Answer:

We start on the number -3 on the number line. Since the b > -3 is using the greater than sign, it is an open circle and since the inequality is pointing to the right, we can draw the arrow going to the right on the number line.

Step-by-step explanation:

[tex]\dfrac{ b }{ 3 } +1 > 0[/tex]

Multiply both sides of the equation by 3. Since 3 is positive, the inequality direction remains the same.

[tex]b+3 > 0[/tex]

Subtract 3 from both sides. Anything subtracted from zero turns into a negative number.

[tex]b+3-3 > 0-3[/tex]

Simplify

[tex]b > -3[/tex]

Now we need to graph it:

Inequalities can be shown on a number line. Open circles are used for numbers that are less than or greater than (< or >). Closed circles are used for numbers that are less than or equal to and greater than or equal to (≤ or ≥).

Symbol Meaning

> Greater than

> Greater than or equal to

< Less than

< Less than or equal to

We start on the number -3 on the number line. Since the b > -3 is using the greater than sign, it is an open circle and since the inequality is pointing to the right, we can draw the arrow going to the right on the number line.

Answer:

17 seconds

Step-by-step explanation:

h(t) represents height, we want to know when the ball will return to a height of 28 feet. So our equation is..

28 = -2t² + 34t + 28

Now solve for t...

0 = -2t² + 34t (subtract 28 from both sides)

0 = t² - 17t (divide both sides by -2)

0 = t(t - 17) (factor out a t)

So

t = 0

or

t - 17 = 0

t = 17

0 seconds is the initial height. At 17 seconds, the ball will return to that height

Answer:

-9/2

Step-by-step explanation:

To make a slope perpendicular, you must find the slope in a y = mx+b format where the slope is easy to find. Add 2x to the opposite side and then divide the entire right side of the equation by 9 to get y = 2/9x +8/9. A perpendicular slope is just a negative reciprocal of the slope, so make 2/9 negative and flip around the numerator and denominator to get a perpendicular slope of -9/2. Hope that helps!

Answer:

34 + 14 = 48

Step-by-step explanation:

have a great day

Step-by-step explanation:

Let x = larger number

Let y = smaller numer

(1) x + y = 48

(2) x = y + 14

Solving (1) for x:

x = 48-y

Substituting this into (2) and solving for y:

48-y = y+14

48-2y = 14

-2y = -34

y = 17

x = 48-y = 31

So, the smaller number is 17 and the larger number is 31

If you're looking for the cartesian form of this straight line then that would be,

[tex] - 3x - 2y + 8 = 0[/tex]

If you're looking for the equation in the form of y=mx+b, then:

[tex]y = - \frac{3}{2} x + \frac{8}{2} [/tex]

[tex]y = - \frac{3}{2} + 4[/tex]

Where -3/2 is the slope of the line

and 4 is the intersection with the y-axis (0,4)

if you want to graph this line, just take values of x and find their y, and plot these points.

finally join the points to get the graph of the line.

Answer:

W=2

Step-by-step explanation:

Let's solve your equation step-by-step.

3w+4w=14

Step 1: Simplify both sides of the equation.

3w+4w=14(3w+4w)=14

(Combine Like Terms)7w=14/7w=14

Step 2: Divide both sides by 7.

7w7=14/7

Your answer comes out at, w=2

Answer:

42 pounds per square inches.

Step-by-step explanation:

The temperature stays the same, the volume of a gas is inversely proportional to the pressure of the gas.

⇒ [tex]V\propto \dfrac{1}{P}[/tex]

or

[tex]V_1P_1=V_2P_2[/tex]

Volume, V₁ = 183 cubic inches

Pressure, P₁ = 14 pounds/square inch

We need to find the new pressure if the volume is decreased to 61 cubic inches. Let P₂ is new pressure. So,

[tex]P_2=\dfrac{V_1P_1}{V_2}\\\\P_2=\dfrac{183\times 14}{61}\\\\P_2=42\ \text{pounds per square inch}[/tex]

Hence, the final pressure is 42 pounds per square inches.

Answer:

To the nearest whole percent is 26%

Step-by-step explanation:

First half of the year = 54 students

Second half of the year = 68 members

find the percent of increase in club membership to the nearest whole percent ?

% increase in club membership = (new member - old member) / old member × 100

= (68 - 54) / 54 × 100

= 14 / 54 × 100

= 0.259 × 100

= 25.9 %

To the nearest whole percent is 26%

Using proportions, it is found that she must sell each necklace for at least $5.80 in order to make a profit of at least $250.

A proportion is a fraction of a total amount

In this problem, it costs her $40 to make 50 necklaces. She wants a profit of at least $250, hence the 50 necklaces should sell for at least $250 + $40 = $290.

Hence, the minimum price for each one is given by:

$290/50 = $5.80.

She must sell each necklace for at least $5.80 in order to make a profit of at least $250.
