Ad libitum [116K]2 years ago
4 0

Answer:

It should be B

Step-by-step explanation:

2 2 -1 2 - -3 2 (2+-1)

1. Always do what's in parentheses

so we know that 1 is a negative and 2 is bigger than that number so you would just subtract normally.

2 2 -1 2 - -3 2 -1

Then get all exponents done.

4 -1 - 9-1

3-9-1

-6-1

Which should give u -5

Solve the system of equations by graphing where f(x)=5-2x and g(x)=(2/3)x-2. What is the value of x? 0 1 2 3 4
vfiekz [6]

Answer:

The graph is uploaded in the attachment.

The value of x is 2.625.

Step-by-step explanation:

  • let us plot f(x), g(x) on y-axis

so, f(x)=y and g(x)=y.

  • the first equation can be written as y=5-2x
  • the general equation of a straight is y=mx+c

( where m is the slope and c is the y-intercept )

  • now comparing given equation with the general equation mentioned above, the slope of first line is -2 and its y-intercept is 5
  • the slope of second equation i.e, y=(2/3)x-2 is 2/3 and its y-intercept is -2.
  • now plot the graph using above information.

(y-intercept is the the coordinate of a point where the line intersects y-axis)

(slope is the angle made by the line with the x-axis)

  • by seeing the graph, the value of x is 2.625.

Which expression is equivalent to 1/4 x + 3 - 1/3 x + (-2) ?
nasty-shy [4]

Answer:

The value of your expression is 7/12x +1.

Step-by-step explanation:

 1/4x + 3 - 1/3x + -2              First, positive and negative is negative

= 1/4x + 3 - 1/3x -2                 Combine like terms, 1/4x and 1/3x

= 7/12x + 3 - 2                          Combine like terms, +3 and -2

= 7/12x +1

Like terms are when a number have similar exponents bases, variables or just plain numbers.

3x, 4x, 5x

1.02x^2, 1.02x^3
