Answer:
(3,6)
Step-by-step explanation:
We can substitute y for x+3 in the second equation
4x + x + 3 = 18
5x = 15
x=3
Plug x back into the equation
y = 3 + 3
y = 6
Answer:
B (3 ; 6)
Step-by-step explanation:
y = x + 3
4x + y = 18
4x + (x + 3) = 18
5x = 18 - 3
5x = 15
x = 3
y = x + 3
y = 3 + 3
y = 6

i.e
Speed = (Change in distance) / (Change in time)
Since the graph is a straight line, we can consider any interval to calculate the speed as for a Linear graph the change remains the same.
From the graph we can see that at 1 hr the distance covered is 105 miles and at 2 hr the distance covered is 175 miles.
Change in Distance = 175 – 105 = 70 miles
Change in time = 2 – 1 = 1 hour
So, the speed is = 70 mile/1 hour = 70 miles per hour.
So option B gives the correct answer

X=-6 is your answer
Final answer:
The solution to the equation 5(x - 8 ) =7 (x - 4) is x = 6.
Explanation:
To solve the equation 5(x - 8 ) =7 (x - 4), you first need to distribute the numbers outside the parentheses to the terms inside. It leads to : 5*x - 40 = 7*x - 28. To find the value of x, first combine like terms and then isolate x on one side of the equation. By doing so, the equation yields 40 - 28 = 7*x - 5*x, simplifies to 12 = 2x, and thus x = 6.
