121-12 is 109. That converted to celcius i believe is 42.8. Rounded its 43 degrees
Hope it helps!!!
Answer:
(-5, 18)
Step-by-step explanation:
7x + 2(3 − 3x) = 1 simplifies to
7x + 6 - 6x = 1, which, in turn, simplifies to:
x = -5
Using y = 3 - 3x (see Step 1), we find that y = 3 - 3(-5) = 3 + 15 = 18.
Thus, the solution is (-5, 18).
Answer: Luis’s first step was incorrect, because he flipped the inequality sign when he subtracted
Step-by-step explanation:
Given: Amelia, Luis, Shauna, and Clarence used different approaches to solve the inequality
7.2b + 6.5 > 4.8b – 8.1.
If Luis started by subtracting 4.8b from both sides ,then he would get
7.2b + 6.5 - 4.8b> 4.8b – 8.1- 4.8b
⇒2.4b + 6.5 > – 8.1. But he wrote 2.4b + 6.5 < – 8.1 by flipping the inequality sign which was not correct .
The sign of inequality get flipped if we multiply or divide a negative numbers to the both sides .
Therefore, Luis’s first step was incorrect, because he flipped the inequality sign when he subtracted.
The value of logarithm expression 2log₅(5x³) + (1/3)log₅(x² + 6) is simplified as log₅[{25x⁶}{∛(x² + 6)}].
<h3>What is a logarithm?</h3>
Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.
The logarithmic expression is given as

We know that formulas

Then we have
![\rightarrow \log _5(5x^3)^2 + \log _5(x^2 +6)^{1/3}\\\\\rightarrow \log _525x^6 + \log _5\sqrt[3]{(x^2 +6)}\\\\\rightarrow \log _5 25x^6 (\sqrt[3]{(x^2 +6)})](https://tex.z-dn.net/?f=%5Crightarrow%20%5Clog%20_5%285x%5E3%29%5E2%20%2B%20%20%5Clog%20_5%28x%5E2%20%2B6%29%5E%7B1%2F3%7D%5C%5C%5C%5C%5Crightarrow%20%5Clog%20_525x%5E6%20%2B%20%20%5Clog%20_5%5Csqrt%5B3%5D%7B%28x%5E2%20%2B6%29%7D%5C%5C%5C%5C%5Crightarrow%20%5Clog%20_5%2025x%5E6%20%28%5Csqrt%5B3%5D%7B%28x%5E2%20%2B6%29%7D%29)

A and B will use the formulas: 4/3 * pi * r^3
A = 8.181 in^3
B = 9.471 in^3
C write an inequality
8.181 < x < 9.471 in^3
