Answer:

P’(-5,2)

J’(0,3)

M’(1,2)

Y’(-4,0)

Step-by-step explanation:

when we rotate 90 degrees clockwise, we have that;

(x,y) becomes (-y,x)

Let us get the coordinates before rotation

P (2,5)

J( 3,0)

M ( 2,-1)

Y (0,4)

After the rotation, we have;

P’(-5,2)

J’(0,3)

M’(1,2)

Y’(-4,0)

Given that x is a nonnegative number, a student conjectured that x + 3 < x2.
nadya68 [22]

Answer:

C (x = 2)

Step-by-step explanation:

Since x is a non-negative number, A and B are eliminated.

This leaves C and D.

C: x = 2,

2 + 3 < 2^2

5 < 4 is false.

So C would be a counterexample.

Hope this helps!

Answer:

\textbf{Hello!}

\Longrightarrow2^2+2z=0

\Longrightarrow x_{1,\:2}=\frac{-2\pm \sqrt{2^2-4\cdot \:1\cdot \:0}}{2\cdot \:1}

\Longrightarrow \sqrt{2^2-4\cdot \:1\cdot \:0}

\Longrightarrow =\sqrt{2^2-0}

\Longrightarrow =\sqrt{2^2}

\Longrightarrow=2

\Longrightarrow x_{1,\:2}=\frac{-2\pm \:2}{2\cdot \:1}

\Longrightarrow x_1=\frac{-2+2}{2\cdot \:1},\:x_2=\frac{-2-2}{2\cdot \:1}

\Longrightarrow\frac{-2+2}{2\cdot \:1}

\Longrightarrow =\frac{0}{2\cdot \:1}

\Longrightarrow =\frac{0}{2}

=0

\Longrightarrow\frac{-2-2}{2\cdot \:1}

\Longrightarrow =\frac{-4}{2\cdot \:1}

\Longrightarrow =\frac{-4}{2}

\Longrightarrow =-\frac{4}{2}

=-2

x=0,\:x=-2\Longleftarrow

A bookstore had 60 copies of a magazine. Yesterday, it sold 2/3 of them. Today, it sold 4/5 of what remained. How many copies do
laiz [17]

Answer:

4 copies

Step-by-step explanation:

After yesterday's sales, 1/3 of the original supply remained. After today's sales, 1/5 of that value remain. So the remaining number is ...

60·(1/3)(1/5) = 60/15 = 4

I barely just learned this and our teacher just told us the shapes and it’s rule but never explain on finding the angles and wan
Alexus [3.1K]

Answer:

as i see from the picture, this lecture mainly taught you relationship of the angles in a specific condition

such as

corresponding angles, AB//CD ,

alternate angles, AB//CD ,

interior angles, AB//CD




In my figure, a+b is always equal to 180degree if the X line is straight

a+b=180


imagine there is Y line which is parallel to the X line

c+d=180


a=c, b=d because y line and x line is parallel (corresponding angles,X//Y)

then b+a=180, substitute c as a, b+c=180(interior angles, X//Y)
