Answer:
30
Step-by-step explanation:
The full pie chart will equal 100%
So we can add all the percentages together and then subtract that percentage from 100 and whatever's left is the parentage that they attend school.
12+3+5+10+5+35
70
100-70
30
They spend 30% attending school

Answer:
1/2x
Step-by-step explanation:
To solve this type of fraction you need to times the inverse of the bottom fractal, both over and under. In this case the inverse of 1/2 is 2/1
Step-by-step explanation:
f(x)=4x+3. f(x)=27
so 27=4x+3
27-3 =4x
24=4x
x=24/4
x=6
Answer:
(-2 , 5)
(-1 , 0)
(1 , -4)
(3 , 0)
(4 , -5)
Step-by-step explanation:
<u>First solve the equation:</u>
x² - 2x - 3
<em><u>Find two numbers with have a sum of -2 and a product of -3.</u></em>
-3 and 1
(x - 3)(x + 1)
Solve for x:
x - 3 = 0
x = 3
x + 1 = 0
x = -1
You know that the graph will cross the x-axis at -1 and 3.
(-1 , 0)
(3 , 0)
You know that the graph is positive.
<u>Complete the square to find the vertex</u>
x² - 2x - 3
(x - 1)² = x² - 2 + 1
x² - 2x - 3 = x² - 2 + 1 - 2 = (x - 1)² - 2
1 = 0
x = 1
Substitute into the original equation:
x² - 2x - 3 =
1² - (2 * 1) - 3 =
1 - 2 - 3 =
-4
(1 , -4)
<em><u>You can input any two numbers within -10 and 10. Such as -2 and 4.</u></em>
x² - 2x - 3 =
-2² - (2 * -2) - 3 =
4- -4- 3 =
5
(-2 , 5)
x² - 2x - 3 =
4² - (2 * 4) - 3 =
16 - 8 - 3 =
-5
(4 , -5)
