Answer:

See below

Step-by-step explanation:

a)

  • 11x^2 + x^2 = (4x + 8)(3x - 3)
  • 12x^2 = 12x^2 + 24x - 12x - 24
  • 12x - 24 = 0
  • 12x = 24
  • x = 2

b)

  • x/3 - x/9 = 6
  • 3x/9 - x/9 = 6
  • 2x/9 = 6
  • 2x = 54
  • x = 27

c)

  • 6^(x + 9) = 36^x
  • 6^(x + 9) = 6^(2x)
  • x + 9 = 2x
  • 2x - x = 9
  • x = 9

d)

  • 4/9 + 1/a = 2/3
  • 1/a = 2/3 - 4/9
  • 1/a = 6/9 - 4/9
  • 1/a = 2/9
  • a = 9/2

e)

  • √x + 3 = 6
  • x + 3 = 6^2
  • x = 36 - 3
  • x = 33

f)

1.2m - 0.2 = 3.8 + m

  • 1.2m - m = 3.8 + 0.2
  • 0.2m = 4
  • m = 4/0.2
  • m = 20

g)

  • (x + 12)^2 = 9
  • x + 12 = ± 3
  • x = ± 3 - 12
  • x = - 9, x = - 15

The left side of a solid block is held at a constant temperature of 200°C. The temperature profile within the block is given by
Nikitich [7]

Answer:

with T = 50⁰C, we have:

50 = 200 - 5x - x²

<=> x² + 5x = 150

<=> x² + 5x - 150 = 0

=> x = 10

QUICKLY PLEASE!!<br> 18POINTS!<br> 6(3p – 2) = 24
Gekata [30.6K]

Answer:

p= 2

Step-by-step explanation:

So first you want to distribute the 6 to 3p-2 which basically means multiply

6(3p – 2) = 24

6 times 3p is 18 and 6 time -2 is -12

* remember a negative and a positive equal a negative*

18p-12=24

you want to get 18p by itself, so in order to do that you can add 12 to both sides because if you add 12 on the left side it cancels out -12 and whatever you do to one side you have to do it to the other so add 12 to 24 which is 36

18p = 36

since you want to get p by itself you divide p on both sides so it can cancel out 18 and 36/18 is 2

so p = 2

if you are wondering why i divide it and not subtract or add it is because 18 and p are stuck together so you have to divide but if it  was like 18 + p you can subtract because 18 and p arent together

If f(x) = 5x + 4, which of the following is the inverse of (fx)?​
lys-0071 [83]

Answer:

see explanation

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 5x + 4 ( subtract 4 from both sides )

y - 4 = 5x ( divide both sides by 5 )

\frac{y-4}{5} = x

Change y back into terms of x

f^{-1} (x) = \frac{x-4}{5}

Create a system of equations that can be used to determine the rental cost of each truck for the 1-day move. Be sure to specify
bogdanovich [222]

The equation are y = 0.59x + 29.95 for company A and y = 0.79x + 19.95 for company B.

<h3>Linear equation</h3>

Linear equation is in the form:

y = mx + b

where y,x are variables, m is the rate of change and b is the initial value of y.

Let y represent the total cost of rental for each truck in x hours.

From the table, for company A:

  • y = 0.59x + 29.95

For company B:

  • y = 0.79x + 19.95

The equation are y = 0.59x + 29.95 for company A and y = 0.79x + 19.95 for company B.

What is the perimeter of the triangle?<br>​
Naya [18.7K]

Answer:

30 units

Step-by-step explanation:

if you count the boxes that each side takes up you get the first side being equal to 5 units and the base being equal to 12 units. because this is a right triangle to find the length of the hypotenuse you have to use the Pythagorean equation. when you input the values into the equation you get 5^2 + 12^2 = 169 which square roots to 13. after doing this you have the length of the final side, now input them into the formula for the perimeter of a triangle which is a + b + c and you get a perimeter of 30 units,

Please mark as brainliest :)
