Option C: 6 is the value of [tex]b(-10)[/tex]
Explanation:
The given expression is [tex]b(x)=|x+4|[/tex]
We need to determine the value of [tex]b(-10)[/tex]
To find the value of [tex]b(-10)[/tex], let us substitute [tex]x=-10[/tex] in the given expression.
Thus, substituting [tex]x=-10[/tex] in the expression, we have,
[tex]b(-10)=|-10+4|[/tex]
Adding the terms, we get,
[tex]b(-10)=|-6|[/tex]
Since, we know the absolute rule that [tex]|-a|=a[/tex] and the simplified expression is of the form [tex]|-a|[/tex] , let us apply the absolute rule in the simplified expression.
Thus, we have,
[tex]b(-10)=6[/tex]
Thus, the value of [tex]b(-10)[/tex] is 6.
Hence, Option C is the correct answer.

________+ 1 1/10=3 1/2
Answer: 12/5 or 2 2/5
Step-by-step explanation:
From the question: ________+ 1 1/10=3 1/2
Let the missing value be x
Convert the improper fraction to proper fraction
1 1/10 = 11/10
3 1/2= 7 /2
Therefore, x + 11/10 = 7/2
Subtract both sides of the equation by 11/10 to get the value of x
x + 11/10 - 11/10 = 7/2 - 11/10
x = 24/10
x = 12/5 or 2 2/5
Answer:
2.4 or 2 2/5
Step-by-step explanation:
1. Creating the Equation
This problem is meant to have you work backwards from the information given. In this case, there is no reason to organize information, as this is not a word problem.
Instead, a simpler approach would be to replace the blank space with the variable x.
Once x replaces the blank space, the equation should appear as shown:
x + 1 1/10 = 3 1/2
2. Solving for x
Now that the equation was created, use the order of operations to solve for x.
Firstly, convert all the mixed numbers into improper fractions to simplify the solving process.
x + 11/10 = 7/2
Next, convert the 7/2 fraction into the same denominator as the 11/10 fraction. To do this, multiply both the numerator and the denominator by 5/5.
x + 11/10 = 7/2
x + 11/10 = 5/5(7/2)
x + 11/10 = 35/10
Finally, subtract the 11/10 fraction from both sides of the equation to find the solution to x.
x + 11/10 = 35/10
x + 11/10 - 11/10 = 35/10 - 11/10
x = 24/10
x = 2 4/10
(Simplify the fraction if needed)
x = 2 2/5
As said earlier, x was meant to represent the final answer.
x + 1 1/10 = 3 1/2
x = 2 2/5
2 2/5 + 1 1/10 = 3 1/2

If the trapezoid below is reflected across the x-axis, what are the coordinates
of B?
A. (4-8)
B.(-4,-8)
C. (-4,8)
D. ( -8,-4)
As you may have intentionally forgotten to add the diagram. The diagram of the trapezoid is attached below.
Answer:
The point B(4, 8) after reflection across x-axis would be B'(4, -8).
B(4, 8) → B'(4, 8)
Step-by-step explanation:
The rule of reflection across the x-axis states that a reflection of a point, let say M(x, y), across the x-axis does not change the value of x-coordinate but changes the sign of the y-coordinate of the point.
In a nutshell,
The point M(x, y) after reflection across x-axis would be M'(x, -y)
M(x, y) → M'(x, -y)
From the diagram attached below, the coordinate of point B is (4, 8).
So, according to the rule of reflection across the x-axis, the coordinates of the image of the point B (4, 8) after the reflection across the x-axis will be B'(4, -8).
i.e.
The point B(4, 8) after reflection across x-axis would be B'(4, -8).
B(4, 8) → B'(4, 8)

What is the density of a 50-gram pyramid with rectangular base 4 x 8 cm and height 10 cm?
The density of the pyramid is calculated by first finding the volume using the formula for a pyramid's volume, and then dividing the mass by this volume, resulting in a density of approximately 0.469 g/cm³.
Explanation:To find the density of a pyramid with a rectangular base, we first need to calculate its volume. The formula for the volume of a pyramid is V = (1/3)Bh where B is the area of the base and h is the height. In this case, the base has dimensions of 4 cm by 8 cm, so its area is 4 cm * 8 cm = 32 cm². The height of the pyramid is given as 10 cm, so the volume can be calculated as V = (1/3)*32 cm²*10 cm = 106.67 cm³.
With the mass of the pyramid given as 50 grams, the density (ρ) can be calculated using the formula ρ = mass/volume. Thus, the density is 50 grams / 106.67 cm³ = 0.469 g/cm³. Therefore, the density of the pyramid is approximately 0.469 g/cm³.

Solve by elimination.. SHOW YOUR WORK. -3x + 2y = 18
-9x - 5y=21
Answer:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
Point Form:
( − 4 , 3 )
Equation Form:
x = − 4 , y = 3
Step-by-step explanation:
Answer:
x = —4, y = 3
Step-by-step explanation:
-3x + 2y = 18 (1)
-9x - 5y =21 (2)
To solve by eliminating, the coefficients of either x or y must be the same in both equation.
Now let us make the coefficient of x in both equation to be the same. To do this, multiply equation (1) by the coefficient of x in equation (2) ie —9, and multiply equation (2) by the coefficient of x in equation (1) ie —3 this is illustrated below :
—9 ( —3x + 2y = 18)
27x — 18y = — 162 (3)
—3 ( —9x — 5y = 21)
27x + 15y = —63 (4)
Now, subtract equation 4 from equation 3
27x — 18y = — 162
— (27x + 15y = —63)
—33y = —99
Divide both side by —33
y = —99/—33
y = 3
Now we substitute the value of y into any of the equation to obtain x. In this case, let use equation 4
27x + 15y = —63
27x + 15(3) = —63
27x + 45 = —63
Collect like terms
27x = —63 —45
27x = —108
Divide both side by 27
x = —108/27
x = —4
Therefore, x = —4, y = 3

11 units
11 StartRoot 2 EndRoot units
22 units
22 StartRoot 2 EndRoot units
Length of the other leg is 22 units
Step-by-step explanation:
Step 1: The length of the other legs can be found using Pythagoras Theorem given hypotenuse = 22√2. Let the sides be x.Hypotenuse² = x² + x²
(22√2)² = 2x²
⇒ x² = 22 × 22 × 2/2 = 22 × 22
∴ x = 22 units

A segment has a midpoint at (2,-7) and an endpoint at (8,-5). What are the coordinates of the other endpoint?
Answer:
(-4,-9)
Step-by-step explanation:
Given a segment AB with endpoints with coordinates
A: [tex](x_A,y_A)[/tex]
B: [tex](x_B,y_B)[/tex]
The coordinates of the midpoint M of the segment AB are given by:
[tex]x_M = x_A + \frac{x_B-x_A}{2}\\y_M = y_A + \frac{y_B-y_A}{2}[/tex] (1)
In this problem, we know that:
- The midpoint of the segment AB has coordinates
[tex]x_M=2\\y_M=-7[/tex]
- One of the endpoint of the segment has coordinates
[tex]x_B=8\\y_B=-5[/tex]
So we can find the coordinates of the other endpoint A by re-arranging eq.(1) above:
[tex]x_A=2x_M-x_B\\y_A=2y_M-y_B[/tex]
And substituting, we find:
[tex]x_A=2(2)-8=-4\\y_A=2(-7)-(-5)=-9[/tex]
So, the coordinates of the other endpoint are (-4,-9).
To find the coordinates of the other endpoint, use the midpoint formula to average the x-coordinates and the y-coordinates of the given point and the midpoint.
Explanation:To find the coordinates of the other endpoint, we can use the midpoint formula. The midpoint formula states that the midpoint of a line segment is the average of the x-coordinates and the average of the y-coordinates of the endpoints. So, we can calculate the x-coordinate of the other endpoint by averaging the x-coordinates of the given point and the midpoint: (8 + 2) / 2 = 5. Similarly, we can calculate the y-coordinate of the other endpoint by averaging the y-coordinates: (-5 + (-7)) / 2 = -6.
Therefore, the coordinates of the other endpoint are (5, -6).

x + y < 8
x + y > 8
x + y ≤ 8
x + y ≥ 8
Answer:
[tex]x + y \leqslant 8[/tex]
Step-by-step explanation:
The key idea here is to identify how to translate the statement, no more than, into inequality.
No more than 8 means less or equal to 8.
If Jess saw x dramas and y comedies at the movie theater, and she went to the theater no more than 8 times,then the inequality that best describes the situation is:
[tex]x + y \leqslant 8[/tex]

Which shows one way to determine the factors of x^3+5x^2-6x-30 by grouping?
[tex]\left(x^{2}-6\right)(x+5)[/tex] are the factors of the expression by grouping
Step-by-step explanation:
[tex]x^{3}+5 x^{2}-6 x-30[/tex]
We have to group the terms as,
[tex]\left(x^{3}+5 x^{2}\right)-(6 x-30)[/tex]
We can take the common factors as,
= [tex]x^{2}(x+5)-6(x+5)[/tex]
So it can be written as,
= [tex]\left(x^{2}-6\right)(x+5)[/tex]
So it was factorized by grouping.

What is Reflection of an object?The reflection of an object refers to creating a mirror image of the object, similar in shape and size, just the coordinates are switched.
When a point is reflected over an axis, the coordinate of the other axis changes to its additive inverse.
The coordinates (x,y) when reflected over x axis change to (x,-y)
The polygon is reflected over x axis
then the coordinate ( x,y) will become (x,-y)
After translation, 5 units down, the coordinate change to
( x, -y-5)

Can anyone help me with this math and explain how you got it if you can? If not just the answer and the number to the question.
The first two steps in determining the solution set of the system of equations, y = x2 – 6x + 12 and y = 2x – 4, algebraically are shown in the table.Which represents the solution(s) of this system of equations? (4, 4) (–4, –12) (4, 4) and (–4, 12) (–4, 4) and (4, 12)
The solution to the system of equations is [tex]\( (4, 4) \)[/tex]. Therefore the correct option is a.
Given equations:
1. [tex]\( y = x^2 - 6x + 12 \)[/tex]
2. [tex]\( y = 2x - 4 \)[/tex]
To find the solution to the system, we'll set the two equations equal to each other because they both equal [tex]\( y \)[/tex]. So:
Step 1:
[tex]\[ x^2 - 6x + 12 = 2x - 4 \][/tex]
Now we will move all terms to one side to set the equation to zero.
Step 2:
[tex]\[ x^2 - 6x + 12 - 2x + 4 = 0 \][/tex]
[tex]\[ x^2 - 8x + 16 = 0 \][/tex]
This is a quadratic equation. To solve for [tex]\( x \)[/tex], we can either factor the quadratic, use the quadratic formula, or complete the square. The equation in Step 2 seems to be a perfect square trinomial.
Step 3:
The equation [tex]\( x^2 - 8x + 16 \)[/tex] factors to [tex]\( (x - 4)^2 = 0 \)[/tex].
Step 4:
Now, we solve for [tex]\( x \)[/tex] by taking the square root of both sides.
[tex]\[ (x - 4)^2 = 0 \][/tex]
[tex]\[ x - 4 = 0 \][/tex]
[tex]\[ x = 4 \][/tex]
Now that we have the value of [tex]\( x \)[/tex], we can substitute it back into either of the original equations to solve for [tex]\( y \)[/tex]. We can use the simpler equation [tex]\( y = 2x - 4 \)[/tex].
Step 5:
[tex]\[ y = 2(4) - 4 \][/tex]
[tex]\[ y = 8 - 4 \][/tex]
[tex]\[ y = 4 \][/tex]
So the solution to the system of equations is [tex]\( (4, 4) \)[/tex]. There is only one solution because the quadratic equation had a repeated root, meaning the lines intersect at exactly one point.

the y intercept, to the nearest hundredth, of the line -9y=7x+8
Answer:
(0, -0.89) or -0.89
Step-by-step explanation:
Step 1: Solve for y by dividing both sides by -9
-9y = 7x + 8
-9y / -9 = (7x + 8) / -9
y = -7/9x - 8/9
Step 2: Identify the y-intercept
y = mx + b
m is slope
b is y-int
y = -7/9x - 8/9
Answer = (0, -0.89) or -0.89
Answer:
-0.89
Step-by-step explanation:
(see attached graphic for reference)
recall that the slope-intercept form of a line looks something likeL
y = mx + b
where m is the slope and b is the y-intercept.
Hence all we need to do is to rearrange our equation so that it looks like the one above.
-9y=7x+8 (divide both sides by -9)
-9y / (-9) = (7x+8) / (-9)
y = (7x+8) / (-9) (use distributive property )
y = [ 7x / (-9) ] + [ 8/(-9) ]
y = (-7/9)x + (-8/9)
comparing this equation with the general equation above,
we can see that the
y-intercept , b
= -8/9
= -0.88888..............
= -0.89 (nearest hundredth)
