Answer:
5 units
Step-by-step explanation:
Find the distance between the point - 3, 2 and 1 - 1
Given data
x1= -3
y1= 2
x2= 1
y2= -1
The expression for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
subtitute
d=√((1-(-3))²+(-1-(2))²)
d=√((1+3))²+(-1-2))²)
d=√((4)²+(-3))²)
d=√16+9
d=√25
d=5
Hence the distance between the points is 5 units
is that a math question? can you type out the full question please?
(-0.2,1.2)
substitute 3x+2 for y and set them equal to eachother then plug in x for y
Answer:
Kobby is 1 and Nana is 6
Step-by-step explanation:
lets mark Kobby's present age x, than Nana's present age would be x+5.
four years later Kobby's age would be x+4, and Nana's x+5+4, or 2(x+4).
so
x+5+4=2x+8
x-2x=8-5-4
-x=-1
x=1
