The equations y=55x+50 and y=65x represents Rick's and Betty's trip.
Step-by-step explanation:
Given,
Head start of Rick = 50 miles
Speed of Rick = 55 mph
Let,
x be the number of hours
y be the total miles
Distance covered by Rick in x hours = Speed * Time + Head start
y = 55x + 50
Speed of Betty = 65 mph
Total miles = Speed*Time
y=65x
The equations y=55x+50 and y=65x represents Rick's and Betty's trip.

Answer:
D
Step-by-step explanation:
As the counter clockwise rule is A(x,y) becomes A'(-y,x).
So (1, -6) becomes (6, 1)

Answer:
y = -4/3x +2
Step-by-step explanation:
The slope-intercept form of the equation of a line with slope m and y-intercept b is ...
y = mx + b
To get your equation with slope -4/3 and y-intercept 2, you put -4/3 where m is, and 2 where b is.
y = -4/3x + 2

Answer:
76
Step-by-step explanation:
Move 22 to the left side of the equation by adding it to both sides.3x2−10x+2=03x2-10x+2=0The discriminant of a quadratic is the expression inside the radical of the quadratic formula.b2−4(ac)b2-4acSubstitute in the values of aa, bb, and cc.(−10)2−4(3⋅2)-102-43⋅2Evaluate the result to find the discriminant. hope this helps :)
