What are the terms in the expression 7x+4y+1
2 answers:
Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
Since there are 3 terms in the expression:
First term is 7x.
A term x with coefficient 7.
Second term is 4y.
A term y with coefficient 4.
Third term is 1 i.e constant term.
So, the respective three terms would be 7x, 4y, and 1.
Hence, Option 'd' is correct.

Answer:
The equation of a parabola is
Step-by-step explanation:
(h,k) is the vertex and (f,k) is the focus.
Thus, f = 1, k = −4.
The distance from the focus to the vertex is equal to the distance from the vertex to the directrix: f - h = h - 2.
Solving the system, we get h = 3/2, k = -4, f = 1.
The standard form is:
The general form is:
The vertex form is:
The axis of symmetry is the line perpendicular to the directrix that passes through the vertex and the focus: y = -4.
The focal length is the distance between the focus and the vertex: 1/2.
The focal parameter is the distance between the focus and the directrix: 1.
The latus rectum is parallel to the directrix and passes through the focus: x = 1.
The length of the latus rectum is four times the distance between the vertex and the focus: 2.
The eccentricity of a parabola is always 1.
The x-intercepts can be found by setting y = 0 in the equation and solving for x.
x-intercept:
The y-intercepts can be found by setting x = 0 in the equation and solving for y.
y-intercepts:
