Answer: the solution to the system of equations is approximately (3.5, 2.25)
Step-by-step explanation:
The first equation can be rewritten in the form y = mx + b, where m is the slope and b is the y-intercept, by solving for y:
-3x + 2y = -6
2y = 3x + 6
y = (3/2)x + 3
The second equation already has the form y = mx + b:
y = -1/2 x + 4
Now that both equations are in the form y = mx + b, we can graph them on a coordinate plane and find the point at which they intersect, which is the solution to the system. The x and y coordinates of the intersection point are the values that satisfy both equations simultaneously.
The x and y values of the intersection point can be found either by solving for x and y or by using the method of substitution.
By using substitution, we can substitute the value of y from the second equation into the first equation to solve for x:
-3x + 2(-1/2 x + 4) = -6
-3x + (-x + 8) = -6
-4x + 8 = -6
-4x = -14
x = 3.5
Now that we have found x, we can substitute it into either equation to find y:
y = -1/2 x + 4
y = -1/2 * 3.5 + 4
y = 2.25
So, the solution to the system of equations is approximately (3.5, 2.25).

Answer:a+8
Step-by-step explanation:
I think it’s a+8 because since the difference between the 2 numbers is 8 to get the other number you have to add 8 to a.
Answer: hope this helps ♡
a + 8 = x
Step-by-step explanation:
The lesser number = a
The greater number = x
The difference = 8
Expression:
a + 8 = x
(Eg: a=4 x=12 difference=8 expression=4+8=12)
Which expression is equivalent to -6?
-8 + (-2)
-8 - (-2)
-2 + (-8)
2 - (-8)
Answer:
It would be -8 - (-2)
Step-by-step explanation:
It would be the second choice because it's the only one with a negative six.
Answer:
-8 - (-2) is equivalent to -6.
Step-by-step explanation:
-8 + (-2) = -8 - 2 = -10
-8 - (-2) = -8 + 2 = -6 ✓
-2 + (-8) = -2 - 8 = -10
2 - (-8) = 2 + 8 = 10

70 faculty members at a school 14 of the faculty members are male. what percentage of the faculty is female? please show your work.
Answer: 80% of the faculty is female
Step-by-step explanation:
To find the percentage of the faculty that is female, we need to first determine how many faculty members are female.
Number of female faculty members = Total faculty members - Number of male faculty members
Number of female faculty members = 70 - 14
Number of female faculty members = 56
Now we can calculate the percentage of the faculty that is female by dividing the number of female faculty members by the total faculty members and multiplying by 100.
Percentage of female faculty members = (Number of female faculty members / Total faculty members) x 100
Percentage of female faculty members = (56 / 70) x 100
Percentage of female faculty members = 0.8 x 100
Percentage of female faculty members = 80%
Therefore, 80% of the faculty at this school is female.

Question 1
The double box-and-whisker plot shows the goals scored per game by two hockey teams during a 20-game season.
Team A: median = 3, IQR = 2
Team B: median = 7, IQR = 2
The variation in the goals scored is the same, but Team B usually scores about 4 more goals per game.
Express the difference in the measures of center as a multiple of the measure of variation.
Answer:
To express the difference in the measures of center as a multiple of the measure of variation, we can use the coefficient of variation (CV), which is a measure of relative variability. The CV is calculated by dividing the standard deviation by the mean and expressing the result as a percentage.
However, in this case, we are not given the standard deviation or the mean of the data. Instead, we are given the median and the interquartile range (IQR) for each team. The IQR is a measure of the spread of the middle 50% of the data and is calculated by subtracting the first quartile (Q1) from the third quartile (Q3).
To find the measure of variation, we can use the IQR for each team. The IQR for Team A is 2, and the IQR for Team B is also 2.
To find the difference in the measures of center, we can subtract the median of Team A from the median of Team B:
7 - 3 = 4
Therefore, the difference in the measures of center is 4.
To express this difference as a multiple of the measure of variation, we can divide the difference by the IQR for either team. Let's use the IQR for Team A:
4 / 2 = 2
Therefore, the difference in the measures of center is 2 times the measure of variation (IQR) for Team A.

Fill in the blank 1: -23
Fill in the blank 2: -33
Fill in the blank 3: 23
Fill in the blank 4: 10
Step-by-step explanation:
The first fill in the blank is solved by adding -23 or subtracting 23 from -13 to equal the other side of the equation. The second fill in the blank is solved by adding -23 and -13, which would get you -33 (assuming that you're supposed to solve the right side of the equation). The 3rd fill in the blank is solved by adding the opposite of -23 to the right side of the equation (23). The 4th fill in the blank is solved by adding -13 and 23 together which make 10.
Answer:
1. -23
2. -33
3. 23

Answer:
Let the tree be x, the puppies be y, and the flowers be z.
Given: x + 26 = 114
When finding x: x = 114 - 26
x = 88, Therefore the tree has a value of 88.
Given: y + y + y = 159
When finding y: 3y = 159
y = 159/3 = 53, Therefore the puppies have a value of 53 each.
Given: z - 26 = 200
When finding z: z = 200 + 26
z = 226, Therefore the flowers have a value of 226.
