Well look at this and the angles it points at are the vertex angles and the vertex angles are the vertices

Simplify: -3^2+8÷2×4-|-9|

NNADVOKAT [17]

Follow the order of operations. Evaluate absolute value first.
-3^2+8/2*4-9

Then evaluate exponents
9+8/2*4-9

Then evaluate multiplication and division from left to right
9+4*4-9
9+16-9

Then evaluate addition and subtraction from left to right
25-9
16

Final answer: 16

What is 5/20 as in a percent

Law Incorporation [45]

$\sf \dfrac{5 \div 5}{20 \div 5} = \dfrac{1}{4} \\ \\ 1 \div 4 \\ \\ 0.25 \\ \\ 0.25 * 100 = 25 \%$

Hello, I am currently very stuck with this problem and I am unsure as to how I would solve it.

borishaifa [10]

We have the equation

$20y=x^2-10-15$

Let's complete the square, to do it let's add and subtract 25 on the right side

$\begin{gathered} 20y=x^2-10-15+25-25 \\ \\ 20y=(x-5)^2-15-25_{} \\ \\ 20y=(x-5)^2-40 \\ \\ \end{gathered}$

Now we can have y in function of x

$\begin{gathered} y=\frac{1}{20}(x-5)^2-2 \\ \\ \end{gathered}$

Now we can already identify the vertex because it's in the vertex form:

$y=a(x-h)+k$

Where the vertex is

$(h,k)$

As we can see, h = 5 and k = -2, then the vertex is

$(5,-2)$

Now we can continue and find the focus, the focus is

$\mleft(h,k+\frac{1}{4a}\mright)$

We have a = 1/20, therefore

$\begin{gathered} \mleft(5,-2+5\mright) \\ \\ (5,3) \end{gathered}$

The focus is

$(5,3)$

And the last one, the directrix, it's

$y=k-\frac{1}{4a}$

Then

$\begin{gathered} y=-2-5 \\ \\ y=-7 \end{gathered}$

Hence the correct answer is: vertex (5, -2); focus (5, 3); directrix y = -7

The legs of a scalene triangle are represented by (x + 4), (x + 8), and ( 2x − 3). Which polynomial expression BEST represents t

ivanzaharov [21]

The perimeter of the triangle is: 4x+9

Step-by-step explanation:

Perimeter is the measurement of boundary of any closed figure.

Given

s1 = x+4

s2 = x+8

s3 = 2x-3

So, the perimeter will be the sum of all three sides

$P = s_1+s_2+s_3\\= (x+4) + (x+8) + (2x-3)\\= x+4+x+8+2x-3\\= 4x+9$

Hence,

The perimeter of the triangle is: 4x+9
