If f(x)= 2x2-4x and g(x)=5-2x evalute f(x)-g(x) for x=5

dezoksy [38]

<span>f(x)= 2x²-4x
</span><span>g(x)= 5-2x

</span> f(x)-g(x) = 2x²-4x - ( 5-2x) = 2x² - 4x-5+2x= 2x² -2x-5
f(x)-g(x) = 2x² -2x-5
f(5)-g(5) = 2*5² -2*5-5=50-10-5 =35
f(5)-g(5) = 35

The average attendance of Everton football club fell by 7% in 1982. If 2030 fewer people went to matches in 1982, how may went i

nataly862011 [7]

Answer: 29000 people went in 1981.

Step-by-step explanation:

Let x= Attendance in 1981.

Given: The average attendance of Everton football club fell by 7% in 1982.

Difference in attendance from 1981 to 1982 = 0.07x

If 2030 fewer people went to matches in 1982,

$0.07 x=2030\\\\\Rightarrow x=\dfrac{2030}{0.07}\\\\\Rightarrow x=29000$

Hence, 29000 people went in 1981.

sergij07 [2.7K]

Answer: 24 cans

George has 9 fence

It requires $2\frac{2}{3}$ cans to paint a fence

So, 9 fence required

$\Rightarrow 9\times 2\dfrac{2}{3}\\\\\Rightarrow 9\times \dfrac{8}{3}\\\\\Rightarrow 3\times 8=24\ \text{cans}$

9 fence requires 24 cans

Manuel made $80 for 5 hours of work.

Virty [35]

Answer:

13 hours

Step-by-step explanation:

Let's first start by finding how much he makes in 1 hours:

$\frac{\$80}{5} =\$16$

Now we can set up two ratios

$\frac{16}{1} = \frac{208}{x}$

Solve by cross multiplying (multiply the numerator of the first fraction with the denominator of the second fraction and the numerator of the second fraction with the denominator of the first fraction)

16x=208

Divide both sides by 16 to isolate x

x=13

He would have to work 13 hours to make $208
