Answer:
x = -3y - 3
Step-by-step explanation:
x + 3y = -3
Subtract 3y from both sides;
x = -3y - 3

how many years to double investment if interest rate is .10%
Answer:
How the Rule of 72 Works. For example, the Rule of 72 states that $1 invested at an annual fixed interest rate of 10% would take 7.2 years ((72/10) = 7.2) to grow to $2. In reality, a 10% investment will take 7.3 years to double ((1.107.3 = 2). The Rule of 72 is reasonably accurate for low rates of return.
Step-by-step explanation:
For example, if you invest $10,000 at 10 percent compound interest, then the “Rule of 72” states that in 7.2 years you will have $20,000. You divide 72 by 10 percent to get the time it takes for your money to double. The “Rule of 72” is a rule of thumb that gives approximate results

Water World charges customers $50 per day to rent a canoe and $25 as a nonrefundable insurance fee.
Which function represents the total cost, y, of renting a canoe for x days at Water World?
Answer:
y=50x+25
The x days would multiply by 50 and adding 25 to 50x to get y.
A clothing manufacturer uses the model a=f+4−−−−√−36−f−−−−−√ to estimate the amount of fabric to order from a mill. In the formula, a is the number of apparel items (in hundreds) and f is the number of units of fabric needed. If 4 apparel items will be manufactured, how many units of fabric should be ordered?
Questions:
A clothing manufacturer uses the model a = √(f + 4) - √(36 - f) to estimate the amount of fabric to order from a mill. In the formula, a is the number of apparel items (in hundreds) and f is the number of units of fabric needed. If 400 apparel items will be manufactured , how many units of fabric should be ordered?
Answer:
32 units of fabrics
Step-by-step explanation:
Given
[tex]a = \sqrt{f + 4} - \sqrt{36 - f}[/tex]
Required
Find f when a = 4
Substitute 4 for a
[tex]4 = \sqrt{f + 4} - \sqrt{36 - f}[/tex]
Rewrite as:
[tex]\sqrt{36 - f} + 4 = \sqrt{f + 4}[/tex]
Square both sides
[tex](\sqrt{36 - f} + 4)^2 = (\sqrt{f + 4})^2[/tex]
[tex](\sqrt{36 - f} + 4)^2 = f + 4[/tex]
[tex]36 - f + 8\sqrt{36 - f} + 16 = f + 4[/tex]
Collect Like Terms
[tex]8\sqrt{36 - f}= f +f+ 4 - 36 -16[/tex]
[tex]8\sqrt{36 - f}= 2f -48[/tex]
Divide through by 2
[tex]4\sqrt{36 - f}= f -24[/tex]
Square both sides
[tex]16(36-f) = (f - 24)^2[/tex]
[tex]16(36-f) = f^2 - 48f + 576[/tex]
[tex]576-16f = f^2 - 48f + 576[/tex]
[tex]-16f = f^2 - 48f[/tex]
Collect like terms
[tex]f^2 - 48f + 16f = 0[/tex]
[tex]f^2 -32f = 0[/tex]
Factorize
[tex]f(f - 32) = 0[/tex]
[tex]f = 0[/tex] or [tex]f = 32[/tex]
f can not be 0 because some units must be ordered.
So, f = 32

Answer:
y = 5/3x + 20/3
Step-by-step explanation:
Points on the graph: ( -4, 0) and (1, -5)
Slope:
m=(y2-y1)/(x2-x1)
m=(-5-0)/(1-4)
m=(-5)/(-3)
m=5/3

i need help to find m<k
Answer:
angle k = 72
Step-by-step explanation:
Hey There!
When triangles are similar all of the angles that correspond with each other are congruent ( have the same value)
ex. angle g and angle m are corresponding so they both equal 70
So to find angle K we have to find the value of angle F (because they are corresponding)
So we are given two angles
remember that all angles in a triangle will add up to equal 180
so we subtract the given angles from 180 to find the missing angle
180-38-70=72
so angle F = 72
like stated earlier angle F and angle K are corresponding so if angle F equals 72 then Angle K = 72

The measure of the angle ∠JKL is 230°, the area of the shaded and unshaded region is (230/18) × 5π and (325/9) × π. Then statements 1 and 3 are true and statement 2 is false.
What is a circle?It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
The figure is given.
Radius (r) = 10 units
Then the sum of the angle should be 360 degrees for a circle. Then
130° + ∠JKL = 360°
∠JKL = 230°
The area of the shaded region will be
[tex]\rm Shaded \ area = \dfrac{230}{360}\times \pi 10^2\\\\Shaded \ area = \dfrac{230}{360}\times \pi 100\\\\Shaded \ area = \dfrac{230}{18}\times 5\pi \\[/tex]
Then the area of the unshaded region will be
[tex]\rm Unshaded \ area = \dfrac{130}{360}\times \pi 10^2\\\\Unshaded \ area = \dfrac{130}{360}\times \pi 100\\\\Unshaded \ area = \dfrac{325}{9}\times \pi \\[/tex]

These are the options for all three: 5/13, 12/5, 12/13, 5/12, 13/5, 13/12.
Answer:
sin x = 36/39 = 12/13cos x =15/39 = 5/13tan x = 36/15 = 12/5In this triangle,
Base ( B ) = 15 Hypothenuse ( H ) = 39 Perpendicular ( P ) = 36Find :-sin x = ?
cos x = ?
tan x = ?
Solution :-sin x = Perpendicular / Hypothenuse
= 36 / 39 = 12 /13
cos x = Base / Hypothenuse
= 15 / 39 = 5/13
tan x = Perpendicular / Base
= 36 /15 = 12 / 5
The length of a rectangle is 7 centimeters greater than the width.
The perimeter is 54 centimeters. Find the length and width.
Answer:
length = 17cm, width = 10cm
Step-by-step explanation:
2L + 2w = 54
L = w + 7
Substitute:
2(w + 7) + 2w = 54
2w + 14 + 2w = 54
4w = 40
w = 10
L = 10 + 7 = 17

PLEASE HELPP Find the value of x. Assume that segments that appear to be tangent are tangent. Round your answer to the nearest tenth.
The value of x assuming e that segments that appear to be tangent are tangent is 8
Circle geometryThe triangle inside the circle is right angles since the side length "x" is tangential to the circle.
To determine the value of "x", we will use the Pythagorean theorem as shown:
17^2 = x^2 + 15^2
289 = x^2 - 225
x^2 = 289 - 225
x^2 = 64
x = 8
Hence the value of x assuming e that segments that appear to be tangent are tangent is 8

Which ordered pair is a solution to the graphed inequality?
Given:
The graph of a system of inequalities.
To find:
The ordered pair which is a solution to the graphed inequality.
Solution:
The boundary lines are:
[tex]x-2y=4[/tex]
[tex]2x-y=4[/tex]
From the given graph it is clear that only point (3,1) lies in the shaded region.
Points (2,-1) and (4,0) lie on the boundary line [tex]x-2y=4[/tex] but the boundary line is dotted. It means the points on the line are not in the solution set.
point (0,-1) does not belong to the shaded region.
Therefore, the correct option is A.

Jerry wants to buy 4 Michelin tires. Each tire costs $213.99. Calculate his total price if the tax rate is 7.25%.
Answer:
$918.02
Step-by-step explanation:
As each tire costs $213.99, you will be multiplying that by 4:
$213.99*4 = $855.96
Now you will have to add the tax to the price. You will do the following:
$855.96*.0725 = 62.0571
You will round that to $62.06
$855.96+$62.06
The total would be $918.02
