Line passes through (2, -1) and slope of 1/3

<h3><u>Step 1</u></h3>

y = mx + b,  Identify:  x = 2, y = -1, slope: \sf \frac{1}{3}

<u>insert following values</u>

\rightarrow \sf -1 = \dfrac{1}{3} (2) + b

<u>multiply</u>

\rightarrow \sf -1 = \dfrac{2}{3}  + b

<u>switch sides</u>

\rightarrow \sf b = -1 - \dfrac{2}{3}

<u>subtract</u>

\sf \rightarrow b = -\dfrac{5}{3}

<u>convert to mixed fraction</u>

\sf \rightarrow b = -1\dfrac{2}{3}

<h3><u>Step 2</u></h3>

y = mx + b,  m = \sf \frac{1}{3}, b = -1\frac{2}{3}

<u>insert following values</u>

\rightarrow \sf y =  \dfrac{1}{3} x -1\dfrac{2}{3}

blagie [28]

Answer:

Technician B

Step-by-step explanation:

It is very important that any car is taking for a test drive and a road test is carried out to check for any sort of problem with the transmission of the car or any leakages that may be found in the hydraulic circuits.

Technician B is very correct because when the hydraulic circuits is leaking, the front or forward clutch tends to slip thereby causing the shift for all forward gears to be delayed

Also,the sticking of the spool into the body of the valve can also cause the problem to occur as well.

Brian has 40000 to invest in a mix of corporate and municipal bonds. The corporate bond pays 10% simple annual interest and the
jonny [76]

Answer:

Sum of money invested in corporate bonds = 30,000

Step-by-step explanation:

Total sum = 40,000

The rate of interest for corporate bonds = 10 % = 0.1

The rate of interest for municipal bonds = 6 % = 0.06

Total interest = 3600

Let sum of money invested in corporate bonds = x

The sum of money invested in municipal bonds = 40000 - x

x × 0.1 × 1 + (40000 - x) × 0.06 × 1 = 3600

(0.1- 0.06)x + 2400 = 3600

0.04 x = 1200

x = 30,000

Since x =  sum of money invested in corporate bonds

So  sum of money invested in corporate bonds = 30000
