Step-by-step explanation:
Kayden's math teacher said that each question answered correctly on a test would be worth 7 points. Answer the questions below regarding the relationship between the number of questions correct and the score on the test.
Since 00 questions correct gets you 00 points on the test, the function will have a yy-intercept of 0.0.
The rate at which points are earned is 7 points per question, so the slope of the function should be 7.7.
\text{Function Rule:}
Function Rule:
V(x)=7x
V(x)=7x
Plug x=11 Into Rule:
V(11)=7(11)=77
Correct Answer:
The independent variable, x, represents the number of questions correct, and the dependent variable is the score on the test, because the score on the test depends on the number of questions correct.
A function relating these variables is V(x) =V(x)= 7x7x.
So V(11) =V(11)= 7777, meaning 1111 questions correct will earn 7777 points on the test

The denominator of a fraction is 2 more than the numerator. If 1 is added to both, the fraction reduces to 4/5. Find the fraction
The fraction is 7/9 according to given information.
What is fraction?
A fraction, which derives from the Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal parts. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many parts of a particular size there are when spoken of in everyday English. A common, vulgar, as well as simple fraction is one that has a non-zero denominator displayed below (or after) the line that separates the numerator from the denominator. Compound fractions, complex fractions, as well as mixed numeral fractions are examples of uncommon fractions that use numerators and denominators.
Main Body:
Let the fraction be a/b
In First condition
b = a + 2(1)
In Second condition
a + 1/b + 1 = 4/5
5(a + 1) = 4(b + 1)
5a + 5 = 4b + 4
5a - 4b = 4 - 5
5a - 4b = -1
Using 1
5a - 4(a + 2) = -1
5a - 4a - 8 = -1
a = 8 - 1
a = 7
Now,
Using 1
b = a + 2
b = 7 + 2
b = 9
Fraction = a/b = 7/9
hence , the fraction is 7/9.

g(x) −36 −26 −11 9 14
(0, 4)

(0, 8)
(0, −8)
The y-intercept of (f − g)(x) is 8. Therefore, option C is the correct answer.
Given various values of the linear functions f (x) and g(x) in the table.
What is a y-intercept?An intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
For the function f(x)
Here, (-6, 20) and (-4, 14)
Slope =(14-20)/(-4+6)
= -3
Substitute, m=-3 and (x, y)=(-6, 20) in y=mx+c, we get
20=-3(-6)+c
c=2
Substitute, m=-3 and c=2 in y=mx+c, we get
f(x)=-3x+2 --------(I)
For the function g(x)
Here, (-6, -36) and (-4, -26)
Slope =(-26+36)/(-4+6)
= 10/2 =5
Substitute, m=5 and (x, y)=(-6, -36) in y=mx+c, we get
-36=5(-6)+c
c=-6
Substitute, m=5 and c=-6 in y=mx+c, we get
g(x)=5x-6 --------(II)
Now, (f − g)(x)=-3x+2-(5x-6)
= -3x+2-5x+6
= -8x+8
Here, y-intercept is 8
The y-intercept of (f − g)(x) is 8. Therefore, option C is the correct answer.

What is slope of a line?
A line's steepness and direction are measured by the line's slope. A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, Δy, Δx respectively. Consequently, it is possible to write the change in y coordinate with respect to the change in x coordinate as m = Δy/Δx
Given equation of line r is y = 6/7x+1.
The slope of line r is m = 6/7
The slope of the line that is perpendicular to line r is -1/m = - 7/6.
The equation of line that passes through the point (x₁, y₁) with slope m is y - y₁ = m(x - x₁).
Putting m = - 7/6, x₁ = 7 and y₁ = -7 in y - y₁ = m(x - x₁):
y - (-7) = - 7/6(x - 7)

Rex deposited $900 into an

The number of years for the value of $900 to reach $1,800 if the rate of interest is 4%, is 25 years.
What is interest?When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.
Given:
The amount after some years, A = $1800,
The rate of interest, r = 4% per annum,
The principal amount, p = $900,
Calculate the number of years as shown below,
A = P + SI
1800 = 900 + p × r × t / 100
Here, t is the time in years,
1800 - 900 = 900 × 4 × t / 100
900 = 3600t / 100
900 = 36t
t = 900 / 36

after 3 days a sample of radon-222 has decayed to 58% of its original amount. (a) what is the half-life of radon-222? (b) how long will it take the sample to deca
The half-life of radon-222 is 3 days, it will take an additional 3 days for the remaining 42% of the sample to decay, for a total of 6 days for the sample to decay completely.
What is half life of an element?The half-life of a radioactive is time for 50% of its particles to decay or disintegrate into a new element. The pace at which a radioactive material will decay is predicted using this indicator of an isotope's stability. An element's half-life, which differs substantially across various elements, is based on the unique characteristics of its nucleus.
For instance, the half-life of uranium-238 is 4.5 billion years whereas that of carbon-14 is 5,730 years. This indicates that half of the carbon-14 atoms in a sample will have decayed after 5,730 years, and half of the uranium-238 atoms will have decayed after 4.5 billion years.
How to solve?
(a) After 3 days, the sample has decayed to 58% of its original amount, which means that half of the original amount has already decayed. Therefore, the half-life of radon-222 is 3 days.
(b) Since the half-life of radon-222 is 3 days, it will take an additional 3 days for the remaining 42% of the sample to decay, for a total of 6 days for the sample to decay completely.

Answer: The answer is here
Step-by-step explanation:
If the two sides of a triangle are in the same proportion of the two sides of another triangle, and the angle inscribed by the two sides in both the triangle are equal, then two triangles are said to be similar. Thus, if ∠A = ∠X and AB/XY = AC/XZ then ΔABC ~ΔXYZ.

The amount of medicine required for a patient whose weight is 173.75 pounds will be equal to 217.18 milligrams.
What is the ratio?The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities to compare them.
As per the data given in the question,
Weight of patient = 164 pounds
Medicine for 164 pounds weight = 205 milligrams
Weight of another patient = 173.75 pounds
