Answer:
Step-by-step explanation:
The line representing Murphy street goes through point (0, 3) and has a slope of 2/1 = 2. Its equation is then ...
y = mx + b
y = 2x +3
The translation vector transforms this equation* by adding -1 to y, and replacing x with x-1.
y = (2(x-1)) +3) -1
y = 2x -2 +3 -1 . . . . eliminate parentheses
y = 2x . . . . . . . . . . . the equation for Nolan street
__
Of course, adding (1, -1) to the point (0, 3) moves it to ...
(1, -1) +(0, 3) = (0+1, -1+3) = (1, 2)
The image of (0, 3) is (1, 2).
_____
* f(x) is translated by (a, b) this way: g(x) = f(x-a) +b. Here, f(x) = 2x+3 is translated to f(x-1)+(-1) = (2(x-1) +3) -1.
Answer:
x < 5
Step-by-step explanation:
Given that:
(x+4 over 2x-1)<0
It can be written as:
x + 4/2x-1 <0
Multiplying both sides by 2x -1
x+ 4 < 2x -1
By simplifying:
Take terms with x on left side and constants on right side:
x - 2x < -1 - 4
- x < -5
"-" sign will be cancelled from both sides
x < 5

Answer:
V≈706.86
Step-by-step explanation:
V=πr2h ( formula for volume of a cylinder)
Answer:
The answer is c and we'll use c to get the actual answers.
A) n + q = 104
B) .05n + .25q = 22 we'll multiply B) by -4
B) -.2n -1q = -88 then we add A)
A) n + q = 104 which equals
.8n = 16
n = 20 nickels
q = 84 quarters
20 nickels = $1
84 quarters = $21
