Write an equation of the line that passes through the given point and is perpendicular to the given line.
(–6, –4); y = 1/3x + 1
Group of answer choices
y = -1/3x + 1
y =1/3x – 22
y = -3x + 14
y = -3x – 22
Answer:
y = - 3x - 22
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}{3}[/tex] x + 1 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/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}{3} }[/tex] = - 3 , then
y = - 3x + c ← is the partial equation
To find c substitute (- 6, - 4) into the partial equation
- 4 = 18 + c ⇒ c = - 4 - 18 = - 22
y = - 3x - 22 ← equation of perpendicular line

Javier works at a print shop. He starts printing at 8:00 a.m. The number of printed brochures is a linear function of the number of minutes since Javier started printing. By 8:50 a.m. he had printed 240 brochures, and by 9:00 a.m. he had printed 288. Write an equation in the form y = mx + b that represents the number of brochures, y, that were printed after x minutes.
Answer:
y = 4.8(x) + 0
Step-by-step explanation:
In this question, Javier managed to print 240 brochures in 50minutes from 8:00 to 8:50. If we divide these values we see that he printed 4.8 brochures per minute. The same result is given for the 10 minutes from 8:50 to 9:00 where he printed 48 brochures. Therefore, we can get the following linear formula from these values.
y = 4.8(x) + 0
In this case, b would equal 0 because Javier is starting from 0 brochures made when he gets to work at 8:00 a.m
Which property of equality would be used to isolate the variable b in this equation?
3/4 x b = 12
A. addition property of equality
В. subtraction property of equality
C. multiplication property of equality
D. symmetric property of equality
Answer:
C. multiplication property of equality
Step-by-step explanation:
3/4b = 12
Multiply each side by 4/3 using the multiplication property of equality
4/3* 3/4b = 12*4/3
b = 16

Yes , the series is an arithmetic sequence of common difference 2
What is Arithmetic Progression?
An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the number of terms n = 20
The number of tiles in the first row = 10 tiles
The number of tiles in the second row = 2 more than first row
The number of tiles in the second row = 12 tiles
The number of tiles in the third row = 14 tiles
So , the sequence will be , 10 , 12 , 14 , 16 ...
The number of terms n = 20
The first term a = 10
The common difference d = second term - first term
The common difference d = 12 - 10 = 2
The series is an arithmetic sequence and the 20th term of the sequence will be
a₂₀ = a + ( n - 1 )d
a₂₀ = 10 + ( 19 ) 2
a₂₀ = 10 + 38
a₂₀ = 48 tiles
Hence , the series is an arithmetic sequence

how many metres of wire is needed to fence a circular pond of radius 7.7m if the fence is to have three strands of wire all the way around .Give your answer correct to one decimal place. (Take pi is 3.14)
Find the circumference of the pond:
Circumference = 2 x pi x radius
Circumference = 2 x 3.14 x 7.7 = 48.356 m
You want to go around 3 times so multiply the circumference by 3:
48.356 x 3 = 145.068m
Rounded to 1 decimal = 145.1m

What is 4,327 rounded to the nearest thousand?
Answer: 4,000
Step-by-step explanation: To round 4,327 to the nearest thousand, we first find the digit in the rounding place, which in this case is the 4 in the thousands place. Next, we look at the digit to the right of the 4, which is 3.
According to the rules of rounding, since the digit to
the right of the rounding place is less than 5, we round down.
So the 4 in the rounding place stays the same
and all digits to the right of the 4 become 0.
So 4,327 rounded to the nearest thousand is 4,000.

Answer:
x = 7, EF = 10, FG = 12
Step-by-step explanation:
EF = 4x - 18
FG = 3x - 9
EG = 22
EG = 22
EF + FG = 22
4x - 18 + 3x - 9 = 22
4x + 3x - 18 - 9 = 22
7x = 22 + 18 + 9
7x = 49
x = 7
EF = 4x - 18
EF = 4*7 - 18
EF = 28 - 18
EF = 10
FG = 3x - 9
FG = 3*7 - 9
FG = 21 - 9
FG = 12
Determine if the expression -5y^5-y^3 is a polynomial or not. If it is a polynomial, state the type and degree of the polynomial.
Answer:
Yes, it is a polynomial, and the degree is 5
Step-by-step explanation:
A polynomial is a combination of terms separated using + or − signs and normally have exponents. So, this equation is a polynomial. The degree is just the highest exponential value, which is 5 because -5y is being raised to the 5th power

Louis bought 16 cookies at the bakery. He had a
coupon for $7 off his entire purchase. He ended up
paying $13.32. Write an equation to find how much
each cookie originally cost.
Answer:
16x -7 =$13.32
Step-by-step explanation:
$13.32 + $7 = $20.32
$20.32 divided by 16 = $1.27
each cookie cost $1.27
I really hope this help
Answer:- 16x - 7 = 13.32
Also cost of each cookie = $1.27
Explanation:
Let the cost of each cookies be x
ATQ
16x -7 = 13.32
We will mutiply x with 16 because he purchased 16 cookies.
Also he had coupon of $7 which means $7 off which is why -7
And 13.32 is the amount he paid
Now lets solve it
16x - 7 = 13.32
16x = 13.32 + 7
16x = 20.32
x = 20.32/16
x = 1.27
Therefore cost of each cookie is $1.27
