Answer:
Remainder is 44.
Step-by-step explanation:
Remainder theorem says that if f(x) is divided by the linear polynomial (x-a) , then remainder is f(a)
In given question , f(x) = x³ + 5x² -7x
linear polynomial is (x+4) = (x - (-4) )
so from remainder theorem , remainder = f(-4) = (-4)³ + 5 ( -4)² - 7(-4)
= -64 + 80+28=44
Hence Remainder is 44.
Answer:
x = 7
y = -2
Step-by-step explanation:
4x + 3y = 22 ---------------------(I)
5x - 4y = 43 ---------------------(II)
Multiply(I) by 4 and equation (II) by 3. And then add the equations
(I) * 4 16x + 12y = 88
(II) *3 <u>15x - 12y = 129</u> {Add & thus y will be eliminated}
31x = 217
x = 217/31
x = 7
Plug in the value of x in equation (I)
4*7 + 3y = 22
28 + 3y = 22
3y = 22 - 28
3y = -6
y = -6/3
y = -2

0.41666666666
Step-by-step explanation:
I used a calculator.
C. The Y value does not change because you are only reflecting over x= lines. After the first, it is (-3.5). Then (7, 5)
