Answer:

5, -1

Step-by-step explanation:

set the given equation equal to 0.

add 9 to both sides

take the square root of both sides and remove the exponent on left side.

x-2 = +3

x-2= -3

solve for x (for each equation)

x= 5, x= -1

The graphs of two linear equations ax + by = c and bx - ay = c, where a, b, c are all not equal to zero.

marin [14]

Let us find the slopes of the two lines

ax+by=c, slope m1 = -a/b

bx-ay=c, slope m2 = b/a

m1*m2 = (-a/b)(b/a) = -1

Therefore the two lines are perpendicular so the answer is D

A game of chance has a spinner with five equal-sized sections, The results of 625 spins are shown below. For which color is the

andrew-mc [135]

The color that has the greatest difference between the theoretical and experimental probability is yellow.

<h3>Which color has the greatest difference?
</h3>

Theoretical probability of each color = number of color in each section / total number of sections

1/5 = 0.2

Experimental probability is based on the result of an experiment that has been carried out multiples times

Experimental probability

Experimental probability of choosing orange = 118 / 625 = 0.19

Difference = 0.2 - 0.19 = 0.01

Experimental probability of choosing purple = 137 / 625 = 0.22

Difference 0.22 - 0.2 = 0.02

Experimental probability of choosing brown = 122 / 625 = 0.20

0.2 - 0.2 = 0

Experimental probability of choosing yellow = 106 / 625 = 0.17

0.20 - 0.1696 = 0.0304

Experimental probability of choosing green = 142 / 625 = 0.23

0.2272 - 0.20 = 0.0272

the time t required to drive a certain distance varies inversely with the speed, r. if it takes 4 hours to drive the distance at

valina [46]

Hello,

Answer A

d :the distance in miles
t: the time in hours
v: the speed in miles/hours (vistesse)

d=v*t
==>d=40*4=160(mi)

d=55*x=160==>x=160/55=2.909090... (mi/(mi/h)=h)≈2.91(hours)
