Answer:
- Step 1, all the exponents are increased by 4
Step-by-step explanation:
<u>The three steps are</u>
- (x⁻² × y⁴ /y × x⁴ × x⁴ × y⁻²)⁴ =
- x²×y⁸/y⁴×x⁸×x⁸×y² =
- x²×y⁸/y⁶×x¹⁶
<u>Correct solution should be:</u>
- (x⁻² × y⁴ /y × x⁴ × x⁴ × y⁻²)⁴ = all powers inside the parenthesis should be multiplied by 4 as per power of the power (xᵃ)ᵇ = xᵃᵇ
<u>This would give next steps:</u>
- x⁻⁸×y¹⁶/y⁴×x⁸×x⁸×y⁻⁸ =
- x⁻⁸×y¹⁶/x¹⁶×y⁻⁴ =
- y²⁰/x²⁴
<u>Answer options:</u>
Step 1, all the exponents are increased by 4
- There should be multiplication of powers. (It is close option but is not fully correct as not all the exponents increased by 4, for example y became y⁴)
Step 2, the exponents of the same base are added during multiplication
Step 3 wasn't performed yet, there was step 1 and 2.
- So answers about step 3 are irrelevant
Answer:
3a) y = -0.1x +26000
3b) $16500
4a) y = 8.2x - 16451.27
4b) 79.93
Step-by-step explanation:
3a) y = -0.1x +26000
3b) If the odometer reads 95000 we need to plug in that value for x: y = -0.1(95000) + 26000 = $16500
4a) y = 8.2x - 16451.27
4b) To estimate the number the rabbits in the year 2016, we need to plug in that value for x: y = 8.2(2016) - 16451.27 = 79.93 = 80 rabbits
Answer: 15
Step-by-step explanation:
Let x = the number of players the team can bring to the tournament.
Given: Soccer team raised $2158 for tournament.
Bus rent = $1130.50 and budget per player for meals = $68.50
Total cost of tournament = Bus rent + (budget per player for meals) ( number of players the team)
Hence, the number of players the team can bring to the tournament = 15
Domain is all real numbers.
Range is f(x) <= 5
The answer is a. to be a function there can’t be an x value that is the same to a different y value. so as an example (6,7) (3,2) (5,6) (6,3) is not a function because 6 appears 2 times as an x value but with different y values. but you can have the same y value.
