Which expression makes the equation true for all values of x?
16x - 16 = 4( ? )
A 4x - 4
B 4x - 16
C 2x - 2
D 12x - 12
Answer:
A since if we multiply 4 × 4x, we get 16x, and 4 × 4, we get 16, which cancels with the other 16x - 16 on the left side. That makes sure that any x we choose will cancel out in the end.
Step-by-step explanation:
1. 16x - 16 = 4(4x-4)
2. 16x - 16 = 16x - 16
3. 0 = 0
2t - 3 = 1 (solve for t)
we're doing two step equations
Answer: t = 2
Step-by-step explanation:
2t - 3 = 1
(add 3 to both sides)
2t = 1 + 3
2t = 4
(divide 2 from both sides)
t = 2

Answer:
Hello! answer: 452.16
Step-by-step explanation:
Im using 3.14 for pi
the radius is just half of the diameter so...
72 × 2 = 144 144 × 3.14 = 452.16 therefore the distance around the Ferris wheel is 452.16 Hope this helps.

Choice B) As x decreases, y decreasesChoice C) As x increases, y approaches 0Choice F) The function is an increasing function=====================================================
Explanation:
The graph has a negative y-intercept. So for example, we could have a y intercept of (0,-1) or (0,-2). The x value is always 0, and in this case, the y coordinate is some negative number.
Due to the negative y intercept, this means the function curve is below the x axis at this point. The common ratio r, such that 0 < r < 1, tells us that the exponential function is decreasing in absolute value. Let's say the y intercept was (0,-10) and the common ratio was r = 0.5
The common ratio of r = 0.5 means the second term is r*(first term) = 0.5*(-10) = -5, and the third term is r*(second term) = 0.5*(-5) = -2.5
The terms: -10, -5, -2.5 show us that they are decreasing in absolute value, but in terms of a graph, they are going upward toward zero.
So that's why as x increases, so does y (which makes it an increasing function). And y is approaching y = 0. However, it never actually gets to y = 0.
On the flip side, if x is decreasing, then y is also decreasing. Both x and y increase or decrease together in any increasing function. A decreasing function would have x increase while y decreases, or vice versa, meaning they go in opposite directions.

You work on a problem calculating either area or volume. Your answer is 210 ft3. Did you work on an area or volume problem?
Answer:
A volume problem.
Step-by-step explanation:
An area problem would be 210 ft2 because you multiply two numbers but with volume you multiply three.

NO VIRUS LINKS!!! Since opening night, attendance at Play A has increased steadily, while attendance at Play B first rose and then fell. Equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. On what day(s) was the attendance the same at both plays? What was the attendance?
Play A, y= 9x+64
Play B, y= -x^2+26x+12
Answer:
I pretty sure the answer is A
Step-by-step explanation:
1.Since opening night, attendance at Play A has increased steadily, while attendance at Play B first rose and then fell. Equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. On what day(s) was the attendance the same at both plays? what was the attendance?
Play A: y=7x+84
Play B: y=-x^2+40x-6
A. The attendance was the same on day 30. The attendance was 294 at both place that day.
B.The attendance was the same on day 3. The attendance was 105 at both place that day.
C. The attendance was never the same at both plays
D. The attendance was the same on days 3 and 30. The attendance at both plays on those days was 105 and 294 respectively.
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.
Part A
Whose scatter plot matches the data, and what is wrong with the incorrect scatter plot?
Part B
Using the correct graph, describe the association shown
Part C
What is the slope of the line in the correct graph? What is the slope of the line in the incorrect graph? Are the slopes the same or different?
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?
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

Solve for X
x + 4.6 = 12.96
Answer:
x = 8.36
Step-by-step explanation:
First, subtract 4.6 from both sides of the equation, then just simplify.
Answer: x = 8.36
(same thing as 209/25)
Step-by-step explanation:
Move the constant to the right hand side and change its sign.
x = 12.96 - 4.6
Subtract the numbers.
x = 8.36

On a certain hot summer's day,432 people used the public swimming pool. The daily prices are $1.50 for children and $2.00 for adults. The receipts for admission totaled 664.50How many children and how many adults swam at the public pool that day?
Answer:
399 children, 33 adults
Step-by-step explanation:
Children = c
Adults = a
c + a = 432
a = 432 - c
1.5c + 2a = 664.50
1.5c + 864 - 2c = 664.50
-.5c + 864 = 664.50
-.5c = -199.5
.5c = 199.5
c = 399
432 - 399 = 33
a = 33
Answer:
kids = 399
adults = 33
