How do you convert y=-x-3 to standard form?

Answers

Answer 1

Answer:

x + y = - 3

Step-by-step explanation:

The equation for standard form is Ax + By = C. Since there is an invisible 1 in front of both x and y, you can easily solve the problem by subtracting -1x from both sides to get 1x + 1y = -3 or x + y = -3

At a local fitness center, members pay an $8 membership fee and $4 for each aerobic class. Nonmembers pay $6 for each aerobic class. For what number of aerobics classes will the cost for members and nonmember be the same?

Answers

In the aerobics classes of 4 will the cost for members and nonmember be the same.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

At a local fitness center, members pay an $8 membership fee and $4 for each aerobic class.

And, Nonmembers pay $6 for each aerobic class.

Now,

We can formulate;

For members, the cost = $8 + 4x

Where, x is the aerobic class.

For nonmembers;

The cost = 6x

We can equate both the equation, we get;

6x = 8 + 4x

Solve for x as;

6x - 4x = 8

2x = 8

x = 4

Thus, In the aerobics classes of 4 will the cost for members and nonmember be the same.

An aerobic lesson will be defined as 'a'
For every member lesson, they pay $4, so they will be represented as 4a
For every non member lesson, they pay $6, so they are 6a
Don't forget members have to pay $8 at the start, so they have to be 4a + 8
So
4a + 8 = 6a is our final equation
Move the 'a's to one side, by subtracting 4a from each side, giving you
8 = 2a
Divide by 2 to isolate a
4 = a
After 4 aerobics classes, the cost will be the same

-9 * (-15) = 135
it's positive 135 because when you have negative time a negative it's always positive.

Answer:

Please mark me brainliest and I hope this helped!

135

Step-by-step explanation:

The product of something is what the outcome is when you multiply the numbers together. Since 9 and 15 are both negatives, they cancel each other out and become positives. Then we just multiply 9 and 15. That gives us 135.

Can the sum of two mixed numbers be equal to 2 ? Explain why or why not.

Answers

Answer=No.

No. To be a mixed number, a number must contain both a whole number and a fraction. The lowest whole number is 1, and since 1+1=2 there is no way to add on a fraction to both 1's.

60% of what number is 150?

Answers

Answer:

Step-by-step explanation:

To solve this you must make a proportion of x/150 60/100. Then you need to find the relation between 100 and 150 which is x 1.5. Then apply the same thing to 60 which results in 90.

Answer: 250

You must set this up as a proportion

Remember the percent is always over 100

150/x=60/100

Then solve the proportion

60x=15000

Get the x by its self

15000/60 is 250

x=250

Any help is appreciated!
