Answer:
No solution
Step-by-step explanation:
Given two equations are 2x+4y= -8 and 4x+8y= 5
These two lines are parallel They don't have a solution because they do not meet .
Multiply the first equation by 2 we get 4x+8y = -16
the other equation is 4x+8y= 5 clearly these two are parallel .
To prove by elimination method we have subtract those two equations we get 21≠0 which is not possible.
Therefore there is no solution to the given set of equation.
Answer:
Only 2 and -5 are roots. Any other number is not a root.
Step-by-step explanation:
The zeros of the function are the x-intercepts and are found by factoring the equations and solving for x using the zero product property.
The f(x) = (x2 - 4x + 4) (x2 + 3x - 10) = 0 can factor into
f(x) = (x -2)(x-2)(x+5)(x-2) = 0.
Set each factor equal to 0 and solve.
x - 2 = 0 so x = 2. This repeats twice.
x + 5 = 0 so x = -5.
So the zeros are 2, -5.
Answer:
3 out of 15
Step-by-step explanation:
Answer:
K is either 9 or 1
Step-by-step explanation:
Sqrt((0 - 3)² + (k - 5)²) = 5
Square both sides
(0 - 3)² + (k - 5)² = 5²
(0 - 3)² + (k - 5)² = 25
-3² + (k - 5)² = 25
9 + (k-5)(k-5) = 25
9 + k² - 5k - 5k + 25 - 25 = 0
k² - 10k +9 = 0
k² - 9k - k + 9 = 0
k(k - 9) - 1(k - 9) = 0
k - 1 = 0 ; k = 1
k - 9 = 9; k = 1
K = 9 or k = 1
K is either 9 or 1
