Answer:

B. They are perpendicular

Step-by-step explanation:

They fit the criteria for what you need of a set of perpendicular lines.

For this case, we have to define perpendicular lines:

m1 * m2 = -1

We have then:

m1 = \frac {1} {5}\\m2 = -5

Then, according to the definition we have:

(\frac {1} {5}) (- 5) = \frac {-5} {5} = -1

We observe that the definition is fulfilled, therefore, the lines are perpendicular.

Answer:

b. they are perpendicular

Find the equation of the graphed line.
Alex_Xolod [135]

example: the line is y = ax + b

The line go through 2 points ( -4 ; 0 ) and ( 0 ; -2 )

So:

  • -2 = 0a + b => b = -2
  • 0 = -4a + (-2) => a = 2/-4 = -1/2

The line is y = -1/2x - 2 ( i'm not sure)

Answer: a

Ok done. Thank to me :>

A model of a volcano has a height of 12 in. , and a diameter of 12 in. What is the approximate volume of the model? Use 3. 14 to
jenyasd209 [6]

The approximate volume of the model will be

v=452.33 inch^{2}

<h3 /><h3>What is the approximate volume of the model? </h3>

It is given that

Height of the volcano =12 inch

Diameter of the volcano= 12inch=r=6inch

So the volume of the model will be =

=\dfrac{1}{3\\} \pi \times r^{2} \times h

= \dfrac{1}{3} \pi \times (6)^{2} \times 12

v=452.33inch^{2}

Thus the approximate volume of the model will be  v=452.33 inch^{2}

Solve the following problem when -2 is outside an absolute value equation: -2|-2r-4|=-12
VMariaS [17]

-2|-2r-4|=-12

divide by -2

|-2r-4| = 6

we get a positive and negative solution

-2r-4 = 6     and -2r - 4 = -6

-add 4 to each side

-2r = 10         -2r = -2

divide by -2

r = -5    and r = 1


Answer r = -5 ,1

If 5²+m × 5⁷ =5¹⁵ ,find the value of m<br>please answer this question fast thank you!​
rewona [7]

Answer:

m = 6

Step-by-step explanation:

Here, we want to find the value of m

To do this, we use the indices addition property for multiplication

On the left hand side;

5^(2 + m + 7) = 5^15

5^(m + 9) = 5^15

since the bases are equal, we equate the powers

m + 9 = 15

m = 15-9

m = 6
