magnitude = sqrt(6^2+4^2)
= sqrt ( 36+16)
=sqrt (52) = 7.2
angle = tan^-1(6/4) = 56 degrees
X=small number
x+1= second
x+2= third
3x+3=72
3x=69
x=23 smallest number
9/4 = 2 1/4
1/4 = 0.25
2.25 is your answer
hope this helps
Answer:
c)y = 5x
Step-by-step explanation:
The intercept is where the lines crosses the y axis
It crosses at (0,0), so the y intercept is 0
(2,10) (4,20) are two points on the line
We can find the slope by using
m = (y2-y1)/(x2-x1)
(20-10)/(4-2)
10/2
The slope is 5
The slope intercept form of the equation is y = mx +b
y= 5x+0
y= 5x
it was one important turning point in ww2 because it stopped the german advance into the soviet union
