The answer is vertex is (5/2, 27/2).
Find x= -b/2a where a=-2, b=10 then plug x value back into function to solve for y value of vertex (x,y).
Since the slope is -2 we know that m=-2. Now use the standard form of y=mx+b and plug in the coordinates (-8,2). We know y=2, x=-8, and m=-2. Therefore we get 2=-2(-8)+b. Now solve for b and you get -14. Therefore, the equation is y=-2x-14.
Hope this helped!
Answer: 11.33
Step-by-step explanation: First you must multiply 42 x 500, which gets you 21,000. Then you divide 238,000 by 21,000 to get 11.33
It’s 4 because it’s a positive 22 and the 18 is negative so you do a positive 22 plus a negative 18 and you get 4 as your answer
Answer:
option 1
Step-by-step explanation:
÷ 
• leave the first fraction
• change division to multiplication
• turn the second fraction 'upside down'
= × 
( cancel 5 and 10 by 5 )
= 
× 
=
