First rewrite the equation:8x + 4y = -56

Step 1: Add -4y to both sides.
<span><span><span>8x + </span>4y + <span>−4y </span></span>= −<span>56 + <span>−4y</span></span></span><span><span>8x = −<span>4y −</span></span>56</span>

Step 2: Divide both sides by 8.

<span><span><span><span><span>8x/8 </span></span></span>‌</span>= <span><span>‌<span><span><span>−<span>4y </span></span>−56</span>8</span></span>‌/8</span></span><span>

Tell whether x and y show direct variation. x + y = 6​
Over [174]
<h3>Answer: Not direct variation</h3>

The reason why is because it can't be written in the form y = kx

If we solved the given equation for y, we get y = -x+6. It has a y intercept of 6, but it should be zero if we wanted a direct variation equation.

Answer:

x ≤ - 27

Step-by-step explanation:

\frac{x}{-9}\ge \:3\\\\\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}\\\\\frac{x\left(-1\right)}{-9}\le \:3\left(-1\right)\\\\Simplify\\\\\frac{x}{9}\le \:-3\\\\\mathrm{Multiply\:both\:sides\:by\:}9\\\\\frac{9x}{9}\le \:9\left(-3\right)\\\\\mathrm{Simplify}\\\\x\le \:-27

Joaquin has a grade of 81 and 70 on her first two algebra test if she wants an average of 73 what possible score can she get on
Anvisha [2.4K]
81 + 70 + x = 3(73)
first multiply 3(73)

81 + 70 + x = 219
combine like terms

151 + x = 219
subtract 151 from both sides

x = 68

Joaquin needs to score a 68 on her next test to maintain an average of 73.
