Answer:
a=7.9
Step-by-step explanation:
2.25(a+1.3)=20.7 *Distribute (multiply) the 2.25 throughout the parenthesis
2.25a+2.925=20.7 *Subtract 2.925 from both sides
2.25a=17.775 *DIvide by 2.25
a=7.9
Answer:
1/243
Step-by-step explanation:
When you see this notation, it means plug in -1 for x in the function.
f(-1) = 3^((-1)-4)
f(-1) = 3^-5
f(-1) = 1/3^5
f(-1) = 1/243
ANSWER
4 roots.
EXPLANATION
The given polynomial function is
This is a fourth degree polynomial.
According to the Fundamental Theorem of Algebra, an nth degree polynomial has n roots.
This roots include both real and complex roots.
Also repeated roots or roots with multiplicity greater than one are counted as distinct.
Since the given polynomial function is a fourth degree polynomial, the Fundamental Theorem of Algebra, says that this polynomial has 4 roots.
Answer:
I believe that the missing value is 5, y=5
Step-by-step explanation:
1st since you can see in the ordered pair that 8 is in the x place that means 8 is the x value so what you can do is rewrite the equation to look like this: 5(8)-2y=30
2nd solve for y
5(8)-2y=30
40-2y=30
-40. -40 -subtract 40 on both side
-2y=-10
÷-2. ÷-2 -divide -2 on both sides
y=5
