Tell whether the ordered pair is a solution to the equation.<br><br><br> (-2, 8); y = -2x - 1

slavikrds [6]

Answer:

No, the pair is not a solution to the equation.

Step-by-step explanation:

For the pair to be a solution to the equation, x = -2 must lead to y = 8, o =r vice versa. This leads to being able to solve it two ways either through x or through y.

I'll solve it through x:

y = -2x - 1

with x = -2

y = -2 * - 2 - 1

y = 4 - 1

y = 3

Since y = 3, when x = -2 the pair (-2,8) is not a pair to the solution of the equation.

PS: You can double check by solving through y and you'll find x = -4.5

irina1246 [14]

<h2>Answer:</h2>

<u>24.</u>

<h2>Step-by-step explanation:</h2>

<h3>1. Write the expression.</h3>

$(6x+3y)-\frac{z^{2}}{(2x)}$

<h3>2. Substitute the variables by the respective given value using <u>parenthesis</u>.</h3>

$(6(3)+3(4))-\frac{(6)^{2}}{(2(3))}$

<h3>3. Simplify the expression by applying the hierarchy or mathematical operations.</h3>

<em>a) Solve parenthesis.</em>

$(18+12)-\frac{(6)^{2}}{6}\\ \\30-\frac{(6)^{2}}{6}$

<em>b) Solve the exponent.</em>

$30-\frac{36}{6}$

<em>c) Divide.</em>

$30-6$

<em>d) Subtract.</em>

$24.$
