Answer:

Adults: 75, girls: 100, Boys: 75

Step-by-step explanation:

2/5 x 250 = 100( girls)

3/10 x 250 = 75 (boys)

250 - (100 + 75) = 250 - 175 = 75 (Adults)

F(x)=−2x 2 +8x−10 \text{Find }f(-4) Find f(−4)

Sav [38]

Answer:

-74

Step-by-step explanation:

f(x) = -2x^2 +8x -10

Let x = -4

f(-4) = -2 ( -4)^2 +8(-4) -10

= -2(16) -32-10

= -32 -32-10

= -74

Wu make and fill out the table using equation Y = 4x - 2

Anvisha [2.4K]

Answer:

$x = \frac{1}{4} y + \frac{1}{2}$

Step-by-step explanation:

$y = 4x - 2$

first flip

$4x - 2 = y$

now add 2 to each side

$4x + 2 = y + 2$

now

$4x = y + 2$

divide by 4

$4x \div 4 = 4 + 2 \div 4$

$x = \frac{1}{4} y + \frac{1}{2}$

Doug was trying his best, but he still made some mistakes.

yanalaym [24]

Answer:

Solution: $n>-6$

Step-by-step explanation:

Error

Doug made mistake in the first step by adding 2 to both sides.

Doug made mistake in representing the solution in number line.

Explanation:

In order to solve for n we need to isolate $n$ . Adding 2 both sides will not eliminate 2 on left side. Instead it will make it $\frac{n}{3}+4>0$

In the number line if solution is $n>-6$ the the point -6 is not included.

Solution:

$\frac{n}{3}+2>0$

On subtracting 2 both sides will eliminate 2 on left side.

$\frac{n}{3}+2-2>0-2\\\\\frac{n}{3}>-2$

Multiplying both sides by 3.

$3\times\frac{n}{3}>-2\times3\\\\n>-6$
