<span><span>x = x^2 - 30
or
x^2 - x - 30 = 0
Factors to
(x-6)(x+5) = 0
x = +6 is the positive number</span></span>
5u - (-20u) - u - 18u + (-11u) = 10
5u + 20u - u - 18u - 11u = 10
-5u = 10
-5(-2) = 10
So, in conclusion, X, is equal to -2.
Answer:
135 meters
Step-by-step explanation:
h = 60t - 5t²
t is in seconds and it says to find out the height after 3 seconds
Sub the value '3' into 't'
h = 60(3) - 5(3)²
h = 180 - 5(9)
h = 180 - 45
h = 135 m
Answer:
- 0.5
Step-by-step explanation:
Slope = y2 - y1 /x2 - x1
Given
x1 = 8
y1 = 8
x2 = 12
y2 = 6
Slope = 6 - 8 /12 - 8
= -2/4
= - 1/2
= - 0.5
