Answer:

y = mx + b is the "slope-intercept" form of the equation of a line ;

We have y = -x + 6 ;

Then, m = - 1 ;

The "point-slope" form of the equation of a straight line is:

y - y1 = m(x - x1) ;

But, x1 = - 3 and y1 = 8 ;

We have y - 8 = (-1)( x + 3 );

Finally, y - 8 = -( x + 3 );

The right answer is the fourth choice;

________________________________________

y – 3 = (x – 1) ; the equation becames

y = x + 2 ;

The right answer is the third choice;

B) Explain how to compute 2 divide 1/4 with a common denominator.

Alex Ar [27]

Answer:

Step-by-step explanation:

2 divide 1/4 = $\frac{2}{1} : \frac{1}{4}$

What we have to do here is find a common denominator for both fractions, in this case 4, and change to equivalent fractions with a denominator of 4.

$\frac{8}{4} : \frac{1}{4}$

Then we divide across. The denominator of the answer will be 1 because the denominators are the same. Divide the numerators and get 8 ÷ 1, wich is just 8.

A system of equations is shown x-2y=-5 2x+4y=14

gladu [14]

Answer: here you go

Step-by-step explanation:

A) 2x + 4y = 14

B) 4x + y = 20

If you multiply equation A by -2, then when the equations are added, the x will be eliminated.

The solutions are:

X = 4.714285714285714

Y = 1.1428571428571428

Can someone please simplify the complex fraction?

dmitriy555 [2]

$\bf \cfrac{\qquad \frac{x+3}{4x^2-16}\qquad }{\frac{2x^2+10x+12}{2x-4}}\implies \cfrac{\frac{x+3}{4(x^2-4)}}{\frac{\underline{2}(x^2+5x+6)}{\underline{2}(x-2)}}\implies \cfrac{\frac{x+3}{4(x^2-2^2)}}{\frac{x^2+5x+6}{x-2}}\implies \cfrac{\frac{x+3}{4(x-2)(x+2)}}{\frac{(x+3)(x+2)}{x-2}}$

$\bf \cfrac{\underline{x+3}}{4\underline{(x-2)}(x+2)}\cdot \cfrac{\underline{x-2}}{\underline{(x+3)}(x+2)}\implies \cfrac{1}{4(x+2)}\cdot \cfrac{1}{x+2}
\\\\\\
\cfrac{1}{4(x+2)(x+2)}\implies \cfrac{1}{4(x^2+4x+4)}\implies \cfrac{1}{4x^2+16x+16}$
