Answer: y=-2x+6
Step-by-step explanation:
To write the equation in slope-intercept form, you want to solve for y.
y-6=-2x [add both sides by 6]
y=-2x+6
Now, we have the equation in slope-intercept form.
X - y = -3
y = x + 3.......slope = 1, y intercept = (0,3)
to find x int, sub in 0 for y and solve for x
x - y = -3
x - 0 = -3
x = -3....so the x intercept = (-3,0)
plot ur points (0,3) and (-3,0)......now start at (-3,0)....and since ur slope is 1, go up one, and to the right 1, and up 1, and to the right 1.....do this over as many times as needed and u should cross the y axis at (0,3)
Answer:
18.2
Step-by-step explanation:
tan 70 = 50/x
x = 50/ tan 70
A(x1, y1), B (x2,y2)
d=V(y2-y1)^2+(x2-x1)^2
d^2= (1-4)^2+[5-(-2)]^2=(-3)^2+ (5+2)^2=9+49=58
d=V58
Answer:
The speed of the bus is 40mph.
Step-by-step explanation:
Given that increase in 20% causes the bus to drive at 48mph. In order to find the original speed, we can assume that the original speed is 100% :
100% + 20% = 48mph
120 % = 48mph
1% = 0.4mph
100% = 40mph
