Find (f+g)(x) and (f-g)(x)
f(x)=2x+7 g(x)=5x-4

Answers

Answer 1

Answer:

for (f+g)(x): 7x + 3; x = -3/7

for (f-g)(x): -3x - 3; x = -1

Step-by-step explanation:

(f+g)(x) = (2x+7)+(5x-4)

Eliminate parentheses.

2x + 7 + 5x -4

Combine like terms.

7x + 3

If you are solving for x, move the 3 to the other side.

7x = -3.

Then divide each side by 7.

x = -3/7

(f-g)(x) = (2x+7) - (5x -4)

Distribute the negative.

(2x+7) + (-5x+4)

Eliminate parentheses.

2x + 7 - 5x - 4

Combine like terms.

-3x -3

If you are solving for x, move the -3 to the other side.

-3x = 3

Then divide each side by -3.

x = -1.

Answers

Answer:

D. (-2, 6)

Step-by-step explanation:

First, isolate a variable in one of the equations (i.e y = or x =)

The first equation already has isolated x.

x = y - 8 or y - 8 = x

5x + y = -4

Substitute the isolated variable into the second equation.

5(y-8) + y = -4

There is now only one variable, y, in the equation. Now you can solve for y.

First, use the distributive property to get the equation

5y - 40 + y = -4

Then, add 40 to both sides.

5y + y = 36

Add like-terms.

6y = 36

Divide.

36 / 6 = 6

So, y = 6.

Now that we have one coordinate, y = 6, you can substitute for y in the first equation.

x = 6 - 8

Subtract.

x = -2

Your coordinates are now x = -2 and y = 6, or (-2, 6).

What is the density of the glass in 2.5 g/cm in kg/m

Answers

We are given:                                                                                                        

Density of glass in g/cm³ = 2.5

Finding the density in kg/m³:                                                                              

In converting 2.5 g/cm³ to kg/m³, we will first convert the g to kg

Converting the g to kg:

2.5 g/cm³ * 1

Since 1kg = 1000g, 1kg/1000g = 1

2.5 g/cm³ * 1kg / 1000g

the g in the numerator and the denominator will cancel out and we will get:

2.5 kg / 1000 cm³

Converting the cm³ to m³:

We know that 1 m³ = 10⁶ cm³

So, 10⁶ cm³ / 1 m³ = 1

Multiplying the density by 1

2.5 kg / 10³ cm³   *   1

2.5 kg / 10³ cm³   *   10⁶ cm³ / 1 m³

the cm³ in the numerator and the denominator will cancel out

2.5 * 10⁶ kg / 10³ m³

2.5 * 10³ * 10³ kg / 10³ m³

2.5 * 10³ kg / m³

2500 kg/m³

2 pt + 1c

Step-by-step explanation:

There are 2 cups in a pint. So, 2c = p, dividing 2 from both sides, we get

c = (1/2)p

Replace c with 1/2 p in the equation

5 pt - (2pt + (1/2)p)

= 5pt - 2pi - (1/2)p

= 3pt  - (1/2)p

= 2pt  + (1/2)p

Replace back (1/2)p for c

2pt  + (1/2)p =

2 pt + 1c
