Write an equation of the line that passes through the point (4,5) and has a slope of -2.
Marina86 [1]

Answer:

y = - 2x + 13

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2 , then

y = - 2x + c ← is the partial equation

To find c substitute (4, 5) into the partial equation

5 = - 8 + c ⇒ c = 5 + 8 = 13

y = - 2x + 13 ← equation of line

Mike forgot to replace the cap on a bottle of room freshener. The room freshener began to evaporate at the rate of 15% per day.
riadik2000 [5.3K]
Percentages are out of 100. So we'll multiply by 0.85 to represent the 15%

To find the y points on the graph we can use f(x) = 0.85^x*40

We'll input 1-5 for x to find y:

1:  0.85^1=0.85*40=34
2: 0.85^2=0.7225*40=28.9
3: 0.85^3=0.614125*40=24.57
4: 0.85^4= 0.52200625*40=20.88
5: 0.85^5=0.443705312*40=17.75

Therefore the answer is a graph of exponential function going down from left to right in quadrant 1 through the point 0, 40 and approaching the x-axis.

rjkz [21]

Answer:

The agency fee is 35% of one months payment ($4,116.66) or ($1,440.83)

all you had to do is 49,400 divided by 12 months and you get $4,116.66 and then you times that by 35% and you get $1,440.83
