I may be wrong, but im pretty sure its C
Answer:
Step-by-step explanation:
<h3>Given </h3>
- Point (5, -7) and midpoint (15, 1)
<h3>To find</h3>
<h3>Solution</h3>
<u>Midpoint formula:</u>
- x = (x1 + x2)/2,
- y = (y1 + y2)/2
<u>Substituting values:</u>
- 15 = (5 + x2)/2 ⇒ 5 + x2 = 30 ⇒ x2 = 30 -5 ⇒ x2 = 25
- 1 = (-7 + y2)/2 ⇒ -7 + y2 = 2 ⇒ y2 = 2 - (-7) ⇒ y2 = 9
<u>Missing endpoint is:</u>
The slope formula:
m - a slopeb - y-intercept
We have:
and point
Substitute:
Answer: A.
Answer: 15 students
Step-by-step explanation:
From the question, we are informed that there are 150 students in 6th grade, and that 10% earned straight As last quarter.
The number of students that earned straight As will be:
= 10% × 150
= 10/100 × 150
= 0.1 × 150
= 15 students
