Equation of the line parallel to 4x - y = 5 and passes through (3, 4)​ is

[tex]y=-4x+16[/tex]

Step-by-step explanation:

Slope of line 4x - y = 5 is -4. Since parallel lines have same slopes therefore slope of other line is -4 as well.

Equation of the line that passes through (3, 4)​ and has slope -4 is given as

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-4=-4(x-3)[/tex]

Simplifying it further

[tex]y=-4x+12+4[/tex]

[tex]y=-4x+16[/tex]

Answer:

1440°

Step-by-step explanation:

n = number of sides

n-2 x 180

10 - 2 = 8

8 x 180 = 1440°

Answer: 40 Percent

Step-by-step explanation:

105.6 Inches / 12 inches per feet = 8.8 Feet

8.8/22 annual = .4

.4 x 100 = 40 Percent

The percentage of its average annual snowfall has fallen in Redfield so far is 40 percent.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Redfield receives an annual average snowfall of 22 feet.

We know that, 1 foot = 12 inches

Now, 22 feet = 22×12

= 264

This year Redfield has received 105.6 inches of snow.

Here, percentage = 105.6/264 ×100

= 0.4×100

= 40%

Therefore, so far Redfield has received 40% of snowfall.

Answer:

16(n-1)

Step-by-step explanation:

16(n-1) is the simplest form of 16n-16 because you cannot backtrack any farther. To get to 16n-16, you must have 16(n-1) first. When you distribute, you will have 16n and -16. Put those into an equation, you get 16n-16 which is what you have originally.

______________________________

Note:

 - When doing problems like this, it's best to list out each formula and do the drag down method, and replace methods rather than doing it the entire mathematical way, as doing it that way takes a long time and it's more confusing than it should be.

Equation at the end of Step 1:

Note:

 - The x(d) changes from [tex]x-(-4)[/tex] to [tex]x+4[/tex] because of the 2 negatives rule: When there is 2 negatives next to each other, it automatically changes to being the positive version of of that number or the sum of the 2 numbers.

 - The y(k) changes from [tex]+(-8)[/tex] to [tex]-8[/tex] because when a [tex](+)[/tex] and [tex](-)[/tex] are next to each other, the rule is [tex]+<-[/tex]. The Minus always wins in this type of problem situation.

So the answer is b, [tex]\bold{y=\frac{-7}{x+4}-8}[/tex].

Answer:

y = -1x + 9

Step-by-step explanation:

y=mx+c

Find the gradient: (m)

gradient = change in y ÷ change in x

so, 3 ÷ -3 = -1

Substitute any coordinate into the equation y= -1x + c

eg. (6,3) (x,y)

x=6 and y=3

3 = -1(6) +c

3= -6 + c

Rearrange to make c the subject

C= 3+6 = 9

so y= -1x +9

Answer:

y-6=3/2(x-2)

Step-by-step explanation:

point slope form is y-y1=m(x-x1), where m is the slope and (x1,y1) are numbers.

we have the slope (m) given as 3/2, and the point given as (2,6)

substitute the numbers into the equation

y-6=3/2(x-2)

hope this helps :)

Answer:

slope = - 2, y- intercept = 0

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 = - 2x , that is

y = - 2x + 0 ← is in slope- intercept form

with slope m = - 2 and y- intercept c = 0 ( that is the origin )

Answer:

(x,y) = (2,3)

Step-by-step explanation:

Solving steps:

2y = 6 (Divide both sides)

y = 3 (Substitute the value of y)

2x - 3 = 1 (Solve the equation)

x = 2

(x,y) = (2,3)

Answer:

Since the frame is uniform around the picture, you need to add its width, W, to the sides of the picture. We will manipulate the formula for area, A = L x W. To ease confusion with the chosen variable, I will replace the W with an H for height to be A = L x H.

L = W + 11 + W

H = W + 5 + W

You can see this by drawing a picture with a frame around it. Looking from the top to the bottom, you will have it's width plus the picture plus the width of the frame again. Same thing for the height of the picture. Looking from the far left of the frame and across, you have the width of the frame plus the picture plus the width of the frame again. Now plug these into the area formula and combine like terms.

A = L x H

A = (W + 11 + W) x (W + 5 +W)

A = (2W + 11) x (2W + 5)

Now take the product of the two parenthesis.

I learned to use the FOIL method: multiply First, Outside, Inside, Last.

A = (2W x 2W) + (2W x 5) + (11 x 2W) + (11 x 5)

A = 4W2 + 10W + 22W + 55

A = 4W2 + 32W + 55

Step-by-step explanation:

The quadratic function A in standard form to represent the combined area A of the picture and the frame is  4w²+32w+55.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have,

Nicky wants to surround a painting 5 inches by 11 inches with a frame that is w inches wide.

Then, the width of the painting

w = 5 + w + w

   =2w+5 (w inches wider on both sides)

and, the length of the painting

l = 11 + w + w = 2w+11

So, the area is

Area =  length x width

= (2w+11)(2w+5)

=4w²+22w+10w+55

= 4w²+32w+55

Fiona gets 25 sweets

Step-by-step explanation:

System of Equations

Paul, Fiona, and Pip have some sweets in the ratio 4:5:1. Let's call x,y, and z the number of sweets they have respectively.

The ratios can be written as three separate equations:

[tex]\frac{x}{y}=\frac{4}{5}\qquad\qquad[1][/tex]

[tex]\frac{y}{z}=\frac{5}{1}\qquad\qquad[2][/tex]

[tex]\frac{x}{z}=\frac{4}{1}\qquad\qquad[3][/tex]

Paul has 15 more sweets than Pip, then:

x = z + 15        [4]

Multiplying [3] by z:

x = 4z

Substituing in [4]

4z = z + 15

Subtracting z:

3z = 15

z = 15/3 = 5

Multiplying [2] by z:

y = 5z = 5*5 = 25

Answer:

$0.35 per ounce. (rounded.)

Step-by-step explanation:

you just divide.

The cost of one pound of cereal Joseph Bettino purchased is $2.88.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Joseph Bettino purchased an 11.5-ounce box of cereal for $3.99.

Now, To obtain the cost of per pound of cereal we have to divide the total pounds of cereal by the total amount of money which is,

= $(11.5/3.99)

= $2.88.

So, The cost of one pound of cereal is $2.88 it can also be referred as the unit price of the cereal.
