What is the slope of<br> the line parallel to 3x +<br> y = 12?
Doss [256]

Answer:

slope = -3

Step-by-step explanation:

1) Rearrange eqn into slope intercept form

slope intercept form: y = mx + b

where...

m = the slope

b = the y-intercept (where the line crosses the y axis)

3x + y = 12

y = -3x+12

2) Know parallel rule. A line that runs parallel has the same slope but a different y-intercept

So the slope is: -3

Jack's last six scores are 75,78,83,80,79,84. If he scores a 90 on the next test, by how much will his mean test score increase?
kondaur [170]

Answer:

1.46

Step-by-step explanation:

First find the the mean score before he made a 90.

\frac{75+78+83+80+79+84}{6} = 79.83

Now add the score of 90 and calculate.

\frac{75+78+83+80+79+84+ 90}{7} = 81.29

Subtract the two scores.

81.29-79.83 = 1.46

His mean test score increased by 1.46.
