Given m n, find the value of x and y
Answer:
x=24
y=58
Step-by-step explanation:
5x+20=6x-4

-x=-24 /:(-1)
x=24
5×24+20+y-18=180
122+y=180
y=180-122
y=58
Question: Is it x = 6 or x = 58/9?
Problem: 3(x-5)+2(3x-1)=41
Solve X.
Answer:
58/9 = x
Step-by-step explanation:
3(x-5) + 2(3x-1) = 41
Expand:
(3x-15) + (6x-2) = 41
Simplify:
9x-17 = 41
9x = 58
x = 58/9

use the graph to determine wither the function is even, oddPlease check photo
EXPLANATION:
Given;
We are given a graph of a function.
Required;
We are required to determine from the graph if the function is even, odd or neither even nor odd.
Solution:
To determine this from a graph, we should note that a function which is symmetrical with the y-axis is an even function. The graph which is symmetrical with the origin after a 180 degree rotation is an odd function.
Observe that if this graph is flipped from left to right (across the y-axis), it would not retain its original shape.
However, if the graph is rotated 180 degrees about the origin, it would retain its original shape.
Therefore, the graph depicted is an odd function

The equation in slope-intercept form of the line passing through the given points is, y = (-1/2)x + 1
A table containing values of x and y is given:
x y
-2 2
0 1
2 0
4 -1
So the points on the line are:
(-2,2), (0,1), (2,0) and (4,-1)
The equation in slope-intercept form of a line is,
y = mx + c,
where m is the slope of the line and c, the y-intercept of the line.
So we need to find the slope and the y-intercept of the line from the given table values.
Let (x₁, y₁) = (-2,2) and (x₂, y₂) = (0,1).
Then slope of the line, m = (y₂-y₁)/(x₂-x₁)
= (1-2)/(0- -2)
= -1/2
The y-intercept of a line is the y-co-ordinate of the point which intersect the y-axis. I.e., it is the y-co-ordinate of the point at which x = 0.
From the table, when x = 0, y = 1.
Hence the y-intercept, c = 1.
So finally, the equation in slope-intercept form of the line is,
y = (-1/2)x + 1

Help I tried solving this a billion times!!!!!!!!!!
3(5-x)-2(5+x)=3(x+1) solve for x
Primarily use the Distributive Property to solve this equation.
3(5 - x) - 2(5 + x) = 3(x + 1)
Distribute the outer terms.
3(5) + 3(-x) - 2(5) - 2(x) = 3(x) + 3(1)
15 - 3x - 10 - 2x = 3x + 3
-3x - 2x + 15 - 10 = 3x + 3
-5x + 5 = 3x + 3
Now, isolate all x terms.
-5x + 5x + 5 = 3x + 5x + 3
5 = 8x + 3
5 - 3 = 8x + 3 - 3
2 = 8x
2/8 = 8x/8

The cookie jar contains three types of coolcies: chocolate chip, sugar and oatmeal. There are 3 times as many chocolate chip as sugar cookies, and 12 more oatmeal than chocolate chip. If there are 54 cookies in the jar, how many oatmeal cookies are there?
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':
3x + 123(6) + 1218 + 1230Therefore, by solving equations, we can conclude that there are 30 oatmeals in the jar.

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.

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 value of x in the given figure is 10.
What is Pythagoras' Theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a fundamental relationship between a right triangle's three sides in Euclidean geometry.According to this statement, the areas of the squares on the other two sides add to the area of the square whose side is the hypotenuse.In the given triangle,
∠ADC = ∠BDC = 90°
Hence the triangles ΔACD and ΔBCD are right-angle triangles. Thus we can apply Pythagoras' theorem in both triangles.
So in ΔACD,
CB² = BD² + DC²
And in ΔBCD,
CA² = AD²+ DC²
But, CA = 15 and CB = x + 5
So, (x + 5)² = BD² + DC²
15² = AD² + DC²
⇒225 = AD² + DC²
Here, BD = AD as given in the figure
Replacing BD with AD in the first equation we get,
(x + 5)² = AD² + DC²
Now, equate the values of AD² + DC² to obtain the value of x,
(x + 5)² = 225
⇒ x² + 25 + 10x = 225
⇒ x² + 10x - 200 = 0
⇒ x² + 20x - 10x - 200 = 0
⇒x(x + 20) - 10(x + 20) = 0
⇒(x + 20)(x - 10) = 0
Thus x = -20, 10
Hence the value of x is 10.

Solve the quadratic equation x2 + 3x = 40 using the quadratic formula.
A)
x = –8, x = 5
B)
x = 5, x = 8
C)
x = –5, x = 8
D)
x = –8, x = –5
After solving the quadratic equation x² + 3x = 40 using the quadratic formula, (A) x = –8, x = 5
We can solve this quadratic formula by following a few steps.
The given equation is,
x² + 3x =40
Let's subtract 40 from both sides,
x² + 3x - 40 =40 - 40
Or, x² + 3x - 40 = 0
Now, we have to find a suitable pair of factors of -40 which is capable to generate +3 ( coefficient of x ).
The required pair is 8 and -5, and ( 8 - 5 ) = 3
[ -40 = 8 × -5 ]
Therefore, x² + 3x - 40 = 0
Or, x² + ( 8 - 5 )x - 40 = 0
Or, x² + 8x - 5x - 40 = 0
Or, x ( x + 8 ) - 5 ( x + 8 ) = 0 [ taking x and 5 as common ]
Or, ( x + 8 ) ( x - 5 ) = 0 [ taking ( x + 8 ) as common ]
If the multiplication or product of two or more terms is zero, then we can write each term as zero.
Hence we can write,( x + 8 ) = 0
Or, x = -8 ( by subtracting 8 from both sides )
Again we can write,( x - 5 ) = 0
Or, x = 5 ( by adding +5 with both sides )
Now, we can conclude that x = -8 and 5.
