For each sequence, find the first 4 terms and the 10th term.
a) 3n + 4
b) 4n-5
Answer:
see explanation
Step-by-step explanation:
To find the first 4 terms substitute n = 1, 2, 3, 4 into the formula, that is
(a)
a₁ = 3(1) + 4 = 3 + 4 = 7
a₂ = 3(2) + 4 = 6 + 4 = 10
a₃ = 3(3) + 4 = 9 + 4 = 13
a₄ = 3(4) + 4 = 12 + 4 = 16
Similarly substitute n = 10 for tenth term
a₁₀ = 3(10) + 4 = 30 + 4 = 34
(b)
a₁ = 4(1) - 5 = 4 - 5 = - 1
a₂ = 4(2) - 5 = 8 - 5 = 3
a₃ = 4(3) - 5 = 12 - 5 = 7
a₄ = 4(4) - 5 = 16 - 5 = 11, and
a₁₀ = 4(10) - 5 = 40 - 5 = 35
-hx + 4 = 2x- 1 solve this equation for x.
Answer:
x=-5/(-h-2)
Step-by-step explanation:
-hx+4=2x-1
-hx=2x-5
-hx-2x=-5
x(-h-2)=-5
x=-5/(-h-2)
Let me know if this helps!
The equation; -hx + 4 = 2x- 1 when solved for x is; x = 5/(2 +h)
Change of subject of formulaThe given equation is;
-hx + 4 = 2x- 1By collecting like terms; we have;
2x + hx = 4 + 1x(2 +h) = 5x = 5/(2+h)Read more on change of subject;

Answer:
Rhombus and angle 1 = 35
Step-by-step explanation:
The parallelogram has the same marking on each of its sides, indicating that all the sides are equal in length. It is, therefore, a rhombus.
It is given that one of the angles measures 110 degrees. The other angle is 70 degrees (because 180 - 110 = 70). Since it is bisected by a line, divide the angle by 2 (70/2). You get 35 degrees. Therefore, the measure of angle 1 is 35 degrees.

Solve 2(x - 5) = 3(x + 7)
Answer:
x = -31
Step-by-step explanation:
2(x-5) = 3(x+7) 1. Use distributive property
2x - 10 = 3x + 21 2. Add 10 on both sides
2x = 3x + 31 3. Subtract 3x on both sides
-x = 31 4. Divide by -1
x = -31
What is a and b pls answer ASAP I need it !!! Plsss
Answer:
The value of a = 5.
the value of b = 6.
Step-by-step explanation:
Given the points on the line
(6, 10)(a, 8)(4, b)(2, 2)Given that all of the points are on the same line and the line represents a linear function.
Thus, the slope between any two points must be the same.
First, determine the slope between (6, 10) and (2, 2)
(x₁, y₁) = (6, 10)
(x₂, y₂) = (2, 2)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [2 - 10] / [2 - 6]
= -8 / -4
= 2
Thus, the slope of the line = m = 2
Determine the value 'a'
(x₁, y₁) = (6, 10)
(x₂, y₂) = (a, 8)
Using the slope formula to determine the value of 'a'
Slope = [y₂ - y₁] / [x₂ - x₁]
As the slope between two points is 2.
now substitute slope = 2, (x₁, y₁) = (6, 10) and (x₂, y₂) = (a, 8) in the slope formula
Slope = [y₂ - y₁] / [x₂ - x₁]
2 = [8 - 10] / [a - 6]
2(a - 6) = 8 - 10
2a - 12 = -2
2a = -2 + 12
2a = 10
divide both sides by 2
a = 5
Therefore, the value of a = 5.
Determine the value 'b'
(x₁, y₁) = (2, 2)
(x₂, y₂) = (4, b)
Using the slope formula to determine the value of 'b'
Slope = [y₂ - y₁] / [x₂ - x₁]
As the slope between two points is 2.
now substitute slope = 2, (x₁, y₁) = (2, 2) and (x₂, y₂) = (4, b) in the slope formula
Slope = [y₂ - y₁] / [x₂ - x₁]
2 = [b - 2] / [4 - 2]
2(4 - 2) = b - 2
8 - 4 =b - 2
4 = b - 2
b = 6
Therefore, the value of b = 6

A popular Web site reached 7.5 million users during the week of March 7, 2011. This number represents a 33 percent increase from the week before. How many users did the Web site have the week before?
Answer:
5.7 million
Step-by-step explanation:
Let the number of users be x
x + 33% of x = 7.5 million
x + 0.33x = 7.5 million
1.33x = 7.5
x = 7.5/1.33
x = 5.7 million
