Hello there!

In this problem we are trying to find the value of b in the given equation: 8 + 3b = -13. To do this, we have to isolate b.

The first step is to subtract 8 from both sides of the equation.

8 - 8 + 3b = -13 - 8

3b = - 21

Next, divide both sides of the equation by 3.

3b÷3 = -21÷3

b = -7

So, -7 is your final answer!

Which represents the solution(s) of the graphed system of equations, y = x2 + x – 2 and y = 2x – 2? (–2, 0) and (0, 1) (0, –2) a
Luda [366]

ANSWER

(0,-2), (1,0)

EXPLANATION

The first equation is

y =  {x}^{2}  + x - 2

The second equation is

y = 2x - 2

We equate both equations to get,

{x}^{2}  + x - 2 = 2x - 2

{x}^{2}  + x - 2x - 2 + 2 = 0

Simplify

{x}^{2}  - x = 0

Factor

x(x - 1) = 0

Either

x = 0

Or

x - 1 = 0

x = 1

Put x=0 or x=1 into the second equation to get,

y =   2(0) - 2 =  - 2

Or

y =   2(1) - 2 =  0

Therefore the solutions are;

(0,-2), (1,0)

A tablet computer costs 189.69. it is marked up 30%. What is the final price of the tablet computer after its marked up.
saveliy_v [14]
The initial cost is 189.69. It is marked up 30%.

By simple calculations, 

Final cost of the tablet computer = Initial price + 30% of marked price

= 189.69 + (30/100 x 189.69)

This gives us the net value of 245.7. Hence the price of the computer after it's been marked up will be 245.7
