Answer: This equation has <u>one solution.</u>
Steps:
2+4(3-4x) = 5x +9
First, we need to distribute to the terms inside the parentheses.
4 * 3 = 12 and 4 * -4= -16x
Our equation now looks like this:
2 + 12 - 16x = 5x + 9
We can now combine like terms. We have 2 like terms that we can combine:
2 + 12 + = 14
Our equation now looks like this:
-16x + 14 = 5x + 9
We can now use inverse operations to get rid of 5x. The inverse operation for addition is subtraction; so we subtract 5x on both sides. Remember, our goal is to isolate the x.
-16x + 14 = 5x + 9
-5x -5x
The fives cancel out. Our equation now looks like this:
-21x + 14 = 9
We can now use inverse operations to get rid of the 14:
-21x + 14 = 9
- 14 -14
The fourteens cancel out. Our equation now looks like this:
-21x = -5
Last step! Now we use inverse operations to isolate the x. -21 is being multiplied by x; the inverse operation for multiplication is division.
-21x/-21 = and -5/-21 = 5/21
x is equal to 5/21.
Hope this helps!
Answer:
B) 25 units
Step-by-step explanation:
Do the Pythagorean theorum. 7^2+24^2=625
sqrt of 625=25
There is no linear model because the temperature is independent of the level of humidity. You have have the same temperature at different humidity levels, or you could have the same temperature at different humidity levels.
i really dont know but i really need to points please
Hello :
the formula is : an = a1+(n-1)d a1 : the first term d : is the common diff
an = 1+(n-1)(4)
an =1+ 4n-4
an = 4n +<span>[ -3 ]</span>
