Given m n, find the value of x and y
Answer:
x=24
y=58
Step-by-step explanation:
5x+20=6x-4
5x-6x=-20-4
-x=-24 /:(-1)
x=24
5×24+20+y-18=180
122+y=180
y=180-122
y=58
Use I = PTR to solve
(time is in years)
I=$252
R=7% find T.
P=$900
The time period in years T = 4 years
The simple interest amount = $252
The rate of interest per year as percentage = 7%
The principal amount = $900
The simple interest I = PTR
Where I is the interest amount
P is the principal Amount
T is the time period involved in years
R is the rate of interest per year as a percent
Substitute the values in the equation
252 = 900 × T × (7 / 100)
252 = 900 × T × 0.07
252 = 63 × T
Move the 63 to other side
T = 252 / 63
T = 4 years
Hence, the time period in years T = 4 years

Write an equation in standard form for the line that passes through the given points
(3,0) and (0, -2)
Equation of a line in the standard form that passes through the points (3, 0) and (0, -2) will be [y = (2/3)x - 2].
As per the question statement, a straight line passes through the points (3, 0) and (0, -2).
We are required to determine the equation of the above mentioned line in it's standard form.
To solve this question, we need to know the formula to write the standard equation of a line passing through two points (x₁, y₁) and (x₂, y₂) which goes as [tex][(y-y_{1})=\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}(x-x_{1})][/tex].
Here, let (x₁, y₁) be (3, 0) and (x₂, y₂) be (0, -2).
Therefore, equation of our concerned line passing through the two points (3, 0) and (0, -2), by substituting [(x₁, y₁) = (3, 0)] and [(x₂, y₂) = (0, -2)] in the above mentioned formula, will be [(y - 0) = {(-2 - 0)/0₂ - 3)}(x - 3)]
Or, [y = {(-2)/(-3)}(x -3)]
Or, [y = (2/3)(x - 3)]
Or, [y = (2/3)x - 2]

Given a rectangle with the following dimensions: Area = 50 units Length = x + 10 units Width = x units Find the value of x.
Step-by-step explanation:
the area of a triangle is
length × width
in our case
(x + 10) × x = 50
x² + 10x = 50
x² + 10x - 50 = 0
the general solution to such a quadratic equation
ax² + bx + c = 0
is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case that is
x = (-10 ± sqrt(10² - 4×1×-50))/(2×1) =
= (-10 ± sqrt(100 + 200))/2 =
= (-10 ± sqrt(300))/2 = (-10 ± sqrt(100×3))/2 =
= -5 ± sqrt(100×3/4) = -5 ± sqrt(25×3) =
= -5 ± 5×sqrt(3)
x1 = -5 + 5×sqrt(3) = 3.660254038...
x2 = -5 - 5×sqrt(3) = -13.66025404...
x2 gives us negative values for length and width. that does not make any sense for actual lengths of objects.

Find the area of ABCD with vertices A(-5,2), B(-3,2), C(-2,-5),
D(-4,-5).
Answer:
14 units²=============================
Given Vertices A(-5,2), B(-3,2), C(-2,-5), D(-4,-5)To find The area of ABCDSolutionWe can observe that:
1. AB and CD are horizontal segments, since both endpoints have same y-coordinates:
A and B have y = 2, C and D have y = - 52. AB and CD are of same length:
AB = - 3 - (-5) = 2,CD = - 2 - (-4) = 2.It means the ABCD is a parallelogram, since two opposite sides are parallel and of same length.
The area of parallelogram is:
A = bh, where b- base length, h - heightWe know the length of the base, it is found above, 2 units.
The height is the difference of y- coordinates:
h = 2 - (-5) = 7The area is:

Find four consecutive even integers such that the least plus twice the greatest equals 264
The four consecutive integers in the question are; 51, 52, 53, 54
What is the Sum of the Integers?Let the four consecutive integers in the question be;
x, x + 1, x + 2 and 2(x + 4)
Now, we are told that the sum of these four consecutive integers is 264. Thus;
x + x + 1 + x + 2 + 2(x + 3) = 264
Expanding the bracket gives;
3x + 3 + 2x + 6 = 264
5x + 9 = 264
5x = 264 - 9
5x = 255
x = 255/5
x = 51
Thus;
Second integer = 51 + 1 = 52
Third integer = 51 + 2 = 53

State the line of reflection
Based on the given figures, the line of reflection will be c. Reflection across x-axis.
How to find the line of reflection?If it looks like the line of reflection is a horizontal line as is the case here, the way to find the line of reflection is by finding the midway point between corresponding points on the graph.
For instance, use the coordinates of D and D' and C and C'.
The coordinates of D and D' are:
D = (-1, 1)
D' = (- 1, -1)
The Midpoint can be found to be:
= ( (x₁ + x₂) / 2, (y₁ + y₂) / 2)
= ( (-1 + (-1)) / 2), ( (1 + (-1)) / 2
= (-1, 0)
The coordinates of C and C' are:
C = (4, 1)
C' = (4, -1)
The Midpoint can be found to be:
= ( (x₁ + x₂) / 2, (y₁ + y₂) / 2)
= ( (4 + 4) / 2), ( (1 - (-1)) / 2
= (4, 0)
The line of reflection is therefore the x-axis because the value of y is 0 and the x = axis is the line that crosses y at 0.

Divide the Fabric yards by the number of costumes:
7 / 2 = 3.5

1-2p=-4p-9 solve equation
Answer: p= -5
Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
carry the one over to the right side and subtract it to get an amount of -10.
then carry the -4p to the left and add it with -2p. which comes out to be 2p
now the equation reads as 2p=-10
continue to divide 2 to get p alone and divide -10 by 2 as well.
now p=-5 because a negative divided by a postive is a negative.
a rectangular tennis court has an area of 528 m^2. If the length is decreased by 1 m and the width is increased by 1 m, the area of the tennis court is increased by 16 m^2. Find the perimeter in metres. thanks
The perimeter of the rectangular tennis court is 96.7 m
How to solve an equationAn equation shows the relationship between two or more numbers and variables.
Let x represent the length and y represent the width. A rectangular tennis court has an area of 528 m², hence:
Area = length * width
528 = xy
y = 528/x
If the length is decreased by 1 m and the width is increased by 1 m, the area of the tennis court is increased by 16 m². Hence:
new area = new length * new width
528 + 16 = (x - 1)(y + 1)
xy + x - y + 1 = 544
x(528/x) + x - 528/x + 1 = 544
528 + x - 528/x + 1 = 544
multiplying through by x:
528x + x² - 528 + x = 544x
x² -15x - 528 = 0
x = 31.67, hence y = 528/31.67 = 16.67
Perimeter = 2(x + y) = 2(31.67 + 16.67)
Perimeter = 96.7 m
The perimeter is 96.7 m

The factored equation y=(x−1)(x−5)(x+7) has zeros (or x-intercepts).
The zeros of the factored form of the equation is x = 1, 5, and -7.
What is Factorization ?
Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form. Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.
We have been given the factored equation as; y=(x−1)(x−5)(x+7) that has zeros (or x-intercepts).
y=(x−1)(x−5)(x+7)
then the roots of the equation;
For (x−1)
x - 1 = 0
x = 1
For (x−5)
x - 5 = 0
x = 5
For (x+ 7)
x + 7 = 0
x = -7

Find the general form of an equation of the line through the point A that satisfies the given condition.
A( -4, 2)
a) parallel to the x-axis.
b) perpendicular to the x-axis.
The general form of equation a) y = 2, b) x = -4.
Here the point A = (-4,2)
a) we have to find the equation parallel to the x-axis
As a line should be parallel to x axis so it must pass from y-axis. As the coordinate of A is (-4, 2) so by this we get y = 2 and x = -4.
But we have to put the value of x as 0 and y = 2 then only we get an equation of a line parallel to x-axis.
So y = 2
which is parallel to x-axis
b) equation of a line perpendicular to the x-axis.
As a line should be perpendicular to x-axis, so line should pass form the x-axis and not with the y-axis. As point A is (-4. 2), so we have to take the value of x = -4 and y = 0. So we get an equation.
x = -4 is the general equation.
Therefore the general equation a) y =2 and b) x =-4.

Answer:
ΔABC ≅ ΔNKW because when ΔABC is translated 9 units right and 5 units down, it results in the other triangle.
Step-by-step explanation:
The triangles are congruent as the measures of their corresponding sides and angles are the same.
To determine the translation of ΔABC to ΔNKW, find the change in the x and y values from one of the points of ΔABC to its corresponding point of ΔNKW.
Point C = (0, 0)Point W = (9, -5)Therefore:
ΔABC ≅ ΔNKW because when ΔABC is translated 9 units right and 5 units down, it results in the other triangle.

By solving equations, we can conclude that there are 30 oatmeals in the jar.
What are equations?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.So, a number of oatmeals are in the jar.
Let, sugar cookies be 'x'.Chocolate chips are '3x'.Oatmeals be '3x + 12'The total number of cookies is 54.
From the equation:
x + 3x + 3x + 12 = 54Now, solve for 'x' as follows:
x + 3x + 3x + 12 = 547x + 12 = 547x = 54 - 127x = 42x = 42/7x = 6Number of oatmeals when "x = 6':
