Step-by-step explanation:
I am not sure what your problem here is.
you understand the inequality signs ?
anyway, to get
6×f(-2) + 3×g(1)
we can calculate every part of the expression separately, and then combine all the results into one final result.
f(-2)
we look at the definition.
into what category is -2 falling ? the one with x<-2, or the one with x>=-2 ?
is -2 < -2 ? no.
is -2 >= -2 ? yes, because -2 = -2. therefore, it is also >= -2.
so, we have to use
1/3 x³
for x = -2 that is
1/3 × (-2)³ = 1/3 × -8 = -8/3
g(1)
again, we look at the definition.
into what category is 1 falling ? the one with x > 2 ? or the one with x <= 1 ?
is 1 > 2 ? no.
is 1 <= 1 ? yes, because 1=1. therefore it is also <= 1.
so we have to use
2×|x - 1| + 3
for x = 1 we get
2×0 + 3 = 3
6×f(-2) = 6 × -8/3 = 2× -8 = -16
3×g(1) = 3× 3 = 9
and so in total we get
6×f(-2) + 3×g(1) = -16 + 9 = -7
A = cost of 1 drink $12.75 + 4a $12.75 + $12.00 = $24.75
Answer:
3
Step-by-step explanation:
The assumed frequency of defects is 2/16.
When we apply this rate to 24, (2/16)*24, we get 3.
Therefore, we can assume around 3 defective boxes tomorrow.
Answer:” use
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal
Let x be the fluid ounces of milk does Monica use.
As per the statement:
Monica uses 3 tablespoons of milk in her custard recipe.
It is also given that:
The ratio of tablespoons to fluid ounces is 2 : 1.
by proportion definition we have;
by cross multiply we have;
3 = 2x
Divide both sides by 2 we have;
therefore, fluid ounces of milk does Monica use.”

Answer:
8
Step-by-step explanation:
so my school uses the method called kcf (keep change flip)
keep the 4
change the division sign to a multiplication sign
flip 1/2 to 2/1
4x2=8
