Identify the points which of the following coordinate pairs make the equation x - 9y = 12 true?
Show your reasoning.
1. ( 12, 0 )
2. ( 0, 12 )
3. ( 3, -1 )
4. ( 0, - 4/3 )
Answer:
Step-by-step explanation:
Because in equation x-9y=12
If we put x=12 and y=0 then it satisfy equation. (12)-9(0)=12
So, (12,0) make equation
(3,-1) also make equation
(3)-9(-1)=12
(0,-4/3) also make equation
Because
0-9(-4/3)=12
Only (0,12) is not making
Beacuse
(0)-9(12) is not equal to 12

Answer:
Step-by-step explanation:
Triangles EFG and FGH are similar.
x/15 = 36/39
x/15 = 12/13
x = 15*12/13 = 180/13 ≈ 13.8 units
The required measure of x is given as 5.8 in the given triangle.
The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.
What are similar triangles?Similar triangles are triangle that has a relationship as of some scale factor.
here,
From the figure,
From triangle GHF and triangle EGF
x / 15 = 15 / 39
x = 225 / 39
x = 5.8
Thus, the required measure of x is given as 5.8 in the given triangle.

(-12b - 6 + 9b - 18) equivalent to 2(b + 8)? Show your work.(please help)
Answer:
Well, -1-126 (-12b - 6 + 9b - 18) equals 378b + 2023.
Step-by-step explanation:
Subtract numbers:
−1−126 (−12−6+9−18)
−1−126 (−12−24+9)
Combine like terms:

Answer:
1.The formula to convert Celsius to Fahrenheit is:
F = 1.8 C + 32
Multiply the Celsius temperature by 1.8.
Add 32 to this number.
Report the answer in degrees Fahrenheit.
Example: Convert 20°C to Fahrenheit.
F = 1.8 C + 32
F = 1.8 (20) + 32
1.8 x 20 = 36 so F = 36 + 32
36 + 32 = 68 so F = 68°F
20°C = 68°F

Answer:
C
Step-by-step explanation:
Remark
The easiest way to do this is to add the two givens together and then multiply by two. Why 2? Because the formula is P = 2(L + W)
Givens
L = 8x - 2
W = 4x - 4
Solution
P = 2*(8x - 2 + 4x - 4)
P = 2*(12x - 6)
P = 24x - 12

Original Price: $85, Sale Price: $51, Discount =
what is the discount? (tell me how you got your answer)
Answer:
the discount is 43.35 or the final price $7.65
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 51 × 85/100
Discount = 51 x 0.85
You save = $43.35
Final Price = Original Price - Discount
Final Price = 51 - 43.35
Final Price = $7.65
