What is the value a and b in<br> The equation<br><br> a(3x -8)=b-18x

Misha Larkins [42]

Answer:

$a=\frac{b-18x}{3x-8}\\b=3ax-8a+18x$

Step-by-step explanation:

<u>Solving for A:</u>

$a(3x-8)=b-18x$ - Given

$\frac{a(3x-8)}{(3x-8)}=\frac{b-18x}{(3x-8)}$ - Divide both sides by 3x-8 to isolate a

$a = \frac{b-18x}{3x-8}$ - Simplify

<u>Solving for B:</u>

<u /> $a(3x-8)=b-18x$ - Given

$3ax-8a=b-18x$ - Distribute the parenthesis (distributive property)

$3ax-8a+18x=b$ - Add 18x to both sides to isolate b

Which number line represents the solution set for the inequality –(1/2)x ≥ 4?

sergejj [24]

When the sign is ≤ or ≥ (less/greater than or equal to), the dot is filled in.

When the sign is < or >, the dot is not filled in and looks like this o

To find out which number line represents the solution set, simplify the inequality and isolate x

$-\frac{1}{2}x\geq4$ Multiply -2 on both sides to get rid of -1/2

$(-2)(-\frac{1}{2}x)\geq4(-2)$

x ≤ -8 (The sign flips when you multiply/divide a negative number on both sides of the inequality)

so you get x is greater than or equal to -8, so you have a filled in circle on -8, and the arrow should be going to the right since x is greater than -8
