Start by getting one of the equations in terms of one variable, in this case lets put the first equation in terms of y
2x+y=3 ---> y=3-2x
now we plug that into the second equation
5x-2y=12 ---> 5x-2(3-2x)=12
we can then multiply and simplify
5x-2(3-2x)=12 ---> 5x-6+4x=12 ---> 9x-6=12 ---> 9x=18 ---> x=2
we can now plug x=2 into an equation to solve for y
2(2)+y=3 ---> 4+y=3 ---> y=-1

29-9=19
13+9=22
22-19=3
I don't know number 2, sorry.
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)
We know that both triangles are congruent because of the HL Theorem (in which both the hypotenuse and a leg are confirmed as congruent in a right triangle). Because of this, we know 4x = 6x - 58
Subtract 6x from both sides:
-2x = -58
Multiply both sides by -1:
2x = 58
Divide both sides by 2:
x = 29
The answer is Option C, x = 29
Answer:
C .) x2 – 2x – 4
