The graph of a line has a slope of -3 and passes through the point (-6,-4).

prohojiy [21]

Answer:

(A) y+4=-3(x+6)

Step-by-step explanation:

The point-slope form of the equation of a line whose slope is m and passes through the point $(x_1, y_1)$ is: $y-y_1=m(x-x_1)$

Given the point: $(x_1, y_1)=(-6,-4)$

Slope, m=-3

$x_1=-6\\y_1=-4$

Substituting these values into: $y-y_1=m(x-x_1)$ , we obtain the point slope form of the equation:

$y-(-4)=-3(x-(-6))\\\\y+4=-3(x+6)$

The correct option is A.

Please help me with number six

Tpy6a [65]

$w = 2x = 2( \frac{y}{3}) \\ v = 2w = 2 \times 2( \frac{y}{3} ) \\ v + w + x + y = 180 \\ \frac{4}{3} y + \frac{2}{3} y + \frac{y}{3} + y = 180 \\ y( \frac{4}{3} + \frac{2}{3} + \frac{1}{3} + 1) = 180 \\ y = \frac{180}{()}$

Find the diameter of a circle with an area of<br>95.03 square feet.<br>

ra1l [238]

For this case we have that the area of a circle is given by:

$A = \pi * r ^ 2$

Where:

r: It is the radius of the circle

By clearing the radio we have:

$r = \pm \sqrt {\frac {A} {\pi}}$

We take the positive value:

$r = \sqrt {\frac {A} {\pi}}\\r = \sqrt {\frac {95.03} {\pi}}\\r = 5.50 \ ft$

The diameter is twice the radius:

$d = 11$

Answer:

$11 \ ft$
