The area of a triangle is: 1/2bh
The answer will be: Y = -2/5x - 4
Slope intercept form: y= Mx+b
You find the slope (M) using: rise/run formula
You find (b) by looking at the y-intercept
Answer:
21
Step-by-step explanation:
The first thing we do is multiply -3 by -9 to get 27. (Two negatives multiplied cancels each other out). Now we solve for -1+27-5. The resulting answer is 21.
Answer: x = 1
Step-by-step explanation:
substitute 1 for x
1/2(10(1)+6) = -2(1)+10
1/2(10+6) = -2+10
5+3 = -2+10
8=8
