Answer:
1. y= 3x+7
2.y=1/2 x -1
Step-by-step explanation:
1.
Parallel lines have the same gradient.In the equation given,
y= 3x+5 , the slope is 3
So now, you find the equation of a line passing through point (-1,4) with m=3
m=Δ y/Δx
3= y-4/ x--1
3= y-4 /x+1
3(x+1) = y-4
3x+3 =y-4
3x+3+4=y
⇒⇒ y= 3x+7 is the equation.
2.
Two lines that are perpendicular to each other have the product of their slopes to be -1
Given equation to be y= -2x +8 then, m₁ = -2
Finding m₂ will be;
m₁ *m₂ = -1
-2 * m₂ = -1
-2 m₂ = -1
m₂ = -1/-2 = 1/2
So writing the equation of the perpendicular line with m₂ =1/2 , point (-4,-3)
will be;
m=Δy/Δx
1/2=y--3/x--4
1/2 = y+3/x+4
x+4 = 2( y+3)
x+4 = 2(y+3)
x+4 =2y+6
x+4-6=2y
x-2=2y
x/2 -2/2=y
y=1/2 x -1 is the equation.

Answer:
let the hotel charge before tax for second hotel be x
then the hotel charge before tax for first hotel = x+1500
tax of first hotel = 7.5% * (x+1500) = (7.5x+11250)/100
tax from second hotel= 7% of x = 7x/100
total tax = 547.50
7x/100 + (7.5x+11250)/100 =547.50
14.5x = 54750-11250
14.5x= 43500
x= 3000
hotel charge in first city = 4500
in second city =3000
Step-by-step explanation:
The domain and the range of the function are given as follows:
b. Yes; domain: all re.al numbers; range: y greater-than-or-equal-to 0.
<h3>What are the domain and the range of a function?</h3>
- The domain of a function is the set that contains all the values of the input.
- The range of a function is the set that contains all the values of the output.
Since each input is related to only one output values, the graph is a function. It is defined for all values of x, assuming only non-negative values, hence the correct option is:
b. Yes; domain: all re.al numbers; range: y greater-than-or-equal-to 0.
