Put other y in the other equation
so u got: 4x-2=-3+5
4x-2=2
4x =4
x =1
Now put x in the equation
so u do like this: y=4(1)-2
y=2
solution is (1,2) good luck
Answer:
B
Step-by-step explanation:
So we are at C:
We need to find the dilation:
First we add 4 to x (meaning we move the point C 4 points to the right)
Then we need to subtract 10 to y (meaning we move the point C 10 points downwards)
This will give you your point:
Which is B

Answer: there are eight bicycles and 7 tricycles.
Step-by-step explanation:
Let x represent the number of bicycles that are there.
Let y represent the number of tricycles that are there.
There are a total of 15 bicycles and tricycles. This means that
x + y = 15
A bicycle has 2 wheels and a tricycle has 3 wheels. There are 37 wheels all together if we count them up. This means that
2x + 3y = 37- - - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
2(15 - y) + 3y = 37
30 - 2y + 3y = 37
- 2y + 3y = 37 - 30
y = 7
x = 15 - y = 15 - 7
x = 8
The mean is 3.25 hope this helps
4 sqrt32 + 4 sqrt48
= 4 sqrt2* sqrt16 + 4 sqrt3 * sqrt16
= 16 sqrt2 + 16sqrt3
= 16(sqrt2 + sqrt3)
