By most definitions, if the bases are congruent, it is not a trapezoid, it is a parallelogram.
Answer:
-5
Step-by-step explanation:
Rate of Change also slope
Slope = y-y1/x-x1 = tanα = y/x
15-5/2-4 = 10/-2 =-5
You can reword the two equations as:
-5x-y=15 (Divide original value by 3)
-2x+6y=6
Then use elimination to find x:
-30x-6y=90 (Multiply by 6 to get y values to be same to cancel out)
-2x+6y=6
You're left with:
-32x=96. Which can then be solved to find x which is -3.
Then plug back in
-2x+6y=6
Now to: -2(-3)+6y=6.
Which reduces to 6+6y=6. So y=0.
To graph them, just reword the equations (yes once again) so that y is in front.
y=-5x-15 and y=(1/3)x+1
Answer:
there are 6 dogs
Step-by-step explanation:
x = dogs
x= 2 + 4
x = 6
