[tex]\huge\boxed{\sf{Und.efined}}[/tex]
Step-by-step explanation:
Hello.
There are 2 ways to solve this problem.
One of them is to use the slope formula.
The other one is to simply look at the x-coordinates and see that they are the same.
This means the slope is undefined.
I hope it helps.
Have a great day.

positive slope and a negative y-intercept?
A. y = 1.75x
B. y = 2/3x - 1
C. y = -4x + 7
D. y = -0.5-1
Answer:
B
Step-by-step explanation:
the 2/3x represents how much it will increase while the -1 represents the y-intercept
Line K has the equation y=5x-4.
Line L is parallel to line K, but passes through the point (-2,-7).
The equation for L in slope-intercept form is: ______
Explanation:
Parallel lines always have equal slopes, but different y intercepts.
Line K has a slope of 5, which means line L also has this slope too. Refer to the y = mx+b form.
Plug in the coordinates of (-2,-7) as well as the slope mentioned and solve for b.
y = mx+b
-7 = 5(-2) + b
-7 = -10+b
-7+10 = b
3 = b
b = 3
The y = mx+b updates to the final answer of y = 5x+3

Sam bought some apples at 60c each and sold all but 5 of them at R1,00 each. If he made a profit of R5,00, how many apples did he buy?
Answer:
5
Step-by-step explanation:
The number of apples bought by him is 113.
What is an expression?A grouping of variables, symbols, and/or numbers used to represent a mathematical quantity or relationship is known as an expression in mathematics. Expressions might be straightforward with just one number or variable or complex with many terms, operations, and functions.
Let's assume that Sam bought x number of apples.
He bought them at 60 cents each, which means the total cost of buying these apples was:
Cost price = 60x cents
He sold all but 5 of these apples at R1.00 each, which means the total revenue he earned from selling them was:
Revenue = (x - 5) x R1.00 = R(x - 5)
Sam made a profit of R5.00, which means his revenue was more than his cost price by R5.00. We can write this as:
Revenue - Cost price = R5.00
Substituting the values of revenue and cost price from above, we get:
R(x - 5) - 60x = 500 cents
Rearranging and simplifying this equation, we get:
40x = 500 + 5R
Substituting R = R1.00, we get:
40x = 500 + 5 = 505
Solving for x, we get:
x = 12.625
Since Sam cannot buy a fraction of an apple, we round up x to the nearest integer:
x = 13

What is the volume of a cylinder with a height of 14.6M and a base with a diameter of 18.2M, to the nearest chance of cubic meter
_________ M^3
Answer:
3796.34164m^3
Step-by-step explanation:
you first need to find the radius of the circle that is the top by dividing 18.2 in two. then you need to square it to find the area of that portion of the circle. then multiply it by 3.14 or pi. then after you do all that you should get 82.81m^2. after that you multiply it by the height of the cylinder which is 14.6m. after that you have your answer of 3796.34164m^3. this might be a little bit off so I recommend using pi.

How could you use a random number generator with the digits 0 to 9 to simulate the scenario?
Answer:
In Matlab, the command rand(1) returns a random number between 0 and 1 assuming uniform distribution. We can build other random variables using rand. For example, to get a random number between a and b we can use a+rand(1)(b − a). To get a 0 or 1 on a random way in Matlab, you can use round(rand(1)).
Step-by-step explanation:
Answer: Here's one possible simulation:
The probability of Americans exercising the given amount is 50%, which means that the probability of Americans not exercising the given amount is also 50%. In other words, the ratio of Americans who exercise the given amount to those who don’t is 1 : 1. Simulate this situation using a random number generator where the numbers 0 to 4 represent a person who exercises the given amount and the numbers 5 to 9 represent a person who doesn’t. Generate sets of three numbers, one for each person. If all three of the numbers are between 5 and 9, this result would mean all three people do not exercise as much as 50% of Americans do.

The two true statements for the expansion are A and C.
Which statements are true?In the expansion of (x + y)ⁿ, each one of the terms will have a total exponent equal to n, this means that we will have terms like:
[tex]x^k*y^j[/tex]
Such that k + j = n.
Particularly, we get the terms xⁿ and yⁿ only once, so the first statement is correct, the coefficients of these terms will be 1.
It is also true that the coefficients of:
[tex]x^k*y^j = x^k*y^k[/tex]
Are equal.
Then the two true statements are A and C.

Answer:
1) 27/2 2) 8pi 3) 48 4) 16+2pi
Step-by-step explanation:
1) The length of the triangle is 9 (found by finding the distance between (-5,-3) and (4,-3)) and the height is 3 (found by finding the distance between (1,0) and (1,-3)). The area of a triangle is 1/2 (length times height) which in this case is 27/2.
2) The shape is a semicircle, so the area is 1/2 pi*r^2.
1/2 * pi * r^2=8pi
3) B*H=8*6=48
4) The figure is a semicircle and a square.
The area of the semicircle is 1/2 * pi * r^2=2pi
The area of the square is b*h=4*4=16
The area is 16+2pi.

Find the surface area 9 cm 6 cm 6 cm
Answer:
144cm²
Step-by-step explanation:
The surface area of a shape = area of all the sides added together
area of bottom side (square) = 6 x 6 = 36
area of triangles = [tex]\frac{1}{2}[/tex] x 6 x 9 = 27
27 x 4 =108
108 + 36 = 144
Answer:
[tex]A_{total} = 144\ cm^2[/tex]
Step-by-step explanation:
Step 1: Determine the area of the bottom square
[tex]A = l * w[/tex]
[tex]A = 6\ cm * 6\ cm[/tex]
[tex]A = 36\ cm^2[/tex]
Step 2: Determine the area of the triangle
[tex]A= \frac{h *b}{2}[/tex]
[tex]A=\frac{9\ cm * (6\ cm/2)}{2}[/tex]
[tex]A=\frac{9\ cm * 3\ cm}{2}[/tex]
[tex]A=13.5\ cm^2[/tex]
Since we have two of these right triangles on each side we come out to having 8 of these triangles total since we have 4 sides. We multiply 8 by our area from one triangle.
[tex]A=13.5\ cm^2*8[/tex]
[tex]A = 108\ cm^2[/tex]
Step 3: Determine the surface area
[tex]A_{total} = 36\ cm^2 + 108\ cm^2[/tex]
[tex]A_{total} = 144\ cm^2[/tex]

solve for x. round to the nearest tenth
Answer:
43.1

We can figure this out by using a bit of simple trigonometry
Using the available values we know we have to figure out x using cos because it includes the adjacent and hypotenuse values.

Cos(x) = Adjacent / Hypotenuse
Cos(x) = 8/11
Cos(x) = 0.73

Step-by-step explanation:

Answer: These triangles are NOT similar. If these triangles were similar, all the angles would have to be equal. Therefore, the angles in each triangle would be 47, 56, and 71 degrees. When we sum 47 + 56 + 71, we get 174 which is not equal to 180 degrees. Therefore, these triangles are NOT similar.

Here are the prices 4 cheese pizza at a certain pizzeria:
pizza size price in dollars
small. 11.60
medium
large. 16.25
a)You had a coupon that made the price of a large pizza $13.00. For what percent off was the coupon?
b) Your friend purchased medium pizza for $10.31 with a 30% off coupon. what is the price of a medium pizza without a coupon?
c) Your friend has a 15% off coupon and $10. what is the largest pizza that your friend can afford?
Step-by-step explanation:
a)
100% = 16.25
1% = 100%/100 = 16.25/100 = 0.1625
the discount was $16.25 - $13.00 = $3.25.
how many % is that ?
well, it is a many % as how many times 1% (0.1625) fits into 3.25.
so,
3.25 / 0.1625 = 20
therefore, the coupon was for 20% off.
b)
30% off means he paid 70% of the normal price.
70% = 10.31
1% = 70%/70 = 10.31/70 = 0.147285714...
100% = 1%×100 = 0.147285714... × 100 = 14.72857143...
so, rounded to the nearest cent the normal price for a medium pizza is $14.73
FYI - the direct method would be to divide the discounted price by the %, so, 10.31 / 0.7 ≈ 14.73
but the reason for this shortcut is in the detailed steps explained above.
c)
as we have seen in a) and b), a large pizza after 20% discount is $13, and a medium pizza after 30% discount is $10.31. both is too much for the available $10 (and even less discount).
so, the only chance is a small pizza.
15% discount means to pay 85%.
100% = 11.6
1% = 0.116
85% = 1%×85 = 9.86
he can afford max. a small pizza after 15% discount for $9.86 with his $10.
to calculate in the other direction : with a 15% coupon it means
85% = 10
1% = 10/85 = 0.117647059...
100% = 1%×100 = 11.76470588... ≈ 11.76
with a 15% coupon and $10 he can afford to buy something with a normal prize of max. $11.76
