Find the point-slope equation of the line using the point (3, 5) and 3/2 slope
Use the slash key (/) to indicate a fraction.
Answer:
y-5 = 3/2(x-3)
Step-by-step explanation:
The point slope form of the equation of a line is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y-5 = 3/2(x-3)

Answer:
The value of x = 6.5 units
Step-by-step explanation:
Given triangle is a right angle triangle;
Length of base = 2.5 unit
Length of perpendicular = 6 unit
Find:
The value of x
Computation:
Using Pythagoras theorem;
Hypotenuse² = Base² + Perpendicular²
Hypotenuse² = 2.5² + 6²
Hypotenuse² = 6.25 + 36
Hypotenuse² = 42.25
Hypotenuse = √42.25
Hypotenuse = 6.5 unit
The value of x = 6.5 units

Answer:
Step-by-step explanation:
Plane shapes in two dimensions (drawn on a flat piece of paper for example) have measurable properties apart from just their physical measurements of side lengths, internal angles and area. They can undergo transformations, whereby they can change position or size, or ‘aspect ratio’ (how tall and thin or short and wide they are).
This page explores congruence, symmetry, reflection, translation and rotation. These concepts are about how a shape’s position changes, relative to a reference, such as a line or a point.
We are faced with these ideas regularly in everyday life, in everything from product design, architecture and engineering, to occurrences in the natural world. Even matching the pattern on a roll of wallpaper involves these geometric ideas.
Congruence
Mathematics is full of complex terminology, but sometimes a complicated term can mean something really simple. This is true for congruence.
Two shapes that are congruent have the same size and the same shape. It’s as simple as that!
In the diagram below, shapes A, B, C and D are all congruent. Shapes E, F, G and H are not congruent.

I REALLY NEED HELP , “ a company is designing a new cylindrical water bottle. the volume of the bottle will be 207 cm *to the 3rd power* the height of the water bottle is 8.4 cm. what is the radius of the water bottle?”
Answer:
Radius, r = 2.80 cm
Step-by-step explanation:
Given the following data;
Volume of cylinder = 207 cm³
Height = 8.4 cm
Pie, π = 3.14
To find the radius of the water bottle;
Mathematically, the volume of a cylinder is given by the formula;
V = πr²h
Where;
V is the volume of a cylinder.
r represents the radius of the cylinder.
h represents the height of the cylinder.
Substituting into the formula, we have;
207 = 3.14 * r² * 8.4
207 = 26.376r²
r² = 207/26.376
r² = 7.85
r = √7.85
Radius, r = 2.80 cm

Both sides of an equation can be multiplied by the same number without changing the solution of the equation.
Answer:
Just as you can add or subtract the same exact quantity on both sides of an equation, you can also multiply both sides of an equation by the same quantity to write an equivalent equation. Let's look at a numeric equation, to start.

A courier service charges a flat rate of $12.50 per trip plus $0.60 per mile. They charged Films & More $23.30 to deliver a package. ( a. Write the equation for this situation) (b. How many miles did the courier service have to travel? )
Answer:
y = 0.6x + 12.5
The courier service had to travel 18 miles
Step-by-step explanation:
Create an equation where y is the cost to deliver a package, and x is the number of miles traveled.
Since the service charges $0.60 per mile, the cost can be represented by $0.60x.
There is a flat rate of $12.50, so this will be added to 0.60x.
Then, set this equal to y. Using this, create an equation:
y = 0.6x + 12.5
Find how many miles the courier service had to travel by plugging in 23.30 as y, and solving for x:
y = 0.6x + 12.5
23.3 = 0.6x + 12.5
10.8 = 0.6x
18 = x
So, the courier service had to travel 18 miles.

A magazine provided results from a poll of adults who were asked to identify their favorite pie. Among the respondents, % chose chocolate pie, and the margin of error was given as percentage points. Describe what is meant by the statement that "the margin of error was given as percentage points."
Answer:
Margin of Error concept & example
Step-by-step explanation:
Margin of Error refers to range of values around sample statistic, within confidence interval. It denotes, expected percentage points of difference from real population value.
Example : With 95% Confidence Interval with (lets say 4) percent Margin of Error implies that - statistic is expected to be within 4% deviation around population mean 95% of the time.
It applies to pie case also. People liking chocolate pie are likely to be within ME% around sample percentage, with probability of CI% .

Norio, Gayle, and Tonya are playing a card game. They have a stack of red cards, a stack of yellow cards, and a stack of green cards.
On each turn, the player spins a spinner with three equal-sized sections, one red, one yellow, and one green. The spinner tells the player what color cards to draw.
Then, the player rolls a number cube with faces numbered 1–6. The number cube tells the player how many cards to draw. For example, if Tonya spins green and rolls a 4, she draws 4 green cards.
How many possible outcomes result in drawing at least one red card? Explain your answer by describing all such outcomes.

The arc length EF of the circle is 2π. Therefore, option C is the correct answer.
What is arc length of a circle?The arc length is defined as the interspace between the two points along a section of a curve. An arc of a circle is any part of the circumference.
The formula to find the arc length of a circle is θ/360° ×2πr.
Given that, ∠EDF=π/2= 90° and radius of a circle = 4 units.
Here, arc length = θ/360° ×2π×4
= 90°/360° ×2π×4
= 1/4 ×2π×4
= 2π
Therefore, option C is the correct answer.

Explanation:
f(x) is equal to both x^2-2x+3 and also -6x at the same time. Set those two expressions equal to one another and solve for x.
x^2-2x+3 = -6x
x^2-2x+3+6x = 0
x^2+4x+3 = 0
(x+3)(x+1) = 0 .... see note below
x+3 = 0 or x+1 = 0
x = -3 or x = -1
Note: 3 and 1 multiply to 3, and also add to 4.
---------------------
Once we get the x values, we plug them into either equation to find the y value.
So if x = -3, then
f(x) = x^2-2x+3
f(-3) = (-3)^2-2(-3)+3
f(-3) = 9 + 6 + 3
f(-3) = 18
or we could say
f(x) = -6x
f(-3) = -6(-3)
f(-3) = 18
Both versions produce the same output when x = -3.
The second version is easier to work with.
Since x = -3 leads to y = 18, we know that (-3, 18) is one of the solutions. That explains where your teacher got (-3, 18) from.
-----------
We'll use this idea for x = -1 now
f(x) = x^2-2x+3
f(-1) = (-1)^2-2(-1)+3
f(-1) = 1 + 2 + 3
f(-1) = 6
or we could say
f(x) = -6x
f(-1) = -6(-1)
f(-1) = 6
Like before, both versions of f(x) produce the same output when the input is x = -1.
The other solution is (-1, 6)
