To find vector b, substitute the given value of a into the equation and solve for b. The vector b is (-23).
To find vector b, we need to solve the equation 3a - 2b = 8 (-17). Given that a = 2 (-3), we can substitute it into the equation:
3(2) - 2b = 8 (-17)
6 - 2b = 8 (-17)
-2b = 2 (-23)
b = (-2) / (-2/23)
b = -23
So, the column vector b is:
b = (-23)

Answer:
11/-30 Hope this helped :)
Step-by-step explanation:
15x + 4 = -1 1/2
15x = -5 1/2
x = 11/-2*1/15
x = - 11/-30

Given the polynomial function
The integer zeros should be divisors of free term -42.
The divisors of -42 are:
If some of these number is zero of f(x), then f takes 0 value at this point.
Check them:
Since the third degree polynomial function may have only 3 zeros, then you can end this process and state that zeros are 2, 3 and 7, because f(2)=0, f(3)=0 and f(7)=0.
Answer: correct choice is C
Answer: Zeroes are,
7, 3, 2
Step-by-step explanation:
Here, the given cubic equation,
Since, at x = 7,
Thus, 7 is one of the zeroes of f(x),
⇒ x - 7 is a factor of f(x),
By the long division method ( shown below ),
We found that,
( By middle term splitting )
For finding the zeroes, f(x) = 0,
⇒ x -7 =0 or x-3 =0 or x-2 =0
⇒ x = 7 or 3 or 2
Answer:
m∠A = 60°
Step-by-step explanation:
Complementary Angles add up to 90°
Step 1: Set up equation
8x + 20 + 7x - 5 = 90
Step 2: Solve for x
15x + 15 = 90
15x = 75
x = 5
Step 3: Find m∠A
m∠A = 8x + 20
m∠A = 8(5) + 20
m∠A = 40 + 20
m∠A = 60°
