1 answer:

8 0

3

1.5 and 4.5 all are divisible by 1.5. Then you just have to find another number that is as well. I chose 3. Theres also 6, 7.5,9,10.5,12

Write the equation in slope-intercept form: answers y=1/2x, y=3x+1/2, y=1/2x+3, y=2x+3

AleksandrR [38]

The equation in the slope-intercept form is:

y = (1/2)*x + 3

<h3>How to write the equation?</h3>

A general linear equation is:

y = a*x + b

Where a is the slope and b is the y-intercept.

To get the slope, we need two points on the line, by using the graph we can identify the points: (0, 3) and (2,4)

Then the slope is:

$a = \frac{4 - 3}{2 - 0} = 1/2$

And we also can see that the y-intercept is y = 3, because of the point (0,3)

Then the line is:

y = (1/2)*x + 3

The scatter plot below shows the profit earned each month by a new company over the first year of operation.

raketka [301]

Explanation:

To determine the slope and y-intercept of the equation, let us plot the coordinates in the slope-intercept form.

Analyzing the graph, some of the points that are on the straight line is (1,0),(3,5), (9,20)

Let us consider the points (1,0),(3,5) to determine the slope.

$\begin{aligned}m &=\frac{5-0}{3-1} \\&=\frac{5}{2} \\&=2.5\end{aligned}$

Since, the profit is earned in thousands of dollars, m = 2.5 or m = 2500

Thus, slope = 2500

To determine the y- intercept, let us substitute any one of the coordinate from the graph.

Thus, let us substitute (1,0) in the equation $y=mx+b$ to determine the y-intercept.

$0=2500(1)+b\\$

Simplifying, we have,

$b=-2500$

Hence, the line of best fit equation is $y=2500x-2500$

The angle measurements the carpenter needs to cut the carpet to make it fit in his room are 144°, 144°, 144°, 144°, 144°, 90°, and 90°

<h3>Angles in a polygon</h3>

From the question, we are to determine the angle measurements that the carpenter needs to cut the carpet to make it fit in his room

The diagram shows a heptagon with two of its angles, a right-angle each, and the remaining angles have equal values, x.

First, we will calculate the sum of angles in a heptagon

The sum of angles in a polygon is given by the formula

Sum of angles in a polygon = (n-2)180°

Where n is the number of sides

For a heptagon, n = 7

∴ Sum of angles in a heptagon = (7-2)180°

= 5×180°

= 900°

Now, considering the given diagram, we can write that

x + x + x + x + x + 90° + 90° = 900°

5x + 180° = 900°

5x = 900° - 180°

5x = 720°

x = 720°/5

x = 144°

Hence, the angle measurements the carpenter needs to cut the carpet to make it fit in his room are 144°, 144°, 144°, 144°, 144°, 90°, and 90°
