8. Write the standard form of the equation y + 4 = - 12 (x – 1).
Answer:
12x + y = 16
Step-by-step explanation:
Standard Form: Ax + By = C
Step 1: Write point-slope form
y + 4 = -12(x - 1)
Step 2: Find slope-intercept form
y + 4 = -12x + 12
y = -12x + 16
Step 3: Find standard form
12x + y = 16

D is between C and E. CE = 6x, CD = 4x + 8, and DE = 28. Find CE.
Please Answer ASAP!!!
(BTW it's high school geometry)
Answer:
CE=108
Step-by-step explanation:
*I don't have my phone with me so I can't add a picture of what I drew*
First, draw a line. On one end, write C. On the other end, write E. In the middle of them, write D. The question states that CE=6x, so on the bottom of the line, write 6x. On top on the first half write 4x+8 (between C and D). On the other half between D and E write 28.
According the the information we have been given and the diagram we made, CD+DE=CE. Hence, (4x+8)+28=6x
(4x+8)+28=6x (subtract four from both sides)
8+28=6x-4x (combine like terms)
36=2x (divide two from both sides)
x=18
Now, substitute 18 for x in 6x (CE=6x)
CE=6(18)
CE=108

Step-by-step explanation:
determine the effects on the graph of the parent function f(x)=x+10 when g(x)=0.3f(x)
Answer:
First, remember the definition of a vertical contraction/dilation.
If we have a function f(x), and we dilate it with a factor A, such as:
g(x) = A*f(x).
If A is larger than 1, then we are dilating the graph of f(x)
if A is smaller than 1, then we are contracting the graph of f(x).
In this case we have:
f(x) = x + 10 and g(x) = 0.3*f(x) = 0.3*x + 0.3*10 = 0.3*x + 3.
A = 0.3
then we have a contraction.
From this, we can conclude that the effects of this transformation in the graph will be that the graph of g(x) will be a vertical contraction of the graph of f(x).
(Where contracting means that in a given interval [x1, x2] the associated interval [f(x1), f(x2)] will be larger than [g(x1), g(x2)])
Below you can see both graphs, and see the difference between them, where green is f(x) and blue is g(x)
In the given figure QR ∥AB, RP∥ BD,CQ=x+2,QA=x,CP=5x+4,PD=3x.The value of x is
Answer:
by BPT it will be solved
Step-by-step explanation:
CQ/QA=CP/PD
x+2/x=5x+4/3x
by cross multiplication
answer will be 1
Parallel sides are sides that are equidistant from one another. The value of x is 1
Given that:
[tex]CQ = x + 2\\QA = x\\CP = 5x + 4\\PD = 3x[/tex]
Since:
QR & AB are parallel, and RP & BD are parallel.
Then by theorem of similarities:
[tex]\frac{CQ}{QA} = \frac{CP}{PD}[/tex]
This gives:
[tex]\frac{x+2}{x} = \frac{5x + 4}{3x}[/tex]
Multiply both sides by 3x
[tex]3x \times \frac{x+2}{x} = \frac{5x + 4}{3x} \times 3x[/tex]
[tex]3 \times (x+2) = 5x + 4[/tex]
Open bracket
[tex]3x+6 = 5x + 4[/tex]
Collect like terms
[tex]5x - 3x = 6 -4[/tex]
[tex]2x = 2[/tex]
Divide both sides by 2
[tex]x = 1[/tex]

5x - 3(x + 9) + 10 = 4
Answer:
[tex]x = \frac{21}{2}[/tex]
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x − 3(x+9) + 10 = 4
5x + (−3)(x) + (−3)(9) + 10 = 4 (Distribute)
5x + −3x + −27 + 10 = 4
(5x+−3x) + (−27+10) = 4 (Combine Like Terms)
2x + −17 = 4
2x − 17 = 4
Step 2: Add 17 to both sides.
2x − 17 + 17 = 4 + 17
2x = 21
Step 3: Divide both sides by 2.
[tex]\frac{2x}{2} = \frac{21}{2}[/tex]
[tex]x =\frac{21}{2}[/tex]

2. The floor plan for a rectangular building states that the length of the building is to be 8 meters more than 3 times its width . If the floor area is to be 256 square meters, what must be the length and width of the building?
Area of a rectangle = Length × Width
Length of the building is to be 8 meters more than times its width.
= Length = 3W + 8
Area = 256m²
Hence:
256 =( 3W + 8 )× W
256 = 3W² + 8W
= 3W² + 8W - 256
Factorise
= 3W(W - 8) + 32(W - 8)
= (3W + 32) ( W - 8)
W - 8 = 0
W = Width = 8m
Length = 3W + 8
Length = 3(8) + 8
= 24 + 8
= 32m.
D. 32 meters long and 8 meters wide
3. The area of the dining room is 130 square units. If the width is 3 meter less than its length what is the width
of the room?
A. 10 units
B. 11 units
C 12 units
D. 13 units
Area = Length × Width
The width is 3 meter less than its length
W = L - 3
Area = 130 square units
Hence:
130 = L (L - 3)
130 = L² - 3L
L² - 3L - 130
= L² + 10L - 13L - 130
= L(L + 10) - 13(L + 10)
= (L - 13) (L + 10)
L - 13 = 0
L = Length = 13 units
L + 10 = 0
L = -10 units.
W = L - 3
L = 13 units
W = 13 - 3
W = 10 units
Therefore, the width of the room is 10 units
A. 10 units
4. One of the factors of 2b² + 15b-50 is b + 10. What is the other factor?
A.2b - 10
B. 2b -5
C. 2b +5
D. 2b + 10
2b² + 15b -50
One of the factors is b +10.
We factorise
2b² + 15b - 50
= 2b² + 20b - 5b - 50
= 2b(b + 10) - 5(b + 10)
= (2b - 5) (b + 10)
The other factor is 2b - 5
B. 2b -5
5. The area of the nachos is 15x² - 10x square centimeters. If the base is 5x centimeters, which is the length of

A. 3x - 2 cm.
B. 3x + 2 cm
C. 6x-4 cm
D. 6x + 4 cm
Nachos are triangular in shape
Area of a triangle = 1/2 × Base × height
A = 1/2 bh
A = bh/2
2A = bh
h = 2A/b
The area of the nachos is 15x - 10x square centimeters. If the base is 5x centimeters,
h = 2(15x² - 10x)/5x
h = 30x² - 20x/5x
h = 30x²/5x - 20x/5x
= 6x - 4 cm
the length of the height is:
C. 6x - 4 cm
