Answer:

-2

Step-by-step explanation:

-8 = 3y - 2

+2         +2           :Add two to both sides to cancel out the negative two

<u>-6 = 3y</u>

3      3                 :Divide both sides by 3 to cancel out the three in the three y                  to get y by itself

(-2 = y)

(y = -2)                 :Your answer should be -2

Malcom and Ravi races each other. The average of their maximum speeds was 260 km/h. If doubled, Malcom's maximum speed would be
Kay [80]

Answer:

Malcom's maximum speed is 200 km/h

Ravi's maximum speed is 320 km/h

Step-by-step explanation:

First we have to make two equations one that represents the maximum average speed of the 2 together and another that represents the relationship between their maximum speeds

R = Ravi's maximum speed

M = Malcom's maximum speed

(R + M) /2 = 260 km/h

2M = R + 80 km/h

we are going to solve for M in the first equation

(R + M) /2 = 260 km/h

(R + M)  = 260 * 2

M = 520 - R

we replace M with (520 - R) in the second equation

2M = R + 80 km/h

2(520 - R) = R + 80

1040 - 2R = R + 80

1040 - 80 = R + 2R

960 = 3R

960/3 = R

320 = R

replace R with its value in the first equation

M = 520 - R

M = 520 - 320

M = 200

Malcom's maximum speed is 200 km/h

Ravi's maximum speed is 320 km/h

how many years (to two decimal places) will it take an investment of $17,000 to grow to $41,000 if it is invested at 2.95% compo
Fofino [41]

Answer:

30 years

Step-by-step explanation:

Given data

P=$17,000

A= $41,000

R=2.95%

the expressio for the time is

t= ln(A/P)/r

t= ln(41,000 /17000)/0.0295

t= ln(2.41176)/0.0295

t= 0.8803/0.0295

t= 29.8

about 30 years

What is the slope of the line through (-4.2) and (3,-3)?​
Dennis_Churaev [7]

Finding the slope using the two points:

The formula for slope is

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

In this case...

y_{2} =-3\\y_{1} =2\\x_{2} =3\\x_{1} =-4

^^^Plug these numbers into the formula for slope...

\frac{-3-2}{3 - (-4)}

\frac{-5}{7}

^^^This is your slope

Hope this helped!

A line passes through the point (6,1)and has a slope of 3/2. write an equation in slope intercept form
Lerok [7]

Answer:

Step-by-step explanation:

Slope intercept form :  y - y1 = m(x -x1)

m = 3/2

(x1, y1) = (6, 1)

y -  1 = \frac{3}{2}(x - 6)\\\\y -1 = \frac{3}{2}*x -\frac{3}{2}*6\\\\y-1=\frac{3}{2}x-3*3\\\\y-1=\frac{3}{2}x-9\\\\y=\frac{3}{2}x-9+1\\\\y=\frac{3}{2}x -8
