Y = 1/4 x - 2
=> a linear function => a straigh line
=> slope = the coefficient of x => slope = 1/4
=> x = 0 => the y-intercept = -2
=> y = 0 => 0 = 1/4 x - 2 =>x = 8 => point (8,0)
With all that information you can identify the graph because it is a straight line that passes through (0,-2) and (8,0), its inclination (slope) is 1/4, and the graph goes through the quadrants I, III and IV (there are no points in the quadrant II)..
Answer:
Step-by-step explanation:
Let number be x and y
x+y=56.........eqn(I)
x-y=4..............eqn(ii)
x=4+y.........eqn(iii)
Substitute eqn (iii)&(I)
You get y=26
From eqn(iii)
You get x=30
Answer:
A, B and E
Step-by-step explanation:
y = (1/2)x has the form y = kx, with k = 1/2, its constant of proportionality.
A) 6y = 3x
y = (3/6)x
y = (1/2)x
B) We have to find the slope of the line. Using points (0,0) and (4, 2)
slope = (2 - 0)/(4 - 0) = 1/2
C) We have to find the slope of the line. Using points (0,0) and (2, 4)
slope = (4 - 0)/(2 - 0) = 2
D) We have to find the slope of the line. Using points (2,1) and (4, 3)
slope = (3 - 1)/(4 - 2) = 1
E) We have to find the slope of the line. Using points (4,2) and (10, 5)
slope = (5 - 2)/(10 - 4) = 1/2
Answer:
3,925
Step-by-step explanation:
I think you have to divide 7,850 by 2 and you get 3,925
I hope this helps out!
