Answer:

117 cm²

Step-by-step explanation:

area of rectangle = 13 * 7 = 91cm²

area of upper one right angle triangle= 1/2 * 6.5 * 4 =13 cm²

area of both triangles = 13 cm² * 2 = 26 cm²

Total area = 91cm² + 26 cm²

--> 117 cm²

Given f(x)=x^2 7 and g(x)=x-4/x. find (g o f)(-1). hint: (g o f)(-1)=g(f(-1))

lianna [129]

I hope this helps you

x= -1 f (-1)=(-1)^2+7=1+7=8

g (f (-1))= g (8)

x=8 g (8)= 8-4/8=4/8=1/2

The set of ordered pairs below represents a linear function.

Pretty sure ( -2,-7) because from -1 you go over one then each y is going down 3 so -4 - 3 is -7

AB has coordinates A(-5,9) and B(7,- 7). Points P, Q, and I are collinear

VMariaS [17]

Answer:

$\overline{QT}$

Step-by-step explanation:

We want to find the coordinates of a certain point C(x,y) such that C divides $A(x_1,y_1)$ and $B(x_2,y_2)$ in the ratio m:n=3:2

The x-coordinate is given by:

$x=\frac{mx_2+nx_1}{m+n}$

The y-coordinate is given by:

$y=\frac{my_2+ny_1}{m+n}$

AB has coordinates A(-5,9) and B(7,- 7)

We substitute the values to get:

$x=\frac{3*7+2*-5}{3+2}$

$x=\frac{21-10}{5}$

$x=\frac{11}{5}$

and

$y=\frac{3*-7+2*9}{3+2}$

$y=\frac{-21+18}{5}$

$y=-\frac{3}{5}$

Therefore C has coordinates $(\frac{11}{5},-\frac{3}{5})$

The line segment that contains C is $\overline{QT}$
