Answer:
see below
Step-by-step explanation:
It is easiest to compare the equations when they are written in the same form.
The first set can be written in slope-intercept form.
y = 2x +7
y = 2x +7 . . . . add 2x
These equations are identical, so have infinitely many solutions.
__
The second set can be written in standard form.
y +4x = -5
y +4x = -10
These equations differ only in their constant, so have no solutions.
__
The third set is already written in slope-intercept form. The equations have different slopes, so have exactly one solution.

0.3350
0.4328
0.5672
Answer: B 0.3350
Step-by-step explanation: I took the quiz
The proportion of park users jog on the park trail is 0.3350
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Given; The attached table
Required to Determine the proportion that jog on the park frail
The total number of residents (sample) is 400
From the table, those that jog are 134
The proportion (p) is then calculated as:
p = 134 / 400
p = 0.3350

Which of the following is most likely the next step in the series?
20+20+20+20+20-10-10/5
Answer:
The answer to the question is 16
Step-by-step explanation:
To find out the answer all we need to do is:-
Do addition for the first set of 20's. ( Or Multiply The 20's)
20 + 20 + 20 + 20 + 20 (or) Number of 20's = 5
= 40 + 40 + 20 The number = 20
= 80 + 20 Therefore, 20 × 5 = 100
= 100
-----------------------------------------------------------------------------------------------------------
Number of tens = 2 Therefore, 10 × 2 = 20
The number = 10
Now, we subtract 100 - 20 = 80.
-----------------------------------------------------------------------------------------------------------
We have 80 and now we divide the number by 5
If we do that we get the answer as 16.
I hope this answer helps.

Point A is at ( -3, -5) and point M is at (-0.5, 0).
Point M is the midpoint of point A and point B.
What are the coordinates of point B?
Answer:
B(1.25,5)
Step-by-step explanation:
y... -5, 0, 5
x... -0.5, 1.25, 3
Answer:
The endpoint coordinates are (2,5)
Step-by-step explanation:
You can use Omni calculator its completely free and it gives the exact answer.
The fastest way to find the missing endpoint is to determine the distance from the known endpoint to the midpoint and then performing the same transformation on the midpoint.

Answer:
They are congruent triangle
Step-by-step explanation:
They are congruent because they have the same measurements for angles and sides.
This...is confusing
Answer:
82
Step-by-step explanation:
When finding a triangle's missing angle, you first have to know that all of the angles add up to 180. Then, you add the other sides, and subtract that from 180 to get the missing angle. But in this case... Your missing two... but given one other angle. So, because a straight lines angle is 180, you would take 143 and subtract it from 180 to get the other side. There is also more steps... and sorry for not explaining further... but it would take a pretty long time...
180-143=37
A=37
37+61+_=180
37+61=98
180-98=82
The missing angle is 82 degrees
The following are a list of variables that will almost certainly vary across students in a large undergraduate introductory statistics course.
(a) Favorite beverage
(b) Year of birth
(c) Typing speed
(d) Handedness (e.g., left or right-handed)
(e) Age
(f) Occupation
(g) Self-report of Assertiveness
For questions 1a to 1d that follow choose the variable or variables that best represent the level of measurement.
a) Which variables would typically be measured on a nominal scale of measurement?
b) Which variable would likely be measured on an interval, but not a ratio scale?
c) Which two variables are most likely to be measured on a ratio scale?
d) As typically measured, which variable represents at least an ordinal scale of measurement, but probably not a true interval scale?
Answer:
a.) Favorite Beverage, Handedness, Occupation.
b.) Year of birth
c.) Age and typing speed
d.) Self-report of Assertiveness
Step-by-step explanation:
Scales of measurements are used in statistics to classify variables. The scale of measurement of a variable is important in statistics because it determines the kind of satisfaction analysis that should be used on it.
The four types of scale of measurement are;
1.) Norminal Scale: The normal scale is a categorical scale where variables are labeled with no specific order. No calculations can be done on this type of measurement because they do not have values and there is usually no order. Examples include;
Occupation, Favorite Beverage and Handedness.
2.) Ordinal Scale: This is used to show the order of variables. It is similar to the norminal scale with a slight difference. The ordinal scale has some form of ranking, that is some variables will be considered better or higher than others. Example include;
Self-report of assertiveness. Someone that claims to be highly assertive can be ranked above one that is just assertive.
3.) Interval Scale: This kind of measurements shows definite intervals between variables. It is like a scale where the order and the difference between variables are shown with no true zero value. Variables that fall under this category include; temperature and year of birth.
4.) Ratio Scale: This is the most accurate scale of measurement that encompasses the norminal, ordinal and interval scale of measurement. It has a zero value, shows order, interval and can still categorized. And example is the Age of students and typing speed.

The ordered pair that is a solution to y = -8 are:
(5, -8) and (-7, -8).
What is a solution?
Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
y = -8
We have the ordered pairs:
(5, -8), (-8, 9), (0, 6), and (-7, -8).
Now,
The solutions to y = -8.
y = -8 is a constant function.
This means,
Any value of x will give -8.
Now,
The ordered pair that is a solution to y = -8 are:
(5, -8) and (-7, -8).

Answer:
12 feet
Step-by-step explanation:
Given: length = 15 feet, width = L x 80%
Unknown: width = ?
width = L x 80%
w = (15ft) x 80% or (15ft) x .80
w = 12 ft
Answer:
Formula of rectangle :-

Actually Welcome to the Concept of the quadratic equations.
Since, as the question told,
=>
[tex] \frac{ {x}^{2} }{3} - 3 = 0[/tex]
hence now solving we get as,
[tex] \frac{ {x}^{2} }{3 } = 3 [/tex]
now, we get as,
[tex] {x}^{2} = 9[/tex]
now, then

5 Alysha has 1.46 pounds of apples, 1.5 pounds of oranges, and some peaches and plums. Part A Alysha has more pounds of peaches than pounds of apples, but fewer pounds of peaches than pounds of oranges. How many pounds of peaches could Alysha have? Show your work. pounds of peaches Answer: Part B Alysha has 1.08 pounds of plums. Which comparison is true about the weights of the fruit Alysha has?
Answer:
1.46 < p < 1.5
Step-by-step explanation:
Pounds of apple = 1.46
Pounds of oranges = 1.5
Some peaches and plum
More pounds of peaches than pounds of apple ; that is pounds of peaches > 1.46
Fewer pounds of peaches Than pounds of oranges;
Peaches < 1.5
Let pounds of peaches = p
1.46 < p < 1.5
If Alysha has 1.08 plums ;
Then ;
Plum < apple < peaches < oranges
