Answer: (-2,3)
Step-by-step explanation:
-3x + 4y = 18
6x + 2y= -6 we have to eliminate one of the variables so you will have ot
2(-3x + 4y) = 18(2) multiply the first equation by 2.
-6x + 8y = 36
6x + 2y = -6 now we could eliminate the x terms by adding them and
0 + 10y= 30 remember that is a new equation.
y= 3
Now we know that the y solution is 3 so we will put it into one of the equations and solve for x.
-6x + 8(3)=36
-6x + 24
-24 -24
-6x = 12
x= -2
Answer:
No, not every rectangles are rhombuses
Step-by-step explanation:
Rhombus has all its sides equal, but all its angles are not equal. However, opposite angles are equal.
While rectangle has all its angles equal, but all its sides are not equal. However, opposite sides are equal.
<span>If approximately 2.3 million people die per year in the US, this is equivalent to deaths per minute. Round to the nearest hundredth.
of minutes in a year
365*24*60
of deaths per minute = 2.3x10^6/(365*24*60) = 4.38 deaths/minute</span>
