Answer:
The two numbers are 157 and 13
Step-by-step explanation:
Let x and y be the two numbers
x+y = 170
x-y =144
Add the two equations together
x+y = 170
x-y =144
-------------------
2x= 314
Divide by 2
2x/2 = 314/2
x =157
Now find y
x+y = 170
157+y = 170
y = 170-157
y =13

Answer:
7 11/12
Step-by-step Explanation:
2 1/2 = 2 2/4
2 2/4 + 1 3/4 = 3 5/4 = 4 1/4
4 1/4 = 4 3/12
3 2/3 = 3 8/12
4 3/12 + 3 8/12 = 7 11/12

Check all that apply
Answer:
[see below]
Step-by-step explanation:
Vertical angles are simply opposite angles that are made from intersecting lines.
The most appropriate pairs would be vertical pairs:
∠NSI and ∠TSW
∠NST and ∠ISW
The angles are opposite of each other and formed from the two lines.
Hope this helps.

What is the inverse of the function f(x) = 2x + 1?
Answer:
[tex]f(x)^{-1}=\frac{x-1}{2}[/tex]
Step-by-step explanation:
start by replacing f(x) for y:
y = 2x + 1
switch y and x:
x = 2y+1
solve for x by first subtracting 1 from both sides:
2y = x-1
divide 2 from both sides:
y = [tex]\frac{x - 1}{2}[/tex]
replace y with [tex]f(x)^{-1}[/tex]:
[tex]f(x)^{-1}=\frac{x-1}{2}[/tex]
The y-values that a function approaches when the x-values are extremely large or extremely small. This is called the function's

Please help me with this geometry question
Answer:
2) 40
Step-by-step explanation:
the perimeter of Rhombus =
4 × (√(12/2)²+(16/2)² )
= 4× (√6²+8²)
= 4× (√100)
= 4×10
= 40
Q) 4 × (√(12/2)²+(16/2)² )
→ 4 × (√6²+8²)
→ 4 × (√100)
→ 4 × 10
→ 40 is the perimeter of rhombus.
-3 (7x + 7) = -38 - 4x
Answer:
x = 1
Step-by-step explanation:
-3 (7x + 7) = -38 - 4x
-3(7x)-3(7) = -38 - 4x
-21x - 21 = -38 - 4x
-21x+4x = -38+21
-17x = -17
x = -17/-17
x = 1
Answer:
x = 1.
Step-by-step explanation:
-3(7x + 7) = -38 - 4x
Use distributive property to get:
-21x - 21 = -38 - 4x
Add 4x to both sides to get:
- 17x - 21 = -38
Add 21 to both sides to get:
- 17x = -17
x = 1.
I hope this helps, have a nice day.
25 POINTS Find the slope of the line khan academy
Answer:
-8/5
Step-by-step explanation:
Using the points given ( -1,4) and (4,-4)
We can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -4 -4)/(4- -1)
= (-4 -4)/(4+1)
= -8/5

How do the perimeters of the triangles compare? Original: height-18, slant-30, length-24 Scaled: height-6, slant-10, length-8 A) the scaled triangles perimeter is 3x's larger than the original triangles perimeter. B) the scaled triangles perimeter is 6x's smaller than the original triangles perimeter C) the scaled triangles perimeter is 1/9 the size of the original triangles perimeter D) the scaled triangles perimeter is 1/3 the size of the original triangles perimeter
Answer:
D) the scaled triangles perimeter is 1/3 the size of the original triangles perimeter
Step-by-step explanation:
Given
Original:
[tex]Height = 18, Slant = 30, Length =24[/tex]
Scaled:
[tex]Height =6, Slant=10, Length=8[/tex]
Looking at the dimension of both triangles, The relationship between the original and the scaled copy is:
[tex]Scaled = \frac{1}{3} * Original[/tex]
Hence, the perimeter is:
[tex]Perimeter (Scaled) = \frac{1}{3} * Perimeter (Original)[/tex]
The diagram shows a triangle ABC in which AB= 6 cm, BC=8 cm and ABC = 90°.
Calculate the length of AC.
The answer should be 12. please help with explanation and calculation!!!
Answer:
AC = 10
Step-by-step explanation:
This is a right triangle
use the pythagorean theorem
a² + b² = c²
6² + 8² = c²
36 + 64 = c²
100 = c²
Take the square root of both sides
10 = c
AC = 10
The correct answer is 10 not 12

36) In the diagram, the coordinates of endpoints A and B are (-3, 9) and (9,5). Find the length from A to E?
Step-by-step explanation:
the length of AB = √(9+3)²+(5-9)²
= √144+16=√180 = 6√5
the length from A to E = ⅜× 6√5
= 2.25 √5 or 5.03
Length of AB,
→ √(9+3)² + (5-9)²
→ √144+16
→ √180
→ 6√5
Length from A to E,
→ ⅜ × 6√5
→ 2.25 √5
→ 5.03
tan145+tan85/1-tan145*tan85 as asingle funciton
Answer:
Step-by-step explanation:
Tan 145 = - 0.7002
Tan 85 = 11.43
Tan 145 + tan 85 = 10.7298
1 - tan(145)* tan(85) = 9.003
(Tan(145) + Tan(85)) / (9.003)
= 10.73 / 9.003
= 1.1918
I misread the question. If you mean
(Tan145+tan85) /1-tan145*tan85 (brackets are really important here)
then the answer is
Tan(145 + 85)
= Tan(230)
= 1.1918

Answer:
y = 0
Step-by-step explanation:
Let's use the addition method.
2x + y - 10 = 0
x - y - 5 = 0
Write the first equation as is. Write below it the second equation multiplied by -2 on both sides. Then add the equations.
2x + y - 10 = 0
(+) -2x + 2y + 10 = 0
--------------------------------
3y = 0
Divide both sides by 3.
y = 0
Answer: y = 0
What does 2x+4y=12 solve for?
Answer:
Hi, there for x it will be x=−2y+6
But if your solving for y it will be [tex]y=-\frac{1}{2}x+3[/tex]
Hope this Helps :)
Step-by-step explanation:
Let's solve for x.
2x+4y=12
Step 1: Add -4y to both sides.
2x+4y+−4y=12+−4y
2x=−4y+12
Step 2: Divide both sides by 2.
[tex]\frac{2x}{2}=\frac{-4y+12}{2}[/tex]
x=−2y+6
2.
Let's solve for y.
2x+4y=12
Step 1: Add -2x to both sides.
2x+4y+−2x=12+−2x
4y=−2x+12
Step 2: Divide both sides by 4
[tex]\frac{4y}{4} =\frac{-2x+12}{4}[/tex]
[tex]y=-\frac{1}{2} x+3[/tex]
If 4p + 3q + 2r = 3 and -4p - 2q - 2r = 4, then q = ?
(A) 0
(B) 2
(C) 3
(D) 4
(E) 7
Answer:
E
Step-by-step explanation:
Label the two equations:
4p +3q +2r= 3 -----(1)
-4p -2q -2r= 4 -----(2)
(1) +(2):
4p +3q +2r -4p -2q -2r= 3 +4
Grouping like terms together:
4p -4p +3q -2q +2r -2r= 7
Simplify:
q= 7
