The measure of an angle's supplement is 44 less than the measure of the angle.

Luden [163]

Answer:

< 1 = 112 degrees

< 2 = 68 degrees

Step-by-step explanation:

< 1 = x

< 2 = x - 44

x + x - 44 = 180

2x = 180 + 44

x = 224/2

x = 112

Given that f(x) = x + 3<br> a) Find f(2)

Nataly_w [17]

${ \qquad\qquad\huge\underline{{\sf Answer}}}$

Here we go ~

In the above question, it is given that :

$\qquad \sf \boxed{ \sf f(x) = \frac{x + 3}{2} }$

A.) Find f(2) :

$\qquad \sf \dashrightarrow \: f(2) = \dfrac{2 + 3}{2}$

$\qquad \sf \dashrightarrow \: f(2) = \dfrac{5}{2}$

$\qquad \sf \dashrightarrow \: f(2) = 0.5$

B.) Find ${ \sf {f}^{-1}(x) }$ :

$\qquad \sf \dashrightarrow \: let \: y = f (x)$

so, we can write it as :

$\qquad \sf \dashrightarrow \: y = \dfrac{x + 3}{2}$

$\qquad \sf \dashrightarrow \: 2y = x + 3$

$\qquad \sf \dashrightarrow \: x = 2y - 3$

Now, put x = ${ \sf {f}^{-1}(x) }$ , and y = x and we will get our required inverse function ~

$\qquad \sf \dashrightarrow \: f {}^{ - 1}(x) = 2x- 3$

C.) Find ${ \sf {f}^{-1}(12) }$ :

$\qquad \sf \dashrightarrow \: f {}^{ - 1}(12) = 2(12)- 3$

$\qquad \sf \dashrightarrow \: f {}^{ - 1}(12) = 36- 3$

$\qquad \sf \dashrightarrow \: f {}^{ - 1}(12) = 33$

A point G on a segment on a segment with endpoints F(4, 8) and H(10, 12) partitions the segment in a 3:4 ratio. Find G. You must

Andru [333]

Suppose, we are given

two points as

F as (x1, y1)

H as (x2, y2)

assume it divides in m/n

we can use formula

$G=(x,y)=(\frac{mx_2+nx_1}{m+n}, \frac{my_2+ny_1}{m+n})$

now, we are given points as

F=(x1, y1)=(4,8)

$x_1=4,y_1=8$

H=(x2, y2)=(10,12)

$x_2=10, y_2=12$

$\frac{m}{n} =\frac{3}{4}$

so,

$m=3,n=4$

now, we can find

$x=(\frac{3*10+4*4}{3+4}, y=\frac{3*12+4*8}{3+4})$

$x=\frac{46}{7} , y=\frac{68}{7}$

so, point is

$G=(\frac{46}{7} , \frac{68}{7})$ .................Answer
