Answer:

Step-by-step explanation:

<u>Linear Function</u>

The linear function is widely used to model real situations in life where the dependancy of one variable are linear by nature.

The problem gives us three conditions, more than enough to find a linear model for the earnings for running errands. Let's make x the number of hours it takes to run the errands, and y the earnings. The linear model has the general equation

$y=mx+b$

We have these points (1,20) (2,35) (3,50) and need to find the base fee, which is the value of b or the independant term of the equation.

We'll use the first two points to find the equation and the third point to verify it. Using (1,20)

$20=1\cdot m+b$

$m+b=20$

Now we use (2,35)

$35=m\cdot 2+b$

$2m+b=35$

Subtracting both equations

$m=15$

Replacing into the first equation

$b=5$

The equation is

$y=15x+5$

Let's test the formula by replacing the point x=3

$y=15\cdot 3+5=50$

The model is accurate and the base fee is 5

Answer:

-4

Step-by-step explanation:

To find the slope, you can use the formula y2-y1/x2-x1. Plugin any set of values. Say 13 is y2, and 5 is y1. 13-5=8. We now have 8/x2-x1. You have to use the x-values of the y-values that you already used. -2 is x2 and 0 is x1. -2-0=-2. 8/-2 = -4.

Which shows the correct substitution of the values a, b, and c from the equation 0 = – 3x2 – 2x + 6 into the quadratic formula?

ZanzabumX [31]

Answer:

shows correct substitution of the values a, b, and c from the given quadratic equation into quadratic formula.

Step-by-step explanation:

Given: The quadratic equation

We have to show the correct substitution of the values a, b, and c from the given quadratic equation into quadratic formula.

The standard form of quadratic equation is then the solution of quadratic equation using quadratic formula is given as

Consider the given quadratic equation

Comparing with general quadratic equation, we have

a = -3 , b = -2 , c = 6

Substitute in quadratic formula, we get,

Simplify, we have,

Thus, and x_{2}=\frac{2-\sqrt{76} }{-6}

Simplify, we get,

Thus, shows correct substitution of the values a, b, and c from the given quadratic equation into quadratic formula.
