Y=kx
12=-4k
  k = -3

so when y = 15
y = kx
15 = -3x
  x = -5

----------------

$50 / 0.04 = $1250 (4% interest)

so
1250 * 0.06 = $75

answer
interest $75 at 6%

-----------------------------

y = kx
1/4 = 4k
k = 1/16

when x = 5
y = kx
y = 1/16(5)
y = 5/16 

-----------
y = kx
-5 = 4k
k = -5/4

direct equation
y = -5/4x

The shape on the left is translated to the shape on the right.
Angelina_Jolie [31]

Answer:

A

Step-by-step explanation:

Translation means moving so when saying Translate to the right your really moving it to the right. The questions says The shape on left is the original and the right is translated which means the left is the pre-image while right is the image. A is the only answer that doesn’t say the right is the pre image. Also, “ ‘ “ is used to distinguish the pre image coordinates vs the image coords so it easier.

Identify BR rounded to the nearest tenth. HELP PLEASE!!
ahrayia [7]

Answer:

<h2>BR ≈ 49.0</h2>

Step-by-step explanation:

Use cosine:

cosine=\dfrac{adjacent}{hypotenuse}

We have

adjacent=42\\hypotenuse=BR\\\alpha=31^o

\cos31^o\approx0.8572

Substitute:

\dfrac{42}{BR}=0.8572

\dfrac{42}{BR}=\dfrac{8,572}{10,000}          <em>cross multiply</em>

8,572BR=420,000                <em>divide both sides by 8,572</em>

BR=\dfrac{420,000}{8,572}

BR\approx49.0
