In an absolute value equation, a negative value turns positiveIn an absolute value equation, a positive value stays positive2X – 6Y =12 & -4X – 5Y = 27
Answer:
x=3y+6
Step-by-step explanation:
1.
Let's solve for x.
2x−6y=12
Step 1: Add 6y to both sides.
2x−6y+6y=12+6y
2x=6y+12
Step 2: Divide both sides by 2.
2x ÷2= (6y+12)÷2
x=3y+6
during the first half of the year there were 54 students in the schools bicycling club. in the second half of the year the club had 68 members. find the percent of increase in club membership to the nearest whole percent
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%

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 ≥).

< Less than

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.

Liz makes and sells necklaces. It costs her $40 for the supplie s to make 50 necklaces. How much must she sell each one for in order to make a profit of at least $250?
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.
What is a proportion?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.

Find the area of the shaded region.
Answer:
100π - (96 + (13/2)√231 ) m^2
Step-by-step explanation:
We will solve this by finding the area of the triangles (the quadrilateral is cut by the diameter) and subtract it from the area of the circle.
There is a circle theorem which states that if a triangle is in the semicircle and the hypothenuse extends to the length of the diameter, the angle at B here is 90 degrees.
Since angle B is 90 degrees we can use the Pythagorean theorem (a^2 + b^2 = c^2) to find Line AC.
so 144 + 256 = 400
√400 = 20
So diameter is 20
Finding the area of the top triangle:
1/2(12x16) = 96cm^2
For the bottom triangle, we need the side DC to find the area. To find it we will apply the theorem once again.
400 = 169 + DC^2
DC^2 = 231
DC = √231
so the area of the bottom triangle is 1/2(13√231) = (13/2)√231
Now we add the area of the triangles for the quadrilateral and subtract from the circle area.
The circle area is 100π (πr^2)
Hence, the area of the shaded region is:
100π - (96 + (13/2)√231 ) m^2

Matthew launches a ball is at 34 meters per sec from a 28 meter tall platform. The function of the ball's height (h) at time (*) seconds after launch is
h(t) = -12t^2 + 34t + 28.
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

The sum of two numbers is 48. The smaller number is 20 less than the larger number. What are the numbers?
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

When the temperature stays the same, the volume of a gas is inversely proportional to the pressure of the gas. If a balloon is filled with 183 cubic inches of a gas at a pressure of 14 pounds per square inch, find the new pressure of the gas if the volume is decreased to 61 cubic inches
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.

Aubree makes $25 a week helping her mom with her siblings. She wants to buy a computer that cost $500. How many weeks will it take her to have enough money to buy the computer?
Answer:
20 weeks
Step-by-step explanation:
This question, luckily, can be solved with a very simple algebraic expression.
Let w = the amount of weeks.
[tex]25w = 500[/tex]
So from here, we need to divide both sides by 25 to get w by itself: [tex]w = 20[/tex]
Therefore, it will take Aubree 20 weeks to have enough money to buy the computer.

y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (4, - 6) and (x₂, y₂ ) = (0, 2 )
m = = = = - 2
The line crosses the x- axis at (0, 2 ) ⇒ c = 2

What is the slope of a line perpendicular to the line -2x + 9y = 8?
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!
