X = 23
y = 7
x + y = ?
23 + 7 = 30
ANSWER: x + y = 30
Answer:The Total distance covered by the car is 875m
In the given scenario, it is the area under the speed curve, the straight line. Area = 625 + 250 = 875m.
Step-by-step explanation:
Answer:
It has one solution which is a=1
H (x) = 5x^2+40x+64
y = (5x^2+40x+60) + 4
y = 5(x^2+8x+12) + 4
y = 5(x+2)(x+6) + 4
y-4 = 5(x+2)(x+6)
This means that the solutions, or where the parabola crosses the x-axis, are at x+2=0 and x+6=0, or x=-2, -6
So the midpoint of -2 and -6 is -4, the axis of symmetry is x=-4
