Explain how to isolate the variable in the equation−2/3+7=15. solve for n
Answers
Answer:
n = - 0.0833
Step-by-step explanation:
Given expression
[tex]\frac{-2}{3n } +7 = 15[/tex]
Cross multiplication , we get
[tex]\frac{-2}{3n } = 15 -7[/tex]
[tex]-2 = 8 X 3 n[/tex]
⇒ [tex]\frac{-2}{24} = n[/tex]
n = - 0.0833

Answers
g(x)--3x^2-4x+1
what is f(x)-g(x)
f(x)-g(x)= x^2 + 2x - 5 - 3x^2 - 4x + 1

x^2 - 3x^2 + 2x - 4x - 5 + 1

Find the slope of the line y = 5/8x - 1/2
Answers
Answer:
slope = [tex]\frac{5}{8}[/tex]
Step-by-step explanation:
Slope-intercept form is the way in which an equation is written to easily identify the line's slope and y-intercept. It is represented by the equation y = mx + b, in which m represents the slope.
By looking at the equation, we can see that it takes the y = mx + b format - y is isolated - therefore it is in slope-intercept form. Remember that the number in place of the m would represent the slope - and in this case, that number is [tex]\frac{5}{8}[/tex].
Final Answer:
[tex]\sf{Slope = \dfrac{5}{8}}\\\sf{Y-intercept: -\dfrac{1}{2}}[/tex]
In-depth explanation:
The question is asking us to find the slope of the line, whose equation is;
[tex]\leadsto\quad\bf{y=\dfrac{5}{8}x-\dfrac{1}{2}}[/tex]
The format of this equation is: [tex]\boldsymbol{\sf{y=mx+b}}[/tex]. This is known as slope-intercept; it's the most common way of writing the equation of a line.
In y = mx + b, the variable "m" denotes the slope, or the rate of change, of a line; b denotes the y-intercept, or the point where the line intercepts the y-axis.
Also, the slope is the number before x, while b is the constant term.
Similarly, the slope is 5/8 and the y-intercept is -1/2.

The radius of a circular sign is 12 inches. Equal parts of the sign are painted red and yellow. How many square inches are painted in each color? Use 3.14 for Pi
Answers
Answer:
226.08 square inches
Answer:
Step-by-step explanation:
First we find Area
12^2* 3.14= 452.16
Then we know that half of the sign is painted red and the other half is painted yellow
452.16 / 2 = 226.08
226.08 square inches is painted yellow and 226.08 square inches is painted red

write the slope intercept form of the equation of each line
Answers
Answer:
Y= - 1/5x-4
Step-by-step explanation:
slope intercept form: y=mx+b
Slope formula: rise/run
(5,-5) AND (0,-4)
-5+-4= -1
5+0= 5 AKA - [tex]\frac{1}{5}[/tex] or -1/5
The m in y=mx+b is the slope, the equation above is the sloe formula meaning -1/5 is the slope. The b is the y, when it is at 0. The y at 0 for this equation is -4. Thus, when plugging in the equation, y=-1/5x-4
Solve the following system of equations.
3x + 5y = 5
7x + 5y = 25

Decide whether or not the relation is a function.
[(0,1), (-5,4), (0,2), (5,-4)]
Answers
Answer:
The relation {(0,1), (-5,4), (0,2), (5,-4)} does NOT represent the relation.
Step-by-step explanation:
We know that a function is a relation where each input or x-value of the X set has a unique y-value or output of the Y set.
In other words, we can not have duplicated inputs as there should be only 1 output for each input.
Given the relation
{(0,1), (-5,4), (0,2), (5,-4)}
From the given relation is clear that the input value x = 0 is repeated twice.
In other words, the input value x = 0 is duplicated.
As we have already mentioned that we can not have duplicated inputs as there should be only 1 output for each input.
Therefore, the relation {(0,1), (-5,4), (0,2), (5,-4)} does NOT represent the relation.
