If (-3, y) lies on the graph of y = 3x, then y =

Answers

y = 3 x
(-3, y ) , x = -3
y = 3 · ( -3 )
y = - 9
Thank you.

Answer:

The value of y=-9

Step-by-step explanation:

If (-3, y) lies on the graph of y = 3x

If any point satisfy the equation or graph. We get true for that point.

Now, we substitute the point into equation and left side is equivalent to right side.

Put x=-3 and to solve for y

y=3(-3)

y=-9

If x=-3 then y=-9

Hence, The value of y=-9

The scenarios that best represent the relationship between the variables would be B. It not only properly defines the variables but also, uses the correct pairs of numbers to go along with the variables of x and y.

A cereal company used to fill the boxes with 16 ounces of cereal. They have reduced that amount to 14 ounces. The percent decrease is 87.5%. True or false

Answers

Answer:

False

Step-by-step explanation:

Given: A cereal company used to fill the boxes with 16 ounces of cereal. They have reduced that amount to 14 ounces.

Decreased amount = 16 -14 = 2 ounces.

Now let's find the decreased percentage using the following formula.

Decrease percent = $(decreased amount)/(original amount) *100$

= $(2)/(16) *100$

= $(200)/(16)$

= 12.5%

The percentage of decrease is 12.5%.

Therefore, the answer is false

This is a true statement

%87.5 = .875 in decimal form
multiply 16 by 8.75 and it will give you 14

hope this helped

What are the three steps involved in subtracting radicals? A) Adding, simplifying, and reducing. B) Finding common denominators, multiplying, and factoring. C) Simplifying, combining like terms, and subtracting. D) Expanding, reducing exponents, and using the distributive property.

Answers

Answer:

C) Simplifying, combining like terms, and subtracting.

Step-by-step explanation:

1. Simplifying: Simplify each radical separately by finding perfect square factors and simplifying any radicals if possible.

2. Combining like terms: Combine the simplified radicals with the same radical part. Add or subtract the coefficients.

3. Subtracting: Subtract the combined radical expressions obtained in the previous step.
