Answer:

<h2><em>5</em></h2>

<em>solution</em><em>,</em>

<em>given \\ x =  - 3 \\ y = 4 \\  -  \frac{1}{2} (2x - y) \\  =  -  \frac{1}{2} (2 \times ( - 3) - (4)) \\  =   -  \frac{1}{2}  \times ( - 6 - 4) \\  =  -  \frac{1}{2}  \times ( - 10) \\  =  - 1 \times ( - 5) \\  = 5</em>

<em>hope </em><em>this </em><em>helps.</em><em>.</em><em>.</em>

<em>Good </em><em>luck</em><em> on</em><em> your</em><em> assignment</em><em>.</em><em>.</em>

Answer:

5

Step-by-step explanation:

when the question asks for evaluate, always substitute the expression with the values given.

So, her x = -3 and y=4

So we find 1/2 of 2x - y

This is also half of -6-4 = -half of -10 = 5

Hope this helps,

Good Luck

Cookies are on sale! Today each cookie costs $0.75 less than the normal price. Right now if you buy 7 of them it will only cost
Anestetic [448]
Let's say that the price of each normal cookie is n.
The equation would then be 7(n - .75)=2.80.
Use distributive property, getting 7n - 5.25=2.80.
Add 5.25 to each side of the equation, getting 7n=8.05. 
Divide 7 from both sides of the equation, getting n=1.15.

The point P(6, –1) is translated according to the rule (x, y) → (x – 5, y – 2).
monitta

The <em>resulting</em> point by considering that P(x, y) = (6, - 1) and P'(x, y) = P(x, y) + (- 5, - 2) is equal to the coordinates P'(x, y) = (1, - 3). (Right choice: C)

<h3>How to determined a resulting point by translation</h3>

In this question we need to determine the new location of a point by using a <em>translation</em> formula. Translations are rigid transformations in which a point is translated on a <em>Cartesian</em> plane. We have the following formula:

P'(x, y) = P(x, y) + (- 5, - 2)     (1)

Where:

  • P(x, y) - Original point
  • P'(x, y) - Resulting point

If we know that P(x, y) = (6, - 1), then the resulting point is:

P'(x, y) = (6, - 1) + (- 5, - 2)

P'(x, y) = (1, - 3)

The <em>resulting</em> point by considering that P(x, y) = (6, - 1) and P'(x, y) = P(x, y) + (- 5, - 2) is equal to the coordinates P'(x, y) = (1, - 3). (Right choice: C)
