Move 3x to the other side of the equal sign. You are then left with y=-3x+10.

Just make the equation look like this y = mx + b
So 3x + y =10 would equal y = -3x + 10

∫(x+1)/(x2+2)2x−3dx need help with this question. can you show the process

kenny6666 [7]

do you need to include the wiggle infront of the first bracket? if not;

(x+1) ÷ [(x^2+2) x (2x-3dx)]

x^2 x 2x = 2x^3

x^2 x -3dx = -3dx^3

2 x 2x = 4x

2 x -3dx = - 6dx

i cant find a way to make it equal 0 so i think the answer is just

x+1 over 2x^3 - 3dx^3 + 4x - 6dx as a fraction

Tickets for a concert are $40 for main-floor seats and $25 for upper level seats. A total of 2000 concert tickets were sold. The

Tems11 [23]

Step-by-step explanation:

to show how many tickets were sold:

x = upper floor tickets

y = main floor tickets

x + y = 2000

to show total amount of revenue:

25x + 40y = 62,000

Finding answer using both equations:

x + y = 2000

multiply each side by 25

25x + 25y = 2000 × 25

25x + 25y = 50,000

25x + 40y = 62,000

25x + 25y = 50,000

-----------------------------------

15y = 12,000

^ this is column subtraction

^ this column subtraction is done to isolate y so we can work with one value rather than 2

15y = 12,000

divide each side by 15

12,000 ÷ 15 = 800

y = 800

x + y = 2000

x + 800 = 2000

x = 1200

Therefore 1200 upper-level tickets were sold

800 main floor tickets were sold

Tania has 6 tiles with pictures of plants and 3 tiles with pictures of animals. Tania keeps all the tiles on a mat with the pict

Natalka [10]

Initially there were 6 tiles with pictures of plants and 3 tiles with pictures of animals.
She removes one tile with the picture of a plant, so now there are 5 tiles with pictures of plants and 3 tiles with pictures of animals. There are 5+3=8 tiles in total.

The probability that the second tile has a plant on it is the number of tiles with pictures of plants (5) divided by the total number of tiles (8).

The probability is $\frac{5}{8}$ .
