Answer:
RS = XY (since the two a triangles are similar, you have to match the sides up and then set the values equal to eachother to find the value of x)
3x +2 = 5x -3 (subtract 5x from both sides)
-2x +2 = -3 (subtract 2 from both sides)
-2x = -5 (divide both sides by -2 to isolate x)
x = 2.5 (take the value of x and plug it into the expression given for RS)
3(2.5) +2 (multiply)
7.5 +2 (add)
9.5 (this is the length of RS)

Answer:






Step-by-step explanation:
We are given the following in the question:

We have to find the growth rate z(t) in each of the following cases:
(a) z = xy

(b) z=x/y

(c) z=y/x

(d) z=x^(1/2) y^(1/2)

(e) z=(x/y)^2

(f) z=x^(-1/3)y^(2/3)

To solve this, first solve the part of the equation in parentheses: (-4+3) = -1. Then multiply using the exponent 2 squared is 2×2 which is 4. Now the equation is -4(-1)+4. Next you multiply, -4(-1)=4. You are then left with 4+4 which equals 8.
-4(-4+3)+2 squared
-4(-1)+2 squared
-4(-1)+4
4+4
8
Answer:
x= -3/4
Step-by-step explanation:
Combine like terms
21x+17=x+2
-17. -17
21x= x-15
-x -x
20x= -15
Divide
x= -0.75 or -3/4
