Answer: y = 3
Step-by-step explanation: You're given x, find y.
-2(-3) + 3y = 12 (substitute in for x)6 + 3y = 12 (multiply)3y = 9 (divide both sides by 3)3 = yThe solution is P ( -3 , 2 )
The value of y from the equation -2x + 3y = 12 is y = 2
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
-2x + 3y = 12 be equation (1)
The point on the line is P = P ( -3 , y )
On simplifying the equation , we get
Substituting the value of x = -3 in the equation , we get
-2x + 3y = 12
-2 ( -3 ) + 3y = 12
6 + 3y = 12
Subtracting 6 on both sides of the equation , we get
3y = 6
Divide by 3 on both sides of the equation , we get
y = 2
Therefore , the value of y is 2
Hence , the point P ( -3 , 2 ) lies on the equation -2x + 3y = 12

Given that 1 inch = 2.54 cm, how many centimeters are there in 7 feet? Answers may be written using decimals form and should be rounded to the nearest hundredth when necessary
Answer:
There are 213.36 centimeters in 7 feet.
Step-by-step explanation:
It is given that:
1 inch = 2.54 cm
We have to find centimeters in 7 feet.
We will convert feet to inches.
1 feet = 12 inches
7 feet = 12*7 = 84 inches
Now,
1 inch = 2.54 cm
84 inches = 2.54 * 84
84 inches = 213.36 cm
Therefore,
There are 213.36 centimeters in 7 feet.

please it do in 6 min i need help with this one please The following points are from a dilation. If
B(0 , 5 ) and B'(x, 2 0 ), what is x?
Answer:
The value of x = 0
Step-by-step explanation:
Given
B(0, 5)B'(x, 20)To determine
The value of x = ?
If we closely observe the value of the y-coordinate of the image B'(x, 20), we can see that the y-coordinate of the image B' is 4 times the y-coordinate of the original point (0, 5).
i.e. y → 5×4 =20
It means the coordinates of the image B'(x, 20) can be determined by dilating the original point (0, 5) by a scale factor of 4.
Thus, the x-coordinate of B'(x, 20) can also be obtained by multiplying the x-coordinate of B(0, 5) by 4.
i.e. x → 4×0 = 0
Thus, the rule of dilation is:
P(x, y) = P'(4x, 4y)
Hence,
B(0, 5) → B'(4(0), 4(5)) → B'(0, 20)
Thus,
The value of x = 0 ∵ 0×4 = 0

During a hockey game, the puck slid 27meters across the ice rink as it was chased by a hockey player skating at 9.5 meters per second. The puck slid that distance in 1.5seconds at a steady speed. What was the puck's speed
Answer:
Speed of Puck is 18 m/s
Step-by-step explanation:
Mathematically;
speed = distance/ time
The puck traveled a distance of 27 m in 1.5 seconds
The speed of the puck is thus;
27/1.5 = 18 m/s

David drove 236 miles in 4 hours. On average how fast did he drive, in miles per hour?
David drove 236 miles in 4 hours. On average he drives 59 miles per hour.
A key idea in mathematics is time speed and distance. Questions like circular motion, boats, and streams, mobility in a straight line, clocks, races, etc. frequently involve the concepts of time and distance. You can get a clear understanding of the Relationship Between Time Speed and Distance, Units, Conversions, etc. from this article. Find Formula for Time and Distance, Solved Examples that thoroughly demonstrate the subject.
How quickly or slowly an object move is all about the concept of speed in motion. Distance divided by time is the definition of speed. When a specific piece of information is known, the three variables of speed, distance, and time are given to solve for one of the three variables.
[tex]speed = \frac{distance}{time}[/tex]
According to the question, David drove 236 miles in = 4 hours
so, he can drive = [tex]\frac{236}{4}[/tex] miles in 1 hour
= 59 miles.

In a sale, normal prices are reduced by 35% The normal price of a bed is $1200 Work out the sale price of the bed.
Answer:
£780
Step-by-step explanation:
as its a decrease
we subtract 35 from 100 to get 65
we then divide 65 by 100
to get 0.65
then we do 0.65*1200
to get the answer of $780
A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%. The sale price of the bed is $780.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the normal price of a bed is $1200. Therefore, the sale price of the bed is,
Sale Price = $1200 × (100% - 35%)

Which of the following belongs to the set of Whole numbers?
0
-5
1╱3
Answer:
0
Step-by-step explanation:
Answer:
0 is the only option that belongs to the set of Whole numbers.
Step-by-step explanation:
We know that whole numbers:
are general counting numbers 0, 1, 2, 3, 4, 5, 6, … and so on.contains natural numbers that start from 1 onwards.contains positive integers along with 0.In general, the set of whole numbers is:
W = {0, 1, 2, 3, ...}
Thus, the set of whole numbers DOES NOT include negative integers and fractions.
Therefore, 0 is the only option that belongs to the set of Whole numbers.

1.) Substitute x, y, and general form using the formulas:Formula for x: [tex]x=d=6[/tex]Formula for y: [tex]y=k=-6[/tex]Formula for general form y: [tex]y=\frac{a}{x-d}+k=y=\frac{3}{x-6}+(-6)[/tex]Note:
- When doing problems like this, it's best to list out each formula and do the drag down method, and replace methods rather than doing it the entire mathematical way, as doing it that way takes a long time and it's more confusing than it should be.
Equation at the end of Step 1:
[tex]y=\frac{3}{x-6}+(-6)[/tex]2.) Simplify the d and k forms:[tex]y=\frac{3}{x-6}+(-6)=y=\frac{3}{x-6}-6[/tex]Note:
- The x(d) stays the same since the 6 was positive and we plugged it in making it negative, so it doesn't need to be changed. (Another way to know if you need to change it is if the original [tex](d)[/tex] or [tex](k)[/tex] when plugged in, you had to put them in parenthesis then most likely it needs to be changed.
- The y(k) changes from [tex]+(-6)[/tex] to [tex]-6[/tex] because when a [tex](+)[/tex] and [tex](-)[/tex] are next to each other, the rule is [tex]+<-[/tex]. The Minus always wins in this type of problem situation.
So the answer is c, [tex]\bold{y=\frac{3}{x-6}-6}[/tex].

15. In a parallelogram ABCD, AB = 7.2 cm and the perpendicular from C on AB is 4.5 cm find its area.
Answer:
32.4 cm²
Step-by-step explanation:
Given the parallelogram ABCD ; with AB = 7.2 cm
Perpendicular from C on AB is the height of the parallelogram = 4.5 cm
Using the relation fir the area of a parallelogram :
Area of a parallelogram = base * height
Area of a parallelogram = 7.2 cm * 4.5cm
Area of parallelogram = 32.40cm²
Hence, Area of parallelogram is 32.4 cm²
Isabel's family decided to get rid of their cable TV. Originally they were paying $84.00 for the TV, internet and phone, but now they're paying $57.12. What was the percent the bill decreased by?
Answer:
32%
Step-byentrepreneurstion:
The first step is to calculate the decrease
= $84 - $57.12
= $26.88
Therefore the decrease can be calculated as follows
= 26.88/84 ×100
= 0.32×100
= 32%
Hence the bill decreased by 32%
