There are four values (I think) because the graph of the function f intersects y=3 four times.
Remember f(x) = y

A rectangular heptagon is measuring 26 mm and is divided by 7 congruent triangles. Each triangle has a height of 27 mm. What is

alina1380 [7]

Answer:

2,457 mm^2

Step-by-step explanation:

The dimensions of each of the triangles in terms of their bases and heights will be;

26 mm by 27 mm

Mathematically, the area of one of the triangles will be ;

1/2 * base * height

= 1/2 * 26 * 27 = 351 mm^2

So the area of the heptagon is the sum of the areas of all of the triangles

mathematically, that would be;

351 * 7 = 2,457 mm^2

Answer:

$y = -\frac{4}{5} x - \frac{14}{5}$
$y = \frac{5}{4} x -11$

Step-by-step explanation:

Given line ;

$y = \frac{5}{4} x -3\\\\m = slope\\m = \frac{5}{4}$

1. Perpendicular and passes through (4,-6)

$m_1 = \frac{5}{4} \\\\m_2 = \frac{-1}{m_1} \\\\m_2 = \frac{-1}{\frac{5}{4} } \\\\m_2 = -\frac{4}{5} \\\\(4,-6)=(x ,y)\\$

Substitute the values above into slope intercept form ; y=mx+b and solve for b.

$y =mx+b\\\\-6 = -\frac{4}{5} (4) + b\\\\-6 = -\frac{16}{5} + b\\\\-6 + \frac{16}{5} = b\\\\-\frac{14}{5} = b\\\\b = -\frac{14}{5}\\\\m = - \frac{4}{5}$

Substitute new values into ; y =mx+b.

$y = -\frac{4}{5} (x)- (\frac{14}{5} )\\\\y = -\frac{4}{5} x - \frac{14}{5}$

2.Parallel and passes through (4,-6)

$m = \frac{5}{4} \\\\(4,-6)=(x_1,y_1)$

Substitute values into point slope form and simplify

$y-y_1=m(x-x_1)\\\\y - (-6) = \frac{5}{4} (x -4)\\\\y+6 = \frac{5}{4} x -5\\\\y = \frac{5}{4} x -5-6\\\\y = \frac{5}{4} x -11$
