Answer: two
Step-by-step explanation:
Factor out the equation:
-2(
+ 4) = 0
-2 cannot equal zero, so that means - 4 will have to equal to zero in order to get zero as a product
- 4 = 0
Factor the equation to get:
(x+2)(x-2) = 0
x = 2, x = -2
The equation has two roots
X ----------> y
9 ----x5--->45
Namely,
2-----x5 --->y
y= 2.5 =10
Answers:
A. 1c/2lb
B. 8 cups of dressing
SOLUTION
Given that a catering company’s recipe for Salad uses a
ratio of 2c of dressing to 4 lb of vegetables
A. Write a ratio of dressing to vegetables as a reduced
fraction
A reduced fraction is the expression of a ratio in its simplest
fractional form
Dressing: Vegetable = 2c : 4 lb
In fractional form,
2c/4lb
2 is a common factor to both numerator and denominator
Therefore, in reduced fractional form,
2c/4lb = 1c/2lb
Therefore, ratio of dressing to vegetables as a reduced
fraction is 1c/2lb
B. How many cups of dressing would they need for 16 lb of
vegetables
1c = 2lb
16lb = ?
Since 1c = 2lb
2lb = 1c
1lb = 1/2 c
16lb = 16(1/2)c
16lb = 8c
Therefore, they would need 8 cups of dressing for 16 lb of
vegetables
Answer:
Step-by-step explanation:
The easiest way to tell if a relation is a function is to look at the x coordinates. If none of them are the same in the set, then the relation is a function. If any of the x values are used more than once in the set, it is only a relation. This set uses -3 two times, so it is a relation.
