Answer: x = 24
Step-by-step explanation:
9x - 18 = 7x + 30
9x - 7x = 30 + 18
2x = 48
x = 48/2 = 24
Point A is at (-7,-9) and point M is at (-0.5, -3).
Point M is the midpoint of point A and point B.
What are the coordinates of point B?
Answer:
(6,3)
Step-by-step explanation:
You can solve this by looking at the x and y coordinates independently.
The distance between -7 and -0.5 is 6.5.
The distance between -9 and -3 is 6.
Since point M is the midpoint, the distances between point A and point M should be the same, so you can literally just add the distances to the midpoint to find the other endpoint. This means that point B is located at (-0.5+6.5, -3+6) or (6, 3).
To check your work you can test the slope of the line and see that it is consistent from points A to B and from A to M.
[tex]\frac{(3--9)}{(6--7)}[/tex] = [tex]\frac{12}{13}[/tex] and [tex]\frac{(-3--9)}{(-.5--7)}[/tex] = [tex]\frac{6}{6.5}[/tex] which are both equal to ≈ .923077

a person invest in 9000 in a bank. the bank pays 5% interest compounded semi annually. to the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 14800 dollars
Answer:
10.1 years.
Step-by-step explanation:
It is given that,
Principal = 9000
Rate of interest = 5%
No. of times interest compounded = 2 times in an year
Amount after certain time = 14800
The formula for amount:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
where, P is principal, r is rate of interest, n is no. of times interest compounded in an year and t is time in years.
Substitute the given values in the above formula.
[tex]14800=9000(1+\frac{0.05}{2})^{2t}[/tex]
[tex]\frac{14800}{9000}=(1+0.025)^{2t}[/tex]
[tex]1.644=(1.025)^{2t}[/tex]
Taking log both sides.
[tex]\log(1.644)=\log(1.025)^{2t}[/tex]
[tex]\log(1.644)=2t\log(1.025)[/tex] [tex][\because \log a^b=b\log a][/tex]
[tex]\frac{\log(1.644)}{2\log(1.025)}=t[/tex]
[tex]t=10.066[/tex]
[tex]t=10.1[/tex]
Therefore, the required time is 10.1 years.

The ideal mass for a piece of chocolate is 2.5 ounces. The actual mass for a production can vary by, at most, 0.08
ounces. Create an absolute value inequality and solve it to determine the range of chocolate masses.
Answer:
[tex]2.42\,oz \leq m_{real} \leq 2.58\,oz[/tex]
Step-by-step explanation:
The inequality must be the absolute value of the difference between real mass and ideal mass less or equal to 0.08 ounces. That is to say:
[tex]|m_{real} - m_{ideal}| \leq 0.08\,oz[/tex]
[tex]|m_{real} - 2.5\,oz| \leq 0.08\,oz[/tex]
There are two extreme cases:
[tex]m_{real,max} - 2.5\,oz = 0.08\,oz[/tex] and [tex]m_{real, min} - 2.5\,oz = -0.08\,oz[/tex]
[tex]m_{real, max} = 2.58\,oz[/tex] and [tex]m_{real,min} = 2.42\,oz[/tex]
Range of chocolate masses must be:
[tex]m_{real, min} \leq m_{real} \leq m_{real,max}[/tex]
[tex]2.42\,oz \leq m_{real} \leq 2.58\,oz[/tex]
Find the slope and y-intercept of the linear equation y=8−3x
Answer:
Slope: -3
y-intercept: (0, 8)
Step-by-step explanation:
The equation y = mx + b is used for all linear equations. In this equation, m = slope and b = y-intercept.
In order to find these two variables, you must put the equation given into the y = mx + b format.
y = 8 - 3x becomes y = -3x + 8
That means that m = -3 = slope and b = 8 = y-intercept.

Carlos drew a triangle and measured two of the sides to be 8 inches and 12 inches. What has to be true of the third side?
A.
It is equal to 4 inches.
B.
It measures less than 4 inches.
C.
It measures more than 4 inches.
D.
It is 2.5 inches.
Answer:
C
Step-by-step explanation:
The triangular inequality states that a+b>c, b+c>a, a+c>b. So, 4+8=12, so a is not possible. Neither is b. D is not true either. It has to be c.

The third side of the triangle measures more than 4 inches.
What are the properties of triangle for it's side?The sum of the length of the two sides of a triangle is greater than the length of the third side. The difference between the two sides of a triangle is less than the length of the third side.
According to the given question we have,
Length of the two sides of a triangle are 8 inches and 12 inches.
Let the length of the third side be x inches.
Now, according to the properties of a triangle
"The difference between the two sides of a triangle is less than the length of the third side".
Therefore,
12 - 8 < x
⇒ 4 < x
⇒ The third side of the triangle is greater than 4 inches.
Hence, the third side of the triangle measures more than 4 inches.

The Dodgers (D) and the Angels (A) won a total of 165 games during a regular season, and the Angels won 19 games more than the Dodgers.
How many games did each team win?
btw this is solving systems of equations
Answer:
Dodgers won 73 games while angels won 73 + 19 = 92 games.
Step-by-step explanation:
The Dodgers and the angels won a total of 165 games during a regular season. The angels won 19 games more than the Dodgers .
The both team won a total of 165 games but we weren't given the game each team won but the game each team won can be gotten from the question.
Let
number of game won by Dodgers = x
number of game Angels won = x + 19
The both of them won 165 game altogether. This means the sum of their individual games won is equals to 165. Therefore,
x + x + 19 = 165
collect like terms
2x + 19 = 165
2x = 165 - 19
2x = 146
divide both sides by 2
x = 146/2
x = 73
Dodgers won 73 games while angels won 73 + 19 = 92 games.
