y-intercept =
Answers
Answer:
Slope = -1/4
y-intercept = 8
Step-by-step explanation:
Given a line equation, x + 4y = 32
To get the slope and y-intercept from this equation, we shall represent it in the slope form of a line equation
The slope form of a line equation is given as
y = mx + c
Where;
m = slope
c = y-intercept
Step 1
x + 4y = 32
Subtract x from both sides of the equation
x + 4y - x = -x + 32
4y = -x + 32
Step 2
Divide both sides by 4 to make y subject
4y/4 = -x/4 + 32/4
y = -x/4 + 8
y = (-1/4)x + 8
This equation corresponds to
y = mx + c
m = -1/4
c = 8
Therefore, the slope, m = -1/4
The y-intercept, c = 8
Intercept c=8

A candy company packages caramel into containers that hold 32 fluid ounces. In the last batch, 1,848 fluid ounces of caramel were made. How many containers were needed for this batch?
Answers
Answer:
The discount is 15% because 6/40 = 0.15 and a percent is multiplied by 100 so the answer is 15%.
Final answer:
To find the percentage discount, subtract the discount amount from the original price and divide by the original price, then multiply by 100.
Explanation:
To find the percentage discount, we need to calculate the amount of the discount first. The discount is given as $6, so we subtract $6 from the original price of $40 to get $34. To find the percentage, we divide the discount amount by the original price and multiply by 100. In this case, the discount percentage would be (6/40) * 100 = 15%.

9.7 rounded to 10
Step-by-step explanation:
I'm pretty sure 10 would be the answer, because since they are similar triangle you would cross multiply. So you would do , you would the cross multiply 23×17 and 40×X. You would then have 40X=391, so you would divide 391÷40, so X=9.7 or 10

Answer:
Step-by-step explanation:
X² + 10x = -8
add to both side the square of half the coefficient of X which is 5²
X² + 10x + (10/2)² = -8 + (10/2)²
X² + 5² = -8 + 5²
( X + 5 )² = -8 + 25
(X + 5)² = 17
X + 5 = +- √17
Therefore, X = -5 +- √17.
X = -5 + √17 , -5 - √17.
