Answer: Choice A. (8, 4)
==========================================================
Explanation:
Because x = 2y, we can replace every copy of x with 2y
Let's do so in the second equation
3x - 4y = 8
3(x) - 4y = 8
3(2y) - 4y = 8 .... x replaced with 2y; now let's isolate y
6y - 4y = 8
2y = 8
y = 8/2 ..... divide both sides by 2
y = 4
Use this y value to find x
x = 2y
x = 2*4
x = 8
So we have x = 8 and y = 4 pair together to get the answer (x,y) = (8, 4) which is choice A.
5(x + 1)=20
5x+1=20
????? ASAPPPP
Answer:
x=3
Step-by-step explanation:
5(x+1)=20
5x+5=20
-5 -5
5x=15
now just divide 5 from 15 which is 3 so x=3
Which equation represents a line that passes through (2, -1/2) and has a slope of 3?
A) y-2=3(x+1/2). B)y-3=2(x+1/2)
C)y+1/2=3(x-2)
D)y+1/2=2(x-3)
Answer:
C
Step-by-step explanation:
The line passes through the point (2, -1/2) and has a slope of 3.
We can use the point-slope form, given by:
[tex]y-y_1=m(x-x_1)[/tex]
Where (x₁, y₁) is a point, and m is the slope.
Let (2, -1/2) be (x₁, y₁). We will substitute 3 for m. Therefore:
[tex]\displaystyle y-\Big(-\frac{1}{2}\Big)=3(x-(2))[/tex]
Simplify:
[tex]\displaystyle y+\frac{1}{2}=3(x-2)[/tex]
Therefore, our answer is C.

Suppose f(x) = x2 and g(x) = Which statement best compares the graph of g(x) with the graph of f(x)?
Answer:
g(x) is horizontally stretched by a factor of 1/5
Step-by-step explanation:
Given
[tex]f(x) = x^2[/tex]
[tex]g(x) = (\frac{x}{5})^2[/tex]
Require
Determine the relationship between f(x) and g(x)
[tex]f(x) = x^2[/tex]
[tex]g(x) = (\frac{x}{5})^2[/tex]
Express g(x) in terms of f(x)
[tex]g(x)=f(\frac{x}{5})[/tex]
This can further be simplified as:
[tex]g(x)=f(\frac{1}{5}x)[/tex]
When a function is represented as:
[tex]g(x) = f(cx)[/tex]
Where c < 1,
Then the type of translation is a horizontal stretch (stretch in the x direction)
By comparison: [tex]g(x) = f(cx)[/tex] and [tex]g(x)=f(\frac{1}{5}x)[/tex]
[tex]c = \frac{1}{5}[/tex]
This means that: g(x) is horizontally stretched by a factor of 1/5

Guys I really need help this is due and I have been on this question for 2 hours.
5. Reflection: Marissa wants to describe the relationship between the scale factor and perimeter of an image and its pre-image and between the scale factor and area of an image and its pre-image. What should she say about the relationship between the scale factor and perimeter of an image and its pre-image? What should she say about the relationship between the scale factor and the area of an image and its pre-image?
Answer:
see below
Step-by-step explanation:
Answer in your own words:
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape. Which can also be used to calculate the dimensions of the new figure or the original figure by simply substituting the values in the same formula.
• The scale factor of a dilated figure is denoted by 'r' or 'k'.
• If the scale factor is more than 1 (k > 1), the image is enlarged.
• If the scale factor is less than 1 (0< k <1), the image is contracted.
• If the scale factor is 1 (k = 1), the image remains the same.
• The scale factor cannot be zero.
Scale factor = k
Pre-image lengths: a, b
(perimeter = 2a + 2b)
Image lengths: ka, kb
(perimeter = 2ka + 2 kb or k (2a + 2b))
Marissa needs to say that the perimeter of the image is the perimeter of the pre-image times the same scale factor.
area of the pre-image = ab
area of the image = (ka)(kb) or k^2 (ab) (The area of the image is the area of the preimage times the square of the scale factor)
Scale factor 5 (then repeat it with scale factor 6)
length of the pre-image = 3 x 4
(perimeter = 2 (3 + 4) = 2(7) = 14)
length of the image = (3x5) x (4x5) = 15 x 20= 300
(perimeter = 2 (15 + 20) = 2 (35) = 70 or 14 x 5 = 70
area of the pre-image = 3 x 4 = 12
area of the image = 15 x 20 = 300
12 x (5^2) = 12 x 25 = 300
