Answer:
B
Step-by-step explanation:
Answer:
£4 and £8.
Step-by-step explanation:
There are 3 parts to the sharing ( 2 + 1 = 3).
So one part is 1/3 of 12.
One part is 1/3 * 12 = £4
and 2 parts = 2/ * 1/3 * 12 = £8.
The first one:
5v + 3 = 5v - 5
Subtract 5v from both sides ->
3 = -5
This isn't true so that means there are no solutions...
Using the numbers in the given equation:
a =-2, b = 6 and c = -5
The vertex form is written as : a(x+d)^2 + e
we need to find d and e:
d = b/2a = 6/2(-2) = -3/2
e = c-b^2/4a = -5 - 6^2/4(-2) = -1/2
Now substitute the letters for their values in the vertex form formula above:
-2(x-3/2)^2 -1/2
The vertex is (3/2, -1/2)
2. The formula begins with a negative number ( -2) so the Parabola opens downwards.
3. To find the intercept replace x with 0 and solve for y:
the intercept is (0,-5)
Thirty-eight is 38
Ninety seven hundredths is 0.97
So the whole thing would be 38.97
