Answer:

x ∈ IR / x\geq -2 or you can also write

x ∈ IR / x ∈ [-2 , + ∞)

Step-by-step explanation:

We have the following inequality :

2(3x-1)\geq 4x-6

To find the solution set of the inequality we need to find the values of x that satisfy the inequality.

Working with the inequality :

2(3x-1)\geq 4x-6

6x-2\geq 4x-6

2x\geq -4

x\geq \frac{-4}{2}

x\geq -2

The solutions of the inequality are all real numbers greater or equal to -2

We can write this as

x ∈ IR / x\geq -2

Or either using and interval as

x ∈ IR / x ∈ [-2 , + ∞)

Answer:

35 and 55

Step-by-step explanation:

x+(2×-15)=90

PLEASE HELP!!! WILL REWARD BRAINLIEST!!!

Answer:

The approximate monthly rate of growth is 1.24%

Step-by-step explanation:

we have the future value formula

F=P(1+r)^t

we have

r=16\%=16/100=0.16 ----> annual interest rate

so

F=P(1+0.16)^t

F=P(1.16)^t

Find the approximate monthly rate of growth

Remember that

1\ year=12\ months

so

Divide the number of periods t by 12

F=P(1.16)^{\frac{t}{12}}

Applying power rules property

F=P(1.16^\frac{1}{12})^t

F=P(1.0124)^t}

1.0124-1=0.0124

Convert to percentage

0.0124*100=1.24\%

therefore

The approximate monthly rate of growth is 1.24%

horsena [70]
We have that

<span>y=2sinx-cosx
y=cosx
</span>over the interval 0≤x≤pi/2-------> 0≤x≤1.57

using a graph tool
see the attached figure

the solution in the given interval is the point (pi/4, 0.707)
the y-value of the point of intersection is 0.707 -----> √2/2

the answer is the option 
<span>b. (square root of 2)/2</span>
