They will meet at 3:00 p.m.

Since Ryan traveled 245 miles in 3.5 hours, he traveled at a speed of 245/3.5=70 mph.  Janelle traveled 260 miles in 4 hours; she traveled at a speed of 260/4=65 mph.

Together, they had traveled 245+260=505 miles by noon.  This leaves 910-505=405 miles to travel.

If Ryan stays at a constant rate of 70 mph, his distance is given by 70t.  If Janelle stays at a constant rate of 65 mph, her distance is given by 65t.  Their distances together equal 405:
70t+65t = 405

Combining like terms, 

135t = 405

Divide both sides by 135:
135t/135 = 405/135
t = 3

3 hours after noon will be 3:00 p.m.

Which equation represents a line that is parallel to the line y = - 4x +5?
Vikentia [17]
Y= -4x+3

slope is still the same so it would be parallel to that line. Only the y-intercept is different so it would just pass through a different point

AVprozaik [17]
\dfrac{x}{-2}=4\ \ \ |multiply\ both\ sides\ by\ (-2)\\\\(-2)\cdot\dfrac{x}{-2}=(-2)\cdot4\\\\\boxed{x=-8}\\\\\dfrac{x}{3}+13=13\ \ \ |subtract\ 13\ from\ both\ sides\\\\\dfrac{x}{3}+13-13=13-13\\\\\dfrac{x}{3}=0\ \ \ |multpily\ both\ sides\ by\ 3\\\\\not3^1\cdot\dfrac{x}{\not3_1}=0\\\\\boxed{x=0}

\dfrac{z}{2}+2=4\ \ \ |subtract\ 2\ from\ both\ sides\\\\\dfrac{z}{2}+2-2=4-2\\\\\dfrac{z}{2}=2\ \ \ \ |multiply\ both\ sides\ by\ 2\\\\\not2^1\cdot\dfrac{z}{\not2_1}=2\cdot2\\\\\boxed{z=4}

Identify the vertex point of the parabola.<br> A) (1,-2)<br> B) (5,3)<br> C) (0,4)<br> D) (3,0)
Helga [31]

Answer:

D

Step-by-step explanation: The vertex is where the curve of the parabola occurs. Pay attention to where the curve of the parabola exists, and write down its coordinates. Over here, the curve is on 3 of the x-axis, and the y-value is 0 because the curve is literally on the x-axis. Any point that is on the x-axis will have no y-value. Hence our answer is (3,0).
