Answer:
D.
Step-by-step explanation:
Because in negative numbers greater is actually less
Answer:
change into improper fraction , find the common multiple and choose from the biggest because it is a negative fraction
-6x + 2y = 2
Answer:
x = 2, y =7
Step-by-step explanation:
4x - 2y = -6
-6x + 2y = 2
Add the equations together
4x - 2y = -6
-6x + 2y = 2
-----------------------
-2x = -4
Divide each side by -2
-2x/-2 = -4/-2
x = 2
now find y
-6x+2y =2
-6(2) +2y =2
-12+2y =2
Add 12 to each side
-12+12+2y = 2+12
2y =14
Divide by 2
2y/2 =14/2
y =7

What is the frosted area of the bottom cake? (Round to the nearest tenth)
What is the total surface area of cake that will be frosted?
Answer:
$22.5.
Step-by-step explanation:
The total revenue that is gained from the sales of the cakes is determined by multiplying the number of cakes by the price. If we let x be the number of $1 that should be deducted from the price and y be the total revenue,
y = (25 - x)(100 + 5x)
Simplifying,
y = 2500 + 25x - 5x²
We get the value of x that will give us the maximum revenue by differentiating the equation and equating the differential to zero.
dy/dx = 0 = 25 - 10x

at point M. Find the area of ΔBDM. What is the area of ABCD?
The diagram is attached below
The midpoint of AC is E. The ΔMAE is congruent to ΔBCE, and the sides MA = BC = 5 cm. Also MD = 17 -5 = 12 cm
From the figure we can see that the height of the trapezoid is 8cm
The height of trapezoid is the difference between the x axis and the BC that is 8cm
The triangle BDM has base 12 cm and height 8 cm.
Area of triangle =
A = = 48 cm²
2. The area of trapezoid ABCD formula is
A =
base 1= 17cm , base2= 5cm , height = 8cm
A =
A = 88 cm²
