Answer:
4 = 16,000
8 = 32,000
10 = 40,000
Step-by-step explanation:
4 x 4 = 16 then add the zeros and then you have 16,000. Same thing with 8. 4 x 8 = 32 then add the zeros. Also goes for 10. 4 x 10 = 40 then add the zeros.
Answer:
Domain: (-∞, ∞)
Range: (0,∞)
Step-by-step explanation:
<em>Exponential functions are curves which approach a horizontal asymptote usually at y=0 or the x-axis unless a value has been added to it. If it has, the curve shifts. This function has addition on the exponent but not to the whole function so it does not change the asymptote. Its y - values remain between 0 and ∞. This is the range, the set of y values.
</em>
<em>
</em>
<em>However, the range of exponentials can change based on the leading coefficient. If it is negative the graph flips upside down and its range goes to -∞. This doesn't have it either.
</em>
<em>
</em>
<em>The addition to 1 on the exponent shifts the function to the left but doesn't change the range.
</em>
<em>
</em>
<em>In exponential functions, the x values are usually not affected and all are included in the function. Even though it shifts, the domain doesn't change either. Its domain is (-∞, ∞).

Answer: 3(2)^2 + 4(3)^2
Step-by-step explanation:
First do what is replacing the variables by changing X to 2 and Y to -3
3(2)^2 + 4(-3)^2 = 3(4) + 4(9) = 12 + 36 = 48
Answer:
9x-7y
Step-by-step explanation:
Answer: x = 7, y = -3
<u>Step-by-step explanation:</u>
3y = 26 - 5x --> added 5x to both sides to get: 5x + 3y = 26
Elimination method (I am going to eliminate "x":
5x + 3y = 26 → 6(5x + 3y = 26) → 30x + 18y = 156
6x + 7y = 21 → -5(6x + 7y = 21) → <u> -30x - 35y</u> =<u> -105</u>
-17y = 51
<u> ÷-17 </u> <u>÷-17</u>
y = -3
Now, input y = -3 into one of the original equations to solve for "x":
3y = 26 - 5x
3(-3) = 26 - 5x
-9 = 26 - 5x
-9 -26 = -5x
-35 = -5x
7 = x
