Answer:
1 and 2
Step-by-step explanation:
Zeros of the function is where the function intersect with x-axis (or in other way the zeros of function is x value when y = 0 )
y=x^2-3x+2
(we substitute y with zero)
0 = x^2-3x+2
or in other way
x^2-3x+2 = 0
Then we factor out the function by using the grouping method
(When we should give two numbers that there sum is equal -3 and if we multiply them we get 2)
and these two numbers are -2 and -1
x^2-3x+2 = 0
*Substitute the middle term with -x-2x
x^2-x-2x+2 = 0
*factor out x , then factor out -2
x(x-1)-2(x-1) = 0
*factor out x-2
(x-2)(x-1)=0
Either
x-2 = 0
So
x = 2
Or
x-1 = 0
So
x = 1
in conclusion the zeros of this function is 1,2
Anna= a
Vickie= v
Luanna= l
a is 3 years older that v
l is 2 years younger than v
Anna's age; 3+v
Luanna's age; v-2
The equation to represent the amount of apple left is 20 - ( 8 + 6 + 3 ) pounds.
<u>Explanation:</u>
Number of apples = 20 pounds
2 batches of apple sauce uses 4 pounds each of apples
So,
amount of apples used in apple sauce = 2 X 4 pounds
= 8 pounds
1 batch of apple butter uses 6 pounds of apples
Apple juice requires 3 pounds of apples
Amount of apple left = 20 - ( 8 + 6 + 3 ) pounds
= 3 pounds
Amount of apple left is 3 pounds
Therefore, the equation to represent the amount of apple left is 20 - ( 8 + 6 + 3 ) pounds.
