Which grade is this??????
ANSWER
The solution is where the two graphs intersect, which is

EXPLANATION
The given system of equations are

and

We need to graph the two equations.
Let us graph

first.
We need at least two points.
You can choose any appropriate value for x and solve for y. Choosing zero makes our working easier. So let us plot the intercepts.
When




So this gives us the ordered pair,

When

we get,




This also gives the ordered pair

We plot these two points and draw a straight line through them to obtain the blue graph in the attachment.
For the second line

We again find the intercepts and plot them.
When



This gives the ordered pair

Also, when

then we have,



Then we again have the ordered pair,

We plot these two points on the same graph sheet to obtain the red graph above.
The intersection of the two lines is

You will get good grades so don't worry much.
Direct variation should be called linear variation.
In this case, the answer is B.
A has the quadratic variation, C has the inverse variation, D has the cubic variation
Answer:
#2) is 25
Step-by-step explanation:
the best way to solve any of theses is in the order of pemdas:
●parentheses
●exponents
●multiplication & division
●addition & subtraction
for example lets do #2
9+ (2^2)(4)
the first parenthesis has exponents so you'd do it first. 2^2 (two two times) is 4
9+(4)(4)
when two parentheses are next to Each other you multiply. 4x4 is 16
9+16
then finally you add
25
use these steps for the rest. just comment if you have any questions
