Answer:

Step-by-step explanation:
Let height of a banner be
, then we know that this is
of the length
of the banner; so we have
.
Now we can rearrange this equation to solve for the length of the banner given it's height:

So there we have it!
If the banner is 5 ft tall, then it's length will be:

Answer:
A graph showing a range of negative three to two on the x and y axes. A dotted line with arrows at both ends that passes through the x axis at two and runs parallel to the y axis. The graph is shaded to the left of the line.
Step-by-step explanation:
The inequality given is x < 2. This means x is less than two are the values that satisfy the equation.
The equation can be written as x=2 to identify the position where the line will pass. The line is dotted and will pass through x=2 to be parallel with the y-axis.
The second and third answers are not correct because the line should not be solid.
The first answer is not correct because the shaded part should be to the left of the line.
Answer/Step-by-step explanation:
1.
; 3
Let's solve for a.
(subtraction property of equality)

(division property of equality)


Therefore, 3 is a solution to 9 = 2a + 3
2.
; 7
(- × - = +)
(Subtraction property of equality)

(division property of equality)

Therefore, 7 is not a solution of 
3.
; 1
Therefore, 1 is a solution of
.
Answer: just simplify condense it then your answer will be log(16)
