Answer:
The coordinate of the point Z is (4, 5)
Step-by-step explanation:
The given information are;
The coordinates of the endpoints of the directed segment QR are Q(2, 1) and R(8, 13)
The ratio of the partition of the directed line segment QR from Q to R = 1:2
The location of the point at the directed line segment is partitioned = Point Z
Therefore, we have;
The proportion of the partition segment QZ to QR is given as follows;
QZ = 1/(1 + 2) × QR = 1/3·QR
ZR = 2/(1 + 2) × QR = 2/3·QR
Which gives the coordinate of the point Z as follows;
The coordinate of the point Z = (2 + (8 - 2)×1/3, 1 + (13 - 1)×1/3)
The coordinate of the point Z = (2 + 2, 1 + 4) = (4, 5)
The coordinate of the point Z = (4, 5).

Hailey cuts a 7-inch square piece of plywood for a birdhouse. She rotates the piece 90° counterclockwise. What is the length in inches of each side of the piece of plywood after the rotation?
Can someone please help me ASAP!!
Answer:
[tex]\huge\boxed{7\ \text{inches}}[/tex]
Step-by-step explanation:
As I mentioned earlier with a single side (line), rotations do not change the size of something. Only dilations do that. This goes for both lines AND shapes.
However, if the question said she dilated the piece, then yes, the length in inches would be different. However, rotation just changes the position and nothing happens to the length.
Hope this helped!

whats the answer to 5(x−2)+3x−4= 38
Answer:
x = 6.5
Step-by-step explanation:
5(x−2)+3x−4= 38
5 times x, 5 times -2 =
5x - 10 + 3x - 4 = 38
Combine like terms
5x + 3x = 8x
8x - 10 - 4 = 38
Add 10
8x -10 +10 -4 = 38 +10 =
8x -4 = 48
Add 4
8x -4 +4 = 48 +4
8x = 52
Divide by 8
8x/8 = 52/8 =
x = 6.5
(12x – 13) m
(7x + 2) m
(2x + 17) m
E
Answer:
x = 3
Step-by-step explanation:
Since the 3 angles in the triangle are equal, then the triangle is equilateral.
Thus the 3 sides are congruent.
Equate any 2 of the sides and solve for x, that is
12x - 13 = 7x + 2 ( subtract 7x from both sides )
5x - 13 = 2 ( add 13 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3

If LMN=XYZ, which congruences are true by CPCTC?
Answer: this is how you do it
Step-by-step explanation:
For example if you have a function f(x) = x - 1, then x = 1 is a zero of this function because using it as x gives 1 - 1 = 0. The Riemann Zeta function has some zeros that are easy to find which are of little interest but there are some other ones that are harder to find which is why the are called non-trivial.

Below, you are given the 2012 value of a product and the rate at which the value is expected to change during the next 5 years. Use this information to write a linear equation that gives the dollar value V of the product in terms of the year. (Let t = 12 represent 2012.) 2012 Value Rate $48,000 $2200 decrease per year
Answer:
[tex]y = 48000 - 2200x[/tex] --- equation
[tex]y = 37000[/tex] --- value at 5th year
Step-by-step explanation:
Given
[tex]Value = \$48000[/tex]
[tex]Rate = \$2200[/tex] decrease
Required
Determine the linear equation
Determine the value at the 5th year
Represent years with x.
If the rate in 1 year is 2200,
in x years, it'll be 2200x (decrement)
So, the value (y) at x years is.
[tex]y = 48000 - 2200x[/tex]
The value at the 5th year is when x = 5.
So, we have:
[tex]y = 48000 - 2200 * 5[/tex]
[tex]y = 48000 - 11000[/tex]
[tex]y = 37000[/tex]
A television set can be purchased with a $200 down payment plus a $39.99 monthly payment. Alternatively, the television can be purchased with no money down and monthly payments of $59.99. Solve for the number of months until the payments are of equal value.
Answer:
10 months
Step-by-step explanation:
Let x denotes number of months.
Down payment of first TV = $200
Per month payment of first TV = $39.99
Total payment of first TV [tex]=200+39.99x[/tex]
Down payment of second TV = $0
Per month payment of second TV = $59.99
Total payment of second TV [tex]=0+59.99x=59.99x[/tex]
To find number of months until the payments are of equal value,
solve [tex]200+39.99x=59.99x[/tex]
[tex]200+39.99x=59.99x\\200=59.99x-39.99x\\200=20x\\x=\frac{200}{20}\\ x=10[/tex]
So, payments become of equal value after 10 months.
what is the answer for x+7=2(x-15)
Answer:
x=37 Hope this helped <3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x+7=2(x−15)
x+7=(2)(x)+(2)(−15)(Distribute)
x+7=2x+−30
x+7=2x−30
Step 2: Subtract 2x from both sides.
x+7−2x=2x−30−2x
−x+7=−30
Step 3: Subtract 7 from both sides.
−x+7−7=−30−7
−x=−37
Step 4: Divide both sides by -1
Answer:
[tex]\boxed {x = 37}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]x + 7 = 2(x - 15)[/tex]
-Use Distributive Property:
[tex]x + 7 = 2(x - 15)[/tex]
[tex]x + 7 = 2x - 30[/tex]
-Take [tex]2x[/tex] and subtract it from [tex]x[/tex]:
[tex]x + 7 - 2x = 2x - 2x - 30[/tex]
[tex]-x + 7 = -30[/tex]
-Subtract [tex]7[/tex] to both sides:
[tex]-x + 7 - 7 = -30 - 7[/tex]
[tex]-x = -37[/tex]
-Divide both sides by [tex]-1[/tex]:
[tex]\frac{-x}{-1} = \frac{-37}{-1}[/tex]
[tex]\boxed {x = 37}[/tex]
So, the value of [tex]x[/tex] is [tex]37[/tex].
Simplify the following expression:

A x − 3y + 8z
B 2x − 2y + 8z
C 3y + 8z
D−3y + 8z
Answer:
D) -3y + 8z
Step-by-step explanation:
2x - 2y + 5z - 2x - y + 3z
first, group the same variables together.
2x - 2x - 2y - y + 5z + 3z
then, this step which I don't have a name for.
2x - 2x = 0x.
-2y - y = -3y
5z + 3z = 8z
0x - 3y + 8z
or, -3y + 8z

A test has a mean of 80 with a standard deviation of 4. Which of the following scores is within one standard deviation of the mean?
A
75
B
77
С
BO
D
90
E
09
Answer:
B
Step-by-step explanation:
Mathematically, we shall be using the z-score here
Z-score = (x-mean)/SD
From the question, mean = 80 and SD = 4
So we want to get the option in the question that has a z-score of 1 or below
Let’s look at 75
80-75 = 5 ( this is clearly above 1 standard deviation of 4)
For 77;
80 -77 = 3
This is less than the standard deviation of 4, meaning it is within 1 standard deviation of the mean
Option B) is correct.
Step-by-step explanation:
Given :
Mean [tex](\mu)[/tex] = 80
Standard Deviation [tex](\sigma)[/tex] = 4
Calculation :
We have to find the score that would be 1 deviation from the mean. Which means, the interval [tex](\mu-\sigma, \mu+\sigma)[/tex]
[tex]\mu-\sigma = 80-4=76[/tex]
[tex]\mu+\sigma =80+4=84[/tex]
The interval is (76,84)
Therefore, option B) is correct.

Answer:
The domain is continuous and the weight y of x identical hardcover books
Step-by-step explanation:
Discrete means non continuous data. This is continuous and equal so the domain is continuous.
Also, precipitation each week can vary so that won't work. Eating carrots each day can also vary so that doesn't work. The cost of an item can vary almost every day! So that is not true.
Therefore it is the last one, because it is identical and all of the coordinates make (1,3).

3) Car A and B travel in opposite directions. Both cars leave the same location at the same time. Car A is traveling west at a speed of 10 mph more than Car B, which is headed east. Find the speed of Car A if the two cars are 300 miles apart after traveling 3 hours. Chart is optional. Include units in your answer. *
Let, speed of car B is -x.
So, speed of car A is x + 10.
Relative speed of A w.r.t B is ,
[tex]v_{ab}=(x+10)-(-x)\\\\v_{ab}=2x+10\ mph[/tex]
So, time taken by A to travel 300 miles relative to B given by 3 hours .
[tex]v_{ab}=2x+10\\\\\dfrac{300}{3}=2x+10\\\\x = 45 \ mph[/tex]
Therefore, speed of car A is 45 + 10 = 55 mph.
Hence, this is the required solution.
