Find the x- and y-intercept of the line. –3x + 9y = 18

1 answer:

4 0

Line –3x + 9y = 18

x-intercept when y = 0
so -3x = 18
x = -6

y-intercept when x = 0
so 9y = 18
y = 2

answer
x-intercept (-6,0)
y-intercept (0, 2)

hope it helps

I already answered that question, here's the link: brainly.com/question/10534199.

But if you still want the explanation, here it is:

"So if we want to measure probability, you have to add, then divide, like this:

First $4+8+6$ , which gives us 18.

Then we see, that 6 is 1/3 of 18, so we conclude. The answer is 33.33%.

Hope this helped!"

Geometry Help Please!!! See Picture Below

MArishka [77]

Answer:

2. RS = ST, Reason: Midpoint of a line (definition)

4. RS = XY, Reason: Transitive Property of congruence (if a=b, and b=c, a=c)

Step-by-step explanation:

A Midpoint divides a line exactly in half, due to the definition of a Midpoint. So, RS = ST, since they measure the same distance from the Midpoint. RS=XY because of the Transitive Property of Congruence. If ST = XY, and RS = ST, then RS = XY.

Michael has a recipe that requires 3/4 cup of flour,and he wants to make 1/2 the recipe. How much flour does he need?

Eva8 [605]

Answer:

Michael will use 3/8 cup of flour.

Step-by-step explanation:

Half of a Fraction:

1. Reduce fraction to its lowest terms.

2. If the numerator is an even number than divide the numerator by 2.

Example: 4/5 divided in half would be 2/5.

3. If the numerator is an odd number than multiply the denominator by 2.

Example: 1/3 divided in half would be 1/6.

3/4 cup of flour divided in half would be 3/8 because the numerator 3 is an odd number so the denominator of 4 would be multiplied by 2 equaling 8.

Find the density of a 40 gram pyramid with rectangular base 5 x 6 cm and height 8 cm.

e-lub [12.9K]

Density is mass
volume
With those dimensions, the volume of the pyramid is;
V = lw(h/3)
V = (5)(6)(8/3)
V = 80 cm^3

D = 40 g = 1 g/cm^3
80 cm^3

Answer:

a) Total Cost for EzRecords = $13000

Cost per unit of EzRecords = $162.50

Total Cost for ProOffice = $10000

cost per unit of ProOffice = $200.00

b) Total Cost for EzRecords = $25000

Cost per unit of EzRecords = $125.00

Total Cost for ProOffice = $17500

cost per unit of ProOffice = $175.00

Step-by-step explanation:

a) Total Cost = Fixed Cost + Variable Cost

Fixed Cost = $7500

Variable Cost = cost of making a unit of output × number of units produced.

Variable Cost of EzRecords products = $100 × 80 = $8000

Variable Cost of proOffice products = $150 × 50 = $7500

Fixed Cost for EzRecords = (20/30) × 7500 = $5000

Fixed Cost for ProOffice = (10/30) × 7500 = $2500

Variable cost for EzRecords = $8000

Variable cost for ProOffice = $7500

Total cost for EzRecords = Fixed Cost + Variable Cost = $5000 + $8000 = $13000

Total Cost for ProOffice = $2500 + $7500 = $10000

Cost per unit for EzRecords = (total cost of production)/(total units produced) = 13000/(80) = $162.50

Cost per unit of ProOffice = 10000/50 = $200.00

b) Total Cost = Fixed Cost + Variable Cost

Fixed Cost = $7500

Variable Cost = cost of making a unit of output × number of units produced.

Variable Cost of EzRecords products = $100 × 200 = $20000

Variable Cost of proOffice products = $150 × 100 = $15000

Fixed Cost for EzRecords = (20/30) × 7500 = $5000

Fixed Cost for ProOffice = (10/30) × 7500 = $2500

Variable cost for EzRecords = $20000

Variable cost for ProOffice = $15000

Total cost for EzRecords = Fixed Cost + Variable Cost = $5000 + $20000 = $25000

Total Cost for ProOffice = $2500 + $15000 = $17500

Cost per unit for EzRecords = (total cost of production)/(total units produced) = 25000/(200) = $125.00

Cost per unit of ProOffice = 17500/100 = $175.00
