Answer:

Yes.

Base: 4

Step-by-step explanation:

Since we have 4 to the power of x, we do indeed have an exponent. The -2 just signifies vertical movement down.

Find the equation of the line with slope 1 and y-intercept (0,−1).
DedPeter [7]

We will build the equation in the form of y = mx + b where 'm' is the slope and 'b' is the y-intercept.

We know the slope and we know the where the line intercepts the y-axis.

The answer:

y = 1x + -1

Because the coefficient of "1x" is just one we can simplify to the final answer:

y = x + -1

The given equation is in point-slope form.

The general form of an equation in point slope form is:

y- y_{1}=m(x- x_{1})

Here m is the slope and x_{1} and y_{1} are the coordinates of the point.

So in given equation the slope is 2/3, and the coordinates of point are (1,3)

6x + 5y = 4<br> - 6x + y = 20
Masja [62]

Answer:

x = -8/3

y = 4

Step-by-step explanation:

I assume you want to solve for x and y.

The best way to do this with the two formulas given is elimination. This means add the two equations together.

6x + 5y = 4

-6x + y = 20

The 6 x and -6x will cancel each other. By adding the like terms of the two together you will come out with

6y = 24

Now solve for y by dividing both sides by the 6.

y = 24/6 = 4

Now that we have y, you can plug it into one of the equations and solve for x.

Let's use -6x + y =20.

So plug in the 4 for y to get -6x + 4 = 20

Subtract the 4 from both sides then solve for y by dividing both sides by the -6.

-6x = 16

x = -16/6

You can reduce that down so that x = -8/3.
