Answer:

-1/8

Step-by-step explanation:

Perpendicular slopes are negative reciprocals

The slope of y=8x+5 is 8, because it is in slope intercept form: y=mx+b form, where m is the slope.

Negative:

8/1--> -8/1

Reciprocal:

Flip the numerator and denominator

-8/1--> -1/8

So, the perpendicular slope of 8 is -1/8

The measures of two sides of a triangle are 15 and 16. between what two numbers must the measure of the third side fall?

QveST [7]

If it is a right triangle and you given me adjacent and opposite the formula is
${r}^{2} = {x}^{2} + {y}^{2}$
third side = 21.93

if its not right triangle you need the angle to solve

Find the solution to the equation 4r + 2(r - 8) = 4(3 + r).

o-na [289]

Answer:

r = 14

Step-by-step explanation:

Use distributive property:

4r + 2r - 16 = 12 + 4r

Combine like terms:

6r - 16 = 12 + 4r

Isolate the variable:

6r = 28 + 4r

2r = 28

r = 14

Make c the subject:<br> x=-b+(b²-4ac) divided by 2a<br><br> The brackets mean square root

kipiarov [429]

$x=\dfrac{-b+\sqrt{b^2-4ac}}{2a}\\
2ax=-b+\sqrt{b^2-4ac}\\
\sqrt{b^2-4ac}=2ax+b\\
b^2-4ac=(2ax+b)^2\\
-4ac=4a^2x^2+4abx+b^2-b^2\\
-4ac=4a^2x^2+4abx\\
c=-ax^2-bx$
