Answer:

Step-by-step explanation:

"y = 1 5 x" is ambiguous; please do not leave spaces.  I'm assuming you meant y = 15x.

If you graph this, you'll see a line with slope 15 that goes through the origin.  If there were a y-intercept other than zero, such as in y = 15x + 5, this equation would not represent a proportional relationship.

In summary:

There's a constant ("constant of proportionality") slope, which here is 15.

The line MUST go through the origin.

<h2>Answer:</h2>

When you graph the equation, you get a straight line that passes through the origin, which means the relationship is proportional. The constant of proportionality is the y-value when x = 1, which is 1/5.

If m equals 3, and we have a y and x value of 8 and -8, all we have to do is solve for b.

-8 = 3(8) + b
Multiply 8 and 3.
-8 = 24 + b
Subtract 24 from both sides to isolate b.
-32 = b

Your equation would look like this:

y = 3x - 32

A pound is a(lager, smaller) unit than an ounce, so (divide, multiply) the number of pounds by 16 to find the number of ounces.
worty [1.4K]

Part A:

(larger)

(multiply)

(32)

Part B:

you didnt give any context. But to turn pounds into ounces multiply it the pounds by 16 (2lbs. × 16 = 32oz.)

and once you have the total number of ounces divide it by how many ounces her mom drinks in a day (ex. 32÷4= 9) and if that number is larger than 7 then yes, theres enough coffee

Can someone tell me the answer to both of these
omeli [17]

Answer:

First question --> C) 8.5h

Second question --> D) 2

Step-by-step explanation:

First question

Terry earns $10 per hour

Jill earns 20% less which is $2 less

Jill earns $8 per hour

Jerry earns $0.50 more per hour than Jill

Jerry earns $8.50 per hour

Second question

x = 2

y = 4

(2x + 3y) / 4 - 2 = ?

Use PEMDAS

so Parentheses first, then divide, then subtract

So.... (2x + 3y) = (2*2 + 3*4) = (4 + 12) = 16

Then divide

16/4 = 4

Then subtract

4 - 2 = 2
