Answer: B.20
Step 1: Understand the graph
In the graph provided, each line goes up by 10 on the y-axis, with the graph marking each 50. On the x-axis, every 5 lines is equal to 1, as indicated on the graph.
Step 2: Find the unit rate
To find the unit rate, we need to find where the line hits 1 on the x-axis. To do so, go to one on the x-axis, and go up until you find where the line hits. Then we see the value on the y-axis to know the unit rate. In this case, it is on the second line above. Since we established in step 1 that each line is equal to 10 on the y-axis, we know that the two lines will be equal to 20.
This is your answer! The unit rate is 20. Hope this helps! Comment below for more questions.
Answer:
A
Step-by-step explanation:
Alright, this may come out weird on computer, but here we go.
First, you want to change this into a multiplication problem, with Keep change flip. So now it's (c^2-c-20/c^2-6c+5) * (3c-3/c^2-16). You then want to simplify some number down.
You can simplify the first part using the X game (not sure if you know this), but you put the c value at the top, and the B value at the bottom, and the two sides blank. These two values must add to equal the C value, but multiply to equal the B value, so you get -5 and 4 for the numerator of the top. Following this formula, and using difference of perfect squares, you'll end up with the following.
(c-5)(c+4)/(c-5)(c-1) * 3(c-1)/(c+4)(c-4)
You then need to cancel out your different groups, so you'll cancel out (c-5), (c+4), (c-1).
After all that, you'll end up with 3/c-4, so the answer is A.
Answer:
its just 9a+3b-5 because they arent the same.
you cant do a+b-5

Step-by-step explanation:
No, Crammer’s Rule isn’t always
applicable when trying to solve a system of linear equations because let’s say
for example, i<span>f the determinant of the coefficient matrix is 0,
then Cramer's rule cannot be applied. This
usually happens there’s no solution or an infinite number of solutions. </span><span>In
linear algebra, </span>Cramer's rule<span> is
an explicit formula for the solution of a system of linear equations with as
many equations as unknowns, valid whenever the system has a unique solution.</span>
