Answer:
Question 7. -2 8. 3/2
Step-by-step explanation:
Answer:
Beto and Mark
Step-by-step explanation:
When you simplify Beto's equation, you get 0=5 which is inncorrect. 5 does not equal 0 so there are no solutions. When you simplify Mark's equation, you get 6=2 which is also inncorrect. 6 can not equal 2. If you solve the other 2 equations you get answers that can work.
Answer:
x = ± 6
Step-by-step explanation:
Given
x² - 72 = 0 ( add 72 to both sides )
x² = 72 ( take the square root of both sides )
x = ± = ± = ± 6
I think you should try your best and just never get but just always keep trying because if you give up that means you're not track so just keep trying and get it right.
How many zeros does the function f(x) = 3x12 − 17x8 + 11x4 − 6x + 23 have?
<span>Answer: the third option (12 zeroes..). </span>
<span>Use ^ to denote an exponent.. </span>
<span>f(x) = 3x^12 - 17x^8 + 11x^4 - 6x + 23.. </span>
<span>We know from that fact that the number of zeroes (real or complex) in a polynomial is the same as the degree of the polynomial.. </span>
<span>The degree is the greatest/highest power of the terms, which in this case is 12 (since 12 is the greatest exponent..).. </span>
<span>The degree is 12, thus it means there are 12 zeroes.. </span>
