Answer:
1) 199
2) 899
Step-by-step explanation:
1)
The 2-digit number is the number formed from unit-digit and ten-digit
∵ The greatest digit is 9
→ To form the greatest 2-digit number use 9 as ten-digit and unit-digit
∴ The greatest 2-digit number is 99
The 3-digit number is the number formed from unit-digit, ten-digit, and hundred-digit
∵ The smallest digit is 0
→ To form the smallest 3-digit number use 0 as ten-digit and unit-digit,
we can not use 0 for the hundred-digit so use 1 as hundred-digit
∴ The smallest 3-digit number is 100
∵ The sum of them = 99 + 100
∴ Their sum is 199
2)
→ To form the greatest 3-digit number use 9 as hundred-digit, ten-digit,
and unit-digit
∴ The greatest 3-digit number is 999
∵ The smallest 3-digit number is 100
∵ The difference between them = 999 - 100
∴ The difference between them = 899
Answer: The answer to this question is 8a^2-368a+ab-46
Step-by-step explanation: In this problem we have to multiply the two brackets in order to get the product.
a×a=a^2
a×b=ab
Answer:
1 on a question: The sum of two angles is 90°. The difference of twice the larger angle and the smaller angle is 105º. The system of linear x+y=90 equations represents this 2x - y = 105 situation where x is the larger angle and y is the smaller angle. Find the measures of the two angles.
Step-by-step explanation:
Answer:
The answer is<u><em> B) g(x) is shift 5 units to the right and 2 units up from f(x).</em></u>
Step-by-step explanation:
The equation that is given in this item can be written for clarity as follows:
g(x) = 1/(x - 5) + 2
It can be seen that the x-component is subtracted with 5 and the g(x) which would lie in the y-axis is added with two. This suggests that the graph of this equation is shifted to the right by 5 units and upwards by 2 units compared to the graph of the parent function.
