Answer:

-4 < -13(a+6)-17

-4<-13a+(-78)-17

-4<-13a+(-95)

-4<-13a-95

91<-13a

-91>13a

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−4<−13(a+6)−17

−4<−13a−95

Step 2: Flip the equation.

−13a−95>−4

Step 3: Add 95 to both sides.

−13a−95+95>−4+95

−13a>91

Step 4: Divide both sides by -13.

-13a/-13 > 91/-31

ANSWER: a < -7

Explanation in words:

- The first step is to simplify both sides of the inequality and the answer will end up being as −4<−13a−95.

- The second step is to flip the equation and the answer will end up being as −13a−95>−4.

- The third step is to Add 95 to both sides of the equation and the answer will end up being as −13a>91.

- The last step is to Divide both sides by -13 and the answer will result as a < -7. So the answer is a < -7.

What's an equation that the passes through (-6,4) and is parallel to y=1/2x+8

deff fn [24]

By definition, if two lines share the same gradient, they are said to be parallel. So, we know for this equation, it must have a gradient of 1/2.

Now, since the point (-6, 4) passes through the line, we know it must satisfy the equation. Since we have a gradient/slope and a point, we can use the point-gradient form:

$y - y_1 = \frac{1}{2}(x - x_1)$ , where $(x_1, y_1)$ represents the points being passed through.

$y - 4 = \frac{1}{2}(x + 6)$
$2y - 8 = x + 6$
$2y = x + 14$
$y = \frac{1}{2}x + 7$
