Please help me,I give up on this.i just don’t get it.

Stolb23 [73]

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

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

Im stuck on this question plz help

astra-53 [7]

Answer:

C) x = 20.8

Step-by-step explanation:

Since the line with the length equal to 6 forms a right angle on line x then we know it is perpendicular and bisects it.

Plug in the values: a^2 + b^2 = c^2

a^2 + 6^2 = 12^2

a^2 + 36 = 144

a^2 + 36 - 36 = 144 - 36

a^2 = 108

√a^2 = √108

a = √108

a = 10.3923048454

a = 1/2 x

2a = x

2(10.3923048454) = x

x = 20.7846096908

x = 20.8

I need help on this Pythagorean Theorem question would be nice if somebody helped quick

lina2011 [118]

Answer:

Step-by-step explanation:

5^2 + 5^2 = x^2

25 + 25 = x^2

50 = x^2

$\sqrt{50}$ = x, 5 $\sqrt{2}$

x = approximately 7.07
