The answers are A and D, because the definition of congruent shapes is that they are the exact same size and the same angle measures. Option A shows two right triangles, that are matching in size because of the lines on the lines showing the same size. Option d is correct because The three sides of triangle TUV match up with triangle WXY. Option C is incorrect because Angle B does not match angle G. Option b is incorrect because the triangles are not the same size.
I hope this helps!

Alex777 [14]

Answer:

f^{-1} (x)=\frac{x+6}{7}

Step-by-step explanation:

To find the inverse of a function, we must substitute in y for f(x), swap the locations of y and x, and then solve for y

y=7x-6\\\\x=7y-6\\\\x+6=7y\\\\y=\frac{x+6}{7} \\\\f^{-1} (x)=\frac{x+6}{7}

An animal shelter spends $3.00 per day to care for each cat and $6.50 per day to care for each dog. Amelia noticed that the shel
Ede4ka [16]

Answer:

There were 15 cats at the shelter on Friday.

Step-by-step explanation:

Cost of caring each cat = $3.00

Cost for caring each dog = $6.50

Total money spent by shelter = $84.00

Total Cats and Dogs in the shelter = 21

Let the number of cats in the shelter = k

So, the number of dogs in shelter =  21 -k

Also according to the question:

Total expenditure on cats + total expenditure on dogs = $84.00

or, k ($3.00) + (21-k)($6.50)  = $84.00

or, 3k + 136.5 - 6.5 k = 84

or, -3.5 k = 84 - 136.5 = -52.5

⇒3.5 k = 52.5  or k = 52.5/3.5 = 15

⇒  k = 15

Hence, the number of cats in the shelter was 15 on Friday.
