Answer:
7
Step-by-step explanation:
Consider the absolute value of the difference , that is
| - 5 - 2 | = | - 7 | = 7
or
| 2 - (- 5) | = | 2 + 5 | = | 7 | = 7
Answer:
7
Step-by-step explanation:
Difference is - sign so the equation is: 2- -5 which is 7. Or
think a number line, -5 is 5 spots to 0, then two more spots to 2 so 5+2=7
True or false: f(x) is a function
False because 5 is associated with two values.
To be a function, the domain can only map to one range value, but in this case, 5 is mapped to two values, 1 and 3.

Answer:
Sally is currently 4 years old.
Step-by-step explanation:
Kaden is 18 years older than Sally now. In 5 years, Kaden will be 3 times as old as Sally. How old is Sally now?
Let Kaden's current age be [tex]k[/tex] and Sally's current age be [tex]s[/tex]. We can write the following algebraic equation using the fact that Kaden is currently 18 years older than Sally:
[tex]k=s+18[/tex]
Next, we will use the fact that in 5 years, Kaden will be 3 times as old as Sally. If Kaden and Sally's current ages are [tex]k[/tex] and [tex]s[/tex] respectively, then their ages in 5 years will be [tex]k+5[/tex] and [tex]s+5[/tex] respectively. Therefore, we have:
[tex]k+5=3(s+5)[/tex]
We have two equations with two variables. To solve for either variable, we need to create an equation with only one variable. Therefore, let's substitute the first equation into the second:
[tex](s+18)+5=3(s+5)[/tex]
Distribute and combine like terms:
[tex]s+18+5=3s+15,\\s+23=3s+15[/tex]
Subtract [tex]s[/tex] from both sides, then subtract 15 from both sides:
[tex]8=2s[/tex]
Divide both sides by 2:
[tex]s=\frac{8}{2}=\boxed{4}[/tex]
Therefore, Sally is currently 4 years old.
Answer:
Sally is 4 years old now.
Step-by-step explanation:
Let Sally's age = x
Kaden's age = x + 18
In 5 years, they are both 5 years older than now.
Sally will be x + 5
Kaden will be x + 18 + 5 = x + 23
"In 5 years, Kaden will be 3 times as old as Sally."
x + 23 = 3(x + 5)
x + 23 = 3x + 15
-2x = -8
x = 4
Answer: Sally is 4 years old now.
What is the value of x?
Answer:
x = 54.6 m
Step-by-step explanation:
Δ MAB and Δ MNP are similar, then corresponding sides are in proportion, that is
[tex]\frac{MA}{MN}[/tex] = [tex]\frac{MB}{MP}[/tex] , substitute values
[tex]\frac{80.5-35}{80.5}[/tex] = [tex]\frac{x}{96.6}[/tex]
[tex]\frac{45.5}{80.5}[/tex] = [tex]\frac{x}{96.6}[/tex] ( cross- multiply )
80.5x = 4395.3 ( divide both sides by 80.5 )

1. A rectangular pyramid is intersected by a plane to create the frustum shown. If the height of the original pyramid is 14 m, what is the volume of the frustum?
10 m
4 m
8 m
6 m
12m
The volume of the frustum that is shown in the diagram is: C. 256 m³.
What is the Volume of Frustum?The volume of frustum = Volume of the bigger rectangular pyramid - Volume of smaller rectangular pyramid.
Find the volume of the original (bigger) rectangular pyramid:
Volume of rectangular pyramid = 1/3(lwh) = 1/3(12 × 6 × 14)
Volume of rectangular pyramid = 336 m³
Find the volume of the smaller (the top that was removed) rectangular pyramid:
Volume of rectangular pyramid = 1/3(lwh) = 1/3(10 × 4 × 6)
Volume of rectangular pyramid = 80 m³
The volume of frustum = Volume of the bigger rectangular pyramid - Volume of smaller rectangular pyramid = 336 - 80 = 256 m³.
Thus, the volume of the frustum that is shown in the diagram is: C. 256 m³.

(b) The force, F, between two objects is inversely proportional to the square of the distance, d, between
them.
The distance between two objects is increased by 20%.
Calculate the percentage reduction in the force between the objects.
Answer:
F is reduced by 31%
Step-by-step explanation:
F = 1/(d²)
now, we increase the distance by 20% (multiply by 1.2).
F new = 1/(1.2×d)² = 1/(1.44×d²) = (1/1.44) × (1/(d²)) =
= 1/1.44 × old F = 0.69 × old F
100 - 69 = 31%
An angle measures 75.2° more than the measure of its complementary angle. What is the measure of each angle?
Answer:
x = complement
x + 5.2 = first angle (5.2 more than complement)
measure of two complementary angles add up to 90.
x + x+ 5.2 = 90
2x = 84.8
x = 42.4
other angle = x + 5.2 = 42.4 + 5.2 = 47.6

Does (3, 3) make the equation y = 5x true?
Answer:
y = 5x
In the coordinate (3, 3), the first number is the x value and the second number is the y value.
So, does 3 = 5(3).
The answer is no, so this coordinate does not make the equation true.
Let me know if this helps!
Answer: No, the given point does not make the equation true.
===========================================================
Explanation:
There are three different ways to approach this.
One way is to plug x = 3 into the equation to find that
y = 5x
y = 5*3
y = 15
But that doesn't match up with y = 3 from the point (3,3). So we see that (3,3) is not a solution to y = 5x.
------
Or another method we could do is plug x = 3 and y = 3 to find a contradiction
y = 5x
3 = 5*3
3 = 15
The contradiction being that 3 on the left side doesn't match with 15 on the right side. The false equation at the end means y = 5x is false for (x,y) = (3,3), and therefore this point is not a solution to y = 5x.
------
The third method involves graphing the line y = 5x. You can see that (3,3) is not on the line, which visually confirms the results of the previous two sections. So for a point to be a solution, it must be on the line.

(f/g)(x) = Quantity three x plus two divided by three x minus five. ; domain {x|x ≠ five over three }
(f/g)(x) = Quantity three x minus five divided by three x plus two. ; domain {x|x ≠ five over three }
(f/g)(x) = Quantity three x plus two divided by three x minus five. ; domain {x|x ≠ - two over three }
Answer:
f(x) / g(x) = (3x+2)/ (3x+5) x ≠-5/3
Step-by-step explanation:
f(x) = 3x + 2
g(x) = 3x - 5
f(x) / g(x) = (3x+2)/ (3x+5)
The denominator cannot equal zero
3x+5 ≠0
3x≠-5
x ≠-5/3

C. The left end goes up; the right end goes down.
о
D. Both ends go down.
Answer:
D. Both ends go down.
Step-by-step explanation:
f(x) = -2(x-17)^4
As x goes to -∞
f(-∞) = -2(-∞)^4 = -2 (∞) = -∞
As x goes to ∞
f(∞) = -2(∞)^4 = -2 (∞) = -∞
Both ends go to -∞, or go down

passes through (−3, 7) and is parallel to y = 4x − 1.
Answer:
Equation of the line is y = 4x + 19
Step-by-step explanation:
slope, m = 4
[tex]y = mx + c[/tex]
consider (-3, 7):
[tex]7 = (4 \times - 3) + c \\ 7 = - 12 + c \\ c = 19[/tex]
equation:
[tex]y = 4x + 19[/tex]
Answer:
y = 4x + 19
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 4x - 1 ← is in slope- intercept form
with slope m = 4
Parallel lines have equal slopes, then
y = 4x + c ← is the partial equation
To find c substitute (- 3, 7) into the partial equation
7 = - 12 + c ⇒ c = 7 + 12 = 19
y = 4x + 19 ← equation of parallel line

Find the area and perimeter of the shaded region below. Give your answer as a completely simplified exact value in terms of pi.
Answer:
23.73pi (rounded to the nearest hundredth)
Step-by-step explanation:
You can find the radius of the half-circle by looking at the triangle. You then calculate the area of a circle with that radius and divide the area by 2. Area of full circle=113.1
113.1/2=56.55. You must now calculate the area of the triangle, (6*6)/2. This gives you 18. Add your areas together, 56.55+18=74.55. Now divide your answer by pi. Then you put it as an equation of 74.55/pi = 23.73pi.
