1. m+ 10< 16

sleet_krkn [62]

Answer:

$1.\ m$

Step-by-step explanation:

1. Subtract 10 from both sides. Then:

$m+ 10< 16\\ m+ 10-10< 16-10\\m$

2. Divide both sides by -2. Notice that the direction of the symbol of the inequality will change. Then:

$-2g\geq8\\\\\frac{-2g}{-2}\geq\frac{8}{-2}\\\\g\leq-4$

3. Add 22 to both sides. Then:

$y-22< 19\\ y-22+22$

4. Divide both sides by -7. Notice that the direction of the symbol of the inequality will change. Then:

$-7b>-28\\\\\frac{-7b}{-7}>\frac{-28}{-7}\\\\b$

5. Subtract 30 from both sides. Then:

$h+30$

6. Divide both sides by -5. Notice that the direction of the symbol of the inequality will change. Then:

$-5x$

7. Subtract 13 from both sides. Then:

$t+13>22\\ t+13-13>22-13\\t>9$

8. Add 12 to both sides. Then:

$w-12< 16\\ w-12+12$

The function y = x 2 – 4x + 8 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence

Alla [95]

Answer:

Exterme Value: $(2,4)$ .

The bird reaches its minimum height which is 4ft affter covering a horizontal distance of 2 ft.

Step-by-step explanation:

The given function is $y=x^2-4x+8$ .

We add and subtract the square of half the coefficient of x.

$y=x^2-4x+(-2)^2-(-2)^2+8$ .

The first three terms form a perfect quadratic trinomial.

$y=(x-2)^2+4$ .

This function is now written in the form $y=a(x-h)^2+k$ , where (h,k) is the extreme value(vertex).

The extreme value or the vertex is $(2,4)$ .

Interpretation:

The bird reaches its minimum height which is 4ft affter covering a horizontal distance of 2 ft.

The regular price of a smart phone is represented by x. When an upgraded phone is released, the new price is 25% more than the o

VARVARA [1.3K]

1.25x

because 25% can be represented as 0.25. so as the new price would be 125% of the old one its 1.25x

Legend has it that a bull sasquatch in rut will howl approximately 9 times per hour when it is 40°f outside and only 5 times per

ahrayia [7]

The answer is 13.

To solve this question, you need to determine the slope of the function. if howl is y and the temperature is x of the graph, the slope would be:

9-5/(40-70)= 4/-30= -2/15

Using one of the point and the slope, you can find the number of howl

-2/15= 9-y/40-(-20)

9-y= -2/15 * 60

9-y= -4

y= 9+4= 13
