X= 30/r is the answer because if you divide both sides by r you are left with x=30/r because you cant divide 30 by r

If f(x) =1/x and g(x) = x - 2 what is f(g(x)) when X = 1

Fed [463]

Answer:

f(g(x)) = -1

Step-by-step explanation:

$f(x) = \frac{1}{x} \\ \\ g(x) = x - 2 \\ \\ \implies \: f(g(x)) = \frac{1}{x - 2} \\ \\ \implies \: f(g(1)) = \frac{1}{1 - 2} \\ \\ \implies \: f(g(1)) = \frac{1}{ - 1} \\ \\ \implies \: f(g(1)) = - 1$

YS is the perpendicular bisector of XYZ and YS is a shared side of XYS and ZYS. which of the following must be congrent in order

german

Answer:

The triangles SYX and SYZ are congrient so by CPCTC $XY\cong YZ$ , $XS\cong ZS$ and $\angle X\cong \angle Z$ .

Step-by-step explanation:

Given information: YS is the perpendicular bisector of XYZ.

In triangle YXS and triangle YSZ,

$\angle SYX=\angle SYZ$ (YS is the perpendicular bisector of XYZ)

$YS=YS$ (Common side, Reflexive property)

$\angle YSX=\angle YSZ=90^{\circ}$ (YS is the perpendicular bisector of XYZ)

By ASA postulate,

$\triangle SYX\cong \angle SYZ$

The corresponding parts of congruent triangles are congruent. so,

$XY\cong YZ$

$XS\cong ZS$

$\angle X\cong \angle Z$

Hugh bought some magazines that cost $3.95 each and some books thst cost $8.95 each he spent a total of $47.65 if Hugh bough 3 m

Arisa [49]

Find amount spent on magazines:

1 magazine = $3.95

3 magazines = $3.95 x 3 = $11.85

Find amount spent on books:

Amount spent on books = $47.65 - $11.85 = $35.80

Find number of books:

Number of books = $35.80 ÷ $8.95 = 4

Answer: Huge bought 4 books
