If 1 cup of that particular vanilla powder has a mass of 128 grams, then 
of a cup of vanilla powder has a mass of
grams.
Since
grams and 
of a cup of vanilla powder is
then correct answer is that he went over by of a cup.
Answer: correct choice is B.
Answer:
y = 4x - 5
Step-by-step explanation:
y = mx + b
By putting above values in equation (i)
-1 = 4 (1) + b
-1 = 4 + b
-5 = b
b = -5
y = 4x - 5
Answer:
The area is 78.5, the farmer does have enough space to plant his vegetables
Step-by-step explanation:
To find the area, you need to use the formula, A=πr², (make sure the diameter is turned into the radius by dividing by 2, in this case, it's 5 as the radius)
Plug in your numbers, A= 3.14(5)²
A= 3.14(25)
The area is 78.5
So the farmer does have enough space to plant his vegetables since 78.5 is greater than 25
Answer:
x = - 4 ± 2
Step-by-step explanation:
Given
f(x) = x² + 8x + 4
To find the zeros let f(x) = 0, that is
x² + 8x + 4 = 0 ( subtract 4 from both sides )
x² + 8x = - 4
To solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(4)x + 16 = - 4 + 16
(x + 4)² = 12 ( take the square root of both sides )
x + 4 = ± 
= ± 2 ( subtract 4 from both sides )
x = - 4 ± 2
Thus the zeros are
x = - 4 - 2 and x = - 4 + 2
