Take a look at <span>y = mx^2 – 5x – 2. This is a quadratic equation with a=m, b= -5 and c= -2. What is the discriminant, b^2 - 4ac? (-5)^2 - 4(m)(-2).
There will be 2 complex roots if this discrim. is < 0. Thus, solve
25 + 8m < 0:
Subtr. 25 from both sides: 8m < -25
Div. both sides by 8: m < -25/8
Conclusion: If m is less than -25/8, there will be no real roots (and thus, no x-intercepts). </span>

Hello there!
The Distributive Property allows us to multiply the number outside of the parenthesis by all inside numbers.
An example;
2(3 + 4)
2(3) + 2(4)
6 + 8
14.
Let's apply this to our current expression.
9(V + 5)
9(v) + 9(5)
9v + 45 is your expression.
I hope this helps!
Answer:
Step-by-step explanation:
Given
Solving (1): k(2)
Take t as 2 such that t = 2
This gives
Solving (2): k(t) = 7
Substitute 7 for k(t)
Add 1 to both sides
Divide both sides by 2
