Answer:
x=12
Step-by-step explanation:
Let y equal number of pushups a day. When x = 1, y = 8. When x = 2, y = 10. 10 is a factor of 30. Multiply y by 3. However, since x increases by 1 when y increases by 2, multiply x by 6 (2*3). That equals 12. Therefore, when x = 12, y = 30.
Answer:
h(x) = 2x² -8x -10
Step-by-step explanation:
In the US, a quadratic is in standard form when the terms are listed in order of decreasing degree.
In the UK, a quadratic is in standard form when it is written in vertex form.
__
<h3>US</h3>
The only function with terms in order of decreasing degree is ...
h(x) = 2x² -8x -10
<h3>UK</h3>
All of the functions <em>except the last</em> are written in vertex form:
- f(x) = (x +1)² +0 . . . . . . . . would usually be written f(x) = (x +1)²
- y(x) = -(x -6)² +16
- g(x) = -3(x -3)² +4

<em>Additional comment</em>
Since the question asks about <em>one</em> function, we assume it is from the perspective of the US understanding of <em>standard form</em>. The point here is that "standard form" may vary from one tradition to another. (The "standard form" for numerical values varies by tradition, as well.)

8*rad3=8rad3
8rad3/2=4rad3
4rad3*rad3=12
Answer:
a.) $10.50
b.) $45.00
c.) about 66.67%
Step-by-step explanation:
a.) regular price = 15.00
discount = 30% or 0.3
15 x 0.3 = 4.50 ----------> this is the amount that you will have off
15.00 - 4.50 ---------> by subtracting from original price, you have sale price
= $10.50
b.) bought price = 25.00
marked up = 80% or 0.8
25.00 x 0.8 = 20 -------> this will give you 80% of 25
25.00 + 20.00 ------> she sells for 80% higher, so add the numbers
= $45.00
c.) original price = 36.00
bought price = 36.00 - 12.00
= 24
24 / 36 -----> divide bought price by original to find what percentage it is
= .66666 which is rewritten as 66.667%
you can check this by multiplying that percentage by the original price
hopefully this helps a little bit
