Which expression is equivalent to _?
Answer:
2^-1
Step-by-step explanation:
2^2 *2 / 2^4
We know that 2^2 * 2 = 2^2 *2^1
a^b*a*c = a^(b+c) so 2^2*2*1 = 2^(2+1)+ 2^3
2^3 / 2^4
We know that a^b / a^c = a^(b-c)
2^3 /2^4 = 2^(3-4) =2^-1
The equivalent of the given expression 2² × (2/2⁴) when simplified is; 2⁻¹
How to simplify exponents?We are given the exponents expression;
2² × (2/2⁴)
Let us first multiply out the numerator to get;
2² × 2 = 2³
Thus, our overall expression is;
2³/2⁴
According to laws of exponents;
a^(b)/a^(c) = a^(b-c)
Thus;
2³/2⁴ = 2³⁻⁴
⇒ 2⁻¹

A rectangular photograph measuring 2 inches by 4 inches is enlarged by a scale factor of 8. What are the new dimensions of the photograph? Can ya explain how you got the answer too?
Answer:
original: 2x4
scale factor: 8
new dimensions:
2x8=16
4x8=32
(To get the new dimensions all you have to do is multiply the sides by the scale factor)
Step-by-step explanation:
The new dimensions of the photograph is [tex]64 \ in^{2}[/tex]
What is a scale factor?The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.
According to the question

Answer:
x = 1.4 or -1.4
Step-by-step explanation:
→ Substitute y = 4 into y = x² + 2
4 = x² + 2
→ Minus 2 from both sides
2 = x²
→ Square root both sides
√2 = x
→ Simplify
x = 1.4 or -1.4

For the equation, determine whether the equation is true for all, some, or no values of x.
Explain how you know.
Answer:
You can check if an equation is true for all some or no values of x by simply to try and solve the equation if you get something like x = x, then the equation is true for all, if you get a specific answer like x=3, then it is true to some values, in simple terms. Try and solve the equation there is no other way to check unless you solve, I don't know if there is another way but this is just my intution.

12y + 16
4*3*y +4*4
Factor out 4
4(3y+4)
Answer:
2(6y+80) = 12y+160
4(3y+4) = 12y+16
28y = 28y
16+12y = 12y+16 (did not use distributive property)
