Answer:

y = 45 / 2x + 50

Step-by-step explanation:

The best equation for the line of the best fit would be y = 45 / 2x + 50.

The slope would be 45 / 2 and the y-intercept would be ( 0 , 50 ).

I used the points, ( 0 , 50 ) and ( 4 , 140 ) to get the equation, slope, and the y-intercept.

I used those points because they were the most accurate ones that I know for now.

Also, remember the formula is, "y = mx + b."

AnnyKZ [126]

Answer:

<em>(1). </em>5^{4}<em> × </em>13^{7}<em> ; (2). 3 - 5x</em>

Step-by-step explanation:

1). [( - 5 )³ · ( - 5 )] ( 13^{-2} · 13^{9} ) = (-5)^{3+1} × (13)^{-2+9} = (-5)^{4} × 13^{7} = 5^{4} × 13^{7}

2). - 25x² ÷ 5x + 15x ÷ 5x = <em>3 - 5x</em>

A. The angles at the intersection of the two lines can be proven to be congruent and complementary . so they meet at a right angle and the lines are perpendicular.

<u>Step-by-step explanation:</u>

In above question, In order to find whether AB ⊥ CD, Using compass construction & rounder , keep the tip at A and cut arcs at line CD . Follow the same process again with tip at B and cut arcs at line CD . Do this both sides of Line CD i.e. on left side of AB & on right side of AB. Now, join the intersection points of both side arcs which are intersecting each other. Now, to prove both are right angle to each other i.e.  AB ⊥ CD , can be done by proving congruent  and complementary , so they meet at a right angle and Hence , the lines are perpendicular i.e. AB is inclined to CD at angle of 90°.
