If we let y be equal to zero, we get the roots of the equation. Because the equation is already in the factored form, we then say that the roots of the equation are x = 3 and x = 5. Another thing that is notable of this equation is that the graph would pass the x-axis at the points 3 and 5.
This is a quadratic equation because there are two roots and the highest exponent achievable by performing the expansion of the terms is 2. this equation can be of a parabola and the opening is upward because of the positive value of the numerical coefficients both of y and x in the opposite sides of the equation.
It would be multiplication and subtraction
4(x-3)
four times
( the difference of a number “x” and three)
difference means subtraction every time.
3x - 8 = -2 |add 8 to both sides
3x = 6 |divide both sides by 3
<u>x = 2</u>
<em>x - 6 = 2 - 6 = -4</em>
Answer:
h(h(10))---> h(-4)---->10 ......hOh(10)=10
Step-by-step explanation:
x= 6√5
1) Considering the right triangle metric relations and examining the picture, in which we're looking for the altitude of the triangle. Let's pick the one for the height of the right triangle and the projections of the hypotenuse: 20,9
h²= m.n <em>In this triangle we can rewrite it as</em>
x²=20*9
√x²=√180
x=6√5, and -6√5 <em>The negative value does not fit into that</em>
So, x= 6√5
