Answer:

y - 1 = -1 * (x + 2) < point-slope form

Step-by-step explanation:

y-y₁=m(x-x₁) then I just inserted the following numbers to fit the formula. I hope this helps!

Two trains left the station traveling in opposite directions. The distance Train A traveled is modeled by the function d(t)=81t

stira [4]

Answer:

Option A - The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.

Step-by-step explanation:

Given : The distance Train A traveled is modeled by the function $d(t)=81t$

where d represents distance in miles and t represents time in hours.

To find : How does the distance Train A traveled in 1 hour compare to the distance Train B traveled in 1 hour?

Solution :

Distance traveled by Train A in 1 hour is

$d(t)=81t$

$d(t)=81(1)=81$

Distance traveled by Train B in 1 hour is

$d(t)=81t$

$d(t)=81(1)=81$

or for B, we have 324 miles in 4 hours. If that is at a constant speed, it travels 324/4 = 81 miles in one hour

Therefore, The distance Train A traveled in 1 h is equal to the distance Train B traveled in 1 h.

Hence, Option A is correct.

Graph 14x+34y=1 pretty please with a cherry on top!Also thank-you

Svetlanka [38]

To make it much easier, it should be converted to the slope-intercept form
y = mx + b

To do so, 14x + 34y = 1 turns to:
34y = -14x + 1

Divide both sides by 34:
$\frac{34y}{34} = \frac{-14}{34} x + \frac{1}{34}$
Simplified:
$y = \frac{-7}{17} x + \frac{1}{34}$

Answer: $y = -\frac{7}{17} x + \frac{1}{34}$
Here is the graph:

Please helpp quick! i have no idea what the answer is

aleksley [76]

Answer:

Step-by-step explanation:

point-slope equation is y-y1=m(x-x1)

y1=2

x1=6

m=(-5/7)

so the equation is y-2=-5/7(x-6)

hope this helps :3

Help me with solving multi-step equations...13x + 2 = 4x + 38

svet-max [94.6K]

1 Subtract 22 from both sides
13x=4x+38-213x=4x+38−2

2 Simplify 4x+38-24x+38−2 to 4x+364x+36
13x=4x+3613x=4x+36

3 Subtract 4x4x from both sides
13x-4x=3613x−4x=36

4 Simplify 13x-4x13x−4x to 9x9x
9x=369x=36

5 Divide both sides by 99
x=\frac{36}{9}x=
9

36

6 Simplify \frac{36}{9}
