Solve: 7 x + 2 y = 16; -21 x-6 y = 24 Solve : 7 x + 2 y = 16 ; -21 x - 6 y = 24​
Marat540 [252]

Answer:

No solution

Step-by-step explanation:

<h3>Solving system of linear equations:</h3>

 7x + 2y = 16 ----------------(I)

-21x - 6y = 24 -----------------(II)

\sf \dfrac{a_1}{a_2}=\dfrac{7}{-21}=\dfrac{-1}{3}\\

\sf \dfrac{b_1}{b_2}=\dfrac{2}{-6}=\dfrac{-1}{3}

\sf \dfrac{c_1}{c_2} =\dfrac{16}{24}=\dfrac{2}{3}\\\\ \dfrac{a_1}{a_2}=\dfrac{b_1}{b_2} \neq  \dfrac{c_1}{c_2}

So, the lines are parallel and has no solution

Write a sequence with exactly 5 terms and follow the pattern rule:
Aloiza [94]

Answer:

The pattern. 1, 4, 9, 16, … has no common difference. An explicit pattern rule is a pattern rule that tells you how to get any term in the pattern without listing all the terms before it. For example, an explicit pattern rule for 5, 8, 11, 14, … uses the first term (5) and the common difference (3).

Evaluate (625/16)^1/4.Please answer correctly as soon as possible​
podryga [215]

Answer:

=  \frac{5}{2}  = 2 \frac{1}{2}

Step-by-step explanation:

( \frac{625}{16}  {)}^{ \frac{1}{4} }  \\  \sqrt[4]{ \frac{625}{16} }  =  \frac{ \sqrt[4]{625} }{ \sqrt[4]{16} }   \\  \frac{ \sqrt[4]{ {5}^{4} } }{ \sqrt[4]{16} }  =  \frac{ \sqrt[4]{ {5}^{4} } }{ \sqrt[4]{ {2}^{4} } }  =  \frac{5}{2}

\boxed{\green{=  \frac{5}{2}  = 2 \frac{1}{2}}}
