Answer:
A
Step-by-step explanation:
So lets look at the points on the graph.
Actually, lets just look at a and b(We only need 1 of these points, but it doesnt hurt to do a little extra to udnerstand it better)
If we count the coordinates for A, we get:
(-2, 3)
Remember, we need to use a scale factor of 2 for this.
So we need to multiply by 2.
This now gets us:
(-4. 6)
This looks like answer A, which has: (-4, 6) for A coordinates.
Now, lets check this with B coordinates:
(1, 3)
Multiply by 2:
(2, 6)
For answer A, is this the B coordinates?
Yup, answer A has B coordinates (2, 6)
So the answer is A!
Hope this helps! :)

Answers
Answer:
The area of the circle is equal to [tex]9\pi[/tex].
Step-by-step explanation:
Given that,
The area of sector is, [tex]\dfrac{17}{2}\pi[/tex]
The central angle is [tex]\dfrac{17}{9}\pi[/tex]
We need to find the area of circle.
We know that,
[tex]\text{Area of sector}=\dfrac{\text{central angle}}{2\pi}\times \text{Area of circle}\\\\\text{Area of circle}=\dfrac{2\pi \times \text{Area of sector}}{\text{central angle}}\\\\=\dfrac{2\pi \times \dfrac{17\pi}{2}}{\dfrac{17\pi }{9}}\\\\=9\pi[/tex]
So, the area of the circle is equal to [tex]9\pi[/tex].

Combine like terms in 3x + 2y + 2x + 4y + 1
Answers
Answer: 5x+6y+1 is the answer
Step-by-step explanation: to combine like terms that have to have the same variable so you can add them so for example you have 3x+2x which is equal to 5x then 2y+4y which is = to 6y and you also have 1 that isn't adding to anything because the others have variables
Answer:
5x + 6y + 1
Step-by-step explanation:
You are also simplifing and collecting the like terms. 3x + 2x = 5x. So that goes first as it appears first in the equation. Secondly, 2y + 4y = 6y, and that adds on to the previous answer. So far we have 5x + 6y. Now just add te 1, as it has no like value.

pi = 3.14
To find : Circumference ( circle ) = ?
Radius ( r )
= Diameter / 2
= 20 / 2
= 10 ft
Formula : -
Circumference ( circle ) = 2 pi r
Circumference ( circle )
= 2 x 3.14 x 10

Answers
Answer:
Step-by-step explanation:
The negative out front only tells us which way the parabola will open. That means that the first one will open upside down, since it's got a negative out front. The value of the number that serves as the leading coefficient (the number stuck to the x-squared) determines how steep or wide-open the parabola's shape is. The leading coefficient in the first one is a 1, so it opens up exactly as wide as its parent graph does. The leading coefficient in the second one, a 2, means that the parabola will be skinnier or narrower than its parent. If the leading coefficient is greater than 1, the parabola will be narrower than its parent; if the leading coefficient is greater than 0 but less than 1, the parabola will open wider than its parent.

You randomly select 2 marbles from a mug containing 7 blue marbles, 3 red marbles, and 2 white marbles. How many times greater is the probability of selecting one blue marble and then one red marble when you do not replace the first marble before selecting the second marble than when you do replace the first marble before selecting the second marble? Express the answer as a fraction.
Answers
Answer:
Scenario 1: w/o replacement: P(blue, then red) = (7/12)(3/11) = 7/44
Scenario 2: w/ replacement: P(blue, then red) = (7/12)(3/12) = 7/48
Ratio of Probability #1 to Probability # 2 = 48/44 = 12/11, i.e. Prob # 1 is 1.0909... times Prob # 2

What is the amplitude of the graph of y = 2sin(4x - 1) + 3 ?
Answers
Answer: 2
Step-by-step explanation:
The amplitude of the function of graph y = 2sin(4x - 1) + 3 is 2.
What is the graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
What is function?The function is defined as mathematics expression defines a relationship between one variable and another variable.
What is the amplitude of function?A amplitude of function is defined as periodic variable's amplitude is a measure of its change over a single period. A non-periodic signal's magnitude in relation to a standard value is its amplitude.
Given the function of graph as :
y = 2sin(4x - 1) + 3
Comparing the form asin(bx - c) + d to determine the amplitude, period, phase shift, and vertical shift.
Where a is amplitude , d is vertical shift , c/b is phase shift
Amplitude (a): 2
Period: π/2
Phase Shift (c/b): 1/4 (1/4 to the right)
Vertical Shift (d) : 3
Hence, the amplitude of the function of graph y = 2sin(4x - 1) + 3 is 2.

The solution to the system is (3,4):
3x – 2y = 1
4y = 7+3x
Pizz help mee
Answers
Answer:
(3,4) is the solution of both equations.
Step-by-step explanation:
The given equations are :
3x – 2y = 1 ....(1)
4y = 7+3x
4y-3x = 7 .....(2)
Put x = 3 and y = 4 in equation (1).
3(3) – 2(4) = 9-8
= 1
So, (3,4) is the solution of the equation (1).
Again put x = 3 and y = 4 in equation (2).
4(4)-3(3) = 16-9
= 7
Hence, (3,4) is the solution of both equations.
