Answer:
y = 8x + 3
Step-by-step explanation:
The line we are describing here is line p;
slope of line p = 8
y- intercept = (0,3)
y-intercept of a line is the point where it crosses the y-axis. At this point, the x = 0
So;
Slope of the line = 8
y-intercept = 3
Equation of the line;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
y = 8x + 3
Answer:
8) a, d, e
9) yes, he will have $5.75 (or 5 /34)
Step-by-step explanation:
Step-by-step explanation:
6.5 / 0.5
= 6.5 / (1/2)
= 6.5 * (2/1)
= 13.
Since 13 is unequal to 3.25,
we conclude 6.5 / 0.5 = 3.25 is false.
Let the three numbers be x, y and z respectively, then
x + y + z = 62 . . . (1)
y = x - 4 . . . (2)
z = 4x . . . (3)
The above three expressions could be used to represent the numbers.
Solving the three equations, putting (2) and (3) into (1) gives
x + x - 4 + 4x = 62
6x - 4 = 62
6x = 62 + 4 = 66
x = 66/6 = 11
x = 11.
y = 11 - 4 = 7
z = 4(11) = 44
x = 11, y = 7, z = 44.
Percent increase = ((new number - original number) / (original number)) x 100.
percent increase = ((3000 - 2500) / 2500)) x 100 =
(500 / 2500)....x 100 =
0.2 x 100 =
20% increase <====
