Answer:

0.5a+2.54=0.8a+4.94

0.5a-0.8a=4.94-2.54

-0.3a=2.40

a=-2.40/0.3=-8

Answer:

0.5a+2.54=0.8a+4.94

0.5a-0.8a=4.94-2.54

-0.3a=2.40

Answer:

  • A'(4, -4)
  • B'(0, -3)
  • C'(2, -1)
  • D'(3, -2)

Step-by-step explanation:

The coordinate transformation for a 270° clockwise rotation is the same as for a 90° counterclockwise rotation:

  (x, y) ⇒ (-y, x)

The rotated points are ...

  A(-4, -4) ⇒ A'(4, -4)

  B(-3, 0) ⇒ B'(0, -3)

  C(-1, -2) ⇒ C'(2, -1)

  D(-2, -3) ⇒ D'(3, -2)

_____

<em>Additional comment</em>

To derive and/or remember these transformations, it might be useful to consider where a point came from when it ends up on the x- or y-axis.

A point must have come from the -y axis if rotating it 270° CW makes it end up on the +x-axis. A point must have come from the x-axis if rotating it 270° makes it end up on the +y axis. That is why we write ...

  (x, y) ⇒ (-y, x) . . . . . . the new x came from -y; the new y came from x

If the point (5, k) lies on the line represented by the equation 2x + y = 9, the value of k is
Paladinen [302]

Answer:

<h2>k = -1</h2>

Step-by-step explanation:

We have the point (5, k) and the equation 2x + y = 9.

Put the coordinates of the point ot the equation:

x = 5, y = k

2(5) + k = 9

10 + k = 9         <em>subtract 10 from both sides</em>

10 - 10 + k = 9 - 10

k = -1

How do I fill in the percentages?
ra1l [238]

<em>All Answers Under </em><em>Other Answers:</em>

Explanation:

First, you need to add all of the numbers to find the total budget. The total budget is <u>$1,116.</u> Then, to find the percentages, you need to divide each sections' money by the budget. For example, for 'contributions', you will do $175.76/$1,116 and get 0.157. But, this is a decimal. To make it into a percentage, you move the decimal point 2 spaces to the right. .157 = 15.7% So, for the 'contributions' section, the answer is 15.7%. Another example. For the 'housing' section,  the amount was $350.84. Divide that by $1,116.

\frac{350.84}{1,116}=0.314

Move the decimal point <em>2 spaces to the right</em> -- 31.4%

<u>I hope you understand how I got these answers</u>

Clothing: 2.7%

Medical Expenses: 3.1%

Taxes: 9.5%

a line is perpendicular to y=-2x+5 and intersects the point (-4,2). what is the equation of this perpendicular line?
german

Answer:

y = 1/2x + 4

Step-by-step explanation:

If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.

So solve for b: using y = mx + b

2 = 1/2(-4) + b

2 = -2 + b

4 = b

Put it all together

y = 1/2x + 4
