The answer to your question is point
To find the range, you need to locate the vertex:
equation for vertex = ax^2 + bx +c
in x^2 + 3, a = 1, b = 0 and c = 3
now vertex form = a(x+d)^2 +e
d = b/2a = 0/2*1 = 0
e = c-b^2/4a = 3-0^2/4*1 = 3
The equation becomes: (x+0)^2 +3.
The range is Y ≥ 3 ( greater than or equal to 3)
65:160 because you add all the golf balls together (including blue) and get a total of 160 and then compaire that to 65
Hello!
Here is the formula for finding slope:
<span><u>y₂ - y₁
</u>x</span>₂ - x₁
OR
<u>difference in y</u>
difference in x
_______________________________________________________
y₂ = 8
y₁ = 10
8 - 10 =
-2x₂ = 5
x₁ = 2
5 - 2 =
3That equals: -2/3
Answer:
Step-by-step explanation:
1.
(im gonna use x as a variable for all of these problems)
first to find how much each square foot costs subtract 80 from the total first
287 - 80 = 207
then divide $207 between 60 square feet
207 / 60 = $3.45
so each square foot is $3.45
our equation to find the cost would be
y = 3.45x + 80
2.
first lets find out how much the scarves are
5 x 12 = $60
then subtract that from the total
125 - 60 = $65
for 5 sister to each have 2 pairs of socks that means theres 10 pairs of socks
divide ypur rmaining money by the 10 pairs
65 / 10 = $6.50
so each pair of socks is $6.50
3.
first lets make an equation for the ymca costs
y = 15x + 20
then plug in 185 for y
185 = 15x + 20
solve for x
165 = 15x
11 = x
