Answer:
y = 3
Step-by-step explanation:
Use the slope formula:
y2 - y1
m = ------------- , which here becomes
x2 - x1
y - 5 -1
m = ------------- = -----
8 - (-2) 5
Solve this for x. Cross multiplication yields:
5y - 25 = -1(10) = -10
Then 5y = 15, and y = 3
The mean is the average. To find this, we add up all the numbers, then divide by the number of numbers there are.
12+23+17+20+14+14+18+16+17+18+18= 187
187/11=17
The mean is 17.
The median is the middle number. To find this, line up all the numbers, smallest to largest.
12, 14, 14, 16, 17, 17, 18, 18, 18, 20, 23
You then cross off numbers from both sides, until you have 1 number remaining.
Your median is 17.
The mode is the number that occurs most frequently.
Your mode is 18.
Answer:
C. an open circle with the arrow going to the right
Step-by-step explanation:
x > -19
Since there is no equals bar, there is an open circle at -19
X is greater so the line goes to the right
Ok so all you have to do is set SPR and QPR equal like this
4x+11=5x-4
and solve to get x=15
then substitute in 15 for x in both equations
4(15)+11 and 5(15)-4
both =71 and add them up to get SPQ=142.
Answer:-11/32
Step-by-step explanation:
-7/8 - (-17/32)
= -7/8 + 17/32
The highest common factor is 32
= (-7*4+17)/32
= (-28+17)/32
= -11/32
