Answer: Choice A
Jackson likes earning rewards on his purchases.
=========================================================
Explanation:
Debit cards do not give out reward points for using them. Credit cards on the other hand do offer such a feature. So if Jackson wants reward points, he'll need to use a credit card. This is why choice A is the answer.
Choice B is ruled out because shopping locally could involve either type of card, or simply cash, depending the merchant's payment preferences. There's no incentive to use a credit card here.
Choice C is ruled out because a debit card is tied to a checking account. Blake making weekly transfers to this account seems to heavily imply he uses it a lot; therefore, he's likely using a debit card here.
Choice D is ruled out because Jena being careful with money would likely use a debit card. With debit cards, you use only the money in the checking account. No money is borrowed like with a credit card. This means there's no worry about going into debt when using a debit card.
Evaluate the expression: 4x - 2y if x is 7 and y is -3
Plug in the values of the variables:-
[tex]\sf{4x-2y}[/tex]
[tex]\sf{4(7)-2(-3)}[/tex]
[tex]\sf{28+6}[/tex]
[tex]\sf{34}[/tex]
note:-Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I'll comment and/or edit my answer :)
Answer:
34
Step-by-step explanation:
We have to find the value of the expression ( 4x - 2y ).
Also, given that,
x = 7
y = -3
So, to find the value of the given expression, you have to replace x and y with 7 & -3 respectively.
Let us solve it now.
4x - 2y
4 × 7 - 2 × -3
28 + 6

You have 8,640 grams of a radioactive kind of cesium. If its half-life is 30 years, how much
will be left after 120 years?
grams
The mass of cesium left afer 120 years if the original mass of cesium is 8640 with an half-life of 30 years, is 540 grams.
What is half-life?This can be defined as the time taken for half the amount of a radioactive substance to decay.
To calculate the amount of cesium left after 120 years, we use the formua below.
Formula:
R' = R/([tex]2^{T/t}[/tex])............. Equation 1Where:
R = Original amount of CesiumR' = New amount of cesiumT = Total timet = Half-lifeFrom the question,
Given:
R = 8640T = 120 yearst = 30 yearsSubstitute these values into equation 1
R' = 8640/([tex]2^{120/30}[/tex])R' = 8640/[tex]2^{4}[/tex]R' = 8640/16R' = 540 grams.Hence, The mass of cesium left afer 120 years is 540 grams.

solve this system of equations 2x+4y=-48
Answer:
x=-24-2y
y=-12-x/2
Step-by-step explanation:
To solve for x move everything to one side, 2x=-48-4y, then you can divide by 2 to just get x, x=-24-2y.
To solve for y move everything to one side, 4y=-48-2x, then you can divide by 4 to just get y, y=-12-x/2.

a ball is thrown vertically upward from the ground. it's distance in feet from the ground in t seconds is s=-16t+224t. after how many seconds will the ball be 768 feet from the ground? pls help!!!
Answer:
3.692seconds
Step-by-step explanation:
distance s is represented by the following equation s=-16t+224t
given the distance=768ft
replace s by 768 in the equation to find t (time):
768=-16t+224t
768=208t
t=768/208 =48/13 =3.692seconds

so that gives us the point (0 , 27) on the imaginary plane, and we also know the line goes through the origin, since it'd be a line in component form, and to get the equation of a line we only need two points off of it, let's use those two.
[tex]\stackrel{origin}{(\stackrel{x_1}{0}~,~\stackrel{y_1}{0})}\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{27}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{27}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{0}-\underset{x_1}{0}}}\implies \cfrac{27}{0}\implies und efined[/tex]
a line with an undefined slope is a vertical line, namely in this case x = 27.

x=0
Step-by-step explanation:
add 3 to both sides
subtract 4 from both sides
[tex]\sqrt{x} +4-3=1\\\sqrt{x} +4=4\\\sqrt{x} =0[/tex]
Answer: x=12
√x+4 - 3 = 1
(√x+4 - 3) + 3 = 1 + 3
√x + 4 = 4
(√x+4)^2 = 4^2
√(x+4)^2 = 16
x+ 4 = 16 (cancels out the square root)
(x + 4) + (-4) = 16 + (-4)
x + 4 - 4 = 16 - 4
And then just solve it out
x = 12

Select from the drop-down menu to correctly complete the sentence.
The spinner is expected to have to spin approximately
times for a multiple of 5 has been spun 8 times.
Answer: The awnser is 48
Step-by-step explanation: I took the quiz
6.03 Quiz: Use Theoretical Probability to Predict
It is expected to take 48 spins for a multiple of 5 to be spun 8 times.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Since there are 12 sectors, the probability of landing on a multiple of 5 is 2/12 or 1/6.
The probability of not landing on a multiple of 5 is 5/6.
We can use the geometric distribution formula to find the expected number of spins:
E(X) = 1/p, where p is the probability of success.
As per the question, the probability of success is 1/6.
Therefore, E(X) = 1/(1/6) = 6.
We need to spin a multiple of 5 8 times, so we multiply the expected number of spins by 8:
6 x 8 = 48.
Therefore, we can expect to spin a multiple of 5-8 times after 48 spins.

The graph below represents an employee's earnings based on units sold. What can be interpreted from the slope of this graph?
A.
The employee earns an additional $100 for every one unit sold.
B.
The employee earns an additional $100 for every ten units sold.
C.
The employee earns an additional $1,000 for every one unit sold.
D.
The employee earns an additional $31,000 for every ten units sold.
Answer:
A
Step-by-step explanation:
From inspection of the graph, we can see that every time the x-value increases by 10, the y-value increases by 1000.
So, the employee earns an additional $1000 for every 10 units sold.
To calculate how much the employee earns for every 1 unit sold, divide $1000 by 10:
1000 ÷ 10 = 100
Therefore, the employee earns an additional $100 for every one unit sold.
Proof
This can be proved by calculating the slope (gradient) of the graph:
[tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
where [tex]\sf (x_1,y_1)[/tex] and [tex]\sf (x_2,y_2)[/tex] are two points on the line
When picking the two points, remember that the y-values are in thousands of dollars.
Two points on the line:
(0, 30000) and (20, 32000)
Substituting these into the formula:
[tex]\sf \implies slope=\dfrac{32000-30000}{20-0}=\dfrac{2000}{20}=100[/tex]
Therefore, the employee earns an additional $100 for every one unit sold.
