Triangle $ABC$ with vertices of $A(6,2)$, $B(2,5)$, and $C(2,2)$ is reflected over the x-axis to triangle $A'B'C'$. This triangle is reflected over the y-axis to triangle $A''B''C''$. What are the coordinates of point $C''$

Answers

Answer:

C''(-2, -2)

Step-by-step explanation:

Reflection over the x-axis negates the y-coordinate. Reflection over the y-axis negates the x-coordinate. Negating both coordinates of C(2, 2) makes it ...

Solve for x: log6x-log2=1

Answers

$log6x-log2=1;\ D:6x > 0\to x > 0\to x\in\mathbb{R^+}\n\nlog6x-log2=1\n\nlog\left(6x:2\right)=log10^1\n\n3x=10\ /:3\n\nx=(10)/(3)\n\nx=3(1)/(3)\in D$

$a > 0\ \wedge\ b > 0\ \wedge\ c > 0\ \wedge\ d\in\mathbb{R}\n\nlog_ab-log_ac=log_a(b:c)\n\nlog_ab=d\iff\ a^d=b\ \ (log_ab=log_aa^d)$

Log(6x/2)=1
Log(3x)=1
This is the same as saying 10^1=3x
10=3x
x=10/3 or 3 and 1/3

What is speed?

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance traveled by time. The unit of speed in miles per hour.

Given that Amanda drove to the mountains last weekend. there was heavy traffic on the way there, and the trip took 7 hours. when Amanda drove home, there was no traffic and the trip only took 5 hours. if her average rate was 18 miles per hour faster on the trip home.

The distance will be calculated as,

Distance = S x 7

The other distance is,

Distance = 5 ( S + 18 )

7S = 5S + 90

S = 45 miles

Distance = 45 x 7

Distance = 315 miles

90 miles away since you multiply 18 times 5 would equal 90 miles away.
