If the point (-1,2) lies on the graph of y=f(x), then a point on the graph of y=-2f(x)+5
tekilochka [14]

Answer:

(-1, 1)

Step-by-step explanation:

Multiply f(x) or y value by -2, so (-1, 2) -> (-1, -4)

Add 5 to the f(x) or y value since it is a vertical translation, so (-1, -4) -> (-1, 1)

A. y= 1/2x-14<br> B. y=1/2x-5<br> C. y=2x-14<br> D. y=2x-5
DanielleElmas [232]

Answer:

B. y=1/2x-5

Step-by-step explanation:

From the graph, we read the slope of line JK.

slope = rise/run = -3/-6 = 1/2

The equation we need has the same slope.

y = mx + b

y = (1/2)x + b

It passes through point P(6, -2). Now we find b.

-2 = (1/2)(6) + b

-2 = 3 + b

b = -5

The equation is

y = (1/2)x - 5

In the diagram below, BC−→− bisects ∠FBE
nirvana33 [79]

Answer:

<em>m∠EBC = 34° </em>

Step-by-step explanation:

m∠DBC = m∠DBE + m∠ EBC

m∠DBC - m∠DBE = m∠EBC

(12x - 3)° - (5x + 12)° = (3x + 13)°

12x - 5x - 3 - 12 = 3x + 13

4x = 28

x = 7

<em>m∠EBC </em>= (3(7) + 13)° <em>= 34° </em>
