Tell whether or not the value is a solution to the inequality

Answers

Answer 1

Answer:

Answer:

Yes, n = -2.9 is a solution to the given inequality.

Step-by-step explanation:

To determine if n = -2.9 is a solution to the inequality 10.4 ≥ -2n + 4.6, substitute the value of n into the inequality.

10.4 ≥ -2(-2.9) + 4.6

10.4 ≥ 5.8 + 4.6

10.4 ≥ 10.4

Since the last line of the inequality states that 10.4 is greater than or equal to 10.4, which is true, this means that the original inequality holds true when n = -2.9.

So, n = -2.9 is a valid solution to the inequality 10.4 ≥ -2n + 4.6.

What is the solution set of the given equation?
4y - 6y + 9y = -2

Answers

Answer:

$y=-(2)/(7)$

Step-by-step explanation:

Given: $4y-6y+9y=-2$

To find: The solution set of the equation.

Solution:

We have, $4y-6y+9y=-2$ , and we need to find the solution set.

Now, we know that a solution set is any value of a variable in an equation which satisfies the equation. So, we need to find the value of variable, y in the given equation.

So, we have

$4y-6y+9y=-2$

$\implies 13y-6y=-2$

$\implies 7y=-2$

$y=-(2)/(7)$

Hence, the solution set of the equation is $y=-(2)/(7)$

4y - 6y + 9y = -2
-2y + 9y = -2
7y = -2
7 7
y = ⁻²/₇

The Mathalot Company makes and sells textbooks. They have one linear function that represents the cost of producing textbooks and another linear function that models how much income they get from those textbooks. Describe the key features that would determine if these linear functions ever intercepted.

Answers

The question is asking to explain or described the key features that would determine if the linear functions is ever intercepted base on the said equation and the function, I would say that the answer would be If two linear equations have different slopes, and are in the same plane, they WILL intersect at ONE point (they will have a unique solution).
