3/4 = 6/8 and 3/8 is half of 6/8. If she wanted to give each friend 3/8 of the bag, she could give a portion to only 2 friends.

A line passes through (3, -2) and (6, 2). a. Write an equation for the line in point-slope form. b. Rewrite the equation in stan

koban [17]

Answer:

(a)

Given: A line passes through the points (3, -2) and (6, 2)

Point slope form: An equation of line passing through two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by:

$y -y_1=m(x-x_1`)$ .....[1] where m is the slope of the line.

Calculate first the slope of the line:

Slope(m) = $\frac{y_2-y_1}{x_2-x_1}$

Substitute the given points;

$m = \frac{2-(-2)}{6-3}=\frac{2+2}{3} =\frac{4}{3}$

Substitute the value of m in [1] ;

$y - (-2) = \frac{4}{3}(x-3)$

$y+2=\frac{4}{3}(x-3)$ ......[1]

therefore, the equation of line in point slope form is, $y+2=\frac{4}{3}(x-3)$

(b)

to find the standard form of the equation [1]

Multiply both sides by 3 in [1] we get;

$3(y+2) = 4(x-3)$

using distributive property; $a\cdot (b+c) = a\cdot b + a\cdot c$

3y + 6 = 4x -12

Subtract 3y to both sides we get;

3y + 6 -3y = 4x - 12 - 3y

Simplify:

6 = 4x - 3y -12

Subtract 6 from both sides we get;

0 = 4x - 3y -12-6

Simplify:

4x - 3y - 18 =0

Therefore, the standard form of the equation is; 4x - 3y - 18 =0

A roof has the shape of an isosceles triangle with equal sides 8 cm long and base 12 m long. What is the measure of the angle of

victus00 [196]

Answer:

41 degrees to the nearest degree.

Step-by-step explanation:

A line drawn from the vertex and bisecting the base forms 2 right triangles.

The base of one right triangle = 1/2 * 12 = 6 m.

So cos A = adjacent side /hypotenuse where A is the angle of inclination.

cos A= 6 / 8 = 0.75

m < A = 41.41 degrees.
