Answer:
Inequality symbol = ≥
Solution = d≥4
Step-by-step explanation:
If a family drives 350 miles per day, then;
1 day = 350 miles
To determine the number of days they will use to reach at least 1400mles
d days = 1400miles
Divide both expressions
1/d = 350/1400
Cross multiply
350 * d = 1400
350d = 1400
Since we are told that it ia at least 1400miles, this means the total miles can be greater than 1400. Hence the correct inequality sign to use will be a greater than or equal to sign(≥).
The expression above becomes 350d ≥ 1400
Divide both sides by 3350
350d ≥ 1400/350
d≥ 4
Hence the solution that represent the situation is d≥ 4

Answer:
x = 2
Step-by-step explanation:
It is given that,
U is the midpoint of TV.
TU = x² + 2x – 2
UV = -x+8
We need to find a positive value of x.
For midpoint,
TU = UV
Putting values,
x² + 2x – 2 = -x+8
or
x² + 2x – 2+ x - 8= 0
x² +3x-10 = 0
x² +5x - 2x -10 = 0
x(x+5) -2(x+5) = 0
(x-2) (x+5) = 0
x = +2 and x = -5
Hence, the positive value of x is 2.
