What is an equation of the axis of symmetry for the parabola whose equation is y=2x^2-3x+4
krek1111 [17]

Answer:

x = 3/4 or x = 0.75

Step-by-step explanation:

y=2x²-3x+4

y'=4x-3 = 0

x = 3/4 .... answer

or

x = - b/2a    ...y=ax²+bx+c

x = - (-3)/(2*2) = 3/4

What is the y-value in the solution to this system of linear equations?
baherus [9]

Answer:

Option  A.)−4

Step-by-step explanation:

we have

4x+5y=-12 -----> equation A

-2x+3y=-16 -----> equation B

Solve the system of equations by elimination

Multiply the equation B by 2

2*(-2x+3y)=-16*2

-4x+6y=-32 -----> equation C

Adds equation A and equation C

4x+5y=-12

-4x+6y=-32

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

5y+6y=-12-32

11y=-44

y=-4

If f(5) = 3.7 and f(6) = 8.7...<br> f(7) =<br> f(8) =<br> Recursive Function Is
Hitman42 [59]

Answer:

f(7) = 13.7

f(8) = 18.7

Recursive Function Is: f(1) = -16.3; (fn) = f(n - 1) + 5

Step-by-step explanation:

The recursive function of the arithmetic sequence is

f(1) = first term; f(n) = f(n-1) + d, where

  • d is the common difference between each two consecutive terms

∵ f(5) = 3.7 and f(6) = 8.7

∵ d = f(6) - f(5)

∴ d = 8.7 - 3.7

∴ d = 5

∵ f(7) = f(6) + 5

∴ f(7) = 8.7 + 5

∴ f(7) = 13.7

∵ f(8) = f(7) + 5

∴ f(8) = 13.7 + 5

∴ f(8) = 18.7

→ To find f(1) subtract from each term the value of d

∵ f(5) = f(4) + d

∴ f(4) = f(5) - d

∴ f(4) = 3.7 - 5

∴ f(4) = -1.3

∵ f(3) = f(4) - 5

∴ f(3) = -1.3 - 5

∴ f(3) = -6.3

∵ f(2) = f(3) - 5

∴ f(2) = -6.3 - 5

∴ f(2) = -11.3

∵ f(1) = f(2) - 5

∴ f(1) = -11.3 - 5

∴ f(1) = -16.3

∴ Recursive Function Is: f(1) = -16.3; (fn) = f(n - 1) + 5
