Answer:
They do form a proportion.
Step-by-step explanation:
To determine whether the two rates form a proportion, you can set up a proportion and check if the cross-products are equal.
The two rates you have are:
Rate 1: 7 inches in 9 hours
Rate 2: 42 inches in 54 hours
You can set up a proportion like this:
Rate 1 (inches per hour) / Rate 2 (inches per hour) = Time 1 (hours) / Time 2 (hours)
So, it becomes:
(7 inches / 9 hours) / (42 inches / 54 hours)
Now, let's calculate these fractions:
Rate 1 (inches pr hour) = (7 inches / 9 hours) ≈ 0.7778 inches per hour (rounded to 4 decimal places)
Rate 2 (inches per hour) = (42 inches / 54 hours) ≈ 0.7778 inches per hour (rounded to 4 decimal places)
Now, compare the two rates (rounded to 4 decimal places):
Rate 1 ≈ 0.7778 inches per hour
Rate 2 ≈ 0.7778 inches per hour
Since both rates are approximately equal to 0.7778 inches per hour, they do form a proportion. When two rates are in proportion, their ratios are equal, which is the case here.

Answer:
Coordinate geometry is one of the most important and exciting ideas of mathematics. In particular it is central to the mathematics students meet at school. It provides a connection between algebra and geometry through graphs of lines and curves. This enables geometric problems to be solved algebraically and provides geometric insights into algebra.
The invention of calculus was an extremely important development in mathematics that enabled mathematicians and physicists to model the real world in ways that was previously impossible. It brought together nearly all of algebra and geometry using the coordinate plane. The invention of calculus depended on the development of coordinate geometry.

Answer:
Option (a) is correct.
Step-by-step explanation:
Given :A function has real zeros at x = −10 and x = −6 .
We have to find the function that has real zeros at x = −10 and x = −6.
Consider real zeros at x = −10 and x = −6.
x = - 10 ⇒ x + 10 = 0
x = - 6 ⇒ x + 6 = 0
Multiply both zeroes, we have,
Apply Distributive rule,
we have,
Simplify, we have,
Thus,
Option (a) is correct.

Answer:
Not a solution
Step-by-step explanation:
To determine if a pair of coordinates is the solution to an equation, just plug it in.
Given that the equation is:
y = 19x - 2
And the coordinates they give us to evaluate:
(6, 4)
Plug the coordinates in:
y = 19x - 2
4 = 19(6) - 2
4 = 114 - 2
4 = 112
4 ≠ 112
4 is not equal to 112. Therefore this pair is not the solution.
Answer: No, it's not a solution.
Explanation
The point (6,4) tells us that x = 6 and y = 4 pair up together.
Plug those values into the equation. Simplify both sides as much as possible (use PEMDAS). If we get the same thing on both sides, then that point is a solution to the equation.
y = 19x - 2
4 = 19*6 - 2
4 = 114 - 2
4 = 112
We get different values on each side. Therefore, the point (6,4) is not a solution to the equation.
Another approach you could do is graph the equation using a tool like Desmos. GeoGebra works as well. The point (6,4) is not on the diagonal line. Check out the diagram below to see what I mean.
