Justine Wants To Factor The Expression 16a+40b By Finding The GCF. How Can You Tell If She Factors Out
Answer 2

Final answer:

To factor the expression 16a+40b by finding the GCF, you determine that the GCF is 8 and then express the original terms as 8(2a + 5b). By distributing the GCF back into the factored terms and obtaining the original expression, you confirm the factorization is correct.

Explanation:

To factor the expression 16a+40b by finding the Greatest Common Factor (GCF), you first list the factors of each coefficient:

Factors of 16 are 1, 2, 4, 8, 16.

Factors of 40 are 1, 2, 4, 5, 8, 10, 20, 40.

The GCF for these two numbers is 8 because it is the highest number that divides both 16 and 40 evenly. Now, you factor out the GCF from both terms in the expression:

8(2a + 5b)

To verify if the GCF is factored out correctly, you can distribute 8 back into the terms within the parentheses. If the original expression is obtained, the GCF was factored out correctly:

8*2a = 16a

8*5b = 40b

Therefore, the factored expression is correct, and Justine has successfully found and factored out the GCF.

Maya and Sally were the two finalists in a singing competition. The person with the most votes from the audience was chosen as th\e winner. Sally received 25% of the total votes and lost by 62,500 votes. No person in the audience was allowed to vote more than once. The equation below represents this situation, where y is the total number of votes cast and x is the number of votes Maya received: x − 62,500 = 0.25y If a total of 125,000 people voted, how many votes did Maya receive? Do not enter comma for placeholder values. Numerical Answers Expected!

Answers

y is the total number of votes, which is given as 125,000

Replace Y in the equation and solve for x.


X - 62500 = 0.25(125000)

Simplify:

x - 62500 = 31250

Add 62500 to both sides:

X = 31250 + 62500

X = 93750


Stu wants to join a gym. Fit-Place charges a $135 startup fee and then $35 per month. The Factory has no startup fee but charges $60 per month. Create a table showing the total cost for the first 8 months. Determine the month at which the total cost is the same.

Answers

I don't know the answer use a calculater

Answer:

Fit-Place charges a $135 startup fee and then $35 per month.

Means the cost here will be based on the equation : [tex]135+35x[/tex] where x is the number of months.

The Factory has no startup fee but charges $60 per month. Here the equation will be [tex]60x[/tex], where x is the number of months.

Table ;

Months              1          2          3        4         5        6          7        8

Fit-Place          170      205     240     275     310     345    380   415

The Factory     60      120        180     240    300    360   420    480

The total cost will be same in:

[tex]60x=135+35x[/tex]

=> [tex]60x-35x=135[/tex]

=> [tex]25x=135[/tex]

x = 5.4 rounded to 5 months.

Now we can see that the total cost will be same in almost 5 months.

Answers

a line through the point (0, 6 )

to find a point on the line, choose any value of x , substitute into the equation and solve for y

x = 0 : 0 + 4y = 24 ( divide both sides by 4 )

y = [tex]\frac{24}{4}[/tex] = 6

hence line goes through (0, 6 )


Final answer:

The correct graph that represents the equation 2x + 4y = 24 is option A, which shows a line through the points (0, 6) and (12, 0).

Explanation:

The equation 2x + 4y = 24 can be rearranged to y = -0.5x + 6. This means that the equation represents a linear function with a slope of -0.5 and a y-intercept of 6.

Option A, which shows a line through the points (0, 6) and (12, 0), is the correct graph since it satisfies the equation. The slope is -0.5 and the y-intercept is 6.

18x^2-2 factor completely

Answers

Here is your answer to your question

The factored form of [tex]\(18x^2 - 2\)[/tex] is [tex]\({2(3x - 1)(3x + 1)}\)[/tex].

To factor the expression [tex]\(18x^2 - 2\)[/tex] completely, we first notice that [tex](18x^2\))[/tex] and [tex]\(2\)[/tex] share a common factor of [tex]\(2\)[/tex]. We can factor out this common factor to simplify the expression:

[tex]\[18x^2 - 2 = 2(9x^2 - 1)\][/tex]

Now, we recognize that [tex]\(9x^2 - 1\)[/tex] is a difference of squares. It can be factored as [tex]\((3x)^2 - 1^2\)[/tex], which follows the pattern [tex]\((a^2 - b^2) = (a - b)(a + b)\)[/tex].

So, applying this pattern, we have:

[tex]\[9x^2 - 1 = (3x)^2 - 1^2 = (3x - 1)(3x + 1)\][/tex]

Therefore, the expression \(18x^2 - 2\) factors completely as:

    For (1,5)

              f(1) =  [tex]2^1=3[/tex], given that f(1) = 5, so option B is wrong.

c) f(x) = [tex]4^x[/tex]

   For (0,1)

              f(0) = [tex]4^0=1[/tex]

    For (1,5)

              f(1) =  [tex]4^1=4[/tex], given that f(1) = 5, so option C is wrong.

d) f(x) = [tex]5^x[/tex]

OK first change 3 3/4 to an improper fraction and that will give you  15/4. so you got that part right.  Next, change the division sign to multiplication. then flip the 1/2 to 2/1.  Then multiply 15 times 2 and that will give you 30. Then multiply 4 times 1 and that will give you 4. then you will have an answer of  30/4. Finally, since you a have a big number over a small number you divide 30 by 4 and that will give you 7 1/2. So it turns out that your little cheat sheet is wrong because when you check your answer you should go on Math-way to check it. Also, a little background about me is that I am in 8th grade and I am taking algebra 1 too.

A case of 24 pairs of the same kind of sports shoes costs a little more than $800.Explain whether $28 per pair with tax included is a good estimate.

Answers

No because 24 times 28 is 672

$28 per pair is not a good estimate.

Step-by-step explanation:

Let x represent cost of each pair with tax.

We have been given that a case of 24 pairs of the same kind of sport shoes cost a little more than $800.

The cost of 24 pairs would be [tex]24x[/tex].

[tex]24x>800[/tex]

Are angles 2 and 5 vertical angles, linear pairs or neither? Thank you :)

Answers

Vertical angles. Vertical angles are two angles that equal the same and are directly across from each other. In this case, if you find the value of 2 then 5 would be the same.
Final answer:

Without more information or a diagram showing the arrangement of the angles, we can't accurately determine if angles 2 and 5 are vertical angles, linear pairs, or neither. Vertical angles are those opposite each other when lines intersect and are always equals, while a linear pair of angles add up to 180 degrees and share a vertex and a side.

Explanation:

To determine if angles 2 and 5 are vertical angles, linear pairs, or neither, we need to know the positional arrangement of these angles.

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in degree.

A linear pair of angles is formed when two angles add up to 180 degrees and they share a vertex and a side.

Without a diagram or more context, it's impossible to determine the relationship between angles 2 and 5. Please provide more information or a diagram to help identify the relationship between these angles.

Answer:

The midpoint of AB is (0.5,1).

Step-by-step explanation:

From the given graph it is clear that the vertices of the triangle ABC are A(-2,5), B(3,-3) and C(-4,-1).

If end points of a line segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the midpoint of that segment is

[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Final answer:

To find the total tax on Edward Taylor's purchases, sum the cost of all items ($164.25), multiply by the combined tax rate of 8.5% to get the total tax in dollars ($13.96125), and round to the nearest cent, resulting in $13.96. So, option C is correct.

Explanation:

To determine the total amount of tax on Edward Taylor's purchases, we need to sum up the cost of all items purchased and then calculate the combined sales tax. Edward bought two shirts for $17.95 and $27.50, a jacket for $94.20, and two ties at $12.30 each. Here are the steps taken:

Calculate the sum of the purchases: $(17.95 + 27.50 + 94.20 + 12.30 + 12.30) = $164.25.

Combine the tax rates: (state tax at 5% + county tax at 1.5% + city tax at 2%) = 8.5% total.

Convert the tax rate to a decimal: 8.5% = 0.085.

Multiply the total cost of purchases by the tax rate: $164.25 * 0.085 = $13.96125.

Round the tax to the nearest cent: $13.96.

Therefore, the total amount of tax on his purchases is $13.96. So, option C is correct.
