Mathematics

Answer: No

Step-by-step explanation: First, we need to understand that parallel lines are coplanar lines that do not intersect. On the other hand, perpendicular lines are lines that intersect at a right angle.

However, lines can't be both parallel and perpendicular because they either intersect each other at a right angle or never intersect.

So no, two lines can't be both parallel and perpendicular.

Answer:  The answer would be letter A

slope (m)=-9/2

intercept on x-axis=56/9

intercept on y-axis=28

Explanation:

18x+4y=112

(18x)/112+(4y)/112=1

(x/1)/(56/9)+y/28=1

intercept on x-axis=56/9

intercept on y-axis=28

now, 4y=-18x+112

y=-9/2x+28

so, slope (m)=-9/2

Step-by-step explanation:

Move all terms that don't contain  y  to the right side and solve.

y =  28  −  (9 x) /(2)

L length of rectangel (cm)

A area of rectangel (cm²)

we are told that:

the area of the rectangel is

A=LW

Differentiating wrt t (using the product rule) we get;

Pls help me with this answer choice question! brainliest, rattings, thanks etc.

Answer:

graph B

Step-by-step explanation:

Given

3y - 5x < - 6

Since the inequality is < then the line must be broken

If ≤ then line would be solid

The only possible graphs are B and D

Choose a test point in the shaded region of each graph and check validity

graph B (2, 0) ← substitute into left side of inequality

0 - 5(2) = 0 - 10 = - 10 < - 6 ← this is valid

graph D (0, 0 ) ← substitute into left side of inequality

0 - 0 = 0 > - 6 ← this is not valid

Hence graph B is the correct graph
