Plot the vertex and the axis of symmetry of this function on the provided graph.
tia_tia [17]

Answer:

(-2,-6)

-2

Step-by-step explanation:

To get the vertex take the number that's in the parathenses with the x and flip it's sign (in this case to a negative) which means we have

-2

 this is the x coordinate of the vertex.

Next take the number that's being subtracted (or added) on the outside and leave that as is (-6)

This is the y coordinate

which means we have (-2,-6)

the axis of symmetry is just the x coordinate of the graph

which is -2

Find the value of R so the line that passes through each pair of points has the given slope ( -12, R ), ( 5 , -3), m = 2
KengaRu [80]

Answer:

-37

Step-by-step explanation:

1) to find the equation of the given line (its slop-interception form is y=mx+i, where m - slop, i - interception):

a) y=2x+i, where m=2;

b) it is possible to calculate the value of 'i' after the substitution the point (5;-3) into the equation y=2x+i:

-3=2*5+i; ⇒ i= -13;

c) the equation of the given line is y=2x-13.

2) to calculate the value of 'R':

if to substitute the point (-12;R) into the equation y=2x-13, then

R=2*(-12)-13; ⇒ R= -37.
