Answer:
D
Step-by-step explanation:
General Equation: y = mx + b
You need two pieces of data to solve this.
When x = 1, y = 8
8 = 1x + b
When x = -1, y = 3
3 = - x + b
==================
8 = x + b
3 = -x + b If we add we get b so let's add.
11 =2b Divide by 2
11/2 = b
==================
y = mx + b
y = mx + 11/2 Now we can solve for m
3 = -m + 11/2 Subtract 11/2
3 - 11/2 = - m
- 2 1/2 = -m multiply by - 1
2 1/2 = m
m = 5/2
The answer is D
Answer:
16
Step-by-step explanation:
a, 10
Group of 10 23s gives us 230. This is so because of you arrange 23 in groups, you would need to arrange it in 10 places, to get 230.
b, 6
Group of 6 23s gives 138. Again, like stated above, arranging 23 in 6 places ends up giving us a total of 138.
Adding both together, we have
10 + 6 = 16.
This means our answer is 16. And this is rightly so. Dividing 368 by 23 gives us 16 exactly. So, 16 is the answer.
I do not understand could you make the equation more clearer??
A. x=50. If you are charged $2 when you go over 200 miles and he drove 250 then he drove 50 miles over so the answer is 50.
