Is (1,-4) a solution to the equation y=-2/?
A yes
В. no

Answers

Answer: B.no

Step-by-step explanation:

To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer

HI PLEASE ANSWER BEFORE 12:00a.m. EST

Answers

Answer:

Step-by-step explanation:

Amanda's unit rate would be

s=50m

while Mary's is

s=60m

60-50 is 10, meaning the answer would be D.

Mary saves $10 more than Amanda every month.

Hope this helps! :)

Hi there!

We can find an equation that models Amanda's savings using the equation:

y = km, where:

k = rise / run (Amount/months)

Plug in a set of values from the table:

k = 100/2 = 50

y = 50m

We know that Mary saves y = 60m dollars a month, so we can determine the correct comparison by plugging in a value of 1 month into both equations:

Amanda:

y = 50(1) = $50

Mary:

y = 60(1) = $60

The difference between Mary's and Amanda's savings is $60 - $50 = $10, so each month, Mary saves $10 more than Amanda.

The correct answer is D.

At 12 noon if the temperature is 38°C and if it decreases at the rate of 2°C per hour, then what would be the temperature at 5pm?

Answers

Answer:

38-2(5) = 28

So the temperature would be 28 degrees celsius

Answer: Teperature at 5PM will be 28°C

Ok so at 12 its 38°C

And it dcreases at 2°C an hour, we need to find the teperature at 5 o clock.

The number of hours between 12 and 5 mutiplied by 2 will give us the trail in temperature and then subtracting the trail i temperature witht the temperature a 12 will give us the teperature at 5 o clock.

SO,

hours between 12 PM and 5 PM is 5 hours

As, the temperature decreases at a uniform rate of 2°c per hour

⇒5×2°C

⇒10°C

Now the temperature at 5 PM will be 38°C-10°C=28°C
