If b>a, b-a=5 so b=5+a
ab=126, using b from above
a(5+a)=126
5a+a^2=126
a^2+5a-126=0
(a+14)(a-9)=0, since a<0 the numbers are
-14 and -9
Answer:
The answers in order are:
slope-intercept form
slope of a line
y-intercept
Step-by-step explanation:
These are the definitions of the terms.
y=mx+b is called slope-intercept form because it contains the slope (m) and y-intercept (b)
slope of a line is change in y over change in x (steepness) which is m
y-intercept is point line intercepts y-axis and is b
Answer:
25000(1-.14)^t
Step-by-step explanation:
it's just a simple decreasing equation it's your start number 1 minus your percentage because we're decreasing and to the power of t which equals time
Answer:
P(Both Green) = 22/145
Step-by-step explanation:
The probability of drawing green on the first drawn is P(First Green) = 12/30 = 2/5.
Having drawn green in the first drawn, the probability of drawning green in the second drawn is P(Second Green) = 11/29.
Then, the probability that both marbles are green is obtained by multiplying both probabilities as follows:
