7. Identify the explicit formula for the sequence given by the recursive formula
Answer: B) f(n) = 30 - 8(n - 1)
Step-by-step explanation:
Explicit formula is of the form: [tex]a_n=a_1+d(n-1)[/tex] where
[tex]a_1[/tex] is the first term d is the difference between consecutive termsGiven: f(1) = 30 --> this represents the first term [tex]a_1[/tex] = 30
f(n - 1) - 8 --> this means the previous term minus 8 thus d = -8
[tex]a_n[/tex] = 30 + (-8)(n - 1)
= 30 - 8(n - 1)
Answer:
B. f(n) = 30 – 8(n – 1)

The quotient of a number and 17 is 118.82.
A. it can be solved with division property of equality.
B. It can be solved with the multiplication property of equality
C. The equation should x/17=118.82
D.x=7
E. X=2020
Answer:
C. The equation should x/17=118.82
Step-by-step explanation:
We know that
Dividend ÷ Divisor = Quotient
Dividend/Divisor = Quotient
From the question, we are told that:
The quotient of a number and 17 is 118.82
Let us represent the unknown number as x = Dividend
17 = Divisor
Quotient = 118.82
Hence,
x / 17 = 118.82
Cross Multiply
x = 17 × 118.82
x = 2019.94
The correct answer = Option C. The equation should x/17=118.82

Darnell thinks that -4 is less than -6 because 4 is smaller than 6, and -4 is closer to 0 than -6 is. Explain why Darnell is incorrect.
Answer:
Darnell is incorrect because negative numbers are different than positive numbers. -4 is greater than -6 because it is closer to 0. Which means that it is closer to the positives. :) The biggest negative number is always going to be less than the smaller negative number. :)
Step-by-step explanation:
Answer:
Darnell is incorrect because she is thinking about positive numbers instead of negative numbers.

What is the domain and range for y=x3 – 4x² + x + 6
Answer:
Domain: set of Real numbers
Range{ set of Real numbers
Step-by-step explanation:
Since this is a cubic function, its domain and range are both the set of Real numbers.
The domain of any polynomial function is the set of Real numbers, And as far as the Range, we decide based on its end-behavior: since this is a polynomial with leading term [tex]x^3[/tex], then it has the property of getting to infinitely large values for increasing values of x, and infinitely negative values for decreasing values of x.

The sum of two numbers is 82. One number is three less than four times the other. Find the two numbers.
Answer:
17 , 65
Step-by-step explanation:
x+ y = 82
y = 4x - 3
=====================
Put the second equation into the first.
x + 4x - 3 = 82
5x = 85
x = 85/5
x = 17
17 + y = 82
x = 82 - 17
x = 65

If UV=5x, VW = 8x - 17, and UW = 11x+11, what is UW
Answer:
UW=165
Step-by-step explanation:
UV + VW =UW
5x + 8x-17= 11x +11
13x - 17 = 11x + 11
Subtract 11x and add 17 to both sides:
2x= 28
Divide 2 both sides:
x=14
Plug in x to the equation of UW:
11 (14) +11
165
Can somebody help me out on this question I would really appreciate it so much . Please and thank you .
Step-by-step explanation:
AB = AC, so mark the two sides with single tick marks.
m∠ACD = 128°, so label the angle 128°.
∠ACB is supplementary to ∠ACD, so:
m∠ACB + m∠ACD = 180°
m∠ACB + 128° = 180°
m∠ACB = 52°
ΔABC is an isosceles triangle, so m∠B = m∠ACB.
m∠B = m∠ACB
m∠B = 52°
Angles of a triangle add up to 180°, so:
m∠A + m∠B + m∠ACB = 180°
m∠A + 52° + 52° = 180°
m∠A = 76°

What is the value of x, when -25(x - 4) = -55(x - 10)?
Answer:
-25(x - 4) = -55(x - 10)
-25x+100= -55x+550
-25x+55x=550-100
30x=450
x=15
Answer:
x= 15
Step-by-step explanation:
Step 1- Distribute into the parenthesis
-25x-(-25)4= -55x-(-55)10
Step 2- Multiply to simplify
-25x+100= -55x+550
Step 3- Add -55x to both sides
-25x+100= -55x+550
+55x +55x
Step 4- Subtract 100 to both sides
30x+100= 550
-100 -100
Step 5- Divide both sides by 30
30x= 450
30 30
x= 15

Step-by-step explanation:
Given: 2q – r = 4p, 2r = q, r = 2p; Prove: q = r
Answer:
q = r
Step-by-step explanation:
Explanation:-
Given 2q – r = 4p ...(i)
2r = q...(ii)
r = 2p ...(iii)
Substitute 2r = q in equation (i)
2(2r) – r = 4p
3 r = 4 p
2 r + r = 4 p
2 r + 2 p = 4 p
2 r = 2 p
q = r
If your exponent on your power 10 is positive, is your number larger or smaller than 10?
Answer:
See below.
Step-by-step explanation:
The number maybe less than 10, equal to 10, or larger than 10.
Examples:
A.
exponent: 1/2
10^(1/2) = sqrt(10) (less than 10)
B.
exponent: 1
10^1 = 10 (equal to 10)
C.
exponent: 2
10^2 = 10 * 10 = 100 (larger than 10)

Answer:
20
Step-by-step explanation
not sure but looks like you need help as fast as possible here my answer the way i thought about is you have 70 degree angle and y looks like a right angle which = 90 degree
x = 180 - 70+90
x = 180 - 160
x = 20
The value of the angle x for the given triangle will be 20°.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
As per the given triangle,
m∠y = 90°
The exterior angle = sum of two interior angles except for the adjacent angle of the exterior angle.
110° = x + y
110° = x + 90°
m∠x = 20°
Hence "The value of the angle x for the given triangle will be 20°".

3(x-5) – 1/2(10x + 10) I don’t understand and I need the answers
Answer:3x-15-5x-5
-2x-20
Step-by-step explanation:
Answer:
-2x-20
Step-by-step explanation:
Expand 3(x-5) : 3x-15
Do not forget there is a subtraction sign in the middle.
Expand 1/2(10x+10) : 5x+5 : 5(x+1)
= 3x - 15 - 5(x+1)
Expand -5(x+1) : -5x-5
= 3x-15 - 5x - 5
Simplify 3x-15-5x-5 by adding like terms: -2x-20
= -2x-20

Answer:
y = 4/3
Step-by-step explanation:
the expression can be written as,
(x^8)^1/3 divided by (x^4)^ 1/3
so by using the rules of powers we can deduce y = 4/3
The rules are,
1. (x^y)^z = X^y*z
2. x^y * x^z = x^ y+z
3. x^y / x^z = x^ y-z
Hence,
8/3 -4/3 = 4/3
