Answer:
t = 9
Step-by-step explanation:
Step 1:
- t = 9 ( t - 10 ) Equation
Step 2:
- t = 9t - 90 Multiply
Step 3:
- t + 90 = 9t Add 90 on both sides
Step 4:
90 = 10t Add t on both sides
Step 5:
t = 90 ÷ 10 Divide
Answer:
t = 9

Answer:
A. 4
B. 1
Step-by-step explanation:
The degree of a one-variable polynomial is the largest exponent of the variable.
__
<h3>A.</h3>
For f(x) = x^4 -3x^2 +2 and g(x) = 2x^4 -6x^2 +2x -1, the sum f(x) +a·g(x) will be ...
(x^4 -3x^2 +2) +a(2x^4 -6x^2 +2x -1)
= (1 +2a)x^4 +(-3-6a)x^2 +2ax -a
The term with the largest exponent is (1 +2a)x^4, which has degree 4. This term will be non-zero for a ≠ -1/2.
The largest possible degree of f+ag is 4.
__
<h3>B.</h3>
The polynomial sum is ...
f+bg = (1 +2b)x^4 +(-3-6b)x^2 +2bx -b
When b = -1/2, the first two terms disappear and the sum becomes ...
f+bg = -x +1/2 . . . . . . a polynomial of degree 1
The smallest possible degree of f+bg is 1.
I believe that it would be 17.000000000 (17/20) I do not know if this is right, but I tried haha
(50x100):40=125
answer:125
