Answer:

Plot the following points on the graph

$(-1, \frac{1}{2})$ , (0, 1), (1, 2), (2, 4), (3, 8)

Step-by-step explanation:

If the equation for the line is y = $2^{x}$ , whatever the power/exponent "x" equals, then y is equal to however many times 2 is multiplied by x.

For example, if our domain is {-1, 0, 1 , 2, 3}

then we would plug in each x value into the exponent to find the y-value in order to plot the points to solve the problem.

If x = -1, then y = 1/2. **If there is an a negative exponent it would get turned into a positive fraction with the denominator as the positive version of that number.

$y = 2^{-1} = \frac{1}{2^{1} } = \frac{1}{2}$

If x = 0, then y = 1

**When the exponent is 0, the number automatically equals 1.

If x = 1, then y = 2.

If x = 2, then y = 4

If x = 3, then y = 8

So you would plot the following coordinates on the graph:

$(-1, \frac{1}{2})$

(0, 1)

(1, 2)

(2, 4)

(3, 8)

Simplify. (5x2+2x−5)−(3x2+3x+1)

guapka [62]

Answer:

x² - x - 6

Step-by-step explanation:

Step 1: Write expression

(5x² + 2x - 5) - (3x² + 3x + 1)

Step 2: Distribute negative

5x² + 2x - 5 - 3x² - 3x - 1

Step 3: Combine like terms (x²)

2x² + 2x - 5 - 3x - 1

Step 4: Combine like terms (x)

x² - x - 5 - 1

Step 5: Combine like terms (constants)

x² - x - 6

Shelby mixes a 25% bleach solution with 5 cups of a 10% bleach solution, resulting in a 20% bleach solution. The table shows the

german

Answer:

Step-by-step explanation:

We will use a system of equations to solve this. We do not know how much of the 25% bleach solution is used; we will use x to represent this. We know that 5 cups of the 10% solution was used. We do not know how much of the resulting solution we have; we will use y to represent this. This gives us the equation

x+5 = y

Using the decimal forms of the percentages for each solution, we have 0.25x (25% solution for x cups), 0.1(5) (10% solution for 5 cups) and 0.2y (20% solution for y cups); this gives us the equation

0.25x+0.1(5) = 0.2y

This gives us the system

$\left \{ {{x+5=y} \atop {0.25x+0.1(5)=0.2y}} \right.$
