Answer:

Step-by-step explanation:

To find the slope of a line, calculate the distance between points with a ratio of vertical to horizontal distance. This is done using the formula:

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

Here the points are (-7,-2) and (-6,7). Substitute and simplify.

$m=\frac{7--2}{-6--7}=\frac{7+2}{-6+7}=\frac{9}{1}=9$

Solve the equation. Identify any extraneous solutions

Lelu [443]

Squaring both sides of the given equation: w^2=7w, or w^2-7w=0.

w^2-7w=0 can be factored: w(w-7)=0. Then, w=7 or w=0. Both 0 and 7 are solutions of this equation.

What point is a solution to y> 2x -1<br><br> A.(0,2)<br> B.(4,2)<br> C.(0,-10)<br> D.(4,1)

Tom [10]

Well, we need to consider the x and y coordinates of the giben points, and check wether the y coordinate is greater than twice the x coordinate minus 1 (i.e. 2x-1):

For the first point, the x coordinate is 0. So, 2x-1 = -1. The y coordinate is 2, and 2>-1. So, this point is a solution.
For the second point, the x coordinate is 4. So, 2x-1 = 7. The y coordinate is 2, and 2<7. So, this point is not a solution.
For the third point, the x coordinate is 0. So, 2x-1 = -1. The y coordinate is -10, and -10<-1. So, this point is not a solution.
For the fourth point, the x coordinate is 4. So, 2x-1 = 7. The y coordinate is 1, and 1<7. So, this point is not a solution.

Question 2 (1 point)

Papessa [141]

Answer:

55.734 mph

Step-by-step explanation:

Let's call the wind speed x and the time of flight t.

Then, we can write the following equation, knowing that the distance is equal speed times time of flight:

910 = (350+x) * t

660 = (350-x) * t

If we isolate t in both equations and compare its value, we have that:

910 / (350+x) = 660 / (350-x)

(350+x)/(350-x) = 910/660

350 + x = 1.3788 * (350-x)

350 + x = 482.58 - 1.3788x

2.3788x = 132.58

x = 55.734 mph

Vijay missed 12 out of his last 16 free throws. Considering this data, how many of his next 20 free-throw attempts would you exp

PilotLPTM [1.2K]

The fraction computed shows that the number of his next 20 free-throw attempts that you expect Vijay to miss is 15.

<h3>How to solve the fraction?</h3>

From the information given, Vijay missed 12 out of his last 16 free throws. The fraction missed will be:

= 12/16

= 3/4

Therefore, the number of his next 20 free-throw attempts that you expect Vijay to miss will be:

= 3/4 × 20

= 15

The small sign's perimeter is 36 inches

Step-by-step explanation:

The scale factor between two figures is obtained by:

$Scale = \frac{P_{l}}{P_{s}}$

So,

We know that

$Scale= 5:3\\P_l = 60\ in\\$

Putting the values in the above equation of scale factor we get

$\frac{5}{3} = \frac{60}{P_s}$

Cross multiplication

$5 * P_s = 60*3\\5P_s = 180$

Dividing both sides by 5

$\frac{5P_s}{5} = \frac{180}{5}\\P_s = 36$

Hence,

The small sign's perimeter is 36 inches
