Since AD and CD are equivalent to each other, put them together in a equation where they equal each other.
AD=CD
3x+4=x+6
Subtract x from both sides
2x+4=6
Subtract 4 from both sides
2x=2
Divide 2 on both sides
Final Answer: x= 1
X = -3 it's practically the y intercept in which x is equals 0
Answer:
1/2 make a sketch of the corresponding triangle
Step-by-step explanation:
Yes, 3/2 = 1.5 $ per bagel
4/6 also is 1.5
18/ 12 = 1.5
Which makes it a a proportional relationship of 1 bagel for 1.50.
Berries are also proportional. 9/3 =3
15/5 = 3
And same for 30/ 10
Therefore it costs $3 per pound of berries
Answer:
The regression line is not a good model because there is a pattern in the residual plot.
Step-by-step explanation:
Given is a residual plot for a data set
The residual plot shows scatter plot of x and y
The plotting of points show that there is not likely to be a linear trend of relation between the two variables. It is more likely to be parabolic or exponential.
Hence the regression line cannot be a good model as they do not approach 0.
Also there is not a pattern of linear trend.
D) The regression line is not a good model because there is a pattern in the residual plot.
