200 = 8x + 40
Rearrange,
x = 160/8 = 20
He would need to save $20 a week
200= 20 × 8 + 40
Answer:
8x + 40 ≥ 200At least $20 each weekStep-by-step explanation:
Target amount = at least $200Jason already has = $40Time = 8 weeksSaved amount each week = xRequired inequality:
8x + 40 ≥ 2008x ≥ 160x ≥ 160/8x ≥ $20Find the inverse for this relation: { (1, -3), (-2, 3), (5, 1), (6, 4) }
Answer:
(-3,1), (3,-2), (1,5), (4,6)
Step-by-step explanation:
For finding and inverse of a relationship, you simply just need to swap the x and y values. So the x will go into the y value and the y value will go into the x value.
The inverse relation for the given relation is {(-3, 1), (3, -2), (5, 1), (6, 4)}.
What is relation?A relation in mathematics can be defined as a set of a pair of elements belonging to each set. It is also called as a mapping from one set to the other.
The given relation is { (1, -3), (-2, 3), (5, 1), (6, 4) }.
The domain of the given relation is set of all the first elements of each pair and the range is the set of all the second elements of each pair.
The range and domain set can be written as,
Domain = {1 , -2, 5, 6 }
Range = {-3, 3, 1, 4}
In order to find the inverse relation the domain and range sets sre interchanged.
Thus, the inverse relation for the given relation can be written as,
{(-3, 1), (3, -2), (5, 1), (6, 4)} .
Hence, the inverse relation is given as {(-3, 1), (3, -2), (5, 1), (6, 4)}.

John is performing an experiment in which a solution alternates between a clear color and a bluish-purple color at a regular time interval. He observes that the time interval between color changes is 30 seconds (s). Sally replicates the experiment with the same solution, but at a temperature that is 10 degrees Celsius (°C) higher. What is the most likely time interval between color changes at this higher temperature?
Answer:
15 seconds
Step-by-step explanation:
The given parameters for the experiment are;
The time it takes the solution to change from a clear color to a bluish-purple color at a given temperature = 30 seconds
The temperature at which Sally replicates the experiment with the same solution = 10°C higher than the temperature the experiment was carried out by John
Given that the process involves a change in color, which is a characteristic of a chemical reaction, and that the rate of a chemical reaction increases as the temperature of the reacting system is increased, we have time it takes for the solution to change color at a temperature increased by 10°C, will be a time lesser than 30 seconds

5th box: 14
Step-by-step explanation: Plug in the formula y=3x+5. For example, you plug -1 as x, and you get y=(3)(-1)+5. 3 x -1 is -3, and then you add 5. The final answer is 2. Just do the same thing on the other boxes. Use the x values and plug it in into the formula shown.

unitary method examples.
Answer:
For example, if a car runs 44 km on 2 litres of petrol then we can use the unitary method to find out the kilometres it will cover on 1 litre of petrol. In other words, the method by which we find out the value of one unit and further use it to find the value of multiple units is known as the unitary method.

Fill in the blank to complete the equation below. 99 + 33 = 11(?+3)
Answer:
? = 9
Step-by-step explanation:
you know 99 + 33 = 132 so you can substitute that: 132 = 11 (? + 3). im going to change ? into x for now: 132 = 11 (x + 3). then distribute the 11 so 132 = 11x + 33. then subtract 33 from both sides (99 = 11x) and divide both side by 11 (x = 9) and you get 9!

Find one or more sequences of rigid motions and dilations that will map ABC to DEF Often, there is more than one sequence that will
nap a prelmage to a similar image. The table below provides spaces for two different sequences.
Begin by setting the scale factor of each dilation equal to the ratio you computed in question 1. Then find the rigid transformations needed to

Answer:
The y- intercept is 1
Step-by-step explanation:
Since the line crosses the y-axis at 1, the y-intercept is 1. Like the x-intercept. The line crosses the x-axis at um.. I would say about -1.5, so the x-intercept is -1.5.
