Answer:
D.
Step-by-step explanation:
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>

Answer:
for part B im not really sure
for part C the answer should be C
for part D the estimate population should be 6 million
for part E tge answer should be between 2025 to 2030
Answer:
2
Step-by-step explanation:
put the equation in slope intercept form y=mx+b
so y+5= 2x+2 after applying the distributive property
Get y by itself by subtracting 5 from both sides
so y= 2x +2-5
y=2x-3
slope is 2
