A line containing the points (9, 1) and (5, 5) intersects the x -axis at what point?

Troyanec [42]

Answer:

It intersects the x-axis at x = 10

Step-by-step explanation:

Step 1: Find slope m

m = (5 - 1)/(5 - 9)

m = 4/-4

m = -1

y = -x + b

Step 2: Find b

5 = -5 + b

b = 10

Step 3: Rewrite equation

y = -x + 10

Step 4: Find x when y = 0

0 = -x + 10

-10 = -x

x = 10

So the graph crosses the x-axis at 10.

Last month you went on three hikes. one hike was2 3/4 miles long one was 1 1/2 miles long and was 3 3/4 miles long. in decimal h

creativ13 [48]

2 3/4 = 2.75

1 1/2 = 1.5

3 3.4 = 3.75

2.75 + 1.5 + 3.75 = 8

For f left parenthesis x right parenthesis equals StartRoot x EndRoot and g left parenthesis x right parenthesis equals 4 x plus

lara31 [8.8K]

Answer:

Step-by-step explanation:

Given that there are two functions f and g as

$f(x) = \sqrt{x} \\g(x) =4x+9$

We have to find the composition of functions.

Composition functions are calculated as the first function inside bracket and then the outside function of answer inside.

a) $fog= f{g(x)} =f(4x+9) = \sqrt{4x+9}$

b) $gof = g{f(x)} = g(\sqrt{x} )=4\sqrt{x} +9$

c) $fof = f(\sqrt{x} ) = \sqrt[4]{x}$

d) $gog = g(4x+9) = 4(4x+9)+9\\= 16x+45$
