Answer:
Step-by-step explanation:
Step 1: Identify the variables
Step 2: Determine the variable range
Step 3: Determine the scale of the graph
Step 4: Number and label each axis and title the graph
Step 5: Determine the data points and plot on the graph
Step 6: Draw the graph
Given:
The equation is:
To find:
The value of y.
Solution:
We have,
On simplification, we get
Since LHS=RHS and the equation is free from the variable y, therefore the given equation is true for all real values of y.
Hence, all real values of y are solutions.
The correct answer is solve for y in the second equation.
Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. ...
Step 2: Subtract the second equation from the first.
Step 3: Solve this new equation for y.
Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
A and 90-a is the measure of the two angles
a=90-a-6
2a=84
a=42
42° and 48°
(x-4)² + (x-2)² = x²
(x² - 8x + 16 ) + (x² - 4x + 4) = x
2x² -12x + 20 = x
2x²-12x + 20 - x = 0
2x² - 13x + 20 = 0
(2x-5) (x-4) = 0
2x-5 = 0
2x = 5
x = ⁵/₂
x-4 = 0
x = 4
so x₁ = ⁵/₂ , and x₂ = 4
