help me with this question please, explain why u choose that answer and show ur steps
Answers
-1/2(-3/2 x + 6x + 1) - 3x
First we distribute the -1/2
((-1/2)(-3/2 x) + (-1/2)(6x) + (-1/2)(1)) -3x
3/4x - 3x - 1/2 -3x
Combine like terms
(3/4 x - 3x - 3x) -1/2
-21/4 x - 1/2
We could make this a mixed number
-5 1/4 x - 1/2
(Mixed number: 5 times 4 plus one gets the numerator)
So the answer is D

A zoo train ride costs $4 per adult and $1 per child. On a certain day, the total number of adults (a) and children (c) who took the ride was 27, and the total money collected was $60. What was the number of children and the number of adults who took the train ride that day, and which pair of equations can be solved to find the numbers? (1 point)
11 children and 16 adults
Equation 1: a + c = 27
Equation 2: 4a + c = 60
16 children and 11 adults
Equation 1: a + c = 27
Equation 2: 4a + c = 60
11 children and 16 adults
Equation 1: a + c = 27
Equation 2: 4a − c = 60
16 children and 11 adults
Equation 1: a + c = 27
Equation 2: 4a − c = 60

Answers
Answer:
7
Step-by-step explanation:
in 5 and 6 there are few flaws in their experiment, so there is no way to disprove the information they find. However in 7, the biologist can't prove that having 4 tagged fish out of 50 means there are 1,800 fish in that quarry. Therefore it is inaccurate and biased.

Answer:
128.74
Step-by-step explanation:
.8x = 120.00
.87x = 112.00
This represents an easier way to do the problem if there is 20% off that means you are paying 80% of the original cost. You are paying 87% if it is 13% off.
To find the price at nine-irons divide 112 by .87
20% of 120 is 24
120 - 24 = 96
96 - 8 = 88
13% of 100 is 13
100 - 13 = 87

Laura went to a golf shop that has a golf simulator. The simulator estimates the distance that each ball she hits would have gone. She hit five balls each with her 2, 3, 4, 5, 6, 7, 8, and 9 irons. The distances of her golf shots are given in the table. Keep this table window open as you work on the tasks in this activity.
When Laura graphed the data, she got this scatter plot and drew a line of best fit. Keep the scatter plot window open as you work on the tasks in this activity.
When her brother graphed the data, he got a different scatter plot and drew a line of best fit. Keep the scatter plot window open as you work on the tasks in this activity.

Whose scatter plot matches the data, and what is wrong with the incorrect scatter plot?
Part B

Part C

Part D
What is the y-intercept of the correct graph? What is the y-intercept of the incorrect graph? Are the y-intercepts the same?
Part E
If Laura were able to find a 0 iron, about how far could she hit it?
Part F
About what is the average change in distance for each increase of 1 in the iron number? What does this mean in terms of the situation?
Answers
Answer:
I can only help you with Part C and E as these two are the ones I am able to answer.
Part C: slopes are not the same
Part E: 195 yards
Step-by-step explanation:
Part C:
Part E: The slope of the line follows a linear pattern; therefore, find the equation for the line by calculating the slope and plugging in a point.
Slope:
y2-y1/x2-x1; (9, 105) (8,115)
(115-105)/(8-9) = -10; the slope is -10, now solve for the equation of the line.
y=mx+b; plug in the point (9,105)
105 = -10(9) +b
105 = -90 +b, add 90 to both sides
195 = b; rewrite the equation;
y=-10x+195; x stands for the iron, plug in 0 for x;
y=-10(0)+195
y=195 yards.
Answer:
A The scatter plot that matched the data is the second scatter plot while the first scatter plot wrongly represents the data because values of the Iron not present in the data is also represented in the scatter plot and also some values present in the data table is also missing in the First scatter plot.
B The scatter plot describes the strong negative association because in the scatter plot strong downhill linear relationship.
C In mathematics the slope or gradient of a line is a number that describes both the direction and the steepness of the line. Slope is denoted by the letter m in the equation of a straight line "y = mx + c".
D 195 yards

Answer:

Sorry i think its wrong and prabably is :( sorry
Answer:
To have infinitely many solutions they must describe the same line. So any multiple or fraction of the reference line would indeed describe the same line, and thus "intersect" at each and every of an infinite number of points.
2(x+y=4)
2x+2y=8 (is the same line as x+y=4)
