Answer: x= 18.2
Step-by-step explanation:
We can assume that this is a right triangle meaning it is 90 degrees, so
2x-1 + 3x must = to 90 degrees which gives us,
2x-1+3x= 90 => 2x+3x-1=90 (Rearrange like terms) => 5x-1=90 => 5x=91 => x= 18.2
The function f(x)=ln(9.2x) is a horizontal compression of the parent function by a factor of 1/9.2
Step-by-step explanation:
The multiplication of a function by a number compresses or stretches the function vertically while to compress or stretch the function horizontally, the input variable is multiplied with a number.
i.e.

where b is a constant.
Now
If b>0 then the function is compressed horizontally
The given function is:

As the variable in function is multiplied with a number greater than zero, the function will stretch horizontally.
The function f(x)=ln(9.2x) is a horizontal compression of the parent function by a factor of 1/9.2

Answer:
<h3>
a₁₈ = 10</h3>
Step-by-step explanation:
aₙ₊₁ = aₙ + d
a₁₉ = a₁₈ + d
- 7 = a₁₈ + (-17)
a₁₈ = - 7 +17
a₁₈ = 10
62/75 = 0.82666666666 * 100 = 82.6 recurring percent.
Almons:walnuts:rasins=1:2:3
x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute
12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins
1/3 pound walnuts
2/3 pound almonds
1 pound rasins
