You have to find the reciprocal of the gradient - 1/2
And to do that just flip the sign and fraction:
-1/2
1/2
2/1

So the answer is,
Y = 2x + 11

What is the equation of a line with points -3,-11 and 2,4?​
const2013 [10]

Answer:

y=3x-2

Step-by-step explanation:

\frac{4-(-11)}{2-(-3)} =\frac{15}{5} =3

m=3 so using point-slope intercept form

y-y_{1}=m(x-x_{1} )

y-4=3(x-2)

       3x-6

+4        +4

y=3x-2

How long is the arc intersected by a central angle of startfraction pi over 2 endfraction radians in a circle with a radius of 4
Nimfa-mama [501]

<u>7.1 cm  long is the arc</u><u> intersected by a central angle .</u>

What is length of an arc?

  • The arc length of a circle can be calculated with the radius and central angle using the arc length formula.
  • Length of an Arc = θ × r, where θ is in radian. Length of an Arc = θ × (π/180) × r, where θ is in degree.

Given,

Central angle = π / 2

radius = 4.5 cm

we apply formula of length of arc.

length of the arc = angle ×  radius

                              = (π/2) × (4.5 cm)

Now put value of π = 3.14

length of the arc = (3.14 / 2) × (4.5) cm

                            = 7.065 cm ≈ 7.1 cm

Therefore, 7.1 cm  long is the arc intersected by a central angle .

5 STARS!!!
Ksivusya [100]

Since it is given that Boris takes x minutes to run 5 miles it means that Boris' speed will be given as: \frac{5}{x}.

Now, if Dylan runs slower than Boris and takes 12 more minutes to complete the 5 miles run, then that would mean that Dylan takes (x+12) minutes to complete the same run.

In this case we can see the Dylan's speed will be \frac{5}{x+12}.

Thus, the denominator represents the time Dylan takes to run 5 miles if he takes 12 minutes more than Boris.

Therefore, out of the given options, the second option is the correct option.
