Break it up into 2 triangles. base is 4.5, hypotenuse is 9
4.5^2+b^2=8120.25+b^2=81b^2=60.75

Answer:

Step-by-step explanation:

6)Let the number be x

Product of a number and -4 = x * -4 = -4x

Product of a number and -4 increase by 3 : -4x + 3

-4x +3 = 9

Subtract 3 from both sides

-4x + 3 - 3 = 9 - 3

-4x = 6

Divide both sides by (-4)

-4x/-4 = 6/-4

x = -3/2

x = -1 1/2

7)Let the number be x

$\frac{x}{6}-9=11\\\\$

Add 9 to both sides

$\frac{x}{6}-9+9=11+9\\\\\frac{x}{6}=20\\$

Multiply both sides with 6

$\frac{x}{6}*6=20*6\\\\$

x = 120

Determine the equatiln of the graph and select the correct answer below. <br><br>

olga_2 [115]

Answer:

Step-by-step explanation:

okay, this is actually pretty easy because it just works with simple translations.

(x+a)^2 + b

if a is positive, the graph shifts left

if a is negative, the graph shifts right

if b is positive, the graph shifts up

if b is negative, the graph shifts down

so since the quadratic, is starts at the origin and is shift 3 to the left, and 2 up:

the equation is

(x+3)^2 + 2

Would it be possible for quadratic to have more than one factored form? Why or why not.
