B) y = –x + 9
C) y = x + 11
D) y = x – 7
Answer:
the answer is B) y=-x+9

AB: 6 unitsAC: 8 unitsFrom tangent definition:
tan(β) = opposite/adjacent
where β is some angle, and opposite and adjacent are the opposite and adjacent sides (or legs) to that angle.
In our case, B is the angle, opposite to angle B is side AC, and adjacent to angle B is side AB. Replacing with data:
tan(B) = AC/AB

Which of the following are reasons used in the proof that the equilateral triangle construction actually constructs an equilateral triangle?
Answer:
B. and D.
Step-by-step explanation:
We have that an equilateral triangle is a regular polygon, that is to say, it has its three equal sides.In traditional Euclidean geometry, the equilateral triangles are also equiangular, that is, the three interior angles are equal and measure 60 °. By symmetry of the equilateral triangle, we have to:
Any two equilateral triangles are similarly congruent, therefore:
B. Two segments that are both congruent to a third segment must be congruent to each other
and D. All of the radio of a circle are congruent, are the correct answers.

5y^2 - 2 = 3y
Answer:
y= -2/5 and y=1
Step-by-step explanation:
Start by transforming the equation to your liking:
[tex]5y^2-2=3y\\5y^2-3y-2=0\\[/tex]
Now we have to factor! To do this we have to find common numbers. Do this by multiplying -2 and 5 to get -10. Now think about which two numbers add multiply to be -10 but also add up to be -3 (I got this number from the middle of the equation). The two numbers you should've got are -5 and 2.
Now substitute those two number in place of the middle term, which is -3y like so:
[tex]5y^2-5y+2y-2 =0[/tex]
Now solve the equation in pieces... find the greatest common factor from [tex](5y^2-5y)[/tex] and the greatest common factor from [tex](2y-2)[/tex] . The two common factors for both of those are 5y and 2. Your equation should now look like this:
[tex]5y(y-1)[/tex] + [tex]2(y-1)[/tex]
The two greatest common factors become into one group and the other equation that they have in common (y-1) is it's own equation:
[tex](5y+2)(y-1)=0[/tex]
Now equal both of the equations to 0 and solve for y to get both of the values of y.

(1.32 +0.412 – 241) – (0.612 + 8 - 181)
What is the additive inverse of the polynomial
being subtracted?
-0.612 + (-8) + (-181)
-0.612 + (-8) + 18+
-0.612 + 8 - 181
0.612 + (-8) + 181
DONE
Answer:
The additive inverse of the polynomial being subtracted is -0.612-8+181
Step-by-step explanation:
Given expression : (1.32 +0.412 – 241) – (0.612 + 8 - 181)
Now the polynomial being subtracted : (0.612 + 8 - 181)
Additive inverse : The number in the set of real numbers that when added to a given number will give zero.
So, Additive inverse of 0.612 = -0.612
Additive inverse of 8 = -8
Additive inverse of -181 = 181
So, The additive inverse of polynomial being subtracted : -0.612-8+181
So, Option B is true
Hence the additive inverse of the polynomial being subtracted is -0.612-8+181

The given triangle TVW is dilated according to the rule D (3/4)(x,y)=((3/4)x, (3/4)y) to create the image triangle T'V"W", which is not shown.
From the attached image; the coordinates of endpoints T and V are;
T(-4, 8) and V(0, 4)Therefore, the result segment of the dilation according to the rule; D (3/4)(x,y)=((3/4)x, (3/4)y) is;

Answer:
150 m
Step-by-step explanation:
Since we have a dome inscribed in a rectangle, and are given the width of the rectangle, we can,
1. Find the diameter of the circle, which is also 150m
2. Find the length of the rectangle, which is 75m (the length of the rectangle is the same as the radius of the circle)
If we are to find the perimeter of the shaded region, we add the length and half the width of the rectangle. So,

Calculate the area of this trapezium
Answer:
72 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 6 , a = 15, b = 9 , thus
A = [tex]\frac{1}{2}[/tex] × 6 × (15 + 9) = 3 × 24 = 72 cm²
Answer:
= 72 cm²
Step-by-step explanation:
A = (b + B)×h/2
= (9cm + 15cm)×6cm/2
= 24cm×3cm
= 72 cm²

Answer:
As x→∞, f(x)→∞ is correct, also As x→−∞, f(x)→−∞.
Step-by-step explanation:
This function is a simple modification of the basic function y = x^3, which goes to infinity in Quadrant I as x increases, and to negative infinity in Quadrant II as x decreases. As x→∞, f(x)→∞ is correct, also As x→−∞, f(x)→−∞.
The same end behavior applies to f(x) = 54x^3.
ray ML and MN are perpendicular. ray MP ia an angel bisector. find the value of x .
Answer: x = 15
Step-by-step explanation:
First, we will have to acknowledge that Angle M is a complementary angle (that means that it is 90 degrees) meaning that 2x° + 4x° will equal 90 degrees. So, let’s set up this equation.
90 = 2x + 4x
90 = 6x
[tex]\frac{90}{6}[/tex] = [tex]\frac{6x}{6}[/tex]
15 = x
Therefore, the x is 15.

Raj takes a taxi to the airport. He expects the taxi to travel at an average speed of 60 mph. The distance from Raj's house to the airport is 30 miles. If Raj's taxi actually travels at an average speed of 50 mph, how many more minutes does the journey take than expected?
Answer:
6 minutes more
Step-by-step explanation:
Time = Distance ÷ Speed
Time = 30miles ÷ 60mph
Time = 30mins
Time = 30miles ÷ 50mph
Time = 36mins
36mins - 30mins = 6mins difference
Answer: 6 minutes
Step-by-step explanation:
Time = Distance / speed
When speed is 60 mph
Time = 30/60 = 1/2 hour = 30 minutes
When speed is 50 mph
Time = 30/50 = 3/5 hour = 36 minutes

For what values of the variables are the following expressions defined? 18/y
Answer:
y ≠ 0
Step-by-step explanation:
y ≠ 0
to determine a rational number, the denominator must not be zero.
The values of the variable 18/y are defined for all the values of y, such that y is the element of real numbers (R), y ≠ 0
What is a function?A function is defined as the relationship between a specific set of inputs assigned to one output each.
In order to determine if a function is defined, we need to determine the values that make the function undefined and eliminate it.
From the given information:
The value that makes 18/y undefined is any value that makes y = 0Therefore, we can conclude that 18/y is defined for all the values of y, such that y is the element of real numbers (R), y ≠ 0
