Slope-intercept form: y = mx + b

The equation in slope-intercept form is y = -3/4x + 0 or y = -3/4x

The slope intercept form:

y = mx + b

m - slope

b - y-intercept

We have: $m=-\dfrac{3}{4},\ b=0$

Therefore we have the equation:

$y=-\dfrac{3}{4}x+0\to\boxed{y=-\dfrac{3}{4}x}$

Solve x2 - 8x = 3 by completing the square. which is the solution set of the equation ?

Alisiya [41]

we know that

$(x-a)^{2}=x^{2}-2ax+a^{2}$

in this problem we have

$x^{2} - 8x = 3$

equate

$-8x=-2ax\\2a=8\\a=4$

substitute

$(x-4)^{2}=x^{2}-8x+16$

therefore

$x^{2} - 8x = 3$

$x^{2} - 8x+16 = 3+16$

$x^{2} - 8x+16 = 19$

rewrite as perfect square

$(x-4)^{2} = 19$

$(x-4) =(+/-)\sqrt{19}\\x=(+/-) \sqrt{19}+4$

therefore

the answer is

the solution set is

$x1= 4+\sqrt{19}\\x2=4- \sqrt{19}$

Which of these tables represents a function

kati45 [8]

Answer:

Step-by-step explanation:

A function must pass the Vertical Line Test. No 2 y-values can have the same x-values. Since the first 3 graphs fail to pass the vertical line test, our answer is Z.

Solve for x 1/4(4x-1)=-1/7-5/7

Ivanshal [37]

Answer:

$x=-\frac{17}{28}$

Step-by-step explanation:

$\frac{1}{4}(4x-1)=-\frac{1}{7}-\frac{5}{7}$

$x-\frac{1}{4}=-\frac{6}{7}$

$x = -\frac{6}{7} + \frac{1}{4}$

$x = -\frac{17}{28}$

plug $x$ in the equation to make sure of your answer:

$\frac{1}{4}(4x-1)=-\frac{1}{7}-\frac{5}{7}\\\frac{1}{4}(4(-\frac{17}{28}) -1)=-\frac{1}{7}-\frac{5}{7}\\-\frac{17}{28} -\frac{1}{4}=-\frac{6}{7}\\-\frac{6}{7}=-\frac{6}{7}$
