Solve and write solution in interval notation 4(x+1)+3>x-5

soldi70 [24.7K]

Answer:

$\large\boxed{x\in\left(-\dfrac{13}{3},\ \infty\right)}$

Step-by-step explanation:

$4(x+1)+4>x-5\qquad\text{use the distributive property}\\\\4x+4+4>x-5\\\\4x+8>x-5\qquad\text{subtract 8 from both sides}\\\\4x>x-13\qquad\text{subtract}\ x\ \text{from both sides}\\\\3x>-13\qquad\text{divide both sides by 3}\\\\x>-\dfrac{13}{3}\to x\in\left(-\dfrac{13}{3},\ \infty\right)$

The estimated answer to a multiplication problem is 800,000. Which of the following expressions could result in this answer? Exp

EastWind [94]

Answer:

8,146 x 121

Step-by-step explanation:

This is a problem in which you need to measure your understading of "orders of magnitude."

If the estimated answer is $800000$ that means that we are looking at a multiplication in the "order of" $8*10^5$

You need to look at the "orders of magnitude" of the things you're multiplying. In the first case, we have $8146*12$ that would be "of the order of" $8*10^3$ times $10^1$ . So the whole multiplication would "of the order of" $8*10^4$ or near $80000$
