Answer: Estimate: 36 ? units ? miles per hour ? feet per second?
Exact: 35.32142857 but if you are supposed to use significant digits, 35.32 is probably good.
Step-by-step explanation: For the estimate, round off the fractions to whole numbers, so multiply 6 x 6 to get 36
For exact I converted the mixed numbers to improper fractions, 5 3/4 = 23/4 and 6 1/7 = 43/7. Then multiplied the numerators 23 x 43= 989. And denominators, 4x7=28.
Divide numerator by denominator 989/28= 35.321428571
The y-intercept, where it crosses the y-axis, is at 2.
The slope, which is rise over run, is -2.
Therefore, it is the first option. I hope this helps.

Answer:
102 feet tall
Step-by-step explanation:
12 multiplied by 8 1/2 to get 102
2x^2 + ax = x(2x+ 7)
2x^2 + ax = 2x^2 + 7x
Subtract 2x^2 from both sides
ax = 7x
a = 7
