Consider the function f(x) = 2^x
Sonja [21]

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, g(x) = 2^{x} + 6. 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.

Which lines have slope -4/5 and contains point (0,1)?
miv72 [106K]
ANSWER

The required line is BC


EXPLANATION

We want to find the line that passes through
(0,1)

and has slope
m =  -  \frac{4}{5}


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

(0,1)

is the y-intercept.


From the above graph, the two lines that contains
(0,1)

are line CE and line BC.

Since, the slope

m =  -  \frac{4}{5}
is negative, line BC is the required line because it is sloping backwards.


We can confirm this by using the point,


B(-5,5)

and

C(0,1)


to find the slope and obtain


m =  \frac{5 - 1}{ - 5 - 0}  =   - \frac{4}{5}

Which graph shows the solution to the system of linear inequalities?
tangare [24]

Answer:

  • See below

Step-by-step explanation:

<u>Given system:</u>

  • y ≥ 2x + 1
  • y ≤ 2x – 2

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.
