If m/FEG is 3x - 11 and m/CBH is x + 27, what is the value of x?
Answer:
x= 19
Step-by-step explanation:
I believe you would put both expressions equal to each other. So,
3x-11= x+27
3x-x=27+11
2x=38
x= 38/2

If you have a garden that is 5m x 8m and there are 120 pepper plants, what is the population density of the pepper plants?
Three pepper plants are present per population density.
How do you calculate population density?You must divide the population by the area's size to determine the population density. Population Density is therefore equal to the number of people divided by the land area.
Since we are working with plants here, the formula is as follows:
Population Density = Plants Per Unit Area
Given,
There are 120 plants.
Area of Land = 5 x 8
= 40 m^2
Just enter the values into the formula now.
Number of People = 120/40
= 3
Consequently, the number of pepper plants per square foot is 3.

What is the equation of a line that passes through (8,-5) and is parallel to the graphed line? In a linear graph line diagram, A line passes through (minus 4, minus 6) and (8, 3) which intersects the x-axis at 4 units and the y-axis at minus 3 units.
The formula for the line that intersects at (8,-5) and is parallel to line x+y = 8 is given by the algebraic expression y = -x +3.
What is Algebraic expression?
The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. Variables and constants can both be used in an algebraic expression.A coefficient is any quantity that is added before a variable and then multiplied by it.The Algebraic expression in this case is:
x + y = 8
which traverses points (8,-5)
Let's start by utilizing the point-intercept equation of line, which is provided by: to determine the slope of line m, that is parallel towards the line x + y = 8.
y = mx + c →(1)
x + y = 8
y = -x + 8
Comparing the aforementioned Algebraic expression to equation (1), we obtain
m = -1
The slope of the line parallel to the line x + y = 8 will now be the same, and it will be m = -1.
Let's use the point-slope equations of line to determine the linear equation now:
(y-y₁) = m(x-x₁)
Changing every value in the equation above to obtain the Algebraic expression for a line
(y-(-5)) = -1(x-8) (x-8)
(y+5) = -x+8
y + 5 = -x +8
y = -x +3

The function 1500x+y=35000 represents the altitude in feet, y, of a passenger airplane after x minutes of its descent.
PART A: Which graph represents the passenger airplane’s altitude?
By identifying the y and x-intercepts of the linear equation, we conclude that the correct graph is the third one
Which graph represents the altitude?We know that the relation between altitude and time is given by the linear equation:
1,500x + y = 35,000
If we isolate y, we get:
y = -1,500x + 35,000
Notice that when x = 0, we have:
y = -1,500*0 + 35,000
y = 35,000
So the y-intercept is 35,000
And the plane reaches the ground when:
0 = -1,500*x + 35,000
1,500*x = 35,000
x = 35,000/1,500 = 23.3
So it intercepts the x-axis at x = 23.3
With that in mind, we can see that the correct graph is the third one.

Show whether or not each pair of triangles are similar, if possible. Justify your answer, and write a similarity statement when the triangles are similar.
If the matching sides and angles of two triangles are proportional, then the triangles are said to be similar.
Triangles that share the same form but differ in size are said to be similar.
Examples of related objects are all equilateral triangles and squares with any side length. In other words, two similar triangles have similar sides that are proportionately equal and similar angles that are congruent. Three triangle-specific theorems can be used to easily identify between related triangles. SSS, SAS, ASA, AAS, and HL are the five ways to determine whether two triangles are congruent.SSS (side, side, side) (side, side, side) SSS, which stands for "side, side, side," denotes that there are two triangles with equal sides. . AAS (angle, angle, side), ASA (angle, side, angle), SAS (side, angle, side), and HL (angle, angle, side) (hypotenuse, leg)Hence from the above properties we can find if any two triangles are similar.

The quadratic function to model the values in the table will be,
y = 3x² + 3x - 3
Option 1 is true.
What is Quadratic equation?
An algebraic equation of the second degree in x is called Quadratic equation.
Given that;
The values of x and y are,
x = -1, 0, 3
y = -3, -3, 33
Let a quadratic function is,
y = ax² + bx + c ... (i)
Then, It satisfy all the values given in table.
So, Substitute point (x, y) = (-1, -3) in equation (i) we get;
- 3 = a - b + c ... (ii)
And, Substitute point (x, y) = (0, -3) in equation (i) we get;
-3 = c .. (iii)
And, Substitute point (x, y) = (3, 33) in equation (i) we get;
33 = 9a + 3b + c ... (iv)
Now, Substitute c = -3 from (iii) in equations (ii) and (iv) we get;
From (ii);
- 3 = a - b - 3
a - b = 0 ... (v)
From (iv);
33 = 9a + 3b - 3
Divide by 3;
11 = 3a + b - 1
3a + b = 12 .... (vi)
Solve equations (v) nd (vi) we get;
a = 3 and b = 3
Thus, Substitute the values a = 3, b = 3 and c = -3 in quadratic equation we get;
y = ax² + bx + c
y = 3x² + 3x - 3

The perfect match leading coefficient for the given polynomial will be as below:-

B. P(x) = (x-2)(2x - 3)(4x + 7) => 3. 4

E. P(x) = (x + 2)(2x - 3)(4x + 7) => 4. 2
Leading Coefficient:
The leading coefficient of the polynomial is means the coefficient of the variable having the highest power in the polynomial.
Given,
Here we have the following list of polynomials,
A. P(x) = (x + 2)(2x - 3)(4x + 7)
B. P(x) = (x-2)(2x - 3)(4x + 7)
C. P(x) = 5(x-2)(2x - 3)(4x + 7)
D. P(x) = -(x-2)(2x - 3)(4x + 7)
E. P(x) = (x + 2)(2x - 3)(4x + 7)
Now, we need to find the matching leading coefficients for this polynomials.
In the given polynomials, we have to calculate the highest power variable in each polynomial with the coefficient. That coefficient is known as the leading coefficients.
First, we have to take the expression A, then we get,
A. P(x) = (x + 2) (2x - 3) (4x +7)
Here we have to multiply the x term alone to get the leading coefficient,
P(x) = (x)(2x) (4x)
Thus will results the leading coefficient as P(x) = 8x³
Similarly, for expression B,
P(x) = 1/2(x - 2) (2x - 3) (4x + 7)
P(x) = 1/2(x) (2x)(4x)
P(x) = 1/2 8x³
P(x) = 4x³
For expression C,
P(x)= 5(x - 2) (2x - 3) (4x + 7):
P(x) = 5(x)(2x)(4x)
P(x)= 40x³
For expression D,
P(x) = -(x - 2) (2x - 3) (4x + 7):
P(x) = -(x)(2x)(4x)
P(x) = -8x³
Finally, for the expression E,
P(x) = 1/4(X + 2) (2x - 3) (4x + 7):
P(x) = 1/4(x)(2x(4x)
P(x) = 2x³
Therefore, the corresponding leading coefficients are 8, 4, 40, -8, and 2 respectively.
