What is the slope of the line joining (8,8) and (12, 6)?

Anna71 [15]

Answer:

$\huge \boxed{ \boxed{ - \frac{1}{2} }}$

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

From the question we have

$m = \frac{6 - 8}{12 - 8} = - \frac{2}{4} = - \frac{1}{2} \\$

We have the final answer as

$- \frac{1}{2} \\$

Hope this helps you

If f(x) = x squared and g(x) = x - 4 what value is equivalent to (f•g)(10)

galina1969 [7]

Answer:

600

Step-by-step explanation:

note that (f • g) = f(x) × g(x)

f(x) × g(x) = x²(x - 4)

(f • g )(10) = 10²(10 - 4) = 100 × 6 = 600

The perimeter of a rectangle is 38 ft. The length is 9 ft longer than the width. Find the demensions. Write a system of linear e

nikdorinn [45]

P=38
P=2x+2y=2(x+y)
x=9+y

so
38=P=2(x+y)
38=2(x+y)
divide both sides by 2
19=x+y
x=9+y
19=9+y+y
19=9+2y
minus 9 both sides
10=2y
divide by 2
5=y
sub back
x=9+y
x=9+5
x=14

x=14
y=5
