Answer:

f(x)=-6

Step-by-step explanation:

f(0.5) means that x=0.5, so you substitute the x with .5 and multiply it times 2 which will get you 1. Then you subtract 7 to get -6.

Answer:

f(0.5)=-6

Step-by-step explanation:

f(x)=2x-7 f(0.5)

Just put in 0.5 for the x.

f(x)=2(0.5)-7

f(x)= 1 - 7

f(0.5) = -6

I hope you understand how to do these

Hope this helped :)

Find the coordinates of point X that lies along the directed line segment from Y(-8, 8) to T(-15, -13) and partitions the segmen

Nataly_w [17]

Answer:

C. (-13, -7)

Step-by-step explanation:

The location of a point O(x, y) that divides a line AB with location A $(x_1,y_1)$ and B $(x_2,y_2)$ in the ratio m:n is given by:

$x=\frac{m}{m+n} (x_2-x_1)+x_1\\\\y=\frac{m}{m+n} (y_2-y_1)+y_1$

Therefore the coordinates of point X That divides line segment from Y(-8, 8) to T(-15, -13) in the ratio 5:2 is:

$x=\frac{5}{5+2} (-15-(-8))+(-8)\\\\x=\frac{5}{7} (-15+8)-8=\frac{5}{7}(-7)-8=-5-8=-13 \\\\\\y=\frac{5}{5+2} (-13-8)+8\\\\y=\frac{5}{7} (-21)+8=5(-3)+8=-15+8=-7$

Therefore the coordinates of point X is at (-13, -7)
