Answer:
x= -2 is correct answer
Step-by-step explanation:
3(-2×-2)+13(-2)+14=0
3(4)+13(-2)+14=0
12+(-26)+14=0
12-26+14=0
12+14-26=0
26-26=0
0=0
Step-by-step explanation:
(5 – 5i) . (-3+5i)
=-15+25i+15i-25i²
=-25i²40i-15
I believe the answer is C
Answer:
slope = - 2 and y- intercept = 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x + 6 ← is in slope- intercept form
with slope m = - 2 and y- intercept c = 6
Answer:
The answer is 4 + 4 + 4 - 4 = 8
Step-by-step explanation:
The four fours problem is one of the problems given in the book "The Man Who Calculated" by Malba Tahan, a Brazilian-born professor of mathematical sciences.
There are many complicated problems in this book made with the intention of using logic to find a value.
The 4 fours problem is based on using these numbers and using any operation to result in the numbers 1 through 10.
