Write an equation in slope-intercept form for the line that passes through (1,9) and (3,5).
kozerog [31]

Answer:

The answer to your question is    y = -2x + 11

Step-by-step explanation:

A (1, 9)

B (3, 5)

- Find the slope

 m = \frac{y2 - y1}{x2 - x1}

 m = \frac{5 - 9}{3 - 1}

 m = \frac{-4}{2}

        m = - 2

- Find the line equation

        y - y1 = m (x - x1)

        y - 5 = -2(x - 3)

        y - 5 = -2x + 6

        y = -2x + 6 + 5

        y = -2x + 11

The functions f(x) = x2 – 3 and g(x) = –x2 + 2 are shown on the graph.
docker41 [41]

The set of inequalities y ≤ x² - 3 and y > -x² + 2 do not have a solution

<h3>How to modify the graphs</h3>

The attached figure 1 represents the missing piece in the question

From the graph, we have:

f(x) = x² - 3

g(x) = -x² + 2

Next, we change the equations to inequalities as follows:

y ≤ x² - 3

y > -x² + 2

To modify the graph, we then perform the following transformations:

  • Shift the function g(x) down by 2 units
  • Reflect across the x-axis
  • Shift the function g(x) down by 3 units

<h3>How to identify the solution set</h3>

After the modifications in (a), we have:

y ≤ x² - 3 and y > -x² + 2

Next, we plot the graph of the inequalities

From the graph of the inequalities, the curves of the inequalities have no point of intersection

Hence, the set of inequalities do not have a solution

The vertex angle of an isosceles triangle measures 40°. What is the measure of a base angle?
Katena32 [7]
A triangle has three angles, and their measures add up to 180 degrees.
An isosceles triangle has at least 2 congruent sides, and the angles opposite the congruent sides are congruent.

This triangle has one angle of 40 deg, and two angles that measure the same; call the measure of each base angle x.

x + x + 40 = 180

2x + 40 = 180

2x = 140

x = 70

The base angles measure 70 deg.
