Answer:
(x-rooot1)(x-root2)
Step-by-step explanation:
a quadratic ax²+bx+c=0 can be factor as those 2 pharanthesis
(x-rooot1) (x-root2)=0
and you can find the roots by making each parenthesis equal to 0 because of the zero product rule
x-root1 = 0, x=root1
x-root2 =0, x=root2
<span>The three equations can be written as 1) y = 2x - 5 ; 2) y = 2x - 3 and ;3) y = 2x + 5. Now, the slope can be found by slop intercept form of linear equation i.e. y = mx+b where m is the slope. From the above equations, we can see that all the the three have the same slope i.e. m = 2.</span>
Answer:
1 minute and 12 seconds is 2 % of an hour.
Step-by-step explanation:
Answer:
First part = 2.
Time to land = 6 seconds.
Step-by-step explanation:
The object is at h = 0 when it land so
-5x^2 + 20x + 60 = 0
-5(x^2 - 4x) = -60
-5[(x - 2)^2 - 4] = -60
(x - 2)^2 - 4 = -60/-5 = 12
(x - 2)^2 = 16.
Solving the above:
Take the square root of both sides:
x - 2 = 4
x = 2 + 4
x = 6 seconds
3n -10 ≥ 2
Add 10 to each side:
3n ≥ 12
Divide both sides by 3:
n ≥12/3
n≥4
The dot would be solid and located on the number 4, with the line and arrow moving/ pointing to the right.
1. n >2
2. n≤3
3. n<4
4. n≥5
