Answer:

The answer is A.

Step-by-step explanation:

Realize that the red graph is simply the blue graph shifted downwards. Hence, we simply need to subtract the units shifted from the original equation.

We see that the red graph shifted downwards by 3 units. Thus, we simply need to subtract three from the original equation.

Thus we have:

$(4-x^2)-3$

Which gives:

$1-x^2$

Here, 1 is also the y-intercept, verifying our answer.

Which statements are true regarding undefinable terms in geometry? Select TWO options

lakkis [162]

Answer:

3) A line has one dimension, length. (True)

5) A plane consists of an infinite set of lines. (True)

Step-by-step explanation:

There are 3 undefined terms in geometry.

a) point

b) line

c) plane

From the given options lets check which statements are true and which are false:

1) A point in the form (x, y) has two dimensions (False)

A point has no dimension

2) A plane has a definite beginning and end. (False)

A plane extends infinitely far and has indefinite beginning and end.

3) A line has one dimension, length. (True)

4) A point consists of an infinite set of lines (False)

A line consists of infinite set of points.

5) A plane consists of an infinite set of lines. (True)....

Which of these equations have no solution? Check all that apply. 2(x + 2) + 2 = 2(x + 3) + 1 2x + 3(x + 5) = 5(x – 3) 4(x + 3) =

o-na [289]

Answer:

2(x + 2) + 2 = 2(x + 3) + 1
2x + 3(x + 5) = 5(x – 3)
5(x + 4) – x = 4(x + 5) – 1

Step-by-step explanation:

It can be easier to see the answer if you subtract the right side of the equation from both sides, then simplify.

1. 2(x + 2) + 2 = 2(x + 3) + 1

2(x + 2) + 2 - (2(x + 3) + 1) = 0

2x +4 +2 -2x -6 -1 = 0

-1 = 0 . . . . no solution

2. 2x + 3(x + 5) = 5(x – 3)

2x + 3(x + 5) - 5(x – 3) = 0

2x +3x +15 -5x +15 = 0

30 = 0 . . . . no solution

3. 4(x + 3) = x + 12

4(x + 3) - (x + 12) = 0

4x +12 -x -12 = 0

3x = 0 . . . . one solution, x=0

4. 4 – (2x + 5) = (–4x – 2)

4 – (2x + 5) - (–4x – 2) = 0

4 -2x -5 +4x +2 = 0

2x +1 = 0 . . . . one solution, x=-1/2

5. 5(x + 4) – x = 4(x + 5) – 1

5(x + 4) – x - (4(x + 5) – 1) = 0

5x +20 -x -4x -20 +1 = 0

1 = 0 . . . . no solution

Not exactly. there are still 40 percent of the employees that are not top performers. for all you know those 40 percent could make up the majority of the employees in the training program<span />

Miyoko's goal is to earn more than \$950$950dollar sign, 950 this week. She earns \$250$250dollar sign, 250 for every day she wo

GrogVix [38]

$250 c+ $ 180 g > $ 950

<u>Step-by-step explanation:</u>

As a cryptographer (c), Miyoko earns per day = $ 250

As a geologist (g) , Miyoko earns per day = $ 180

So the equation comes to be $250 c+ $ 180 g = $ 950

The equation can be rewritten to find c as, (950-180 g) / 250

The equation can be rewritten to find g as, (950 - 250 c) / 180

Plugin different values of c and g in the above 2 equations, we can find that ,

To achieve the goal, Miyoko requires to be a geologist for 3 days and crpytographist for 2 days.
