Answer: b the equation has one solution and the solution is 0

Step-by-step explanation:

first subtract 4x from both sides you should end up with something like this after you subtract 4x from both sides

( 3(2+x)+4x-4x=6+4x-4x)

3(2+x)=6

then divide both sides by three you then sould have something like this after you divide both sides by three

( 3(2+x)/3=6/3)

2+x=2

then subtract 2 from both sides you shoould end up with the answer of

( 2+x-2=2-2)

x=0

What transformations are represented by the following coordinate graphing? (geometry)

Minchanka [31]

Answer:

(a,b) → (a,-b) : Reflection about x axis.

(a,b) → (a, b+5) : Translation of the point by 5 units up.

(a,b) → (b,-a) : Rotation by 90 degree clockwise.

Step-by-step explanation:

Given:

The transformation of points are given as:

(a,b) → (a,-b)

(a,b) → (a, b+5)

(a,b) → (b,-a)

Now, let us consider each transformation one by one.

(1) (a,b) → (a,-b)

Here, the order of the coordinates has not changed. But, the y coordinate of the point has changed. The y coordinate was 'b' and it has changed only its sign but not value. So, it is a transformation related to reflection.

In reflection, only the sign changes. Since, the 'y' coordinate sing is reversed, so, it is a reflection about x axis.

(2) (a,b) → (a, b+5)

Here, the 'y' coordinate of the point has changed. The change is from 'b' to 'b+5'. So, 5 is added to the y coordinate. As per transformation rules, if a positive number 'C' is added to the y coordinate, then the point shifts vertically up by 'C' units. Hence, there is a translation of 5 units up here.

(3) (a,b) → (b,-a)

Here, the 'x' and 'y' coordinates interchange their values and also the new y coordinate has its sign reversed. This happens in rotation.

We know that, (x, y) → (y, –x) is true when there is rotation by 90 degree clockwise.

So, the point (a,b) → (b,-a) is rotated by 90 degree clockwise.

PLz help I will give brainliest!!!!! and extra points

Natalija [7]

Hey there!

The answer to your question is $95.55$

Formulas:

Area of semi-circle = $\frac{1}{2}(\pi r^2)$

Area of rectangle = $lw$

Area of triangle = $\frac{bh}{2}$

Now solve:

semi-circle

$\frac{1}{2}\pi3^2$

$\frac{1}{2}\pi9$

$4.5\pi$

(We will use 3.14 as approx. for pi)

$4.5 * 3.14\\23.55$

rectangle

$10(6)\\60$

triangle

$\frac{4(6)}{2}$

$\frac{24}{2} \\12$

Now add them all together:

$23.55+60+12\\95.55$

Have a terrificly amazing day!

Khalil says that any time two numbers are the same distance from 0, their sum will be zero. Marius disagrees. "Sometimes the sum

Gelneren [198K]

Answer:

Marius is right.

Step-by-step explanation:

So although what Khalil said could be correct, they didn't say it right. It would be any two numbers the same distance from 0 going the opposite ways, which means that if you had 3 on one side, you would have -3 on the other side. BUt since Khalil said it wrong, he's basically saying that you can do 3+3 because they're both the same distance away from 0. or you could do (-3)+(-3)=-6 which would still work because they're the same distance away from 0. So unless you just skipped on that part while typing the question, Marius is correct.

Help plzzzzz hurry

V125BC [204]

Answer:

-9, -5, -4.1, -4

$\\q\leq -4$

Step-by-step explanation:

I think what you're missing here is that there is a negative sign in front of the q. This means that whatever number you put in for q will be multiplied by negative 1. Positive numbers will become negative, and negative numbers will become positive.

If you substitute 9 for q you will get $-9\geq 4$ , which is clearly not true, because -9 is way less than 4.

For writing the equation you divide both sides by -1. When you do this however, you must flip the inequality sign

$-q\geq 4\\q\leq -4$

the > sign turned into <, and the q and 4 switched signs.
