Answer:
D
Step-by-step explanation:
4.2 precent of 5000 is 210. You multiply that by the year (4) because he paid 4.2 of 5000 anually. If you multiply that the answer should be 840.
3.9 precent of 5000 is 195. If you multiply that again by 6 (the year) because he paid 3.9 of 5000 anually. If you multiply that your answer should be 1170.
Now after all that subtract. 1170-840= 330

Answer:
x = 28/97
y = 532/
Step-by-step explanation:
x + 5y = 20x + 3y
=> 5y - 3y = 20x - x
=> 2y = 19x
=> y = (19x)/2
x + 5y = 14
=> x + 5((19x)/2) = 14
=> x + (95x)/2 = 14
=> (2x + 95x)/2 = 14
=> 97x = 14(2)
=> 97x = 28
=> x = 28/97
=>y = (19x)/2 = (19(28))/(97(2)) = 532/194
Answer:
y = 17x
Step-by-step explanation:
By looking at the y-values of the table, we can see that they increase by 17 for every increase of 1 in the x-values.
This means are slope is 17.
We can prove this by plugging two points into the slope equation: (y₂ - y₁) / (x₂ - x₁)
(1, 17) & (3, 51)
(51 - 17) / (3 - 1)
Simplify the parentheses.
(34)/(2)
Divide.
17
Your slope is 17.
Plug this into your standard slope-intercept equation.
y = 17x + b
To find b, plug in a point to x and y. (1, 17)
17 = 17(1) + b
Multiply.
17 = 17 + b
Subtract.
b = 0
Your equation is: y = 17x + 0 or just y= 17x.
You can also tell by looking at the table. b is the y-intercept, or the value when x = 0. The table shows that when x = 0, y = 0. Therefore, b = 0.
Check your equation by plugging in the other point.
34 = 17(2)
34 = 34
Your equation is correct.

Answer:
5/6
Step-by-step explanation:
Suppose x = 0.83 (3 repeating).
Multiply both sides by 10:
10x = 8.3 (repeating 3)
Now, multiply both sides by 10 again:
100x = 83.3 (repeating 3)
So, we have:
100x = 83.3 (repeating 3)
10x = 8.3 (repeating 3)
We see that if we subtract these two equations, the repeating 3s cancel out, and we're left with:
100x - 10x = 83 - 8
90x = 75
x = 75/90 = 5/6
Thus, the answer is 5/6.
Hope this helps!
