Answer:
Step-by-step explanation:
a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying. Ex
3
(2)(9)
x
=
18
3
=
6
x=
3
18
=6
If I have to , I'll include my fractional equation with the arrows. answer is:
x = 6
Answer: D
Step-by-step explanation:
You need a calculator for this cause the numbers are really large. I used a fx-9860GII Casio calculator. I put the equations on the graph mode. And then I got the x➡️0 for both equations.
I got x=0, y=5000 for the first equation
x=0, y=5200 for the new one.
You can see the y is (5200-5000)=200 more than the old equation. As the x is 0 for both that means the new one moved 200 up for the new one. It goes up cause its positive number .
I put the pictures so you can understand what I'm saying.
Hey there!!
Given:
... A=3B+7C
Subtracting 7C on both sides:
... A-7C=3B
Dividing by B on both sides:
... (A-7C)/3=B
<em>Hope my answer helps!</em>
Answer:
<h2>C) (negative 1, one-half), (0, 1), (1, 2), (2, 4)</h2>
Step-by-step explanation:
The set C could be generated by an exponential function. The main reason is that exponential functions hava a restricted range, it can't have negative numbers or the number zero, because power can only be equal or greater than 1.
Additionally, for all exponentials, a null exponent gives 1 as an answer, so point (0, 1) is always present in an exponential function.
Therefore, the right answer is C.
