Factor quadratic equation 6x.squared +41x + 63 = 0
Answers
Answer:
x1= -9/2 ; x2= -7/3
Step-by-step explanation:
Rewrite to 6x^2 + 27x +14x +63 = 0
Factor and get 3x(2x + 9) + 7(2x + 9) = 0
Factor again and get (2x + 9)(3x + 7) = 0
Separate into possible cases -> 2x + 9 = 0; 3x + 7 = 0
The equation has two solutions: x1 = -9/2 and x2 = -7/3

An open circle is used to graph strict inequalities, which means the inequality does not include the value at the boundary. The inequalities that would have an open circle when graphed are:
x > 5.4
One-half less-than x
x > 0
if an inequality states less than OR equal to that means the circle will be closed when graphed

Explanation:
We have these three rules for scale factors
scale factor > 1, enlarge the image0 < scale factor < 1, shrink the imagescale factor = 1, the preimage and image are identicalWith those rules in mind, we have enlargements for these transformations.
P to QP to RQ to RAll of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.
In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.
----------------
We also have these reductions
Q to SR to PThis is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.
----------------
And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.
P to SS to PThe order doesn't matter for this subset, but the order will matter for the other batches of transformations.

Answer:
\(13.5 m^{2}\)
Step-by-step explanation:
area = length × width
= 15m × 9/10m
= 15m × 0.9m
= \(13.5 m^{2}\)
Answer:
\(\Huge \fbox{Area = 13.5 m^{2}$}\)
Step-by-step explanation:
To find the area of the baseboard, we need to multiply the length by the width:
The length of the baseboard is given as 15 metres. The width of the baseboard is given as \(\frac{9}{10}\) metre.To multiply these values, we can convert the width to a decimal by dividing the numerator (9) by the denominator (10):
\(\frac{9}{10} = 0.9\)Now we can multiply the length and width:
\(\text{Area = Length $\times$ Width}\)\(\text{Area = 15 m $\times$ 0.9 m}\)\(\text{Area = 13.5 m^{2}$}\)Therefore, the area of the baseboard is 13.5 m².

Identify the slope and y-intercept of the graph of the equation. y = 5/3 x -2
Answers
Answer:
Slope: \(\frac{5}{3}\)
Y-intercept: -2
Step-by-step explanation:
Conveniently, this equation is already in slope-intercept form.
The slope is always the constant of proportionality, which we multiply x by.
Therefore the slope is \(\frac{5}{3}\).
The y-intercept is always the constant that comes after the x term, which is -2.
So the y-intercept is -2.
Hope this helped!
Answer:
Slope: 5/3
Y-intercept: -2
Step-by-step explanation:
Since your equation is already in slope intercept form, it makes it easier for you to identify the slope and y-intercept.
In your equation (\(y = \frac{5}{3} x -2\)) the coefficient of 5/3 is your slope and your constant of -2 is your y-intercept.

Amal usually brings lunch to the school in the lunch box shown below. The length, breadth, and height of the box are in the ratio of 2:3:4 and the sum of the cubes of length, breadth, and height of the box equals 33957 cm³.
Find the length of the longest edge of the box.
Find the sum of the length and breadth of the box.
Answers
Answer: length of longest side = 15092 cm
sum of length and breadth = 18856 cm
Step-by-step explanation:
1st question
length : breadth : height
2 : 3 : 4
2 + 3 + 4 = 9
33957 ÷ 9 = 3773
longest side is the height because it has the biggest number in the ratio
∴ longest side = 4 × 3773 = 15092 cm
2nd question
length : breadth : height
2 : 3 : 4
2 + 3 + 4 = 9
33957 ÷ 9 = 3773
→ length = 2 × 3773 = 7546 cm
→ breadth = 3 × 3773 = 11319 cm
∴ length + breadth = 7546 + 11319 = 18865 cm
Hope this helps!
The Length of longest edge of the box = 28 cm
The Sum of length and breadth of the box = 35 cm
Steps to calculate the length, breadth and height
Given, ratio(length : breadth : height) = (2:3: 4)
Let length = 2x, breadth = 3x and, height = 4x
Given, the sum of the cubes of length, breadth, and height of the box equals 33957 cm, therefore
\((2x)^3\) + \((3x)^3\) + \((4x)^3\) = 33957
8\(x^{3}\) + 27\(x^{3}\) + 64\(x^{3}\) = 33957
99\(x^{3}\) = 33957
\(x^{3}\) = 343
\(x^3\) = \(7^3\)
x = 7.
Therefore, length = 2x = 2*7 = 14 cm, breadth = 3x = 3*7 = 21 cm, height = 4x = 4*7 = 28 cm. Hence, Length of longest side(height) = 28 cm, Sum of length and breadth = 35 cm

Answers
Answer:
i need help with this one also
Step-by-step explanation:
Perks A Lot typically sells more coffee per hour than Wide Awake.
What is mean?
The mean is a measure of central tendency that represents the average value of a set of numerical data. It is calculated by adding up all the values in the data set and dividing by the total number of values.
To determine which coffee shop typically sells the most amount of coffee per hour, we need to compare the measures of center for the two data sets. The two common measures of center are the mean and median.
The mean is calculated by adding up all the values and dividing by the total number of values. The median is the middle value when the data is arranged in order.
Using a calculator or spreadsheet, we can find the mean and median values for each coffee shop:
Perks A Lot:
Mean = (10+3.5+3+5+2.5+7+8+5.5+9.5+6+9+4.5) / 12 ≈ 5.75 gallons
Median = 5.75 gallons
Wide Awake:
Mean = (2.5+10+4+18+4+3+6.5+15+6+5+2.5) / 11 ≈ 4.5 gallons
Median = 4.5 gallons
From the calculations, we can see that Perks A Lot has a higher mean and median value than Wide Awake. Therefore, Perks A Lot typically sells more coffee per hour than Wide Awake.
Thus, we can use the mean or median as the measure of center to compare the two coffee shops, and both measures show that Perks A Lot typically sells more coffee per hour.

Which of the following combinations of side lengths will form a triangle with vertices X, Y, and Z?
(A.) XY = 18 mm , YZ = 20 mm , XZ = 39 mm
(B. ) XY = 17 mm , YZ = 20 mm , XZ = 36 mm
(C.) XY = 16 mm , YZ = 20 mm , XZ = 37 mm
(D.) XY = 17 mm , YZ = 19 mm , XZ = 37 mm
Answers
Answer:
(A.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 18 mm, YZ = 20 mm, and XZ = 39 mm. This is because the sum of the lengths of any two sides of a triangle must be greater than the length of the third side according to the triangle inequality theorem. In this case, XY + YZ = 18 mm + 20 mm = 38 mm, which is greater than XZ = 39 mm, satisfying the triangle inequality theorem.
(B.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 17 mm, YZ = 20 mm, and XZ = 36 mm. This is because XY + YZ = 17 mm + 20 mm = 37 mm, which is greater than XZ = 36 mm, satisfying the triangle inequality theorem.
(C.) A triangle will not be formed with vertices X, Y, and Z with side lengths XY = 16 mm, YZ = 20 mm, and XZ = 37 mm. This is because XY + YZ = 16 mm + 20 mm = 36 mm, which is not greater than XZ = 37 mm, violating the triangle inequality theorem.
(D.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 17 mm, YZ = 19 mm, and XZ = 37 mm. This is because XY + YZ = 17 mm + 19 mm = 36 mm, which is greater than XZ = 37 mm, satisfying the triangle inequality theorem.
