Jerry read 12 hours or 60/5 in those 20 days but I cant tell you how much in September.
The axis of symmetry of h(x) = 5x2 + 40x + 64 = -4
The formula for calculating the axis of symmetry is expressed as:
Axis of symmetry x = -b/2a
h(x) = 5x^2 + 40x + 64
a = 5 and b = 40
Answer:
What i got was 3000 please mark wrong if it not right
Step-by-step explanation:
{-2x + 7y = -5
{-2x - 4y = 6 | · (-1)
{-2x + 7y = -5
{2x + 4y = -6 (+)
----------------------------------
-2x + 2x + 7y + 4y = -5 + (-6)
11y = -11 | : 11
y = -1
{y = -1
{2x + 4y = -6
{y = -1
{2x + 4 · (-1) = -6
{y = -1
{2x - 4 = -6 | + 4
{y = -1
{2x = -2 | : 2
{y = -1
{x = -1
Perimeter=4h+4
If the base is 2 more than the height, it gives us the equation:
b=h+2
The equation for the perimeter of a rectangle can be though of as 2b+2h, so substituting in (h+2) for b from the first equation, we get 2(h+2)+2h.
This can be simplified to be 2h+4+2h or 4h+4
