The correct answer is c :)
the point is described by two variables: x and y. it is written like that: (x, y). so the first variable in brackets is the x variable. the other is y. so pick every point a-d, put these values into the equation, solve it and check if the values before and after = are the same. if so - you are correct!
look:
c) (1, 5) so x=1, y=5
equation: y=5^x
putting values: 5=5^1 and this is true!

Tell whether each scale reduces enlarges or preserves the size of an actual object
mr_godi [17]

Given:

1 m : 25 cm

8 in : 1 ft

12 in : 1 ft

 

First, we convert each variable given on the right:

 

1 m : 0.25 m (this means that 1 meter is made to represent 25 cm)

8 in : 12 feet (this means that 8 in is made to represent 1 feet)

12 in : 12 in (this means that 12 in is made to represent 1 feet)

 

<span>After converting the variables, we can now know if the ratios are enlargement, reduction or preservation. Therefore:

1 m : 25 cm = Enlarge</span>

<span>8 in : 12 feet = Reduce
12 in = 1 ft = Preserve</span>

If f(x) = x/2-3 and g(x) = 4x2 + x - 4, find (f+ g)(x).
snow_tiger [21]

Answer:

(f+g)(x) = 4 x^2 + (3/2) x - 7

Answer (c) on your list

Step-by-step explanation:

f+g (x) = f(x) + g(x) = x/2 - 3 + 4 x^2 + x - 4

combine the terms in "x" = x/2 + x = (3/2)x

combine the numerical terms: - 3 - 4 = - 7

Then the final expression is:

(f+g)(x) = 4 x^2 + (3/2) x - 7

strojnjashka [21]
If you're asking if they are equal, they're not.

16/28 = 240/420 or 320/560.
