There are different kinds of expression. The expressions that is equivalent to 4r + 3s - 2r is 2r +3s.
How do you solve from Expression to equivalent?Equivalent expressions are known to be any kind of expressions that does the same thing even if they may have different looks.
Note that two algebraic expressions are said to be equivalent, when the two expressions do have the same value in terms of value(s) and variable(s).
Thus in 4r + 3s - 2r, we collect like terms:
4r -2r -3s
=2r-3s
Therefore, the answer is 2r-3s

How do you solve this without using a calculator
Answer:
A
Explanation:
You must know the basics of Trigonometry to solve this.
First, you must know that
[tex] \frac{3\pi}{4} [/tex]
lies in the second quadrant, so sin is negative.
Next, since
pi/4, is the reference angle of 3 pi/4, this means that we can set up a right triangle with pi/4 as an angle, we get
[tex] \cos( \frac{3\pi}{4} ) = \frac{ \sqrt{2} }{2} [/tex]
[tex] \sin( \frac{\pi}{4} ) = - \frac{ \sqrt{2} }{2} [/tex]
So the answer is A

Put the following equation of a line into slope-intercept form, simplifying all fractions.
3x + 15y= −60
Answer:
y = -1/5x - 4
Explanation:
Slope-intercept form: y = mx + c
m = gradient
y = y-intercept
3x + 15y = -60
1. Take away 3x from both sides.
15y = -3x - 60
2. Divide by 15 from both sides.
y = -3/15x - 60/15
3. Simplify.
y = -1/5x - 4

A survey showed that 34 % of human resource professionals are at companies that rejected job candidates because of information found on their social media. If 27 human resource professionals are randomly selected, would 16 be a significantly high number to be at companies that rejected job candidates because of information found on their social media? Why or why not?
Using the binomial distribution, it is found that since 16 is more than 2.5 standard deviations above the mean, it is a unusually high number.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
A measure is considered to be unusually high if it is more than 2.5 standard deviations above the mean.
In this problem, we hav ehtat:
34% of companies reject candidates because of information found on their social media, hence p = 0.34.27 human resource professionals are randomly selected, hence n = 27.Then, we find the threshold for unusually high values as follows:
E(X) = np = 27 x 0.34 = 9.18
[tex]\sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{27(0.34)(0.66)} = 2.46[/tex]
T = 9.18 + 2 x 2.46 = 14.1.
Since 16 is more than 2.5 standard deviations above the mean, it is a unusually high number.
