Answer:
35 pies
Step-by-step explanation:
17 + 18 = 35 pies
18 cups of sugar = 18 pies
Answer:
n = 6
Step-by-step explanation:
2n - 32 = 10n - 80
2n - 10n = -80 + 32
-8n = -48
-48/-8 = 6
1. Simplify 0.24 x 14.3 to 3.432.
= 3.432 ÷ 5.2
2. Simplify 3.432 ÷ 5.2 to 0.66.
= 0.66
Answer:
(-b/2a, b^2/(4*a) - b^2/2a + c)
Step-by-step explanation:
For a general parabola:
y = a*x^2 + b*x + c
We can write the vertex as:
(h, k)
The x-value of the vertex is the value of the axis of symmetry.
Then we have:
h = x = -b/2a
Now we need to find the y-value of the vertex.
To do that, we just replace the variable "x" by the x-value of the vertex in our equation, so we get:
k = y = a*(-b/2a)^2 + b*(-b/2a) + c
k = b^2/(4*a) - b^2/2a + c
Then the coordinates of the vertex are:
(h, k) = (-b/2a, b^2/(4*a) - b^2/2a + c)
Answer:
y = x + 3
Step-by-step explanation:
The equation of a line is y=mx + b, where m is the slope and b is the y-intercept.
In this case, the slope of the line is 1, and the y-intercept (the point where the line crosses the vertical axis) is 3. So you just need to plug in the 3 in place of b.
y = mx + b
m = 1
b = 3
y = x + 3
