Answer:
the second equatin
2x+(-6)=14 that give x=10 and the other 2x=14+6 gives x= 10 so this pair is equal
The slope is 2 and the equation of the line is y = mx+b with m =2
Then the equation becomes: y = 2x+b. How to calculate b?
Since this line passes through the point (-3 , 4), we replace x with -3 and y=4
4= 2.(-3) + b
4 = - 6 + b
and b= 10. The final equation is : y = 2x + 10 (answer a)
Answer:
slope = -2
Step-by-step explanation:
Slope formula: 
Given points:
(3 -4) = (x1, y1)
(-2, 6) = (x2, y2)
To find the slope, input the given points into the slope formula:
Solve:
6 - (-4) = 6 + 4 = 10
-2 -3 = -5
Simplify:
The slope is -2.
Answer:
7.2
Step-by-step explanation:
1. Natalie needed 40 minutes to get to school. In hours 40 minutes is 40/60= 2/3 hour (because there are 60 minutes in an hour). so her speed is 14.4/(2/3)= 14.4*3/2= 21.6 mph.
2. Britany needed 40+20= 60 min. 60 min= 1 hour. so she needed 1 hour her speed is 14,4/1= 14.4mph
3. The difference 21.6-14.4=7.2 is the answer .
