When solving (-2)5(-2)-8, you would first, following PEMDAS ofcourse, multiply -2 and 5, getting -10. Then you would multiply -2 and -10, which would be positive 20. Lastly, you would subtract 8 from 20, which equals 12.

I cannot find an answer within the options you gave me, but I am 100% sure that (-2)5(-2)-8 equals 12.

Hope this helped in some way! Please mark brainliest! Thank you v much! :)

The system of equations y = - 2x + 3 and y = xis graphed. What is the solution to the system of equations ?

nata0808 [166]

Answer:

(1,1)

Step-by-step explanation:

we have

$y=-2x+3$ ----> equation A

$y=x$ ----> equation B

we know that

The solution of the system of equations is the intersection point both graphs

The intersection point both graphs is the point (1,1)

see the given graph

therefore

The solution is the point (1,1)

Remember that

if a ordered pair is a solution of a system of equations then the ordered pair must satisfy both equations of the system

Verify

Substitute the value of x=1 and y=1 in each equation and analyze the result

Equation A

$1=-2(1)+3$

$1=1$ ---> is true

The ordered pair satisfy the equation A

Equation B

$1=1$ ---> is true

The ordered pair satisfy the equation B

therefore

The ordered pair (1,1) is a solution of the system because satisfy both equations

Fynjy0 [20]

Answer:

Functions are linearly dependent (are not linearly independent.)

Step-by-step explanation:

Remember that two functions f(x), g(x) and h(x) are said linearly independent on an interval I if the only solution to the equation

$\alpha f(x)+\beta g(x)+\omega h(x)=0, \ \text{for all } x\in I$

is the trivial one: α = 0, β = 0, ω = 0. If they are not linearly independent, they are called linearly dependent.

Now, let f(x), g(x) and h(x) be the functions:

$f(x)=e^{3x}+\cos(5x),$

$g(x)=e^{3x}-\cos(5x),$

$h(x)=\cos(5x).$

Then, letting α = 1, β= -1 and ω = -2, we see that:

$\alpha f(x)+\beta g(x)+ \omega h(x)=e^{3x}+\cos(5x)-e^{3x}+\cos(5x)+2\cos(5x)=0.$

Hence, the functions f(x), g(x) and h(x) are not linearly independent, or equivalently, are linearly dependent.

harina [27]

Answer:

After Two Hours.

Step-by-step explanation:

A simple way to do it is to:

1. Add 50+55, it is equal to 105. This is after one hour, so we know that it's more than this.

2. Add 50+55 to 105, This is after two hours, and we get 210, so we know that it has to be equal to 2 hours.
