Solve the formula for the specified variable
A=p+prt solve for r
Answer:
Step-by-step explanation:
The first step is to take p on both sides:
[tex]A - p = p + p*r*t - p[/tex]
On the right hand side, cancel p and -p, since [tex]p-p=0[/tex]. The equation will be:
[tex]A - p = p*r*t[/tex]
Then, divide both sides of the equation by p*t:
[tex]\frac{A-p}{p*t} = \frac{p*r*t}{p*t}[/tex]
On the right hand side, p*t can be cancelled:
[tex]\frac{A-p}{p*t} = r[/tex]
Answer:
r=A-p (the line is the bar so this is a-p over pt)
pt
Step-by-step explanation:
P + Prt = A
P r t=A −P isolate the term which contains r
P rt=A−P
divide pt by each side
find the coordinates of Z if Y is the midpoint of XZ , X( -10, 9) , and Y( -4,8)
Answer:
The coordinates of Z are (2,7)
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to
[tex]Y=(\frac{x1+x2}{2} ,\frac{y1+y2}{2})[/tex]
we have
X(-10,9),Y(-4,8)
Let
(x2,y2) ----> the coordinates of Z
substitute the values
[tex](-4,8)=(\frac{-10+x2}{2} ,\frac{9+y2}{2})[/tex]
Solve for x2
[tex]-4=(-10+x2)/2\\-8=-10+x2\\x2=10-8\\x2=2[/tex]
Solve for y2
[tex]8=(9+y2)/2\\16=9+y2\\y2=16-9\\y2=7[/tex]
therefore
The coordinates of Z are (2,7)
Answer: The required co-ordinates of Z are (2, 7).
Step-by-step explanation: Given that Y is the midpoint of XZ and the co-ordinates of X are (-10, 9) and the of Y are (-4, 8).
We are to find the co-ordinates of Z.
Let (a, b) represents the co-ordinates of the point Z.
We know that
the co-ordinates of the midpoint of a line segment with endpoints (x, y) and (z, w) are given by
[tex]\left(\dfrac{x+z}{2},\dfrac{y+w}{2}\right).[/tex]
So, according to the given information, we have
[tex]\left(\dfrac{-10+a}{2},\dfrac{9+b}{2}\right)=(-4,8)\\\\\\\Rightarrow \dfrac{-10+a}{2}=-4\\\\\Rightarrow -10+a=-8\\\\\Rightarrow a=-8+10\\\\\Rightarrow a=2[/tex]
and
[tex]\dfrac{9+b}{2}=8\\\\\Rightarrow 9+b=16\\\\\Rightarrow b=16-9\\\\\Rightarrow b=7.[/tex]
Thus, the required co-ordinates of Z are (2, 7).

[2+(-4)]+5-[(-11)x(-2)]-(-7)
Answer: -12
Step-by-step explanation:
[2+(-4)] becomes (2-4), or -2, and 5-[(-11)x(-2)]-(-7) becomes 5-22+7, so the entire thing is -2+5-22+7, so it is -12.
The given expression [2+(-4)]+5-[(-11)x(-2)]-(-7) simplifies to -12.
To simplify the given expression, we follow the order of operations (PEMDAS/BODMAS):
Step 1: Evaluate the innermost parentheses:
[2 + (-4)] + 5 - [(-11) x (-2)] - (-7)
[2 - 4] + 5 - [(-11) x (-2)] - (-7)
Step 2: Complete the operations inside the brackets:
[-2] + 5 - [22] - (-7)
Step 3: Simplify the subtraction and negation:
-2 + 5 - 22 + 7
Step 4: Perform addition and subtraction from left to right:
(5 - 2) - 22 + 7
3 - 22 + 7
Step 5: Continue performing addition and subtraction:
-19 + 7
Step 6: Final result:
-12
The expression simplifies to -12.

Find the distance between the points (a, 0) and (0, b).
Answer:
d = sqrt( a^2 + b^2)
Step-by-step explanation:
Formula
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Givens
x1 = a
x2 = 0
y1 = 0
y2 = b
Solution
d = sqrt( (0 - a)^2 + (b - 0)^2 )
d = sqrt( a^2 + b^2)
which is another way of writing the Pythagorean theorem.
To find the distance between points (a, 0) and (0, b), use the distance formula which results in √(a² + b²). This involves calculating the square root of the sum of the squares of the coordinates.
Therefore, the final distance is √(a² + b²).
Finding the Distance Between Two Points
To find the distance between two points (a, 0) and (0, b), we use the distance formula:
Distance formula: d = √((x2 - x1)² + (y2 - y1)²)
Let's denote the points as:
Point 1: (a, 0)
Point 2: (0, b)
Applying the coordinates to the distance formula, we get:
d = √((0 - a)² + (b - 0)²)
Simplifying inside the square root:
d = √(a² + b²)
So, the distance between the points (a, 0) and (0, b) is √(a²+ b²).
Lucinda has a pocketful of dimes and quarters with a value of $6.20. The number of dimes is 18 more than 3 times the number of quarters. How many dimes and how many quarters does Lucinda have?
Answer:
The number of dimes is 42 and the number of quarters is 8
Step-by-step explanation:
Let
x -----> the number of dimes
y -----> the number of quarters
Remember that
1 dime=$0.10
1 quarter=$0.25
we know that
0.10x+0.25y=6.20 -----> equation A
x=3y+18 ----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (42,8)
see the attached figure
therefore
The number of dimes is 42 and the number of quarters is 8
There are 42 dimes and 8 quarters
Further explanationThe two-variable linear equation is a linear equation that has 2 variables and the exponent is one
Can be stated in the form:

In this equation system there are coefficients and variables whose solutions can use:
1. substitution 2. elimination 3. graph 4. mix
We can state the problem in the form of algebraic equations
Lucinda has a pocketful of dimes and quarters with a value of $ 6.20
we translate this sentence into Algebraic expressions:
dime = D = $ 0.10
quarter = Q = $ 0.25
Then the equation becomes:
0.1D + 0.25Q = 6.20The number of dimes is 18 more than 3 times the number of quarters
we translate this sentence into Algebraic expressions:
D = 18 + Q
D - 3Q = 18
We solve the two equations with substitution and elimination
1. elimination
0.1D + 0.25Q = 6.20 x 10
D - 3Q = 18 x 1
------------------------------------
D + 2Q = 62
D - 3Q = 18
----------------------------------- -
5.5Q = 44
Q = 8
2. substitution
D - 3Q = 18
D - 3.8 = 18
D - 24 = 18
D = 42

I am joyous to assist you anytime.
Answer:
The slope of the line is 1 and it passes through the point (1,4).
Step-by-step explanation:
If a line passes through a points [tex](x_1,y_1)[/tex] with slope m, then the point slope form of the line is
[tex]y-y_1=m(x-x_1)[/tex] .... (1)
The given equation of line is
[tex]y-4=(x-1)[/tex] .... (2)
We need to find the slope and the coordinates of a point on the given line.
On comparing (1) and (2) we get
[tex]m=1[/tex]
[tex]x_1=1[/tex]
[tex]y_1=4[/tex]
Therefore, the slope of the line is 1 and it passes through the point (1,4).
