Given the endpoint x(11,-2) and the midpoint (4,3) find the missing endpoint y. Write answer as order pair.
Answers
9514 1404 393
Answer:
(-3, 8)
Step-by-step explanation:
For m the midpoint of xy, we have ...
m = (x+y)/2 ⇒ y = 2m-x
y = 2(4, 3) -(11, -2) = (2·4 -11, 2·3 +2)
y = (-3, 8)

If 16x-2=30 what is the value of 8x-4?
Answers
16x - 2 = 30
+ 2 +2
16x = 32 , x=2
Substitute :
8x - 4 = 8(2) - 4 = 16-4 = 12!
Answer:
12
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define 1st equation
16x - 2 = 30
Step 2: Solve for x
Add 2 on both sides: 16x = 32Divide 16 on both sides: x = 2Step 3: Solve equation
Define: 8x - 4Substitute: 8(2) - 4Multiply: 16 - 4Subtract: 12And we have our final answer!
Given that n^2/3 = 8 and n> 0
work out the value of n.
Give your answer in the form a square root b where a and b are integers.
Answers
Answer:
16[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the rule of exponents/ radicals
[tex]a^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{a^{m} }[/tex] , then
[tex]n^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{n^2}[/tex] , then
[tex]\sqrt[3]{n^2}[/tex] = 8 ( cube both sides )
n² = 8³ ( take the square root of both sides )
n = [tex]\sqrt{8^3}[/tex]
= [tex]\sqrt{512}[/tex]
= [tex]\sqrt{256(2)}[/tex]
= [tex]\sqrt{256}[/tex] × [tex]\sqrt{2}[/tex]
= 16[tex]\sqrt{2}[/tex]
A tree is currently 10 feet tall and grows 2 feet per year. Show your work for full credit.
a. Model this scenario with an arithmetic sequence in explicit form. (2)
b. Rewrite the explicit form of the sequence using function notation. (2)
c. How tall will the tree be in 15 years? (1)
Answers
Answer:
(a) An = 2n +8
(b) F(n) = 10 + (n-1)2
(c) 38ft tall
Step-by-step explanation:
The tree is currently 10 feet long and grown 2 feet per year.
The arithmetic sequence is
10 , 12, 14 , 16 , 18 ..............
a( initial value) = 10 , d (common difference) = 2
Explicit forms
(a) An = a +(n-1)d
An = 10 + (n-1)2
= 10 + 2n -2
An = 2n +8
(b) F(n) = 10 + (n-1)2
(c) Height of the tree after 15 years
F(15) = 10 + (15-1)2
= 10 + 28
= 38ft
So the tree will be 38ft tall after 15 years.

A triangles angles add up to 180 degrees, and along with that the triangles are directly corresponding or are the same as each other meaning the angles are mirrored.
With that in mind we subtract the angles we have from 180 to find the missing angle.
180-70-30
180-100
80
D=80 degrees
Answer:
∠ D = 80°
Step-by-step explanation:
Δ BCA and Δ DCE are congruent ( SAS postulate )
Thus corresponding angles are congruent, thus
∠ D = ∠ B
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles in Δ ABC from 180° to find ∠ B
∠ B = 180° - (30 + 70)° = 180° - 100° = 80°, then
∠ D = 80°

Step-by-step explanation:
∠X ≅∠Z : Given
∠ZYV≅∠XYU
∠ZVY≅∠XUY Because ∠ZYV≅∠XYU, ∠X ≅∠Z.
So ∠YVW≅∠YUW
Draw VU
ΔVWU is an isosceles triange so ∠UVW≅∠VUW
So ∠YVU≅∠YUV
Therefore ΔYVU is also an isosceles triangle and YV = YU
So ΔZYV≅ΔXYU ( ASA)
So XU = ZV ( because of CPCTC)
Therefore XU + WU = ZV = VW : XW = ZV
ΔXWV ≅ΔZWU ( ASA)

Laqueta has three times as many quarters as Pablo if they each spend $.50 Laqueta will have five times as many quarters as Pablo how many quarters do Laqueta and Pablo have now?
Answers
Answer:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = 12
Step-by-step explanation:
Given that:
Laqueta has three times as many quarters as Pablo.
They both spend $0.50.
After that Laqueta will have 5 times as many quarters as Pablo.
To find:
Number of quarters with Laqueta and Pablo now?
Solution:
Let number of quarters with Laqueta = [tex]x[/tex]
Let number of quarters with Pablo = [tex]y[/tex]
As per given statement:
[tex]x=3y ..... (1)[/tex]
In $0.50, there are 2 quarters:
After spending $0.50, number of quarters left with both of them:
Number of quarters left with Laqueta = [tex]x[/tex] - 2 = [tex]3y-2[/tex]
Money left with Pablo = [tex]y[/tex] - 2
As per given statement:
[tex]3y-2 = 5(y-2)\\\Rightarrow 3y-2 = 5y-10\\\Rightarrow 2y = 8\\\Rightarrow y = 4[/tex]
Therefore, the answer is:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = [tex]3 \times 4[/tex] = 12
