Answer:

Step-by-step explanation:

Slope of line passing through (x_1,y_1) and (x_2,y_2) is given by,

m = \frac{y_2-y_1}{x_2-x_1}

From the graph attached,

Slope of the line passing through (-3, 0) and (0, 5) = \frac{5-0}{-3-0}

                                                                                    = -\frac{5}{3}

Line passing through a point (h, k) and slope 'm' will be,

y - h = m(x - k)

Since, line passing through (11, 0) is parallel to the line given in the graph,

Slope of the parallel line will be same as -\frac{5}{3}

Equation of a line passing through (11, 0) and slope = -\frac{5}{3}

y - 0 = -\frac{5}{3}(x-11)

y = -\frac{5}{3}(x-11)

Now satisfy this equation with the points given in the options,

Option (1)

For (1.67, -15.59),

-15.59 = -\frac{5}{3}(1.67-11)

-15.59 = -15.55

False.

Therefore, given point doesn't lie on the line.

Option (2)

For (-0.33, -13.59)

-13.59 = -\frac{5}{3}(-0.33-11)

-13.59 = -18.88

False

Option (3)

For (0.67, -18.59),

-18.59 = -\frac{5}{3}(0.67-11)

-18.59 = 17.22

False

Option (4)

For (1.67, -15.59)

-15.59 = -\frac{5}{3}(1.67-11)

-15.59 = -15.55

False.

Therefore, none of the points given in the options are lying on the line.

• The outside temperature changes -4.8°F in 4 hours. What is the average change in temperature each hour?
Whitepunk [10]

Answer:

-1.2°F

Step-by-step explanation:

-4.8F = 4 hours

Divide both sides by 4 to get one side to 1 hour

-4.8F/4 = 4 hours / 4

-1.2F = 1 hour

Mr. Adams will be serving 20 people at a barbecue. He plans to make two hamburgers for each person. Mr. Adams spent $27.00 at th
Crank
That is 0,3 pounds per hamburger for all 40 hamburgers he will make.at $2.25/ per pound you buy 12 pounds for $27.
12 pounds divided by 40 is 0.3 pounds. That's the weight in pounds of each meat in each hamburger.

Determine the x intercepts of the piecewise function in the image that I sent.
Amanda [17]

To find the x intercept of the function, we would find g(x) = 0

To do this, we would set each expression in the piecewise function to zero and solve for x. We have

For

x/3 + 2 = 0

let us multiply both sides of the equation by 3. We have

x/3 * 3 + 2 * 3 = 0 * 3

x + 6 = 0

x = - 6

- 6 is less than - 1

- 6 < - 1

It satisfies the inequality. Thus, x = - 6 is in the domain

For

4x - 2 = 0

adding 2 to both sides of the equation, we have

4x - 2 + 2 = 0 + 2

4x = 2

Dividing both sides of the equation by 4, we have

4x/4 = 2/4

x = 1/2

x = 1/2 is less than 1. It is not in the domain of this equation. Thus, there is no x interscept at x = 1/2

Therefore, the x intercept of the piecewise function is (- 6, 0)
