Answer:

(1,5) (2,3) (-2,-3)

Step-by-step explanation:

When we rotate a figure of 90 degrees counterclockwise, each point of the given figure has to be changed from (x,y) to (-y,x) and graph the rotated figure.

What are the solutions of the quadratic equation? 4x^2+34x+60=0

Answer:

Option 3) -6,-5/2

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$4x^{2} +34x+60=0$

$a=4\\b=34\\c=60$

substitute in the formula

$x=\frac{-34(+/-)\sqrt{34^{2}-4(4)(60)}} {2(4)}$

$x=\frac{-34(+/-)\sqrt{196}} {8}$

$x=\frac{-34(+/-)14} {8}$

$x_1=\frac{-34(+)14} {8}=-\frac{20}{8}=-\frac{5}{2}$

$x_2=\frac{-34(-)14} {8}=-6$

Is this linear, exponential, or quadratic?

Lady_Fox [76]

Linear. Each increase of 1 in x means a decrease of 3 in y, so it has a consistent slope of -3

?????????????????????????????????????????????????????

Harrizon [31]

Answer:

9 yd

Step-by-step explanation:

A cube consists of 6 square faces.

Divide the surface area by 6 for the area of one face

486 ÷ 6 = 81 yd²

The area of a square is

A = s² ( s is the side length )

Here A = 81, then

s² = 81 ( take the square root of both sides )

s = $\sqrt{81}$ = 9

Thus side length is 9 yd
