Given the following functions f(x) and g(x), solve f over g(−4) and select the correct answer below:
oksian1 [2.3K]
X = -4
As g(x) is replaced by g(-4)
plug in -4 for x inside the equation.
g(-4) = (-4) - 1g(-4) = -5
Plug in -4 for x in f(x)f(-4) = 4(-4) - 4f(-4) = -16 - 4f(-4) = -20
Now solve for f(x) over g(x)
remember, f(x) = -20, and g(x) = -5
-20/-5  = 4
4 should be your answer
hope this helpsClick to let others know, how helpful is it

A/4 + 2 = 6 &amp;' -4 = r/20 - 5 can u please help me on these two
statuscvo [17]
A/4 + 2 = 6....subtract 2 from both sides
A/4 = 6 - 2
A/4 = 4...multiply both sides by 4, eliminating the 4 on the left side
A = 4 * 4
A = 16

-4 = r/20....multiply both sides by 20, eliminating the 20 on the right side
-4 * 20 = r
-80 = r

AB is a line of symmetry of this arrow shape. A)Calculate The Perimeter of the shape.
maw [93]

Answer:

A)58cm

B)h=4\sqrt{5}cm

C)125.55square cm

Step-by-step explanation:

AB is a line is symmetry

Total length of left half part=12cm+9cm+3cm+5cm

Total length of left half part=29 cm

Length of left half part=Length of right half part

Therefore, length of right half part=29 cm

A) Perimeter of the shape=29cm+29cm=58cm

B)

Pythagoras theorem

(Hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2

Hypotenuse=12 cm

Base=5+3=8cm

In triangle ADC

Now, using Pythagoras  theorem

(12)^2=8^2+h^2

144=64+h^2

h^2=144-64=80

h=\sqrt{80}=4\sqrt{5}cm

C)

Area of shape=Area of triangle+ area of rectangle

Area of shape=\frac{1}{2}\times b\times h+l\times b

Where l=9cm

breadth=3+3=6cm

h=4\sqt{5}cm

base=2(5)+3(2)=16cm

Area of shape=\frac{1}{2}\times\times 16\times 4\sqrt{5}+9\times 6

Area of shape=125.55 square cm
