Help me please i don't understand
Answer:
4
Step-by-step explanation:
Because you use trial and error to see what x is and it says integet meaning 1,2,3,4,5,6... and their opposites.
Answer:
x ≈ 5 using math and x ≈ 4 using trial and error
Step-by-step explanation:
[tex]6^x = 3800[/tex]
[tex]x = log_{6}*3800[/tex]
x ≈ 4.6 ≈ 5
Hope this helped!
-----------------------------------------------------------------------------------------------
Trial and Error:
6 ^ 4 = 1276
6 ^ 5 = 7776
3800 is closer to 1276, so x = 4

6. Tell whether the lines are parallel, perpendicular, or neither. *
Line 1: (-3,-1) and (-7,-2)
Line 2: (2.-1) and (8,4)
Parallel with a slope of 1/4
Parallel with a slope of 5/6
Perpendicular with a slope of 1/4 and
Perpendicular with a slope of 1/4
Neither, slopes are 1/4 and 5/6
O
Neither, slopes are 3/10 and 1/2
Answer:
Neither, slopes are 1/4 and 5/6
Step-by-step explanation:
Let's find the slope for Line 1: (-3,-1) and (-7,-2)
m1 = (-2+1)/ (-7+3)
= -1/-4
=1/4
Line 2: (2.-1) and (8,4)
m2= (-4+1)/ (8-2)
= -3/6
= - 1/2
These slope values are not the same, so the lines are not parallel. The slope values are also not negative reciprocals, so the lines are not perpendicular. Then the answer is
Neither, slopes are 1/4 and 5/6
solve y
y=8x-x^2
y=2x
STEP BY STEP SOLUTION PLEASE HELP
Answer:
y=12
Step-by-step explanation:
y=2x ,so 2x=8x-x^2
x^2=8x-2x
x^2=6x
x^2/x=6x/x
x=6
y=2x ,2(6)
y=12
The length of a side of a square is 4x – 1.
Express the area of the square in terms of x.
Answer:
16x^2 - 8x + 1
Step-by-step explanation:
1. The area of a square can be represented as s^2 or (s)(s), where s = side.
2. (Solving)
Step 1: Set up expression
[tex](4x-1)^2[/tex] [tex](4x-1)(4x-1)[/tex]Step 2: Apply the FOIL method (first, outside, inside, last)
[tex](4x)(4x)+(4x)(-1)+(-1)(4x)+(-1)(-1)[/tex] [tex]16x^2 -4x -4x +1[/tex]Step 3: Simplify.
[tex](16x^2)+(-4x-4x)+(1)[/tex] [tex]16x^2 -8x + 1[/tex]Therefore, the area of the square in terms of x is 16x^2 - 8x + 1.

Answer:
N/A
Step-by-step explanation:
We should first simplify the right side, and doing so will get x/3+6=x/3+10. WE then subtract x/3 on both sides to get 6=10. Since this cannot be true, there are no solutions.
Answer:
no solution
Step-by-step explanation:
[tex]\frac{x}{3}[/tex] + 6 = 2([tex]\frac{x}{6}[/tex] + 5) ← distribute parenthesis by 2
[tex]\frac{x}{3}[/tex] + 6 = [tex]\frac{x}{3}[/tex] + 10 ( subtract 6 from both sides )
[tex]\frac{x}{3}[/tex] = [tex]\frac{x}{3}[/tex] + 4 ( subtract [tex]\frac{x}{3}[/tex] from both sides )
0 = 4 ← False statement
This indicates the equation has no solution

Here's the question
Use the mapping (x+3, y-5), for the transformation of triangle ABC with vertices A(-2, -4), B(0, 0), and C(1, -3), find the coordinates of the new triangle A’B’C’ . You must show all your work.
And then here is the answer
You’re going to go left side three points and down five for every point on the graph (ABC) and once you do that label the ABC marks with an apostrophe like so; A’B’C’ for every time you change places

Ms. Sublett's math class is putting three numbers (0.3, 1/4, and 20%) in order from least to greatest. What order should the numbers be from least to greatest?
Answer:
least to greatest
20% , 1/4, 0.3
20% = 1/5 = 0.2
0.3 = 3/10 = 30%
1/4 = 25% = 0.25
Will the answer be the same when you switch the variables like for example
b(a-6) = ba-6b would it also be ab-6b?
which one is correct can someone plss explain this to me!
Answer:
they are both correct due to the commutative property
-0.1b = 3.8, what is b?
-0.1b = 3.8 ; Get b alone
3.8 / -0.1 = -38 ; Turns negative, and 3.8 / 0.1 = 38
b = -38
Solve the formula c = 5p + 215 for p
Answer:
1/5c -43 =p
Step-by-step explanation:
c = 5p + 215
Subtract 215 from each side
c-215 = 5p +215-215
c-215 = 5p
Divide each side by 5
c/5 -215/5 = 5p/5
1/5c -43 =p
The following represents slopes of two lines. Which answer choice describes the two lines? m = 7 and m = -7
Answer:
m = 7 can also be y=7x+1 is positive and shows acceleration or ascending lines steep y axis 1 and x axis 0 ascending to 1 or above and when y = 7 x =1 see attached.
m = -7 is negative and shows deceleration of 1 as we add 1 here too. Or can be any number for y intercept see attached.

The diagram shows a trapezium PQRS.
Calculate the area of the trapezium PQRS.
Answer:
AREA = 35cmStep-by-step explanation:
Formula in finding the trapezoid's area:
USE THIS FORMULA!: 1/2 × altitude × (base [tex]_{1}[/tex] + base [tex]_{2}[/tex])(note: altitude is also known as the height)
Area = 1/2 × 5 × (6 + 8)
A = 1/2 × 5 × 14
A = 2.5 × 14
A = 35
The area of your trapezium is 35!

Answer:
Reflexive property
Step-by-step explanation:
The reflexive property of congruence states that any geometric shape is congruent to itself.
Answer:
C) Symmetric Property
Step-by-step explanation:
The Symmetric Property states that If A is congruent to B, then B is also congruent to A. This implies that the congruence is symmetric.
Khan Academy also states that:
When a relation has a symmetric property, it means that the if relation is true between two things, it is true in either order. If VW ≅ XY, then XY ≅ VW.
Therefore, the correct answer is C) Symmetric Property.

The perimeter of an equilateral triangle is 9n - 12. Write an expression to represent the length of each side.
Answer:
[tex]9n - 12 \rightarrow \frac{1}{3} (9n - 12) \\ = \frac{3}{3} (3n - 4) \\ l = 3n - 4[/tex]
The perimeter of an equilateral triangle is 9n - 12. Write an expression to represent the length of each side.
Solution:The perimeter of an equilateral triangle is 9n - 12.We know, perimeter of a triangle is the sum of the three sides of the triangle.Also, in an equilateral triangle, all the sides are equal.Therefore, the length of each side of the triangle
[tex] = \frac{9n-12}{3} \\ = \frac{3(3n - 4)}{3} \\ = 3n - 4[/tex]
Answer:The length of each side of the triangle is 3n-4.
