Y=2x-8 would be your answer

Andrei [34K]1 year ago

Answer:

y=2x-8

f(x)=2x-8

Step-by-step explanation:

To write in slope-intercept form using this information, first use the point slope formula.

y-y1=m(x-x1)

m is slope.

y+4=2(x-2)

Use distributive property on the right side.

y+4=2x-4

Now, subtract 4 from both sides.

y+4-4=2x-4-4

y=2x-8

Written using function notation:

f(x)=2x-8

Hope this helps!

If not, I am sorry.

What is 3/8 as an equivalent fraction with the LCM as the denominator?

tino4ka555 [31]

Answer:

3/8 = 9/24

Step-by-step explanation:

So here we have a basic multiplication problem and finding the LCM of 8 and 3. The first step in this problem is finding the LCM of 3/8. The LCM of 3 and 8 is 24. So yay! we have the bottom half of our answer!

Ex.-

The LCM of 8 and 3 is 24.

So now we have to find an equivalent fraction. Since we already know that 8 (the denominator in the original equation) can be multiplied by 3 to equal 24, we use 3 (the numerator in the original equation) and multiply it by itself to get an equivalent fraction.

Ex.-

8 x 3 = 24

3 x 3 = 9

Now that we have our numerator and denominator, all we have to do now is put them together to get our answer.

Ex.-

9/24 (answer) = 3/8 (original equation)

Hopefully I could help! :)

Simplify the expression 9−8b+6b 9−8b+6b . 9−8b+6b=?? haha last one XD

Vladimir79 [104]

You should get it now from my previous answer.

But to apply it.

9 - 8b + 6b
9 + (-8b + 6b) <- Collect like bases (b)
9 + (-2b)
9 - 2b

Therefore it simplified is 9 - 2b

At 12pm, the temperature was 57o F. By 5pm, the thermometer read 36o F. Assuming a constant change in temperature, calculate and

BaLLatris [955]

Answer:

Unit rate of change = -4.2°F/hour

Step-by-step explanation:

Assuming a constant rate of change, a relationship between the change of temperature as a function of time (in hours) can be described as follows:

$r= \frac{(36^oF - 57^o F)}{17 - 12}\\r= \frac{-4.2^o F}{hour}$

There is a temperature drop from 12pm to 5pm, which explains the rate of change being negative. This rate means that at every hour that goes by, the temperature drops by 4.2 degrees.
