For this case we must propose an algebraic expression associated with:
"four times a difference of a number and seven is 12"
So we have to:
Four times a difference of a number and seven is represented as: 
So we have the expression is:
We apply distributive property to the terms within parentheses:
We add 28 to both sides:
We divide between 4 on both sides:
Answer:
Answer:
Step-by-step explanation:
1) 737/7= 105.285714 so 105 pencils per class and 2 pencils left over
2) 342/3= 114 so 114 people
3) 558*7= 3906 so 3,906 marbles in total
4) 835/5 = 167 children per house
5) 156*12= 1872 so 1,872 apples
6) 138*92= 12696p or 126.96 pounds
7) 1276*8= 10208 matches
8) 2736/9= 304 sweets each
You're not being annoying btwww
Just let every x in f(x) be g(x)
it means:
f(g(x))=(2x^2+5)^2+(2x^2+5)+2
=4x^4+20x^2+25+2x^2+5+2
=4x^4+22x^2+32
Answer:
B
Step-by-step explanation:
Let x = every day he rented the kayak
Since the store charges $60 for each day, multiply x by 60 like this: 60x
They also have $25 on top of that; 60x + 25
This all has to equal $325; 60x + 25 = 325
To solve for x, subtract 25 from both sides
60x + 25 = 325
- 25 - 25
60x = 300
Divide both sides by 60
60x/60 = 300/60
x = 5
This means Tobias rented the kayak for 5 days
Answer:
Step-by-step explanation:
Given
Required
Initial expression of f(x) is
From the question; we understand that f(x) was shifted down by 3 units;
This implies that
Also from the question; we understand that this new f(x) is equivalent to g(x);
In other words;
Substitute and
This gives
<em />
Subtract 0.5x to both sides
Rearrange
Multiply both sides by -1
