Answer:
y = 2x + 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - [tex]\frac{1}{2}[/tex] x + 7 ← is in slope- intercept form
with slope m = - [tex]\frac{1}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2 , thus
y = 2x + c ← is the partial equation
To find c substitute (- 2, 6) into the partial equation
6 = - 4 + c ⇒ c = 6 + 4 = 10
y = 2x + 10 ← equation of perpendicular line

What percent of $18 is $6?
Answers
33.333% (with the 3 repeating)
1/3 of 18 is 6, so 33.333% (with the 3 repeating) of 18 would be 6.
Answer:
33.333% (its a repeating 3)
Step-by-step explanation:
$6 is 33.33% of 18.
I got this number by dividing 6 by 18, which gave me 0.33333333333.
I then converted 0.33333333333 to a percentage, rounded, and got 33.33%.

hope i helped!! :)
( if it is right, pls mark brainliest!!)
Answer:
25
Step-by-step explanation:
let x represent the first consecutive number.
let x+1 represent the second consecutive number.
let x+2 represent the third consecutive number.
x + x+1 + x+2 = 72
3x + 3 = 72
3x = 72 - 3
3x = 69
3x/3 = 69/3
x= 23
first number= x = 23
second number = x+1
= 23+1
=24
third number= x+2
=23+2
=25
the largest of these numbers is 25

Answer:
C) 18
Step-by-step explanation:
All you have to do is solve the equation.
2.25x + 5 = 45.50 (subtract 5 on each side)
2.25x = 40.50 (divide by 2.25 on both sides to get the x alone)
x = 18
40.50/2.25 = 18
Answer:
18 Miles
Step-by-step explanation:
If she tipped the driver $5, we need to remove that from the equation. So it's now $40.5.
Now to find the answer all we need to do is divide 40.5 by 2.25, which is 18.

Answer:
x = 3.
Step-by-step explanation:
log4 (3x - 1) = log4 (x + 5) Since they are both logs to the base 4:
3x - 1 = x + 5
2x = 6
x = 3.
On solving the logarithmic equation, we find that x = 3.

It needs to equal 180, and 180-138 is 42
Answer:
The answer is D: 42
Step-by-step explanation:
Angle 7 and angle 138 are supplementary and must add up to 180
Angle 7 is congruent to angle 6 through CPCTC (Corresponding Parts of Congruent Triangles are Congruent)
Angle 7 and 6 are corresponding angles
you must find angle 7 becasue Angle 7= Angle 6
angle 7=x
138-x=180
solve for equation you get
x=42
Angle 7 = 42
so that means that Angle 6 is 42
N entry level technical writer's annual pay is $55,068 based on 52 weeks per year. Due to the economy, his company is having to cut back on the number of weeks that it employs its technical writers. If the firm cuts the work year to 51 weeks but keeps the same rate of pay, how much should the technical writer expect his annual pay to decrease? Round your answer to the nearest dollar.
Answers
Answer:
The technical writer should expect his annual pay to decrease by $1,059

52 weeks = $55,068
51 weeks =
Cross Multiply
51 weeks × $55,068/52 weeks

Are the triangles PQR and RST similar why or why not?
Answers
Answer: The triangles are similar
======================================================
Explanation:
The square markers show that
angle RPQ = angle RST = 90 degrees
So that's one pair of congruent angles. Another pair of congruent angles is what you see in the diagram below. The angles marked in red are congruent alternate interior angles. Alternate interior angles are congruent when we have parallel lines like this.
Since we have two pairs of congruent angles, we can use the AA (angle angle) similarity theorem to prove the triangles congruent.
Answer:
Triangle PQR and RST are both right triangles but they do not share the same side lengths. They also share the same point R, so I would say that they are similar only because they are both right triangles.

An electronics company is changing its internet advertising from a banner advertisement to a pop-up advertisement. The cost of the banner advertisement in dollars is represented by the function C(n) = 0.30n + 5.00 where 'n' is the average number of hits per hour and $5.00 is just a flat-rate cost.
1.) The cost of the pop-up advertisement will double the cost per hit. The equation for this new cost function will be D(n) =
2.) This change does/does not shift the function vertically and/or horizontally.
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Cost function of banner advertisement:
C(n) = 0.30n + 5.00
n = average number of hits per hour
5 = flat rate
From the function, C(n), the cost per hit is the slope value of the function ; which is 0.30
1.) If the cost of pop-up advert will double the cost per hit, the cost function for pop-up advert will be :
D(n) = 2(0.30n) + 5
D(n) = 0.60n + 5.00
B.) This change in cost per hit has resulted in change in slope which is defined as :
[Rise / run = vertical change / horizontal change].
Hence, both vertical and horizontal change has occurred.

Write the equation of the line perpendicular to y=4x+2 and passes though the point (1,1).
Answers
Answer:y=-1/4x+5/4
Step-by-step explanation:
Perpendicular means the slope has to be the negative reciprocal.
Since the slope is currently 4, the perpendicular slope is -1/4.
It also has to pass through the point 1,1 , so you just plug x in which will be
1*-1/4=-1/4. from 1 to -1/4, its 5/4, so that's your b in y = mx+b
The equation will then be y=-1/4x+5/4
