Step-by-step explanation:
b. Does a12 x a4 = a8 x a8 for all values of a? Explain.
Answer:
We can use the Laws of Exponent to rewrite both sides of the equation:
Let a¹² x a⁴ = a⁸ x a⁸
⇒ a¹²⁺⁴ = a⁸⁺⁸
a¹⁶ = a¹⁶ ✅
⇒ a¹² x a⁴ = a⁸ x a⁸ is true for all values of a.
Explanation:
The equation a¹² x a⁴ = a⁸ x a⁸ is true because, on both the RHS and LHS of the equation, both terms in 'a' have exponents that when added (Law of Multiplication of Exponents) are equal to each other, i.e. 12+4 = 8 + 8.
Solve 2x - 4 > 10 and select all of the following answer choices that would make this inequality true. A)9 B) 5 C) 6 D)8
Answer:
x > 7

lols ppz help1/2 (2 1/2×4 4/5-7 1/2)????,,,,,
Answer:
If you've written it correctly, the answer is 2.25.
Step-by-step explanation:
Can be written as:
0.5 * (2.5 * 4.8 - 7.5).
Perform the multiplications inside the brackets, first:
0.5 * ( 12 - 7.5)
Then perform the remaining arithmetic inside the brackets:
0.5 * ( 4.5)
Perform the last arithmetic:
2.25.
Again, that's if you've written it correctly, and when you say 4 4/5-7 1/2 this actually means four and four fifths (4.8) minus seven and a half (7.5).

Answer: -5 and -7
Step-by-step explanation:
|[tex]\frac{x}{2}[/tex]+3| = [tex]\frac{1}{2}[/tex]
It has 2 cases
the first case ;
[tex]\frac{x}{2}[/tex] + 3 = [tex]\frac{1}{2}[/tex]
[tex]\frac{x}{2}[/tex] = [tex]\frac{-5}{2}[/tex]
x = -5
the second case;
[tex]\frac{x}{2}[/tex] + 3 = [tex]\frac{-1}{2}[/tex]
[tex]\frac{x}{2}[/tex] = [tex]\frac{-7}{2}[/tex]
x = -7

2.) Use rigid motions to explain whether the triangles in the graph are congruent.
What are the coordinate rules that were used to map one triangle to the next?
1st rule:
2nd rule:
Answer:
1st rule: Reflection over the X-axis, (x,y) -> (x , -y)
2nd rule: Horizontal translation to the RIGHT 6 units (x , -y) -> (x+6 , -y)
Step-by-step explanation:
1st rule: Reflection over the X-axis, (x,y) -> (x , -y)
2nd rule: Horizontal translation to the RIGHT 6 units (x , -y) -> (x+6 , -y)
MJS: (4,-4) (-2,-3) (-3,1) -> (-4,4) (-2,3) (-3,-1) -> (2,4) (4,3) (3,-1)
They are congruent!!
Rectangle PROM has a perimeter of 42 inches, and OR = 8 inches. What is the area of the rectangle PROM?
Answer:
104 in²
Step-by-step explanation:
If OR = 8 then 8 x 2 = 16
PM= (42-16)/2=13
Therefore area = 8 x 13 = 104 in²
To check the perimeter is right:
2(8+13) = 42
