Are the two following expressions equivalent? ( yes or no ) 24x + 6y and 6(4x + y
Answer:
yes because on the second one you have to use the distribution property (multiply the term outside the parenthesis by the terms inside them)
Step-by-step explanation:
Answer:
Yes.
Step-by-step explanation:
Distribute 6 to (4x+y), and you will get the same expression of 24x+6y.
4x times 6 = 24x
6 x y = 6y
24x+6y
Asa's most recent credit card statement had a balance of $2,622.77. The minimum payment warning box indicates that it will take 12 years to pay off the card if
be makes the minimum payment of $28 per month. If he makes a monthly payment of $100, it will take 3 years to pay off the balance. What will be the percent
increase in total payments if Asa only pays the minimum rather than the $100 per month?
Answer:
12%
Step-by-step explanation:
In order to calculate this we first need to find the total that she would pay if she were to choose either of these options. We do this by multiplying the number of years it would take to pay off the loan by the 12 months in a year, and then we multiply this product by the monthly payment like so...
Minimum Payment:
(12 * 12) * 28 = $4,032
$100 a month payment:
(12* 3) * 100 = $3,600
Now that we have both we need to divide the minimum payment total by the $100 a month payment total to get the percentage increase in decimal form
$4,032 / $3,600 = 1.12
Now we subtract 1 and multiply by 100 to turn this decimal into a percentage
(1.12 - 1) * 100 = 12%
Finally, we can see that if Asa only pays the minimum then she would be paying a 12% increase as opposed to paying the $100 a month

Answer:
[tex] 1\frac{1}{6} [/tex]
Step-by-step explanation:
Given:
[tex] \frac{2}{3}*1\frac{3}{4} [/tex]
Required:
Evaluate
SOLUTION:
To evaluate, we need to convert the mixed fraction to improper fraction, then multiply both fractions together.
Thus:
[tex] \frac{2}{3}*\frac{7}{4} [/tex]
Multiply the numerators together, and multiply the denominators together
[tex] = \frac{2 \times 7}{3 \times 4} [/tex]
[tex] = \frac{14}{12} [/tex]
Simply the fraction by dividing the numerator and denominator by 2
[tex] = \frac{7}{6} [/tex]
[tex] = 1\frac{1}{6} [/tex]

The rule Rx-axis o is applied to the point (-3,-2). Where is the image in the coordinate
Answer:
[tex]Image = (-3,2)[/tex]
Step-by-step explanation:
Given
[tex]Point = (-3,-2)[/tex]
Transformation = Rx-axis
Required
Determine the image
When rule Rx-axis is applied to a point (x,y),
The new coordinate point is (x,-y)
In other words, the y coordinate is negated
So, when rule Rx-axis is applied to
[tex]Point = (-3,-2)[/tex]
The image of the point is
[tex]Image = (-3,-(-2))[/tex]
[tex]Image = (-3,2)[/tex]
At the beginning of the semester, a professor tells students that if they study for the tests, then there is a 55% chance they will get a B or higher on the tests. If they do not study, there is a 20% chance that they will get a B or higher on the tests. The professor knows from prior surveys that 60% of students study for the tests. The probabilities are displayed in the tree diagram.
A tree diagram. Random student to studies for test is 0.6, and to does not study for test is 0.4. Studies for test to Gets B or higher is 0.55; does not get B or higher is 0.45. Does not study for test to Gets B or higher is 0.20; does not get B or higher is 0.80.

Answer:
.54
Step-by-step explanation:
The probability is 33%.
what is probability?The probability is the measure of the likelihood of an event to happen.
Given:
Random student to studies for test is 0.6, and to does not study for test is 0.4.
Studies for test to Gets B or higher is 0.55; does not get B or higher is 0.45.
Does not study for test to Gets B or higher is 0.20; does not get B or higher is 0.80.
P(A) =55%
P(B)= 20%
60% of the students study.
So, the probability that a student studies, and gets B or higher is:
Probability =P(A) * 0.6
P= 55* 0.6
Probability = 33%
Hence, the probability is 33%

(2x - 5) (x^2 + x - 2) =
what would be the slope?
I need help with math homework
Answer:
A. (1, 2) and (4, 3)
B. Slope (m) = ⅓
C. y - 2 = ⅓(x - 1)
D.[tex] y = \frac{1}{3}x + \frac{5}{3} [/tex]
E. [tex] -\frac{1}{3}x + y = \frac{5}{3} [/tex]
Step-by-step explanation:
A. Two points on the line from the graph are: (1, 2) and (4, 3)
B. The slope can be calculated using two points, (1, 2) and (4, 3):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 - 2}{4 - 1} = \frac{1}{3} [/tex]
Slope (m) = ⅓
C. Equation in point-slope form is represented as y - b = m(x - a). Where,
(a, b) = any point on the graph.
m = slope.
Substitute (a, b) = (1, 2), and m = ⅓ into the point-slope equation, y - b = m(x - a).
Thus:
y - 2 = ⅓(x - 1)
D. Equation in slope-intercept form, can be written as y = mx + b.
Thus, using the equation in (C), rewrite to get the equation in slope-intercept form.
y - 2 = ⅓(x - 1)
3(y - 2) = x - 1
3y - 6 = x - 1
3y = x - 1 + 6
3y = x + 5
[tex] y = \frac{1}{3}x + \frac{5}{3} [/tex]
E. Convert the equation in (D) to standard form:
[tex] y = \frac{1}{3}x + \frac{5}{3} [/tex]
[tex] -\frac{1}{3}x + y = \frac{5}{3} [/tex]
A booth at the farmer’s market has fresh goat cheese in three sizes of containers. The big container is 30 ounces and costs $9.00. The medium container is 15 ounces and costs $4.95. The small container is 8 ounces and costs $2.00. What size is the best buy? Justify your reasoning.
Answer:
8 ounce
Step-by-step explanation:
The 30 ounce container costs $0.30 per ounce. The 15 ounce container is $0.33 per ounce. The 8 ounce container is $0.25 per ounce. Therefore, the 8 ounce container costs less per each ounce.
A line has a slope of 6 and includes the points (n,1) and (8,5). What is the value of n?
Answer:
The value of n:
[tex]n=\frac{22}{3}[/tex]Step-by-step explanation:
Given that the line has slope 6.
i.e. m = 6
The line includes the points
(n, 1)(8, 5)Using the formula to find the slope of the points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(n,\:1\right),\:\left(x_2,\:y_2\right)=\left(8,\:5\right)[/tex]
[tex]m=\frac{4}{8-n}[/tex]
as
m = 6
substituting m = 6
[tex]6=\frac{4}{8-n}[/tex]
[tex]6\left(8-n\right)=4[/tex]
Divide both sides by 6
[tex]\frac{6\left(8-n\right)}{6}=\frac{4}{6}[/tex]
[tex]8-n=\frac{2}{3}[/tex]
subtract 8 from both sides
[tex]8-n-8=\frac{2}{3}-8[/tex]
simplify
[tex]-n=-\frac{22}{3}[/tex]
Divide both sides by -1
[tex]\frac{-n}{-1}=\frac{-\frac{22}{3}}{-1}[/tex]
[tex]n=\frac{22}{3}[/tex]
Therefore, the value of n:
[tex]n=\frac{22}{3}[/tex]find the slope of the line please help!

Lucy cuts 5 different pieces of fabric throughout the day .
1.125 M 475CM 245CM 5.875M 3.055M
What is the total amount of fabric she cut ?
(. )M
Answer: 1 625.5cm or 16.255m
Step-by-step explanation:
convert all m measurements into cm by multiplying, add all the cm measurements together. this equation is 12.5cm+ 475cm+ 245cm+ 587.5cm+ 305.5cm= 1625.5cm.
convert the cm measurements back to m measurements (i only assume because you said . m at the end)
The total amount of fabric she cut is 17.255 m .
The total length of the fabric can be determined by adding the length of the different pieces. Addition is determining the total value or summing two or more numbers.
In order to add the different lengths, the lengths have to be in meters.
100cm - 1 meter
475cm = 475 / 100 = 4.75m
245cm = 245 / 100 = 2.45m
Now that all the lengths are in the same units, they can now be added together; 1.125 + 5.875 + 3.055 + 4.75 + 2.45 = 17.255 m

Reflect triangle ABC over the x-axis. Then translate the new triangle 5
units to the left. What are the coordinates of the vertices of the final image?
Answer:
The coordinates of the vertices of the final image will be:
A''(-6, 8), B''(-7, -2), and C''(0, -2)
Hence, option (B) is true.
Step-by-step explanation:
Given the triangle with the vertices
A(-1, -8)B(-2, 2)C(5, 2)We know that when we reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate reverses its sign.Thus,
The rule of reflection across the x-axis:
(x, y) → (x, -y)
so
A(-1, -8) → A'(-1, -(-8)) = A'(-1, 8)
B(-2, 2) → B'(-2, -2) = B'(-2, -2)
C(5, 2) → C'(5, -2) = C'(5, -2)
Then, translate the new triangle 5 units to the left
Rule of translating 5 units to the left
(x, y) → (x-5, y)
so
A'(-1, 8) → A''(-1-5, 8) = A''(-6, 8)
B'(-2, -2) → B''(-2-5, -2) = B''(-7, -2)
C'(5, -2) → C''(5-5, -2) = C''(0, -2)
Therefore, the coordinates of the vertices of the final image will be:
A''(-6, 8), B''(-7, -2), and C''(0, -2)
Hence, option (B) is true.
