On a recent test, you were given the table displayed and
asked to write the rule that models it.
What should the rule be for the table?
O Subtract 6 from the x value to get the y value.
O Multiply the x value by 1/2 to get the y value.
O Multiply the x value by 1/4 to get the y value.
O Add 6 to the value to get the y value.
9514 1404 393
Answer:
A. Subtract 6 from the x value to get the y value.
Step-by-step explanation:
Sometimes, it works well to simply try the answers to see what works. Sometimes, it works better to use a point other than the first or second.
Using the last point (x, y) = (16, 10), we can try the rules:
subtract 6 from x: 16 -6 = 10 . . . this rule works
multiply by 1/2: 16×1/2 = 8, not 10 . . . doesn't work
multiply by 1/4: 16×1/4 = 4, not 10 . . . doesn't work
add 6 to x: 16 +6 = 22, not 10 . . . doesn't work
The only rule that works is ...
Subtract 6 from the x value to get the y value.

Additional comments
You cannot always assume the table represents a linear function. In this case, all of the answer choices are linear functions, so that is a reasonable assumption. The x-values all have the same difference: 4. The y-values also all have the same difference: 4. So the slope of the line is 4/4 = 1, which tells you right away that "multiply by 1/2" and "multiply by 1/4" will be wrong.
The x-values are all greater than the y-values, so "add 6 to the x value" will not be correct. Since the slope is 1, the difference between x and y will be a constant, easily found from any table entry.
y = x + b . . . . equation of a line with a slope of 1
2 = 8 + b . . . . using the first table entry
-6 = b . . . . . . . subtract 8
Then ...
y = x - 6

Jarvis bought 2 beach towels and 3 pairs of swim trunks at a retail store. Each beach towel costs $3 less than a pair of swim trunks. He spent a total of $79. Let s represent the cost of a pair of swim trunks.
Part B
Add the two expressions and set this sum equal to 79 to model the situation with an equation. Solve for s . What is the cost of one pair of swim trunks?
A) The equation that represents the cost of a pair of swim trunks is;
2(s - 3) + s = 79
B) The cost of a pair of swim trunks is; $28.33
How to solve Algebra Word Problems?Algebraic word problems are defined as questions that require translation of sentences to equations, and thereafter solving those equations.
Let the cost of one pair of swim trucks be s.
We are told that Each beach towel costs $3 less than a pair of swim trunks. Thus;
Cost of each beach trunk = (s - 3)
Jarvis bought 2 beach towels and 3 pairs of swim trunks at a retail store. Thus, we have;
2(s - 3) + s = 79
2s - 6 + s = 79
3s = 79 + 6
3s = 85
s = 85/3
s = $28.33

martha invested $41.25 into a company. if each share was worth $1 1/4 how many shares did Martha invest in the company
Answer: 33 shares
Step-by-step explanation:
Amount invested in the company = $41.25
Price per share = $1 1/4 = $1.25
To calculate the amount of shares that Martha invested in the company will be:
= Amount invested in the company/Price per share
= $41.25/$1.25
= 33 shares
Martha invested 33 shares in the company.

Lisa wanted to study how the area of a rectangle changes with the length if it’s width is fixed. She computed the areas of several rectangles that have the same width and different lengths. She then employed the results and connected them with a line, as shown in the picture. The graph shows the area (in m2) versus the length (in m)
a. Domain:
b. Range
(Sorry I keep asking so many questions it’s because these questions are questions of things I have NEVER learned at all yet and it is a new module. When people explain and show me the work I write them in my book with the explanations as well when people put them down and that is how I start to learn this ahead of time.)
Answer:
Domain: interval: [0,∞], Words: All real numbers greater than or equal to 0, Inequality: x≥0.
Range: interval: [0,∞], Words: All real numbers greater than or equal to 0, Inequality: y≥0.
The domain and range of the function shown is
domain [tex]x\geq 0[/tex]
range [tex]y\geq 0[/tex]
Given :
The graph of the area of a rectangle changes with the length if it’s width is fixed
We need to find out the domain and range from the given graph
Domain is the set of x values on the graph
We can say the graph starts at x=0 and it goes up to infinity
So, domain is [tex]x\geq 0[/tex]
Range is the set of y values for which the function defined
Range is the set of y values on graph
When we look at y values , the graph starts at y=0 and it goes up to infinity
So, range is [tex]y\geq 0[/tex]

Answer:
a = - 3
Step-by-step explanation:
The equation has common factors x(x + 3) on both sides
For the 2 sides of the equation to be equal, then the factor
(x + a) = (x - 3) and by comparison
a = - 3

Given A(2, 3), B(8, 7), C(6, 1), which coordinate will make line AB perpendicular to line CD?
D(9, 3)
D(4, 4)
D(3, 3)
D(8, 4)
Answer:
The correct option is;
D(4, 4)
Step-by-step explanation:
The given coordinates of the points are, A(2, 3) B(8, 7), C(6, 1), therefore, the coordinates of the point D that will make CD perpendicular to AB will have a slope = -1/m, where, m = the slope of the line segment AB
The formula for finding the slope, m, of a segment, given the coordinates of two points on the straight line segment (x₁, y₁), (x₂, y₂)
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, for, the segment AB, we have;
m = (7 - 3)/(8 - 2) = 4/6 = 2/3
m = 2/3
Therefore, to make the segment AB perpendicular to the segment CD, the slope of the segment CD will be -1/m = -1/(2/3) = -3/2
The equation of the segment CD in point and slope form is therefore;
y - 1 = -3/2×(x - 6)
y - 1 = -3·x/2 + 9
The standard form of the equation of the segment CD is therefore;
y = -3·x/2 + 9 + 1 = -3·x/2 + 10
y = -3·x/2 + 10
The point that satisfies the above equation is the point (4, 4) because;
4 = -3 × 4/2 + 10
The correct option is therefore, D(4, 4).

The quadratic function f(x) has real coefficients. Given that f(3 - 2i) = 0, what must be the
other solution to the equation f(x) = 0 ?
Answer:
Option (C)
Step-by-step explanation:
Conjugate root theorem:
If (a - bi) is a root of a polynomial with real coefficients, then (a + bi) will be the other root.
By this theorem, if (3 - 2i) is one root of the quadratic function 'f', other root will be (3 + 2i).
Therefore, x = (3 + 2i) will be the other root.
Option (C) will be the answer.

Speed limit is given in order not to exceed it
Therefore the equation would be:
s ≤ 60 mphs = 60 is allowed as per the equation, since you are not exceeding this speed. As per the rule, s = 60 mph is the maximum speed at which the vehicle is permitted to travel.
