x = - 7

multiply both sides by (x - 10) to eliminate the fraction

391 = - 23(x - 10 ) ← ( distribute parenthesis )

391 = - 23x + 230 ← ( subtract 230 from both sides )

161 = - 23x ← ( divide both sides by - 23 )

\frac{161}{- 23} = x

- 7 = x ⇒ x = - 7

Why does the graph of a function shift left when K is positive and to the right when K is negative?
Sedaia [141]

Answer:

You can visualize this easily.

y=f(x+h)

Now if the argument of the function is taken as (x−h) the value of y will be f((x−h)+h)=f(x)  

The function y acquires the value of f(x) at (x−h) amounting to a left shift.

Hope this makes things clear.

PLEASE HELP! BRAINLIEST! So desperate.
PSYCHO15rus [73]

Answer:

<B = 15

Step-by-step explanation:

A triangle adds up to 180 degrees.

Since these triangles are similar, the sides are located in the same spot. (A is in same spot as D, etc.)

A=75

F=90

75 + 90 + x = 180

165 + x = 180

x = 15
