Answer:

\sf D.\:\sf (f-g)(x)= |17x+1|-6

Step-by-step explanation:

Hello there!

Let's solve this Linear functions

\sf f(x)=|7x+1|-8

\sf g(x)=-2

\sf |7x+1|-8-(-2)

\sf |7x+1|-8+2

\sf |17x+1|-6

Answer:

The answer is D

Step-by-step explanation:

when \: fx =  |7x + 1|  - 8 \\ while \: y \\ gx =  - 2 \\ therefore \: find(fx - gx) \\  (|7x - 1|  - 8) - ( - 2) \\  |7x - 1|  - 8 + 2 \\   |7x - 1|  - 6

Answer:

The perimeter of triangle is 19.8 units

Step-by-step explanation:

we know that

The perimeter of triangle ABC is

P=AB+BC+AC

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

step 1

Find the distance AB

we have

A(-2,3),B(3,0)

substitute in the formula

d=\sqrt{(0-3)^{2}+(3+2)^{2}}

d=\sqrt{(-3)^{2}+(5)^{2}}

d_A_B=\sqrt{34}\ units

step 2

Find the distance BC

we have

B(3,0),C (-4,-3)

substitute in the formula

d=\sqrt{(-3-0)^{2}+(-4-3)^{2}}

d=\sqrt{(-3)^{2}+(-7)^{2}}

d_B_C=\sqrt{58}\ units

step 3

Find the distance AC

we have

A(-2,3),C (-4,-3)

substitute in the formula

d=\sqrt{(-3-3)^{2}+(-4+2)^{2}}

d=\sqrt{(-6)^{2}+(-2)^{2}}

d_A_C=\sqrt{40}\ units

step 4

Find the perimeter

P=AB+BC+AC

substitute the values

P=\sqrt{34}+\sqrt{58}+\sqrt{40}

P=19.8\ units
