What is the equation of the line that passes through the point ( − 4 , 8 )and has a slope of − 1/4
JulsSmile [24]

Answer:

y = -1/4x + 7

Step-by-step explanation:

Plug in the point and slope into y = mx + b, and solve for b:

y = mx + b

8 = -1/4(-4) + b

8 = 1 + b

7 = b

Plug in the slope and b into y = mx + b:

y = mx + b

y = -1/4x + 7

So, the equation of the line is y = -1/4x + 7

A 25-year old woman burns 200−20t cal/hr while walking on her treadmill. Her caloric intake from drinking Gatorade is 110t calor
marin [14]

The net decrease in calories after walking for 5 hours is 50 calorie.

According to the statement

we have given that the

A 25-year old woman burns 200−20t cal/hr and Her caloric intake from drinking Gatorade is 110t calories during the t hour.

And we have to find the net decrease in calories after walking for 5 hours.

So, For this purpose,

We know that the

calories burns in one hour = 200−20t

calories burns in 5 hours = 5(200−20t)

calories burns in 5 hours = 1000 - 100t

Now,

Calorie intake in t hours = 110t

And

net decrease in calories after walking for 5 hours =  100t - 1000 + 110t

put t is 5 then

net decrease in calories after walking for 5 hours = 210(5) - 1000

net decrease is 50 cal.

So, The net decrease in calories after walking for 5 hours is 50 calorie.

Which statements are true about the circle shown?
CaHeK987 [17]

Answer:

Among the five statements,statement 1 and 4 are true for the circle shown.

Step-by-step explanation:

Given:

An image is attached here.

A circle with radius = 15.4 m

We ave to find the diameter,circumference and relationship between the two.

Formula to be used:

⇒ Diameter of a circle = 2r        

⇒ Circumference = 2πr

Lets find the values.

  • Diameter = 2r=2(15.4) = 30.8 m
  • Circumference = 2\pi r =2(3.14)(15.4)=96.7 m
  • Relationship = \frac{circumference}{diameter} = \frac{96.7}{6} =3.1

We can say that a little more than 3 diameters could be wrapped around the circle.

From the drop down our choices are.

  • The diameter of the circle is 30.8 m.
  • The approximate circumference of the circle ,rounded to the nearest tenth is 96.7 m.

Option 1 and 4 are the right choices.

(x^2–x–4)multiplied by(x–5)
Sergio [31]

(x-5)(x^2-x-4) =x^3-6x^2+x+20

Step-by-step explanation:

Given polynomials are:

x^2-x-4\\and\\x-5

Both polynomials have to be multiplied. We will use distributive property for the said purpose

So,

(x-5)(x^2-x-4)\\=x(x^2-x-4)-5(x^2-x-4)\\=x^3-x^2-4x-5x^2+5x+20

Combining alike terms

=x^3-x^2-5x^2-4x+5x+20\\=x^3-6x^2+x+20

Hence,

(x-5)(x^2-x-4) =x^3-6x^2+x+20
