If ba-cd =b which expression represents "a"?A. b-cd/bB. b+cd/bC. b/b-cdD. b/b+cd

navik [9.2K]

Isolating the variable 'a' in the expression, we have:

$\begin{gathered} ba-cd=b \\ ba=b+cd \\ a=\frac{b+cd}{b} \end{gathered}$

So the correct option is B.

[No links please and explain it out.♡︎]

Sholpan [36]

Answer:

y = mx+b

m represents the slope and b represents the y-intercept

since you have the slope and a point you can find here the line crosses the y-axis

y = -1/2x + b

the point (-14, 6) can be substituted into the eq for x and y

(6) = -1/2(-14)+b

6 = 7 +b (subtract 7 from both sides)

-1 = b

The line crosses the y-axis at -1

Hey can you please help me posted picture of question

larisa [96]

$(5x - 2)^2 = 15$

Square root both sides:
$5x - 2 = \pm\sqrt{15}$

Add 2 to both sides:
$5x = pm\sqrt{15} + 2$

Divide both sides by 5:
$x = \dfrac{ \pm\sqrt{15} + 2}{5}$

Answers:
$x = \dfrac{ \sqrt{15} + 2}{5} \ or \ \dfrac{ - \sqrt{15} + 2}{5}$

Answer: (B) and (E)
