Answer:

C (x ≥ -6)

Step-by-step explanation:

<u>Algebraic:</u>

The domain of $\sqrt{x}$ is $x\geq 0$ . When transformed 6 units to the left, it becomes $x\geq -6$

<u>Graphically:</u>

As shown in the attached graph, $x\geq -6$ .

How do you use inverse operations to find out. x/-7 +6 = 3

Zigmanuir [339]

First you would subtract 6 from both sides.
x/-7 = -3

then you would multiply both sides by -7
x = 21

All I need is the answer and that’s all you have to give me thank you

Misha Larkins [42]

Answer:

Step-by-step explanation:

Once you plot this out, you can see that it is a parallelegram with a base of 3 and a height of three. The base is (-3,-2) to (0,-2) and the height extends to a y value of 1. You can also use triangles for this problem, but I would not suggest to do so because you can solve it a lot quicker this way.

Snowcat [4.5K]

Answer:

56 regular 37 tropical Maximum profit $204.75

Step-by-step explanation:

Constraints are:

r ≥ 0

t ≥ 0

2r+ 3t ≤ 125

2r + 1t ≤ 150

I will multiply the second by -3 to cancel t variable and see what is the maximum amount for the regular

2r + 3t ≤ 225

-6r - 3t ≤ -450

ADD BOTH

-4r ≤ -225

r≤ 56.5

Since we need to pick whole bottles ,not a fraction of a bottle we need ro round down.It should be less than 65.5.So we need 56 bottles of regular

2*56 +3t ≤ 225

112+3t ≤ 225

3t ≤ 113

t≤ 37.6666

37 bottles of tropical

2*56 + 3*37 = 112+111 =223 223<225

2*56 +37 = 112 +37 =149 149<150

$2.5*56 = $140

$1.75*37 = $64.65

Total profit $204.75

Yesterday, teddy played a game repeatedly on his computer and won exactly 85% of the games he played. today, teddy played the sa

Eduardwww [97]

The equation we use here is:
$(0.85)x +(1.00)y = (0.94)(x + y)$
x is for the number of games he played on first day, y is the games on second day. The coefficients are the decimal form of percentages.

Simplify:
$0.85x + y = 0.94x + 0.94y \\ \\ 0.06y = 0.09x \\ \\ \frac{6y}{100} = \frac{9x}{100} \\ \\ 6y = 9x \\ \\ 2y = 3x$

To find x we need to use the ratio. We have 85/100 as the first day's ratio and because the games needs to be whole, we can simplify this as 17/20. So in first day, he played at least 20 games and won 17 of them.

When we plug the 20 into the equation as x:
$2y = 3 \times 20 \\ \\ 2y = 60 \\ \\ y = 30$
So he needs to play at least 30 games in order to get his score to 94%.
