Answer:

Step-by-step explanation:

1/4 (8 - 4 p) + 2 p = 12

Distribute

2 -p +2p =12

Add like terms

2 +p = 12

Subtract 2 from each side

2+p-2 = 12-2

p = 10

Which polynomial is a perfect square trinomial?

Levart [38]

Answer:

$\large\boxed{16x^2-24x+9=(4x-3)^2}$

Step-by-step explanation:

$\text{Perfect square:}\ (a-b)^2=a^2-2ab+b^2\\=======================\\\\25x^2-20x-16\to\text{NOT. Because is}\ -16=-4^2\\\\9a^2-30a-25\to\text{NOT. Because is}\ -25=-5^2\\\\25b^2-15b+9=(5b)^2-2(5b)\left(\dfrac{3}{2}\right)+3^2\to\text{NOT. Because is}\ b=\dfrac{3}{2}\ \text{and}\ b^2=3^2\\\\16x^2-24x+9=(4x)^2-2(4x)(3)+3^2=(4x-3)^2\ \boxed{YES\ :)}$

On a piece of paper, graph y>x-1. Then determine which answer choice

zepelin [54]

The graph that matches the given equation is y≥x-1 is Graph A.

Option: C.

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

The given equation y≥x-1 is a linear inequality equation.

Graphing Linear Inequalities differs from graphing regular linear equations. That is it has certain rules to be followed to draw the graph.

First, rearrange the equation as y in the left and other terms in the opposite side.
Check for the line: y= , y≤ and y≥ comes with straight line where as y< and y> comes with a dotted line.
Shading: If y> greater than or y≥ greater than or equal is present then the space above the line has to be shaded. If y< less than or y≤ less than or equal is present then the space below the line has to be shaded.

For the given equation y≥x-1,

The line will be solid passing through (0,-1) and (3,2) since it has y≥. Also, the region above the line is shaded.

So the graph A is the graph that matches the equation y≥x-1.
