The slope of a line between 2 points is given by the formula
m = y2 - y1/x2 - x1
m= 22-6/20-12
m= 16/8= 2
slope is 2
Answer:
train a weighs 177 and train b weighs 90
Step-by-step explanation:
train a weighs 87 more tons than train b but both combined is 267.
a + b = 267
267 - 87 = 180
divide by two to get the weight of train b
180/2 = 90
add the 87 to find the weight of train a
90 + 87 = 177
check
90 + 90 + 87 = 267
this is my first time answering a question, hope this helped :)
The problem says that 10x^2 = 80x. Since x is guaranteed not to equal zero, divide both sides by x; 10x=80. Divide both sides by 10 and x=8
It would be {x,y} = {7,-5}
Answer:$114.47
