your uncle is 2 years older than your 3 times your age. a. you are x old. write an expression to describe your uncle's age. b. you are 12 years old. how old is your uncle
The age of your uncle is modeled by:
y = 2 + 3*x
Evaluating it, we can see that when you are 12 years old, your uncle will be 38 years old.
How to find the equation for your uncle's age?Let's define the variables: y as your uncle's age and x as your age.
Here we know that your uncle is 2 years older than 3 times your age, so we can write the linear equation:
y = 2 + 3*x
This is the equation we needed to find.
b) If you are 12 years old, then we can write x = 12 in the equation above, then we will get:
y = 2 + 3*12
y = 2 + 36
y = 38
That's the age of your uncle.

In 33,291 how is the value of the three in the 10,000s place related to the value of the three in the thousands place
The place value of 3 in 10,000s place is the product of 10 with the place value of 3 in thousands place.
What is Place Value?Every digit in a number has it's own place value. Place value is the position of a digit in a number.
For example, in the number 3456, 6 is in the ones place, 5 is in the tens place, 4 is in the hundreds place and 3 is in the thousands place.
Given the number 33,291.
Place value of 1 = 1
Place value of 9 = 90
Place value of 2 = 200
Place value of 3 in thousands place = 3000
Place value of 3 in ten thousands place = 30,000 = 3000 × 10
That is, place value of 3 in 10,000s place is the product of ten with the place value of 3 in thousands place.
Hence the place value of 3 in thousands place multiplied to 10 gives the place value of 3 in 10,000s place.

What is the coefficient of x³?
Let x equal the x³-1 coefficient. Thus, x=1 is the coefficient of the given function.
Coefficient definition.
A number or symbol that multiplies another number or symbol is referred to as a "coefficient" (used as a mathematical variable).
Give a co-efficient example in writing.
A coefficient is a result of multiplying an amount by a variable. 6z, for instance, is short for six times z. 6 is a coefficient since z is a variable. The coefficient is one for variables that don't have a value.
Let x equal the x³-1 coefficient. Thus, x=1 is the coefficient of the given function.
The expression's coefficient is the term multiplied by x³. Since x³ is not a word, the answer is 1.

Is it possible for two lines with negative slopes to be perpendicular? Justify your answer.
Answer:
No
Step-by-step explanation:
The slopes of perpendicular lines must always be the negative reciprocal of each other. If one slope is negative, for the other to be perpendicular to it, it must be positive, and vise versa.
Answer:
No
Step-by-step explanation:
Interesting question. Subtle.
The formula for two lines to be perpendicular is m1 * m1 = -1 That means that two lines cannot be minus -- only 1 of them can be. The reason is that if both were minus when multiplied together would give a positive result -- not minus one. For example, suppose you have
y = x + 2
y = 2x + 3.
These 2 lines will cross and they are not parallel, but neither are they perpendicular. I'm not going to solve this to find out where they cross -- that's not what you are asking.
Now suppose you have two other lines
y = - 2x + 3
y = 1/2 x + 1
These two lines should be perpendicular
-2 * 1/2 = - 1 which is the condition of perpendicular.

There are 30 students in an art class. Fourteen of the students are girls.
What is the ratio of boys to girls?
A.7:8
B.8 :7
C.8:15
D.14:40
E.30:14
Answer: B
Step-by-step explanation: To get the boys part of the ratio you will have to subtract 30 students and 14 students that are girls because all together there are 30 students and since we only know that 14 of them are girls that leaves the rest of the students boys. 30 - 14 = 16 so now we know how many boys there are. 16:14 can be reduced by 2 and that equals to 8:7.
Hope this helps!
The ratio of boys to girls is equal to: B. 8 :7
Given the following data:
Total students = 30 studentsNumber of girls = 14 studentsTo calculate the ratio of boys to girls:

Data on the fuel consumption y of a car at various speeds x is given. Fuel consumption is measured in mpg, and speed is measured in miles per hour. Software tells us that the equation of the least‑squares regression line is ^ y = 55. 3286 − 0. 02286 x
Fuel consumption is 53.957 miles per gallon for a car moving at a speed of 60 miles per hour using least square Regression .
What is Regression ?A statistical word for models that evaluate the connections between variables is regression. A single dependent variable Y and one or more independent variables X are studied using a linear regression model.
A technique for employing a goodness-of-fit criterion to fit a curve—not necessarily a straight line—through a collection of points. Regression that is most frequently used is linear regression. Recursion is occasionally used interchangeably with the word regression.
Y = mX + b, where X is the predictor (independent) variable, m is the estimated slope, and b is the expected intercept, is the formula for simple linear regression.
Calculation of Fuel Consumption in 60 miles per hour.
given the least square regression line is
y = 55.3286 - 0.02286x

How do you find the X and y-intercept of a function?
To find the x-intercept and y-intercept of a function, one can set the x or y value equal to zero and solve for the other variable.
The x-intercept of a function is the point where the graph of the function crosses the x-axis. To find the x-intercept, one can set the y-value equal to zero and solve for the x-value. For example, if the function is y = 2x + 3, the x-intercept can be found by setting y equal to zero and solving for x. In this case, 0 = 2x + 3, which means x = -3/2. So the x-intercept of this function is (-3/2,0).
The y-intercept of a function is the point where the graph of the function crosses the y-axis. To find the y-intercept, one can set the x-value equal to zero and solve for the y-value. For example, if the function is y = 2x + 3, the y-intercept can be found by setting x equal to zero and solving for y. In this case, y = 2(0) + 3 = 3, so the y-intercept of this function is (0,3).
Knowing the x and y intercepts of a function gives an idea of where the graph will start and the behavior of the function in the x and y-axis.

How do you know if 3 lengths will make a triangle?
If three lengths can make a triangle by using the Triangle Inequality Theorem which states . that any two triangle sides added together must exceed the third side If the sum of any two sides is equal to or less than the third side, then the lengths cannot make a triangle.
The Triangle Inequality Theorem can be used to determine if a triangle can be formed from three lengths. According to this theorem, any two triangle sides must add up to more than the third side. To put it to use, add up the lengths of the first two sides and compare them to the third side's length. The lengths cannot form a triangle if the total of the first two sides is more than or equal to the third side. The lengths can form a triangle if the product of the first two sides is bigger than the product of the third side.

The experimental calculation of the specific heat of aluminum was found to be. 156 cal/g °C, but the actual value was given as. 185 cal/g °C. What is the percent error?
The percentage error is 16%
We know that the formula for the percentage error.
E = (absolute error / actual value) × 100
The formula for the absolute error is:
A = |actual value - experimental value|
A = |V1 - V2|
where V1 is the actual value
V2 is the experimental value
E is the percentage error
A is the absolute error
In this question, the experimental calculation of the specific heat of aluminum = 156 cal/g °C
And the actual specific heat of aluminum = 185 cal/g °C
Using above formula of absolute error,
A = |185 - 156|
A = 29 cal/g °C
And the percent error would be,
E = (absolute error / actual value) × 100
E = (29 / 185) × 100
E = 0.16 × 100
E = 16%

If c represents the total cost in dollars and cents of the juice for any number, j, of bottles of juice, write a proportional equation for c in terms of j that matches the context. How do I do that
The proportion equation for c in terms of j is written as c = 0.9j
How to write the equationIn order to find the proportional equation for c in terms of j that matches the context, what you would have to do would be to divide 9.90 dollars by 11 bottles of pineapple juice.
This would tell us the price that one of the bottles of juice is been sold for.
Hence we would have
