Question 3: Solve for x
dmitriy555 [2]

Answer:

<u>-2</u>

Step-by-step explanation:

Solving :

8^{x+2} = 32^{2x+4}

2^{3(x+2)} = 2^{5(2x +4)}

3(x + 2) = 5(2x + 4)

3x + 6 = 10x + 20

10x - 3x = 6 - 20

7x = -14

x = <u>-2</u>

Someone please explain how the GCF of x^4 and x^3 equals x^3. This has me stumped.
Ede4ka [16]

GCF is the greatest common factor. its the value of the factors that are common to both the numbers being compared. In other words the product of the factors that are common to both numbers or the greatest factor common to both numbers.
factors of x⁴ = x * x * x * x = (x * x * x) * x
factors of x³ = x * x * x = (x * x * x)
factors common to both are (x * x * x) Therefore GCF is x³

Triangle ABC has vertices A(–2, 3), B(0, 3), and C(–1, –1). Find the coordinates of the image after a reflection over the x-axis
slava [35]

Answer:

(-2,-3), (0,-3), (-1,1)

Step-by-step explanation:

When reflecting over an axis, the axis you are reflecting over stays the same while the opposite axis becomes its opposite number, like reflect (12, -9) over the y axis, the y (-9) would stay the same but the x (12) would become (-12)
