Which of the following is the graph of 2x - 3y = 6?
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 measures of the angles of a triangle are shown in the figure below. Solve for x.
(6x+3)°
27°
Answer:
x = 10
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.
The ratio of boys to girls in the sixth grade is 3:5. If there are 20 more girls than boys, how many total students are in the sixth grade?
Answer:
80
Step-by-step explanation:
.375, .525, .25 difference. 20/.25 =80
There are 80 students in the sixth grade.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
Thus, a = px, b = qx
We have been given that ratio of boys to girls in the sixth grade is 3:5. If there are 20 more girls than boys, then
Now we need to do as;
b = 20 + g
3x = 20 + 5x
x = 10
Now The students are 8p
8 x 10 = 80
Hence, there are 80 student.

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.

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.
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
