Answer:
A
Step-by-step explanation:
The gym membership is going to cost 40 initially plus 22.50 for each month after.
The total cost for the gym can be expressed as 40+22.50m
The martial arts class is going to cost 26 initially plus 16 for each month after.
The total cost for the martial arts class can be expressed as 26+16m
Now we have to combine these to get the total cost for both the gym and the martial arts class:
(40+22.50m) + (26+16m) = 66 + 38.50m (option A)
Answer:
<em><u>x=9, y=12</u></em>
Step-by-step explanation:
-5x+4y=3
--------A
x=2y-15----------B
Putting the value of x from B in A
-5(2y-15) +4y=3
-10y+75+4y=3
-6y=3-72
-6y=-72
y=72/6= 12
Putting the value of y =12 in B
x= 2(12)-15
x= 24-15
x=9
Answer:
Step-by-step explanation:
JUST HERE FOR THE POINTS
The domain is the value of x, the range is the value of y.
A parabola opens infinitely to the right and left, so x can be any number, the domain is all real numbers
Vertically, however, a parabola opens only one way, either upward or downward. when it opens upward from a a certain level, say, the lower point (the vertex) has a y coordinate of 2, we say the range is all real numbers larger than or equal to 2, or y≥2. When it opens downward, we say the range is all real numbers smaller or equal to 2, y≤2
All the rectangle are square if length becomes equal to breath !
