Answer:

5

Step-by-step explanation:

First you want to find f(-2)

Then whatever f(-2) equal, you plug into g(x) to find g(f(-2))

So first lets find f(-2)

Looking at the f(x) graph. When -2 is inputted ( x value -2 ) the output is 1

So f(-2) = 1

We then plug in 1 into g(x) to find g(f(-2))

Think of it as 1 replacing f(-2) in g(f(-2)) because f(-2) = 1

So g(f(-2)) = g(1)

We then look at the graph g(x)

when 1 is inputted the output is 5

Therefore g(f(-2)) = 5

Step-by-step explanation:

The required point is at the midpoint of AB

Use the midpoint formula

Given A(4, 3) and B(- 2, 6 ), then

midpoint = [ 0.5(4 - 2), 0.5(3 + 6) ] = (1, 4.5 )

What is the value of x in the diagram?
dalvyx [7]

Answer:

x = 30

Step-by-step explanation:

here 50 is hypotenuse as it is opposite of 90 degree.

x and x + 10 are the two other smaller sides of a right angled triangle respectively.

using pythagoras theorem,

a^2 + b^2 = c^2

x^2 + (x + 10)^2 = 50^2

x^2 + x^2 + 20x + 100 = 2500

2x^2 + 20x + 100 = 2500

2x^2 + 20x + 100 - 2500 = 0

2x^2 + 20x - 2400 = 0

2(x^2 + 10x - 1200) = 0

x^2 + 10x - 1200 = 0

x^2 + (40 - 30) - 1200 = 0

x^2 + 40x - 30x - 1200 = 0

x(x + 40) - 30(x + 40x) = 0

(x + 40)(x - 30) = 0

either x + 40 = 0          OR x - 30 = 0

x = 0 - 40

x = -40

x - 30 = 0

x = 30

x = -40,30

since the length and distance is not measured in negative ur answer will be 30
