Hey there! :)

3y + 2x = 12

To find the slope of this equation, we must turn this into slope-intercept form. Slope-intercept form is very simply : y = mx + b ; where m = slope, b = y-intercept.

Our first step should be to subtract 2x from both sides.

3y + 2x - 2x = 12 - 2x

Simplify.

3y = -2x + 12

Then, divide both sides by 3 so that we could get y by itself (which is what we call isolated in the math world).

3y ÷ 3 = (-2x + 12) ÷ 3

Simplify.

y = -2/3x + 4

So, our slope is -2/3!

An obtuse triangle has two angles 45 n 18 ,and a third unknown angle theta what's the value of the unknown angle

zlopas [31]

Answer:

An obtuse triangle has two angles 45 and 18. The value of the unknown angle is $117^{\circ}$

Solution:

Given that two angles of an obtuse triangle is 45 and 18.

Third angle is θ

We are asked to find the value of third unknown angle theta

According to angle sum property of triangle, sum of three angles of triangle is $180^{\circ}$

This means in our case sum of 45, 18 and θ should be $180^{\circ}$

$\begin{array}{l}{=>45+18+\theta=180} \\ {=>\theta=180-63=117^{\circ}}\end{array}$

Hence value of unknown third angle of an obtuse triangle is $117^{\circ}$

A town has a population of 8000 and grows at 3% every year. To the nearest tenth of a year, how long will it be until the popula

Alexxx [7]

Answer:

It will take approximately 34 years

Step-by-step explanation:

If a town population is 8000 and grows 3% annually.

How long will it take to reach 16300

growth is 16300 - 8000 = 8300

using simple interest formula

SI = (P × r × t)/100

8300 = (8000 × 3 × t)100

8300= (80 × 3)t

8300 = 240t

t = 8300/240

t ≈ 34 years to the nearest tenth
