Answer: Add the number previously added multiplied by 3;
+3x, where x is the number that was added previously
Step-by-step explanation:
3+5=8. That's the first equation, where 5 is x. Then the next equation, 8+3x=23. 8+15=23. It works for all of the equations, so that's the pattern.
Answer: 42
Step-by-step explanation: you would do 63 divided by 3 then you would get 21 and do 21×2 and get 42
The scatterplot shown includes the (blue) least-squares regression line, whose equation is y = .975 + .005x, where y is calories (in thousands) and x is years after 1960. Choose the correct statement.
Answer: In the given regression equation, the calories are in thousands. Therefore, the slope 0.005 (0.005 x 1000 =5 calories) means the consumption is increasing at a rate of 5 calories per year.
Hence the option a. Consumption is increasing at a rate of 5 calories per year. is correct
Answer:
x=8,y=-1
Step-by-step explanation:
x-2y=10
x=10+2y
10+2y+3y=5
5y=-5
y=-1
x-2(-1)=10
x=8
Answer:c
Step-by-step explanation:
Because the x’s repeat
