The Pool Fun Company has learned​ that, by pricing a newly released Fun Noodle at $4, sales will reach 8000 Fun Noodles per day during the summer. Raising the price to $5 will cause the sales to fall to 6000 Fun Noodles per day. Assume that the relationship between sales​ price, x, and number of Fun Noodles​ sold, ​ y, is linear. Write an equation in​ slope-intercept form describing this relationship. Use ordered pairs of the form​ (sales price, number​ sold).type your answer in slope intercept b. predict the daily sales of Fun Noodles if the price is $4.50​

How many points of intersection will the following system of linear equations have? y = 9x, 3y = -3x - 5 a) 0 b) 1 c) 2 d) Infinite

Answers

Answer:

b

Step-by-step explanation:

given the system of equations

y = 9x → (1)

3y = - 3x - 5 → (2)

substitute y = 9x into (2)

3(9x) = - 3x - 5

27x = - 3x - 5 ( add 3x to both sides )

30x = - 5 (divide both sides by 30 )

x = - (5)/(30) = - (1)/(6)

substitute x = - (1)/(6) into (1) and solve for y

y = 9x = 9 × - (1)/(6) = - (9)/(6) = - (3)/(2)

point of intersection = ( - (1)/(6), - (3)/(2) )

I bet no one can solve this

Which property is illustrated by the equation (a+b)+c=c+(a+b)

Answers

Associative property of addition Which property is illustrated by the equation (a+b)+c=c+(a+b) is the associative property of addition. The associative property of addition groups addends together which still yields the same sum regardless of the clustering or grouping set.
For example:
1.           1 + (2 + 3) = 6 = (1 + 2) + 3
2.           1 + (2 + 7) = 10 = (1 + 2) + 7
3.           550 + (20 + 5) = 575 = (550 + 5) + 20

Find the number that makes the ratio equivalent to 4:9. 32:

Answers

Answer:

72

Step-by-step explanation:

First, divide 32 by 4 to see how many times larger the numbers in the second ratio are than in the first ratio. 32/4=8 This means that the numbers in the second ratio are 8 times larger than in the first

Then, since the second ratio’s numbers are 8 times bigger than those of the first ratio, you can multiply both numbers in the first ratio by 8. The problem already multiplied 4 by 8 for us, which is 32, so all we have to do now is multiply 9 by 8. 9*8=72, which means that 4:9 is equivalent to 32:72
