Do you know HOW?
Solve each system by graphing, Tell whether the system has one solution,
Infinitely many solutions, or no solution.
1. y - {x + 4
2. y=x+2
3. I + y = 2 the
y=-2r-1
y - 3x + 6
1+ y = -1
Solve each system using substitution.
4. x+y1
5. I - 4y = 11
2x + 3y = -4
2y -x--7
6. 2x + y = 1
- 2y = 23
Solve each system using elimination.
As a Matrix
2x + 3y = 10
8. x+y = -6
2x -y--14
r-y-6
9. 3x = -2y - 5
2y = -5 +5

Factor the expression. 4d + 12 __ (d +

The federal reserve controls certain interest rates in the united states. investors often try to speculate as to whether the federal reserve will raise or lower rates and by how much. suppose a company conducts extensive interviews with financial analysts, and as a result, predicts that "thefed" will increase rates by an average of 0.25 percentage points every six months for the forseeable future. which type of equation could be used to model the predicted interest rates over the next several years, assuming no other significant changes? a) a linear equation b) a quadratic equation c) a polynomial equation d) an exponential equation
