Helpp i got -4 am i correct?

Mathematics
1 answer:
Goryan [66]3 years ago
8 0

Answer:

-4

Step-by-step explanation:

Slope is rise over run:

m=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}

The table is a linear function, so any two points from the table would have a consistent slope.  

Pick two points and apply them to the formula:

(-4,-2) and (-2, -10)

m=\frac{-10+2}{-2+4}=\frac{-8}{2}=\boxed{-4}

The slope is -4.  Yes, your answer should be correct.

Please help this is hard math
Rainbow [258]

Answer:

y=-4x+2

Step-by-step explanation:

  • First we find the slope of the line AB passing through the point (2,0)
  • line AB is perpendicular to the line y=\frac{1}{4}x-3 , this equation is slope intercept for, which is y=mx+b so our m or slope is \frac{1}{4}
  • Since the slope of line AB is perpendicular to m=\frac{1}{4} then we use the equation slope of line1\times slopeofline2=-1 , so what do we multiply \frac{1}{4} by to get -1? -4 right, so that's the slope of line AB with the point (2,0)
  • Now line CD is parallel to line AB, that means it has the same slope as AB, so slope of CD is -4
  • So we make the equation y-y_1=m(x-x_1) so m= -4 and our point is (-1,6)
  • y-(6)=-4(x-(-1)\\y-6=-4x-4\\y=-4x-4+6\\y=-4x+2 thats the equation of line side CD

Olga is putting a border around her triangular flower bed. She has 20 feet of border material, which will fit perfectly around t
spayn [35]

Answer:

60 feet

Step-by-step explanation:

We know that a triangle has 3 sides, in this case we will call them a, b and c.

It tells us that everything is material, it measures 20, that is:

a + b + c = 20

They tell us that she wants to triple each side and to know how much material she would need in total. Then it would be:

border material need = 3 * a + 3 * b + 3 * c

common factor 3:

border material need = 3 * (a + b + c)

border material need = 3 * 20

border material need = 60

Which means that she needs a total of 60 feet of material.

A hotel wants to put a fence around a circular spa. The radius of the spa is feet. If the fence is built along the immediate edg
MariettaO [177]

For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:

P = 2 \pi*r

Where "r" represents the radius of the circle, in this case r = \frac {5} {\sqrt {2} -1}

Substituting in the perimeter equation we have:

P = 2 \pi * \frac {5} {\sqrt {2} -1}

Rationalizing we have:

P = \frac {2 \pi * 5 (\sqrt {2} +1)} {(\sqrt {2} -1) * (\sqrt {2} +1)}\\P = \frac {2 \pi*5 \sqrt {2} +2 \pi*5} {2-1}\\P = 10 \pi \sqrt {2} +10 \pi

Taking out common factor \pi:

P = (10 \sqrt {2} +10) \pi

Answer:

P = (10 \sqrt {2} +10) \pi\ feet

Option C
