Answer:
Step-by-step explanation:
Collect like terms and simplify
Divide both sides of the equation by 18 and simplify
F is a function. It takes inputs and then produces an output.
The notation <span>f(x)</span> is saying more specifically that the function is taking an input x and producing the output <span>f(x)</span>.
For example, if you look at <span>f(x)=<span>x2</span></span>, you can think that f is the "squaring function", with input x and outputs <span>x2</span>.
You can think that <span>"f"</span> is like the name of the function.
<span><span>f1</span>(x)=<span>x2</span></span>
<span><span>f2</span>(x)=<span>6x</span>+3</span>
Above, you know which function I'm talking about if I say <span>f2</span>. But often, people will just call it as the function <span><span><span>f2</span>(x)</span></span>
Length = x, width = y
x = 2y - 10....so sub in 2y - 10 for y back in the other equation
2x + 2y = 88
2(2y - 10) + 2y = 88
4y - 20 + 2y = 88
4y + 2y = 88 + 20
6y = 108
y = 108/6
y = 18
x = 2y - 10
x = 2(18) - 10
x = 36 - 10
x = 26
so the length (x) is 26 mm and the width (y) is 18 mm
The width of the stamp is 8 mm less then the length (26 - 18 = 8)
if I'm right it would be 2/5. you get your answer by adding 2/5 and 1/5 then subtract 5/5- 3/5 to get 2/5
19/3 - 31/7.....LCD = 21
133/21 - 93/21 =
40/21 =
1 19/21 lbs.....closest answer is B...it is about 2 lbs
