Answer:
Step-by-step explanation:
1)y=-6x-14 ---------(i)
-x-3y=-9 ---------- (ii)
Substitution method:
Substitute y value in equ (i)
-x -3*(-6x-14) = -9
-x - 3*-6x -3*(-14)= -9
-x + 18x + 42 = -9
17x = -9 -42
17x = -51
x = -51/17
x = -3
Substitute x value in equation (i)
y = -6*-3 -14
y =18-14
y = 4
Answer:
The linear speed in which Darlene is traveling is 24.74 miles per hour.
Step-by-step explanation:
The wheel experiments rolling, which is a combination of translation and rotation. The point where linear speed happens is located at geometrical center of the wheel and instantaneous center of rotation is located at the point of contact between wheel and ground. The linear speed (), measured in inches per second, is defined by following expression:
(1)
Where:
- Radius of the wheel, measured in inches.
- Angular speed, measured in radians per second.
If we know that and , then the linear speed, measured in miles per hour, in which Darlene is traveling is:
The linear speed in which Darlene is traveling is 24.74 miles per hour.
Answer: B, the are parallel but not equal. They are parallel line because they move in the same direction and they are not equal because they have different magnitude.
Answer:
B. W,V,Z
Step-by-step explanation:
Collinear points are two more points in the same plane that lie in a straight line.
From the diagram, Z is the intersection of the two diagonals of quadrilateral VXWY.
The points V, Z and W lie along the same diagonal, hence they are collinear.
The point y, Z, and X also lie along the same diagonal, these are also collinear.
The correct choice is B
I think it’s C i think is right
