Answer:
1. 6n - 15
2. x + 10
3. -4d + 15
4. true, associative property
5. distributive, commutative
Step-by-step explanation:
1. distribute 3/4 into the parentheses, so multiply 3/4 * 8 and 3/4 * -20
2. distribute the 2 into the parentheses so multiply 2 * 3x and 2 * 5, then combine like terms
3. distribute -3 into the parentheses so -3 * 4D and -3 * -5 then add like terms
4. add like terms on both sides of the equal sign and you get 10x on both sides. this is the associative property because it doesn't matter what's inside or outside the parentheses you get the same answer no matter how you add them up
5. the first part is distributive because you distributed the three into the parentheses and the second part is commutative because you switch them around and you can get the same answer

6. Write the equation of the line in slope-intercept form given the following:
Point (-4,-4) and Slope of
5/4
Answer:
[tex]y=\dfrac{5}{4}x+1[/tex]
Step-by-step explanation:
Slope intercept form a equation of a line is given by the following formula:
Slope intercept form:
[tex]y=mx+c[/tex]
Given that, a point is (-4,-4)
i.e.
[tex]x=-4,\\y=-4[/tex]
Slope, [tex]m =\frac{5}{4}[/tex]
Putting the given values in the Slope intercept form equation:
[tex]-4=-4\times \dfrac{5}{4}+c\\\Rightarrow -4=-5+c\\\Rightarrow c =1[/tex]
Putting the value of [tex]c[/tex] and [tex]m[/tex] in the slope intercept form:
[tex]y=\dfrac{5}{4}x+1[/tex]
T is 375 miles from San Francisco to Los Angeles. On a map of California, the scale shows that 2 centimeters equals 10 actual miles. How far apart on the map are the two cities?
Answer:
75 cm
Step-by-step explanation:
the ratio of centimeter to miles is 2:10 or 1:5 (1 cm = 5 mi)
this ratio can be changed to a fraction (1/5)
so now we can set up this equation:
(1/5) = (x/375)
where x = cm on the map
if it makes it easier to understand:
(1cm/5mi) = (xcm/375mi)
now we solve for x:
375(1/5) = x
x = 375/5
x = 75 cm

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

The area of a rectangular door is 21 ft. Sq. The border around the door is 20 feet. What is the length and width of the door? Use the factors of 21 to help you find the area of the door first.
Answer:
Length = 7 feet, and width is 3 feet.
Step-by-step explanation:
For the given rectangular door,
area = length x width
21 = length x width ................. 1
Also,
perimeter = 2 ( length + width)
20 = 2 ( length + width)
10 = length + width ............ 1
Given that the factors of 21 are required to get the are of the door.
Then, from equation 1;
21 = 7 x 3
And from equation 2;
10 = 7 + 3
So that, the length of the door is 7 feet and its width is 3 feet.

A sign on the road says: "Speed limit, 60 miles per hour."Let s be the speed of a car. Write an inequality that matches the information on the sign .Could 60 be a value of s? Explain your reasoning.
Answer:
s ≤ 60 mphStep-by-step explanation:
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.

Step-by-step explanation:
A pilot takes a taxi from the airport and the hotel. The taxi driver charges a $2.50 fee plus $2.65 per mile. Write an equation that can be used to find y, the total cost of the trip, if x represents the number of miles on the trip.
Answer:
2.50 + 2.65x = y
Step-by-step explanation:
The 2.50 fee won't change but the price per mile will, each mile will cost $2.65 more. And since we don't know how many miles the plot is taking, $2.65x. Then the total cost is y
Answer:
Step-by-step explanation: if the 2.50 is staying the same, then the answer is y=2.50x + 2.65

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]

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.

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.
