Answer:

11x - 10

Step-by-step explanation:

because there is a plus sign between the brackets, we just assume there are no brackets at all........so it will be:

9x - 2 + 2x - 8,,,,,,,,,bring the like terms together

9x + 2x - 2 - 8 = 11x -10.

the answer has a minus sign because when working out two negative numbers, we add them but still maintain the negative sign.

NOTE: If the sign between the brackets was a minus , the sign in the second expression would have changed from -8 to +8

Answer:

For the first one use the formula

y=x*2

For the second use

y=x*4

The third is

y=x*15

The fourth is

y=x*16

Step-by-step explanation:

To find the value of the y units, u have to multiply any x unit with the first y unit given but not 0

idk if it makes sense but i tried

Select a setting so that each given point will lie within the viewing window.

NemiM [27]

Answer:

The given points are

$(-13,3)\\(0,0)\\(-2,-7)$

The setting would have a interval or 2 units above and below the minimum and maximum of each coordinate.

The given maxium horizontal coordinate is 0.

The given minimum horizontal coordinate is -13.

The given maximum vertical coordinate is 3.

The given minimum vertical coordinate is -7.

Now, we extend each maximum and minimum value by 2 units to create the setting.

So, the setting is

$x_{min}=-15\\x_{max}=2\\ y_{min}=-9\\y_{max}=5$

With a scale of 2 units.

If f(x)=x+4 and g(x)=x^2-1, what is g(f(x))?

pickupchik [31]

g(f(x)) means plug in f(x) for every "x" in g(x).

g(f(x))=(x+4)^2-1=x^2+8x+16-1=x^2+8x+15

answer: x^2+8x+15
