Answer: 3x-y=2 and 3x-y=1 (First Answer Choice)

First you want to isolate the y. (Subtraction Property of Equality)

-y = -3x+2 -y = -3x + 1

Then, extract the negative from the y by dividing by -1. (Division Property of Equality and Distribute)

(-1)-y = (-1)(-3x + 2) (-1)-y = (-1)(-3x + 1)

y = 3x - 2 y = 3x - 1

Notice that if you do the steps for the other answer choices, you would end up with a negative slope, which is not presented in the picture. A negative slope goes up down and positive slip goes down up.

How can completing the square aid in solving quadratic functions?

Elden [556K]

Completing the squares tells us exactly what square root we will need to calculate our answer.

Using the formula below you can find these answers:
$A(x-h)^2 + K = 0
(x-5)^ 2 = - K/A
$

Does this make sense?

A pilot and co-pilot are performing a test run in a new airplane. The pilot is required to take off and fly in a straight path a

crimeas [40]

Using the slope concept, it is found that:

The minimum horizontal distance is of 14,281.5 feet.

The maximum horizontal distance is of 15,398.6 feet.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change</u>.

It's also the tangent of the angle of depression.

In this problem, the vertical change is the altitude of 10,000 feet.

The minimum horizontal distance is with an angle of 35º, hence:

$\tan{35^{\circ}} = \frac{10000}{d}$

$d = \frac{10000}{\tan{35^{\circ}}}$

$d = 14281.5$

The maximum horizontal distance is with an angle of 33º, hence:

$\tan{33^{\circ}} = \frac{10000}{d}$

$d = \frac{10000}{\tan{33^{\circ}}}$

$d = 15398.6$

7 times what equals 1?

Arturiano [62]

For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
Doing the multiplication we have:
$(7) (x) = 1
$
From here, we clear the value of x.
We have then:
$x = \frac{1}{7} 
$
Therefore, we have:
$(7) ( \frac{1}{7} ) = 1
$
Answer:
7 times 1/7 equals 1
