Ok, so to solve this, you have to have the equations in standard form, which is:

y=mx+b

where m is the slope of the line

So, for the first equation, the slope is 4

For the second equation, you have to rearrange it so it's in standard form.

-15x+3y=-45

Begin to isolate y by performing the opposite operation of adding 15x on both sides of the equation

The 15x will cross out on the left

-15x + 15x = 0x = 0

The result on the right will be 15x - 45

3y = 15x - 45

To completely isolate y, perform the opposite operation by dividing 3 on both sides of the equation by 3.

When you do that, divide each term by 3

The 3's on the left will cross out

3y ÷ 3 = 1y = y

15x ÷ 3 = 5x

-45 ÷ 3 = -15

y = 5x-15

So, the slope of the line is 5

What is the area of the triangle?<br> 9 4 12
LUCKY_DIMON [66]

Answer:

  13.636

Step-by-step explanation:

The area can be found using Heron's formula:

  A = √(s(s-a)(s-b)(s-c))

where s=(a+b+c)/2.

For the given triangle, ...

  a=9, b=4, c=12, s=(9+4+12)/2 = 12.5

  A = √(12.5(3.5)(8.5)(0.5)) = √185.9375 ≈ 13.636

The area of the triangle is about 13.636 square units.

A temperature of –25°c is equivalent to:<br> a. 248 k.<br> b. 25 k.<br> c. –25 k.<br> d. 298 k.
SpyIntel [72]

The temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15:

T(K) = T(°C) + 273.15;

So, T(K) = -25 + 273.15;

T(K) = 248.15;

The correct answer is a.
