Answer:
y - 3 = 5(x + 1) (fully reduced point-slope form)
Step-by-step explanation:
Moving from the first point to the second, we see x increasing by 2 and y by 10. Thus, the slope of the line through these two points is m = rise / run = 10/2, or m = 5. Applying the point-slope formula y - k = m(x - h), we get:
y - 3 = 5(x + 1) (fully reduced point-slope form)
or y = 3 + 5x + 5, or y = 5x + 8 (slope-intercept form)

From PEMDAS... I'd go for the parenthesis first
(3+3+3) = 9
The new expression now is
4+4+5x2x5+9x 6x6+2+2
Then Onto Multiplication
5x2x5= 50
9x6x6=324
It now becomes

Trigonometry review.
Enter the statement, with the values in the same order, but with parentheses so that the statement is true. 6 × 3 − 4 × 3 + 16 ÷ 4 = 11
Answer:
The correct statement with parenthesis is (6 × 3) − ((4 × 3 )+ 16) ÷ 4 = 11
Step-by-step explanation:
The statement with parenthesis
(6 × 3) − ((4 × 3 )+ 16) ÷ 4 = 11
On solving we will get
18 - (28÷ 4)
18-7
11
Hence, the correct statement with parenthesis is (6 × 3) − ((4 × 3 )+ 16) ÷ 4 = 11
Determine whether the triangle with the given side lengths is acute,
right, obtuse or not a triangle 3,8,15
Answer:
Step-by-step explanation:
Not a triangle, because the leg lengths 8 and 3 add up to 11, not to 15.
The sum of the leg lengths must be greater than the length of the 3rd side for a triangle to exist.

Which of the following is a non-linear equation?
i) x/3=12
ii) x+1=6
iii) x+y+z=17
iv) xy+x/y=3
Answer:
iv ; xy + x/y = 3
Step-by-step explanation:
A non linear equation is one in which there is no product of two different variables or the same variable
What this mean is that we have the highest polynomial power as 1 or we simply have polynomials of degree 1
Looking at the given options, we can see the product xy
What this mean is that the polynomial is of degree 2 and that makes the equation a non linear as we have a polynomial of more than 1 degree
Mel has a bag containing white and yellow marbles.
Mel randomly selects one marble from the bag,
records the result, and returns the marble to the bag.
The results of the first 65 selections are:
A white marble was selected 41 times
A yellow marble was selected 24 times
Based the on the results, what is the probability that
the next marble Mel selects, rounded to the nearest
percent, will be white?
Answer:
63%
Step-by-step explanation:
A white marble was selected 41 out of 65 times, making the probability of getting white 41/65.
To convert this to percent, divide 41 by 65, then multiply by 100%.
41/65 = 0.630769 = 63% (rounded)

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Arun sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 128 visitors purchased no costume. 3 visitors purchased exactly one costume. 5 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase exactly one costume as a fraction in simplest form.

Write an equation of a line that passes through the point (4, 3) and is perpendicular to the graph of the equation y=-1/3 +4.
Answer:
y=3x-9
Step-by-step explanation:
Hi there!
we are given a point (4,3), and a line (y=-1/3x+4)
Perpendicular lines have slopes that are negative and reciprocal; if they are multiplied together, the result is -1
first, let's find the slope of the new line.
we can find it with this formula: (m=slope)
-1/3m=-1
multiply both sides by -3
m=3
here's our equation so far, written in y=mx+b form, where m is the slope and b is the y intercept
y=3x+b
we need to find b
Because the line passes through the point (4,3), we can use it to find b
substitute x as 4 and y as 3
3=3(4)+b
multiply
3=12+b
-9=b
substitute into the equation
y=3x-9
Hope this helps!

9.5 ×1= 9.5
9.5× 2= 19
9.5× 5= 47.5
These cones are similar. Find the volume of the smaller cone. Round to the nearest tenth. 2 cm 5 cm Volume=[?]cm^ 3 Volume me = 131 cm ^ 3
Answer:
8.4 cm^3 to the nearest tenth.
Step-by-step explanation:
The ratio of the volumes of the 2 cones is the ratio of the cubes of their radii.
So:
5^3 / 2^3 = 131 / v
v = 2^3 * 131 / 5^3
= 8 * 131 / 125
= 8.384.
The volume of smaller cone is 8.4 cm³
What is Volume of Cone?The volume of a cone formula is given as one-third the product of the area of the circular base and the height of the cone. According to the geometric and mathematical concepts, a cone can be termed as a pyramid with a circular cross-section. By measuring the height and radius of a cone, you can easily find out the volume of a cone. If the radius of the base of the cone is "r" and the height of the cone is "h", the volume of cone is given as V = (1/3)πr²h.
By applying Pythagoras theorem on the cone, we can find the relation between volume and slant height of the cone.
We know, h² + r² = L²
⇒ h = √(L² - r²)
where,
h is the height of the cone,
r is the radius of the base, and,
L is the slant height of the cone.
The volume of the cone in terms of slant height can be given as V = (1/3)πr²h = (1/3)πr²√(L² - r²).
Given:
The ratio of the volumes of the 2 cones is the ratio of the cubes of their radii.
Then,
5³ / 2³ = 131 / v
v = 2³ * 131 / 5³
v = 8 * 131 / 125
v = 8.384 cm³
