The numbers are "x" and "y", therefore, we suggest this system of equations:
x-y=14
xy=1800
We can solve by substitution method.
x=14+y
(14+y)y=1800
14y+y²=1800
y²+14y-1800=0
Now, we solve this square equation:
y=[-14⁺₋√(196+7200)] / 2=(-14⁺₋86)/2
We have two solutions:
y₁=(-14-86)/2=-50 ⇒x=14+y=14-50=-36
y₂=(-14+86)/2=36 ⇒x=14+y=14+36=50
Answer: we have two solutions:
Solution1: The first number is -36 and the other number is -50
Soltuion2: The first number is 50 and the other number is 36
Answer:
((5*5) + (10-5) * (50/100)) ÷ 3 = 5
((4*4)+(17-8 *(1.378/2)) ÷ 3.445 = 5
Step-by-step explanation:
Answer:
The zeroes are at (-2, 0), (0, 0) and (2, 0).
The (0, 0) is a double root as the graph just touches the x axis at (0, 0).
The zero at (0, 0) is sometimes referred as x = 0 (multiplicity 2).
I think the duplicate roots are counted as 2 distinct roots but im not sure.
So the answer is either a or c.
Step-by-step explanation:
The zeroes are the points where the graph cuts the x axis.
Answer:
D. 20
Step-by-step explanation:
Since you are subtracting, you can add 4 and 1. The sum is 5. 20/4 is equal to 5 so R = 20.
