Determine whether the statement is sometimes, always, or never true. If ax+b-4=b and doesn’t equal 0 then x=4/a?

attashe74 [19]

Start with expression $ax+b-4=b.$

1. Separate terms - with x leave in left side, without x write in right side:

$ax=b-b+4,\\ \\ax=4.$

2. Divide the last expression by a ( $a\neq 0$ ):

$x=\dfrac{4}{a}.$

Answer: this statement is true when $a\neq 0$ .

Solve each equation. Identify the solutions as rational or irrational numbers.

Fiesta28 [93]

$\textbf{a)}\\\\~~~~~~~x(3x-4)=5\\\\\implies 3x^2 -4x = 5\\\\\implies 3x^2 -4x=5\\\\\implies x^2 - \dfrac 43 x = \dfrac 53\\ \\\implies x^2 - 2\cdot \dfrac 23 \cdot x + \left( \dfrac 23 \right)^2 - \left( \dfrac 23 \right)^2 = \dfrac 53\\\\\implies \left(x-\dfrac 23 \right)^2 = \dfrac 53 + \dfrac 49\\\\\implies \left(x-\dfrac 23 \right)^2= \dfrac{19}{9}\\\\\implies x- \dfrac 23 = \pm\dfrac{\sqrt{19}}3\\\\\implies x=\dfrac 23 \pm\dfrac{\sqrt{19}}3\\\\$

$\text{The solutions are irrational.}\\\\\\\textbf{b)}\\\\~~~~~~~(3x-2)^2 = \dfrac 14\\\\\implies 3x -2 = \pm \dfrac 12\\\\\implies 3x = 2\pm \dfrac 12\\\\\implies x = \dfrac 23 \pm \dfrac 16\\\\ \implies x = \dfrac 56 ,~~ x =\dfrac 12 \\ \\\text{The solutions are rational .}$

A pet store employee measures the lengths of two pet snakes, Noodles and Squiggles. Noodles measures 30 inches long, and Squiggl

deff fn [24]

Answer:

Squiggles

Step-by-step explanation:

steps

convert the length of squiggles from feet to inches
find the difference

1 feet = 12 inches

2 feet = 2 x 12 = 24 inches

length of squiggles = 24 + 10 = 34 inches

squiggles is longer because 34 is greater than 30

difference = 34 - 30 = 4
