this is the associative property of addition
Answer:
The domain is where is an integer.
Step-by-step explanation:
We see from the data given that the domain of T(a) takes both positive and negative integer values <em>( 8848 meters and -418 meters);</em> T(a) never gets decimal values<em> (and in real life thy won't be of much use because we are not looking for that much accuracy).</em>
So the appropriate <em>number type</em> for the domain of T(a) would be integers. And if you are interested, the domain is .
Answer:
Step-by-step explanation:
Look at the y-values as x-values are same for all tables.
<u>We see that:</u>
- Tables 1 and 5 - linear function as the differences are same.
- Tables 2 and 3 - exponential function as the ratios are same.
- Tables 4 and 6 - seem quadratic as there are repeat values showing the symmetry.
Hello,
To solve this question, a good method to use is creating an equation.
The number x being multiplied by 4 can be represented as 4x.
If this results in 25, we can create the equation:
4x = 25
To solve for x, you want to remove the coefficient of 4 from x, so we can divide by 4 on both sides (doing this we will only get x on the left side of the equation, which is what we are trying to solve for).
So, dividing by 4 on both sides, we have
(4x / 4) = (25 / 4)
x = 25/4
x = 25/4, which cannot be further simplified as a fraction. However, this can be represented by 6.25 in decimal form.
x = 25/4, or 6.25
Hope this helps!
