M = - 1/5
y = m x + b
7 = - 1/5 · ( - 3 ) + b
7 = 3/5 + b
b = 7 - 3/5
b = 35/5 - 3/5
b = 32/5
The equation is:
y = - 1/5 x + 32/5 or : y = - 0.2x + 6.4
Answer:
3/7 x +5=8
move 5 to the other side
3/7 x= 8-5
3/7 x= 3
then move 7 to the other side it's sign is ÷ it will be ×
then 3x=3×7
3x=21
then move 3to the other side it's sign is × it will become ÷
x= 21/3
x= 7
Answer:
D.
Step-by-step explanation:
If you look at the pattern, the first shape (square) has four sides. Then, you have 5 sides, and finally, 6 sides.
Thus, a pattern of 4, 5, 6. So, the next shape must have 7 sides, leaving the only possible answer as D.
Answer:
Distance between line and point =
4√5 -3/2√10
Step-by-step explanation:
Distance between the line is
= √ ((9-0)²+(0+1)²)
= √ (89+1)
= √90
= 3√10
Half of the line = 3/2√10
Distance of one side of the line and the point.
= √((9-1)²+(0-4)²)
= √((8)²+(-4)²)
=√64+16
= √80
= 4√5
Distance between line and point =
4√5 -3/2√10
