What is the slope of the line that passes through (3, −7) and (−1, 1)? (1 point)
Answer:
The slope of the line is -2
Step-by-step explanation:
The rule of the slope of a line is:
[tex]m=\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 two points on the line
Let us find the slope using the rule above
∵ The line passes through points (3, -7) and (-1 , 1)
∴ [tex]x_{1}[/tex] = 3 and [tex]x_{2}[/tex] = -1
∴ [tex]y_{1}[/tex] = -7 and [tex]y_{2}[/tex] = 1
Substitute these values in the rule above to find m
∴ [tex]m=\frac{1--7}{-1-3}=\frac{1+7}{-4}=\frac{8}{-4}=-2[/tex]
∴ The slope of the line that passes through the given points is -2
Need help with this problem!! Point X is the midpoint of HI. What is the coordinate of the point X?
Answer:
1
Step-by-step explanation:
The midpoint is the average of the points H and I
midpoint = | [tex]\frac{-2+4}{2}[/tex] | = | [tex]\frac{2}{2}[/tex] | = | 1 | = 1
The following equation defines f(x)=-3x-5 . If (-5,n) is an ordered pair of the function rule, what is the value of n?
Given:
The function is
[tex]f(x)=-3x-5[/tex]
(-5,n) is an ordered pair of the function rule.
To find:
The value of n.
Solution:
If (-5,n) is an ordered pair of the function rule, then the function must be satisfied by the point (-5,n). It means f(-5)=n.
Substitute x=-5 in the given function.
[tex]f(-5)=-3(-5)-5[/tex]
[tex]f(-5)=15-5[/tex]
[tex]f(-5)=10[/tex]
We know that, [tex]f(-5)=n[/tex]. So,
[tex]n=10[/tex]
Therefore, the value of n is 10.

[tex]62+67=129\\m<1=129[/tex]
6b)
[tex]180-152= 28\\28+115=143\\180-143=37\\m<1=37[/tex]
Answer:
Step-by-step explanation:
6a. inside the triangle:
x + 62 + 67 = 180
x + 129 = 180
x = 51
For <1: m<1 + 51 = 180
m<1 = 129
6b. for next to the exterior:
x + 152 = 180
x = 28
Inside the triangle:
m<1 = m<1 + 28 + 115 = 180
m<1 + 143 = 180
m<1 = 37

Select the correct choices to complete the sentence. Three drivers competed in the same fifteen drag races. The mean and standard deviation for the race times of each of the drivers are given. Driver A had a mean race time of 4.01 seconds and a standard deviation of 0.05 seconds. Driver B had a mean race time of 3.96 seconds and a standard deviation of 0.12 seconds. Driver C had a mean race time of 3.99 seconds and a standard deviation of 0.19 seconds. a. Which driver had the fastest typical race time?
Answer:
Driver B has the fastest race timeStep-by-step explanation:
From the options presented, driver B has the fastest typical race time because he recorded the smallest time taken to complete an individual race.
Also from the standard deviation given (3.96) for driver B, it shows that the individual time spread from the standard deviation is minimal and that the driver maintained a fairly consistent time of race throughout the racing period.

A solution is prepared by dissolving
24 milliliters of saline in 150 milliliters of pure
solution. What is the percent of saline in the pure
solution?
Answer:
13.79%
Step-by-step explanation:
A solution is made by dissolving 24 millimeters of saline in 150 millimeters of pure solution
Therefore percent of saline in the pure solution can be calculated as follows
= 24/24+150 × 100
= 24/174 ×100
= 0.1379 ×100
= 13.79%
Hence the percent of saline in the pure solution is 13.79%

In a city with three high schools, all the ninth graders took a Standardized Test, with these results:High Scool Mean Score test Number of ninth gradeGlenwood 79 285Central city 94 336Lincoln High 72 191The city's PR manager, who never took statistics, claimed the mean score of all ninth graders in the city was 81.7 . Of course, that is incorrect. What is the mean score for all ninth graders in the city? USE EXCEL. Round your answer to one decimal place.
Answer: 83.56
Step-by-step explanation:
To calculate the mean score for all ninth graders in the city, we multiply the mean score test for each school by the number of months grade students and then add all together and divide by the total ninth grade students. This is solved below.
Mean = [(79 × 285) + (94 × 336) + (72 × 191)]/285+336+191
= (22515+31584+13752)/812
= 67851/812
= 83.56

Answer:
x = 124°y = 88°z = 92°Step-by-step explanation:
find:
1) x
2) y
3) z
solve for x:
1) opposite angle are equal.
x = 124°
solve for y:
2) inside angle of a triangle = 180
180 = 53 + 39 + y
180 - 53 - 39 = y
y = 88°
solve for z:
3) z + y = 180
substitute y = 88
z + 88 = 180
z = 180 - 88
z = 92°

Below is a typical Geometric Two-Column Proof that you will be able to complete by the end of your Geometry course. But right now you only have a few postulates and theorems in your Geometry toolbox. Using what you already know about the Vertical Angles Theorem, fill in Step 3 of this proof.
A. ∠A≅∠D
B. ∠AMB≅∠DMC
C. ∠ABM≅∠DCM
D. ∠C≅∠B
Answer:
the answer is B.
Step-by-step explanation:
since the M is the middle point of the angles AB and DC.
we just add the M in the middle.
also i did the test and got it right, soooo im 100% sure its B
This is about understanding vertical angles theorem.
Option B is Correct
Vertical angles theorem is an angle theorem that states that when two lines intersect each other, the two opposite vertical angles formed will always be congruent i.e equal to each other.Looking at the image, we can see that the two lines that intersect each other are Line AD and Line BC.
The two opposite angles they form are; ∠AMB and ∠DMC.
Now, from the vertical angles theorem quoted above, we can say that;∠AMB is congruent to ∠DMC.
The congruency symbol is ≅.
Thus; ∠AMB ≅ ∠DMC.

X-7/4=y
F-1(x)=x-7/4
The inverse of the function is y = (x-7)/4 , the steps are correctly ordered.
What is an Inverse Function?An Inverse function is found when the variables x and y are interchanged in the f(x,y) function and then the equation is solved for y.
The function is
f(x)= 4x+7
y = 4x+7-------- Step 7
y-7 = 4x--------Step 2
x = 4y +7------ Step 3
x - 7 = 4y------- Step 6
(x-7)/4 = y------- Step 4
f⁻¹ (x) = (x-7)/4------- Step 5
