Answer:

A=5,B=9\\\\or\ A=-9,B=-5

Step-by-step explanation:

A(3-x)=-2x+B\\\\Given\ x=2\\\\Substitute\ the\ value\ of\ x\\\\A(3-2)=-2\times 2+B\\\\A=-4+B\\\\A=B-4\\\\So\ the\ value\ of\ A\ is\ 4\ less\ than\ the\ value\ of\ B.\\\\When\ B=9\Rightarrow A=9-4=5\\\\When\ B=-5\Rightarrow B=-5-4=-9\\\\Hence\ A=5,B=9\\\\or\ A=-9,B=-5

Please help!<br><br> Which line would be perpendicular?
givi [52]

Answer:

  • D. -2x + 2y = 1

Step-by-step explanation:

<u>When the line is given in standard form:</u>

  • ax + by = c, it has slope of -a/b

<u>Given line:</u>

  • 4x + 4y = 3

<u>It has a slope:</u>

  • m = -4/4 = -1

A line perpendicular to the given should have a slope m = 1 as negative reciprocal to the given

<u>Let's see which line has the slope of 1:</u>

  • 1. m = -(-1)/6 = 1/6 - NO
  • 2. m = -4/4 = -1 - NO
  • 3. m = -2/4 = -1/2 - NO
  • 4. m = -(-2)/2 = 1 - YES

Correct option is D

snow_lady [41]

Answer:

He would have $111,050.77 in the IRA.

Step-by-step explanation:

<u>What we know</u>:

The PMT is $1000

Rate of Interest (i in the formula) is 6.4% or 0.064 in decimal form

Number of periods (n) is 12

-

<u>Equation (Future Value Formula)</u>:

FV = PMT ( (1+i)^n -1) / i)

= 1000 ( (1+0.064)^12 -1) / 0.064)

FV = 17,269.22 (rounded)

-

A stands for amount

T stands for time period which is 30

<u>Finding IRA</u>:

A = FV (1+i)^t

= 17,269.22 (1+0.064)^30

= $111,050.77
