Find the midpoint M of the line segment joining the points P = (-4, 6) and Q = (8, -4).​
mrs_skeptik [129]

Answer:

M=(2,1)

Step-by-step explanation:

The mid points is half the distance of the x and y values so

-4 and 8 are 12 apart so 12/2=6 so -4+6=2

so the x value of M is 2

same for the y value 6 and -4 are 10 apart 10/2=5 and 6-5=1 so

so the y value of M is 1 so

M=(2,1)

The graph of g(x) = -x^2 is shifted 3 units left and 1 unit up. If this new graph is f(x), then what is the value of f(-1.5)

\begin{array}{llll}
f(x)=&{{  A}}({{  B}}x+{{  C}})+{{  D}}

with that template in mind, let's see.

to the left by 3 units, C = +3
up by 1  unit, D = 1

\bf g(x)=-x^2\\\\\\ g(x)=-1(1x+\stackrel{C}{0})^2+\stackrel{D}{0}\implies g(x)=-1(1x+3)^2+1
\\\\\\
g(x)=-(x+3)^2+1\impliedby f(x)\qquad \qquad f(-1.5)=-[(-1.5)+3]^2+1

and surely you know how much that is.
