Answer:
y = x/4
Step-by-step explanation:
Use point (4, 1).
y = kx
1 = k * 4
k = 1/4
y = 1/4 x
y = x/4
What are the vertices of the image r(90°, O) (△BCD)?
A. B'(−3, −3), C'(−1, 4), D'(2, 0)
B. B'(3, 3), C'(1, −4), D'(−2, 0)
C. B'(3, −3), C'(1, 4), D'(0, 2)
D. B'(−3, −3), C'(−1, −4), D'(0, −2)
Answer:
The correct option is;
A. B'(-3, -3), C'(-1, 4), D'(2, 0)
Step-by-step explanation:
The given coordinates of the vertices triangle ΔBCD, are;
B(-3, 3), C(4, 1), D(0, -2)
The transformation to be performed is r(90°, 0) (ΔBCD) which is a 90 degrees counterclockwise rotation about the origin
The rule for transformation of a geometric figure by rotation of 90 degrees counterclockwise is given as follows;
The coordinates of the preimage (x, y), the coordinates of the image (-y, x)
Therefore, we have;
The preimage B(-3, 3), the coordinates of the image after 90 degrees counterclockwise rotation is B'(-3, -3)
Similarly, we have;
The preimage C(4, 1), the coordinates of the image after 90 degrees counterclockwise rotation is C'(-1, 4)
For the point D, we have;
The preimage D(0, -2), the coordinates of the image after 90 degrees counterclockwise rotation is D'(2, 0)
Therefore, the correct option is B'(-3, -3), C'(-1, 4), D'(2, 0).

To solve for G(f(4))
First replace x with 4 in the equation of f(x), use the solution to replace x in g(x).
F(x) = -4x + 10
= -4(4) + 10
= -16 + 10
= -6
Now replace x in the equation of g(x) with -6
G(x) = x^2 + 7x + 5
= (-6)^2 + 7(-6) + 5
= 36 -42 + 5
= -1
The answer is -1
Riverside and Fresno are 36 cm apart on a map. The map has a scale of 2 cm = 15 miles. How many miles apart are Riverside and Fresno?
Answer:
270 miles
Step-by-step explanation:
36/2=18. So 18 times of 15 miles = 270
Which of the following statements is TRUE about minor sectors?
The central angle of a minor sector is equal to 180°.
The central angle of a minor sector is less than 180°.
The central angle of a minor sector is greater than 270°.
The central angle of a minor sector is equal to 360°.
The statement "The central angle of a minor sector is less than 180°" is true option second is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
As we know,
In the circle, if the central angle is less than 180 degrees then the sector is known as a minor sector.
The definition of the minor sector also says that "the central angles of a minor sector is less than 180"
Thus, the statement "The central angle of a minor sector is less than 180°" is true option second is correct.

The concession stand at a ballpark makes $0.43 profit from each hot dog sold. It also makes a profit of $0.65 from each pretzel sold and $1.31 from each drink sold. Which expression represents the total profit, in dollars, that the stand will make on a day when they sell h hot dogs, p pretzels, and d drinks? 2.39 (h + p + d) 0.43 h + 0.65 p + 1.31 d (0.43 h) (0.65 p) (1.31 d) (0.43 + h) (0.65 + p) (1.31 + d)
Answer: 0.43h + 0.65p + 1.31d
Step-by-step explanation:
Profit made from each hotdog sold = $0.43
Profit made from each pretzel sold = $0.65
Profit made from each drink sold = $1.31
Number of hotdogs sold = h
Number of pretzels sold = p
Number of drinks sold = d
Total profit made will then be the profit for each multiplied by the number of things sold. This will be:
= ($0.43 × h)+($0.65 × p)+($1.31 × d)
= 0.43h + 0.65p + 1.31d

Chloe is replacing three different sections of her of the fence in her backyard she needs fencing and length of 13 yards for 17-year-olds in 20 yards how much fencing does she need in feet
Answer:
150 feet
Step-by-step explanation:
Here is the complete question
Chloe is replacing three different sections of her of the fence in her backyard she needs fencing and length of 13 yards, 17-yards and 20 yards. How much fencing does she need in feet
Solution
To find the total number of fencing Chloe needs in feet, we first add up the amount she needs in yards and then convert it to feet. Since she needs fencing and length of 13 yards, 17-yards and 20 yards, the total length of fencing she needs in feet is L = 13yards + 17 yards + 20 yards = 50 yards.
We now convert 50 yards to feet, Since 1 yards = 3 feet, 50 yards = 50 × 1 yard = 50 × 3 feet = 150 feet.
So Chloe needs 150 feet of fencing.

A. 6e + 3f + 4
A. 6e
B. 6e + 7f + 8
C. 2e + 7 + 4
D. 2e + 3f + 8
Answer:
The answer is D. 2e + 3f + 8
Step-by-step explanation:
4e + 6 -2e + 5f + 2 - 2f 1. We combine like terms
4e -2e + 6 + 2 + 5f - 2f
2e + 8 + 3f OR 2e + 3f + 8

--9 m-
->
1. Perimeter
=
2. Area =
Answer:
Perimeter - 24 m
Area - 27 m^2
Step-by-step explanation:
The perimeter of a shape can be solved by 2(length) + 2(width)
The length is 3 and the width is 9 so we can use those numbers instead
2(3) + 2(9) = 6 + 18 = 24 m = perimeter
To solve the area you have to multiply the length by the width.
The length is 3 and the width is 9 so we multiply those together
3*9 = 27 m^2
Hope this Helps!!! :)
Let me know if I should change anything about my answer or if this was very helpful!!! Thanks!!!
are natural numbers closed under subtraction
The natural numbers are "closed" under addition and multiplication. ... The subtraction of two natural numbers does NOT necessarily create another natural number (3 - 10 = -7). The division of two natural numbers does NOT necessarily create another natural number (1 ÷ 2 = ½). not closed under subtraction and division.

If you take a look at the point, each one goes up 1 and over 3. The slope is negative because the line is going to the left.
Which value of a correlation coefficient represents the strongest relationship between the two variables in a given linear regression model?
a) -0.94
b) 0
c) 0.5
d) 0.91
Explanation:
The closer r gets to +1 or -1, the stronger the linear relationship will be.
If r is really close to +1, then we have a strong positive linear relationship. If r is close to -1, then we have a strong negative linear relationship.
Of the four choices given, we see that r = -0.94 is the closest to either endpoint mentioned. The next closest is r = 0.91
Put another way, we're looking for the r value that is furthest way from 0, but also that makes the inequality [tex]-1 \le r \le 1[/tex] true. Choice A fits that description best.
During summer vacation, Juan traveled a total distance of 900 miles. His trip took 12 hours. What was the average speed during the trip in miles per hour (mph)? Show your work for full credit!
Answer:
75 miles per hour
Step-by-step explanation:
In order to find the answer, you have to use the formula to calculate the speed:
s=d/t
s=speed
d=distance traveled= 900 miles
t=time elapsed= 12 hours
Now, you can replace the values in the formula:
s=900 miles/ 12 hours
s=75 miles per hour
According to this, the answer is that the average speed during the trip was 75 miles per hour.
Use the table to determine the degree of the power function. What is the degree of the power function.
Answer:
The degree of the power function is 3
Step-by-step explanation:
Let the power function be f(x) = b × xᵃ
Therefore, from the table, we have;
40 = b × (-2)ᵃ
5 = b × (-1)ᵃ
0 = b × 0ᵃ
-5 = b × (1)ᵃ
-40 = b × (2)ᵃ
From -5 = b × (1)ᵃ, we have;
1ᵃ = 1, which gives;
-5 = b × 1
b = -5
From -40 = b × (2)ᵃ, where b = -5, we have;
-40 = -5 × (2)ᵃ
(2)ᵃ = -40/(-5) = 8
(2)ᵃ = 8 = (2)³
∴ a = 3
㏑(2)ᵃ = ㏑(8)
a·㏑(2) = ㏑(8)
a = ㏑(8)/(㏑(2)) = 3
a = 3
The power function is f(x) = -5 × x³
∴ The degree of the power function is 3.

How do I do this step by step
Answer:
-1
Step-by-step explanation:
1. You would get rid of the denominator -> Which would be 2
2. You would then multiply both sides by 2
This gets you: 2x + 22 = 20
3. You then would combine like terms -> Subtract the 22 to the side of the 20
This would get you the value of 2x = -2
4. Solve for X which gets you -1
