Ones that never intersect
A = the number before x^2 = 3
b = the number before x = 5
To find the axis of symmetry: -b/2a
x = -5/6
Answer:
The acceleration of the train is 0.5m/s²
Step-by-step explanation:
Given
Velocity of the train = 10m/s
Time taken = 20 s
Required
Find the acceleration of the train.
The Acceleration if an object is the rate of change of the velocity of the object over time.
In other words, acceleration is calculated by dividing velocity by time.
Mathematically,
Acceleration = velocity ÷ Time
By substituting 10m/s for velocity and 20s for time, we have
Acceleration = 10m/s ÷ 20s
Acceleration = 10/20 m/s²
Acceleration = ½m/s²
Acceleration = 0.5m/s²
Hence, the acceleration of the train is 0.5m/s²
Given:
The point is (-12,-8).
Rule of transformation is 
.
To find:
The coordinates of image after transformation.
Solution:
According to the rule of transformation , first the point is dilated by factor 
with origin as center of dilation after that it was rotated 270 degrees anticlockwise.
If a point is dilated by factor with origin as center of dilation, then
If a point is rotated 270 degrees anticlockwise, then
Therefore, the coordinates of image after transformation are (-2,3).
Answer:
D. x>7
Step-by-step explanation:
Multiply - and -3
x+3>10
Subtract 3 on both sides
x>7
(Remember you can only switch the symbol if you divide or multiply by negative it does not apply on addition or subtraction)
Hope this helps!
