Answer:
f( 1 ) = 3
Step-by-step explanation:
Given the linear function, f(x) = -4x + 7, we could easily find f( 1 ) by substituting the value of the input, x = 1, into the function.
f(x) = -4x + 7
f( 1 ) = -4( 1 ) + 7
f( 1 ) = -4 + 7
f( 1 ) = 3
Therefore, the output value is f( 1 ) = 3.
Answer: y=-6x-25
Step-by-step explanation:
Find slope of original line by solving for y
3y+6x=6
y+6x=2
y = -6x+2 <--- we have found the slope is -6
Using y-y1 = m (x-x1) find the equation for the parallel line:
y-(-7)= -6(x-(-3)) <--- plug in the point coordinates and slope into the equation and solve for y
y+7=-6x-18
y=-6x-25
I'm not sure what the ray exactly is but some examples of ray names are ray RT or ray TR. You basically switch the letters.
Step-by-step explanation:
(y-14)=8/2
y-14=4
y=4+14
y=18
