What is the meaning of the coordinate?A pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes.it can be represented by (x,y) that is the x-value and y-value.
Therefore the value of x and y at point (0,0) is 0 and 0.
The value of x and y at point (0,2) is 0 and 2.
The value of x and y at point (4,4) is 4 and 4.
The value of x and y at point (4,0) is 4 and 0.
Therefore the coordinate of the given figure is,

2(z + –16) = 22 z=_______
First distribute the 2 through the parenthses.
So we get 2z + -32 = 22.
Since adding a negative is the same as subtracting,
we can change the problem to read 2z - 32 = 22.
Solving from here, add 32 to both sides to get 2z = 54.
Now divide both sides by 2 to get z = 27.

Find the equation of the line with points (3,3) in y=mx+b where it is perpendicular to equation 5x+5-4y=0
Answer:
y = -[tex]\frac{4}{5}[/tex] x + [tex]\frac{27}{5}[/tex] or
5y = -4x + 27
Step-by-step explanation:
To find the equation of a line with points (3,3) and is perpendicular to 5x+5-4y=0
we will follow the steps below:
First find write the equation: 5x+5-4y=0 in standard form y= mx + c and find the slope
5x+5-4y=0
4y = 5x + 5
divide through by 4
4y /4= 5x/4 + 5/4
y = [tex]\frac{5}{4}[/tex] x + [tex]\frac{5}{4}[/tex]
comparing the above with y = mx + c
m= [tex]\frac{5}{4}[/tex]
since the equations are perpendicular.
To find the new slope
[tex]m_{1}[/tex][tex]m_{2}[/tex] = -1
[tex]\frac{5}{4}[/tex] [tex]m_{2}[/tex] = -1
multiply both-side of the equation by [tex]\frac{4}{5}[/tex]
[tex]\frac{4}{5}[/tex]× [tex]\frac{5}{4}[/tex] [tex]m_{2}[/tex] = -1 × [tex]\frac{4}{5}[/tex]
[tex]m_{2}[/tex] = -[tex]\frac{4}{5}[/tex]
The slope of our new equation is -[tex]\frac{4}{5}[/tex]
The points are (3,3)
We can now go ahead and form our new equation
y - [tex]y_{1}[/tex] = m ( x - [tex]x_{1}[/tex])
y - 3 = -[tex]\frac{4}{5}[/tex] ( x - 3)
y - 3 = -[tex]\frac{4}{5}[/tex] x + [tex]\frac{12}{5}[/tex]
y = -[tex]\frac{4}{5}[/tex] x + 3 + [tex]\frac{12}{5}[/tex]
y = -[tex]\frac{4}{5}[/tex] x + [tex]\frac{27}{5}[/tex]
5y = -4x + 27

a. Graphing
b. Substitution
c. Elimination
d. None, they are all exact.
Graphing is the least accurate method for solving systems of equations, and it may only give an approximate answer. Hence, option A is the right choice.
What is the system of equations?A system of equations is made up of two or more equations that are solved at the same time.
What are the different ways of solving systems of equations?There are three ways to solve a system of equations:
Graphing: All equations are graphed and the point of intersections are the solutions for the system of equations.Substitution: One variable is isolated in one equation, and its value is substituted in the other equation to solve the system of equations.Elimination: Operations are done on all equations to eliminate one variable and then solve for the system of equations.How to solve the question?In the question, we are asked which method for solving systems of equations is the least accurate and may only give an approximate answer.
We have discussed all methods above.
Of these methods, when solving manually, as the degree of the equation gets bigger and bigger, the graphing of equations will become difficult, and thus the graphing method will be the least accurate.
Thus, graphing is the least accurate method for solving systems of equations, and it may only give an approximate answer. Hence, option A is the right choice.

Explanation:
The rectangular prism (aka rectangular block) has dimensions 2, 4 and 3. You can say they are the length width and height. The volume is 2*4*3 = 24 cubic cm.
The trapezoid's volume is found by multiplying the area of the trapezoidal face by the depth of 3 cm. Let's find the area of the trapezoid first
A = area of trapezoid
A = height*(base1+base2)/2
A = 2*(4+2)/2
A = 6
Then we multiply this with the depth of 3 cm to get 6*3 = 18 cubic cm
Lastly, we subtract the two volumes
difference in volume = (rectangular block) - (trapezoidal block)
difference in volume = 24 - 18
difference in volume = 6 cubic cm
----------
An alternative is to find the volume of each triangular piece on the left and right sides. Then add up those portions to get the answer. In a way, you can think of those triangular wedges as empty space.

Step-by-step explanation:
A discriminant value of zero means there is exactly one x-intercept. The graph below has that characteristic.
_____
Comment on discriminant
discriminant > 0, two (2) x-intercepts (first 2 graphs)
discriminant < 0, no (0) x-intercepts (third graph)
A quadratic function with a discriminant of 0 only touches the x-axis, hence it is represented by the fourth graph.
What is the discriminant of a quadratic equation and how does it influence the solutions?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The discriminant is:
[tex]\Delta = b^2 - 4ac[/tex]
The solutions are as follows:
If [tex]\mathbf{\Delta > 0}[/tex], it has 2 real solutions, hence it crosses the x-axis twice.If [tex]\mathbf{\Delta = 0}[/tex], it has 1 repeated solution, hence it touches the x-axis.If [tex]\mathbf{\Delta < 0}[/tex], it has 2 complex solutions, hence it does not touch the x-axis.In this problem, the fourth graph touches the x-axis, hence it is the answer to this question.

Answer:
0.894
Step-by-step explanation:
Data provided in the question
BC length = 17.89 unit
DC length = 16 unit.
Now, we have to compute the angle y with the help of the cosine function;
Cosine defines the ratio between the right angle adjacent side and the hypotenuse
[tex]\cos = \frac{Adjacent side}{Hpotenuse}[/tex]
As per the triangle BDC;
Hypotenuse = BC =17.89 unit
And, the Adjacent side = 16 units
So;
[tex]\cos y =\frac{16}{17.89} =0.894354388[/tex]
[tex]y =\cos^{-1} (0.894354388) = 26.57^{\circ} (nearest\ to\ hundredths\ place)[/tex]
Now, determine the value of angle x
In right angle ΔABC;
As we know that
The three angles sum is 180 degrees
So,
[tex]\angle A + \angle B +\angle C =180^{\circ} ....(1)[/tex]
According to the given figure
[tex]\angle B=90^{\circ}, \angle A =x^{\circ}[/tex]
and
[tex]\angle C =y=26.57^{\circ}[/tex]
Now Substitute these in (1) for solving the angle x;
[tex]x^{\circ}+90^{\circ}+y^{\circ} =180^{\circ}[/tex]
or
[tex]x^{\circ}+90^{\circ}+26.57^{\circ} =180^{\circ}[/tex]
or
[tex]x^{\circ}+116.57^{\circ} =180^{\circ}[/tex]
[tex]x^{\circ}=180^{\circ} - 116.57^{\circ}=63.43^{\circ}[/tex]
Finally we have to determine the value of sin x;
Hence,
The value of [tex]\sin 63.43 =0.89438856[/tex]

sin x = 0.894
