Answer:
x = 6 weeks
Step-by-step explanation:
We'll let x represent the number of weeks it will take to save enough money. If she saves $11 each week, then in x weeks she will save 11x dollars.
Add this to the 107 she has already saved, and at the end of 11 weeks she will have 11x + 107 dollars.
We want the amount saved to be equal to the price of the bike, so our equation is
11x + 107 = 173
In a word problem, writing the equation is usually the hardest part. Now we solve the equation.
Subtract 107 from both sides to get
11x = 66
Divide both sides by 11 to get
x = 6 weeks

x2 + 10x + 89 = 0
what are the roots of the equation in the simplest a+bi form?
Answer:
The answer is
[tex]x = - 5 + 8 \: i \: \: \: \: or \: \: \: \: x = - 5 - 8 \: i \\ [/tex]Step-by-step explanation:
x² + 10x + 89 = 0
Using the quadratic formula
[tex]x = \frac{ - b\pm \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]From the question
a = 1 , b = 10 , c = 89
Substitute the values into the above formula and solve
We have
[tex]x = \frac{ - 10\pm \sqrt{ {10}^{2} - 4(1)(89)} }{2(1)} \\ = \frac{ - 10\pm \sqrt{100 - 356} }{2} \\ = \frac{ - 10\pm \sqrt{ - 256} }{2} \\ = \frac{10\pm 16 \: i}{2} [/tex]Separate the real and imaginary part
That's
[tex]x = - \frac{10}{2} \pm \frac{16}{2} \: i \\ x = - 5\pm8 \: i[/tex]We have the final answer as
[tex]x = - 5 + 8 \: i \: \: \: \: or \: \: \: \: x = - 5 - 8 \: i \\ [/tex]Hope this helps you

Points [tex]\frac{3}{2} , \frac{-3}{2} , 1.5 , -1.5 , 1 \frac{1}{2} , -1 \frac{1}{2}[/tex] have same absolute value as 3/2
What is an absolute value?The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign.
For example, the absolute value of 5 is 5, and the absolute value of −5 is also 5.
According to the question
numbers with an absolute value of 3/2 are
[tex]absolute value of |\frac{-3}{2}| = \frac{3}{2} \\absolute value of |1.5| = 1.5 or \frac{3}{2} \\\\absolute value of |-1.5| = 1.5 or \frac{3}{2} \\\\absolute value of |1\frac{1}{2} | = \frac{3}{2} \\\\\\[/tex]
[tex]absolute value of |-1\frac{1}{2} | = \frac{3}{2}[/tex]
Number line is attached below
Hence, Points [tex]\frac{3}{2} , \frac{-3}{2} , 1.5 , -1.5 , 1 \frac{1}{2} , -1 \frac{1}{2}[/tex] have same absolute value as 3/2 .

Yall I Need Help : Victor Has Saved $129.85 . Victor writes the equation below to help him determine x , the additional amount that he needs to save to have enough to but the bicycle . $89.25 + 129.85 = x Does Victor's equation correctly model the problem ?
I don't know what $89.25 represents in the question but I can just assume that he saved that much more. "x" represents how much more he needs.
No, he doe not represent the equation correctly. "x" should not be on the right side of the equation.
Let "y" represent the total amount of the bicycle.
The correct equation should look like:
89.25 + 129.85 + x = y

The function h (x) = StartFraction 1 Over x squared + 1 EndFraction is the result of the composition f(g(x)). If g(x) = x2 + 1, what is f(x)? f (x) = StartFraction 1 Over StartRoot x EndRoot f (x) = StartFraction 1 Over x + 1 EndFraction f (x) = StartFraction 1 Over x squared + 1 EndFraction
Answer:
f(x) = 1/x
Step-by-step explanation:
Given h(x) = 1/(x²+ 1) and g(x) = x²+ 1. If h(x) = f(g(x)) then;
1/(x²+ 1) = f(x²+ 1)
f(x²+ 1) = 1/(x²+ 1)
This means that function of (x²+ 1) will give 1/(x²+ 1). To get f(x), we will simply replace x²+ 1 in the function f(x²+ 1) with x to give;
f(x) = 1/x
Hence the function of x i.e f(x) is 1/x

3,6 reflected across the line y=3
Answer:
(3, 0)
Step-by-step explanation:
(3,6) reflected across the line y=3
y = 3 is parallel to x- axis, the x-coordinate doesn't change and y-coordinate reflects as y - 2*3
(x, y) → (x',y') = (x, y -2*3)(3, 6) → (3, 6 -6) = (3, 0)Answer is (3,0)
If f(x) =5x, what is f(6)
Answer:

The mean and standard deviation of a normal distribution are 150 and 12 respectively. What percentage of values lie between:
a) 138 and 162
b) 126 and 174
c) 126 and 162
d) 162 and 174
Answer:
Step-by-step explanation:
Use a calculator with built-in statistical functions. The function applying here is normcdf(, the "cumulative density function."
(a) The percentage of values lying between 138 and 162 is
norm(138,162, 150, 12), which comes out to 0.683, or 68.3%.
(b) Find norm(126, 174, 150,12): 0.945, or 94.5%
(c) Find norm(126,162, 150,12); 0.819, or 81.9%
(d) Find norm(162, 174,150,12): 0.136, or 13.6%

Cynthia wants to buy a rug for a room that is 18ft wide and 26ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 240 square feet of carpeting. What dimensions should the rug have?
The room is 18 ft by 26 ft which is 468 ft^2
She can afford a 240 ft^2 rug
12 * 20 = 240
She can afford a rug that is 12 ft wide by 20 ft long
The dimensions that the rug she wants to buy should have is: 12 ft by 240 ft
How to find the area of the rectangle?The formula for the area of a rectangle is expressed as:
Area = length * Width
Now, we are told that:
Dimensions of room = 18 ft by 26 ft
If she leaves a strip of 3ft across the room, then, we can say that area that needs carpeting = 12 ft by 20 ft
Let us check with the 240 square feet of carpeting
12 * 20 = 240 ft
