Answer:
x = –1
Step-by-step explanation:
From the question given above, the following data were obtained:
y = √(–2x + 7)
y = 3
x =?
The value of x can be obtained as follow:
y = √(–2x + 7)
3 = √(–2x + 7)
Take the square of both side
3² = –2x + 7
9 = –2x + 7
Collect like terms
9 – 7 = –2x
2 = –2x
Divide both side by –2
x = 2 / –2
x = –1
Answer:
220 miles
Step-by-step explanation:
.18m + 11d = 61.60
d = 2
.18m + 22 = 61.60
Subtract 22 from both sides
.18m = 39.60
Divide both sides by .18
m = 220
