Answer:

y = 2

Step-by-step explanation:

use slope formula:

(4 - y) / (3 - 10) = -2/7

4-y / -7 = -2 /7

cross-multiply:

7(4 - y) = (-7)(-2)

28 - 7y = 14

-7y = -14

y = 2

The map of a biking trail is drawn on a coordinate grid. The trail starts at P(−2, 2) and goes to Q(5, 2). It goes from Q to R(5
love history [14]

Answer:

The total length (in units) of the biking trail is 17 units.

Step-by-step explanation:

o find distance between points A(x¹, y¹) and B(x², y²), we use formula:

d = \sqrt{(x^{2}-x^{1})^{2}+(y^{2}-y^{1})^{2}}

The trail starts at P(−2, 2) and goes to Q(5, 2).

So, the distance PQ will be calculated as:

PQ = \sqrt{(5^{}-(-2)^{})^{2}+(2^{}-2^{})^{2}

PQ = \sqrt{(49^{}+0)

PQ = 7 units

Then the trail goes from Q(5, 2) to R(5, −5).

So, the distance QR will be calculated as:

QR = \sqrt{(x^{2}-x^{1})^{2}+(y^{2}-y^{1})^{2}}

QR = \sqrt{(5^{}-5^{})^{2}+(-5^{}-2^{})^{2}

QR = 7 units

And then from R(5, −5) to S(8, −5).

RS = \sqrt{(8^{}-5^{})^{2}+(-5^{}-(-5)^{})^{2}}

QR = 3 units

Hence, the total length of the biking trail is:

                               PQ + QR + QR = 7 + 7 + 3 = 17 units

Keywords: distance formula, length

Solve the inequality 12(1/2x-1/3)>8-2x
Setler [38]

Answer:

The answer is

<h2>x >  \frac{3}{2}</h2>

Step-by-step explanation:

<h3>12( \frac{1}{2} x -  \frac{1}{3} ) > 8 - 2x</h3>

<u>Expand the terms in the bracket</u>

That's

<h3>6x - 4 > 8 - 2x</h3>

Move - 2x to the left side of the inequality to make it positive

<h3>6x + 2x - 4 > 8 \\ 8x - 4 > 8</h3>

<u>Add 4 to both sides</u>

That's

<h3>8x - 4 + 4 > 8 + 4 \\ 8x > 12</h3>

<u>Divide both sides by 8</u>

<h3>\frac{8x}{8}  >  \frac{12}{8}</h3>

We have the final answer as

<h3>x >  \frac{3}{2}</h3>

Hope this helps you
