How do i graph 2x + 3y = 9

Answers

Answer 1

1) Find the y - intercept
you can do this by finding the value for y:

2x+3y=9 —-> move 2x to the other side

3y = -2x + 9 —> then divide both sides by 3

y = -⅔x + 3 <— this is your y-intercept

to graph this, start from the point (0,0)
your first point will be the constant which in this case is number 3

so plot this 3 on your y- axis on your grid

from there, your term in the equation which in this case is -⅔x

from your first point which is (0,3) you either:

go up two times, go left three times

or

go down two times, go right three times

3(x+1)+11<-2(x+13)

show steps please
thanks!

Answers

Answer:

x < - 8

Step-by-step explanation:

Given

3(x + 1) + 11 < - 2(x + 13) ← distribute parenthesis on both sides

3x + 3 + 11 < - 2x - 26

3x + 14 < - 2x - 26 ( add 2x to both sides )

5x + 14 < - 26 ( subtract 14 from both sides )

5x < - 40 ( divide both sides by 5 )

x < - 8

Answer:

x<-8

Step-by-step explanation:

3x+14<-2x-26(combine and distribute)

3x+14-14<-2x-26-14(subtract 14 from both sides)

3x<-2x-40(add 2x to both sides)

5x<-40(divide both sides by 5

x<-8(this is your final answer)

Lata has collected 75 pennies, Lata's father says that if she arranges the pennies in 15 rows, Lata will be able to make a rectangle using all of her pennies. Is her father correct?

Answers

Answer:

Yes, Her father is correct.

Step-by-step explanation:

75/15=5 which means that there will be fifteen rows, with five pennies in each row. Since one side has 5 pennies and the other has fifteen, the sides are different and form a rectangle. To check your work, you can do 15*5 which equals 75 the rectangle of pennies should look like this:

A bag contains only red, green, brown and yellow marbles. The probabilities of selecting each colour are shown below. red=5x green=2x brown=3x yellow=4x Find the probability of selecting a yellow marble. P(Yellow)=?

Answers

Answer:

28.57%

Step-by-step explanation:

In order to find the probability of selecting a yellow marble we first need to calculate the total number of marbles in the bag. We do this by adding the number of individual colored marbles together.

5 + 2 + 3 + 4 = 14 total marbles

Now that we have the total number of marbles in the bag we need to divide the number of yellow marbles by this total to get the probability in decimal form.

4 (yellow) / 14 (total) = 0.2857

Now we need to multiply this decimal by 100 to get the percentage probability.

0.2857 * 100 = 28.57%

Finally, we can see that the probability of selecting a yellow marble is 28.57%

2.5 counters

Step-by-step explanation:

On the right, there are 8 spheres. Since the scale is balanced, we can assume there is an equivalent of 8 spheres on the left side. We can clearly see three spheres (in red), so we'll subtract that from the 8. The canisters (blue) are the same weight, and make up 5 spheres togther. So, divide by 2, and your answer is the blue canister is equal to 2.5 spheres/counters.
