Which of the following statements uses the multiplicative identity?
(-8)(1) = -8
-8 + 0 = -8

Answer:
(-8)(1) = -8
Step-by-step explanation:
The multiplicative identity element is 1. Multiplying by 1 does not change the value. This is illustrated by ...
(-8)(1) = -8
A school conducts 27 tests in 36 weeks. Assume the school conducts tests at a constant rate. What is the slope of the line that represents the number of tests on the y-axis and the time in weeks on the x-axis?
Answer:
The slope is equal to [tex]\frac{3}{4}[/tex].
Step-by-step explanation:
In order to solve this question we need to know that.......
[tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} }[/tex]
Where "m" = slope," [tex]y_{2}-y_{1}[/tex]" = first difference, and [tex]x_{2} - x_{1}[/tex] is the difference of the x values of the two points that we chose to fid the slope.
(If you don't understand something I would recommend to read about first differences and how we can use the first differences to find the slope).
Now we need to find two points on the line. One of them is already given to us and it is (36,27). In order to find the second one we will have to find a point with "x" and "y" values that have the same relation ship to each other as the point (36,27). We can do that by doing the following
[tex]\frac{x/a}{y/a} =\frac{x_{1} }{y_{1} }[/tex]
In this case a any common factor of "x" and "y" except 1. So now we can do the following...
[tex]\frac{36}{27} = \frac{36/9}{27/9} = \frac{4}{3}[/tex]
Now we know that another point on this line is (4,3).
Now all we have to imagine (36,27) as ([tex]x_{2} ,y_{2}[/tex]), and imagine (4,3) as [tex](x_{1} , y_{1})[/tex]. so now......
[tex]m = \frac{y_{2}-y_{1} }{x_{2} - x_{1} } = \frac{27 - 3}{36-4} = \frac{24}{32} = \frac{3}{4}[/tex]

HELP PLEASE!!!!!!!!!!!!
Answer:
y = 3x-5
Step-by-step explanation:
The difference between each y for each change of 1 in x is 3, so it's y-intercept is -5, and its slope is 3.

Bella earned $216 in interest after 4 years on a principal of $1,500. What is her interest rate?
Answer:
R = 148.6111%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/4)((1500/216) - 1) = 1.48611111
r = 1.48611111
Converting r decimal to R a percentage
R = 1.48611111 * 100 = 148.6111%/year
The interest rate required to get a total amount, principal plus interest, of $1,500.00 from simple interest on a principal of $216.00 over 4 years is 148.6111% per year.
Answer: 3%
Step-by-step explanation:
216 / 1500 = 14.4
14.4/ 48 months = .003
.003 x 100 = 3%

C.-7/3
D.7/3
ALSO PLEASE SAY HOW I NEED TO EXPLAIN HOW ITS EQUIVALENT
Answer:
A
Step-by-step explanation:
It is equivalent because as along as only one has the negative sign, then it will still be negative. Both being negative makes it positive and flipping the fraction changes the value.
Answer:
A
Step-by-step explanation:
the negative sign is exchangeable between the denominator and numerator because positive multiplied or divided by a negative will aways be a negative
