Answer:
1) y = -3x + 9
2) y = -3/4x + 6
3) y = x - 5
Step-by-step explanation:
1) 3x + y - 7 = 2
+7 +7
3x + y = 9
-3x -3x
y = -3x + 9
2) 3x + 4y = 24
-3x -3x
4y = -3x + 24
4 4 4
y = -3/4x + 6
3) x - y = 5
-x -x
-y = -x + 5
-1 -1 -1
y = x - 5

A. 50.0%
59.1%
49.3%
D. 40.9%
o
Answer:
49.3%
Step-by-step explanation:
37 / 75 = 49.3%
The answer is 49.3%.
Probability is the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.
How to find that at least 7 will be girls?
Given that 75 babies are born assume that boys and girls are equally probable.
Then the probability that at least 37 will be girls is
37 / 75 = 49.3%.

What is the equation of the graph below?
On a coordinate plane, a curve goes through (0, 0). It has a maximum of 1 and a minimum of negative 1. It goes through one cycle at StartFraction 2 pi Over 3 EndFraction
y = sine (StartFraction x Over 3 EndFraction)
y = sin(3x)
y = sin(0.3x)
y = sine (StartFraction 2 x Over 3 EndFraction)
Answer:
B
Step-by-step explanation:
just took the test on edge
By using the given information, the period particularly, we conclude that the function is y = sin(3x).
What equation describes the given graph?
First, we know that:
The function goes through (0, 0).The maximum is 1The minimum is -1With these 3 considerations, we know that the function is something like:
y = sin(k*x)
So we only need to find the value of k.
We also know that the period of the function is: (2/3)*pi
This means that:
sin(k*(x + (2/3)*pi) = sin(k*x)
Remember that the period of the sine function is 2pi, then:
k*(2/3)*pi = 2pi
k/3 = 1
k = 3
Then the function is:
y = sin(3x).

Help please !!! Meg correctly solves 4680 divided by 40. Enter numbers in the boxes to show the equations she could use to solve the problem.
(4000 divide )+ (600 divide
+ (80 divide)
What is 4680 divided by 40
Enter the answer in the box.
Answer:
117
Step-by-step explanation:
Here, we have to find the result when 4680 is divided by 40.
Meg wants to simplify the process of division here.
We know that 4680 can be written as 4000 + 600 + 80.
So,
[tex]4680 \div 40 = (4000 \div 40) + (600\div 40) + (80\div 40)\\\\\Rightarrow 100 + 15 + 2\\\Rightarrow 117[/tex]
This method makes division very easy if we have to find results of division for large numbers. This example is an illustration of the same.
Please refer to image attached for results.
Hence, Meg gets the result as 117.

Find the volume of this figure
Answer:
74
Step-by-step explanation:
you find the volume of each one by doing length * width * height and once you find the volume of all of them which is 36, 2, 36 you add them all together and you get 74
Answer:
74 ft
Step-by-step explanation:
Volume = length x width x height
For the 1st square - 3 x 3 x 4
For the rectangle in the middle - 1 x 1 x 2
For the last big square - 3 x 3 x 4

Erin made a line plot of the amount of time she practiced shooting free throws each day in the past 10 days.
Line plot named as ALTDCTime Spent Practicing (hours)ALTDC shows a number line from one-fourth to two and one-fourth. The number line is divided into 8 equal parts. 1 dot on one-half, 2 dots on three-fourths, 3 dots on 1, 2 dots on one and one-fourths, 1 dot on one and half and 1 dot on 2 is given.
Part A
What is the difference between the greatest and least times Erin practiced shooting free throws?
A. 1 hour
B. 114hours
C. 112hours
D. 2 hours
Part B
What is the most common amount of time Erin practiced shooting free throws?
Enter your answer in the box.
hour(s)
Part C
Drag the numbers to write an equation for the total amount of time t Erin practiced shooting free throws in the 10 days.
Numbers may be used once, more than once, or not at all.
Part D
What is the total amount of time Erin practiced shooting free throws in the 10 days?
A. 11 hours B. 1112 hours C. 1134 hours D. 12 hours
Answer:
Data: for the 10 days of practice, we have:
0.5 hours 1 time.
0.75 hours 2 times
1 hour 3 times
1.25 hours 2 times
1.5 hours 1 time
2 hours 1 time.
A) the largest amount number of times that she practiced by the same amount of time is 3 (for the 1-hour practice)
The smallest is 1 ( for the 0.5h, 1.5h, and 2h practices)
the difference is 3 - 1 = 2.
B) the time that she practiced more times is 1 hour, she practiced that amount of time in 3 different days out of the 10 days.
C) the equation can be found by multiplying the number of hours by the number of times that she practiced that amount of time, and then adding all of them:
0.5h*1 + 0.75h*2 + 1h*3 + 1.25h*2 + 1.5h*1 + 2h*1
D) the solution for the previous equation is 11 hours. Here the correct option is A.
The sum of two rational numbers is 2. If one of them is -13/5, find the other

The number of tiles he will need 42.
What is the area of a parallelogram?The area of a parallelogram is the product of the base and the height of the figure.
The area of a parallelogram = Base x Height
We are given that top of the table measures 18 inches by 14 inches. If each tile has four sides of length 3 inches with a height of 2 inches.
Area of table = Base x Height
= 18 x 14
= 252
Area of glass parallelogram tiles = Length x width
= 3 x 2
= 6
Now,
252 = 6 x number of tiles
number of tiles = 252 / 6
= 42
