The correct answer should be D
Divide total grams by 28.35 to get ounces:
226.8 / 28.35 = 8 ounces
Divide cost by ounces:
14.99 / 8 = 1.87
ANSWER: C. $1.87
<span>1, 2, 3, 6, 9, and 18</span>
Answer:
C.
Step-by-step explanation:
The transformation f(x) ---> a f(x) stretches the graph of f(x) vertically by a factor a.
The point (1, 1) on f(x) transforms to (1,9) on g(x).
This is a vertical transformation of factor 9, so g(x) = 9f(x)
= 9x^2 or (3x)^2.
Answer:
-7 or 4
Step-by-step explanation:
use foil to get the quadratic equation:
x^2+5x-2x-10=18
x^2+3x-10=18
bring "18" to the left:
x^2+3x-10-18
x^2+3x-28
so what*what= -28
and
what+what=3
factors of -28: -7,4 -4,7 14,-2 -14,2 -28,1 -1,28
factors whose sum is 3: 7,-4
so substitute "7,-4" in place of 3:
x^2+7x-4x-28
2) split it in two groups
group 1) x^2+7x
group 2) -4x-28
x^2+7x has a GCF of "x"
x(x+7)
group 2) -4x-28 has a gcf of "-4"
-4(x+7)
3) (x-4) (x+7)=0
x-4=0
x=4
x+7=0
x=-7
x=4,-7
Hope this helps!
