determine weather the point is a solution of the linear inequality show work
Answer:
Not a solution.
Step-by-step explanation:
4 < 2(7) - 15
4 < 14-15
4 < -1
Answer:
not a solution
Step-by-step explanation:
Substitute the x- coordinate of the point into the right side of the inequality and compare the result to the left side, that is
2(7) - 15 = 14 - 15 = - 1
Is 4 < - 1 ← no 4 > - 1
Thus (7, 4 ) is not a solution of the inequality

The graph that shows the solutions to the inequality is the last graph.
How to solve the given inequality?
Here we have the inequality:
-3.55g ≤ -28.4
To solve this, we need to isolate g, we can divide both sides by -3.55
g ≤ -28.4/-3.55 = 8
g ≤ 8
Then we must have a black dot at x = 8, and we shade the region to the left of it, meaning that the correct graph is the last one.

Write an inequality for the graph below
Answer:
y > -1/4x + 4
Step-by-step explanation:
First find the equation of the line itself, which is y = -1/4x + 4, then determine if graph shades above the line or below the line. If it shades above which is true in this case, it will be greater than. If it shades below which does not occur in this case, it will be less than. Because the line is dashed and not solid, it will just be greater than or less than.
Therefore y = -1/4x + 4 → y > -1/4x + 4 [Shades above the line, line is dashed].

Answer: B. Brianna’s age is 5 less than 3 times Molly age.
Step-by-step explanation:
We are informed that the expression below represents Brianna’s age in
terms of m, Molly’s age.
3m − 5.
This shows that 3m simply means that 3 times of Molly's age while the -5 represent less than 5. This will now be:
Brianna’s age is 5 less than 3 times Molly age.

) A gas station owner finds that for every penny increase in the price of gasoline, she sells 1516 fewer gallons of gas per week. How much more or less gas will she sell if she raises the price by 10 cents per gallon? If she decreases the price by 2 cents per gallon?
Answer:
a) 15160 gallons
b) 3032 gallons
Step-by-step explanation:
Given that for every penny increase in the price of gasoline there is a decrease of 1516 gallons sold per week
a) when she raises the price by 10 cents per gallon
There will be a decrease of ( 1516 * 10 ) gallons sold per week i.e. = 15160 gallons
b) when she decrease the price by 2 cents per gallon
There will be an increase ( 2 * 1516 ) gallons sold per week i.e. = 3032 gallons

Can sides of a triangle have lengths 3,4,9
Answer:
yes
Step-by-step explanation:
No, the lengths 3, 4, and 9 cannot form the sides of a triangle.
What is Triangle Inequality?The triangle inequality is a fundamental geometric principle that states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
We have sides as 3, 4 and 9.
For a triangle to be valid, the sum of the lengths of any two sides must be greater than the length of the third side.
In this case, let's check if this condition is satisfied:
3 + 4 = 7
7 is less than 9
Therefore, these lengths do not satisfy the triangle inequality theorem, and a triangle cannot be formed with side lengths 3, 4, and 9.
