You start at (8, 9). You move left 5 units. Where do you end?
Answers
Answer: (3,9)
Step-by-step explanation:
Move left so on the x-axis. Up/down is on the y-axis.
Left is negative, right is positive on the x axis.

(3, 9)
Step-by-step explanation:
First, what does it mean to move left 5 units from your starting position?
Second, how does that change were you are at this point?
ok so I start at (8, 9). I move left 5 units. Where do I end?
Since moving to the left changes my x variable, subtract 5 from 8
8 - 5 = 3
so that means my final position is at (3, 9)

Answers
Answer:
12.3246
Step-by-step explanation:
The equation to be solved is [tex]x^{2} -10=4x[/tex]
Rearranging: [tex]x^{2} -4x-12=0[/tex]
The quadratic formula is one way to solve this equation.
[tex]x=\frac{-b+\sqrt{b^{2} -4ac} }{2a}=\frac{12+\sqrt{12^{2}-4*1*4} }{2*1}[/tex]
Note that only the positive variation of the quadratic formula was used. This is because it is the only variation of this formula that produces a positive result for this equation. This is not always true, so it is best to work both versions of the formula for problems like these.
[tex]x=\frac{12+\sqrt{160} }{2} =\frac{12+4\sqrt{10} }{2}=6+2\sqrt{10} =6+6.3246=12.3246[/tex]
If the negative version of the quadratic equation was used, the final (incorrect) answer would be x= -0.3246.
A sequence is defined by g(1) = 3 and g(n) = 2 • g(n-1) for n > 0. Which statement defines the nth term of g?
A. G(n) = 3 + 2(n-1) for n ≥ 1
B. G(n) = 3 + 2n for n ≥ 1
C. G(n) = 3 • 2^n-1 for n ≥ 1
D. G(n) = 3 • 2^n for n ≥ 1
Answers
Answer:
because g(n) = 2.g(n - 1) => this is a geometric progression
=> g(n) = 3.2^(n-1)

What is the total total amount of digits you need to number a book of 1150 pages
Answers
Step-by-step explanation: When numbering the pages of a book, which has 1,150 pages, we need: 9 one-digit numbers (from 1 – 9);90 two-digit numbers (from 10 – 99);900 three-digit numbers (from 100 – 999);151 four-digit numbers (from 1,000 – 1,150).
The total amount of digits you need to number a book of 1150 pages will be 3493 digits.
What is an arithmetic operation?It is described as the process through which we add, subtract, multiply, and divide numerical values. It has the fundamental operators +, -, and.
There are pages for the digits totaling,
Single digits : (1 - 9) = 9 pages
Double digits : (10 - 99) = 90 pages
Triple digits : (100 - 999) = 900 pages
Four digits : (1000 - 1150) = 151 pages
By summing all digit counts such as, one may determine the total number of digits.
= (9 + 180 + 2700 + 604)
= 3493 digits.
Thus, the total amount of digits you need to number a book of 1150 pages will be 3493 digits.

10x47=$4.70

$4.70+$0.20=$4.90
Gap= $3.40

If the expression 4x-3 is equal to 11 for some value of x, then what is the expression 4x-1 equal to for
the same value of x?
(1) -15
(3) 9
(2) 13
(4) -11
Answers
Step by step equation-
4x-3=11
Add three to both the three and the 11 to get the x alone.
4x=14
Divide both sides by 4.
x=3.5
Next, substitute the x in 4x-1 so the equation is now 4(3.5)-1
4 times 3.5 is equal to 14.
14-1=13
