Assuming the equations are:
<span>−4x+y=−6
8x−2y=14
The second equation can be rewritten (divide by -2) to
-4x+y=-7
This system has no solutions. If you would draw them as lines, they are two parallel lines that never intersect.</span>
(x+3)(x+3) = x^2 -3 + 3x
x^2 + 3x + 3x + 9 = x^2 + 3x - 3
x^2 + 6x + 9 = x^2 + 3x - 3
6x + 9 = 3x - 3
3x + 9 = -3
3x = -12
x = -4
Check:
(-4+3)^2 = (-4)^2 - 3(1+4)
(-1)^2 = 16 - 3(5)
1 = 16-15
1 = 1 :)
Answer:
The product would have 64 squares shaded out of 100.
Step-by-step explanation:
Multiply: 0.08 * 8. You get 0.64. This is basically 64/100. So it is 64 squares out of 100.
Answer:
The formula for the final velocity, bf in terms of initial velocity, v1, acceleration, a, and time is given as
Step-by-step explanation:
Given:
To Find:
bf = ?
Solution:
Acceleration:
Acceleration is defined as the ratio between the change in velocity of an object and the time it takes for the object to change the velocity.
In formula, this is written as:
Where,
'a' is the Acceleration.
'vf' is the final velocity
.
'vi' is the initial velocity.
't' is the time it takes for the object to accelerate from vf to vi
Here it is given as
So,
Where,
'a' is the Acceleration
'bf' is the final velocity
.
'v1' is the initial velocity.
't' is the time it takes for the object to accelerate from bf to v1.
On Solving the above equation 'bf' we get
....As required
