Solve the inequality 5y+4 ≤ 22-y and graph the solution set on a number line. Please explain how to do it!
gtnhenbr [62]

Answer:

y≤3

Step-by-step explanation:

5y+4≤22−y

<em>Step 1: Simplify both sides of the inequality.</em>

5y+4≤−y+22

<em>Step 2: Add y to both sides.</em>

5y+4+y≤−y+22+y

6y+4≤22

<em>Step 3: Subtract 4 from both sides.</em>

6y+4−4≤22−4

6y≤18

<em>Step 4: Divide both sides by 6.</em>

6y/6≤18/6

y≤3

In 2013 number of students in a small school is 284.it is estimated that student population will increase by 4 percent
BaLLatris [955]

The situation can be modeled by a geometric sequence with an initial term of 284. The student population will be 104% of the prior year, so the common ratio is 1.04.

Let \displaystyle PP be the student population and \displaystyle nn be the number of years after 2013. Using the explicit formula for a geometric sequence we get

{P}_{n} =284\cdot {1.04}^{n}P

n

=284⋅1.04

n

We can find the number of years since 2013 by subtracting.

\displaystyle 2020 - 2013=72020−2013=7

We are looking for the population after 7 years. We can substitute 7 for \displaystyle nn to estimate the population in 2020.

\displaystyle {P}_{7}=284\cdot {1.04}^{7}\approx 374P

7

=284⋅1.04

7

≈374

The student population will be about 374 in 2020.

What is the x-intercept of the graph of y =x2-4x+4
oksano4ka [1.4K]
      y = x² - 4x + 4
      0 = x² - 4x + 4
      0 = x² - 2x - 2x + 4
      0 = x(x) - x(2) - 2(x) - 2(-2)
      0 = x(x - 2) - 2(x - 2)
      0 = (x - 2)(x - 2)
      0 = (x - 2)²
      0 = x - 2
   + 2      + 2
      2 = x
(x, y) = (2, 0)

6^3+5(8+0.2)= can someone tell me the steps i know its 257 i need the steps
Sav [38]

Step 1 distribute the 5 across (8+0.2)

6^3+5(8+0.2)

6^3+40+1

6^3+41 (<em>I simplified the +40 and the +1</em>)

Step 2 take 6 to the power of 3

6^3+41

6x6x6     6x6=36     36x6=216

216+41 (<em>Simplify!</em>)

257


I hope this helped!
