Answer:

Observe the attached image

Step-by-step explanation:

The inequality we have is:

$y$

This means that the region represented by this inequality includes all the values below the horizontal line $y = 2$ .

To graph this region, draw a dotted horizontal line that intersects the y axis at $y = 2$ . Then shade all the region that is below the horizontal line, as shown in the attached image.

► Find the percent change and tell whether it is a percent increase or a

Jlenok [28]

Answer:

1 Original amount: 20

End amount: 15

<h3>(20 - 15)/20 x 100 = (5/20) x 100 = 25% decrease</h3>

2 Original amount: 30

End amount: 45

<h3>(45 - 30)/30 x 100 = (15/30) x 100 = 50% increase </h3>

3 Original amount: 625

End amount: 550

<h3>550/625 =550 ÷ 625 =0.88</h3><h3>0.88 =0.88 × 100/100 =(0.88 × 100)/100 =88/100 =88% decrease</h3>

Please help me. give 10 points<br><br><br>

icang [17]

Answer:

x intercept: (3, 0), (7, 0)

y-intercept: (0, -21)

vertex : (5,4)

the graph points down

Step-by-step explanation:

f(x) = - (x - 3)(x - 7)

f(x) = - (x^2 - 7x - 3x + 21)

f(x) = - (x^2 - 10x + 21)

f(x) = -x^2 + 10x - 21

x-intercept when f(x) = 0 so

x - 3 = 0; x = 3

x - 7 = 0; x = 7

x intercept: (3, 0), (7, 0)

y-intercept when x = 0 so y = -21

y-intercept: (0, -21)

vertex:

x = -b/2a

x = -10/ 2(-1)

x = 5

plug in x = 5 into the equation to find y

y = -(5)^2 + 10(5) - 21

y = -25 + 50 - 21

y = 4

so vertex : (5,4)

Since a = - 1<0, the graph is going downward and has maximum

The drawing of the building, shown below, has a scale of 1 inch to 30 feet. What is the actual height, in feet, of the building?

andreyandreev [35.5K]

Answer:

Actual height of the building is 37.5 feet

Step-by-step explanation:

Formula to be used to get the actual length of the building,

Scale used = $\frac{\text{Dimension of image (on map)}}{\text{Dimension of actual}}$ = $\frac{1}{30}$

By this formula,

$\frac{1.25}{\text{Actual height}}=\frac{1}{30}$

Actual height of the building = 1.25 × 30

= 37.5 feet

Therefore, actual height of the building will be 37.5 feet.
