2 is less than 5 so rounds down to 88
Answer:
k = 3.
Step-by-step explanation:
k + 4 = 7 Add -4 to both sides:
k + 4 - 4 = 7 - 4
k = 3.
Step-by-step explanation:
first we need to find the slope of the line.
the slope is the ratio of "y coordinate change / x coordinate change" when going from one point to the other.
we see here
x changes by -4 (from -4 to -8).
y changes by +3 (from -5 to -2).
so, the slope is +3/-4 = -3/4
there are two main forms for the equation of a line :
the slope-intercept form
y = ax + b
and the point-slope form
y - y1 = a(x - x1)
where "a" is the slope, and (x1, y1) is a point on the line.
we can pick any point, and I would pick (-4, -5).
so we get as point-slope form
y + 5 = -3/4 × (x + 4)
or for the slope intercept form we simplify the point-slope form
y + 5 = -3/4 x + -3/4 × 4 = -3/4 x - 3
y = -3/4 x - 8
Answer:
so he has 100$ left
Step-by-step explanation:
He spends 1/5 of his salary on two chairs that is 100$
then He spends 3/5 of his salary on an air conditioner for his new apartment that is 300$
so he has 100$ left
