Tyler correctly rewrote x^(-3) as ------- , but

                                                       x³

                                                       1

he incorrectly wrote y^(-9) as   ---------

                                                    y^(-9)

Both x^9 and y^9 should be in the denominator.  This corresponds to the 2nd given possible answer.

Answer:

B:Both powers should be in the denominator with positive exponents.

Step-by-step explanation:

We are given that Tyler simplified an expression

[tex]x^{-3}y^{-9}[/tex]

We have to find an error which Tyler makes in her simplification

Step 1: [tex]x^{-3}y^{-9}[/tex]

Step 2:[tex]\frac{1}{x^3}\cdot y^{-9}[/tex]

Step 3:[tex]\frac{1}{x^3y^9}[/tex]

Hence, Tyler's error is both exponents should be denominator with positive exponents.

Answer:B:Both powers should be in the denominator with positive exponents.

This is the following way to solve this problem:

3x-10(x+2)=13-7x

3x-10x-20=13-7x        (multiply 10 times what's in the parentheses)

-7x-20=13-7x              ( subtract 3x from -10x)

-7x-20-13=-7x             ( since the 13 is positive, when we move it to the other

                                   side, we change it's sign, so now we subtract 13 from 20

-7x-7=-7x

-7=-7x+7x                   ( we do the same thing we did above, now with the -7x)

-7=x

x=-7

Answer: x = -7

Step-by-step explanation:

We have two points so we can use the formula for slope

(-3,-2) (1,3)

m = (y2-y1)/(x2-x1)

   = (3--2)/(1--3)

-48x - 96 (multiply -12 by both numbers separately)

Answer:

-48 + -96

Step-by-step explanation:

The product −(1/4⋅1/4⋅1/4⋅1/4) can be written as exponents as - (1/4)⁴.

Exponents are the method of writing numbers, especially large numbers, in terms of a base and an exponent, which is written as the power of base.

Given expression is,

−(1/4⋅1/4⋅1/4⋅1/4)

We have to write the expression using exponents.

Taking the minus sign as such, it is given that three are 4 times 1/4 is repeating.

So, −(1/4⋅1/4⋅1/4⋅1/4) = - (1/4)⁴.

Hence the exponent form of the given expression is - (1/4)⁴.

Final answer:

The expression −(1/4· 1/4· 1/4· 1/4) is written using exponents as −(1/4)⁴.

Explanation:

The expression −(1/4· 1/4· 1/4· 1/4) can be rewritten using exponents by recognizing that we are multiplying 1/4 by itself four times. Converting a repeated multiplication into exponential form means we use a base (which is 1/4 in this case) and an exponent (the number of times we multiply the base by itself). Thus, we write the expression as −(1/4)⁴. The negative sign just indicates that the result should be taken as the opposite (negative) value of (1/4)⁴.

Answer:

Part A: No it is not a function

Part B: The equation

Part C: x = 3

Step-by-step explanation:

Part A - The table:

Input (x)    Output (y)

6                14

12               15

15               15

25              16

This is a function because it has no repeating inputs values which have alternate outputs. Each input is assigned exactly one output.

Part B - The relation y = 7x - 15 has the value y = 27 when x = 6. You can find it by substituting into the equation.

y = 7(6) -15

y = 42 - 15

y = 27

The value of the relation in the table when x = 6 is y = 14. The equation has the greater value.

Part C: To find when y = 6, set it equal to 6 and solve for x.

6 = 7x - 15

21 = 7x

3 = x

Answer:

2/5 an acre

Step-by-step explanation:

We multiply the 5/6 hour by 6/5 to get 1 hour.

We then have to do this to the 1/3 and we get 6/15 or 2/5

Jorge mows 2/5 acres per hour. This is calculated by dividing the fraction of the acre mowed by the fraction of the hour taken. The result from the calculation shows that Jorge’s mowing rate is 2/5 acres per hour.

To find out how many acres Jorge will mow in an hour, we need to determine his mowing rate in acres per hour. We know that Jorge mows 1/3 acre in 5/6 hour. We can use the formula for rate:

Rate = Distance / Time

Here, the distance is 1/3 acre and the time is 5/6 hour. So, we can calculate his rate:

Rate = (1/3) / (5/6)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:

Rate = (1/3) * (6/5) = 6/15 = 2/5

Therefore, Jorge mows 2/5 acres per hour.

There are 10 crosses, which means that there are 10 trees in total. If we distribute 5 gallons among 10 trees, we give each tree

5/10=1/2=0.5 gallons

Answer:

Each tree will get 0.5 gallons of Syrup redistributed to it.

Step-by-step explanation:

According to the line graph shown in the picture there are 10 trees in total.  We have 5 gallons of syrup that needs to be distributed equally among all ten trees. We can solve this by simply dividing the amount of syrup by the amount of trees that will be sharing the syrup.

5/10 = 0.5 gallons each

So each tree will get 0.5 gallons of Syrup redistributed to it.

g(x) = (4/5)x^2 - 2

Step-by-step explanation:

f(x) = (2/5)x^2 - 2 is the equation of a parabola with vertex at (0, -2).

Applying a vertical stretch of factor 2 to f(x) requires multiplying both the slope (2/5) and the y-intercept (-2) by 2:

g(x) = (2)(2/5)x^2 - 4, or

g(x) = (4/5)x^2 - 4.

Answer:

$2,031.08

Step-by-step explanation:

You want to calculate the interest on $1475 at 7.54% interest per year after 5 year(s).

The formula we'll use for this is the simple interest formula, or:

                                                    I=P x r x t

P is the principal amount, $1475.00.

r is the interest rate, 7.54% per year, or in decimal form, 7.54/100=0.0754.

t is the time involved, 5....year(s) time periods.

So, t is 5....year time periods.

To find the simple interest, we multiply 1475 × 0.0754 × 5 to get that:

The interest is: $556.08

Usually now, the interest is added onto the principal to figure some new amount after 5 year(s),

or 1475.00 + 556.08 = 2031.08. For example:

If you borrowed the $1475.00, you would now owe $2031.08

If you loaned someone $1475.00, you would now be due $2031.08

If owned something, like a $1475.00 bond, it would be worth $2031.08 now.

x^2 - 5x - 6  =  (x - 2)(x - 3).

Step-by-step explanation:

f(x) = x^2 - 5x - 6

We need 2 numbers whose product is - 6 and whose sum is -5. They are   -3 and -2:

The factors are x- 2  and x - 3.

Final answer:

The factors of the expression x²-5x-6 are (x-6)(x+1).

Explanation:

This question demands basic understanding of methods of factorization and finding solutions of an equation.

The method to find factors of an equation, ax² + bx + c = 0, find two numbers that multiply to get c and add to give b.

To find the factors of the expression x²-5x-6, we need to factorize it. We look for two numbers that multiply to give -6 and add to give -5. The numbers -6 and 1 fit these conditions.

So, x²-5x-6

=> x² - 6x + x- 6

=> x(x - 6) +1(x - 6)

=> (x - 6)(x + 1)

Therefore, the factors of the expression are (x-6)(x+1).

Answer:

see explanation

Step-by-step explanation:

In order to determine the end behaviour, we only need to look at the term of highest degree, that is the leading term in standard form.

Given

f(x) = [tex]x^{4}[/tex] - 2x² + 1

So the term of highest degree is [tex]x^{4}[/tex]

Which is of even degree with positive coefficient

As a result the end behaviour is

As x approaches positive infinity, f(x) approaches positive infinity

As x approaches negative infinity, f(x) approaches positive infinity

----------------------------------------------------------------------------------------------

Substitute x = - 2 into f(x)

f(- 2) = [tex](-2)^{4}[/tex] - 2(- 2)² + 1 = 16 - 8 + 1 = 9 ≠ 0

Substitute x = - 1 into f(x)

f(- 1) = [tex](-1)^{4}[/tex] - 2(- 1)² + 1 = 1 - 2 + 1 = 0

Thus x = - 1 is a root of f(x) and (x + 1) is a factor of f(x)
