Answer:

Its perpendicular

Step-by-step explanation:

You can solve the equation to get x=-2.5 and y = -7.5 so they intersect there, but they intersect at 90 degrees so its perpendicular.

The sum of four consecutive integers is −46. What is the smallest of these integers?
Gwar [14]

Answer:The integers are -13, -12 and -11.

Step-by-step explanation:

Let the four numbers be n, n+1, n +2, and n+3

Therefore (n )+ (n+1 )+(n+2) + (n +3) = -46

4n + (1 +2+3) = -46

4n + 6= -46

Subtract 6 from both sides to get the value of n

4n +6 - 6= -46 -6

4n = -52

Divide both sides by 4

n = -52/4

n = -13

Therefore, n + 1 = -13 + 1= -12

n + 2= -13 + 2 = -11

The integers are -13, -12 and -11.

I hope this helps, please mark as brainliest.

The diagram below shows circle with radii OA
Finger [1]

Answer:

Length of arc AB = 4π

Step-by-step explanation:

Formula to get the arc length is given by,

Length of arc = \frac{\theta}{360}(2\pi r)

Here, θ = central angle subtended by the arc AB

r = Radius of the circle

By substituting the values in the formula,

Therefore, length of arc AB = \frac{120}{360}(2\pi )(6)

                                              = 40π

Makayla is moving and must rent a truck. There is an initial charge of $40 for the rental plus a fee of $3 per mile driven. Writ
Sergeeva-Olga [200]

Answer:

C(m) = $(40+3m)

Step-by-step explanation:

In this question, we are asked to write an equation representing the total cost of renting a truck by Makayla.

We proceed as follows;

Form the question, we can deduce that there is an initial cost of $40 and a rental fee of $3 per mile driven.

Now, we were made to know that she had driven m miles. We now calculate the rental fee for this m miles she has driven. Mathematically, we only need to find the product here. The rental fees for the m Miles traveled would be m * 3 = $3m

Now the total cost C(m) would be = $40 + $3m or simply C(m) = $(40+3m)
