Answer:
Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.
for a poetry contest the minimum length of a poem is 16 lines. The maximum length is 32 lines. Write an absolute value equation that represents the minimum and maximum lengths
Answer:
lx-24l ≤ 8
Step-by-step explanation:
lx-24l ≤ 8
x ≤ 8 + 24
x ≤ 32
-----------------
-x + 24 ≤ 8
24 - 8 ≤ x
16 ≤ x
The absolute value equation that represents the minimum and maximum lengths is 8 = |x - 24|.
What is absolute value?Absolute value is defined as the magnitude or size of a number, no negatives are allowed. The distance a number is from 0 on the number line is known as the absolute value of the number.
For example, |5| is 5 because it is 5 units away from 0. Also, |-5| is also 5 because -5 is 5 units from 0.
We have been given that for a poetry contest the minimum length of a poem is 16 lines. The maximum length is 32 lines.
To determine the absolute value equation that represents the minimum and maximum lengths.
First, we need to find the difference between both solutions.
⇒ 32 - 16 = 16
Then, divide it by 2.
⇒ 16/2 = 8
⇒ 8 = |x - 32 + 8|
we could also write: 8 = |x - 32 + 8|
⇒ 8 = |x - 24|
Therefore, the absolute value equation that represents the minimum and maximum lengths is 8 = |x - 24|.

Find the area of a rectangular garden plot that measures 21 ft by 25.2 ft. Report with the correct number of significant digits.
The area of a shape is the amount of space it occupies.
The area of the garden is 529.2 square feet
The given parameters are:
Shape: Rectangle
Dimension: 21ft by 25.2ft
The area of a rectangle is:
[tex]\mathbf{Area = Length \times Width}[/tex]
So, we have:
[tex]\mathbf{Area = 21 \times 25.2}[/tex]

The graph for Airplane A shows the speed at which it travels as a function of time. The graph for Airplane B shows the distance it travels as a function of time.
Use the drop-down menus to complete the statements below about the two airplanes.
PART A: Describe the speed for each airplane from 0 to t1.
Airplane A travels at a speed that is (increasing, decreasing, 0, constant, but not 0).
Airplane B travels at a speed that is (increasing, decreasing, 0, constant, but not 0).
Part B: Describe the speed for each airplane from t1 to t2.
Airplane A travels at a speed that is (increasing, decreasing, 0, constant, but not 0).
Airplane B travels at a speed that is (increasing, decreasing, 0, constant, but not 0).
Answer:
from 0 to t1
Airplane A travels at a speed that is increasing.
Airplane B travels at a speed that is constant but not 0.
from t1 to t2
Airplane A travels at a speed that is constant, but not 0
Airplane B travels at a speed that is 0.
The airplane A is travelling at a faster and faster rate from 0 to t₁, and airplane B moves at a steady but not zero speed from 0 to t₁
What is a line graph?A line graph is a graph made up of segments of straight lines that connect the depicted data points.
We have a graph for Airplane A shows the speed at which it travels as a function of time. The graph for Airplane B shows the distance it travels as a function of time.
From the graph A and B
From 0 to [tex]\rm t_1[/tex]
Airplane A is travelling at a faster and faster rate.
Airplane B moves at a steady but not zero speed.
From [tex]\rm t_1[/tex] to [tex]\rm t_2[/tex]
Airplane A moves at a constant speed, but not at zero.
Airplane B is travelling at a speed of 0.
Thus, the airplane A is travelling at a faster and faster rate from 0 to t₁, and airplane B moves at a steady but not zero speed from 0 to t₁

I hope I helped you^_^
Answer:
(x-5) (x-3)
Step-by-step explanation:
At first find two numbers, that if you multiply, you get +15x², and the same number, if you do addition, get -8x
Those numbers are: -5x and -3x.
Now replace the -8x with the -5x and -3x. (x² - 5x - 3x + 15)
Now factorise as normal. You should get (x-5) and (x-3)

Multiply the roots of the first and third terms together. Compare to the middle terms with the result in step two. If the first and last terms are perfect squares, and the middle term's coefficient is twice the product of the square roots of the first and last terms, then the expression is a perfect square trinomial.

What is an equivalent ratio of 5:9
Step-by-step explanation:
There is infinitely many ratios which are equivalent to 5:9. As we know always we can write divide as fraction, so . We can multiply nominator and denominator by the any number (but the same) and get another numbers but ratio will be the same, so equivalent.
For example
10:18,
15:27
Hope this helps.
Answer:
10:18
Step-by-step explanation:
Anything really just times both sides by the same number.
For example to get to 10:18 I multiplied both sides of 5:9 by 2.
If you were to multiply 5:9 by 3 (which would 15: 27) it would still be an equivalent to 5:9.

What number is 12 more than 1/3 of itself?
Answer:
18
Step-by-step explanation:
Let the number be x.
1/3 of itself is 1/3 x or x/3.
x = x/3 + 12
3x/3 - x/3 = 12
2x/3 = 12
3/2 * 2x/3 = 3/2 * 12
x = 18
Answer: 18
The equation is formed as x - x/3 = 12. Then the solution of the equation will be 18.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The number is 12 more than 1/3 of itself.
Let the number be 'x'. Then the equation is written as,
x = x/3 + 12
Simplify the equation, then the value of 'x' will be calculated as,
x - x/3 = 12
3x - x = 36
2x = 36
x = 36/2
x = 18
The equation is formed as x - x/3 = 12. Then the solution of the equation will be 18.

Answer:
63
Step-by-step explanation:
A median bisects the side that it is drawn to, so
DM = ME4x - 10 = 3x + 5x - 10 = 5x = 15So, FN = 4(15) + 3 = 63.
Once again, since a median bisects the side it is drawn to, NE = 63.

What values of x and y satisfy the system of equations
{8x+9y=−3
{6x+7y=1
Answer:
• Let's first assign identifications to the equations given:
[tex]{ \rm{8x + 9y = {}^{ - }3 \: - - - \{equation \: (a) \} }} \\ { \rm{6x + 7y = 1 - - - \{equation \: (b) \}}} \\ [/tex]
• There are various methods to solve this system of equation, namely;
Graphical methodSubstitution methodElimination methodCalculus (Calculator synthetic method)1. Graphical method
→ You'll have to draw a graph, demacate it very well following the suitable scale.
→ Get values to plot from both equation (a) and equation (b).
→ Draw respective lines of each equation. The point of intersection of the lines is the answer of the values of x and y.
→ It'll be in coordinate format i.e; (x, y)
2. Substitution method
→ Lemme first consider equation (a)
[tex]{ \rm{8x + 9y = {}^{ - }3 }}[/tex]
• make x the subject of the equation (a):
[tex]{ \rm{8x = - 3 - 9y}} \\ \\ { \rm{x = \frac{ - 3}{8} - \frac{9}{8}y }} \: { \rm{- - - \{equation \: (c)}} \}[/tex]
→ Considering equation (b) next
[tex]{ \rm{6x + 7y = 1}}[/tex]
• substitute x in equation (b) with x in equation (c)
[tex]{ \rm{6( \frac{ - 3}{8} - \frac{9}{8}y ) + 7y = 1 }} \\ \\ { \rm{ - \frac{9}{4} - \frac{27}{4} y + 7y = 1}} \\ \\ { \rm{ \frac{1}{4} y = \frac{13}{4} }} \\ \\ { \underline{ \rm{ \: \: y = 13 \: \: }}}[/tex]
• then find x using equation (c)
[tex]{ \rm{x = \frac{ - 3}{8} - \frac{9}{8} y }} \\ \\ { \rm{x = \frac{ - 3}{8} - \frac{9}{8} (13)}} \\ \\ { \underline{ \rm{ \: \: x = - 15 \: \: }}}[/tex]
3. Elimination method:
→ Here, we have to align the equations so that if we use addition or subtraction operations we remain with one term giving us zero [ eliminated ]
→ Multiply equation (a) by 6 and multiply equation (b) by 8. In order to eliminate x
→ Then we subtract equation (a) with equation (b)
[tex]{ \underline{ \rm{ - \binom{6(8x + 9y = - 3)}{8(6x + 7y = 1)} }}} \\ { \rm{ 0x \: - 2y = - 26 }} \\ \\ { \rm{ - 2y = - 26}} \\ \\ { \underline{ \rm{ \: \: y = 13 \: \: }}}[/tex]
• find x using equation (c)
[tex]{ \rm{x = \frac{ - 3}{8} - \frac{9}{8} y}} \\ \\ { \underline{ \rm{ \: \: x = - 15 \: \: }}}[/tex]
4. Calculator synthetic method:
→ To use this method, you must have a scientific calculator.
→ If you have it, follow the steps below;
Go to mode (press it 3 times until you see "EQN" )Press 1 or any number below the "EQN". It'll display "Unknowns" with 2 and 3 below it. 2 → Two equations system. 3 → 3 equations system.According to our question, it is a two equations system, press 2It'll display a, b and c [ a is the coefficient of x, b is the coefficient of y, c is the constant]For a1 press 8 then press "equal sign", b1 press 9, then equal sign, c1 press -3 then equal sign.Follow the same procedure for a2, b2 and c2Automatically, It will display the answersAnswer: x = -15, y = 13
