My best guess is add all of the numbers together then divide by 6 then check your choices to see if your response matches
Step-by-step explanation:
y is directly proportional to x^2.
This means that y = kx^2, where k is a real constant.
When x = 7, y = 245:
245 = k(7)^2 = 49k. By division, k = 5.
Now we know that y = 5x^2, when x = 9, y = 5(9)^2 = 5 * 81 = 405.
Answer:
u(x) and v(x) 2
Step-by-step explanation:
(Strictly speaking of domain):
u(x) has the same restrictions as v(x).
In v(x) it can be anything except 2. Its restriction is 2.
In u(x) it can be anything except for v(x)'s restrictions. Its restriction is also 2.
Answer:
y=2x+2
Step-by-step explanation:
The equation will be y=2x+b. Note the slope is 2, since this line is parallel to y=2x+14.
Substitute (2,6) in it and we get 6=2(2)+b
6=4+b
b=2
So y=2x+2
First, lets convert our dimensions into cm.
2*2.54 = 5.08 cm.
1.5*2.54 = 3.81 cm.
Now, lets multiply by for the get the dimensions of the original painting in inches.
5.08*40 = 203.2 cm
3.81*40 = 152.4 cm
Finally, lets divide our new dimensions.
203.2/2.54 = 80 in.
152.4/2.54 = 60 in.
The dimensions of the original painting is 80 in. by 60 in.
