A) 2x-7=13
2x=20
x=10
B) 3x+4=25
3x=21
x=7
Answer:
p=-1
Step-by-step explanation:
y-y1=m(x-x1)
-7-p=-6(-2+3)
-7-p=-6
-p=1
p=-1
Answer: i believe its 8
Step-by-step explanation:
i say 8 because 3x4 is 12 and so if bertha orignally had 4 and was given 4 she would have 8 and if su had 12 and gave away four she would also have 8
Answer:
s = -2400t + 17400
Step-by-step explanation:
Let's say t is the x value on a coordinate plane, and s is the y. Then, we have the points (0, 17400) and (6, 3000). The slope of these is 14400/-6 or -2400.
Now we just have the equation y = -2400x + b, and from the point (0, 17400) we can find that b is 17400. So, we have y = -2400x + 17400. Convert these back into t and s and you get your answer, s = -2400t + 17400.
