Answer: 17.5

Step-by-step explanation:

x = -5

f(-5) = -x^2+0.5x-5

= -(-5)^2 + 0.5(-5)-5

= 5^2 + (-2.5) - 5

= 25 - 2.5 - 5

= 17.5

Explain how you know if an equation has one solution, infinitely many solutions, or no solution
lubasha [3.4K]
No solution would mean that there is no answer to the equation. It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true. :)

Identify the parameters in y = a*bkx.
Natasha2012 [34]
Convention in algebra is that we use letters such as a, b, c, etc., for parameters and letters such as x, y z, and so on, for variables.

Thus the parameters here are a, b and k.  k is the constant of proportionality.

If cos(x) = 0.5, then what is x?
Anestetic [448]

Answer:

=60 the second option.

Step-by-step explanation:

Given the trigonometric ratio, we can find the value of the angle by simply finding the inverse of the given ratio.

If for example Cos ∅= a, then ∅=Cos⁻¹a

If Cos (x)= 0.5, then x= Cos⁻¹ 0.5

Cos⁻1 0.5=60°

The angle whose sine is 0.5 is ∅=60°
