Write the equation of a line that is perpendicular to x=5.
Write the equation of a line that is parallel to 4x+3y=1.
Write the equation of a line that is perpendicular to x-5y=2
Write the equation of a line that is perpendicular to x=5.
x=5 is a straight line going through 5 on the x axis. A line perpendicual to this will be any line parallel to the x axis. This would mean y=[Any Number]. Pick what you want for [Any Number}, but I'll choose my lucky number, 6.
y =6
Write the equation of a line that is parallel to 4x+3y=1.
A parallel line have the same slope, so we can start by rewriting the equation in standard form of y=mx + b, where m is the slope and b the y-intercept (the value of y when x=0):
3y = -4x + 1
y = -(3/4)x + (1/3)
The slope is -(3/4), so the new line will also have the nsame slope. Start by putting -(3/4) in the satandard format:
y = -(3/4)x + b
In the absence of any other information, we are free to pick whatever value we want for b, as long as it is not 1. I'll choose . . .
y = -(3/4)x + 6
Write the equation of a line that is perpendicular to x-5y=2
As before, rewrite into standard form:
-5y = -x + 2
y = (1/5)x + 2
A perpendicular equation will have a slope that is the negative inverse of the reference line. The negative inverse of (1/5) is -5. Now we have:
y = -5x + b
Since we aren't given any addition information, we can pick any b we want.
y = -5x + 6
See the attached graph.

Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different
Answer:
subtract 2x from both sides
divide both sides by 3
In y = mx + b form (slope intercept form), the slope will be in the m position and the y int will be in the b position
as u can see, the number in the m position (the slope) = -2/3

Explaning process:
divide 1,593 and 5.
Sal will use 6 dollars for every day and 1593 dollars for each month. For six months, the cost will be 9558.

A straight line PQ passing through points (1,-6) and (6, 14). Determine whether a straight line which passing through (-4,-8) and (-1,7) is parallel to PQ. Explain your answer. [3 markah / marks)
Answer:
line not parallel to PQ
Step-by-step explanation:
Parallel lines have equal slopes
Calculate slopes m of both lines using slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (P (1, - 6) and (x₂, y₂ ) = Q (6, 14 )
[tex]m_{PQ}[/tex] = [tex]\frac{14-(-6)}{6-1}[/tex] = [tex]\frac{14+6}{5}[/tex] = [tex]\frac{20}{5}[/tex] = 4
Repeat with (x₁, y₁ ) = (- 4, - 8 ) and (x₂, y₂ ) = (- 1, 7 )
m = [tex]\frac{7-(-8)}{-1-(-4)}[/tex] = [tex]\frac{7+8}{-1+4}[/tex] = [tex]\frac{15}{3}[/tex] = 5
Since slopes are not equal then lines are not parallel

Answer:
median = 9.5
range = 11
Step-by-step explanation:
mean = (sum of numbers)/(number of numbers)
(18 - x + x - 3 + x + x/2 + 5 + 4x - 10 + 2x - 1)/6 = 9
9 + 7x + x/2 = 54
7x + x/2 = 45
14x + x = 90
15x = 90
x = 6
Now we can write the 6 numbers.
12, 3, 6, 8, 14, 11
We write the numbers is increasing order.
3, 6, 8, 11, 12, 14
The median is the mean of the 2 middle numbers.
median = (8 + 11)/2 = 19/2 = 9.5
The range is the difference between the larges and smallest of the numbers.
range = 14 - 3 = 11

In a shop, the normal price of a coat is £65.
The shop has a sale.
In week 1 of the sale, the price of the coat is reduced by 20%
In week 2 of the sale, the price of the coat is reduced by a further £10.
Maria has £40.
Does Maria have enough money to buy the coat in week 2 of the sale?
You must show how you get your answer.
Answer:
hope this helps plz mark brainliest
Step-by-step explanation:
Hence Maria does not have enugh money to buy the coat in week 2 of the sale
Normal price of a coat : 65
As in week 1 of the sale = 65 - 20/100 x 65
= 65 - 13 = 52
Also in week 2 of the sale the price of the coat is reduced by a futher 10

Given side AB in ΔABC has length x, what is the length of side AC?
A) x B) x 2 C) x 3 Eliminate D) 2x
The length of AC from the given diagram is 14.0cm
Find the diagram attached below;
From the diagram, we need to first find the value of side AB using the SOH CAH TOA identity
Given the following
Opposite = x
Adjacent = 9cm
Angle of depression = 50 degrees
Tan theta = opposite/adjacent
Tan 50 = x/9
x =9tan 50
x = 10.73
Get the hypotenuse using the pythagpras theorem
AC = √AB²+BC²
AC = √10.73²+9²
AC = √196.04
AC = 14.00
Hence the length of AC from the given diagram is 14.0cm

Let f(x) = x*g(h(x)) where g(4) = 2, g'(4) = 3, h(3) = 4, and h'(3) = -2. Find f'(3).
By the product and chain rules,
f'(x) = g(h(x)) + x g'(h(x)) h'(x)
Then
f'(3) = g(h(3)) + 3 g'(h(3)) h'(3)
f'(3) = g(4) + 3 g'(4) (-2)
f'(3) = g(4) - 6 g'(4)
f'(3) = 2 - 6(3)
f'(3) = -16
Is -1.2 greater than 0.8?
Answer:
no
Step-by-step explanation:
a negative value is never greater than a positive one
Answer:
No
Step-by-step explanation:
-1.2 is a negative number which means it is subtracted, but 0.8 is a fraction of 1, while -1.2 is 1.2 less than one. So 0.8 is larger than -1.2
