Answer:

1:50 PM

Step-by-step explanation:

Left school at 10:38 AM,

took them 51 minutes,

38+51=89,

89-60=29,

so when they drove to the museum, it was 11:29 AM.

From here, they stayed at the museum for 1 hour and 26 minutes,

so they stayed at the museum until 12:55 AM since 29+26=55.

Now, it took them 55 minutes to drive back to the school,

so 12:55 plus another 55 minutes,

it's going to be 1:50 PM when Dale's class got back to school.

What is the slope intercept from of the equation of the line that passes through (7, -5) and (3, -9)

never [62]

Answer:

B. $y = x - 12$

Step-by-step explanation:

First, find the rate of change [slope]:

$\frac{-y_1 + y_2}{-x_1 + x_2} = m$

$\frac{5 - 9}{-7 + 3} = \frac{-4}{-4} = 1$

Then use the Slope-Intercept Formula instead of the Point-Slope Formula because you get it done faster that way. It does not matter which ordered pair you choose:

−9 = 3 + b

−12 = b

$y = x - 12$

________________________________________________________________________________________________

−5 = 7 + b

−12 = b

$y = x - 12$

** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

I am joyous to assist you anytime.

What is x divided by x-1 - 1 divided by 2-2x expessed as a single fraction ?

Kay [80]

To simplify into 1 fraction, remember, we must make the denominator the same
x/ (x-1 ) - 1/ (2-2x)
= -x/ -(1-x) - 1/(2-2x) [see the similarity now? ] [whatever we multiply for the denominator, as long as we multiply to the numerator, it will be ok]
= -2x / -(2-2x) + 1/-(2-2x)
= (-2x+1 )/ -(2-2x)
=(2x-1)/(2-2x)
