Standard Form : f (x) = a(x - h)2 + k
Where in this equation (H,K) is the vortex of the parabola
<u>and there are four other ways to solving these quadratic</u>
1. Factoring
2. Completing the square
3. Your quadratic formula ( f (x) = a(x - h)2 + k )
4. Graphing
Answer:
see below
Step-by-step explanation:
x+ 7.05 = 45.3
Subtract 7.05 from each side
x+ 7.05-7.05 = 45.3-7.05
x =38.25
Let x be the number
x+3.5 = -4.3
Subtract 3.5 from each side
x+3.5 - 3.5 = -4.3-3.5
x = -7.8
x is the cost of the drawing tablet
x+ 3.95 = 6.94 correct
The second equation add the total cost plus the cost of the drawing tablet and sets it equal to the cost of the pencils. This is not correct
6.94+x = 3.95 incorrect
Answer:
2^10 = 1024
Step-by-step explanation:
The test most likely can be answered in two different ways. the different ways that 10 questions can be answered will be:
2^10 = 1024
One gallon is equivalent to 128 fluid ounces
3 gallons is equivalent to 3*128 fluid ounces
= 384 fluid ounces
One plastic cup can hold 12 guide ounces
So cups needed will be 384/12
32 cups
Let U be the universal set, where U=(1,2,3,4,5,6,7,8,9)let sets A and B. be subsets of U, whereA=(2,3,8,9) and B=(1,2,3,5)

(A U B) = {1, 2, 3, 5, 8, 9}
(A U B)^c = {4, 6, 7}
A^c = {1, 4, 5, 6, 7 }
B^c = {4, 6, 7, 8, 9}
A^c ∩ B^c = {4, 6, 7}
8 + 3(4 + 5)
8 + 3(9)
8 + 27 = 35
