You want the values of x that correspond to y-values of -2, 0, 4, 6, given the relation y = -2/3x +2.
GraphOne way to find the x-values is to read them from a graph of the equation. That is what we have done in the first attachment. This tells us the table is ...
[tex]\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&-2\\3&0\\-3&4\\-6&6\\\cline{1-2}\end{array}[/tex]
Solve for xYou can solve the equation for x, then use that with the given y-values.
y = -2/3x +2
y -2 = -2/3x . . . . . subtract 2
-3/2(y -2) = x . . . . . multiply by -3/2
Using the given y-values, we find the corresponding x-values to be ...
-3/2({-2, 0, 4, 6} -2) = -3/2{-4, -2, 2, 4} = -3{-2, -1, 1, 2} = {6, 3, -3, -6}
These are the values that we obtained from the graph.
For y = {-2, 0, 4, 6}, x = {6, 3, -3, -6}.

Mina is 7 years old. Her older sister is 3 more than 2 times Mina’s age. Mina’s younger sister is 8 less than twice her age. Mina’s mothers age is 10 more than twice of Mina’s sister’s age. Mina’s grandmother is all of the ages of Mina, her older sister, her younger sister, and her mother combined. How old is Mina’s grandmother?
Answers
Answer & Step-by-step explanation:
Let's start by defining some variables:
M = Mina's age
O = Mina's older sister's age
Y = Mina's younger sister's age
A = Mina's mother's age. We can now use the information given in the problem to set up a system of equations:
O = 2M + 3
Y = 2M - 8
A = 2Y + 10
Grandmother's age = M + O + Y + A
We can substitute the first three equations into the fourth equation to get:
Grandmother's age = M + (2M + 3) + (2M - 8) + (2(2M - 8) + 10)
Simplifying this expression, we get:
Grandmother's age = 9M + 9
Finally, we can substitute M = 7 (Mina's age) to get:
Grandmother's age = 9(7) + 9 = 72 Therefore, Mina's grandmother is 72 years old.

Answers
The extraneous solutions of the equation is -2 and 15.
ln stands for logarithm and it is a function that returns the power to which a certain number (base) must be raised to obtain a given value. The logarithm is commonly used to simplify mathematical expressions and can be thought of as an inverse operation to exponentiation.
In this equation, we have two logarithmic expressions on the left and right side. To solve for x, we need to find what number raised to the power of the base (ln), will result in x² - 30 and 13x.
So, if we find the height for one triangle, we can find the height for the other triangle. To do this, we will use the logarithmic property:
ln(aᵇ) = b * ln(a)
Where a and b are any positive real numbers.
Applying this property to both logarithmic expressions, we get:
ln(x² - 30) = ln((x² - 30)^(1/ln)) = 1/ln * ln(x² - 30)
Equating the two, we get:
1/ln * ln(x² - 30) = 1/ln * ln(13) + 1/ln * ln(x)
Dividing both sides by 1/ln, we get:
ln(x² - 30) = ln(13) + ln(x)
Using the logarithmic property, we can simplify further:
x² - 30 = 13 * x
Dividing both sides by x, we get:
x²/x - 30/x = 13
x - 30/x = 13
x² - 30 = 13x
x² - 13x - 30 = 0
This is a quadratic equation and can be solved using the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
Where a = 1, b = -13, c = -30
So,
x = (-(-13) ± √((-13)^2 - 4 * 1 * -30)) / 2 * 1
x = (13 ± √(169 + 120)) / 2
x = (13 ± √289) / 2
x = (13 ± 17) / 2
So,
x = (13 + 17) / 2 = 15 or
x = (13 - 17) / 2 = -2
These are the two solutions to the equation. To check for extraneous solutions, we substitute x = 15 and x = -2 back into the equation and see if it is true.

Given h(x) = -x+4, solve for x when h(x) =0
Answers
Answer:
When h(x)=0, x=4
Step-by-step explanation:
If: h(x)=-x+4
And: h(x)=0
—> We set the equation equal to 0
—> -x+4=0
X=4
Answer:
When h(x) = 0, x would equal 4.
Step-by-step explanation:
Since we know the h(x) function is h(x) = -x + 4, when we're looking for a specific value for the function, we can replace the h(x) with the value we are setting the function equal to. In this case, 0 would replace h(x), and we would have a simple algebraic equation: -x + 4 = 0. Now we can solve for x, which will be equal to -x + 4 = 0 ⇒ -x = -4 ⇒ x = 4. Therefore, when h(x) equals 0, x would be equivalent to 4.

Three equal cubes are placed adjacent to each other in a row. If side of a cube is 2 , then find the total surface area of the cuboid thus formed.
Answers
Total surface area of cuboid is 56 sq.units.
What is Total Surface Area?Total surface area is the total space covered by an object. It includes both top and bottom of an objects.
Let a be the side of the cube, a=2.

The height and column diameter of Nelson's column in London are approximately 50m and 3m respectively.
Answers
The area occupied by the Nelson's column in London is 225πm².
Nelson's Column is a monument in London, England that stands 50m tall and has a diameter of 3m at the base. To find the area that it occupies, we must use the formula for the area of a cylinder.
The formula for the area of a cylinder is A = 2πr² + 2πrh, where r is the radius and h is the height. The radius of Nelson's Column is half of the diameter, or 1.5m.
Plugging these values into the formula, we get
=> A = 2π(1.5m)² + 2π(1.5m)(50m) = 225πm².
Therefore, the area occupied by Nelson's Column is 225πm².

What is the slope coefficient? Is this coefficient significant at a 5% level of significance (alpha=0.05)? (Hint: Check the P-value for weight in the Python output.) See Step 4 in the Python script.
Answers
The slope coefficient in a regression model represents the change in the response variable for a one-unit change in the predictor variable, holding all other predictors constant.
The significance of the slope coefficient is determined by the p-value associated with it in the regression output. A p-value less than 0.05 indicates that the slope coefficient is significantly different from zero at a 5% level of significance, meaning that the predictor variable has a significant effect on the response variable. A p-value greater than 0.05 suggests that the predictor variable does not have a significant effect on the response variable.

Answer:

(3b - 8) + b = 180

Two nearby trees are perpendicular to the ground, which is flat. One of these trees is 10 feet tall and has a shadow that is 5 feet long. At the same time, the shadow of the other tree is 2 feet long. How tall, in feet, is the other tree?
Answers
Answer:
4 feet
Step-by-step explanation:
I'll use ratios:
10 feet tall is to 5 foot shadow as x feet tall is to 2 foot shadow
or
10 / 5 = x /2 Multiply both sides of the equation by 2
20 / 5 = x = 4 feet tall
The height of other tree is 4 foot.

In the inter-quartile graph , the data is contained in about 75% of the total (IQR).
A sort of graph used to show numerical data visually is the box-and-whisker plot. In this graph, the inter-quartile range (IQR) of the data is shown as a rectangular box, and the median is shown as a line extending from the box. The minimum and maximum values of the data are indicated by the whiskers extending from the box. It is clear from the box-and-whisker plot's information that roughly 75% of the data falls inside the inter-quartile range. The first quartile (Q1) is subtracted from the third quartile to determine the IQR (Q3). The median of the lower half of the data is the lower quartile (Q1), and the median of the higher half is the upper quartile (Q3).

What is the angle of elevation?A frequently used idea in relation to height and distance is the angle of elevation, particularly in trigonometry. It is described as a relationship between an oblique line from the observer's eye to an item above his eye and the horizontal plane. This angle eventually develops above the surface. The angle of elevation is made in such a way that it is above the observer's eye, as the name suggests.
Given that, the height of Luke is 6 ft .
