Answer:
x = -0.5 , x = -5.5Step-by-step explanation:
Solving
-4x² = 24x + 114x² + 24x + 11 = 04x² + 24x + 36 - 36 + 11 = 0(2x + 6)² - 25 = 0(2x + 6)² = 25⇒ 2x + 6 = ±5Case 1 : x = +5
2x + 6 = 52x = -1x = -1/2x = -0.5Case 2 : x = -5

The system of equations shown below is graphed on a coordinate grid:
3y + x = 6
2y − x = 9
Which statement is true about the coordinates of the point that is the solution to the system of equations? (5 points)
Hint: Add the two equations and use inverse operations. When you have your y-value, plug it into any of the original equations to find your x-value.
a
It is (−6, 4) and lies on both lines.
b
It is (−3, 3) and lies on both lines.
Answers
Step-by-Step Explanation;
Lets solve using Elimination Method;
=> 3y + x = 6 (Eq. 1)
=> 2y - x = 9 (Eq. 2)
Adding Eq. 1 and 2, we get :-
5y = 15 (‘x’ gets Eliminated)
=> y = 15/5 = 3
Therefore, y = 3
Substitute value of ‘y’ in Eq. 1 :-
3y + x = 6
3(3) + x = 6
9 + x = 6
x = 6 - 9
=> x = -3
Therefore, x = -3
This can be written as an ordered pair as (-3, 3) where the ‘x’ coordinate is the value if x and the y coordinate is the value of ‘y’.

[tex]\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}[/tex]
When solving an equation, we need to make sure that all variables are on the left-hand side, and all numbers are on the right-hand side.
Since we have numbers on both sides, we need to move all numbers to the right:-
[tex]\bold{5=\dfrac{10}{t} +3}[/tex]
[tex]\bigstar[/tex] Subtract 5 on both sides:-
[tex]\bold{0=\dfrac{10}{t} +3-5}[/tex]
[tex]\bigstar[/tex] On simplification,
[tex]\bold{0=\dfrac{10}{t} -2}[/tex]
[tex]\bigstar[/tex] Now, subtract 10/t on both sides:-
[tex]\bold{-\dfrac{10}{t} =-2}[/tex]
[tex]\bigstar[/tex] On simplification,
[tex]\bold{\dfrac{10}{t} =2}[/tex]
[tex]\bigstar[/tex] Multiply by t on both sides:-
[tex]\bold{10=2t}[/tex]
[tex]\bold{2t=10}[/tex]
[tex]\bigstar[/tex] Divide by 2 on both sides:-
[tex]\bold{t=5}[/tex]

A rectangle has an area of 243 square centimeters. Its length is 3 times its width. What are the dimensions of the rectangle?
Answers
Length - 27 cm
Width - 9 cm
Step-by-step explanation:Here we go (hope this helps),
The area of the rectangle is 243. To get area, you do length x width. Your equation will look like this
3x (x) = 243
Simplify this using PEMDAS
3x^2 = 243
Next, you divide both sides by 3 to undo the times 3
x^2 = 81
Then, you take the square root of both sides to undo the squared symbol
x=9
Using this, you know the width is 9. Since the length is 3x the width, you know that 3 x 9 is 27 and you can clearly see that the dimensions are 9 and 27!

The transformation that took place is a horizontal stretch by a factor of 2
How to explain the transformation?We are given that Polygon ABCD transformed to create polygon A'B'C'D'. Clearly, the polygon is first a translation of the polygon ABCD 1 unit to the right and then it is horizontally stretched by a scale factor of 2.
Since the length of the polygon was earlier 2 units and then the length of the Polygon A'B'C'D' is 4 units. Hence, the transformation that took place in the Polygon ABCD is a horizontal stretch by a factor of 2

What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Volume of cylinder = π * radius² * height
Volume = π * 4² * 9 cm = 452.16 cm³
Volume of the cube = 3 cm * 3 cm * 3 cm = 27 cm³
Number of cubes needed = 452.16 cm³ / 27 cm³ = 16.75

new type of ball that is supposed to travel significantly
farther than the company's previous golf ball. To
determine this, 40 new-style golf balls and 40 original-
style golf balls are randomly selected from the
company's production line on a specific day. A golf pro
randomly selects a ball, not knowing which type is
chosen, and hits it. The difference in mean distances
traveled (new - original) for the samples was 4.9 feet
Assuming there is no difference in distance traveled
between the two types of golf balls, 200 simulated
differences in sample means are displayed in the

Felipe and Samantha use a payment plan to buy musical instruments.felipe writes the equation y=-30x+290 to represent the amount owed y,after x payments.The graph shows how much Samantha owns after each payment Who will pay more each month
Answers
An equation is formed of two equal expressions. Felipe is paying $6 more each month.
What is an equation?
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation that represents Felipe's payment per month is given as y=-30+290, therefore, the amount that Felipe pays every month is the gradient of the line slope of the equation y=-30+290 which is 30.
Similarly, the graph showing Samantha's payment, the slope will be,
m = (y₂-y₁)/(x₂-x₁) = (240-0)/(0-10) = -24
Thus, we can conclude that Felipe is paying $6(30-24)more each month, because the amount paid by Felipe is 30, while the amount paid by Samantha is 24.
Hence, Felipe is paying $6 more each month.

Step-by-step explanation:
The two highlighted rows show that for the same amount of blue, Purple #1 uses more red than Purple #2.
Making blue's quantity as 3 parts for purple #1 implies red part becomes 1.5 to maintain the ratio 1:2
Purple #1 has 1/3 parts red and 2/3 parts blue. Purple #2 has 1/4th part red and 3/4th part blue.
Hence, Purple #1 is a redder shade of purple than Purple #2.
