Step-by-step explanation:
-8/x - 11 = -2
First add 11 to both sides
-8/x - 11 + 11 = -2 + 11 simplifies to -8/x = 9
Now multiply both side by x
( -8/x) X ( x ) = ( 9 ) X ( x ) which simplifies to -8 = 9x
Divide each side by 9
-8/9 = (9x)/9 which simplifies to -8/9 = x or x = - 8/9
Area of a rectangle is found with the formula
A = Length x width
For your problem...
A = 4.325 x 3.6
A= 15.57 meters^2
Answer B
Answer: x = -9
Step-by-step explanation:
-10x - 10y = -10
when y = 10
-10x - 10(10) = -10
-10x - 100 = -10
Add 100 to each side
-10x = 90
Divide each side by -10
x = -9
-10(-9) - 10(10)
90 - 100 = -10
Answer:
![x \geq -\frac{7}{2}](https://tex.z-dn.net/?f=x%20%5Cgeq%20-%5Cfrac%7B7%7D%7B2%7D)
Step-by-step explanation:
we have
![y=4\sqrt{2x+7}](https://tex.z-dn.net/?f=y%3D4%5Csqrt%7B2x%2B7%7D)
we know that
The radicand must be greater than or equal to zero
so
![2x+7 \geq 0](https://tex.z-dn.net/?f=2x%2B7%20%5Cgeq%200)
Solve for x
Subtract 7 both sides
![2x+7-7 \geq 0-7](https://tex.z-dn.net/?f=2x%2B7-7%20%5Cgeq%200-7)
![2x \geq -7](https://tex.z-dn.net/?f=2x%20%5Cgeq%20-7)
Divide by 2 both sides
![x \geq -\frac{7}{2}](https://tex.z-dn.net/?f=x%20%5Cgeq%20-%5Cfrac%7B7%7D%7B2%7D)
