What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Fatimah ate f treats. Satvinder ate six less than twice the number that Fatimah ate.
Let 's' be the number of cookies eaten by Satvinder. Then the equation is given as,
s = 2f - 6
If Satvinder ate 4 cookies, then the number of cookies that Fatimah ate will be given as,
4 = 2f - 6
2f = 10
f = 5
On the off chance that Satvinder ate 4 treats, the number of treats that Fatimah ate will be 5.

Which polynomial is prime?
O x² +7
Ox²-25
O3x²-27
O 2x²-8
Explanation:
All of the polynomials listed are quadratic polynomials, which have the general form ax^2 + bx + c, where a, b, and c are constants and x is a variable. A polynomial is considered prime if it cannot be factored into the product of two or more polynomials with integer coefficients.It is not possible to determine whether any of the given polynomials are prime without further information, such as the values of the constants a, b, and c. For example, the polynomial x^2 + 7 could be prime, but it could also be factored into the product of two linear polynomials (x + 3)(x + 3), which would make it composite. Similarly, the polynomial x^2 - 25 could be prime, but it could also be factored into the product of two polynomials of the form (x + 5)(x - 5), which would make it composite. Without more information, it is not possible to determine whether any of the given polynomials are prime.

The functions for this problem are classified as follows:
Land: Linear function.Car: Linear function.How to classify a function as exponential or linear?A function is classified as exponential if when the input variable is changed by one, the output variable is multiplied by a constant.
A function is classified as linear if when the input variable is changed by one, the output variable is increased/decreased by a constant.
For the land function, the rates are given as follows:
36.9/30 = 1.23.44.1/36.9 = 1.20.51.1/44.1 = 1.16.58.1/51.1 = 1.14.The differences are given as follows:
36.9 - 30 = 6.9.44.1 - 36.9 = 7.2.51.1 - 44.1 = 7.58.1 - 51.1 = 7.Neither are exactly the same, however the variations for the differences are less, meaning that it can be classified as a linear function.
For the car, the rates are given as follows:
12.1/9 = 1.344.15/12.1 = 1.24.17.9/15 = 1.19.20.9/17.9 = 1.17.The differences are given as follows:

Justin is going to invest $90,000 and leave it in an account for 19 years. Assuming
the interest is compounded quarterly, what interest rate, to the nearest hundredth of
a percent, would be required in order for Justin to end up with $216,000?
Answer:
4.63%
Step-by-step explanation:
You want the interest rate that, compounded quarterly, will result in a balance of $216,000 for an investment of $90,000 after 19 years.
Compound interestThe formula for the balance of an account earning compound interest is ...
A = P(1 +r/n)^(nt)
where P is the principal invested, r is the annual interest rate, n is the number of times per year interest is compounded, and t is the number of years.
ApplicationFilling in the given values, we can solve for r:
216000 = 90000(1 +r/4)^(4·19)
2.4 = (1 + r/4)^76 . . . . . divide by 90,000
2.4^(1/76) = 1 +r/4 . . . . . . take the 76th root
(2.4^(1/76) -1) = r/4 . . . . . . subtract 1
r = 4(2.4^(1/76) -1) ≈ 0.0463437 ≈ 4.63%
The required interest rate is about 4.63%.
Simplify 4x - 7 + 12x - 3.

Mango Used Smoothie Size
Kim 1 8 oz
Bri 3 24 oz
Angela 4 32 oz
Which statement is correct based on the data?
The statement that is correct based on the data is that the table shows a proportional relationship
How to determine the true statementFrom the question, we have the following parameters that can be used in our computation:
Mango Used Smoothie Size
Kim 1 8 oz
Bri 3 24 oz
Angela 4 32 oz
Express properly
So, we have
Mango Used Smoothie Size
Kim 1 8 oz
Bri 3 24 oz
Angela 4 32 oz
Start by checking if the table has a constant rate
This is represented as
Constant rate = Smoothie Size/Mango Used
So, we have
Constant rate = 8/1 = 8
Constant rate = 24/3 = 8
Constant rate = 32/4 = 8
See that the constant rate is the same for all values
Hence, the table shows a proportional relationship

A study is conducted to see if a daily exercise intervention affects blood pressure among people with pre-hypertension. The study design being used is a randomized controlled trial (RCT).
What is a randomized controlled trial?Generally, In an RCT, the study participants are randomly assigned to either the intervention group or the control group. This helps to ensure that any differences between the two groups are not due to preexisting differences between them, but rather are due to the intervention being tested.
In this case, the intervention is a daily exercise intervention, and the outcome being measured is blood pressure among people with pre-hypertension.
The control group serves as a comparison group, and any changes in blood pressure observed in the intervention group can be attributed to the intervention rather than other factors.
