Use the slope formula to find the slope of the line through the points (−2,4) and (0,9).
Answer:
The slope of the line is [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
Hi there!
We are given the following points: (-2, 4) and (0, 9)
We want to find the slope (m) of these 2 lines, and the problem asks us to use the slope formula
The slope formula is given as [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have everything we need to calculate the slope, but let's label the values of the points to avoid any confusion.
[tex]x_1=-2\\y_1=4\\x_2=0\\y_2=9[/tex]
Now substitute these values into the formula to find the slope.
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{9-4}{0--2}[/tex]
Simplify.
m=[tex]\frac{9-4}{0+2}[/tex]
Add (or subtract) the numbers together
m=[tex]\frac{5}{2}[/tex]
The slope of the line is [tex]\frac{5}{2}[/tex]
Hope this helps!

HELP ASAP PLEASE! I need to write an equation in point-slope form of the line that passes through the points below
Step-by-step explanation:
step 1. pick one of the points: (-2, 5)
step 2. calculate the slope of the points (-2, 5) and (1, -1). m = (-1 - 5)/(1 - (-2)) = -6/3 = -2
step 3. plug them in: y - y1 = m(x - x1) = y - 5 = -2(x - (-2)).

Given:
Figure of similar triangles.
To find:
The value of x and the measure of NR.
Solution:
In triangle RST and RMN,
[tex]\angle SRT\cong \angle MRN[/tex] (Vertically opposite angles)
[tex]\angle RST\cong \angle RMN[/tex] (Alternate interior angles)
[tex]\Delta RST\sim \Delta RMN[/tex] (By AA property of similarity)
We know that, corresponding sides of similar triangles are proportional.
[tex]\dfrac{RS}{RM}=\dfrac{RT}{RN}[/tex]
[tex]\dfrac{40}{8}=\dfrac{60}{2x-2}[/tex]
[tex]5=\dfrac{60}{2x-2}[/tex]
[tex]2x-2=\dfrac{60}{5}[/tex]
On further simplification, we get
[tex]2x=12+2[/tex]
[tex]x=\dfrac{14}{2}[/tex]
[tex]x=7[/tex]
The value of x is 7.
Now,
[tex]NR=2x-2[/tex]
[tex]NR=2(7)-2[/tex]
[tex]NR=14-2[/tex]
[tex]NR=12[/tex]
Therefore, the value of x is 7 and the measure of NR is 12 units.

A cell phone provider offers a plan that costs $40 per month plus $0.20 per text message sent or received. A comparable plan costs $70 per month but offers unlimited text messaging.
Answer:
For, 250 messages the plans cost the same. Under 250 messages, plan A is cheaper.
Step-by-step explanation:
Giving the following information:
Plan A:
Fixed costs= $40
Variable cost= $0.2
Plan B:
Fixed cost= $40
I assume that we have to determine the indifference point, where the two plans cost the same.
First, we need to establish the total cost equations
Plan A= 20 + 0.2x
Plan B= 70
x= number of messages
Now, we equal both formulas and isolate x:
20 + 0.2x = 70
0.2x= 50
x= 250
For, 250 messages the plans cost the same. Under 250 messages, plan A is cheaper.
Given the relation y = 3x^2 + 1, if the input is 4, what is the output?
Answer:
Step-by-step explanation:
y=3(4)²+1
=48+1
=49
Answer:
The output is 49
Step-by-step explanation:
If the input is 4, then x = 4.
Replace x with 4 and you have the equation:
3(4)^2 + 1 = 49
Because Y is the output, and Y = 49, the output is 49

The first three terms of a geometric sequence are as follows.
2, 10, 50
Find the next two terms of this sequence.
Answer:
250, 1250
Step-by-step explanation:
Since 10/2 = 50/ 10 = 5, the common ratio = 5 So the next term in the sequence is found by multiplying the last term by 5.
Therefore, 50 x 5 = 250 and 250 x 5 = 1250. So, the next two terms in your sequence are 250 and 1250

Thank you!
Answer:
Step-by-step explanation:
1. The probability that your mail is delivered before 2 pm is 0.9, so the probability that the mail is delivered at 2 pm or after 2 pm (so not before 2 pm) is 1-0.9=0.1.
Remark: 0.9=9/10=90/100=90%, and 0.1 is 10%

Answer:
[tex]E(x) = 4.56[/tex] --- Mean
[tex]s^2 = 1.0944[/tex] --- Variance
[tex]s = 1.0461[/tex] --- Standard Deviation
Step-by-step explanation:
See Comment for missing details
Given
[tex]p = 0.76[/tex] --- proportion
[tex]n = 6[/tex] -- sample
Solving (a): The mean; E(x)
This is calculated as:
[tex]E(x) = n * p[/tex]
Substitute values for n and p
[tex]E(x) = 6 * 0.76[/tex]
[tex]E(x) = 4.56[/tex]
Solving (b): The variance; s^2
This is calculated as:
[tex]s^2 = n*p*(1-p)[/tex]
Substitute values for n and p
[tex]s^2 = 6 * 0.76 * (1-0.76)[/tex]
[tex]s^2 = 6 * 0.76 * 0.24[/tex]
[tex]s^2 = 1.0944[/tex]
Solving (c): The standard deviation; s
This is calculated as:
[tex]s = \sqrt{s^2[/tex]
Substitute value for s^2
[tex]s = \sqrt{1.0944[/tex]
[tex]s = 1.0461[/tex]

Consider the triangle below.
Determine the angle measure for the bottom two angles in order for the triangle to be classified as an isosceles triangle.
Answer:
angle 1= 30 degrees
angle 2= 120 degrees
angle 3= 30 degrees
Step-by-step explanation:
A triangle is equal to 180 degrees so first step is to subtract 120 to get the total of your two missing angles
180-120=60
and since your two missing angles are equal to each other you can divide by 2 and you get your two missing angles
60 / 2 = 30
