Divide 3 1/2 by 2/3.
3 1/2 = 7/2 as an improper fraction, so we have
7/2 ÷ 2/3
= 7/2 * 3/2
= 21/4 = 5 1/4 L
Answer:
Step-by-step explanation:
for the square, it's got 4 sides so
4(5x) = 5x + 4x+14 +5x + 4
20x = 14x +18
6x = 18
x = 3
answer D looks good
(-11,-3) (-6,7)
7+3/-6+11= 10/-5
Slope is -2
Answer:
y = (x + 4.5)² - 13.25
Step-by-step explanation:
y = x² + 9x + 7
We need to get a perfectly squared binomial as part of the right side.
Take the '9x' term, divide it in half, square it, add <u>and also subtract it </u>on the right side, as shown below. That would be (4.5)² = 20.25 added <u>and </u>subtracted.
y = x² + 9x + 7
y = x² + 9x + 20.25 + 7 - 20.25
y = (x² + 9x + 20.25) - 13.25
y = (x + 4.5)² - 13.25
y = (x + 4.5)² - 13.25
Vertex Form is y = a(x-h)² + k, where the parabola vertex is (h, k)
So if you wrote this as y = 1(x - [-4.5] )² + (-13.25), we would see that a = 1, and h = -4.5 and k = -13.25.
Vertex = (-4.5, -13.25)
I verified on a graphing calculator that this is indeed the vertex of the parabola.
Hello!
The scale factor is what the first item was multiplied by to get the second item
there are 12 inches in a foot
Because of the the answer is 1/12
the answer is 1/12
Hope this helps!
