Answer:

y = -1/2x - 1

Step-by-step explanation:

Hi there!

We are given the equation y = -1/2x - 5

We want to write an equation parallel to this line, that passes through the point (4, -3)

Parallel lines have the same slope

In y=-1/2x-5, the equation is written in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

-1/2 is in the place of where m is, therefore it is the slope of the line

It is also the slope of the new line that we want to create.

As we already know the slope of this new line, we can substitute it into our equation (y=mx+b):
y=-1/2x+b
Now we need to solve for b

As the equation passes through the point (4, -3), we can use its values to help solve for b

Substitute 4 as x and -3 as y:

-3 = -1/2(4)+b

Multiply

-3 = -2+b

Add 2 to both sides

-1 = b

Now substitute -1 as b into the equation

y = -1/2x -1

Hope this helps!

Answer:

  a) 32

  b) 2 +5n

Step-by-step explanation:

Given the stick patterns shown, with 7, 12, 17 sticks, you want to know (a) the number of sticks in pattern 6, and (b) the number of sticks in pattern n.

The numbers of sticks in the patterns shown are ...

  7, 12, 17

The differences between these numbers are ...

  12 -7 = 5

  17 -12 = 5

That is, the first pattern has 7 and the common difference between patterns is 5. This indicates the sequence is arithmetic.

The general term of an arithmetic sequence with first term a1 and common difference d is ...

  an = a1 +d(n -1)

  an = 7 +5(n -1) = 7 +5n -5

  an = 5n +2 . . . . . . sticks in pattern n

The term when n=6 is ...

  a6 = 5·6 +2 = 32 . . . . . . sticks in pattern 6

Additional comment

We find it easier to determine sticks in pattern 6 by first determining the formula for pattern n.

Remark

There are two ways of calculating % error. Chemistry uses one way. Most others use the second method. I have used the second method.

Measurements

L = 10 in

w = 9 in

h = 4.5 in

Estimated result

350 cubic cm

Solution

Find the volume from the measurements of the Prism

V = L * w * h

V = 10 * 9 * 4.5

V = 405 in^3

Percent Error

% error = 100 * (Calculated Value - Estimated value)/(Estimated Value)

% error = 100 * (405 - 350)/350

% error = 100 * ( 55) / 350

% error = 15.71      

% error = 15.7      (rounded)

Answer:

x < 5

Step-by-step explanation:

the open circle above 5 means that x cannot be equal to 5

the arrow points left indicating values of x are less than 5 , then

x < 5

The required inequality for the given line is x < 5.

Inequality shows relation between two expression which are not equal to each others.

According to the given line,

The value of x is less than 5, implies that x can be 5 to -∞

Also, at x = 5, there is an open circle, implies that,

The value of x can not be equal to 5.

So the inequality can be written as,

x<5

The inequality is x<5 for the given line.

The average thickness of a chicken eggshell being 0.000356 m is written as a single digit times an integer power of 10 as: 4 × 10^{-4} (approx)

The number is written in the form  [tex]a \times 10^b[/tex] where we have [tex]1 \leq a < 10[/tex]

The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).

Scientific notations have some of the profits as:

Better readability due to compact representation

Its value in terms of power of 10 is known, which helps in easy comparison of quantities differing by a large value.

We're given that:

Average thickness of a chicken eggshell = 0.000356 m

We can rewrite it as:

[tex]0.000356 = \dfrac{356}{1000000} = \dfrac{3.56}{10000}= \dfrac{3.56}{10^4} = 3.56 \times 10^{-4}[/tex]

Since we need to write it as a single digit times an integer power of 10, therefore, we get:
[tex]3.56 \times 10^{-4} \approx 4 \times 10^{-4}[/tex]

Thus, the average thickness of a chicken eggshell being 0.000356 m is written as a single digit times an integer power of 10 as: 4 × 10^{-4} (approx)

Answer: x/8

Step-by-step explanation:

take the length of the board and divide it by 8

Answer: There were 7 children

Step-by-step explanation:

Let's use x to represent the children and y to represent the adults.

We know they combine to make a group of 25 people so x+y=25

We also know that they paid $201 and that there is $3 per child and $10 for adults so 3x+10y=201

I will solve by substitution.

Solve for y in the first equation

[tex]x+y=25\\x-x+y=25-x\\y=25-x[/tex]

Sub in our value for y into the other equation and solve for x

[tex]3x+10y=201\\3x+10(25-x)=201[/tex]

Step 1) Simplify

[tex]3x+250-10x=201\\-7x+250=201[/tex]

Step 2) Subtract 250 from both sides

[tex]-7x+250-250=201-250\\-7x=-49[/tex]

Step 3) Divide both sides by -7

[tex]\frac{-7x}{-7} =\frac{-49}{-7}\\x=7[/tex]

Answer:

7 children.

Step-by-step explanation:

Let c = children

Let a = adults

1) We can set up two equations and solve them simultaneously using substitution or elimination method.

c + a = 25

3c + 10a = 201

2) I will use substitution. Make one of the variables the subject; then, substitute it into the other equation.

a = 25 - c

3c + 10(25 - c) = 201

3) Solve for c; then, substitute it into one of the equations.

3c + 250 - 10c = 201

-7c = 201 - 250

-7c = -49

c = -49/-7

c = 7

Let's substitute it into one of the equations.

7 + a = 25

a = 25 - 7

a = 18

Since the question only asked for the number of children, the answer is 7.

Answer:

4 terms

Degree of the 4th term = 5

Coefficient of the 2nd term = -6

Degree of the polynomial = 11

Step-by-step explanation:

Terms of polynomials:  parts of the expression that are separated by the addition or subtraction operation.

Therefore, there are 4 terms in this polynomial.

If a term of the polynomial has more than one variable, then to calculate the degree of that term, add the powers of all the variables in the term.

Therefore, the degree of the fourth term is:

[tex]-\dfrac43x^3y^2 \implies \textsf{degree}=3+2=5[/tex]

The coefficient is the constant.  Therefore, the coefficient of the second term is -6

Degree of a polynomial:  The greatest exponent of a variable in the polynomial equation.

As some of the terms in this polynomial have more than one variable, we must first calculate the degrees of the individual terms, and then select the greatest as the degree of the polynomial equation.

[tex]-2x^9 \implies \textsf{degree}=9[/tex]

[tex]-6x^2y^6 \implies \textsf{degree}=2+6=8[/tex]

[tex]9x^7y^4 \implies \textsf{degree}=7+4=11[/tex]

[tex]-\dfrac43x^3y^2 \implies \textsf{degree}=3+2=5[/tex]

Therefore, the greatest degree is 11, so this is the degree of the polynomial.
