Question 3: what is the x-intercept of the line 3x+4y=12?
question 3 options:
(4, 0)
(3, 0)
(0, 4)
(0, 3)

First option.

Step-by-step explanation:

It is important to remember that the line intersects the x-axis when .

So, given the line , you need to substitute into the equation and solve for "x", in order to find the x-intercept of this line.

Therefore, this is:

Therefore, this line intersects the x-axis at this point:

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
