Let’s solve your equation step-by-step.
9( y- 2) - 8y =_16

Step 1: Simplify both sides of the equation

9(y-2)−8 y=−16

(9)(y)+(9)(−2)+−8y=−16

(Distribute)

9y+-18+-8y=-16

(9y+−8y)+(−18)=−16
(Combine like terms)

y + − 18 = − 16

y − 18 = − 16

Step 2: add to both sides

y − 18 + 18 = − 16 + 18

y=2

Answer: y=2

Find the total surface area of this triangular prism.<br> 21 cm<br> 29 cm<br> 22 cm<br> 20 cm

mixer [17]

Answer:

313

Step-by-step explanation:

First of all you need to find out the surface of the front.

So you need to do 29cm + 29cm = 58cm.

You then have to do 22cm + 22cm = 44cm

So if you add those two numbers up you will get the front surface which is 102cm.

Next, you need to find the surface of the side.

So you need to do 20cm + 21cm = 41cm

After that, you need to find the back surface.

So you need to add 22cm +22cm = 44cm

Then you have to do 21cm + 21cm = 42cm

Add those two together to get 86cm

Then, you need to do the bottom of the shape.

So you need to add 22cm + 22cm (again) = 44cm

You then need to do 20cm + 20cm = 40cm

Add those together to get 84cm

Finally, you need to add 84cm + 86cm + 102cm + 41cm = 313cm

So your answer is:

Surface: 313

Please resolve this problem for me! I've been having trouble with this for a while.

Answer:

a) 41

b) -31

c) 25/3

Step-by-step explanation:

The instructions explain what a function is pretty clearly.

Basically, whatever is in the parentheses next to the $f$ , you plug in to the expression that is the function.

ex: $f(x) = x + 4$

$f(5) = 5 + 4 = 9$

Okay, onto the problems:

a) $f(x) = 3x - 1$

First, plug in 14, since that is given:

$f(14) = 3(14) - 1$

and solve.

$f(14) = 42 - 1$

$f(14) = 41$

So, 41 is the answer to a.

b) Do the same thing you did in problem a. Plug in the number inside the parentheses and solve.

$f(-10) = 3(-10) - 1$

$f(-10) = -30 - 1$

$f(-10) = -31$

-31 is the answer to b.

c) For this problem, you have to do a bit of algebra.

First, take the base function f(x):

$f(x) = 3x - 1$

Then, set f(x) = 24:

$24 = 3x - 1$

and solve by isolating x.

$25 = 3x$

$\dfrac{25}{3} = x$

$x = \dfrac{25}{3}$

25/3 is the answer to c.
