Answer:
Step 1: Remove parentheses by multiplying factors.
= (x * x) + (1 * x) + (2 * x) + (2 * 1)
Step 2: Combine like terms by adding coefficients.
(x * x) = x2
(1 * x) = 1x
(2* x) = 2x
Step 3: Combine the constants.
(2 * 1) = 2
Step 4: Therefore, Simplifying Algebraic Expression is solved as
= x2 + 3x + 2.
Answer:
Step-by-step explanation:
(200+30+5)(40+9)
40*200 = 8000
40*30= 1200
40*5=200
9*200= 1800
9*30=270
9*5=45
8000+1200+200+1800+270+45 =11515
Logically, he would owe 14 less each week
Let x = # of weeks passed
Algebraic Expression: 141 - 14x =
Week 1: 141 - 14 = 127
Week 2: 141 - 14(2) = 113
Week 3: 141 - 14(3) = 99
etc.....
Hope this helps
Answer:
X=51/7, Y= -36/7
Step-by-step explanation:
X/3 + 2y/3 = -1 equ 1
X - y/3 = 9 equ 2
eliminate X/3.
X/3 + 2y/3 = -1..... x 1 ( co-efficient of X in equ2 )
X - y/3 = 9 ...... x 1/3 ( co-efficient of X in equ1 )
X/3 + 2y/3 = - 1 equ 3
-
X/3 - y/9 = 3 equ 4
0 + 7y/9 = -4
y = -36/7
( input the value of y into equ 4 )
X/3 -y/9 = 3
X/3 - (-36/7)/9 = 3
X/3 + 36/63 = 3
X/3 = 3 - 36/63
X/3 = 153/63
63X = 459
X = 459/63
X = 51/7.
(6,-7)
This is because if the midpoint to one endpoint goes right 1 and up 5, then the other endpoint will be left 1 and down 5
