What is y = mx + b mean for functions
Answer:
Slope-Intercept Form. A function whose graph is a line or a part of a line is called a linear function. In general, a linear function is a function that can be represented by an equation in the form y = mx + b. The form y = mx + b, or f(x) = mx + b, is called the slope-intercept form of a linear equation

r = s
by Pythagoras theorem :
r² + s² = (9√2 )²
s²+s²= 9 × 9 × 2
2s²= 9× 9×2
s²= 9 × 9
s= √9× 9
s = 9
r= s = 9 units .

Expand.If necessary, combine like terms (2x-3)(2x-3)
The expression (2x-3)(2x-3) can be written as (2x-3)² or 4x² - 12x + 9 after expanding by using the identity (a - b)² = a² -2ab + b²
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have given an expression:
= (2x-3)(2x-3)
After multiplication:
= (2x-3)²
We can also expand the above expression by using the identity:
(a - b)² = a² -2ab + b²
= 4x² - 12x + 9
Thus, the expression (2x-3)(2x-3) can be written as (2x-3)² or 4x² - 12x + 9 after expanding by using the identity (a - b)² = a² -2ab + b²

-3x = 12
i really need to know this for my math exam
Answer:
x = -4
Step-by-step explanation:
[tex] - 3x = 12[/tex]
Lets divide both the sides by -3.
[tex] = > \frac{ - 3x}{ - 3} = \frac{12}{ - 3} [/tex]
[tex] = > x = - 4[/tex]
x= -4
-3x=12
divide x by -3 and do the same on the other side
12÷(-3)= -4
hence, x= -4

if Nandi and thabo share R15,00 in the ratio 1:2 how many rands does each get
Answer:
[tex]\boxed{\textsf{ The amount shared by Nandi is \textbf{ Rs 500. }.}}[/tex]
[tex]\boxed{\textsf{ The amount shared by Thabo is \textbf{ Rs 1,000. }.}}[/tex]
Step-by-step explanation:
Given that Nandini and Thabo share Rs 1500 in the ratio 1:2 . And we need to find how much each gets . So lets take the given ratio be 1x :2x . Now here we can find the share of both as ,
[tex]\qquad\boxed{\boxed{\sf Share =\dfrac{ Ratio \ number }{Sum \ of\ ratio\ nos. }\times Amount }}[/tex]
Hence here the sum of ratio numbers would be 1+2 = 3 . Here the ratio number of Nandi is 1 and that of Thaboo is 2 . So ,
Share of Nandi :-
[tex]\sf\implies Share =\dfrac{ Ratio \ number }{Sum\ of\ ratio\ nos. }\times Amount \\\\\sf\implies Share_{(Nandi)}= \dfrac{1}{1+2}\times Rs\ 1,500 \\\\\sf\implies Share_{(Nandi)}= \dfrac{1}{3}\times Rs\ 1,500 \\\\\sf\implies \boxed{\pink{\frak{ Share_{(Nandi)}= Rs\ 500 }}}[/tex]
[tex]\rule{200}2[/tex]
Share of Thabo :-
[tex]\sf\implies Share =\dfrac{ Ratio \ number }{Sum\ of\ ratio\ nos. }\times Amount \\\\\sf\implies Share_{(Thabo)}= \dfrac{2}{1+2}\times Rs\ 1,500 \\\\\sf\implies Share_{(Thabo)}= \dfrac{2}{3}\times Rs\ 1,500 \\\\\sf\implies \boxed{\pink{\frak{ Share_{(Thabo)}= Rs\ 1,000 }}}[/tex]

A shelf measures 720 mm long.
a) How many centimetres long is the shelf?
b) How many metres long is the shelf?
a) The length of shelf in centimeters is 72 cm
b) The length of shelf in metres is 0.72 m.
What is Unit Conversion?The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.
Given:
A shelf measures 720 mm long.
a) As 1 cm = 10 mm
So, the length of shelf in centimeters
= 720 /10
= 72 cm
b) As 1 m = 1000 mm
So, the length of shelf in meters
= 720 /1000
= 0.72 m

Carmine pain an electrician x dollars per hour for a 5 hour job plus 70 for parts. The total charge was 320 which equation can be used to determine how much do electrician charge per hour
Answer:
5x + 70 = 320
Step-by-step explanation:
We know that Carmine paid an electrician a certain amount per hour, we also know that they worked for 5 hours. Therefore we have 5x.
He also got paid 70 for parts, meaning an extra $70
And we know that we have the total charge and that the main point of this question is to determine how much the electrician was paid per hour.
Therefore :
5x + 70 = 320

The answer to the problem
================================================
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (8-6)/(2-5)
m = (2)/(-3)
m = -2/3
As you can see, we subtract the y coordinates together. We also subtract the x values together in the same order. If the order is mixed up, then you'll get the wrong sign for the final answer.
The slope is equal to rise over run. Think of "rise" as "change in y", which explains the difference in y values. The run is equal to the change in x, which is the difference in x values.
