I can't answer the last 2 but i can help your with the distributive property the answer to the first one is 66+6x because you distribute the 60 to each thing inside the parentheses 6×11=66 and six times X is 6X. The answer to the second one is 8x+56 because you distribute eight to x which is 8X and 8 times 7 which is 56
Answer:
y=4^x −1
x intercept is the point when y = 0, so you sub in 0 for y:
0 = 4^x - 1
4^x = 1
Any number excluding 0 that is raised to the the exponent 0 always equals 1, 0^0 is undetermined.
x = 0
x intercept = (0,0)
If the x intercept is at the origin (0,0) than the y intercept is also (0,0)
s is the only line that passes through (0,0)
Use the law of sines...(sina/A=sinb/B=sinc/C for any triangle)
sin90/1000=sin20/RS
RS=1000sin20/sin90
RS≈342 meters
