We can solve this system of equation by reduction method.
d+e=15
-d+e=-5
-------------------
2e=10 ⇒e=10/2=5
-(d+e=15)
-d+e=-5
-----------------
-2d=-20 ⇒d=-20/-2=10
therefore: d=10; e=5
Answer: d.(10,5)
Answer:
trapezoid one is 336 inches squared
trapezoid two is 9 inches squared
Step-by-step explanation:
The formula for a trapezoid is b1+b2 so the number on the top line = the number on the bottom line, you then multiply your new number by the height which is the number bye the dotted red line.
Hope this helps!
Add the temps up
-24 + (-15) + (-21) + (-32) + (-18) + (-9) + (-14) = -133
now divide by how many numbers there are
-133/7 = -19 <== the mean (average)
I'm going to say 3 1\2. Let me know when you get the answer.
Answer:
Because you did not give the slope, we cannot get the exact equation. However, using m as a substitute for slope, the point-slope form would be y - 7 = m(x + 4)
Step-by-step explanation:
We can find this equation through the use of the base form of point-slope form. Then we can plug in the point where we see fit.
y - y1 = m(x - x1)
y - 7 = m(x + 4)
