Answer:
D. The zeros are 3 and -10, because y = (x - 3)(x + 10).
Step-by-step explanation:



Therefore, D is correct by the Zero Product Property
Answer: 6.6 miles
Step-by-step explanation:
Since he finished 22% of his skiing in the morning, that means he still has 78% (100% - 22%) of his skiing left.
The remaining 78% is equivalent to 23.4 miles. We need to know the total miles of the skiing. This will be:
78% of x = 23.4
0.78 × x = 23.4
0.78x = 23.4
x = 23.4 / 0.78
x = 30 miles
Since the total skiing is 30 miles and he has 23.4 miles left, the miles covered in the morning will be:
= 30 - 23.4
= 6.6 miles
Answer:
1:4
Step-by-step explanation:
If 8/10 prefer Crest, that means 2/10 don't prefer it.
To find the ratio, put together the number that don't prefer it to the number that does:
2:8
Simplify by dividing each side by 2:
1:4
So, the ratio is 1:4
Answer:
y = 63
Step-by-step explanation:
A straight line is equal to 180 degrees.
180 = 2y - 18 + y + 9
180 = 3y -9
189 = 3y
189/3
y = 63
Answer:
32
Step-by-step explanation:
x^2 + 4y = 16 + 20 = 32
Just do substitution.
Hope this helps.
Good Luck
