The estimates for [tex]6\frac{1}{9}. 1\frac{5}{7}[/tex] is [tex]10\frac{10}{21}[/tex]
The actual answer of [tex]6\frac{1}{9}. 1\frac{5}{7}[/tex] is [tex]10\frac{30}{63}[/tex]
How to estimate fractions?The estimated answer of the fraction can be done as follows:
[tex]6\frac{1}{9}. 1\frac{5}{7}[/tex]
Hence,
[tex]6\frac{1}{9} = \frac{55}{9}[/tex]
[tex]1\frac{5}{7} = \frac{12}{7}[/tex]
Therefore, the actual answer of the fractions is as follows:
[tex]\frac{55}{9}.\frac{12}{7} = \frac{660}{63} = 10\frac{30}{63}[/tex]
Hence, the estimated answer of the fractions can be calculated as follows
[tex]\frac{55}{9}.\frac{12}{7} = \frac{660}{63} = \frac{220}{21} = 10\frac{10}{21}[/tex]

What is inequalities ?Equations are not necessarily about having a "equal to" sign balanced evenly on both sides. It can occasionally refer to a "not equal to" connection, where one object is more than the other or less than. A connection that compares two numbers or other mathematical expressions in an unequal way is referred to as an inequality in mathematics. These mathematical statements are classified as inequalities in the algebraic language.
To test point in that system satisfies both of the inequalities
The system of inequalities is shown by the graph.

Mr. Vigrass was driving at a constant speed he drove 168 miles in 3 1/2 hours at that speed how many miles will he drive in one hour
Answers
Using speed, distance and time relation, Mr. Vigrass will travel 48 miles in an hours.
What is the relation between speed, distance and time?If we know how far something travels and how long it takes, we can determine how fast something is moving in a straight line. This equation illustrates the link between journey time, distance, and speed:
Distance divided by travel time equals speed.
Distance equals Time * Speed
Time = Speed / Distance
Distance x Time equals Speed
Given,
distance = 168 miles
time = 3 1/2 hours
speed = distance / time
speed = 168 × 2/7
speed = 48 miles/hour
At same speed,
distance travelled in 1 hour will be
distance = speed × time
distance = 48 × 1
distance = 48 miles.

F(x)=|x|-7 describe the transformation of each function compared to its parent function
Answers
Compared to the parent function f(x)=|x|, the graph of F(x) is a translation 7 units down.
First, the negative on the top of the fraction indicates that there is a reflection. This means that you will be filling in quadrants II and IV rather than I and III prior to the other transformations.
Dilation is indicated by the 3 in the numerator of the fraction and will actually affect the main points marked on the graph. For the parent function y= 1/x, the coordinate (1,1) is the main point in the first quadrant and the coordinate (-1,-1) is the main point in the third quadrant. When a dilation occurs, it dilates the x value for one of the coordinates and the y-value in the other. Since a reflection has also occurred, our initial points are (-1,1) and (1,-1) so the points in the second quadrant will be (-1,3) and (-3,1) as compared to the asymptotes (multiple translations have also occurred) and the points in the fourth quadrant will be (1,-3) and (3,-1) as compared to the asymptotes.
Lastly, let's consider translations: a horizontal translation involves the addition or subtraction of a number from x in the denominator of the fraction whereas a vertical translation involves the addition or subtraction of a number from (1/x), completely separate from the fraction. Therefore, the -2 is part of a horizontal translation and the +4 is part of a vertical translation. I always tell my students that the direction of the vertical translation(up or down) will be what you would assume, but the direction of the horizontal translation (right or left) will be the exact opposite of your assumption. For this reason, the -2 would indicate a shift to the right 2 units and the +4 would indicate a shift upwards 4 units. This would result in a shift of the vertical asymptote to the right 2 units and a shift in the horizontal asymptote upwards 4 units. The horizontal asymptote is written as y = 4 and the vertical is written as x=2

Answer:
13
Step-by-step explanation:
We use the distance formula to find the distance between two points
d = sqrt ( (x2-x1)^2 + y2-y1) ^2)
Where ( x1,y1) and ( x2,y2) are the two points
d = sqrt( ( -1 - -6) ^2 + ( -4 - 8) ^2)
= sqrt ( ( -1+6) ^2 + ( -12) ^2)
= sqrt( 5^2 + 144)
= sqrt ( 25+ 144)
= sqrt ( 169)

Number of packages of onion soup mix required be y1 = 3
Used products by Harlan,
Cups used by Harlan of sour cream be x2 = 2
Packages of onion soup mix used by Harlan be y2 = 1.5
As we can see that,
x1/x2 = y1/y2
