Oliga [24]2 years ago
8 0

Answer: 14,575

Step-by-step explanation:

85(2) 0.4x = 6000      Multiply 85 times 2

170 + 0.4x = 6000      Subtract 170 from both sides

         0.4x = 5830       Divide 5830 by 0.4

             x = 14,575

A function f defined by f(x) = x² + px + q is such that f(3) = 6 and f¹(3) = 0. Find the value of q.
CaHeK987 [17]

Answer:

q = 15

Step-by-step explanation:

Given

f(x) = x² + px + q , then

f(3) = 3² + 3p + q = 6 , that is

9 + 3p + q = 6 ( subtract 9 from both sides )

3p + q = - 3 → (1)

---------------------------------------

f'(x) = 2x + p , then

f'(3) = 2(3) + p = 0, that is

6 + p = 0 ( subtract 6 from both sides )

p = - 6

Substitute p = - 6 into (1)

3(- 6) + q = - 3

- 18 + q = - 3 ( add 18 to both sides )

q = 15

What is the value of 6x-3x +7 if x=9?
Lynna [10]

6x - 3x + 7 \\ 3x + 7 \\ 3(9) + 7 \\ 27 + 7 \\  = 34
Combine like terms and "plug in" x into the equation to eventually get 34 after some addition

If 2a-b:2a+b=1:2find the value of a:b​
weqwewe [10]

Answer & Step-by-step explanation:

2a - b : 2a + b = 1 : 2

2a - b = 1

-                         Elimination

2a + b = 2

-b - (b) = -1

-2b = -1

b = 0.5

---------------------------------------------------------------------------------

2a + b = 2           Substitution

2a + 0.5 = 2

2a = 1.5

a = 0.75

--------------------------------------------------------------------------------------

a:b

0.75 : 0.5

or

3/4 : 1/2

Hope this helps!!!
