Answer:
y = 5x^2-5x-30
Step-by-step explanation:
A parabola with x-intercepts at (-2,0) and (3,0) has the equation
y = a(x+2)(x-3)
where a is to be determined.
We know that it passes through the point (0,-30), so
-30 = a(0+2)(0-3) = -6a
Therefore solve for a to get
a = 5
y = 5(x+2)(x-3)
y = 5(x^2-x+6)
y = 5x^2-5x-30
Do you have a picture of the angle?
Answer: <em>уравнение имеет 2 решения:</em>
<em> x₁ = - 4; x₂ = - 2.</em>
Step-by-step explanation:
<em>Ix + 3I = 1</em>
<em>1) x + 3 = 1</em>
<em> x + 3 - 3 = 1 - 3</em>
<em> x = -2</em>
<em>2) - (x + 3) = 1</em>
<em> x + 3 = - 1</em>
<em> x + 3 - 3 = - 1 - 3</em>
<em> x = - 4</em>
