8. Souve sath equation by gracking, Round to the nearest tenth.Z 4B = -7%0-7-6, -16,-11,5
1 answer:
Step 1: Write out the equation
Step 2: Rewrite the equation
Step 3: Plot the graph of y = x² + 7x + 6
Step 4: Find the solution of the equation x² + 7x + 6 = 0
The solutions of x² + 7x + 6 = 0 are the x-coordinates of the points where the curve y = x² + 7x + 6 cuts the x-axis.
From the graph, we can see that the points are (-6, 0) and (-1, 0)
Hence, the solutions are -6, -1

Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 3)² + (y - 7)² = 2 ← is in standard form
with centre = (h, k) = (3, 7) and r² = 2 ⇒ r =
To solve this equation we could use:
There will be:
