Solve the equation. –x + 8 + 3x = x – 6

Answers

Answer 1
Answer: First group the coefficients together on their side of the equal sign.
-x + 3x = 2x.

Then, since it is a positive number, subtract it from that side and the other side.

On the other side, the x becomes -x.

Add the 6 from the other side to the 8 to make 14.

14 = -x

Divide both sides by -1, to get the answer.

x = -14
Answer 2
Answer: -x+8+3x=x-6
8+2x=x-6
+6 +6
14+2x=x
-2x -2x
14/-1=-x/-1
-14=x

A cylindrical glass of soda has a mass of 700g. The glass itself has a mass of 80g. If the glass has a radius of 4cm and a height of 8cm, what is the density of the soda?

Answers

The density of the soda is 3.6 g/cm³

What is density?

Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume.

Given that, a cylindrical glass of soda has a mass of 700g. The glass itself has a mass of 80g, the glass has a radius of 4 cm and a height of 8 cm,

We are asked to find the density of the soda,

Density = mass / volume

Volume = 2π×radius×height

Therefore,

Density = 700/2π×4×8 [we will not add the mass of glass because we need to find the density of soda only]

Density = 700/194.68

= 3.59

= 3.6

Hence, the density of the soda is 3.6 g/cm³

Answers

all of them involve y intercepts

f(x) means y
g(x) means  y

y intercept is where the graph crosses the y axis or when x=0 so set x=0

f(x)
x=0 when y=-7.5
y int=-7.5


g(x)
x=0
set x=0
y=3^0-7
y=1-7
y=-6


f(x) yint=-7.5
g(x) yint=-6


A. y int of f(x) is less than yint of g(x)
-7.5<-6
true

B. this is oposite of A so this is wrong

C. this says that g(x) has no yint, false

D. they yints are eqla
-7.5=-6
false




answer is A 

Answer:

f(x)

x=0 when y=-7.5

y int=-7.5

g(x)

x=0

set x=0

y=3^0-7

y=1-7

y=-6

f(x) yint=-7.5

g(x) yint=-6

A. y int of f(x) is less than yint of g(x)

-7.5<-6

true

B. this is oposite of A so this is wrong

C. this says that g(x) has no yint, false

D. the yints are equal
