Answer:

yes, this is a function because each x value is paired with with exactly one y value (the first one in the multiple choice)

Step-by-step explanation:

For something to be a function an input can have only one output. Multiple different inputs can have the same output, but not the other way around.

Solve the following equations <br> 5^2x-2(5^x)-15=0

castortr0y [4]

Answer:

x = 1

Step-by-step explanation:

${5}^{2x} - 2( {5}^{x} ) - 15 = 0$

$( {5}^{x} {)}^{2} - 2 \times {5}^{x} - 15 = 0$

${t}^{2} - 2t - 15 = 0$

${5}^{x} t = - 3 \: \: .5$

${5}^{x} = 5$

$x = 1$

3x + 5y = 7<br> -3x - 2y = -1

Oksanka [162]

Answer:

(-1,2) y=2 x=-1

Step-by-step explanation:

This is a system of equations and in this you see there is 3x and negative three x. To solve this you need tp get rid of one of the variables. so we can add the two equations together to get 3y=6. This means that y=2 if we divide by 3 on both sides. Then we just plug 3 in for y and we get 3x+10=7. We subtract 10 on both sides to get 2x=-3 which means x=-1.
