Answer:
The answer to your question is the last option
Step-by-step explanation:
Quadratic equation
2 = - x + x² - 4
Order the equation from the highest power to the lowest power. Do not consider 2 because it is not consider in the options given.
x² - x - 4 = 0
Identify a, b and c
(1) x² -(1) x - 4 = 0
a = 1 b = -1 c = - 6
Substitution

Answer:
A) y=-1/2x+55
Step-by-step explanation:
We can clearly see a negative trend/association between the number of hot drinks sold on a given day and the low temperature of that day. Therefore, the slope of the best line of fit must be negative, eliminating D and E. Also, notice that when the low temperature is 0°F, the number of hot drinks sold is about 55, which is a good indicator of our y-intercept or constant, eliminating choice C. Because the best line of fit is not so steep, the slope will be closer to 0 if it's a negative trend. This eliminates choice B, making the correct answer A.
Answer:
777 rice balls
Step-by-step explanation:
700700700 divided by 100100100 equals 7. 7 times 111 equals 777.
Answer:
C I think
Step-by-step explanation:
Mainly because from what I have seen, the line sort of goes in between both the y and x axis so.
Answer:
6.1 m
Step-by-step explanation:
Always draw a diagram! And now pythagorean theorem. a^2 + b^2 = c^2
Substitution:
a^2 + 2.8^2 = 6.7^2
a^2 + 7.84 = 44.89
a^2 = 37.05
a = 6.086...
Rounding <u>up</u> to one decimal point, thats 6.1 m
