1. Exponents are the repeated multiplication of a number. It is represented
by the formula of a^n where a is the number to be repeated and n is the number
of times the number is being multiplies by itself. Also include the sign of the
number, no matter how it is multiplied, it is still important. For instance you have 4(4),
you have 4 as the repeated number. You can see that it is multiplied by itself
by two times. So you have (-4)^2.
2. Graphs and tables are the key features in finding a model between two quantities. If he data values, after plotting it into a graph, produces a straight line, then you will have a direct relationship between the two and sometimes you can get an equation of the line. Sometimes it will give you a curved line. That is why it is important to graph the values of the table to better understand the relationship between two variables.
Answer:
94 pizzas will be sold
Step-by-step explanation:
We have to use the equation and replace 15 with x.
x=15
y=3.4x + 43
y=3.4(15) + 43
y=51 + 43
y=94
(15,94)
There will be 94 pizzas sold nightly if 15 coupons were issued.
From the steps shown in the table given, we can conclude that: D. in solving the equation, the subtraction property of equality was not applied.
<h3>What is the Subtraction Property of Equality?</h3>
If a + b = c, to apply the subtraction property of equality so that b is moved to the other side of the equation, we would have:
a + b - b = c - b
a = c - b
Thus, from the table given, the none of the steps showed that the subtraction property of equality was applied in solving the equation, so, the answer is: D.

Answer:
100C=m
Step-by-step explanation:
If 250 copies are made in 2.5 minutes, you get the equation:
250c=2.5m
divide by 2.5 on both sides and you get:
100c=m
So in m minutes, 100c copies are made.
I believe it is x = 2f
