Answer:
y=7.5x, y=60
Step-by-step explanation:
you have to consider x as the input and y as output
when input x=2 the output y=15 so it grew by 7.5 so we can say that y= 2*7.5
in general the equation is y= 7.5*x
when x=8 we will have y=7.5*8=60

Sum of the interior angles of any triangle is 180° .
Thus ;
[tex]y + 48° + 90° = 180°[/tex]
[tex]y + 138° = 180°[/tex]
Subtract sides 138°
[tex]y + 138° - 138° = 180° - 138° \\ [/tex]
[tex]y = 42°[/tex]

You and a friend are doing math homework together you have to solve the equation 5X + 4X -68 equals 34 - 8X. Your friend arrives at the incorrect answer X equals -2 find the correct value of X then find the error your friend possibly be made
Answer:
the correct answer
x = 6
Step-by-step explanation:
5x+4x-68=34-8x, combine like terms
9x-68=34-8x, add 68 to both sides
9x=102-8x, add 8x to both sides
17x=102, divide both sides by 17
x=6
your friend's answer is the same work, but instead of adding 68 to both sides, it was subtracted from 34 giving a -34 instead of 102.
9x=-34-8x
17x= -34
x = -2

Use any method to multiply (–14ab)(a + 3b – 4c).
Question 2 options:
A)
–14a2b – 42ab2 + 56c2
B)
14a2b + 42ab2 + 56abc
C)
–14a2b – 42ab2 + 56abc
D)
–14a2b – 42a2b2 + 56c
Answer:
-14 a^2 b - 42 a b^2 + 56 a b c C. is the answer
Step-by-step explanation:
Expand the following:
-14 a b (a + 3 b - 4 c)
Hint: | Distribute -14 a b over a + 3 b - 4 c.
-14 a b (a + 3 b - 4 c) = -14 a b a - 14 a b×3 b - 14 a b (-4 c):
-14 a b a - 14×3 a b b - 14 (-4) a b c
Hint: | Combine products of like terms.
-14 a b a = -14 a^2 b:
-14 a^2 b - 14×3 a b b - 14 (-4) a b c
Hint: | Combine products of like terms.
-14 a b×3 b = -14 a b^2×3:
-14 a^2 b + -14×3 a b^2 - 14 (-4) a b c
Hint: | Multiply -14 and 3 together.
-14×3 = -42:
-14 a^2 b + -42 a b^2 - 14 (-4) a b c
Hint: | Multiply -14 and -4 together.
-14 (-4) = 56:
Answer: -14 a^2 b - 42 a b^2 + 56 a b c
Brodie hires a technician to fix his air conditioning unit. The total cost includes $26.50 for parts and $50.00 per hour the technician works on the job.
Which equation can be used to find y, the total cost Brodie pays, given x represents the number of hours the technician works on the job?
y = 26.50x + 50
y = 50x + 26.50
y=26.50(x+50)
y=26.50x−50
Answer:
y = 50x + 26.50
Answer:
Y = $50x + $26.50
Step-by-step explanation:
$26.50 is the independent cost unaffected by hours put in.
Rate is $50 per hour.
X then is the hour count.
Thus,
Y = $50x + $26.50
A rectangle has a perimeter of 104 feet. If the
width of the rectangle is one more than twice its
length, determine the dimensions of the
rectangle.
Answer:
w=35, L = 17
Step-by-step explanation:
the perimeter is all sides added together to total 104. so,
2L + 2W= 104
the width is one more than twice it's length, so W = 2L + 1
plug that into first equation.
2L + 2(2L+1)=104
distribute:. 2L + 4L + 2= 104 and continue to solve for L
6L + 2= 104 subtract 2 from both sides.
6L = 102, divide both sides by 6
L = 17. so the length is 17 ft. now use that number to put it in our equation for width, W= 2L + 1
W= 2(17)+1
W = 35

The product of a number and negative three is twenty-seven. Which of the following could represent this statement?
-3n + 27
-3(27) = n
-3n = 27
-3 = 27n
Answer:
-3n=27
Step-by-step explanation:
The value of n is -9.
So we can represent this in an equation. We won't get that as a result if we multiply the following
-3n=27 Divide -3 by both sides.
n=-9
Answer:
The product of a number and negative three is twenty-seven.
-3n=27

Answer:
A, B, C, D, F . . . as written
Step-by-step explanation:
Any mixed number, fraction, or finite or repeating decimal is rational. The only one in your list that is irrational is E, which appears to be a non-repeating, non-terminating decimal.
__
Your B selection appears to be 11² = 121, an integer and a rational number.
If your B selection is supposed to be √11, then that number is irrational, as it is not the root of a perfect square.
E is irrational; B is rational as written, but irrational if it should be √11. All the others are rational.

At the end of the year, cars made in the current year are marked down to make room for next year's models. One particular model had a sticker price of $22,570 when it was new. It has just been marked down by 10%. What is the sale price of the vehicle?
Answer:
$20,313
Step-by-step explanation:
You're only reducing 10% of the cost so first you need to figure out what 10% of $22,570.
All you need to do is
22570×0.1=2,257
and then
22,570-2,257=20,313
There is other ways to do this but this is how I do it. Hope this helps!
