Step-by-step explanation:

3x2−7x−20=03x2-7x-20=0

Use the quadratic formula to find the solutions.

−b±√b2−4(ac)2a-b±b2-4(ac)2a

Substitute the values a=3a=3, b=−7b=-7, and c=−20c=-20 into the quadratic formula and solve for xx.

7±√(−7)2−4⋅(3⋅−20)2⋅37±(-7)2-4⋅(3⋅-20)2⋅3

Simplify.

x=7±176x=7±176

The final answer is the combination of both solutions.

x=4,−53

Answer:

g(x)=\sqrt[3]{x-3}+4

Step-by-step explanation:

The function g(x) is a shifted version of the function f(x); f(x) is shifted by 3 along x-axis and by 4 along y-axis.

Another way of thinking about this is that the function g(x) contains points (3, 4); therefore,

g(x)=\sqrt[3]{x-3}+4

which goes through the point (3, 4).

3/5x=52 is the answer 120 or 130
postnew [5]
The direct answer to your question is: "No".
because in that equation, 'x' is not 120 or130.

Let's find out what 'x' actually is:

<u>3/5 x  =  52</u>

Multiply each side by  5 :      3x  =  260

Divide each side by  3 :       <em>  x  =  86 and 2/3 </em>

Problem 6
Leno4ka [110]

Answer:

8 rabbits

22 chickens

Step-by-step explanation:

c = chickens

r = rabbits

heads - c + r = 30

legs - 2c + 4r = 76

We can now use these two equations to create one by isolating the variable (c) in the first equation.

c = 30 - r

2c + 4r = 76

2(30 - r) + 4r = 76

60 - 2r + 4r = 76

2r = 16

r = 8

Now we know that there are 8 rabbits, which means that there has to be 22 chickens in order to have 30 heads.
