The correct answer is 20.
square root 2 times square root of 200 = square root of 400 ans since 400 is a perfect square, then I'll calculate to 20.
Answer:
The answer to your question is: both lines are the same.
Step-by-step explanation:
3x + 3y = 10
-9x -9y = -30
Elimination method
9x + 9x = 30
-9x - 9y = -30
0 0 0
Answer: Option D
D. 
; 
Step-by-step explanation:
We know that the cost of preschool is $ 45 per day plus a monthly fee of $ 70.
We also know that a total of $ 880 was paid last month
To write an equation that represents this situation, let us call "d" the number of days that Barry attends school
So the cost was:
Now we solve the equation for the variable d
Therefore answer is the option D
Answer:
15/17
Step-by-step explanation:
SOH-CAH-TOA
Sine is the ratio of the length of the side opposite to the angle to the hypotenuse of the right triangle.
We are given rule
when
input is (x,y)
then output is (x+7 , y-3)
(A)
we are given
input is (-10,0)
so, x=-10 and y=0
now, we can find output
x+7=-10+7=-3
y-3=0-3=-3
so, output is (-3,-3)
(B)
we are given
input is (-7,3)
so, x=-7 and y=3
now, we can find output
x+7=-7+7=0
y-3=3-3=0
so, output is (0,0)
(C)
We know that
x+7 and y-3 are translation rules of function
so, this is function
