The equation of the line which is perpendicular to 3x - y = 10 is y = -(1/3) x + c. Then the correct option is B.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The line that is perpendicular to 3x - y = 10.

The equation can be written as

y = 3x - 10

Then the slope of the line will be

m₁ = 3

Let m₂ be the slope of the second line.

The product of the slope of the perpendicular lines is a negative one.

m₁m₂ = -1

 3m₂ = -1

   m₂ = -1/3

Then the equation of the perpendicular line will be

       y = - (1/3)x + c

     3y = -x + c

x + 3y = c

where c is the constant.

Thus, the correct option is B.

−6x+14&lt;−28 OR 9x+15≤−12
Serhud [2]

Answer:x>7 or x ≤ -3

Solving the 1st inequality

-6x +14 < -28 --------------- (Collect like terms)

-6x < -28 - 14

-6x < - 42 -------------------- (Divide both sides by -6)

Note: If you decide an inequality expression by a negative value, the inequality sign changes)

-6x/-6 > -42/-6

x > 7

Solving the 2nd inequality

9x + 15 ≤ −12 ----------- (Collect like terms)

9x ≤ −12 - 15

9x ≤ −27 ------------------(Divide both sides by 9)

9

9x/9 ≤ −27/9

x ≤ -3

Bring both results together, we get

x>7 or x ≤ -3

The final result is complex (i.e. can't be combined together).

If you roll a dice three times what is the probability of rolling an odd number each time
olasank [31]

Answer:

3/6

Step-by-step explanation:

there are 6 sides: 3 odd and 3 even numbers

if you need to find the probability of rolling an odd number, take the number of odd possibilities and form a fraction with the number of total sides, 6.

so, 3/6 Or 1/2

All the 5th graders at Lincoln Elementary School will go on a field trip to the science museum. Counting all the children, teach
user100 [1]

The answer must be a whole number because for example how are you suppose to fit half a child on a bus that can hold 44 people when it already holds that amount.

It will always be a whole number because if there are several left over students they will be put in another bus with more empty seats.
