Answer:
that graph will feature an area delimited by a line of slope m passing through the origin (0,0). Since m>0 the slope is positive, meaning the line goes up. Since the equation is y > mx, the inequality sign being >, that means the area represented will be ABOVE the line drawn.

solve the equation (X-1) (2x+5)=0
Answer:
x = -5/2
x = 1
Step-by-step explanation:
(x-1) (2x+5) = 0
Divide both sides by (x-1)
2x+5 = 0
Subtract 5 on both sides.
2x = -5
Divide 2 into both sides.
x = -5/2
(x-1) (2x+5) = 0
Divide both sides by (2x+5).
x - 1 = 0
Add 1 to both sides.
x = 1

The function g(x) is a transformation of f(x), and g(x) = f(x) + 2. What type of transformation of f(x) is g(x)? A. dilation B. horizontal translation C. reflection D. vertical translation
Answer:
This is called a vertical translation, which is answer D.
Step-by-step explanation:
Given: g(x) = f(x) + 2.
This means that g(x) is the "same" like (x) and that all points of the graph of f(x) are shifted up by 2 units, in order to form g(x).
The type of transformation is called a vertical translation, which is answer D.
Please answer this thanks
Answer:
36 units
Step-by-step explanation:
One leg of the triangle is 9 and the other is 12. Now you use the pythagorean theorem to solve for the last side of the the triangle. The pythagorean theorem is a^2+b^2=c^2. a and b are 9 and 12. It doesn't matter which order because of the commutative property. You know which ones are a and b because they are the shorter sides.
Now you plug it into the equation. 9^2+12^2=c^2. this simplifies to 81+144=c^2. Now you combine like terms and get c^2=225. You square root both sides now and get c=15. The longest side is 15. Now you add all of them together to find the perimeter. 9+12+15= 36
First identify the angle RELATIONSHIP, then find the measure of the angle indicated in bold.
Answer:
Same-side interior angles
m∠ = 110°
Step-by-step explanation:
Step 1: Set up equation
6x + 16 + 13x - 7 = 180
Step 2: Combine like terms
19x + 9 = 180
Step 3: Isolate x and solve
19x = 171
x = 9
13(9) - 7 = 110°

the option for if PQRS is a quadrilateral inscribed in a circle, then the opposite angles of the quadrilateral are complementary/supplementary/equal
Answer:supplementary
Step-by-step explanation:
Opposite angles in any quadrilateral inscribed in a circle are supplements of each other.
If a quadrilateral is inscribed in a circle, opposite angles are congruent.
The values of x and y are 98 and 112 degrees respectively.
How to find the angles of a quadrilateral?
When a quadrilateral is inscribed in a circle, opposite angles are supplementary angles.
Therefore, the angles of the cyclic quadrilateral are as follows:
x + 82 = 180
x = 180 - 82
x = 98 degrees.
y + 68 = 180
y = 180 - 68
y = 112 degrees.

ABC is a straight line.
The length of BC is three times the length of AB.
AC = 80 metres.
Work out the length BC.
Answer:
AB = 20 metres
BC = 60 metres
Step-by-step explanation:
Let AB = x
Then, BC = 3x
Condition:
=> x+3x = 80
=> 4x = 80
Dividing both sides by 4
=> x = 20
So,
AB = 20 metres
BC = 3(20)
BC = 60 metres

x^2+6x+4 Which of the following is equivalent to the expression above? Justify your answer. A) (x+3)^2+5 B) (x+3)^2-5 C) (x-3)^2+5 D) (x-3)^2-5
Answer:
B) ( x+3)² - 5
Step-by-step explanation:
Given expression
x²+6x+4
Adding '9' and subtracting '9' of given expression
⇒ x² + 2 (3) (x) +(3)² -(3)² +4
(a + b)² = a² + 2 a b + b²
⇒ ( x+3)² - 9 +4
⇒ ( x+3)² -5
Triangle ABC is dilated about the origin by a factor of 2, reflected in the x-axis, rotated 180°, and translated 2 units to the right and 4 units down to form triangle XYZ. Which statement is true? a. The two triangles are congruent because the each transformation is a rigid motion. b. The two triangles are not congruent because the orientation is changed. c. The two triangles are congruent because the orientation did not change. d. The two triangles are not congruent because dilation is not a rigid motion.
Answer:
d. The two triangles are not congruent because dilation is not a rigid motion.
Step-by-step explanation:
Triangle ABC is dilated about the origin b a factor of 2. It is then reflected and translated to form Triangle XYZ.
The new triangle formed is not congruent to ABC because the image is not the same size as the pre-image. It is only rigid transformations that preserve length, however dilation is not a rigid transformation.
A lighthouse has a shadow that is 36 feet long. Zara is 4 feet tall, and she is standing next to the lighthouse. Zara has a shadow that is 3 feet long. Use this information to complete the statement about the lighthouse
Answer:
48 feet
Step-by-step explanation:
At a particular time, objects and their shadows are proportionate.
Therefore, in figure,
AB/FD = BC/DE --- (1)
where AB is the height of the lighthouse, BC, its shadow and FD is the height of Zara and DE is her shadow.
From the given information,
BC = 36 feet
FD = 4 feet and DE = 3 feet
(1) becomes
AB/4 = 36/3
AB = 12
AB = 48
Hence, the height of the lighthouse is 48 feet.

Suzan bought some balloons and repacked them for sale. He threw away 76 balloons each. Each packet was sold at $86. After selling all the packet of balloon he collected $9,632 altogether. How many balloons did Suzan buy? A.1,644 B.1,464 C.1,466 D.1,646
Answer:
188 balloons
Step-by-step explanation:
First, we have to divide the amount he collected altogether by the price of each balloon that he sold to find out how many balloons he sold:
9632 / 86 = 112 balloons
She sold 112 balloons.
We know that she threw 76 balloons away, therefore, the number of balloons she bought was:
112 + 76 = 188 balloons
