Find the solution in slope-intercept form y+7=-3(x-1) and 3x+y=-4

Mathematics

Svetach [21]3 years ago

Answer:

The slope intercept form of both given equations is : y =  - 3 x - 4.

Step-by-step explanation:

Here, the given equations are:

y +7 = -3 ( x - 1 )

and 3 x + y = - 4

Now,the SLOPE INTERCEPT FORM of any given equation is given as:

y = m x + C : here, C = Y - intercept, m = Slope

Consider equation (1):

y +7 = -3 ( x - 1 )    ⇒ y + 8 = - 3 x  + 3

or, y = -3x + 3 - 7 = -3x - 4

 ⇒ y =  -3x  -4

Hence, the slope-intercept form of the given equation is y =  -3x  -4.

Consider equation (2):

3 x + y = - 4    ⇒ y  = -4  - 3 x

 ⇒ y =  -3 x  - 4

Hence, the slope-intercept form of the given equation is y =  -3x  -4.

Answer:

  • 127.32 yards diameter
  • 12,732.4 square yards area

Step-by-step explanation:

The diameter can be found from the circumference using the relation ...

  C = πd

  d = C/π = (400 yd)/π ≈ 127.32 yd . . . . diameter

The area is ...

  A = πr²

where the radius (r) is half the diameter.

  A = π(63.662 yd)² ≈ 12,732.4 yd² . . . . area

_____

<em>Additional comment</em>

We have used a full-precision value for pi. If you use 3.14, your answers will be different. Your diameter will be about 127.4 yards; your area about 12,738.9 yd².

Find the positive solution for c:<br><br> 8 2 + 15 2 = c 2
Scrat [10]

Answer:

15

Step-by-step explanation:

8² + 15² = c²

To find : Value of c

8² = 8 x 8 = 64

15² = 15 x 15 = 225

c² = 225

225 = 15 x 15 = 15²

So,

c² = 15²

c = 15
