Answer:
47
Step-by-step explanation:
2 sf for this number means to the nearest 1 000
1 000 ÷ 2 = 500
So length of chain on roll is 26 000 ± 500
Greatest guaranteed number given by 25 500 ÷ 540 = 47.33... so answer is 47.
the table shows ordered peirs of the function y= 8 - 2x what is the value of y when x = 8
Answer:
y = -8
Step-by-step explanation:
All we need to is substitute for x and solve for y.
y = 8 - 2x
y = 8 - 2(8)
y = 8 - 16
y = -8
Best of Luck!

Use the table here to answer the questions below.
1) Explain what Pablo did in each step of his work.
2) Explain what Karla did in each step of his work.
3) Are Pablo and Karla correct?
Please help due today!!
Answer:
Pablo Used the Commutative property to Reorder the terms. Pablo then Combined all his like terms. Pablo then Divided 21 by 3x to get 3(7+x). Pablo then subtracted 7 from 13. He got x = 6
Pablo did his math wrong.
Karla Did her work correctly. Karla used the commutative property to reorder the terms. She then combined her like terms. She subtracted 21 from itself and 39, leaving 3x and 18 on different sides of the equal sign. She divided 3x by 3 which equals x and 18 by 3 which equals Karla is correct.

f(x) = 8x - 11
f(9) =
Answer:
61
Step-by-step explanation:
hi! we can start off by plugging in the number 9 for x in the equation.
f(x)=8x-11)
f(9)= 8(9)-11
= 72-11
=61
hope this helps.
What is y=3x+13 in standard form?
Answer:
3 x − y = − 13
Step-by-step explanation:
Any equation that relates the first power of x to the first power of y produces a straight line on an x-y graph. The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept. Converting from slope intercept form to standard form takes little more than basic arithmetic.
TLDR:
To convert from slope intercept form y = mx + b to standard form Ax + By + C = 0, let m = A/B, collect all terms on the left side of the equation and multiply by the denominator B to get rid of the fraction.
Answer:
3x - y = -13
Step-by-step explanation:
y = mx + b
(This is the slope intercept form)
We want to change it to standard form, which is:
Ax + By = C
We want to rearrange as many of the numbers as we can, without actually changing the problem!
Ax = 3x
By = y
C = 13
So we must move the numbers from one side to another.
Whatever you do to one side, you do to the other.
y = 3x + 13
-3x + y = -3x - y
--------------------
-3x + y = 13
Since we can't have our "Ax" as a negative multiply everything by -1
-1[-3x + y = 13]
3x - y = -13
That is your answer.
In the transformed quadratic function

O (5, 4)
O (3, -4)
o (-5, -4)

Answer:
(5, -4)Step-by-step explanation:
f(x) = a(x - h)² + k ← the vertex form of quadratic function where vertex is: (h, k)
[tex]\left{\big{f(x)=a(x-h)^2+k}\atop \big{g(x)=3(x-5)^2-4}\right\}\implies a=3\,,\ \underline{h=5\,,\ k=-4}[/tex]

how do you solve this pls help!!!
Answer:
y = 1
x = -0.75
Step-by-step explanation:
The alternate angles theorem states that if two parallel lines are cut by a transversal, then each pair of alternate interior angles are equal.
21y - 1 = 4x + 23
21y - 24 = 4x
5.25y - 6 = x
21y - 1 = 4x + 23
21y = 4x + 24
y = 4/21(5.25 - 6) + 1.14
y = 1 - 1.14 + 1.14
y = 1
5.25(1) - 6 = x
-0.75 = x
round to the tenth. i need the answer plss
Answer: D
Step-by-step explanation:
Answer:
C=6.4ft
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + 5^2 = c^2
4 + 4 = 16
5 + 5 = 25
16 + 25 = c^2
41 = c^2
Now you will need to find the square root of 41 which gives you 6.40 and you just round to nearest tenth..

A turtle traveled
1/10 miles in 1/2 hour. What was the turtle's rate in miles per hour?
A: 1/20
B: 1/12
C: 1/6
D: 1/5
The turtle's rate in miles per hour is 1/5 miles/hr.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that a turtle traveled 1/10 miles in 1/2 hour.
Rate is defined as the distance travelled in a unit hour {1 hour}.{R} = x/t.We can write the rate as -
{R} = (1/10)/(1/2)
{R} = (1/10) x 2
{R} = 1/5 miles/hr
Therefore, the turtle's rate in miles per hour is 1/5 miles/hr.

Identify the slope and y-intercept from the following equation.
Answer:
The slope is 2/5 and the y intercept is -4
Step-by-step explanation:
The slope is always the coefficient to x
Answer:
slope = [tex]\frac{2}{5}[/tex] , y- intercept = - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{2}{5}[/tex] x - 4 ← is in slope- intercept form
with slope m = [tex]\frac{2}{5}[/tex] and y- intercept c = - 4
What is the value of n?
What is the value of n?
Answer:
42
Step-by-step explanation:
You get 42 by looking at the denominators 7 and 21. You times by 3 to get from 7 to 21, so you times 14 by 3 to get n, which is 42.
Answer:
42
Step-by-step explanation:
On the bottom 7 was multiplied by 3 so you would do the same to 14.
