A car travels at an average speed of 48 miles per hour. how long does it take to travel 204 miles?It takes it 4.25 hours
Answer:
Option (B)
Step-by-step explanation:
There are two lines on the graph representing the system of equations.
First line passes through two points (-3, 1) and (-2, 3).
Slope of the line = 
= 
m = 2
Equation of the line passing through (x', y') and slope = m is,
y - y' = m(x - x')
Equation of the line passing through (-3, 1) and slope = 2 will be,
y - 1 = 2(x + 3)
y = 2x + 7 ----------(1)
Second line passes through (0, 1) and (-1, 4) and y-intercept 'b' of the line is 1.
Let the equation of this line is,
y = mx + b
Slope 'm' = 
= 
= -3
Here 'b' = 1
Therefore, equation of the line will be,
y = -3x + 1 ---------(2)
From equation (1) and (2),
2x + 7 = -3x + 1
5x = -6
x = 
x = 
From equation (1),
y = 2x + 7
y = 
= 
= 
= 
Therefore, exact solution of the system of equations is
.
Option (B) will be the answer.
Answer:
Step-by-step explanation:
<u>Given </u>
- f(x) = x + 4 and
- g(x) = x + 7
<u>Find (g - f)(x):</u>
- (g – f)(x) =
- g(x) - f(x) =
- x + 7 - x - 4 =
- 3
Correct choice is A
F(x) is most likely the f(f(x)x) where f(x) is g(x))f)) and composition can be 69 + 46 which is the total of 137
Answer: 48.95
Step-by-step explanation:
so first I would add together the cost of the shirt and hat
31.59 +19.46 = 51. 05
then I would take away the 51.05 ( the total ) from $100
100 - 51.05 = $48.95
So she would get $48.95 for change
