Answer:

Step-by-step explanation:

a)

Find the vertex by completing the square to answer both a and b

d)

x-ints is when y=0

so use quadratic equation for

b^2-20b+200=0

a=1

b= -20

c=200

But notice these imaginary numbers means 0 x intercepts.

State if the pair of triangles are similar. If so, state how you know they are similar and
RideAnS [48]
They can’t be similar. Similar triangles have congruent corresponding angles, and two angles are given on each. Neither of those correspond to another on the opposite triangle. Basically, there’s no way to have three congruent angles, so they aren’t similar.

How to solve (x+3)/(8)-7
Mekhanik [1.2K]

Answer:

 x - 53

 ——————

   8

Step-by-step explanation:

STEP

1

:

           x + 3

Simplify   —————

             8  

Equation at the end of step

1

:

 (x + 3)    

 ——————— -  7

    8      

STEP

2

:

Rewriting the whole as an Equivalent Fraction

2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  8  as the denominator :

        7     7 • 8

   7 =  —  =  —————

        1       8  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(x+3) - (7 • 8)     x - 53

———————————————  =  ——————

       8              8
