PLEASSSEEE HELP I’VE BEEN STUCK ON THIS FOR A COUPLE OF DAYS .. 15 points
Answers
Answer:
The equations of the line are
y + 7 = [tex]\frac{9}{7}[/tex] (x + 4) ⇒ B
y - 2 = [tex]\frac{9}{7}[/tex] (x - 3) ⇒ E
Step-by-step explanation:
The point-slope form of the linear equation is
[tex]y-y1=m(x-x1)[/tex] , where
m is the slope of the line(x1, y1) is a point on the lineThe rule of the slope is [tex]m=\frac{y2-y1}{x2-x1}[/tex]∵ The line passes through points (-4, -7) and (3, 2)
∴ x1 = -4 and y1 = -7
∴ x2 = 3 and y2 = 2
→ Use the rule of the slope above to find it
∵ [tex]m=\frac{2--7}{3--4}=\frac{2+7}{3+4}=\frac{9}{7}[/tex]
∴ The slope of the line is [tex]\frac{9}{7}[/tex]
→ Substitute the values of m and (x1, y1) in the form of the equation above
∵ y - -7 = [tex]\frac{9}{7}[/tex] (x - -4)
∴ y + 7 = [tex]\frac{9}{7}[/tex] (x + 4)
∴ The equation of the line is y + 7 = [tex]\frac{9}{7}[/tex] (x + 4)
→ Substitute the values of m and (x2, y2) in the form of the equation above
∵ y - 2 = [tex]\frac{9}{7}[/tex] (x - 3)
∴ The equation of the line is y - 2 = [tex]\frac{9}{7}[/tex] (x - 3)
→ Look at the answers to find the same equations
∴ Answers B and E have the same equations

Answers
Answer:
A: 1/3
Step-by-step explanation:
The ratio is 1 part water to 3 parts juice.
The amount of water in the ratio works out to be 1/3 of the amount of juice.
For 1 part juice, use 1/3 of that amount of water, so use 1/3 part water.

THIS IS STATISTICS** Are physically fit people less likely to die of cancer? An article in the May 2002 issue of "Medicine and Science in Sports and Exercise" reported results of a study that followed 25,892 men aged 30 to 87 for 10 years. The most physically fit men had a 55% lower risk of death from cancer than the least fit group. What is the population of interest and the sample in this scenario? Write your response using complete sentences. plz help
Answers
Answer:
In this case the population of interest is the set of all men aged 30 to 87.
In this case the sample is the set of 25,892 men aged 30 to 87.
Step-by-step explanation:
A population is the set of all the data that can be collected and from which a smaller set of data is drawn for further examination. A population may denote to a group of individuals, articles, trials or measurements. A population can thus be called as a collection of information regarding subjects combined together by a common characteristic.
In this case the population of interest is the set of all men aged 30 to 87.
A sample denotes a smaller, controllable form of a larger cluster. It is a subset comprising of the characteristics of a bigger population. Samples are used in statistical experiments when the population under consideration is too large for the test to include all the members.
In this case the sample is the set of 25,892 men aged 30 to 87.

How would you solve this(what is the equation of the line that passes through the point (3,4) and has a slope of -2/3?)//delta math//
Answers
Answer:
[tex]y = -\frac{2}{3}x + 6[/tex]
Step-by-step explanation:
y = mx + b is the formula for slope intercept. What we can do is plug in the slope and coordinate points to find the y-intercept.
4 = [tex]-\frac{2}{3}[/tex](3) + b
-2/3 times 3 is -2 so you can fill that in place.
4 = -2 + b
+2 +2
6 = b
So the y-intercept is 6 now we can complete the equation.
[tex]y = -\frac{2}{3}x + 6[/tex]
Hope that helps and have a great day!

Mr. Shaw graphs the function f(x) = -5x + 2 for his class. The line contains the point (-2, 12). What is the point-slope
form of the equation of the line he graphed?
Oy - 12 = -5(x + 2)
Oy - 12 = 2(x + 2)
O y + 12 = 2(x - 2)
O y + 12 = -5(x - 2)
Answers
Answer:
The first choice is correct. y-12=-5(x+2)
Step-by-step explanation:
Point-Slope Form of a Line
The point-slope form of the equation of a line is:
y-k=m(x-h)
Where m is the slope and (h,k) is a point through which the line passes.
The equation of the line in slope-intercept form is:
y=mx+b
Where b is the y-intercept.
Mr. Shaw graphs the function y=f(x)=-5x+2
The coefficient of the x can be identified as the slope m=-5. We are given the point (-2,12) to build the point-slope form of Mr. Shaw's line as follows:
y-12=-5(x+2)
The first choice is correct. y-12=-5(x+2)

What’s a better buy? 80 marbles for $4.99 or 90 marbles for $5.99?
Answers
80 marbles for $4.99 is a better buy as compared with 90 marbles for $5.99
What is comparison in mathematics?
Comparing numbers in math is defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.
Given are 80 marbles for $4.99 and 90 marbles for $5.99.
Using Unitary method -
80 marbles cost → $4.99
1 marble will cost → (4.99/80) = $0.062
90 marbles cost → $5.99
1 marble will cost → (5.99/90) = $0.066
Clearly $0.062 < $0.066
So, 80 marbles for $4.99 is a better buy.
Therefore, 80 marbles for $4.99 is a better buy as compared with 90 marbles for $5.99
