Answer:
The solution set is { } or ∅ ⇒ empty set
Step-by-step explanation:
∵ 2x + 10 < 10
→ Subtract 10 from the two sides of the inequality
∵ 2x + 10 - 10 < 10 - 10
∴ 2x < 0
→ Divide both sides by 2
∴ [tex]\frac{2x}{2}[/tex] < [tex]\frac{0}{2}[/tex]
∴ x < 0
∴ The solutions are all the negative numbers
∵ x ∈ N
∵ N is the set of Natural numbers
→ The natural numbers start at 1 and include all positive whole numbers
∴ N = {1, 2, 3, 4, 5, ..............}
∵ N does not contain any negative numbers
∴ The solution set is an empty set ⇒ ∅
∴ The solution set is { } or ∅

what is the parallel slope intercept form pls help?
Answers
If the line is parallel to the one given, their slopes are the same, so we need to find the y-intercept, then we can determine the slope-intercept form parallel to the given line.
[tex]-1 = 4(4) + b\\\\-1 = 16 + b\\\\-17 = b[/tex]
Now that we have the y-intercept, we can create the equation.
[tex]y = 4x - 17[/tex]
We can prove this by graphing both lines, like so.

Henry runs up 10 flights of stairs.
Then, he runs down 10 flights of stairs.
Does this situation represent additive
Inverses? Explain.
Answers
Answer:
Yes, it does
Step-by-step explanation:
When we add a number to its additive inverse, the resulting value is zero
The first case is running up 10 flights which we consider positive
then he runs down 10 flights of stairs; this we can consider as - 10
So adding this together, we have -10 + 10 to give zero
What this mean is that we have added a number to its additive inverse

Answers
A triangles angles add up to 180 degrees, and along with that the triangles are directly corresponding or are the same as each other meaning the angles are mirrored.
With that in mind we subtract the angles we have from 180 to find the missing angle.
180-70-30
180-100
80
D=80 degrees
Answer:
∠ D = 80°
Step-by-step explanation:
Δ BCA and Δ DCE are congruent ( SAS postulate )
Thus corresponding angles are congruent, thus
∠ D = ∠ B
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles in Δ ABC from 180° to find ∠ B
∠ B = 180° - (30 + 70)° = 180° - 100° = 80°, then
∠ D = 80°

Answer:
The value of x will be:
[tex]x=-5[/tex]Step-by-step explanation:
Given the equation
[tex]4-2(x+7)=3(x+5)[/tex]
Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.
[tex]4-2x-14=3x+15[/tex]
simplifying the equation by subtracting 14 from the L.H.S
[tex]-10-2x=3x+15[/tex]
Subtracting 15 from both sides
[tex]-10-2x-15=3x+15-15[/tex]
[tex]-25-2x=3x[/tex]
combining the like terms
[tex]-25=3x+2x[/tex]
[tex]-25=5x[/tex]
dividing both sides of the equation by 5
[tex]\frac{-25}{5}\:=\:\frac{5x}{5}[/tex]
[tex]-5=x[/tex]
Therefore, the value of x will be:
[tex]x=-5[/tex]Given that n^2/3 = 8 and n> 0

Answer:
16[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the rule of exponents/ radicals
[tex]a^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{a^{m} }[/tex] , then
[tex]n^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{n^2}[/tex] , then
[tex]\sqrt[3]{n^2}[/tex] = 8 ( cube both sides )
n² = 8³ ( take the square root of both sides )
n = [tex]\sqrt{8^3}[/tex]
= [tex]\sqrt{512}[/tex]

A tree is currently 10 feet tall and grows 2 feet per year. Show your work for full credit.
a. Model this scenario with an arithmetic sequence in explicit form. (2)
b. Rewrite the explicit form of the sequence using function notation. (2)
c. How tall will the tree be in 15 years? (1)
Answers
Answer:
(a) An = 2n +8
(b) F(n) = 10 + (n-1)2
(c) 38ft tall
Step-by-step explanation:
The tree is currently 10 feet long and grown 2 feet per year.
The arithmetic sequence is
10 , 12, 14 , 16 , 18 ..............
a( initial value) = 10 , d (common difference) = 2
Explicit forms
(a) An = a +(n-1)d
An = 10 + (n-1)2
= 10 + 2n -2
An = 2n +8
(b) F(n) = 10 + (n-1)2
(c) Height of the tree after 15 years
F(15) = 10 + (15-1)2
= 10 + 28
= 38ft
So the tree will be 38ft tall after 15 years.

Laqueta has three times as many quarters as Pablo if they each spend $.50 Laqueta will have five times as many quarters as Pablo how many quarters do Laqueta and Pablo have now?
Answers
Answer:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = 12
Step-by-step explanation:
Given that:
Laqueta has three times as many quarters as Pablo.
They both spend $0.50.
After that Laqueta will have 5 times as many quarters as Pablo.
To find:
Number of quarters with Laqueta and Pablo now?
Solution:
Let number of quarters with Laqueta = [tex]x[/tex]
Let number of quarters with Pablo = [tex]y[/tex]
As per given statement:
[tex]x=3y ..... (1)[/tex]
In $0.50, there are 2 quarters:
After spending $0.50, number of quarters left with both of them:
Number of quarters left with Laqueta = [tex]x[/tex] - 2 = [tex]3y-2[/tex]
Money left with Pablo = [tex]y[/tex] - 2
As per given statement:
[tex]3y-2 = 5(y-2)\\\Rightarrow 3y-2 = 5y-10\\\Rightarrow 2y = 8\\\Rightarrow y = 4[/tex]
Therefore, the answer is:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = [tex]3 \times 4[/tex] = 12
