Find the slope of the line through the given pair of points, if possible. Based on the slope, indicate whether the line through the points rises from left to right, falls from left to right, is horizontal, or is vertical. (3.-5) and (2-2)
А. -3, falls
В. 1/3, rises
C. 3, rises.
D. -1/3, falls
Answers
Answer:
Slope of line having points (3,-5) and (2,-2) is 3 and since the slope is positive do it rises. Option C is correct option.
Step-by-step explanation:
The formula calculate to find slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given points (3,-5) and (2,-2) so,
[tex]x_1=3, y_1=-5, x_2=2, y_2=-2[/tex]
Putting values in formula and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-2-(-5)}{2-3}\\Slope=\frac{-2+5}{1}\\Slope=3[/tex]
So, Slope of line having points (3,-5) and (2,-2) is 3 and since the slope is positive do it rises. Option C is correct option.
Translate the following sentence into a mathematical equation. The sum of 10 and five times a number is the same as the difference of the number and 6
Answers
Answer:
The sentence in mathematical form is: [tex]5x+10 = x-6[/tex]
Step-by-step explanation:
The given statement can be converted into a mathematical equation step by step.
First of all, we have to suppose a variable for the number as we don't know the exact number.
So,
Let x be the number then
five times a number => 5x
The sum of 10 and five times a number => 5x+10
the difference of the number and 6 => x-6
Putting in equation form we get
[tex]5x+10 = x-6[/tex]
Hence,
The sentence in mathematical form is: [tex]5x+10 = x-6[/tex]

The Answer will be -8 using fraction operation.
What is a fraction?If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.
Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.
First solve the 2nd part which is
[tex]\frac{-2}{3}*-4\frac{1}{2} \\=3[/tex]
Now -8/3 * 3 = -8
Hence the answer for the given question will be -8.

If using the method of completing the square to solve the quadratic equation x^2-19x+9=0 which number would have to be added to "complete the square"?
Answers
Answer:
90.25Step-by-step explanation:
Given the quadratic equation x^2-19x+9=0 re arranging we have;
x^2-19x+9 - 9=0 -9
x^2-19x = - 9
In order to complete the square we would add a number to both sides and the number will be the square of the half of coefficient of x in the expression as shown.
Coefficient of x = -19
half of coefficient of x = -19/2
square of the half of coefficient of x = (-19/2)²
square of the half of coefficient of x = 361/4
square of the half of coefficient of x = 90.25
Hence the number that would have to be added to "complete the square" is 90.25
x + 4 < 6

1. Judy took $15 with her to spend on popcorn and drinks for herself and her friends at the movie theater. The price for each bag of popcorn was $3. The price of each drink was half the price of a bag of popcorn.
(a) Sketch the graph that represents the situation and label the intercepts. Use one axis to represent the number of bags of popcorn and the other axis to represent the number of drinks.
Answers
Answer:
Let the number of popcorn be x and the number of drinks be y, then according to the question we have the following equation
.................> linear equation
To sketch the graph first we need to find two points on it.
EXAMPLE
put x=0, we get y=10
put y=0, we get x=6
Thus, we have points (0,10) and (6,0), now sketch a line through it .

Step-by-step explanation:
5 units up means add 5 to the y- coordinate
3 units left means subtract 3 from the x- coordinate
Translation rule is
(x, y ) → (x - 3, y + 5 ) , thus
(3, 5 ) → (3 - 3, 5 + 5 ) → (0, 10 )
a rectangle has a length of x3y4 inches a width of xy7 inches. which expression represents the ratio of the length of the rectangle to the width of the rectangle?
Answers
Answer: R = x^2/y^3
Step-by-step explanation:
here we will use the relation:
x^a/x^b = x^(a - b)
We know that:
Length = x^3*y^4
Width = x*y^7
And we want to find an expression that represents the ratio between the length and the width.
Then we just need to take the quotient Lenght/width or:
R = ( x^3*y^4)/(x*y^7)
Now first let's distribute in such way the x's and the y's are separated, and then let's use the relationship that is above.
= (x^3/x)*(y^4/y^7) = x^(3 - 1)*y^(4 - 7) = x^2*y^-3
R = x^2/y^3
The ratio of the length of the rectangle to the width of the rectangle is [tex]\frac{x^{2} }{y^{3} }[/tex]
Rectangle:Given that,
Area of rectangle is multiplication of length and width of rectangle.
length of rectangle [tex]=x^{3} y^{4}[/tex] inches
Width of rectangle [tex]=xy^{7}[/tex] inches.
the ratio of the length of the rectangle to the width of the rectangle is,
[tex]=\frac{x^{3}y^{4} }{xy^{7} } =\frac{x^{2} }{y^{3} }[/tex]

What is metric conversion?Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
The question states that 1 inch = 4 miles. Therefore, if you multiply 31412 inches by 4, you will get the total number of miles you will be traveling for the round trip.
31412 × 4 = 125650
Therefore, the total number of miles you will be traveling for the entire round trip is 125650 miles.
