Answer:
Width is 5 and length is 7
Step-by-step explanation:
You can solve the equation using the distributive property and inverse operations.
2x +2(x+2)=24
2x + 2x + 4 = 24
4x + 4 = 24
4x = 20
X = 5
This means the width is 5 and the length is 7.
Answer:
f⁻¹(x) = (x - 1)/8
Or
f⁻¹(x) = 1/8 x - 1/8
Step-by-step explanation:
To find the inverse of a function, switch the "x" and "y" variables, then isolate "y".
Remember <u>"f(x)" is the same thing as "y"</u>. Change from function notation to "y".
f(x) = 8x + 1
y = 8x + 1
<u>Switch the "x" and "y" variables</u>
x = 8y + 1
<u>Isolate "y"</u>. Move the "y" variable to the left for standard formatting
8y + 1 = x
8y + 1 - 1 = x - 1 Subtract 1 from both sides
8y = x - 1
Divide both sides by 8 and simplify

<u>Question 18 </u>
Isolate the variable by dividing each side by factors that don't contain the variable.
Inequality Form: x ≤ −10
Interval Notation: (−∞ , −10]
<u>Question 19</u>
Isolate the variable by dividing each side by factors that don't contain the variable.
Inequality Form: x ≤ 4
Interval Notation: (−∞ , 4]
Answer:
4. 34%
Step-by-step explanation:
By mixing 20% and 30%, it will be between 20 and 30, like 22, 24 or 28. You would need a higher concentration than 30 to mix in to get 34%.
