Write an equation for a line that passes through (-1,4) and is parallel to 2y + 10x=-36

max2010maxim [7]

Hi there Brook!

First, you need to find the slope of this linear line, because if two lines are parallel they have the same exact slope.

2y + 10x = -36 <-- Subtract 10x on both sides
2y = -10x - 36 <-- Divide everything by 2
y = -5x - 18 <-- Your re-organized linear equation, with the slope of -5.

Now that you know the slope is -5, but not the y-intercept since the line is different, look at the coordinate you have. Since you know that an input of -1 makes an output of 4, you can create an equation:

4 = -5(-1) + b <-- Four equals the slope times the input, plus the y-intercept
4 = 5 + b
b = -1, since 5 + (-1) = 4.

So, now your final equation is y = -5x -1

You are one mile from the railroad station, and your train is due to leave in ten minutes. You have been walking at a steady rat

dybincka [34]

Answer:

x=1.818minutes

Step-by-step explanation:

3/60 miles per minute for walk

8/60 miles per minute for run

0.05x + 0.1333y=1

x+y=10

x=y-10

0.05(y-10) + 0.133333y = 1

0.05y-0.5+0.133333y=1

0.18333y=1.5

y=8.18minutes

x=10-8.18

x=1.818minutes

Liliana solved the equation below. When she tried to verify her answer, she realized she made an error.

leva [86]

Answer:

Step 3 of substracting 6 from both sides.

Step-by-step explanation:

We are given the following information in the question:

We are given the equation:

$\displaystyle\frac{1}{3}(x + 18) = 7$

Multiplying the constant term we get,

$\displaystyle\frac{1}{3}x + 6 = 7$

Subtracting 6 from both the sides we get,

$\displaystyle\frac{1}{3}x + 6-6 = 7-6\\\\\frac{1}{3}x = 1\\\\x = 3$

Liliana made a mistake in the step of subtracting 6 from both sides. She subtracted 6 from the left side bu added 6 on the right side instead of subtracting from the right side.

88 feet/second = 60 miles/hour. How many feet per second is 1 mile? (Hint: divide both side of the equation by the same amount.)

zalisa [80]

Answer:

1 mile/hour is equivalent to 1.47 feet/seconds

Step-by-step explanation:

Given

$88 ft/s= 60 miles/hr$

Required

Determine the equivalent of 1 mile/hour

$88\ ft/s= 60\ miles/hr$

Express 60 as 60 * 1

$88\ ft/s= 60 * 1\ mile/hr$

Divide both sides by 60

$\frac{88\ ft/s}{60}= \frac{60 * 1\ mile/hr}{60}$

$\frac{88\ ft/s}{60}= 1\ mile/hr$

Reorder

$1\ mile/hr = \frac{88\ ft/s}{60}$

Divide 88 by 60

$1\ mile/hr = 1.46666666667\ ft/s$

Approximate to 3 significant figures

$1\ mile/hr = 1.47\ ft/s$

Hence;

1 mile/hour is equivalent to 1.47 feet/seconds
