Answer:

3x+2y

Step-by-step explanation:

You should first convert the plain and printed t-shirts prices into variables. I called the plain t-shirts price "x" and the printed t-shirts price "y". There are three plain t-shirts, so the price of the plain t-shirts are 3x. There are two printed t-shirts, so the price of them would be 2y. Add them and you'll get 3x+2y

Because the prices are different, you need to use two variables, one for each price.

Let the price for the plain one be X and the price for the printed one be Y.

You would multiply the number of each shirt by the variable:

3 plain would be 3X and 2 printed would be 2Y.

You then need to add those together to get the total cost:

Total cost = 3X + 2Y

Parallelogram ABCD has diagonal segments AC and BD that intersect at E. if BE is ( x + 8) and ED is (5 x), find the length of BD
Virty [35]

Answer:

BD = 20 units

Step-by-step explanation:

Given that,

Parallelogram ABCD has diagonal segments AC and BD that intersect at E.

BE = (x+8) and ED = 5x

We need to find the length of BD.

BD = BE + ED ...(1)

We know that the diagonals of a parallelogram bisects each other. It means,

BE = ED

x+8 = 5x

8 = 5x - x

8 = 4x

x = 2

BE = (x+8)

= (2+8)

= 10

ED = 5x

= 5(2)

= 10

Put the values in equation (1).

BD = 10 + 10

= 20 units

Hence, the length of BD is 20 units.

Umm what? i have been stuck on this question for 30 minutes. help please​
Alex

Answer:

A

Step-by-step explanation:

a hyperbola is used in the form

(x-h)^2/a^2 - (y-k)^2/b^2

in this case h=1 k=2 a=6 b=8

since the x part comes first, use y = +-(b/a)(x-h) + k to find the asymptotes

we get y = +-(4/3)(x-1) + 2

multiply out the 4/3 to get

for +: (4x-4)/3 + 2

for -: (-4x+4)/3 + 2

change 2 to 6/3 and combine:

for +: 4x+2/3

for -: (-4x+10)/3
