Answer:
Its 180!
Step-by-step explanation:
Answer:
no real solutions
complex solutions: x = 0.5±i√10.75, y = -2.5±i·3√10.75
Step-by-step explanation:
The graph shows the line and parabola do not intersect, so there are no real solutions to this system of equations.
__
However, the complex x-solutions can be determined from the graph to be ...
x = 0.5 ±i√10.75
The corresponding y-values can be found from the equation
y = 3x -4 = 3(0.5 ±i√10.75) -4
y = -2.5 ± i·3√10.75
Answer:
8.6 × 10^5
Step-by-step explanation:
New Jersey 8th graders = 920,000
Rhode island 8th graders = 60,000
Difference in Rhode island 8th graders and New Jersey 8th graders population
= 920,000 - 60,000
= 860,000
Answer in scientific notation
860,000
The decimal point will move 5 places in
= 8.6 × 10^5
X^2+9x+9x+81
x^2+18x+81

Answer:
A: Store A will cost about $1.28 less
Step-by-step explanation:
Okay, let's find the unit rate of cost. To find that for store A, we divide 7.26 by 3, which gets us 2.42. For store B, we need to look for the first intersection. We find that at (20, 50). Let's divide 50 by 20. That gets us 2.50. Let's multiply 2.42 and 2.50 by 16. That gets us 38.72 for store A and 40 for store B. Let's subtract 38.72 from 40. That gets us 1.28. That means store A costs $1.28 less than store B. That makes our answer A.
