Tell whether the lines for this equation are parallel, perpendicular or neither

Mathematics
1 answer:
Arisa [49]3 years ago

Answer:

Perpendicular

Step-by-step explanation:

Parallel lines are lines which do not intersect and their equations have the same slope.

Perpendicular lines are lines which intersect at 90 degree angles and their equations have slopes which are the negative reciprocal of each other. If the slope is 2 then the negative reciprocal would be -1/2.

To determine which this pair of equations is compare their slopes from slope intercept form.

y= 7/3 x +3                                        12x + 28y = 40 becomes y = -3/7 x + 10/7

The slope is 7/3.                                The slope is -3/7.

These are negative reciprocals of each other. The lines are perpendicular,

What is the inverse of the function f(x) = one-quarterx – 12? h(x) = 48x – 4 h(x) = 48x + 4 h(x) = 4x – 48 h(x) = 4x + 48
NISA [10]

Answer:

The inverse function h(x) = 4x + 48

Step-by-step explanation:

Here, we want to find the inverse of a function

The function is;

f(x) = x/4 -12

now, let this value equals m

so;

m = x/4 -12

we now try and make x the subject formula and this gives us the inverse.

m = (x-48)/4

4m = x -48

x = 4m + 48

substitute m for x

which implies 4x + 48

This is the inverse of the function

What is the slope of a line perpendicular to the line whose equation is x-y=6x. Fully reduce your answer.
Over [174]

Answer  

1/5

Step-by-step explanation:

The slope of a perpendicular line is the negative reciprocal. Since y=-5x(m=-5), the slope is -(-1/5) which is 1/5

A total of 200 10-year-old children of similar intellectual abilities participated in a noise experiment in their classrooms. Th
Vladimir79 [104]

Answer:

The dependent variable for this experiment is the ability of students with similar intellectual abilities to recall the meaning of a symbol in a textbook one week after the start of the experiment which depends on the presence or absence of noise outside the classroom.

Step-by-step explanation:

In an experiment, the independent variable is the one whose value, form or outcome is not determined by any other variable in the experiment.

The dependent variable is the one whose value, form or outcome is determined by one or more other variable(s) in the experiment.

This experiment tests the abilities of students with similar intellectual abilities to recall the meaning of a symbol in a textbook one week after the start of the experiment.

This ability was made to depend on whether there was noise or no noise outside their classrooms.

Since, this variable to be measured is determined by another variable in the experiment, it is evident that this is the dependent variable for this experiment.

Hope this Helps!!!
