How many solutions does 3(x+5)=-4x+8 have?

Mathematics
1 answer:
nadezda [96]4 years ago
6 0

Answer:

1 Solution  [the solution is x = -1]

Step-by-step explanation:

We can use the distributive property [ a(b+c) = ab + ac ] and a little algebra to solve the equation.

The steps are shown below:

3(x+5)=-4x+8\\3x+15=-4x+8\\3x+4x=8-15\\7x=-7\\x=\frac{-7}{7}\\x=-1

By solving this equation, we see that there is ONLY 1 SOLUTION to this equation.

<u>Note:</u> whenever we have a linear equation (highest power of x is 1, such as this one), there will be one solution. If the highest power of x was 2, e.g. Quadratic, there would have been 2 solutions to that.

Which expression is equivalent to 5!<br> 5^4*3^2<br> 5-4-3-2-1<br> 5.4.3-2.1<br> 5+4+3+2+1<br> 5.1
baherus [9]
The first one is like 5x5x5x5 which is 625 multiplied by 3x3 which is 9 and together the product will be 5,625.

The second one is 5-4 which is 1-3 which is -2 - 2 = -4 - 1 which is -5 so it’s not it because it’s the opposite of the number we need to find.

The third one is kind of messed up because there’s no such thing as 5.4.3 so sorry I can’t do that one.

The fourth one is 15 because you basically add the numbers up.

And the fifth is not 5. It’s 5.1 so that’s not it either.

So I’m sorry I can’t find the answer but at least I have you some background :/

I need help. Can you help me ?

The value of X would be 3.6 because if you divide the 4 by 2 to get the half triangle you now know the base and height for the triangle. Now you have to use tangent -1 to figure out the bottom right angle which is 56.3 degrees. Once you have the angle you can use Sin to figure out the missing side.
