Answer:(-3,-8),(-6,4),(1,-1)
Step-by-step explanation:
Given
Vertices of the triangle are
![P(-3,8), Q(-6,-4),R(1,1)](https://tex.z-dn.net/?f=P%28-3%2C8%29%2C%20Q%28-6%2C-4%29%2CR%281%2C1%29)
Coordinates (a,b) when reflected about x-axis is given as (a,-b) i.e. Y coordinate changes its sign
![\therefore P\rightarrow P'(-3,-8)\\\Rightarrow Q\rightarrow Q'(-6,4)\\\Rightarrow R\rightarrow R'(1,-1)](https://tex.z-dn.net/?f=%5Ctherefore%20P%5Crightarrow%20P%27%28-3%2C-8%29%5C%5C%5CRightarrow%20Q%5Crightarrow%20Q%27%28-6%2C4%29%5C%5C%5CRightarrow%20R%5Crightarrow%20R%27%281%2C-1%29)
Answer:
440
Step-by-step explanation:
1.5 hours he 90 minutes
660/ 90=7.333
7.333*60 (which is how many minutes in an hour = 440 miles
Answer:
pencils amount = 9 pens amount= 9
Step-by-step explanation:
We start this problem forming two linear equations system.
3*X+7*Y=90
Where X is the amount of pencils and Y is the amount of pens
The second equation is given by the statement, the amount of pencils is equal to the amount of pens, so the second equation is:
X=Y
Merging both equations we have:
3*X+7*X=90
Solving for X we have:
10*X=90
X=9
X=Y=9
