____(3 + 4) = 36 + 48
Answer:
12 will come in the blank
Step-by-step explanation:
Distributive property is used
a(b + c) = a*b + a*c
36 + 48 = 12*3 + 12*4
= 12(3 + 4)
When Hana goes to the mall, she always buys the same lunch and also buys some books. The table shows the number of books she buys, x, and the total amount of money she spends, y.
x 1 2 3 4 5
y 17 21 23 26 34
If this data were displayed in a scatter plot, select ALL statements that would be true about a good trend line summarizing the data.
Group of answer choices
The slope approximates the cost of Hana's lunch.
The y-intercept approximates the average cost of one book.
The y-intercept approximates the cost of Hana's lunch.
The slope approximates the average cost of one book.
The trend line goes through the origin.
Scatter plots are used to represent data of dual numerical values.
The true statements about the scatter plot of Hana's purchase are:
The slope approximates the average cost of one book. The y-intercept approximates the cost of Hana's lunch.I've added as an attachment, the scatter plot that represents Hana's purchase.
From the attached plot, we have the following observations
The x-axis represents the number of booksThe y-axis represents the amount spentBecause the x-values represents the number of books, the slope of the graph would represent the cost of a book.
The amount spent on a meal is constant;
This amount can be gotten when the number of books is 0;
In other words, the y-intercept represents the cost of Hana's meal.
Hence, the true statements are: (c) and (d)

Help! GHJ Café sells Medium and large coffees to locals in Downtown Dallas. If 7 medium cups and 10 large cups of coffee are sold, the café makes $68.75 in sales. If 10 medium and 15 large cups are sold, the total sales is $101.25. How much does a large cup of coffee sell for at GHJ Café?
Answer:
Large cup cost $4.25
Step-by-step explanation:
Medium: x
Large: y
Constraints:
7x + 10y = 68.75
10x + 15y = 101.25
Isolate y variable:
(7x + 10y = 68.75) * -10 ===> -70x - 100y = -687.50
(10x + 15y = 101.25) * 7 ===> 70x + 105y = 708.75
____________________
add the two equations 5y = 21.25
divide by 5 y = 4.25

Answer:that’s too hard
Step-by-step explanation:
log x = log(x + 3) - log(x - 1)
First note that log(x) is defined only for x > 0; log(x + 3) for x > -3; and log(x - 1) for x > 1. So if we find any solutions x ≤ 1, these will be extraneous.
Condense the right side:
log(x) = log((x + 3) / (x - 1))
Let b be the base of the logarithm. Then writing both sides as powers of this b simplifies the equation to
b^log(x) = b^log((x + 3) / (x - 1))
x = (x + 3) / (x - 1)
Solve for x :
x (x - 1) = x + 3
x ² - x = x + 3
x ² - 2x - 3 = 0
(x - 3) (x + 1) = 0
x - 3 = 0 or x + 1 = 0
x = 3 or x = -1
We throw out x = -1 because it's less than 1, so the only (real) solution is x = 3.

Have to find x and y . Please help!
Answer:
Step-by-step explanation:
x can be anything so let’s use 0, 1, 2, and 3 for x values
to find the y values, we just plug in the x values into the equation
when x = 0
y = 5/4(0) -2
y = 0 -2
y = -2
(0, -2) (x = 0, y = -2)
when x = 1
y = 5/4(1) -2
y = 5/4 -2
y = 5/4 -8/4
y = -3/4
(1, -3/4) (x = 1, y = -3/4)
when x = 2
y = 5/4(2) -2
y = 10/4 -2
y = 5/2 -4/2
y = 1/2
(2, 1/2) (x = 2, y = 1/2)
when x = 3
y = 5/4(3) -2
y = 15/4 -2
y = 15/4 -8/4
y = 7/4
(3, 7/4) (x = 3, y = 7/4)
Answer:
Table shown below
Step-by-step explanation:
Table of Values
We are given the function:
[tex]\displaystyle y=\frac{5}{4}x-2[/tex]
And it's required to fill the table of values for x and y with the condition that there are only integers.
Given the expression has a denominator of 4, to ensure there are no decimals in the results, we select values of x that are multiple of 4.
Select the values: {-4,0,4,8}
Now calculate the corresponding values of y.
x=-4
[tex]\displaystyle y=\frac{5}{4}(-4)-2=-5-2=-7[/tex]
y=-7
x=0
[tex]\displaystyle y=\frac{5}{4}(0)-2=0-2=-2[/tex]
y=-2
x=4
[tex]\displaystyle y=\frac{5}{4}(4)-2=5-2=3[/tex]
y=3
x=8
[tex]\displaystyle y=\frac{5}{4}(8)-2=10-2=6[/tex]
y=8

In Exercises 1-3, graph AABC and its image after a reflection in the given line.
1. A(0, 2), B(1, -3), C(2, 4); x-axis
1.
2. A(-2,-4), B(6,2), C(3. – 5); y-axis
3. A(4, -1), B(3, 8), C(-1, 1); y = -2
Answer:
1. Point A: (0, 2)
Point B: (-1, -3)
Point C: (-2, 4)
2. Point A: (-2, 4)
Point B: (6, -2)
Point C: (3, 5)
3. Point A: (4, -3)
Point B: (3, -12)
Point C: (-1, -5)
Step-by-step explanation:
1.
Reflection of point A:
Reflections over the x-axis are really easy. All you have to do is change the x-coordinate to the opposite sign.
In this case, 0 does not need to change since it already lies on the x-axis.
The coordinate for A will stay the same as (0, 2).
Reflection of point B:
Again, change the x-coordinate to negative.
1 → -1
The coordinate for B will now be (-1, -3).
Reflection of point C:
2 → -2
The coordinate for C will now be (-2, -4).
2.
Reflection of point A:
Reflections over the y-axis are also really easy. This time, all you have to do is change the y-coordinate to the opposite sign.
In this case, -4 would change to just 4.
The coordinate for A will stay the same as (2, 4).
Reflection of point B:
Again, change the y-coordinate to negative.
2 → -2
The coordinate for B will now be (6, -2).
Reflection of point C:
-5 → 5
The coordinate for C will now be (-1, 5).
3.
This is going to be a bit harder than the previous two, but I know you can handle it. :)
Reflection of point A:
The x will stay the same and only the y will change.
Take the y-coordinate and subtract it from the reflection line while getting the absolute value..
|(-1) - (-2)| = |1| = 1
This means, point A is one unit down the line y = -2
(-2) - 1 = -3
The coordinate for A will now be (4, -3).
Reflection of point B:
Again, the x will stay the same and only the y will change.
Using the absolute value, get the y-coordinate and subtract it from the reflection line again..
|(8) - (-2)| = |10| = 10
This means, point A is five unit down the line y = -2
(-2) - 10 = -17
The coordinate for B will now be (3, -12).
Reflection of point C:
I think you get the gist of it.
|(1) - (-2)| = |3| = 3
(-2) - 3 = -5
The coordinate for C will now be (-1, -5).
The red triangle is the original image and the blue triangle is the image after the reflection. The purple line is the reflection line.
Hope this helped!
The graph of Exercises 1-3 that shows AABC and its image after a reflection in the given line can be done using the example from the graph attached.
What is reflection about?A reflection over line is known to be a kind of transformation where each point of the main or original figure (that is the pre-image) is said to be made up of an image that has similar distance from the reflection line.
Note that In a reflection, the image is said to be of similar size and also of the same shape as the original image.
Therefore to be able to construct the graph of Exercises 1-3, one can use the image example by tracing the number values such as A(0, 2), B(1, -3), C(2, 4); x-axis, A(-2,-4), B(6,2), C(3. – 5); y-axis and A(4, -1), B(3, 8), C(-1, 1); y = -2 on the graph and linking them up together to form an angle.

Instead of dividing both sides by 5, it is multiplied
5x + 3 = 6 {Subtract 3 from both sides}
