answer : -1 welcome
Step-by-step explanation:
4+-5 equals -1
Answer:
Step 1: Make sure the bottom numbers (the denominators) are the same
Step 2: Add the top numbers (the numerators), put that answer over the denominator
Step 3: Simplify the fraction (if needed)
Step-by-step explanation:
To solve this problem, all you need to do is make a standard graphing equation. The first step is finding mode using two points from the table. We'll use (1, 70) and (2, 90).

From the work, we've found that the
slope of this equation is
20.
Next, we need to finish writing the equation and plug in the coordinates to solve for the y-intercept.

Now we have all the information we need to write our equation, which is:
y = 20x+50Hope this helps!
Answer:
-27a³b⁶+ 8a⁹b¹²
Step-by-step explanation:
In the expression above -27 is a perfect cube of -3, 8 is a perfect cube of 2.
The exponents of a and b in both terms in the expression are divisible by 3.
The cube root of x, that is ∛xⁿ=x∧(n/3) where n is an integer.
