Answer:

x ≤ \frac{19}{4}

Step-by-step explanation:

Given

\frac{x-1}{3} - 2 ≤ \frac{5-2x}{6}

Multiply through by 6 to clear the fractions

2(x - 1) - 12 ≤ 5 - 2x ← distribute and simplify left side

2x - 2 - 12 ≤ 5 - 2x

2x - 14 ≤ 5 - 2x ( add 2x to both sides )

4x - 14 ≤ 5 ( add 14 to both sides )

4x ≤ 19 ( divide both sides by 4 )

x ≤ \frac{19}{4}

7-4i divided by <br> 2+i <br> how to solve it?
cupoosta [38]
\cfrac{7-4i}{2+i}\\\\ = \cfrac{(7-4i)(2-i)}{(2+i)(2-i)} \\\\ =\cfrac{14-7i-8i-4}{4+1} \\\\= \cfrac{10-15i}{5} \\\\= \cfrac{5(2-3i)}{5} \\\\=2-3i

A person owned 300 shares of MNO common stock, which cost $23,400. MNO then had a 3-for-1 stock split. After the split, the pers
lutik1710 [3]
A 3-for-1 stock split means that the number of shares is multiplied by 3, 
and becomes 900 shares. 
Cost of one share before split: \frac{23,400}{300}=\$78
Cost of one share after split: \frac{23,400}{900}=\$26
Cost of 100 shares before split:78\times100=7800
Cost of 100 shares after split:26\times100=2600
The above sale result in loss of: 7800-2600=\$5200

Solve for xx. Round to the nearest tenth of a degree, if necessary.
Tanya [424]

Answer:

56.6 °

Step-by-step explanation:

For a RIGHT triangle    cos (x ) = adjacent leg / hypotenuse

                                      cos (x) = 4.4 / 8

                                            arc  cos (4.4/8) = 56.63 °  = ~ 56.6°

Please help!!!

Answer:

c. 2a^3x^4-3a^3x^3+a^4x^2

d. 63x^5y^3-30x^2y^4-7x^3y^2

Step-by-step explanation:

For this exercise you need to remember the following:

 1. The multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-

2. The Product of powers property, which states that:

(a^m)(a^n)=a^{(m+n)}

3. The Distributive property:

a(b\±c)=ab\±ac

Knowing that, you can solve the multiplication of the polynomials:

c. (-2ax^2+3ax-a^2)(-a^2x^2)=\\\\=(-2ax^2)(-a^2x^2)+(3ax)(-a^2x^2)+(-a^2)(-a^2x^2)=2a^3x^4-3a^3x^3+a^4x^2

d. (6.3x^3y-3y^2-0.7x)(10x^2y^2)=\\\\=(6.3x^3y)(10x^2y^2)+(-3y^2)(10x^2y^2)+(-0.7x)(10x^2y^2)=63x^5y^3-30x^2y^4-7x^3y^2
