Answer:
1.) Multiply the number of pounds by 4 to find total cost.
2.) 280 miles
3.) Multiply 40
4.) Multiply 12 each time: 56*12 = 672
5.) This is the same question as in picture 4
Hope this helps!
The first one YES and the last one NO!
Answer:
-12
Step-by-step explanation:
Since m1 = 10x + 4 and m2 = 5x - 4 then we can write it as:
10x+4=5x-4
Combine the like terms:
10x-5x=-4-4
5x=-8
Divide both sides by 5
5x= -8/5
x=-8/5
Now substitute the value of x in 5x-4
= 5(-8/5) - 4
= -8-4
= -12
Thus m2 = -12....
You would know if it is a linear function if it is a line.
The parent function of a linear equation is y = mx + b
If you can find the m which equals slope and the b which is the y-intercept then it is a linear equation.
You would know that it is decreasing by the slope of the equation or by looking at the line on a graph.
If a line is increasing it would go left to right in the positive direction. But in your line, the line is going from right to left which means that it is decreasing. Once you look at a four quadrant graph you would understand that there are negatives and positives.
To find it on a equation, your slope would have to be a negative slope to be decreasing.
