Jose made this table to show the relationship between his age and his cousin Mario's age.
Jose wants an equation he can use to find his own age (j) given Mario's age (m).
Complete Jose's equation:
y=_____
Thanks so much have a good day!
The equation that can be used to determine Jose's age given Mario's age is j = [tex]3\frac{1}{3}[/tex]m
What is the equation?Th relationship between Jose's age and Mario's age can be modelled as a linear equation. A linear equation is an equation that when graphed is a straight line. The straight line can either slope upward or downward.
A linear equation is an equation that increases at a constant rate. It has a single variable that is raised to the power of one.
Looking at the table, there is a proportional relationship between Jose's age and Mario's age.
A proportional relationship has this form: j = bm
Where:
j = Jose's age m = Mario's age b = constant of proportionality10 = b3
b = 10 / 3
b = 3 1/3
j = [tex]3\frac{1}{3}[/tex]m

a + b - 8 = p solve for a
Answer:
a = −b + p + 8
Step-by-step explanation:
a + b - 8 = p solve for a
a + b - 8 = p
subtract b from both sides:
a + b - 8 - b = p - b
a - 8 = p - b
add 8 to both sides:
a - 8 + 8 = p - b + 8
a = p - b + 8
rearrange for alphabetical order:
a = −b + p + 8
Answer:
a = p + 8 - b
Step-by-step explanation:
Step 1: Add 8 both sides
[tex]\displaystyle{a+b-8+8=p+8}\\\\\displaystyle{a+b=p+8}[/tex]
Step 2: Subtract b both sides
[tex]\displaystyle{a+b-b=p+8-b}\\\\\displaystyle{a=p+8-b}[/tex]
Note: You can also subtract b both sides first then add 8 both sides.
Therefore, the new equation when a-term is the subject is [tex]a=8+p-b[/tex].

By applying a rotation of 180° counterclockwise to triangle ABC, we have the following:
The ordered pair for A' is (4, 0).The ordered pair for B' is (7, 2).The ordered pair for C' is (9, 9).What is a rotation?A rotation can be defined as a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.
In Geometry, rotating a point 180° about the origin in a clockwise or counterclockwise (anticlockwise) direction would produce a point that has the coordinates (-x, -y).
By applying a rotation of 180° counterclockwise (anticlockwise) to triangle ABC, the coordinate of the image of triangle A'B'C' is given by:
(x, y) → (-x, -y)
Points at A = (-4, 0) → Points at A' = (-(-4), -(0)) = (4, 0)
Points at B = (-7, -2) → Points at B' = (-(-7), -(-2)) = (7, 2).
Points at C = (-7, -2) → Points at C' = (-(-9), -(-9)) = (9, 9).

Find the Standard deviation of 2, 2.6, 3.2, 4.3 5, 4.7, 6.2
The most appropriate choice for standard deviation will be given by-
Standard deviation is 1.41
What is Variance and standard deviation?
At first, it is important to know about mean of a data.
Mean gives the average value of the data.
Variance is calculated by taking the sum of the square of deviation of each value of the data set and then dividing the sum by the total number of values of the data set.
On taking the square root of the variance, we will obtain the standard deviation of the data set.
Here,
The data set is 2, 2.6, 3.2, 4.35, 4.7, 6.2
Mean = [tex]\frac{2 + 2.6 + 3.2 + 4.35 + 4.7 + 6.2}{6}[/tex]
= 3.84
Variance = [tex]\frac{(2-3.84)^2+(2.6-3.84)^2+(3.2-3.84)^2+(4.35-3.84)^2+(4.7-3.84)^2+(6.2-3.84)^2}{6}[/tex]

Let [tex]ax^2+bx +c[/tex] be a quadratic equation (a ≠ 0)
Then
[tex]x = \frac{-b \pm \sqrt{b^2 -4 \times a \times c}}{2\times a}[/tex]
Here,
Let the width of the safety zone be x metre
Length of rectangular park = 50m
Breadth of rectangular park = 30m
Area of rectangular park = [tex]50 \times 30[/tex]

Length of rectangular park with safety zone = (x + x + 50) m

Diana severs breakfast to two groups of children at a daycare center. One box of Oaties contains 12 cups of cereal. She needs ⅓ cup for each younger child and ¾ cup for each older child. Is one box of Oaties enough for everyone
One box of oaties will be enough for two groups of children.
We can state the box of oaties is enough for everyone, if the amount required by number of children in each group is less than or equal to 12.
So, amount of cereal required by younger/older children = amount required by one child × number of children
Amount of cereal required by younger children = 1/3 × 11
Amount of cereal required by younger children = 11/3 cups of cereal
Amount of cereal required by older children = 3/4 × 10
Amount of cereal required by younger children = 15/2 cups of cereal
Amount of cereal = 12 - (11/3 + 15/2)
Taking LCM in the bracket, we get 6
Amount of cereal = 12 - (11×2 + 15×3/6)
Solving the bracket
Amount of cereal = 12 - (22 + 45/6)
Performing addition = 12 - (67/6)
Amount of cereal = (12×6 - 67)/6
Amount of cereal = 72 - 67/6
Performing subtraction in numerator
Amount of cereal = 5/6
As 5/6 cups of cereal is remaining, thus, a box of oaties will be enough for 11 younger children and 10 older children.

Prove that the measures of the exterior angles of a triangle have a sum of 360°.
Given: <1, <2, and <3 are exterior angles.
Prove: m<1 +m<+m<3 = 360
Sum of Exterior Angles of Triangle is 360°.
Define Exterior Angle
The angle between any side of a shape and a line that extends from the next side is known as the exterior angle.
Let's Prove: ∠1 + ∠2 + ∠3 = 360°
The angle that is created between one of a triangle's sides and its adjacent extended side is known as the external angle. A triangle has three external angles. Let's learn about the equation for adding a triangle's exterior angles.
From the figure, we can observe that ∠1, ∠2, and ∠3 are the exterior angles of triangle ABC. We know that the sum of all the exterior angles of any polygon is equal to 360°.
Thus, sum of all the exterior angles of a triangle = 360°

The distinction among rational numbers as well as fractions is that fractions cannot include a negative denominator or numerator. As a result, the numerator and denominator of the a fraction are all numbers (denominator 0), whereas the numerator and denominator of rational numbers are integers.A rational number, p/q, is considered to be in standard form if its numerator and denominator (p and q) share no common divisor (or factor) other than 1 and its denominator "q" is positive.For the given number-
π, 5/4, -8, 2.35 bar, 19/7, 8, 0
All numbers except π are rational as they are either ending number or have the bar which means they will repeat after some point.
π is the only number which have the value 3.14........and so o such that, it is nether terminating nor repeating.
Thus, π is the irrational number.

An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, but in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign. Solving an equation with variables entails finding which variables' values make the equality true. The variables for which the equation must be solved are also known as unknowns, and the values of the unknowns that fulfill the equality are known as equation solutions. Identity equations and conditional equations are the two types of equations.
