Answer:
The first one is equivalent [the 6x+48 = 2(3x+24)] and the second one is <u>NOT</u> equivalent [the 7x+21 ≠ 2(5x+3)]
Step-by-step explanation:
Just follow distributive property to solve these. You can ignore the first expression in both until you have to compare the answers.
1. 6x+48 and 2(3x+24)
2(3x+24) ---> 2(3x) + 2(24) ---> <u>6x + 48</u>
Bring in the first expression ~ <u>6x+48 and 6x+48 </u>
They are the same, so they are equivalent
2. 7x+21 and 2(5x+3)
2(5x+3) ---> 2(5x) + 2(3) ----> 10x + 6
Bring in the first expression ~ <u>7x+21 and 10x + 6</u>
They are NOT the same, so they are NOT equivalent
A is quadratic function
B is equation of a circle
C is equation of a line
D is hiperbolic funciotn
By using the base change formula, which states

The given equation is 
By substituting the values of log 5 and log 3.

= 1.46

Answer:
3x -y = -5
Step-by-step explanation:
The parallel line will differ only in the constant. The new constant can be found by filling in the x- and y-values for the given point.
3x -y = 3(-4) -(-7) = -12 +7
3x -y = -5
