Answer:
I think it is -3 + -3 = -6 (as blue vectors suggested)
Well if it was 8 hours in the morning and 7 in the evening per day of the week it would be 105 divided by 2 for the number of sessions would equal to 52.5 sessions. if it was just that amount of time from that whole week, it would be 15 hours divided by 2 which would give you 7.5... Did that help?
Answer:
D. m = 20 , n = 10.
Step-by-step explanation:
The sine of 60 is √3/2, so
sin 60 = 10√3 / m = √3/2
√3 m = 20 √3
Divide both sides by √3:
m = 20.
cos 60 = 1/2 = n / 20
2n = 20
so n = 10.
Answer:
x= -9
Step-by-step explanation:
2(x - 3) + 1 = 3x + 4
2x-6+1=3x+4
2x-5=3x+4
-2x -2x
-5=x+4
-4 -4
-9=x
Hope this helps! ;)
Answer:
so looks like they want you to solve each of them first, then plot them on the number lines.
1) x+8 >= 18
subtract 8 from each side
x >= 10
so for this one you would plot the point (a closed circle, since it's greater than or equal to) on the ten, and draw an arrow pointing to the right
2) x-1 > 6
add 1 to each side
x > 7
for this one you would plot an open circle on the 7 and draw an arrow to the right
3) -7+x >= -8
add 7 to each side
x >= -1
for this one you would plot a closed circle on the -1 and draw an arrow to the right
4) x-1 <= 3
add 1 to each side
x <= 4
for this one you would plot a closed circle on the 4 and draw an arrow to the left
