Hynes Strength Headquarters charges $40 for a sign-up fee plus $20 per month to join the gym. Orlando has paid $180 for his gym membership so far. What linear equation represents this situation?
40x + 20y = 180
y - 180 = 20(x - 40)
y = 20x + 40
x = 40y + 20
y = 40x + 20
y - 40 = 20(x - 180)
I think that it is y = 20x + 40 but I’m not sure.

suppose a population of unpaired socks is growing exponentially in a closet. At time t=0 (months) there are 4 unpaired socks at time t=4(months) there are 9 unpaired socks. How many unpaired socks will there be after 12 months?
Answer:45
Step-by-step explanation:
Given
at t=0 there are 4 unpaired socks
Suppose at any instant no of unpaired socks are [tex]N=4e^{kt}[/tex]
at t=4(months)
[tex]N=9=4e^{4k}\\e^{4k}=\frac{9}{4}[/tex]
for t=12(months)
[tex]N=4e^{12k}=4(e^{4k})^{3}[/tex]
[tex]N=4\times (\frac{9}{4})^3=\frac{9^3}{4^2}\\N=45.56\approx 45\ \text{unpaired socks}[/tex]

Your family is putting in a rectangular pool in the back yard. The pool's perimeter equals 28 feet. The contractor want the length to equal 5 more feet than 3 times the width. What will the width of your garden be?
Answer:
2.25 ft
Step-by-step explanation:
Perimter= 28ft
W= x ft
L= 3x+5
but
P=2L+2W
substitute
28=2*(3x+5)+2x
28=6x+10+2x
collet like terms
28=8x+10
28-10= 8x
18=8x
divide both sides by 8
x= 18/8
x=2.25 ft
Hence the width is 2.25 ft
A parallelogram has side lengths of 13 and 17 and an angle that measures 64°. Parallelogram W Y Z V is shown. The lengths of W V and Y Z are 13 and the lengths of W Y and V Z are 17. A diagonal is drawn from point V to point Y. The length of V Y is x. Angle V W Y is 64 degrees. Law of cosines: a2 = b2 + c2 – 2bccos(A) What is x, the length of the diagonal, to the nearest whole number? 16 18 19 21
Answer:
[tex]16\ \text{units}[/tex]
Step-by-step explanation:
[tex]WV=13\ \text{units}[/tex]
[tex]WY=17\ \text{units}[/tex]
[tex]\angle VWY=64^{\circ}[/tex]
[tex]VY=x[/tex]
From cosine rule we have
[tex]x=\sqrt{WV^2++WY^2-2WV\times WY\cos \angle VWY}\\\Rightarrow x=\sqrt{13^2+17^2-2\times 13\times 17\times \cos 64^{\circ}}\\\Rightarrow x=16.25\approx 16\ \text{units}[/tex]
Length of [tex]x[/tex] is [tex]16\ \text{units}[/tex].

Answer:
Step 2 contains error in the given problem.
Step-by-step explanation:
Given expression is:
[tex]\frac{1}{2}x-3=\frac{1}{3}x+6[/tex]
Step 1: identifying the LCM.
The LCM identified is 6.
This step is correct.
In the next step, we multiply the LCM with each term of the equation.
Step 2:
[tex]\frac{6}{1}(\frac{1}{2}x) -3 =\frac{6}{1}(\frac{1}{3}x)+6[/tex]
However,
In the given solution, the LCM is not multiplied with each term.
Hence,
Step 2 contains error in the given problem.

Charlie made a scale drawing of a house and its lot. The scale he used was 1 inch : 3 feet. The actual length of the backyard is 54 feet. How long is the yard in the drawing?
Answer:
The yard in the drawing is 18 feet long
Step-by-step explanation:
The computation of the long yars in the following is as follow:
Given that
Scale used be 1 inch : 3 feet
And, the actual length is 54 feet
So, the long it would be
= 54 feet ÷ 3 feet
= 18 feet
Hence, The yard in the drawing is 18 feet long

Six less than 2 times a number is 50. What is the number?
Answer:
a + b = 50 (Two numbers total 50)
b = a - 6 (one number is 6 less than the other)
Since we have a value, we can use the substitution metod:
a + a - 6 = 50
Simplify:
2a - 6 = 50
From here, you should know how to isolate a variable--add 6 then divide by 2 in this case. That'll give you a, and you'll be able to use that to solve for b.
2(a) -6= 50
2a-6= 50
six goes and adds to 50 on the other side
2a = 56
divide both sides by 2
a= 28
final answer 28
3(x-4)=2(-2x+1) what does x equal
Answer:
x = 2
Step-by-step explanation:
Given
3(x - 4) = 2(- 2x + 1) ← distribute parenthesis on both sides
3x - 12 = - 4x + 2 ( add 4x to both sides )
7x - 12 = 2 ( add 12 to both sides )
7x = 14 ( divide both sides by 7 )
x = 2
Answer: 2=x
Step-by-step explanation:
3(x-4)=2(-2x+1) <- multiply number outside of parentheses by numbers inside parentheses
1)3x-12=-4x+2
2)-3x -3x <- subtract -3x
-12=-7x+2 <- what you should have after
3)-2 -2 <- subtract 2
-14=-7x <- what you should have after
4)/-7 /-7 <- divide by -7
2=x <- what you should have after
/= divide
remember: negative multiplied by a negative equals a positive, and a negative multiplied by a positive equals a negative.
What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in
simplest form
Answer:
The equation of the line in the slope-intercept form will be:
y = -7xStep-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slope b is the y-interceptFrom the attached graph, taking two points
(0, 0)(-10, 70)Finding the slope between (0, 0) and (-10, 70)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:0\right),\:\left(x_2,\:y_2\right)=\left(-10,\:70\right)[/tex]
[tex]m=\frac{70-0}{-10-0}[/tex]
[tex]m=-7[/tex]
Determining the y-intercept:
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear that:
at x = 0, y = 0
Thus, the y-intercept b = 0
Now, substituting m = -7 and b = 0 in the slope-intercept form
y = mx+b
y = -7x + 0
y = -7x
Therefore, the the equation of the line in slope-intercept form will be:

3^-6 x (3^4 divided by 3^0)^2. simplfyed i need it quick im about to guess
Answer:
Step-by-step explanation:
first the parenthesis

Answer: See explanation
Step-by-step explanation:
1. 4 apples cost $1.59
1 apple would cost $1.59 ÷ 4
1.59 ÷ 4 = 0.3975
0.3975 ≈ 0.40
1 apple would cost approximately 40 cents.
2. 3 apples cost $1.00
1 apple would cost $1.00 ÷ 3
1.00 ÷ 3 = 0.3333
0.3333 ≈ 0.33
1 apple would cost approximately 33 cents.
3. Loose apples are the better buy because 1 apple costs approximately 33 cents while packaged apples cost approximately 40 cents.
4. 15 ounces cost $1.05
1 ounce would cost $1.05 ÷ 15
1.05 ÷ 15 = 0.07
1 ounce would cost 7 cents.
5. 48 ounces cost $2.39
1 ounce would cost $2.39 ÷ 48
2.39 ÷ 48 = 0.0497
0.0497 ≈ 0.05
1 ounce would approximately cost 5 cents.
6. The 48-ounce jar of applesauce is the better buy because 1 ounce costs approximately 5 cents while a 15-ounce jar of applesauce costs 7 cents.
7. 15 ounces cost $1.54
1 ounce would cost $1.54 ÷ 15
1.54 ÷ 15 = 0.1026
0.1026 ≈ 0.10
1 ounce would approximately cost 10 cents.
8. 6 (six 1 ounce) ounces cost $1.15
1 ounce would cost $1.15 ÷ 6
1.15 ÷ 6 = 0.1916
0.1916 ≈ 0.19
1 ounce would approximately cost 19 cents.
9. The larger box of raisins has a lower unit cost of 10 cents.
