Evaluate XYZ squared if x = -2, y = 7, and z= -4.
The required value of XYZ squared would be 3136 which is determined by substituting x = -2, y = 7, and z = -4.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
We have to evaluate xyz squared if x = -2, y = 7, and z = -4.
⇒ (xyz)²
Substitute the values of x = -2, y = 7, and z = -4 in the above expression
⇒ [(-2) × (7) × (-4)]²
Apply the multiplication operation and we get
⇒ (56)²
⇒ 3136
Therefore, the obtained value of XYZ squared would be 3136 if x = -2, y = 7, and z = -4.

The graph of linear function is a straight line. A function with the formula y=f(x)=ax+by=f(x)=ax+b is said to be linear.
Although not quite the same, arithmetic progressions resemble linear functions.
If the value nn is a full number, then the expression t(n)=2n-4t(n)=2n4 denotes a series, and the graph of this sequence will have distinct points (as shown below).
The expression f(x)=2x-4f(x)=2x4, where xx is any real number, on the other hand, denotes a function, and this function's line graph will be continuous (as shown below).

According to the following graph, the equations y=x+7 and y=x²+4 will intercept 2 times at the points (-1.3, 5.7) and (2.3, 9.3).
Intercept:
The point where the line or curve crosses the axis of the graph is known as intercept.
That is, if a point crosses the x-axis, then it is known as the x-intercept. Similarly, if a point crosses the y-axis, then it is called as the y-intercept.
Given,
Here we have the equation y=x+7 and y=x²+4.

Which 2 of the following are correct equations of the line passing through (2, -3) with a slope of five?
y+3 = 5 (x-2)
y= 5x -3
y= 5x + 13
y-3= 5 (x+2)
y= 5x -13
Answer:
The two equations that passes through (2, -3) and has a slope of five are:
y + 3 = 5(x - 2) and y = 5x - 13
Step-by-step explanation:
For the first equation, you get y equal to itself. To do that, you need to simplify the right side of the equation. For 5(x - 2), you will distribute the 5 to the x and -2, equalling to 5x - 10. Next, we subtract 3 from both sides to cancel out the 3 on the left side. The equation is now y = 5x - 13. The -13 is the y intercept so we start at the point (0, -13). Since the slope goes up by 5 for every one point it moves to the right, it will eventually reach the point (2, -3). In other words, you add 1 to the x value and 5 to the y value. The points will look like this: it starts at (0, -13) and goes to (1, -8) and goes to (2, -3). The second equation is equivalent to the first equation. Hopefully this helps you out!
Thenegative interval(3) of the functiony=-X²+1 are
We are given the following function
[tex]y=-x^2+1[/tex]We are asked to find the negative interval of this function.
A negative interval means that where the y values of the function are negative.
Let us have a look at the graph of this function.
As you can see,
For x = 0, the interval is positive.
For x = 1 and x = -1 the y value is 0 (we don't consider 0 as either positive or negative that's why 0 is not included in the negative or positive interval)
The y values of the function are negative for
x > 1 and x < -1
Therefore, the negative interval of the function y = x² + 1 is

Describe the transformations to the basic function. Then, write the equation of the function.
The given function is a graph transformation of the absolute value function.
What are Function Transformations?A function transformation "moves," "resizes," or "reflects" the parent function's graph. Function transformations are classified into three types: Translation, Dilation, and Reflection. Only dilation alters the size of the original shape; the other two transformations change the shape's position but not its size.
Step 1: Parent function y = f₁(x) = |x|
Step 2: f₁(x) is reflected (Reflection) about x-axis to form f₂(x) = -f₁(x) = -|x|
Step 3: f₂(x) is moved to left by 5 units(Horizontal translation) to form f₃(x) = f₂(x + 5) = -|x + 5|
Step 4: f₃(x) is moved up 1 unit (Vertical translation) to form f₄(x) = f₃(x) + 1 = -|x + 5| + 1
The equation of the given graph is:
y = |x + 5| +1

2334567Happy Paws charges $19.00 plus $2.50 per hour to keep a dog during the day. Woof Watchers charges$10.00 plus 53.75 per hour. Complete the equation and solve it to find for how many hours the total costof the services is equal. Use the variable h to represent the number of hours.The equation isThe total cost of the services will be equal athours.
Let h be the hours and y the total charge. Then, for Happy Paws, we have
[tex]y=2.50h+19[/tex]and for Woof Watches, we have
[tex]y=3.75h+10[/tex]Then, we need to solve these equations.
Solving by elimination method.
If we multiply by -1 the first equation, we have the equivalent system of equations:
[tex]\begin{gathered} -y=-2.50h-19 \\ y=3.75h+10 \end{gathered}[/tex]If we add both equations, we obtain
[tex]0=(3.75-2.50)h+10-19[/tex]because y-y=0. Then, it yields,
[tex]0=1.25h-9[/tex]If we move -9 to the left hand side as -9, we have
[tex]\begin{gathered} 9=1.25h \\ h=\frac{9}{1.25} \\ h=7.2 \end{gathered}[/tex]Hence, to find the total cost, we must substitute this values into one of the 2 equations. If we choose the first one, we obtain
[tex]\begin{gathered} y=2.50(7.2)+19 \\ y=18+19 \\ y=37 \end{gathered}[/tex]Then, the answers are:
The equation is
[tex]2.50h+19=3.75h+10[/tex]and, the total cost of the services will be equal at 7.2 hours

What is an angle?Two rays, referred to as the angle's sides and vertex, come together to form an angle. Angles created by two rays are located in the plane where the rays are located.
Dihedral angles are formed when two planes intersect. The angle formed by the rays lying perpendicular to the two intersecting curves at their point of intersection can also be used to define an angle between two intersecting curves.
Angle is a term used to describe the size of an angle or of a rotation. This metric represents the proportion of a circular arc's length to radius. In the case of a geometric angle, the arc is centred at the vertex and is bound by the sides.
We know that vertical angles of intersection are equal, so here
⇒ (8w+8) = (9w-5)
⇒ 8w+8 = 9w-5
⇒ 9w - 8w = 8 + 5
⇒ w = 13

3. Is x^5 + x² + x? a polynomial? Explain why or why not.
ANSWER:
A polynomial is an algebraic expression of ordered addition, subtraction, and multiplication made up of variables, constants, and exponents.
Polynomials are made up of finite terms. Each term is an expression that contains one or more of the three elements they are made of variables, constants, or exponents.
In this case, for each term, the variable is x, the constant is 1, and the exponents are 5, 2, and 1, respectively.
This means that we have a sum of monomials, that is, that the expression is a polynomial.

In ΔEFG, is it possible for segment GE to measure 6 units?
According to the triangle inequality theorem, the measure for the third side can be GE = 6 units, because: A. 3 + 5 > 6, 5 + 6 > 3, and 6 + 3 > 5.
What is the Triangle Inequality Theorem?The triangle inequality theorem states that the set of side measurements that will form a triangle will be the set of side lengths whereby the sum of any two sides will be greater than the third side of the triangle.
For example, if a, b, and c are the side lengths of a triangle, then:
a + b > ca + c > bb + c > aThus, we have the given lengths:
FE = 3 units
FG = 5 units
Therefore, the third side length would be GE = 6 units based on the triangle inequality theorem because:
3 + 5 > 6
5 + 6 > 3
6 + 3 > 5
