Can someone please explain how to solve 3x+3=x-1 will give brainiest :)

1 answer:

6 0

3x+3 = x-1
2x+3 = -1 (subtracted x from both sides)
2x = -4 (subtracted 3 from both sides)
x = -2 (divided 2 from both sides).

Ok so if you have an equation with a variable on both sides like this : 5x-6=2x

salantis [7]

Answer:

the answer is x=2

Step-by-step explanation

First of all put all x in one side of equation and number to the other side

Bare in mind that when we move from one side of equation to another positive integers become negative and negative integers become positive

5x-6=2x

5x-2x=6 here we moved 2x to other side of equation thus, it become -2x, and -6 was moved to other side of equation thus it become 6

3x=6 we subtracted from 5x-2x and found 3x since we can subtract the variables having the same element i this case that is x

x=6/3 we divided 6/3 in order to find the value of x. please note that 3x means 3*x

x=2

Given that f(x) = x2 − 4x − 3 and g(x) = the quantity of x plus three, over four, solve for f(g(x)) when x = 9.

eimsori [14]

Hello! To find the composition of functions we want to take all the x values in f(x) and replace them with g(x). Then to solve for a specific value, we plug in that value for x. Let's look at the steps below
$f(x)=x^{2} -4x-3$
$g(x)=\frac{x+3}{4}$

So we find
$f(g(x))=f(g(9))=(\frac{9+3}{4})^2 - 4(\frac{9+3}{4})-3$
$=3^2 - 4(3)-3$
$= 9-12-3=-6$
Now we want to find the solution when x is 9 so we plug in a 9 whenever we see an x

To avoid mildew and mold, Clay's new oat barn has an open shaft lengthwise through the barn with small holes drilled throughout

Nadusha1986 [10]

Answer:

Therefore, Clay can order 1,776 cubic feet of oats.

Step-by-step explanation:

To determine how many cubic feet of oats the barn can hold, break the barn up into three sections, the rectangular prism that makes up the bottom section of the barn, the triangular prism that makes up the top of the barn, and the rectangular prism that makes up the shaft.

The rectangular prism that makes up the bottom section of the barn is 12 feet wide, 16 feet long, and 8 feet high. Use the formula for the volume of a rectangular prism to find the volume.

Therefore, the volume of the bottom rectangular prism is 1,536 cubic feet.

The triangular prism that makes up the top section of the barn is 12 feet wide, 4 feet high, and 16 feet long. Use the formula for the volume of a triangular prism to find the volume.

Therefore, the volume of the top triangular prism is 384 cubic feet.The rectangular prism that makes up the shaft through the barn 3 feet wide, 3 feet high, and 16 feet long. Use the formula for the volume of a rectangular prism to find the volume.

Therefore, the volume of the shaft is 144 cubic feet.

The total volume available to store oats is the volume of the bottom section plus the volume of the top section minus the volume of the shaft.
