Step-by-step explanation:
Y= 4x +3, 4x + y =3 are they parallel or perpendicular
Answer: Neither
Step-by-step explanation:
When two lines are parallel, their slopes are the same.
When two lines are perpendicular, their slopes are opposite reciprocals. Opposite reciprocals equal -1 when multiplied together.
Equation #1: y = 4x + 3
The equation is in the form y = mx + b, so the slope is 4.
Equation #2: 4x + y = 3
We need to put this equation in slope-intercept form.
1) Subtract 4x from both sides
y = -4x + 3
The slope is -4.
-4 and 4 are neither equal nor opposite reciprocals, so they aren't parallel or perpendicular.
The slope of both lines is neither the same nor negative inverse of each other thus both lines will neither parallel nor perpendicular.
What is slope?A slope is a tangent or angle at a point or a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope is also calculated by differentiation for example slope of y = sinx will be y' = cosx.
As per the given lines,
y = 4x +3
The slope-intercept form is given as y = mx + c where m is the slope.
By comparing slope m = 4
4x + y =3 → y = -4x + 3
Slope m = -4
Since slopes are not the same thus they will be not parallel.
Perpendicular lines slope's multiplication gives -1.
Since, 4 x (-4) ≠ -1 thus both will be not perpendicular.
Hence "The slope of both lines is neither the same nor negative inverse of each other thus both lines will neither parallel nor perpendicular".

Answer: true
Step-by-step explanation:
Step-by-step explanation:
"A parallelogram has one pair of parallel sides."
False. A parallelogram has two pairs of parallel sides.
"If a quadrilateral is a rectangle then it is also a square."
False. A rectangle isn't necessarily a square. Rectangles are only squares when all four sides are equal.
"A parallelogram always has four congruent sides."
False. Parallelograms have two pairs of congruent sides. All four sides aren't necessarily congruent.
"If a quadrilateral is a square then it is also a rectangle."
True. All squares are rectangles.
"If a quadrilateral is a trapezoid then it is also a parallelogram."
False. Trapezoids have only 1 pair of parallel sides, and parallelograms have 2 pairs of parallel sides.

B is between A and C. AB = 5 and AC = 8. What is the length of BC
Answer:
BC = 3
Step-by-step explanation:
If you picture A, B, and C on a line, the first part of the line, AB, has a length of 5 and the total line, AC, has a length of 8 . Means that the second part of the line, BC, has a length of 3 because you would add the length of both the first and second part of the line in order to get the total length of the line.
AB + BC = AC
5 + BC = 8
BC = 3
