PEMDAS,

P = parenthesis
E = exponent
M = multiplication
A = addition
S = subtraction

4 - 16/4 + 4²

P = not available
E = 4² = 16
M = not available
D = -16/4 = - 4
A = +4

= 16 - 4 + 4 = 16

4 - 16 ÷ 4 + 4²

If you remember PEMDAS, then you know that the first thing you'll do here is the exponent.

4 - 16 ÷ 4 + 16

Next is division.
4 - 4 + 16

Now work out the rest from left to right.
0 + 16
16

The answer is 16.

Y=-8(x+3)(x-2) in standard form

Sliva [168]

Answer:

$\large\boxed{y=-8x^2-8x+48}$

Step-by-step explanation:

The standard form of an equation of a parabola:

$y=ax^2+bx+c$

We have

$y=-8(x+3)(x-2)$ use distributive property: a(b + c) = ab + ac

$y=\bigg((-8)(x)+(-8)(3)\bigg)(x-2)$

$y=(-8x-24)(x-2)$ use FOIL: (a + b)(c + d) = ac+ ad + bc + bd

$y=(-8x)(x)+(-8x)(-2)+(-24)(x)+(-24)(-2)$

$y=-8x^2+16x-24x+48$ combine like terms

$y=-8x^2+(16x-24x)+48\\\\y=-8x^2-8x+48$

Solve the equation for x, where x is a real number (5 points): -11x^2 + 5x - 3 = 0

fenix001 [56]

To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
                   x = [ -b ± √(b^2 - 4ac) ] / (2a)
                   x = [ -5 ± √((5)^2 - 4(-11)(-3)) ] / ( 2(-11) )
                   x = [-5 ± √(25 - (132) ) ] / ( -22 )
                   x = [-5 ± √(-107) ] / ( -22)
Since we conclude that √-107 is nonreal, the answer to this question is that there are no real solutions.
