Ben lost half of his candies while walking home. His mom gave him 8 more candies. Now he has
22 candies. How many candies did he have to begin with?

Answer:

write the given equation in a standard form

6x - 2y = 6

-2y = -6x + 6

y = 3x - 3

m = 3

if the lines are perpendicular to each other the product of their gradient is equal to -1

m1 × m2 = -1

3 × m = -1

3m = -1

m = -1/3

y - y1 = m(x - x1 )

y - (-1) = -1/3 ( x - (-3) )

y + 1 = -1/3 (x + 3 )

y + 1 = -1/3x - 1

y = -1/3x - 1 + 1

y = -1/3x

Answer:

y = -8x + 10.

Step-by-step explanation:

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is -8 and the y-intercept is (0, 10), so the equation is y = -8x + 10.

What is graph of a function?

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

Graph of a function f(x) is the collection of all points of the form (x, f(x))

The gross pay of worker this week is $432.325

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Number of money made in one hour = $ 14.35

Number of hours, worked on Monday = 8 hours

Number of hours, worked on Tuesday = 1/2 hours

Number of hours, worked on Wednesday = 8¾ hours

Number of hours, worked on Thursday = 4 hours

Number of hours, worked on Friday = 8¼ hours

Total number of worked = 4 + 8 + 8¼ + 8¾ + 1/2

                                             = 29.5

Total gross pay = 14.35 × 29.5

The aggregate volume of the two rectangular prisms is 330 cubic cm.

The base's area multiplied by the height gives the rectangular prism its volume. So the formula for a rectangular prism's volume is as follows. Using cubic units, the volume of a rectangular prism = length × breadth × height

The volume is going to be the addition of two volumes.

We are going to divide the shape into two.

Volume = length × breadth × height

Section A and section B

Volume = length × breadth × height

Volume of section A is = 2 × 10 × 9

Volume of section A = 180 cm³

Volume = length × breadth × height

Volume of section B is = 3 × 5 × 10

Volume of section B = 150cm³

Total volume = volume of section A + volume of section B

Total volume = 180cm³ + 150cm³

Total volume = 330cm³

Answer:

d) B => b. 0

Step-by-step explanation:

Now we have to,

→ find the y-intercept of the line.

Formula we use,

→ y = mx + b

→ b = y-intercept

Then the y-intercept is,

→ y = mx + b

→ y = (-2/3)x + 0

→ [ b = 0 ]

Hence, the y-intercept is 0.

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Graph C represents the equation y = x + 5.

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Let the equation be y = x + 5

The values of m = 1 and b = 5

The slope of the line exists the value of [tex]$$m_r$[/tex] and the y-intercept exists the value of b.

Slope: 1 and y-intercept: (0, 5)

Any line can be graphed utilizing two points. Select two x values, and plug them into the equation to estimate the corresponding y values.

How to calculate area of rectangle ?

The area of a rectangle is equal to its length times its width. Follow the steps mentioned below to find the area of a rectangle:

Step 1: Note the dimensions of length and breadth from the given data.

Step 2: Find the product of length and breadth values.

Step 3: Give the answer in square units.

Given :

Area = 40x.6y.9z

length of one side = 10 x ³y ³

∵Area of rectangle = length ˣ breadth

∴ 40x.6y.9z  = 10 x ³y ³  × length of other side

length of other side =  [tex]\frac{40x.6y.9z}{10 x^{3} y^{3} } = 4x^{-2} . 6y^{-2} . 9z[/tex]

20 is is equal to 5 multiplied by 4.

5 is equal to 20 divided by 4

Answer:

length = 8 yds

width = 5.5 yds

Step-by-step explanation:

Area of rectangle = l * w

w = width

length = 2w - 3

Substitute l with 2w - 3:

(2w - 3)*w = 44

2w² - 3w = 44

2w² - 3w - 44 = 0

Solve for w (AC method):

2w² + 8w - 11w - 44 = 0

2w(w + 4) - 11(w + 4) = 0

(2w - 11)(w + 4) = 0

w = 5.5 or w = -4

note: length cannot be negative, so w = 5.5 yds

Substitute w with 5.5 in either equation:

5.5 * l = 44 yds²

l = 44/5.5 = 8 yds

or

l = 2(5.5) - 3

l = 11 - 3 = 8 yds

Applying the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.

If two angles are alternate interior angles formed along a transversal on two parallel lines, then their measures are congruent or the same.

Angles on a straight line are angles that lie along a straight line, and the sum of the angles equals 180 degrees.

Given the following:

m∠BFC = 75°

m∠GFC = 38°

∠EFB, ∠BFC,  and ∠GFC are angles on a straight line, therefore:

m∠EFB = 180 - m∠BFC - m∠GFC

Plug in the values

m∠EFB = 180 - 75 - 38

m∠EFB = 67°

Find the measure of angle FBC:

Angles FBC and EFB are alternate interior angles, therefore:

m∠FBC = m∠EFB = 67° [alternate interior angles theorem]

m∠FBC = 67°

In summary, using the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.

The first expression, (5^2*x^6*y^(-7))(5*x^0*y^28)

Step-by-step explanation:

Basically, add up the exponents for each unique base. We have two exponents with bases of 5 in this expression, 5^2 and 5 (which is equal to 5^1). Add the exponents together to get 3, so you have 5^3 = 125.

Add up the exponents for bases of x this time. We have x^6 and x^0. 6 + 0 = 6, so we have x^6.

Finally add up the exponents for bases of y. We have y^28 + y^(-7) = 28 + (-7) = 21, so we have y^21.

(ii) Substituting x=sin²(θ), we have the quadratic ...

  2x² +x -1 = 0

The quadratic formula gives the solutions as ...

  x = (-1 ±√(1 -4(2)(-1)))/(2(2)) = (-1±3)/4 = -1, 1/2

The value of sin(θ) is the square root of these values. √-1 is imaginary, so does not give us any solutions. √(1/2) = (±√2)/2, corresponding to ...

  sin(θ) = (±√2)/2

  θ ∈ {45°, 135°, 225°, 315°}

(i) Substituting as suggested above, we have ...

  [tex]\dfrac{\sin x\tan x}{1-\cos x}=1+\dfrac{1}{\cos x}\\\\\dfrac{\sin^2 x}{\cos x(1-\cos x)}=\qquad\text{substitute for $\tan x$}\\\\\dfrac{1-\cos^2 x}{\cos x(1-\cos x)}=\qquad\text{substitute for $\sin^2 x$}\\\\\dfrac{1+\cos x}{\cos x}=1+\dfrac{1}{\cos x}\qquad\text{cancel the common factor}\\\\1+\dfrac{1}{\cos x}=1+\dfrac{1}{\cos x}\qquad\text{Q.E.D.}[/tex]
