Answer:
slope=m=4/9
(x',y')=(5,14)
(x",y")=(-4,y)
we have
m=(y"-y')/(x"-x')
4/9=(-4-5)/(y-14)
4y-56=-81
4y=-81+56
y=-25/4
Answer: y = 10
Step-by-step explanation:
The slope of a line is the rise/run, so if you want to find the slope of a line between two points, you can take the change in y between the two points and divide it by the change in x.
The change in y would be (y2 - y1), where y2 is the y position of the second point and y1 is the y position of the first.
In a similar manner, to find the change in x, we can use (x2 - x1), where x2 is the x position of the second point and x1 is the x position of the first.
Now that we have the change in x and the change in y, we can make an equation to find the slope (which is change in y / change in x):
m = (y2 - y1) / (x2 - x1)
Now we can assign the points:
Point 1 is (5, 14)
Point 2 is (-4, y)
(Note: You could flip which point is which, and it wouldn't change the final answer, I'm just assigning these so you know where the x and y values are coming from when I plug the values into the equation)
Now that we have both points, we can plug the values into the equation:
m = (y2 - y1) / (x2 - x1)
m = (y - 14) / (-4 - 5)
m = (y - 14) / (-9)
There's one piece of information we haven't used yet, which will help us solve for the value of y. What we need to use is the slope (which is given to us as 4/9).
Plugging in the value of the slope will let us get y:
m = (y - 14) / (-9)
4/9 = (y - 14) / (-9)
-4 = (y - 14)
(Note: We're multiplying both sides by -9, don't forget about the negative sign)
-4 = y - 14
y = -4 + 14
y = 10

tips:
the format for coordinates is (x,y)
the horizontal line is the x axis, so you plot which number of x it lands on, like how A is on the second mark on the x axis.
The vertical line is the y axis, so you plot which number of y it lands onn like how A is on the first mark

what is this 59 divided 535
Answer:
9.07 [Rounded]
Step-by-step explanation:
535 divided by 59 is 9.07, which I rounded.
The value of the division 535 ÷ 59 is 9 with a remainder of 4 and the decimal form can be expressed as 9.067.
To find the value of division 535 ÷ 59, we can perform a long division.
To perform the calculation, we can use long division:
59 ) 535 ( 9
- 531
______
4
Divide the first digit of the dividend (5) by the divisor (59). Since 5 is less than 59, we bring down the next digit, making it 53.
Divide 53 by 59. The result is 0, as 53 is less than 59.
Bring down the next digit, making it 535.
Divide 535 by 59. The result is 9, as 59 can go into 535 nine times.
Multiply 9 by 59, which equals 531.
Subtract 531 from 535, which gives us a remainder of 4.
Therefore, the value of the division 535 ÷ 59 is 9 with a remainder of 4.
In decimal form, the division can be expressed as 9.067, indicating that 59 goes into 535 nine times with a remainder of 4.

Solve tree he system of equations by the substitution method.
12x + 3y =8
-4x = y + 8
Answer:
8x + 2y
Step-by-step explanation:
12x + 3y = 8 you need to transfer the no. 8 to left since it's positive, it will be negative once you tranfer that and the result is this 8x + 3y -8 =0. Then do it again on the second given, -4x = y + 8.
Tranfer the y variable to left, y is positive then it will be a negative. No need to transfer the no. 8. Then the result would be -4x - y + 8=0
To this solve this, wrote it like this:
12x + 3y –8
-4x - y + 8
——————
8x + 2y

At a bakery, each pecan braid has 30 more milligrams
of sodium than each chocolate pastry. If 3 pecan
braids and 4 chocolate pastries have a total of 1840
milligrams of sodium, how many milligrams of
sodium does a pecan braid have?
Answer:
1840 minus 90
1750 divided by 7
Each chocolate pastry has 250 milligrams of sodium
Each pecan braid has 280 milligrams of sodium.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
/ Division operation: Divides left-hand operand by right-hand operand
For example 12/2 = 6
Given that each pecan braid has 30 more milligrams of sodium than each chocolate pastry
If 3 pecan braids and 4 chocolate pastries have a total of 1840 milligrams of sodium.
So, the number of milligrams of sodium present in chocolate pastry as
⇒ 1840 - 90
⇒ 1750
1750 milligrams of sodium are present in chocolate pastry.
Now, the number of milligrams of sodium present in chocolate pastry as
⇒ 1750/7
1750 divided by 7
Each chocolate pastry has 250 milligrams of sodium.
So, each pecan braid has 280 milligrams of sodium.

What is division?One type of operation in mathematics is division. We divide the expressions or numbers into the same number of components during this operation.
Given, Brady rented a car for two days at $25 a day plus $0.15 per mile.
His total bill is $102.50.
We divide the 102.50 by 25.
That means, 102.50 / 25
= 4 is quotient and 2.50 is remainder.
Now we divide 2.50 by 0.15
That means, 2.50 / 0.15
= 16.67 miles
Therefore, 16.67 miles, Brady drove.

A sample of a radioactive isotope had an initial mass of 540 mg in
the year 2009 and decays exponentially over time. A measurement
in the year 2011 found that the sample's mass had decayed to 300
mg. What would be the expected mass of the sample in the year
2021, to the nearest whole number?
Answer:
16 mg
Step-by-step explanation:
[tex]N_0[/tex] = Initial mass of sample = 540 mg
t = Time taken = 2 years
[tex]t_{1/2}[/tex] = Half life of isotope
N = Final mass of sample = 300 mg
Radioactive decay is given by
[tex]N=N_0e^{-\dfrac{\ln 2}{t_{1/2}}t}\\\Rightarrow \ln\dfrac{N}{N_0}=-\dfrac{\ln 2}{t_{1/2}}t\\\Rightarrow t_{1/2}=-\dfrac{\ln2}{\ln\dfrac{N}{N_0}}t\\\Rightarrow t_{1/2}=-\dfrac{\ln2}{\ln\dfrac{300}{540}}2\\\Rightarrow t_{1/2}=2.358\ \text{years}[/tex]
In 2021 the number of years passed from 2009 would be 12 years
[tex]N=N_0e^{-\dfrac{\ln 2}{t_{1/2}}t}\\\Rightarrow N=540e^{-\dfrac{\ln 2}{2.358}12}\\\Rightarrow N=15.86\approx 16\ \text{mg}[/tex]
The expected mass of the sample in the year 2021 would be 16 mg.
