X^2 +6x+30 in vertex form
Elina [12.6K]

Answer:

Step-by-step explanation:

Factoring  x2-6x-30

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -30

Step-1 : Multiply the coefficient of the first term by the constant   1 • -30 = -30

Step-2 : Find two factors of  -30  whose sum equals the coefficient of the middle term, which is   -6 .

     -30    +    1    =    -29

     -15    +    2    =    -13

     -10    +    3    =    -7

     -6    +    5    =    -1

     -5    +    6    =    1

     -3    +    10    =    7

     -2    +    15    =    13

     -1    +    30    =    29

Find the slope of a line that passes through points (-1,-5) and (6,9).
Nana76 [90]

Answer:

{ \rm{slope =  \frac{y _{2} - y _{1} }{x _{2} - x _{1}  } }} \\  \\ { \rm{slope =  \frac{9 - ( - 5)}{6 - ( - 1)} }} \\  \\ { \rm{slope =  \frac{14}{7} }} \\  \\ { \boxed{ \rm{ \:  \: slope = 2 \:  \: }}}

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC b
iragen [17]

The student made the mistake in Step 2.

It should be m∠o + m∠p = 180 (Supplementary angles)

If this is corrected, then, since m∠m + m∠n + m∠o = 180 from Step 1,

we have,

m∠m + m∠n + m∠o = m∠o + m∠p which is Step 3.

Cancelling m∠o both sides, we get,

m∠m + m∠n = m∠p which is Step 4.
