Answer:

addition property of equality

Step-by-step explanation:

Given the equation 4(x-5) = -12

Expand

4x - 20 = -12

Add 20 to both sides (addition property of equality)

4x-20+20 = -12+20

4x = 8

x = 8/4

x = 2

Hence the value of x is 2

The justification for step 2 is addition property of equality

Vector v1 is 6.6 units long and points along the negative x axis. vector v2 is 8.5 units long and points at + 55° to the positiv
natita [175]
(a) what are the x and y components of each vector?
 For vector v1:
 
v1 = 6.6 (cos (180) i + sine (180) j)
 v1 = 6.6 (-1i + 0j)
 v1 = -6.6i
 
For vector v2:
 
v2 = 8.5 (cos (55) i + sine (55) j)
 v2 = 8.5 ((0.573576436) i + (0.819152044) j)
 v2 = 4.88 i + 6.96 j
 (b) determine the sum v v 1 2

 The sum of both vectors is given by:
 v1 + v2 = (-6.6i) + (4.88 i + 6.96 j)
 Adding component to component:
 v1 + v2 = (-6.6 + 4.88) i + (6.96) j
 v1 + v2 = (-1.72) i + (6.96) j

What is the domain of the rational function, f of x equals quantity x minus 5 over quantity 2 times x minus 3
liq [111]

Answer:

<u>Domain = R - {3/2}</u>

Step-by-step explanation:

The domain of a rational function consists of all the real numbers x except those for which the denominator is 0

The given function is :

f(x) = \frac{x-5}{2x-3}

We need to find the zeros of the denominator

∴ 2x - 3 = 0    ⇒ add 3 to both sides

∴ 2x = 3          ⇒ divide both side by 2

∴ x = 3/2        

The domain will be all real number except the zeros of the denominator.

So, Domain = R - {3/2}

Also, see the attached figure that represents the given function.
