Answer:
for y=-3x+9 it has 3 solutions
for 3y=-9x+9 it also has 3 solutions
Step-by-step explanation:
Put the numbers in order from smallest to largest:
15, 19, 20, 25, 25, 28, 29, 30, 35, 37, 38, 43
Part A:
minimum = 15
maximum = 43
Q1 = (25+20) /2 = 45/2 =22.5
Q2= (28+29) /2 = 57/2 = 28.5
Q3 = (35+37)/2 = 72/2 = 36
Part B: Range = Maximum - minimum = 43-15 = 28
C: IQR = Q3 - Q1 = 36 - 22.5 = 13.5
4,4 1/4,4 2/4, 4 3/4, 5, 5 1/4, 5 2/4, 5 3/4, 6
Answer:
These Lines will be parallel.
Step-by-step explanation:
You have to find the slope of each line. For (1,1) and (3,3) the slope is 1 and for Line 2 the slope is also 1. (let me know if you want me to show the work for slope). To have parallel lines the slopes have to be the same and y-ints have to be different. Here the slopes are the same and in Line 1 the yint is (0,0) which is different than Line 2. Therefor the Lines are parallel.
Sorry if im wrong!. Hope this helps
Answer:
(3.5 , 3.5)
Step-by-step explanation:
Midpoint formula is x1+x2/2 and y1+y2/2
7 + 0/2 and 9 + (-2)/2
7/2 simplifies to 3.5
7/2 again simplifies to 3.5
so the midpoint coordinate is
(3.5,3.5)
