The anser is C for reasons of science ;)
Answer:
answer B: (2,-2)
Step-by-step explanation:
First, write the equations on top of each other:

Then, multiply the the second equation by 2 so that we can use elimination of the y-variable:

Next, use elimination to find the value of "x":

So, your x-value is 2.
Now, substitute your x-value into one of your equations, let's take the second equation, 2x-y=6:

Your y-value is -2.
With all your information gathered, you find that the solution to this system of equation is (2,-2).
Answer:
= 45 miles per hour
Step-by-step explanation:
First, we want a unit rate where 1 is in the denominator.
So we divide,
180 miles/ 4 hours both ÷ by 4
= 45 miles/ 1 hour
= 45 miles/ hour
= 45 miles per hour
Hello!
To calculate how much 3 cakes would cost, we must first find the cost of each individual cake.
To do this, we must divide the cost of 8 cakes by 8 cakes.
4.00 ÷ 8 = 0.5
This means that each individual cake costs $0.50. Multiply this by 3 to find the cost of 3 cakes.
0.50 × 3 = 1.50
Therefore, 3 cakes would cost $1.50.
(x-15)2+ (y+35)2=2500. for sure without a doubt.
