Answer: the above stated equation is a quadratic equation
Step-by-step explanation:
Given the following equations
y = x^2 + 5x - 3....equation 1
y-x = 2
y = x + 2........equation 2
Let equation 1 equal equation 2
x^2 + 5x -3 = x + 2
Bringing the equation to one side and equating to zero
X^2 +5x - 3 -x -2 = 0
X2 + 5x -x -3 -2 = 0
X^2 + 4x -5
Solving the aquatic equation
(x + 5)(x -1) = 0
X + 5 = 0
X1 = -5
X- 1 = 0
X2 = 1
To prove:
Substitute the values for x1and x2 into the equation x^2 + 4x - 5 = 0
Yes It is a unit rate because there are 2 units in 1 rate... or so I think
Answer:
Nicole is now 15 years old
Christine is now 5 years old
Step-by-step explanation:
x = age Nicole
y = age Christine
x = 3y
x+5 = 2×(y+5) = 2y + 10
3y + 5 = 2y + 10
y + 5 = 10
y = 5
x = 3y = 3×5 = 15
