You can just add the terms:
<span>(-x^2+9)+(-3x^2-11x+4) = -4x</span>² - 11x + 13
Answer:
x = -21
Step-by-step explanation:
62 + 2x - 20 = 0.
Combine like terms
42 +2x =0
Subtract 42 from each side
42-42 +2x = 0-42
2x = -42
Divide each side by 2
2x/2 = -42/2
x = -21
Answer:
2/3
Step-by-step explanation:
It would be 2/3 because on the top you add two and then on the bottom you add three each time.
Answer:
Time in seconds when the ball is 4 feet above the ground is:
t= 0.6 and 2.9.
1.) Which variable did you plot on the x-axis, and which variable did you plot on the y-axis?
x-axis represents people's arms span, y-axis represents their corresponding height
2.) Explain why you assigned the variables in that way.
because you can find the height of people(y) by plugging arm span in x. And i can find people's arm span(x) by plugging height as y
