Answer:
12
Step-by-step explanation:
84/7 is 12, so she was going 12 mph
Answer:
The graph of function g is the graph of function f shifted 6 units up
Step-by-step explanation:
If you plug in the values,
. If the 6 was added or subtracted from the x in the exponent, it would shift horizontally (left and right), but adding 6 to f(x) separately moves the graph vertically (up and down). Hope this helps.
ANSWER
The required line is BC
EXPLANATION
We want to find the line that passes through

and has slope

Since the x-value of the given point is zero, the point

is the y-intercept.
From the above graph, the two lines that contains

are line CE and line BC.
Since, the slope

is negative, line BC is the required line because it is sloping backwards.
We can confirm this by using the point,

and

to find the slope and obtain
Answer:
Step-by-step explanation:
<u>Given system:</u>
The solution is the common area shaded by the inequalities.
The lines are parallel because of same slope.
Both lines are solid because of equal sign in both inequalities.
The first inequality has a y-intercept of 1 and shaded area is to the left of the line since the value of y is greater as x increases.
The second inequality has a y-intercept of -2 and shaded area is to the right of the line since the value of y is greater as x increases.
The matching graph is the second picture (or attached below) and there is no solution.
