Find the y-intercept of each line defined below and compare their values
1 answer:
Answer:
The y-intercept of Line A is 2 and the y-intercept of Line B is -6.
Therefore, the y-intercept of Line A is greater than y-intercept of Line B
Step-by-step explanation:
We need to find y-intercept of both lines A and B
Equation of Line A
The equation is in slope intercept form where m is slope and b is y-intercept.
Comparing both equations we get b = 2
So, y-intercept of Line A is 2
Graph for Line B
From the graph, the y-intercept can be found by putting x =0.
Looking at the graph, when x =0, the value of y is -6
So, y-intercept of Line B is -6
The y-intercept of Line A is 2 and the y-intercept of Line B is -6.
Therefore, the y-intercept of Line A is greater than y-intercept of Line B

Answer:
x = 4
which agrees with the third listed answer among the given options
Step-by-step explanation:
We can re-write the logarithmic equation using the properties of logarithms:
Therefore, the arguments of the log functions must also be equal (and we can solve for "x" by noticing that this expression is the perfect square of a binomial:
and for this equation to verify, x must be 4
