Answer:
B 9, -9
Step-by-step explanation:
x^2 - 81 = 0
Add 81 to each side
x^2 = 81
Take the square root of each side
sqrt(x^2) = sqrt(81)
x = ±9
All four choices are correct responses to the question.
99 and 59
X=big number
X-40 = small
X+ x-40 =158
2X -40=158
2X =198
X=99. Big number is 99
99-40 =59
99+59=158

Step-by-step explanation:
Answer:
d: 4 r:5
Step-by-step explanation:
for domain the x coordinates doesn't go over -2 on the left or 2 on the right so if u add the units of the space in between it's 4 since 2- (-2)=4
for the range, the y coordinates never goes over 3 or -2 so range is 5 is u add the units in between
I hope that makes sense!
