Answer:
The answer to your question is: k + 10
Step-by-step explanation:
x³ + 4x² - 7x + k divided by (x - 2)
Using synthetic division
1 4 - 7 k 2
2 12 10
1 6 5 k + 10
x² + 6x - 5 remainder = k + 10
Answer: 7/8
Step-by-step explanation: This is a substitution problem, from the expression x + ³/₄, where x = ¹/₈, we now replace or substitute for x and then solve the expression fractionally, the expression now becomes
¹/₈ + ³/₄
Now , find the l. c. m. of the denominator 8 and 4
1 + 6
= _____
8
= 7/8
NOTE: To get 1 and 6, you find out how many times 8 can go in the l. c. m. and later multiplied the number of times by the numerator which = 1.
And the number of times 4 can go in the l. c. m. (8) which is 2 times then multiplied by the numerator (3) = 6.
Adding 1 and 6 together gives 7/8.
Answer:
4.31
Step-by-step explanation:
Find the cube root of both sides of the equation.
= 
The cube root will cancel out the cubed in the variable.
v = 
Find the cube root of 80. I rounded to the nearest hundredth.
v = 4.31
For the first question, all you have to do is substitute the values. for example g(x)=-5x+2 becomes g(-1)=-5(-1)+2
