Answer: X < -3
Step-by-step explanation:
-15x - 3 > 42
-15x - 3 + 3 > 42 + 3
-15x > 45
-15x/-15 > 45/-15
Since we are dividing by a negative, we flip the >
x < -3
So, let's check
-4 < -3
-15*-4 - 3 > 42
60 - 3 > 42
57 > 42
Now, let's see if -3 will work.
-15*-3 - 3 > 42
45 - 3 > 42
42 > 42 (False)
Okay, now let's try 4
-15*4 - 3 > 42
-60 - 3 > 42
-63 > 42
This is false, so it is x < -3
The correct answer is x < -3
Explanation:
To solve our equation we first need to set out our equation, -15x – 3 > 42. Next, we add 3 to both sides of our equation, -15x - 3 + 3 > 42 + 3 = -15x > 45. Then, we multiply both sides by -1(Or in other words, reverse the inequality), -15x * -1 > 45 * -1 = 15x < -45. And then, we divide both sides by 15, 15x/15 < -45/15 = x < -3. Finally, we have our answer of x < -3.

I have the data in that picture , I need help answering these questions that continue with that
F: how much money will Jason have in the bank after 9 weeks
G: if Jason has $80 left, how many weeks have passed
This is for question 2 in the picture
Answer:
F $185
G 12 weeks
Step-by-step explanation:
Assuming your equation is correct
y = -35x +500
We want to let x=9
y = -35(9) +500
y = -315+500
y =185
Jason will have $185 after 9 weeks
If he has 80 dollars left we put that in for y and solve for x
80 = -35x +500
Subtract 500 from each side
80-500 = -35x +500-500
-420 = -35x
Divide each side by -35
-420/-35 = -35x/-35
12 = x
After 12 weeks he will have 80 dollars left
15. You are buying batteries, a stereo, and some CDs from the I.B. Electronics store. You can buy from this store online or in a physical store. You have a coupon for 10% off that can only be used in the physical store and a $5.00 off coupon that can only be used online. The sales tax of 5% only applies to the physical store. Shipping for the online store is a flat rate of $6.99. You are trying to decide whether to shop at the physical store or the online store. Using the pricing information below, how much would you pay at the physical store after all discounts, taxes, and shipping fees have been applied?
The total amount you would pay at the physical store after all discounts, taxes, and fees have been applied is [tex]{128.36} \)[/tex].
Let's go through the calculations again to find the final cost at the physical store after all discounts, taxes, and fees.
Physical Store Pricing:
- Batteries: 2 packs at $5.99/pack
- Stereo: 1 system at $100.00
- CDs: 3 CDs at $7.95 each
Discounts and Taxes in the Physical Store:
1. 10% Off Coupon: This coupon applies to the total purchase amount before tax.
2. Sales Tax: 5% sales tax applies to the total purchase amount after applying discounts.
Calculation Steps:
Step 1: Calculate the total cost of items before discounts and tax:
- Batteries: 2 packs × $5.99/pack = $11.98
- Stereo: $100.00
- CDs: 3 CDs × $7.95/CD = $23.85
Total before discounts: $11.98 + $100.00 + $23.85 = $135.83
Step 2: Apply the 10% off coupon:
- 10% of $135.83 = $13.583
- Total after 10% off: $135.83 - $13.583 = $122.247
Rounded to two decimal places: $122.25
Step 3: Apply the 5% sales tax:
- 5% sales tax on $122.25:
[tex]\[0.05 \times 122.25 = 6.1125\][/tex]
Rounded to two decimal places: $6.11
Step 4: Calculate the final cost at the physical store:
- Total cost after tax: $122.25 + $6.11 = $128.36
The complete question is

Explain how to determine if the two expressions are equivalent using x = 6 and x = 10.
8x + 40 8(x + 5)
The expressions 8x + 40 and 8(x + 5) are equivalent because both expressions have the same value at x = 6 and x = 10
How to determine the two equivalent expressions?The expressions are given as:
8x + 40 and 8(x + 5)
When x = 6, we have:
8x + 40 = 8 * 6 + 40
8x + 40 = 88
8(x + 5) = 8(6 + 5)
8(x + 5) = 88
When x = 10, we have:
8x + 40 = 8 * 10 + 40
8x + 40 = 120
8(x + 5) = 8(10 + 5)
8(x + 5) = 120
Notice that both expressions have the same value at x = 6 and x = 10
Hence, the expressions 8x + 40 and 8(x + 5) are equivalent

b. Bernie has $7.00.
c. Chrissy has $6.50.
d. Dina has $6.00.
e. Evan has $5.00.
f. Frank has $14.00.
Who has enough money to go to the movie? ( write names below )
Answer:
Bernie, Chrissy, Dina and Frank
Step-by-step explanation:
if all 73 tickers are sold, the theatre makes $438 so each ticket is worth $438/73
this equals to $6.00 for one ticket
this means that Bernie, Chrissy, Dina and Frank have enough money to see the movie
Answer:
Bernie, Chrissy, Dina, and Frank are able to go.
Step-by-step explanation:
The question is not entirely clear. I take it that 73 tickets will bring in 438 dollars. If that is so, each ticket is selling for the solution of this proportion.
x / 1 = 438/73 Just do the division on the right
x = 6.00 dollars.
So Amanda will not be able to go.
Even will not be able to go.

what is the inverse of the function x + 2y + 3 = 0
The inverse of the function x + 2y + 3 = 0 is found by first expressing the function explicitly as y = -½x - 1½ and then swapping x and y to solve for the new y, yielding the inverse function y = -2x - 3.
Explanation:To find the inverse of a function, we typically swap the roles of x and y, and then solve for y. Given the function x + 2y + 3 = 0, we first write the function explicitly as y in terms of x:
y = -½x - ³2
Now let's find the inverse:
Swap x and y to get x = -½y - ³2.Solve for y. Multiply every term by 2 to get rid of the fraction: 2x = -y - 3.Rearrange the equation to solve for y: y = -2x - 3.This new function y = -2x - 3 is the inverse of the original function.

The height y (in feet) of a toss in bocce ball can be modeled by y=-x^2+4x, where x is the horizontal distance (in feet)
Interpret the x-intercepts of the graph of the equation.
How far does the bocce ball land on the ground?
The x-intercepts of the equation represent the points where the height of the toss is equal to 0. The bocce ball lands on the ground at a horizontal distance of 0 feet and 4 feet.
Explanation:The x-intercepts of the graph of the equation represent the points where the height of the toss is equal to 0.
In other words, these points represent the horizontal distance where the bocce ball lands on the ground.
o find the x-intercepts, we set y=0 and solve the equation:
0=-x^2+4x
x(x-4)=0
Therefore, the x-intercepts are x=0 and x=4.
This means that the bocce ball lands on the ground at a horizontal distance of 0 feet and 4 feet.
What is the equation of the line with a slope of -2 that passes through the
point (4, -3)?
y + 3 = 4(x - (-2))
y + 4 = -2(x - 3)
y + 3 = -2(x - 4)
y + 4 = 3(x - (-2))
The point-slope form of the line:
[tex]y-y_1=m(x-x_1)[/tex]
We have the slope m = -2 and the point (4, -3). Substitute:
[tex]y-(-3)=-2(x-4)\\\\\boxed{y+3=-2(x-4)}[/tex]

Amanda is riding her bicycle. She takes 5 hours to ride 62.5 kilometers. What is her speed?
Answer:
12.5 per kilometers
Step-by-step explanation:
to find speed is going to be distance divided by time so 62.5/5
so her speed is going to be 12.5
Amanda's average speed while riding her bicycle is found by dividing the total distance of 62.5 kilometers by the total time of 5 hours, resulting in an average speed of 12.5 kilometers per hour.
To calculate her speed, we use the formula for speed, which is speed = distance ÷ time. Applying the given values, we have speed = 62.5 kilometers ÷ 5 hours.
Therefore, Amanda's average speed is 12.5 kilometers per hour. This calculation involves dividing the total distance traveled by the total time taken, resulting in the average speed over the journey.
Make (X-12)/(x-8) equal to zero

Answer:
x=12 makes (X-12)/(x-8) equal to zero
x=8 makes (X-12)/(x-8) undefined
Step-by-step explanation:
(x-12)/(x-8) = 0
The first step is to multiply each side by x-8
(x-8) *(x-12)/(x-8) = 0 * (x-8)
This cancels the denominator. x≠ 8 because the denominator would equal 0 and then it becomes undefined.
x-12 = 0
Add 12 to each side

I bought 4 hamburgers and 3 fries for $14.25 and the next day I bought 3 hamburgers and 5 fries for $15.50 find out the price for each hamburger and fry
Answer:
The cost of a hamburger is 2.25
The cost of fries is 1.75
Step-by-step explanation:
Let h = cost of hamburgers
let f= cost of fries
4h + 3f = 14.25
3h+5f = 15.50
I will solve these by elimination
Multiply the 1st equation by 3
3(4h + 3f )= (14.25)3
12h +9f = 42.75
Multiply the 2nd equation by -4
-4(3h+5f )= -4(15.50)
-12h - 20f = -62
Add the modified equations together
12h +9f = 42.75
-12h - 20f = -62
----------------------------
-11 f = -19.25
Divide each side by -11
-11f/-11 = -19.25/-11
f = 1.75
Now we need to find the cost of the hamburger
3h+5f = 15.50
Substitute the cost of the fries in
3h + 5(1.75) = 15.50
3h +8.75 + 15.50
Subtract 8.75 from each side
3h = 15.5-8.75
3h =6.75
Divide by 3
3h/3 =6.75/3
h = 2.25
The rule at Anna's house is that if she eats all of her vegetables and does all of her does each day, she earns 2 hours of Internet time which she can save. Anna started her week with 3 hours saved. If she eats all of her vegetables and does all of her chores each day for 4 days straight how many hours does she have after the four days she uses 6 hours of her internet time
Answer:
5 Hours
Step-by-step explanation:
Given :- 2 hours can be earned each day if she eats all of her vegetables and does all of her chores.
Saved hours at the start of the week = 3 hours
Hours earned in 4 days = 2 hours × 4
= 8 hours
Hours used in 4 days = 6 hours
Hours left after 4 days = Saved hours at the start of the week + Hours earned in 4 days - Hours used in 4 days
Hours left after 4 days = 3 + 8 - 6
= 5 hours
A kite is stuck in a 36-ft tree. If the angle of elevation from the kite and the ground is 12, find the length of the kite.
Answer:
173.15 ft.
Step-by-step explanation:
Please find the attachment.
Let L be the length of kite.
We have been given that a kite is stuck in 36-ft tree. The angle of elevation from the kite and the ground is 12.
We can see from our attachment that kite and tree form a right triangle. height of tree is opposite of angle of elevation and length of kite is hypotenuse.
Since we know that Sine relates the opposite and hypotenuse of a right triangle, so we will use sine to find the length of kite.
[tex]sin(12)=\frac{36}{L}[/tex]
[tex]L=\frac{36}{sin(12)}[/tex]
[tex]L=\frac{36}{0.207911690818}[/tex]
[tex]L=173.1504364105882792\approx 173.15[/tex]
Therefore, the length of kite is 173.15 ft.
