If by 104 and 103 you meant 10^4 and 10^3 the difference would be 10 because you subtract them as exponents and get 10^1 which is just 10. If you meant 104 and 103 as they are then the difference would be 6 as 104 x 6 is 6 more than 103 x 6.

Which equation has the same slope as y = -5x - 4?

Sholpan [36]

Answer: Any equation that has a -5 before the x will have the same slope. Some examples could be:

y= -5x

y = -5x + 100

y = -5x - 3

Answer:

1.63 cm (across the centerline from release)

Step-by-step explanation:

If we assume time starts counting when we release the weight from its fully-extended downward position, then the position at 1.15 seconds can be found from ...

h(t) = -7cos(2πt/4)

h(1.15) = -7cos(π·1.15/2) = -7(-0.233445) ≈ 1.63412 . . . cm

That is, 1.15 seconds after the weight is released from below the resting position, it will be 1.63 cm above the resting position.

If it is released from above the resting position, it will be 1.63 cm below the resting position at t=1.15 seconds.

Write the augmented matrix for each system of equations.

Fudgin [204]

We are given the equations: 

10x = 10

-5x - 8y = 9

Since we don't have a coefficient of y in the first equation, we will rewrite the first equation as:

10x + 0y = 10

Writing an Augmented matrix for the 2 equations:

10x + 0y = 10

-5x - 8y = 9

$\left[\begin{array}{ccc}10&0|&10\\-5&-8|&9\end{array}\right]$
