You can use cubes to help you write an expression and model the problem by using the cubes in replace of numbers. It should be a lot easier. Then after you finish you just have to write it down. There are other ways, but this is just one.
y = -
x - 1
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange - 7x + 5y = 12 into this form
add 7x to both sides
5y = 7x + 12 ( divide all terms by 5 )
y =
x +
← in slope- intercept form
with slope m = ![\frac{7}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B5%7D)
given a line with slope m then the slope of a line perpendicular to it is
perpendicular slope = -
= - ![\frac{5}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B7%7D)
The partial equation of the perpendicular line is
y = -
x + c
to find c substitute (- 7, 4 ) into the partial equation
4 = 5 + c ⇒ c = 4 - 5 = - 1
y = -
x - 1 ← in slope- intercept form
Answer:
This is a response bias
Step-by-step explanation:
Response bias is a general term for a wide range of tendencies for participants to respond inaccurately or falsely to questions. These biases are prevalent in research involving participant self-report, such as structured interviews or surveys. Response biases can have a large impact on the validity of questionnaires or surveys.
This is exactly what happens here in the excercise, the result of the poll do not match the vote count, both results do not match, therefore, we can see that a lot of people lied in the poll or simply did not answer it very well.
Answer:
1.Given
2. Substitution
3. Definition of alternate interior angles
4. If alternate interior angles are equal then the lines are parallel
We know, Volume of a Cone = πr² h/3
v = 3.14 * (11)² * 4.5/3
v = 3.14 * 121 * 1.5
v = 569.91 in³
In short, Your Answer would be Option C
Hope this helps!
