Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. So the y-intercept of y = 3x + 2 is 2
Answer:
+8x+15
Step-by-step explanation:
we apply the distributive property
so we have
(x+3)*(x+5)
x*x+5*x+3*x+3*5
finally
we have
+8x+15
Hello!
The mean is the average. The median is the middle number of the data set, in terms of quantity. The mode is the number that appears the most. The range is the difference between the largest and smallest numbers in the set.
Therefore, our answers are below.
Range: Difference between largest and smallest data piece.
Median: Middle value of a set of data
Mode: most commonly occurring number(s)
Mean: the sum of the data divided by the quantity of the data items.
I hope this helps!

Please see attached picture for full solution.
(From the 4th to 5th line, I multiplied both sides by 8)
Answer:
N=250
Step-by-step explanation:
"twice as many nickels as dimes" means N =2D [eq1]
"collection of nickels and dimes is worth $25" means
5N + 10D = 2500 [eq2]
(To avoid using decimal points, PLZ express everything in cents.)
Substitution (substitute N from eq1 into eq2]:
5(2D) + 10D = 2500
10D + 10D = 2500
20D = 2500
D = 125
N=2D [eq1 again]
N=2(125)
N=250
Check:
Is 5(250) + 10(125) = 2500 ?
1250 + 1250 = 2500 ?
2500 = 2500 ?yes
