Drag and drop numbers into the equation to complete the equation of the line in slope-intercept form.The line passes through (8, 19) and (5, 1).
Answers
we are given two points
(8,19) and (5,1)
firstly, we need to calculate the slope
slope = y2 - y1 / x2 - x1
from the points
x1 = 8, y1 = 19, x2 = 5, y2 = 1
slope = 1 -19 / 5 - 8
slope = -18/-3
negative will cancel each other
slope = 18/3
slope = 6
slope intercept equation is
y - y1 = m(x - x1)
m = slope = 6
y1 = 19 and x1 = 8
y - 19 = 6(x - 8)
open the parentheses
y - 19 = 6*x - 6*8
y - 19 = 6x - 48
make y the subject of the formula
y = 6x - 48 + 19
y = 6x - 29

If each book weighs the same amount, how much does each book weigh? Show your work
Answers
Hello there. To solve this question, we'll have to remember some properties about mixed fractions.
5 book weight a total of 6 2/5 pounds. If each book weighs the same amount, how much does each book weigh?
We start by converting the fraction from the mixed fraction notation to the normal notation:
Therefore we have:
Now, suppose each book weigh x pounds. 5 books weight will be equal to 5x.
If 5 books weigh 32/5, then we have the following equation:
Divide both sides of the equation by a factor of 5
To find the value of this fraction, the trick is to multiply it by 4/4 (when the denominator is 25):
Each book weighs 1.28 pounds.
Problem: Solve the following equations for the given variable: 1. P = 2L + 2W for W. 2. 2x + 3y = -10 for y.
Answers
EXPLANATION
Given the equations:
1. P = 2L + 2W for W. (Subtracting 2L to both sides)
P - 2L = 2l + 2W - 2l (Dividing both sides by 2)
P/2 -2L/2 = W (Simplifying and switching)
W = P/2 - L
2. 2x + 3y = -10 for y. (Subtracting 2x to both sides)
2x - 2x + 3y = -10 -2x (Simplifying)
3y = -2x - 10 (Dividing both sides by 3)
y = -2x/3 - 10/3

Lynn is tracking the progress of her plant's growth. The plant is already 8 centimeters high. The plant grows 1.5 centimeters per day. Which function shows this relationship? y=8x+1.5y=1.5x+8y=9.5x
Answers
Given the information, we know that the plant is already 8 centimeters, therefore that would be our intercept with the y-axis (i.e. b = 8). Now, to find the slope, we have that on the first day the plant grows 1.5 centimeters, therefore for day 1, the plant is 9.5 centimeters high. With this observations we have the following:
[tex]\begin{gathered} \text{Given (0,8) and (1,9.5)} \\ m=\frac{y_2-y_1}{x_2-x_1} \\ \Rightarrow m=\frac{9.5-8}{1-0}=1.5 \\ m=1.5 \end{gathered}[/tex]Using the formula y=mx+b, we obtain the desired function:
[tex]\begin{gathered} y=mx+b \\ \Rightarrow y=1.5x+8 \end{gathered}[/tex]Therefore, the function that shows the relationship is y=1.5x+8

EXPLANATION
Since we have the system of equations:
(1) 2x - 4y = 20
(2) x = 4
Plugging in x=4 into (1):
2*4 - 4y = 20
Multiplying numbers:
8 - 4y = 20
Subtracting -8 to both sides:
-4y = 20 -8
Subtracting numbers:
-4y = 12
Dividing both sides by -4:
y = 12 / -4
Simplifying:
y = -3
The solution to the system of equations is (x,y) = (4,-3)

A basket of fruits contains 50 mangoes and 30 orange. what percentage of the fruits are oranges?
Answers
The percentage of oranges is the basket of fruits is 37.5%.
According to the question,
We have the following information:
A basket of fruits contains 50 mangoes and 30 orange.
Now, we can easily find the number of oranges in this basket by following the given steps.
Total number of fruits in the basket = number of mangoes + number of oranges
Total number of fruits = 50+30
Total number of fruits = 80
Percentage of oranges in the basket = Number of oranges in the basket*100/total number of fruits in the basket
Percentage = (30*100)/80
Percentage = 37.5%
Hence, the percentage of oranges is the basket of fruits is 37.5%.

First of all we are going to find the slope perpendicular to the equation y = -1/2 x +6.
We need to remember that two slopes are perpendicular if its product is equal to -1. Like this:
[tex]\begin{gathered} m_1\cdot m_2=-1 \\ m_1=-\frac{1}{2}_{} \\ m_2=-\frac{1}{m_1}=-\frac{1}{-\frac{1}{2}}=2 \\ m_2=2 \end{gathered}[/tex]Now, we find the equation of the line using the general form:

Under her cell phone plan, Ella pays a flat cost of $58.50 per month and $3 per gigabyte, or part of a gigabyte. (For example, if she used 2.3 gigabytes, she would have to pay for 3 whole gigabytes.) She wants to keep her bill under $65 per month. What is the maximum whole number of gigabytes of data she can use while staying within her budget?
Answers
The maximum number of gigabytes of data she can use while staying within her budget is 2 gigabytes.
Given that Ella pays a flat cost of $58.50, and per gigabyte used have to pay $3. If she uses g gigabytes she has to pay $3xg.
Now we have to find the maximum whole number of gigabytes data, she can use within her budget.
Her budget is less than $65.
We can create a inequality expression for this, as follows.
58.50+3g< 65
Calculating further, we get
3g<65-58.50
3g<6.5
g<6.5/3
g<2.163.
Therefore, the maximum whole of gigabytes, she should use to keep the expense within budget is 2 gigabytes.

Explanation:
In the function, the first set represents the x and the second set represents f(x), so to find for which values of x does f(x) = 4, we need to identify the beginning of the arrows that end in the number 4.
Therefore, these numbers are 3 and 5. It means that x = 3 and x = 5 make f(x) equal to 4.
So, the answers are x = 3 and x = 5.
What is the perimeter of triangle XYZ? A. 17.1 cmB. 15.1 cmC. 13.1 cmD. 11.1 cm
Answers
The perimeter of the triangle XYZ is 15.1 cm.
The two given triangles are ΔUVW and ΔXYZ are similar.
In ΔUVW ∠U=36°
In ΔXYZ ∠Y = 72° and ∠Z = 72° , ∴ ∠X = 180° - (72+72)° = 36°
Hence in the two triangles we can assume that they are similar by AAA axiom of similarity
So the sides of the triangle XYZ will be
XY = 5.7 cm
YZ = 5.7 cm
ZX = 3.7 cm
Hence the perimeter = XY+YZ+ZX = 5.7 + 5. 7+ 3.7 = 15.1 cm
