Rewrite each equation in slope-intercept form, if necessary. Then determine whether the lines are parallel. Explain,

1 answer:

8 0

Answer:
d

Step-by-step explanation:

Slope intercept form: y = mx + b

y = -x + 7
x + y = 21

x + y = 21
-x -x
y = -x + 21

y = -x + 7
y = -x + 21

Parallel lines have the same slope. Here, our slope is -1

Therefore, our final answer is d.

Hope this helps!

A middle school held a Career Exploration Day where students could choose to hear an adult talk about his or her career. 15 stud

mash [69]

Answer:

5/12

Step-by-step explanation:

15 students went to hear the doctor speak and 21 students went to other sessions

How many students are there? 15 + 21 = 36 students

Therefore, the probability to randomly select a student that went to hear the doctor is $\frac{15}{36}$ , then simplifying it by 3 is $\frac{5}{12}$ .

If we want to express it in percentage it would be 41.6%
