Is it possible to make the left and right expressions have the same value? Explain your thinking.
Answers
It is possible for equivalent expressions to make the left and right expressions have the same value
What is Expression?
An expression is combination of variables, numbers and operators.
We have to check whether it is possible to make the left and right expressions have the same value
If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
For example 2x+4=2(x+2)
When we plug in x as 2
2(2)+4=2(2+2)
4+4=2(4)
8=8
Hence, its possible to make the left and right expressions have the same value when the expressions are equivalent.

What are similar shape ?
Similar shapes are shapes that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.
Since quadrilateral QRST is similar to quadrilateral WXYZ, then angle Q = angle W , angle R = angle X and angle S = angle Y and angle T = angle Z.
Since angle S is 65° from the diagram shown, angle will be measured as 65°.

The function that represent the balance A in the account after t years is f(t) = 13000( 1.013 )^( 2t ).
This question is incomplete, the complete question is:
Rawan deposits $13,000 into an account that pays 2.6% annual interest compounded every 6 months.
Write a function to represent the balance A in the account after t years.
What is the function that represent the balance A in the account after t years?
The formula accrued amount in a compounded interest is expressed as;
A = P( 1 + r/n )^( n × t )
Where A is accrued amount, P is principal, r is interest rate and t is time.
Given that;
Principal P = $13,000Compounded every 6 months n = 2Interest rate R = 2.6%
First, convert R as a percent to r as a decimal
r = R/100
r = 2.6/100
r = 0.026
Given that time = t.
A = P( 1 + r/n )^( n × t )
f(t) = 13000( 1 + 0.026/2 )^( 2 × t )
f(t) = 13000( 1 + 0.026/2 )^( 2t )
f(t) = 13000( 1 + 0.013 )^( 2t )
f(t) = 13000( 1.013 )^( 2t )
Therefore, the accrued amount after t years is f(t) = 13000( 1.013 )^( 2t ).

Answers
When performing a t-test assuming unequal variances, the test statistic is a t-value, which is calculated by dividing the difference between the means of the two groups by the standard error of the difference.
To see if the difference in mean mpg between 4 and 8 cylinder cars is statistically significant, compare the estimated t-value to a critical t-value based on degrees of freedom and desired level of significance. The difference is regarded statistically significant if the estimated t-value is bigger than the crucial t-value.

what is 62 kilos in pounds
Answers
62 kilograms was found to be equal to approximately 136.7 pounds using conversion formula.
To convert kilograms to pounds, the following formula is used:
Pounds = Kilograms x 2.20462
Plugging in 62 kilograms, we get:
Pounds = 62 x 2.20462
Pounds ≈ 136.7
Therefore, 62 kilograms is approximately equal to 136.7 pounds.
The pound (symbol: lb) is defined as exactly 0.45359237 kilograms, or approximately 16 ounces. There are also different types of pounds, such as the avoirdupois pound (used for general purposes) and the troy pound (used for precious metals).
The kilogram (symbol: kg) is used to measure the mass of an object or substance. For example, it can be used to measure your own body weight, the weight of a bag of groceries, or the mass of a planet. The prefix "kilo-" means "one thousand", so a kilogram is equal to 1,000 grams.

0.4 = 0.167 + 0.2 v.. find the value of v?
Answers
Answer:
v = 1.165
Step-by-step explanation:
To find the value of v in the equation 0.4 = 0.167 + 0.2v, we can isolate v by subtracting 0.167 from both sides:0.4 - 0.167 = 0.2v0.233 = 0.2vNext, we can divide both sides by 0.2 to find the value of v:0.233 / 0.2 = 0.2v / 0.2v = 0.233 / 0.2v = 1.165So the value of v is 1.165.In conclusion, by subtracting 0.167 from both sides of the equation and dividing both sides by 0.2, we found that the value of v is 1.165.
Answer: The value of v that satisfies the equation 0.4 = 0.167 + 0.2v is 1.165.
Step-by-step explanation:
To find the value of v in the equation 0.4 = 0.167 + 0.2v, we can isolate v by subtracting 0.167 from both sides:
0.4 - 0.167 = 0.2v
0.233 = 0.2v
Next, we can divide both sides by 0.2 to solve for v:
0.233 / 0.2 = 0.2v / 0.2
v = 1.165
So, the value of v that satisfies the equation 0.4 = 0.167 + 0.2v is 1.165.
why does the equation y = 3x + 5 not represent a proportional relationship?
Answers
Answer:

comment savoir si un graphique est proportionnelle ?
Answers
Answer:
Pour savoir si un graphique est proportionnel, il faut vérifier si les valeurs de la variable indépendante (l'axe des x) sont proportionnelles aux valeurs de la variable dépendante (l'axe des y). Cela signifie que si on multiplie les valeurs de la variable indépendante par un facteur constant, les valeurs de la variable dépendante seront également multipliées par ce même facteur constant.
Un moyen de vérifier si un graphique est proportionnel est de tracer une ligne droite à travers les points de données. Si tous les points se trouvent sur cette ligne droite, alors le graphique est proportionnel. Si les points ne se trouvent pas sur une ligne droite, alors le graphique n'est pas proportionnel.
Il est également possible de calculer le coefficient de proportionnalité en divisant chaque valeur de la variable dépendante par la valeur correspondante de la variable indépendante. Si le résultat est constant pour toutes les paires de valeurs, alors le graphique est proportionnel.
Enfin, il convient de noter que la proportionnalité n'est qu'un type de relation entre deux variables et que d'autres types de relations peuvent exister, tels que les relations exponentielles, logarithmiques ou quadratiques.

After multiplying and adding given equations, new equations are
3x² + 2xy - 8y² = -273 and 4x - 2y = -32 respectively.
Solutions of the equations are x = -5 and y = 6.
What is linear equation?
A linear equation is an equation in which the greatest power of a variable is always 1. Also called the 1 degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. where x is a variable, A is a coefficient, and B is a constant.
Given equations,
a) x + 2y = 7
b) 3x - 4y = -39
Multiplying both equations
(x + 2y)(3x - 4y) = (7)(-39)
Using Foil method (a+b)(c+d) = ac + ad + bc + bd
3x² - 4xy + 6xy - 8y² = -273
3x² + 2xy - 8y² = -273
Which is a new equation.
Adding both equations
(x + 2y)+(3x - 4y) = (7)+(-39)
Adding like terms, we get
4x - 2y = -32
Solving the equations (a) and (b)
a) x + 2y = 7
x = 7 - 2y
Substituting x in terms of y in equation (b)
b) 3x - 4y = -39
3(7 - 2y) - 4y = -39
21 - 6y - 4y = -39
-10y = -60
y = 6
then x = 7 - 2(6)
⇒ x = - 5
Hence, x = -5 and y = 6 are solutions of given equations.
3x² + 2xy - 8y² = -273 is the equation, after multiplying both equations.
4x - 2y = -32 is equation after both equations are added.

the ________ is the positive square root of the sample variance.
Answers
The standard deviation is the positive square root of the sample variance.
Describe Standard Deviation?
Standard deviation is a measure of the spread or dispersion of a set of data from its mean (average) value. It tells us how much the individual values in a dataset deviate from the average value. In other words, it indicates the extent to which the data points are spread out or clustered around the mean.
The formula for standard deviation is the square root of the variance, which is calculated by finding the average of the squared differences between each data point and the mean. The standard deviation is expressed in the same units as the original data and is denoted by the symbol "σ" for the population standard deviation or "s" for the sample standard deviation.
A small standard deviation indicates that the data points are clustered around the mean, while a large standard deviation indicates that the data points are spread out over a wider range. The standard deviation can be used to determine the range of values within which the majority of the data points lie. For example, if the standard deviation is 2, then about 68% of the data points will be within 2 standard deviations of the mean.
