Answer: Second graph is the correct option.

Step-by-step explanation:

Since we have given that

$y=-2(2)x+2\\\\y=-4x+2$

We will find the coordinate on y - axis first,

for coordinates on y-axis then x must be equal to 0.

so, put x=0,

$y=-4(0)+2\\\\y=0+2\\\\y=2$

So, according to this, Second graph has satisfied it.

Hence, Second graph is the correct option.

This is the table of values of a function. Write the output when the input is n.

denis23 [38]

Answer:

n-2

Step-by-step explanation:

1. Find what has been done to the input value to give the output value. Here, we can see that each input value is two more than each output value, so two has been subtracted from each input value to give the output. This means that the rule for this function is: <em>take the input value and subtract two.</em>

2. Express this in terms of n. We can then express this in terms of n (using n to show the rule that we have found). Since n is the input value we have, to find the output when the input is n, we subtract two from n. This gives us our answer of n-2.

Which graph represents the piecewise-defined function f(x) = StartLayout enlarged left-brace 1st Row 1st column negative 1.5 x +

PilotLPTM [1.2K]

Answer:

Option A or first option

Step-by-step explanation:

The function is

$f(x) = \left \{ {{-1.5x + 3.5, x$

Correct description is the first option with the exception of point (2,0), it should read (2, 0.5)

On a coordinate plane, a piecewise function has 2 lines. The first line has an open circle at (2, 0) and then goes up through (1, 2) with an arrow instead of an endpoint. The second line has a closed circle at (2, 6) and goes up through (3, 7) with an arrow instead of an endpoint.

In Game 1, Emerson struck out 30 times in 90 times at-bat. In Game 2, he struck out 40 times in 120 times at-bat. In Game 3, Eme

Anna71 [15]

Answer:

32% of the times at-bat.

Step-by-step explanation:

Since in Game 1, Emerson struck out 30 times in 90 times at bat; in Game 2, he struck out 40 times in 120 times at bat; and in Game 3, Emerson struck out 42 times in 140 times at bat; To determine what percentage of times at bat did Emerson actually hit the ball, the following calculation must be performed:

$\frac{(30+40+42)}{(90+120+140)}=x$

$\frac{112}{350} =x$

$0.32=x$

Therefore he actually hit the ball 32% of the time.
