8(10-K) = 2k
mutiply the bracket by 8
(8)(10)= 80
(8)(-k)= -8k
80-8k= 2k
move -8k to the other side
sign changes from -8k to +8k
80-8k+8k= 2k+8k
80= 2k+8k
80= 10k
divide by 10 for both sides
80/10= 10k/10
k= 8
Answer: k= 8
Answer:
The answer is option 1.
Step-by-step explanation:
In order to find the equation, you have to apply Discriminant Law, D = b² - 4ac. When D < 0, the equation has no real roots (no x-intercept). When D = 0, it has 2 and equal roots (1 x-intercept). When D > 0, it has 2 distinct roots (2 x-intercept).
Option 1,
Option 2,
Option 3,
Option 4,
As you look at the graph, the curve does not meet x-axis so the discriminant must be less than 0.
Answer:
2 units^2
Step-by-step explanation:
The area of a triangle is given by the formula
A = 1/2 bh where b is the length of the base and h is the height
b = 2 and h =2
A = 1/2 (2) * (2)
A = 1/2*4
A = 2 units^2
h(x) = -4 + 6
h(x) = 2
h(-2) = 2 because It's a constant function, when you substitute any x-values, you still get the same y-value.
Even if you substitute x = 1000, you still get y = 2.
Therefore, h(-2) = 2
-----------
If you mean h(x) = -4x+6
then h(-2) = 8+6 = 14
therefore, h(-2) = 14 for h(x) = -4x+6
