Inequality: 21d+25≤115

Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.

Step-by-step explanation:

Given,

Per day rent = $21.00

Per mile rent = $0.10

Miles to be driven by Jim = 250

Cost of 250 miles = 250*0.10 = $25

Amount Jim can spend = $115.00

Let,

d represent the number of days.

Per day rent*number of days + cost of 250 miles ≤ Total amount to spend

21d+25≤115

Subtracting 25 from both sides

$21d+25-25\leq 115-25\\21d\leq 90$

Dividing both sides by 21

$\frac{21d}{21}\leq \frac{90}{21}\\d\leq 4.28$

Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.

HELP!! What is the equation of the graphed line?<br> (y=mx+b)

Anettt [7]

So to fine slope you would use the formula down below:

rise/run

So use a graphed point, 0, -5 and you rise or count up quadrants up to a point and then horizontally move to when you find that point.

So from 0,-5 go up 9 vertically, and you would be on the 4

Go horizontal 3 spots and your on a designated point.

So the rise is four and the run is 3

So 4/3 is the slope

In the y= Mx + b equation you would set the equation like this:

y= 4/3 + -5

The m in this formula stands for the slop and the b stands for the y-intercept

The y-intercept is the point that is on the y-axis and where it starts.

What are the zeros of the function g(x) = (x + 6) (x – 4)(x + 2) ?

vitfil [10]

Answer:

x in {-6, -2, 4}

Step-by-step explanation:

The zero product rule tells you that a product will be zero if and only if one of the factors is zero. These binomial factors are zero when x has a value that is opposite the constant of the binomial.

x +6 = 0 ⇒ x = -6

x -4 = 0 ⇒ x = 4

x +2 = 0 ⇒ x = -2

The zeros of the function are the x-values -6, -2, and 4.
