babunello [35]3 years ago
7 0

Answer:

x   ≥ -4

Step-by-step explanation:

-3x + 2 ≤ 14

Subtract 2 from each side

-3x+2-2  ≤ 14-2

-3x  ≤ 12

Divide each side by -3 .  Remember that dividing by a negative flips the inequality.

-3x/-3 ≥12/-3

x   ≥ -4

Can someone show me the answer and maybe the work
Tatiana [17]

Answer:

Solving the expression \frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3} we get \mathbf{\frac{1}{y^{\frac{5}{2} }x^3z^{\frac{5}{4} }}}

Step-by-step explanation:

We need to solve the expression:

\frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3}

We know the exponent rule: (a^n)^m = a^{nm}

\frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3}\\\\=\frac{y^2z^{\frac{1}{4}} }{z^{\frac{3}{2}}.x^3y^{\frac{9}{2} }}

Now, another exponent rule says that: \frac{a^m}{a^n}=a^{m-n}

=\frac{y^{2-\frac{9}{2}} z^{\frac{1}{4}-\frac{3}{2} } }{x^3}\\=\frac{y^{\frac{4-9}{2}} z^{\frac{1-3*2}{4} } }{x^3}\\=\frac{y^{\frac{-5}{2}}z^{\frac{-5}{4} } }{x^3}

We also know that: a^{-m}=\frac{1}{a^m}

=\frac{1}{y^{\frac{5}{2} }x^3z^{\frac{5}{4} }}

So, solving the expression \frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3} we get \mathbf{\frac{1}{y^{\frac{5}{2} }x^3z^{\frac{5}{4} }}}

If EG=19 and FG=12 then EF=?
Volgvan

Answer:

EF = 31

Step-by-step explanation:

Note that in both line segments (EG & FG), they both have point G in them. This means that point G is the shared point and the mid-point. Add the two line segments together to get the full segment.

EG + FG = EF

19 + 12 = 31

31 is your answer

Find the approximate side length of a square game board with an area of 179in ^2.
zysi [14]
<h3><u>Given</u><u>:</u><u>-</u></h3>

Area of a square game board = 179 inches ²

<h3><u>To</u><u> </u><u>be</u><u> </u><u>calculated</u><u>:</u><u>-</u></h3>

Calculate the side of given square game board.

<h3 /><h3><u>Formula</u><u> </u><u>applied</u><u>:</u><u>-</u></h3>

Area of square = ( Side )²

<h3><u>Solution</u><u>:</u><u>-</u></h3>

We know that,

Area of square = ( Side )²

★ Substituting the value in the above formula, we get :

=> 179 = ( Side )²

=> Side = √179

=> Side = 13.37 inches ( approx )

What is the first step in solving the equation 4.2y-5.2=18.5?
Sergeeva-Olga [200]
You would want to add 5.2 to both sides to get 4.2y by itself on one side. Then you would divide both sides by 4.2 to get y by itself. Whatever y equals is the answer. Hope this Helps!
