Answer:
1.36 per pound
Step-by-step explanation:
$6.80 divided by 5 = $1.36
<u><em>Answer: x=4 *The answer should be the positive sign.*</em></u>
Step-by-step explanation:
cancel by the common factor of 6.
x/16=1/4
multiply by 16 both sides of an equation.
16x/16=1*16/4
multiply the numbers.
1*16=16
=16/4
16/4=4
x=4
Hope this helps!
Thanks!
Have a great day!
5=x
x=4
didn’t know if u needed work but here
Answer:
Step-by-step explanation:
The first parabola has vertex (-1, 0) and y-intercept (0, 1).
We plug these values into the given vertex form equation of a parabola:
y - k = a(x - h)^2 becomes
y - 0 = a(x + 1)^2
Next, we subst. the coordinates of the y-intercept (0, 1) into the above, obtaining:
1 = a(0 + 1)^2, and from this we know that a = 1. Thus, the equation of the first parabola is
y = (x + 1)^2
Second parabola: We follow essentially the same approach. Identify the vertex and the two horizontal intercepts. They are:
vertex: (1, 4)
x-intercepts: (-1, 0) and (3, 0)
Subbing these values into y - k = a(x - h)^2, we obtain:
0 - 4 = a(3 - 1)^2, or
-4 = a(2)². This yields a = -1.
Then the desired equation of the parabola is
y - 4 = -(x - 1)^2
