The factored form would be (2x + 1)(x^2 - 7)
Answer:
What time period?
Step-by-step explanation:
Answer:
m∠3 = 112° m∠5 = 38° m∠6 = 68° m∠8 = 74°
You do the others
Step-by-step explanation:
Facts you need to solve this problem.
1. Vertical angles are congruent
2. Alternate interior angles are congruent when lines are parallel
3. Sum of the measures of the angles of a triangle is 180
4. Adjacent angles are supplementary when two lines intersect
m∠3 = 112° (Reason 1 above)
m∠6 = 180 - 112 = 68° (Reason 4)
m∠6 + m∠5 + 74 = 180° (Reason 3)
68 + m∠5 + 74 = 180
142 + m∠5 = 180
m∠5 = 38°
m∠8 = 74° (Reason 2)
That gives you a start, so I will let you find all the others. OK? I know you don't want to do that, but you need to be able to do this type of problem. Now, go for it!!
Answer:
simplifying
Step-by-step explanation:
of point B is equal to of point A. Correct option A).
<u>Step-by-step explanation:</u>
Here we have , a straight line in the graph between x-axis & y-axis . There are two points given here, A and B which lie in same line . Equation of line :
, passing through origin . General equation of a line is :
, where m = slope of line , c = x intercept , comparing this equation to to equation of line given in graph we get that m = 3/4 & c =0.
Useful info from here is slope = 3/4 . We know that slope = tan(theta) i.e.
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
, which is constant i.e. ratio of y over x is a constant .Hence , of point B is equal to of point A. Correct option A).
