Given:
The equation of a line is
To find:
The slope and y-intercept of the line.
Solution:
We have,
...(i)
The slope intercept form of a line is
...(ii)
Where, m is the slope and b is the y-intercept.
On comparing (i) and (ii), we get
Slope of the line = 1
y-intercept of the line = -4
The coordinate form of y-intercept is (0,b). So, the y-intercept of the given line is (0,-4).
Therefore, the slope of the line is 1 and the y-intercept is (0,-4).
Answer:
x=150
y=240
Step-by-step explanation:
*Use simultaneous equation solving
1.Label your equations
x+y=390......1
2x+4y=1260......2
*make one of the unknowns subject of formula, to form equation 2
x=390-y.....3
*sub.3 into 2
2(390-y)+4y=1260
780-2y+4y=1260
2y+780=1260
y=240
sub. y into 3
x=390-y
x=390-240
x=150
Answer:38
Step-by-step explanation:if you take 24 and subtract the five she added, it gives you 19 and since she divided it by two you would multiply it by two to get the original number she was thinking of
Hope this helps :)
Step-by-step explanation:
let an amount be a
increase an amount by 10% and then by 30%
= a*1.1 *1.3 = a*1.43
