16x - 10x + 9*99 - 30 = 6x + 861
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
9 degrees
y=x2-10x+30=(x-5)2-25+30=(x-5)2+5
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
16x - 10x + 9*99 - 30 = 6x + 861
Simplifying we get 6x + 9 = 69 so x = 10
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
9 degrees
y=x2-10x+30=(x-5)2-25+30=(x-5)2+5
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
An equals sign seems to be missing. If it is -10x=6y-30 then the slope is -5/3. If it is -10x+6y-30=0 then it is 5/3.
4x+6x=30 is the same as: 10x=30 so we divide by 10 and get: x=3 (I do not see how this relates to calculus, but O.K.)
Depends on the value of x if x is 1 then 10x + 20 = 30 if x is 2 then 10x + 20 = 40 if x is 3 then 10x + 20 = 50 if x is 4 then 10x + 20 = 60 if x is 5 then 10x + 20 = 70 if x is 10 then 10x + 20 = 120 And so on
It will be: 6x2 +8x -15
X2 + 10X - 13 = 17 add 13 to each side X2 + 10X = 30 halve the linear coefficient ( 10 ), square it and add it to both sides X2 + 10X + 25 = 30 + 25 factor on the left and gather terms on the right (X + 5)2 = 55 (X + 5)2 - 55 = 0 ---------------------------vertex form, (- 5, - 55 ), is the vertex -------------------------------------------[-------------------------------]
7x+6 = -3x-24 7x+3x = -24-6 10x = -30 x = -3
