Answer:
The Slope of this line = 4 2 = 2. The line is steeper, and so the Slope is larger.
Step-by-step explanation:
Interpreting the slope of a regression line. The slope is interpreted in algebra as rise over run. If, for example, the slope is 2, you can write this as 2/1 and say that as you move along the line, as the value of the X variable increases by 1, the value of the Y variable increases by 2
3- 3x - 36×36 =
3 - 3x - 1296 =
3 - 1296 -3x=
-1293 - 3x
Answer:
<h3>
10, 12, 14</h3>
Step-by-step explanation:
Consecutive even integers increase by 2.
x ← an integer
2x ← an even integer (the smallest)
2x+2 ← next even integer consecutive to 2x (the middle one)
2x+2+2=2x+4 ← the last even integer consecutive to 2x+2 (the largest)
2(2x+2) ← twice the middle number
2x+2(2x+2) ← the sum of the smallest number and twice the middle
2x+4+20 ← 20 more than the largest number
2x + 2(2x + 2) = 2x + 4 + 20
2x + 4x + 4 = 2x + 24
-4 -4
6x = 2x + 20
-2x -2x
4x = 20
÷2 ÷2
2x = 10
2x+2 = 10+2 = 12
2x+4 = 10+4 = 14
The first one is the bottom right multiply 7.50*h or the hours to find the cost
and the second one is bottom left you start at 0 and advance 0 the multiply or add 67*2=134 then 67*5=335 and then 67*9=603 so you have your numbers 0,134,335,603

Trying to factor as a Difference of Squares:
2.1 Factoring: 9x-1
Theory : A difference of two perfect squares, A - B can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A - AB + BA - B2 =
A
- AB + AB - B2 =
A - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 9 is the square of 3
Check : 1 is the square of 1
Check : x is the square of x1
Factorization is : (3x + 1) • (3x - 1)
Final result :
(3x + 1) • (3x - 1)
