Alex_Xolod [135]

Answer:

-14 > -16

Step-by-step explanation:

> = greater than

< = less than

To help you know which is less than what in negative numbers use a number line.

In negative numbers what would usually be bigger than the other number is smaller in negatives. like 69 is bigger than 34 but im negatives -69 would be smaller than -34.

There are 267 students and 21 adults going on a field trip an equal number of people will ride on each bus there are 9 buses how

DiKsa [7]

Answer:

The number of people on each bus is 32

Step-by-step explanation:

We are given

Total number of students =267

Total number of adults =21

So,

Total number of passengers = ( Total number of students)+(Total number of adults)

now, we can plug values

Total number of passengers =267+21

Total number of passengers =288

We are given

Number of buses=9

so,

Number of passengers on each bus = (total number of passengers)/( Number of buses)

now, we can plug values

Number of passengers on each bus is

$=\frac{288}{9}$

$=32$

So,

The number of people on each bus is 32

Exponential Equation WITHOUT CALCULATOR

Alborosie

Multiply both sides of the first equation by $2^x$ :

$2^x-2^{-x}=4\implies 2^{2x}-1=4\cdot2^x\implies 2^{2x}-4\cdot2^x-1=0$

This is quadratic in $2^x$ ; to make this clear, substitute $y=2^x$ . Then

$y^2-4y-1=0\implies y=2\pm\sqrt5$

One of these solutions for $y$ is negative. But, if $x$ is real, then $y=2^x$ is always supposed to be positive, so we can throw out the negative root, leaving $y=2+\sqrt5$ .

We actually don't have to solve for $x$ exactly. We can just rewrite the next two equations in terms of $y$ .

$2^{2x}+2^{-2x}=(2^x)^2+(2^{-x})^2=y^2+\dfrac1{y^2}$

$2^{3x}-2^{-3x}=y^3-\dfrac1{y^3}$

Since $y=2+\sqrt5$ , we get

$(2+\sqrt5)^2+\dfrac1{(2+\sqrt5)^2}=18$

$(2+\sqrt5)^3-\dfrac1{(2+\sqrt5)^3}=76$

Two step inequalities intergers

wlad13 [49]

.Two-step inequalities are very easy to solve and the rules you have to adhere to are the same as for the one-step inequalities – remember that you need to change the sign of inequality when multiplying or dividing the whole inequality with a negative number. The order of operations will not come into play often since there are not many operations to perform here.

Hope this helps:)
