Answer:

- 77

Step-by-step explanation:

To evaluate, substitute x = 4 into g(x) then substitute the value obtained into f(x).

g(4) = 4² + 3 = 16 + 3 = 19

f(19) = (- 4 × 19) - 1 = - 76 - 1 = - 77

Which of the following stanements shows the inverse property of addition?
Nikitich [7]

Answer:

0\cdot \:y+\left(-0\cdot \:y\right)=0  the  statement shows the inverse property of addition as the sum of a number and its inverse is zero.

Step-by-step explanation:

As we know that Inverse Property of Addition states if you add any number to its opposite, the result will be zero.

For example, 13 + (-13) = 0 shows that -13 is the additive inverse of 13.

In other words, the sum of a number and its inverse is zero.

Now checking from the available options,

0y+\left(-0y\right)

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a

=0\cdot \:y-0\cdot \:y

\mathrm{Add\:similar\:elements:}\:0\cdot \:y-0\cdot \:y=0

=0

Thus,

0\cdot \:y+\left(-0\cdot \:y\right)=0

Therefore, 0\cdot \:y+\left(-0\cdot \:y\right)=0  the  statement shows the inverse property of addition as the sum of a number and its inverse is zero.

I have the picture attached
Lisa [10]

Answer:

y = 2/3x + 4

Step-by-step explanation:

First, we look at where the equation intersects the y axis. It intersects at y = 4, which means that in the end of the equation there must be a "+4", so we can rule out the first two.

Second, we look at the slope of the line. Slope is defined as rise over run. As you can see in the graph, the line moves up 2 units while moving right 3 units. That means the coefficient of x (which is the slope) will be 2/3, which means the answer is y = 2/3x + 4.
