Write the equation of the graph in slope-intercept form (y=mx+b).
Write the equation without spaces:
Answers
Answer:
y = mx + b is the slope intercept form of writing the equation of a straight line. In the equation 'y = mx + b', 'b' is the point, where the line intersects the 'y axis' and 'm' denotes the slope of the line. The slope or gradient of a line describes how steep a line is. It can have either a positive or a negative value. When a standard form of a linear equation is of the form Ax + By = C, where 'x' and 'y' and 'C' are variables and 'A', 'B' are constants, the slope-intercept form is the most preferred way of expressing a straight line due to its simplicity, as it is very easy to find the slope and the 'y intercept' from the given equation.
Meaning of y = mx + b
y = mx + b is the slope-intercept form of a staight line. In the equation y = mx + b for a straight line, m is called the slope of the line and b is the y-intercept of a line. y = mx+b, where
y ⇒ how far up or down is the line,
x ⇒ how far along is the line,
b ⇒ the value of y when x = 0 and
m ⇒ how steep the line is.
This is determined by m = (difference in y coordinates)/ (difference in x coordinates). Note that difference in y coordinates is indicated as rise or fall and difference in x coordinates is indicated as run.

The temperature in Doha, Qatar on 1 June is 40°C. Over
the next two days this temperature increases by 10%
followed by a decrease of 10%. Find the temperature in
Doha on 3 June.
Answers
Answer:
39.6°C
Step-by-step explanation:
10% of 40°C is 40 × 10/100
=4
temp on 2 June = 40+4 = 44°C
now 10% of 44°C is 44 × 10/100
=4.4
temp on 3 June = 44 - 4.4 = 39.6°C

Which of the following is the graph of 2x - 3y = 6?
Answers
Answer:
Option B (second graph)
Step-by-step explanation:
Given the linear equation in standard form, 2x - 3y = 6:
It's easier to figure out the corresponding graph by transforming the equation into its slope-intercept form, y = mx + b:
2x - 3y = 6
2x - 2x - 3y = 6 - 2x
-3y = -2x + 6
Divide both sides by -3:
[tex]\frac{-3y}{-3} = \frac{-2x+6}{-3}[/tex]
y = 2/3x - 2
Now that we have the slope-intercept form, it's easier to tell that Graph B represents the given equation because:
The graph's y-intercept occurs at (0, -2).The slope, m = 2/3, is positive. If you use the "Rise over run" technique, you'll see that Graph B rises by 2 units, and runs by 3 units.Therefore, the correct answer is Graph B.

The equation showing the variation of the temperature would be y=(23x) + 68.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that A chef preheats an oven. It starts at room temperature, 68°F, and heats up to 23°F per minute.
The equation will be written as:-
y = 23x + 68
Here x is the time of preheating.
Therefore, the equation showing the variation of the temperature would be y=(23x) + 68.

Step-by-step explanation:
1. The sum of all angle measures in any triangle is equal to 180 degrees.
This means that 90 + 6x + 3 + 27 = 1802. (Solving)
Step 1: Combine like terms.
[tex](6x)+(90+3+27)=180[/tex] [tex]6x + 120 = 180[/tex]Step 2: Subtract 120 from both sides.
[tex]6x + 120 - 120 = 180 - 120[/tex] [tex]6x = 60[/tex]Step 3: Divide both sides by 6.
[tex]\frac{6x}{6}=\frac{60}{6}[/tex] [tex]x = 10[/tex]Therefore, x = 10.
