Answer:
20%
Step-by-step explanation:
7000-5600=1400
1400/7000×100=20
Vertical angles are congruent due to the fact that they intersect. If they did not, they would in fact be parallel. (last section)
Answer: If you want mx + b= y form and you want the y intercept, then the answer would be 2x/7 - 12/7 = y. The y intercept is b, so it is 12/7.
Step-by-step explanation: 2x - 7y = 12
Move -7y to the other side: 2x= 12 + 7y
Subtract 12 to the left side: 2x - 12 = 7y
Then divide 7 into everything: 2x/7 - 12/7 = 7y/7
The 7s in the right side cancel out, so the equation is now: 2x/7 - 12/7 = y
The y intercept is b, which is the second term in the equation, so the
Y Equals : 12/7
I hope this is what you are looking for!
Would it be 4(1)^2+2(2(1)+2)^2=100
It would be: 213500 * 18/100
213500 * 0.18 = $38430
So, option D is your answer.
Hope this helps!
