Answer:

x-intercept is (-4,0) and the y-intercept is (0,-2

Step-by-step explanation:

There are 2 ways to find the y-intercept. One way is to put the equation in slope-intercept form. However, there is a more efficient way as well.

Another way to do it is to plug 0 in for x and y. The x-intercept will have the coordinate of (x,0). So to find the x-intercept you can plug in 0 for y and solve for x. To find the y-intercept do the opposite and plug 0 in for x.

So, first, plug 0 in for y

x+2(0)=-4
x+0=-4
x=-4

Then plug in 0 for x

0+2y=-4
2y=-4
y=-2

Therefore, the x-intercept is (-4,0) and the y-intercept is (0,-2).

Step-by-step explanation:

ok so as u know the angles of a triangle add up to 180.

So we will be using that for help.

S+R+T=180

12x+13x+12x-4+2-3=180

37x-5=180

37x=185

x=5

Now we will plug in the value for x to find each angle

S= 13(5)-4

=61

T=12(5)-3

=57

R=12(5)+2

=62

Hope this helped:)

Answer:

(2) 2,640 ft

Step-by-step explanation:

I'm going to assume that in this question, you are walking 1 full circle around the reservoir. That would mean you need to calculate the circumference of the circular reservoir.

The circumference formula is:

C = ⫪d

C stands for Circumference

d stands for diameter

I will use 22/7 instead of pi, so the formula looks more like this:

C = (22/7)(d)

The diameter is 840 feet, so we will substitute the variable d with 840:

C = (22/7)(840)

You can plug this part into the calculator, but by hand, it'll look something like this:

(22/7)*840 = (22*840)/7

18,480/7 = 2.640

Hope it helps (●'◡'●)
