62 cm. plug in 4 for x. 2(5(4)-2))+2(3(4)+1))= 2(18)+2(13)= 36+26=62. Hope this helps!
Salutations!
Mark got 20% raise for his salary. If this salary was $1800 what is the new salary?
So lets solve this!
Mark got 20% "raise" for his salary. It clearly indicates that it is percentage of increase, so therefore, after solving out all the sum, we would be adding up 1800 to get the total of the new salary.
Lets form this into statements ----
Percentage increase = 20%
Mark's old salary = $1800
Mark's new salary = 20 × 1800/100
Cancel out the zeros to make it more logical ----
20 × 18/1
= 360.
Now, we need to add 1800 and 360 to get Mark's new salary
1800 + 360 = $2160.
Mark's new salary is $2160.
Hope I helped :D
domain is the 1st entry and range is sevond. entry
So to solve problems like these you can work out each equation by substituting the x and y with the coords from the vertex (2,-4) and which ever one is true is the corresponding equation.
Lets try the first one
A) y = 2( x-2)^2-4 this would become
-4 = 2(2-2)^2-4 we solve this and get
-4 = 2(0)-4
-4 = -4
so it seems like A is the correct answer, of course we'd wanna check out the other answers just to be sure.
Lets try one and do C
C) -2 = 2(-4-2)^2+2
-2 = 2(-8)^2+2
-2 = 130
These aren't equal so this can't be our equation
So you can also do one more just to be super sure you have the right answer but I think A is the correct one :)
