Answer:

f(x) = 3(x − 8)(x + 2)

Step-by-step explanation:

The roots are at x = 8 and x = -2. This means factored form would include

y = (x-8)(x+2), with some number a as the leading coefficient.

Multiplying through, we have

y = x²+2x-8x-16

y = x²-6x-16

To have a y-intercept at -48, this means we multiply the function by 3; this gives us

y = 3(x-8)(x+2)

Answer:

The number of combinations will she have to analyze is 10.

Step-by-step explanation:

We know that Boeing currently produces five models of airplanes for commercial sale. The airline that Lauren works for is rapidly expanding and would like to purchase three airplanes of different models to service various routes. We calculate the number of combinations will she have to analyze.

$C^5_3=\frac{5!}{3!(5-3)!}=\frac{5\cdot 4\cdot 3!}{3!\cdot 2\cdot 1}=10$

The number of combinations will she have to analyze is 10.

Ajay bought a fan and a heater for rs 4000. He sold the fan at a profit of a 25% and the heater at a loss of 5%. If he gained 7%

Alborosie

Answer: Heater -Rs 2400; Fan- Rs 1600

Step-by-step explanation:

Given

Ajay bought a fan and a heater for Rs 4000

Suppose the price of fan is x and that of heater is 4000-x

Profit on the fan is $0.25x$

Loss on heater is $0.05\times (4000-x)$

Total profit is 7% i.e. $0.07\times 4000$

$\therefore 0.07\times 4000=0.25x-0.05(4000-x)\\\Rightarrow 280=0.25x-200+0.05x\\\Rightarrow 480=0.3x\\\Rightarrow x=1600$

Thus, the price of heater is $4000-1600=Rs.\ 2400$

Price of fan is $Rs.\ 1600$

Price of heater is $Rs.\ 2400$

17) $x-8=11$

18) $9-x=5$

19) $x+6=7$

20) $x+(-4)=-18$

Step-by-step explanation:

17) The difference between a number and 8 is 11

Let number = x

then the equation will be:

$x-8=11$

Solving:

$x-8=11$

$x=11+8\\x=19$

18) Nine less than a number is five.

Let number = x

then the equation will be:

$9-x=5$

Solving:

$9-x=5\\-x=5-9\\-x=-4\\x=4$

19) Seven is equal to a number plus 6

Let number = x

then the equation will be:

$x+6=7$

Solving:

$x+6=7\\x=7-6\\x=1$

20) The sum of a number and -4 is -18

Let number = x

then the equation will be:

$x+(-4)=-18$

solving:

$x+(-4)=-18\\x-4=-18\\x=-18+4\\x=-14$
