(-2x)² + wx - 4 + (x)² + (5x + 6) = (-3x)² - 10

Simplify everything.

(-2x × -2x) + wx - 4 + x² + 5x + 6 = (-3x × -3x) - 10

Add / simplify like terms.

4x² + wx -4 + x² + 5x + 6 = 9x² - 10

Add like terms.

(4x² + x²) + 5x + wx + (-4 + 6) = 9x² - 10

Simplify.

4x² + 5x + wx + 2 = 9x² - 10

Get variables to one side.

So, subtract 2 from both sides.

4x² + 5x + wx = 9x² + (-10 + 2)

Then, subtract 9x² from both sides.

(4x² - 9x²) + 5x + wx = -8

Simplify.

-5x² + 5x + wx = -8

~Hope I helped!~

Use the given values of n and p to find the minimum usual value μ−2σ and the maximum usual value μ+2σ. Round to the nearest hund
lbvjy [14]

Answer:

μ−2σ = 1,089.26

μ+2σ = 1,097.62

Step-by-step explanation:

The standard deviation of a sample of size 'n' and proportion 'p' is:

\sigma=\sqrt{\frac{p*(1-p)}{n} }

If n=1139 and p =0.96, the standard deviation is:

\sigma=\sqrt{\frac{p*(1-p)}{n}}\\\sigma = 0.001836

The minimum and maximum usual values are:

\mu-2\sigma = (p-2\sigma)*n\\\mu+2\sigma = (p+2\sigma)*n

\mu-2\sigma = (0.96-2*0.001836)*1139\\\mu-2\sigma = 1,089.26\\\mu+2\sigma = (0.96+2*0.001836)*1139\\\mu+2\sigma = 1,097.62

The price of a pair of jeans is $25. If there is a 15% discount, what is the sale price of the jeans?
dusya [7]

Answer:

$29.41

Step-by-step explanation:

You know the discount price is 25 and the original is unknown so call it x. The sale is 15% off and that means that the jeans are 85% of what they used to be since 100-15 is 85. Then you plug it into a formula of 25/x = 85/100 then you cross multiply to get 2500=85x and when you solve for x and round you get $29.41

If the function graphed is f(x), find f(1).
Crazy boy [7]
Locate 1 on the x axis. This is the horizontal number line. 

Draw a vertical line through 1 on the x axis. Extend this vertical line as far up and down as you can.

Notice how the vertical line crosses the blue curve. Mark this point. Then draw a horizontal line from this point to the y axis. The horizontal line will touch -4 on the y axis. So that means the point (1,-4) is on the curve.

If the input it is x = 1, then the output is y = -4

So that's why the answer is choice A
