Answer:
2.5n is larger than or equal to (> with the line under) 5.25
Step-by-step explanation:
let's say the number is "n"
2 1/2 of n is at least 5 1/4
at least is a synonym to larger than or equal to, which is the fourth symbol, >_ with the line underneath.
Answer:
X=-5/2
Step-by-step explanation:
First for Y=2x+5 you change the y into 0
Then you replace the 0 with 2x but change the sign so it will be -2x so it will look like -2x=5
then you divide both sides by 2
Finally you get -5/2
Hopefully this helps
Answer:
B
Step-by-step explanation:
given the sequence 11, 25, 39, 53, 67, the common difference is
d = 67 - 53 = 53 - 39 = 39 - 25 = 25 - 11 = 14 → B
Answer:
y= -3x+24
Step-by-step explanation:
First find the slope of the line
-x + 3y = -6
Add x to each side
3y = x-6
Divide by 3
3y/3 = 1/3 x -6/3
y = 1/3x -2
The slope is 1/3 since it is in the form y = mx+b where m is the slope
Perpendicular lines have slopes that multiply to -1
1/3 * m = -1
m = -1 * 3/1
m = -3
The slope of the perpendicular line is -3
Slope intercept form is
y = mx+b where m is the slope and b is the y interceot
y = -3x+b
We have a point ( 6,6)
6 = -3(6) +b
6 = -18+b
Add 18 to each side
6+18 = -18+b+18
24 = b
y= -3x+24
