Answer:
x = -2Step-by-step explanation:
The slope of q:
[tex]m_q=\dfrac{6-6}{4-6}=0[/tex]
It means the line q is parallel to X-axis. Therefore any line perpendicular to q is parallel to Y-axis.
Any line parallel to Y-axis is: x = x₀, where x₀ is the x-coordinate of any point the line passing through.
(-2, 3) ⇒ x₀ = -2

Answer:
7). x = 6, [tex]\frac{14}{3}[/tex]
8). x = 2
Step-by-step explanation:
7). Area of a circle = πr²
Here 'r' = radius of the circle
Area of the shaded region of the circle = Area of the large circle - Area of the small circle
= π(x)² - [tex]\pi (\frac{x}{2})^2[/tex]
= [tex]\pi x^{2} -\pi (\frac{x^2}{4})[/tex]
= [tex]\pi x^{2}(1-\frac{1}{4})[/tex]
= [tex]\frac{3\pi x^{2} }{4}[/tex] in²
If area of the shaded region is (8πx - 21π) in²
[tex]\frac{3\pi x^{2} }{4}=8\pi x - 21\pi[/tex]
[tex]\frac{3x^2}{4}=8x-21[/tex]
3x² = 32x - 84
3x²- 32x + 84 = 0
3x² - 14x - 18x + 84 = 0
x(3x - 14) - 6(3x - 14) = 0
(x - 6)(3x - 14) = 0
x = 6, [tex]\frac{14}{3}[/tex]
8). Area of the shaded region = Area of the largest circle - Area of the smaller semicircle - Area of the smallest semicircle
Area of the largest circle = π(2x + 2x)²
= 16πx²
Area of the smaller semicircle = [tex]\frac{1}{2}\pi (3x)^{2}[/tex]
= 4.5(πx²)
Area of the smallest semicircle = [tex]\frac{1}{2}\pi (2x)^{2}[/tex]
= 2πx²
Now area of he shaded region = 16πx² - [4.5(πx²) + 2πx²]
= 16πx² - 6.5πx²
= 9.5πx² mm²
If the area of the shaded region = 12πx + 14π
12πx + 14π = 9.5πx²
12x + 14 = 9.5x²
9.5x² - 12x - 14 = 0
19x² - 24x - 28 = 0
19x² - 38x + 14x - 28 = 0
19x(x - 2) + 14(x - 2) = 0
(19x + 14)(x - 2) = 0
x = [tex]-\frac{14}{19},2[/tex]
But the radius o a circle can't be negative.
Therefore, x = 2 will be the answer.

Which function is not linear? A. f(x)=x/4 B. f(x)=2x+1 C. f(x)=-3 D. f(x)=-1/x
Answer:
f(x) = -1/x
Step-by-step explanation:
Here, we want to find the function that is not linear
A linear function is of the form;
y = mx + b
where m can be zero, or b can be zero
The only option that does not follow this description is
f(x) = -1/x

Which expression is equivalent to 2d^2-6/d^2+2d-48 / d-3/2d+16if no denominator equals zero?
Please help. On Pluto
Answer:
B; 4/d-6
Step-by-step explanation:
We want to perform a division here
Flipping the right hand side while changing the sign to multiplication, we have that;
(2d - 6)/ (d^2 + 2d -48) * (2d + 16)/d-3
= 2(d-3)/(d^2 + 2d - 48) * 2d + 16/d-3
= 2/(d^2 + 2d - 48) * 2d + 16/1
2/(d-6)(d + 8) * 2(d + 8)/1
= 2/d-6 * 2/1
= 4/d-6

Kayla thinks that the slope of a vertical line is undefined, while Joshua argues that the slope of a vertical line is zero. Who is correct? *
Answer:
Kayla is correct
Step-by-step explanation:
For a vertical line, the x-value is the same
This means there is no change in the x value
A slope is calculated by dividing by the change in x value
since in this case , we will be dividing by zero, it means that the value of our slope is going to be undefined
This means that Kayla is correct

Answer:
1 Bag = 12.3 Ounces
5 Bags = 61.5 Ounces
123 Ounces = 10 Bags
Step-by-step explanation:
24.6 divided by 2 is 12.3.
12.3 times 5 is 61.5
61.5 times 2 is 123.
You are a space alien. You visit planet Earth and abduct 97 chickens, 47 cows, and 77 humans. Then, you randomly select one Earth creature from your sample to experiment on. Each creature has an equal probability of getting selected. Create a probability model to show how likely you are to select each type of Earth creature. Input your answers as fractions or as decimals rounded to the nearest hundredth.
Answer:
there are 97 + 47 + 77 = 221 creatures from Earth in the alien spaceship.
the probability that a human being is chosen at random = 77 / 221 = 0.3484 = 34.84%
the probability that a chicken is chosen at random = 97 / 221 = 0.4389 = 43.89%
the probability of choosing a cow at random = 100% - 34.84% - 43.89% = 21.27%

Interest = $45
Principal = ?
Interest rate = 3%
Time = 2 years
What interest is this. Simple or compound? Cause both have different formulas.
Simple interest
A(interest) = (Principal× Rate×time)
A= (P ×3×2years)/100%
$45 = 6/100P
4500= 6p
4500/6 = P
principal= $750.
A circular park is 1/3 mile long. Mr. M walks on this track, completing each lap in
1/12 of an hour. What is Mr. M's walking speed? Include the unit of measure.
Answer:
1.7 m/s
Step-by-step explanation:
1/3 mile = 536 m
1/12 hour = 5 minutes = 300 second
volecity = s/t = 536 / 300 = 1.7 m/s
9514 1404 393
Answer:
4 miles per hour
Step-by-step explanation:
Speed is the ratio of distance to time:
speed = miles/hours = (1/3)/(1/12) = (4/12)/(1/12) = 4/1 = 4
Mr. M's walking speed is 4 miles per hour.

Answer:
RS = XY (since the two a triangles are similar, you have to match the sides up and then set the values equal to eachother to find the value of x)
3x +2 = 5x -3 (subtract 5x from both sides)
-2x +2 = -3 (subtract 2 from both sides)
-2x = -5 (divide both sides by -2 to isolate x)
x = 2.5 (take the value of x and plug it into the expression given for RS)
3(2.5) +2 (multiply)
7.5 +2 (add)
9.5 (this is the length of RS)

Arlene has raised $56 for her class field trip. This is $14
more than three times the amount Adam has raised.
Which equation could you use to find how much money
Adam has raised?
Assuming Adams amount is x, three times his amount will be 3x. $14 more than the times Adam's amount will be 14 +3x.
Therefore if Arlene's money is $56 which is $14 more than three times Adam's amount, then the equation will be ;
14+3x=56

Using the Triangle Sum Theorem, please solve for the value of x.
Please type out ALL OF YOUR WORK along with your answer for x. Work is worth 5 points, answer for x is 2 points.
3x
1
12x
55°
Answer:
x = 25
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
2x + 3x + 55 = 180, that is
5x + 55 = 180 ( subtract 55 from both sides )
5x = 125 ( divide both sides by 5 )
x = 25
consider the equation _. determine the steepness in the line between x=1 and x=2.
Answer:
2/3
Step-by-step explanation:
Firstly we get the y value at both x points
At x = 1
y = 2/3 + 1/2 = (4 + 3)/6 = 7/6
At x = 2
y = 4/3 + 1/2 = (8 + 3)/6 = 11/6
The slope formula is
m = (change in y)/change in x
The slope is thus;
(11/6-7/6)/(2-1) = 4/6 = 2/3
