8 0

Answer:

221 minutes

Step-by-step explanation:

52 divided by 20 would be 2.6 then you take the 85 and mulitpy it by 2.6 because 52 is 2.6 times more than 20. so 85 times 2.6 would be 221 minutes.

Write an equation of the line passing through the given points.
ANEK [815]

Answer:

The equation of the line passing through the given points.

(1,-5) and (-4,5) is

y=-2x-3

Step-by-step explanation:

Given:  

Let,  

point A( x₁ , y₁) ≡ ( 1 ,-5)

point B( x₂ , y₂ )≡  (-4 , 5)

To Find:  

Equation of Line AB =?  

Solution:  

Equation of a line passing through a points A( x₁ , y₁) and point B( x₂ , y₂ ) is given by the formula Two -Point Form,  

(y-y_{1})=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\times (x-x_{1})

Now on substituting the slope and point A( x₁ , y₁) ≡ ( 1 ,-5) and B( x₂ , y₂ )≡  (-4 , 5) we get

y-(-5)=\frac{5--5}{-4-1}\times (x-1)\\ \\y+5=\frac{10}{-5}(x-1)\\ \\y+5=-2(x-1)\\y+5=-2x+2 ......Applying\ Distributive\ property\\\\y=-2x+2-5\\\\y=-2x-3....Which\ is\ required

The equation of the line passing through the given points.

(1,-5) and (-4,5) is

y=-2x-3

4x-2=-13 solve for x
tigry1 [53]

Answer:

x = -11/4

Step-by-step explanation:

4x - 2 = -13

(add 2 on both sides)

4x - 2 + 2 = -13 + 2

4x = -11

(Divide 4 on both sides)

4/4x = -11/4

x = -11/4
