First you distribute what’s outside the parentheses (the -4)
-4•4= -4y
-4•-2= 8
New equation: -4y+8=12
Now you solve like a normal equation
12-8 is 4
New equation: -4y=4
Now divide
Answer:-1
Answer:15 percent
Step-by-step explanation:
(.75) / 5 = 3/20 = 15/100 = 15%
f(x) is read is function f of x.
Where x is the input variable and function f(x) gives output value of function for x input value.
For the given function, we have f(3).
If we compare f(3) by f(x), the x represented by input value 3.
Therefore, x value is 3 there.
And we also have f(x) =-5.
Because function value is -5. So we can read it as, "for x input value of the the function gives output value -5."
For the asked value of x is just x=3.
Answer:
Step-by-step explanation:
9.1 h + 11.6 t = 9.98(60)
9.1 h + 11.6 t = 598.8 ........ <em>(1)</em>
h + t = 60 ........ <em>(2)</em>
h = 60 - t
9.1(60 - t) + 11.6 t = 598.8
546 - 9.1 t + 11.6 t = 598.8
2.5 t = 52.8
<em>t</em> = 52.8 ÷ 2.5 = <em>21.12</em><em> </em><em>≈</em><em> 21</em> (lb.)
<em>h</em> = 60 - 21.12 = <em>38.88 ≈</em><em> 39</em> (lb.)
