Answer:
Step-by-step explanation:
So you need to take two points off the graph. (x,y) and (x,y)
After that use those points to plug it into this equation
your gonna want to take the Y points from both and subtract from each other.
Do the same for the X points.
Y2-Y1
X2-X1
You'll then divide The Y by the X and that the Rise over Run. When you graph that. That'll be your answer.
whats {(5-8)+5}+10/2-20/5
Answer:
{(5-8)+5}+10/2-20/5= 3
Step-by-step explanation:
{(5-8)+5}+10/2-20/5
PEMDAS
Parentheses first
5-8 = -3
( -3 + 5 ) + 10/2 - 20/5
-3 + 5 = 2
2 + 10/2 - 20/5
10/2 = 5
2 + 5 - 20/5
2 + 5 = 7
20/5 = 4
7 - 4 = 3

Which expressions are equivalent to 25x4 −64? Select three options. 25x4 + 40x − 40x − 64 25x4 + 13x − 13x − 64 (5x2 + 8)(5x2 − 8) (x2 + 13)(x2 – 13) (5x2 – 8)2
The equivalent expression of 25 - 64 are "a), b) and c)"
The given expression is:
25 - 64
To find, the equivalent expressions are:
a) 25 + 40x - 40x - 64
= 25 - 64, is the equivalent expression.
b) 25 + 13x - 13x - 64
= 25 - 64, is the equivalent expression.
c) (5 + 8)(5 - 8)
Using the algebraic identity,
(a + b)(a - b) =
=
= 25 - 64, is the equivalent expression.
d) ( + 13)( - 13)
Using the algebraic identity,
(a + b)(a - b) =
=
= - 169, is not a equivalent expression.
e)
Using the algebraic identity,
, is not a equivalent expression.
∴ The equivalent expression of 25 - 64 are "a), b) and c)".
Answer: option A, B, C are equivalent to [tex]25x^4-64[/tex].
We check each option by simplifying:
A) [tex]25x^4 + 40x - 40x - 64 = 25x^4-64[/tex].
B) [tex]25x^4 + 13x - 13x - 64 = 25x^4-64[/tex]
C) [tex](5x^2 + 8)(5x^2 - 8)=(5x^2)^2-8^2=25x^4-64[/tex]
D) [tex](x^2 + 13)(x^2 - 13)=(x^2)^2-13^2=x^4-169[/tex]
E) [tex](5x^2 - 8)^2=(5x^2)^2-2(5x^2)(8)+8^2=25x^4-80x^2+64[/tex].
So option A, B, C are equivalent to [tex]25x^4-64[/tex].

What is mass if force is 45 N and acceleration is 39 m/s/s?
Answer:
The answer is 1.15 kgStep-by-step explanation:
To find the mass of an object given it's acceleration and the force acting on it we use the formula
[tex]mass = \frac{force}{acceleration} \\ [/tex]
From the question
force = 45 N
acceleration = 39 m/s²
We have
[tex]force = \frac{45}{39} = \frac{15}{13} \\ = 1.153846...[/tex]
We have the final answer as
1.15 kgHope this helps you

There is 3/8 of A PIZZA IN ONE BOX AND 1/4 OF A PIZZA IN ANOTHER BOX HOW MUCH DO YOU HAVE ALTOGETHER
Answer:
5/8
Step-by-step explanation:
I believe this should be fraction addition (?)
3/8 + 1/4
8, 4: 8 = 3/8 + 2/8
= 3 + 2/8 = 5/8
You have a total of (5/8)th part of a complete pizza.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that you have 3/8 of a pizza in one box and 1/4 in another box.
Assume that the total pizza you have is denoted by [x].
[x] = (3/8 + 1/4) of a pizza
[x] = (3 + 2)/8 of a pizza
[x] = 5/8 of a pizza
Therefore, you have a total of (5/8)th part of a complete pizza.

Jim received notice from his employer that the equation to calculate his salary was changing. Currently he makes $300 per week plus 4% commission on sales. The new equation will be $450 plus 2% commission on sales. Which equation shows the amount in sales he will need for his salary to be the same?
Answer:
Sales= $750Step-by-step explanation:
let sale be x
and his salary be y
y=300+0.4x----------1 the old equation
y=450+0.2x----------2 the new equation
for his salary to be the same
equation 1 and 2 must be equal hence
300+0.4x=450+0.2x
solving for x we have
300-450+0.4x-0.2x=0
-150+0.2x=0
0.2x=150
x=150/0.2
x=$750

O y
y=
k
where y is the constant of proportionality
Answer:
B. [tex] y = kx [/tex] , where k is the constant of proportionality.
Step-by-step explanation:
Given that quantity x and y is directly proportional to each other, which means as one variable increases, the other increases as well. Thus, the constant of proportionality, which is often denotes with the alphabet k, can be represented by the following equation:
[tex] y = kx [/tex] , where, k is the constant of proportionality.
Constant of proportionality, k, is gotten when you divide the value of y by the value of x.

Answer:
105
Step-by-step explanation:
since its a straight line it would add up to 180 degrees so 52 + 23 + 75 and you need 180 so 180-75 which gives 105 which is the missing angle
Answer:
105 degrees
Step-by-step explanation:
First add the angles that you already know, 52 + 23 = 75, then since we know that the whole thing is a straight angle (180 degrees) 180-75 = 105 degrees.
Hope this helped!
