\frac{\pi }{12})sin(\frac{7\pi }{12})[/tex] is equivalent to [tex]sin(\frac{-\pi }{2} )[/tex].

Susan won $2000 and invested it into an account with an annual interest rate of 3.2%. If her investment were compounded monthly, which expression best represents the value of her investment after t years
Answer:
FV= PV*(1+i)^t
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $2,000
Interest rate (i)= 3.2% = 0.032
Number of periods= t
To calculate the future value (FV) of the investment, we need to use the following formula:
FV= PV*(1+i)^t
For example, Susan invests for 4 years:
FV= 2,000*(1.032^4)
FV= $2,268.55
The expression best represents the value of her investment after t years is [tex]FV= PV\times (1+i)^t[/tex]
Calculation of the expression:Since
Susan won $2000 and invested it into an account with an annual interest rate of 3.2%.
Here Number of periods= t
Therefore we can conclude that The expression best represents the value of her investment after t years is [tex]FV= PV\times (1+i)^t[/tex]

PLZ HELP I DONT UNDERSTAND (show steps)
Answer:
a= −b/x
Step-by-step explanation:
Let's solve for a.
ax2+bx=0
Step 1: Add -bx to both sides.
ax2+bx+−bx=0+−bx
ax2=−bx
Step 2: Divide both sides by x^2.
ax2x2=−bxx2
a=−bx
Answer:
Step-by-step explanation:
perfect sqaure formula (u+w)²=u²+2uw+w²
ax²+bx+c=0 divide by a
[tex]x^{2} +\frac{bx}{a} + \frac{c}{a} =0[/tex] so u=1, 2uw=2*1*w= b/a, so w=b/2a
[tex](x^{2}+ \frac{bx}{a} +\frac{b^{2} }{4a^{2} } ) +\frac{c}{a} -\frac{b^{2} }{4a^{2} }=0[/tex] now that we formed the perfect sqare solve
[tex](x +\frac{b}{2a} )^{2} +\frac{c*4*a-b^{2} }{4a^{2} } =0[/tex] but we can factor a negative in front of the fraction
[tex](x+\frac{b}{2a} )^{2} -\frac{b^{2} -4ac }{4a^{2} } =0[/tex] now isolate the 2 terms and squareroot both sides
[tex]\sqrt{ (x +\frac{b}{2a} )^{2}} =\sqrt{ \frac{b^{2} -4ac }{4a^{2} } }[/tex] and you will be left with
[tex]x +\frac{b}{2a} =\ + - \frac {\sqrt{ b^{2} -4ac} }{2a }[/tex] subtract b/2a from both sides
x= [tex]\frac{-b+ - \sqrt{b^{2}-4ac } }{2a}[/tex]

Jenny got a haircut before school started. The stylist cut 0.36 inch off Jenny's hair. Which fraction and percent are equivalent to the amount of Jenny's hair the stylist cut off?
Answer:
The fraction equivalent to the amount of Jenny's hair the stylist cut off is [tex]\frac{9}{25}[/tex] inch.
The percentage equivalent to the amount of Jenny's hair the stylist cut off is 36% inch.
Step-by-step explanation:
From the question, the stylist cut 0.36 inch off Jenny's hair.
To determine what fraction is equivalent to the amount of Jenny's hair the stylist cut off, we will express 0.36 inch as a fraction.
[tex]0.36 = \frac{36}{100}[/tex]
Then, we will reduce [tex]\frac{36}{100}[/tex] to a fraction in its lowest term
[tex]\frac{36}{100} = \frac{9}{25}[/tex]
Hence, the fraction equivalent to the amount of Jenny's hair the stylist cut off is [tex]\frac{9}{25}[/tex] inch.
For the percentage equivalent to the amount of Jenny's hair the stylist cut off, we will express [tex]\frac{9}{25}[/tex] as a percentage. That is
[tex]\frac{9}{25} \times 100[/tex]%
= 36%
Hence, the percentage equivalent to the amount of Jenny's hair the stylist cut off is 36% inch.
Which of the following points lies on the line 3y=2x-1?

Answer:

What is an equation of a line?The standard form of the equation of a line is given as:
ax + by + c = 0.
Here a, and b, are the coefficients, x, and y are the variables, and c is the constant term.
We have,
Equation of a line:
3y = 2x - 1
We need to check which point lies on the line.
A = ( 2, 6 )
3 x 6 = 2 x 2 - 1
18 = 4 - 1
18 ≠ 3
B = ( 1, 2 )
3 x 2 = 2 x 1 - 1
6 = 2 - 1
6 ≠ 1
C = ( 2, 1 )
3 x 1 = 2 x 2 - 1
3 = 4 - 1
3 = 3
D = ( -2, 1 )
3 x 1 = 2 x (-2) - 1
3 = -4 - 1
3 ≠ -5
E = ( 2, -6 )
3 x (-6) = 2 x 2 - 1
-18 = 4 - 1
-18 ≠ 3
Thus the point C = ( 2, 1 ) lies on the line 3y = 2x - 1.
