Step-by-step explanation:
She cuts 3 equal length strips of the paper, which was originally 8 ft long. This means that all we have to do is 8 divided by 3, which = 8/3. Change this fraction to proper, getting 2 and 2/3. The correct answer, therefore is A.
Which of the following is a true statement about this equation?
y = -x 2 + 3x + 2
A. The equation is a function.
B. The equation is not a function.
C. A horizontal line test would show that the equation is a relation but not a function.
D. A vertical line test would show that the equation is a relation but not a function.
Which of the following statements is false?
A. In the ordered pair (3, 7), 3 is the x-coordinate.
B. The point (0, 5) is on the y-axis.
C. The horizontal distance between the point located at (3, 7) and the point located at (6, 7) is 3 units.
D. In the ordered pair (9, 7), 7 is the x-coordinate.
Answer:
Its D, How do I know?
Step-by-step explanation:
Let's look at A. you start at zero and you go right three because x comes before y then go up 7 then you see that it says 3 is the x- coordinate so you know that is correct but you can't choose it. B and C they are really easy to identify as correct so you look at D and it's all wrong. So thats how its D.

The graph shows the the number of jars that are filled by machine A and machine B. Which statement is true about the unit rates shown in the graph?
-----------------------------------------------------------------------------------------
The unit rate for machine A is greater because the slope is greater than the slope for machine B.
The unit rate for machine B is greater because the slope is less than the slope for machine A.
The unit rate for machine A is greater because the slope is less than the slope for
machine B.
The unit rate for machine B is greater because the slope is greater than the slope for machine A.
Answer:
a
Step-by-step explanation:
a presents that the a machine is better therfore i think its a.
hope this helps
The unit rate for machine [A] is greater because the slope is greater than the slope for machine B.
What is slope?Slope of a straight line is used to define the rate of change of [y] with respect to [x].
Given are the graphs that show the the number of jars that are filled by machine A and machine B.
Slope in this case represents the number of jars filled per minute by machine A and machine B. Mathematically, we can write slope as -
m = dy/dx
Now, the ratio of [y] and [x] is equal to tanθ. So, greater the angle θ made by the line with the +x axis, greater will be its slope which in turn will represent the greater number of jars filled per minute.
It can be seen that the angle made by the straight line representing machine A makes greater angle then in the case of machine B.
So, the unit rate for machine [A] is greater.
Therefore, the unit rate for machine [A] is greater because the slope is greater than the slope for machine B.

okay so i was told to pick the ones that equal 8/12 but I'm lost
Answers:
4 to 6, 2 to 3, 8 to 12, 2:3, and 2/3.
Step-by-step explanation:
To figure out all of these ratios and figure out which are equal to 8/12, you have to:
Make all of the choices fractions
Find the least common multiple of the denominators.
(All of the answer choices have a common multiple of 12, so multiply the denominator by whatever necessary to get to 12, then multiply the same number by the numerator.)
- 4 to 6 becomes 4/6, 4/6 when you change the denominator to 12 you get 8/12. Therefore 4/6 is equal to 8/12.
- 3/2 becomes 3/2, when you change the denominator to 12 you get 18/12. Therefore 3/2 is not equal to 8/12
- 2 to 3 becomes 2/3, when you change the denominator to 12 you get 8/12. Therefore 2/3 is equal to 8/12
- 3 to 2 is the same as 3/2 so it is not equal to 8/12
- 8 to 12 is 8/12 in fraction form so it is equal to 8/12
- 3:2 is the same as 3/2, so it is not equal to 8/12
- 2:3 is the same as 2/3 and 2/3 is equal to 8/12.
- 2/3 is equal to 8/12.
- 12/8 is not equal to 8/12.
joey made a deposit into an account that earns 6% simple interest.After three years, joey had earned $400. How much was joey's initial deposit
Answer:
Step-by-step explanation:
To find the amount deposited, we will simply use the formula for calculating simple interest.
Simple Interest = pxrxt/100 (fraction)
Where p = principal
R= Rate
T= Time
Principal is the initial amount deposited which we are ask to find.
R is given to be 6% and T is the time which is given in years
Simple interest is the interest earned over the year which is given to be $400
Lets substitute our variable into the equation
Simple Interest = pxrxt/100 (fraction)
$400 = P × 6 × 3 / 100
$400 = 18p/100 (fraction)
We will then cross multiply
$40 000 = 18 P
To get the value of P, we divide both-side of the equation by 18
4000/18 = 18p/18 (fractions)
$2222.22 = P
P = $2222.22

Kenny ordered guitar strings for Glenn’s Guitar Shop. The premium guitar strings are $4.50 apiece. The standard guitar strings are $1.50 apiece. The bill smeared in the rain, but Kenny knows he ordered a total of 80 strings for $225.
Let x = the number of premium strings.
Let y = the number of standard strings.
x + y = 80,
4.50x + 1.50y = 225
How many of each type of string did Kenny order?
He ordered

SIMPLIFY these 3 expressions in TWO ways ( i know the answer i need this simplified) random answers will be reported.
Answer:
Each of these equations solves as 1, because each one of them is an instance of the same expression being divided by itself.
This will always give you a value of 1, as long as the denominator does not end up with a zero value.
Take for instance the third question:
[tex]\frac{p^4}{p^4}\\= p^4 \times p^{-4}\\= p^{(4 - 4)}\\= p^0\\= 1[/tex]
This stands true with all three questions.
HOWEVER
I say this assuming that the 5 following the first brackets in the first question is meant to be an exponent, and not a multiple. Given that the norm is to make any numeric multiples precede the brackets, I assume it is an exponent. and we're good.
It's not using superscript though, which could mean that they want it multiplied by five instead of raised to the power of.
If that's case, we can solve it the same way we solved question 20. If the bases are the same, then when multiplying or dividing the terms, you can simply add or subtract the exponents respectively:
[tex]\frac{(4x + 2y)\times5}{(4x + 2y)^5}\\= 5(4x + 2y) \times (4x + 2y)^{-5}\\= 5(4x + 2y)^1 \times (4x + 2y)^{-5}\\= 5(4x + 2y)^{1 - 5}\\= 5(4x + 2y)^{-4}\\= \frac{5}{(4x + 2y)^{4}}[/tex]
Again, this is probably not the correct answer for question 18, as that 5 is almost guaranteed to be meant as an exponent. If it is instead a coefficient though, then this would be the answer to it.
