The associative property of addition is pretty much just any numbers in place of these: a + (b + c) = (a + b) + c. Therefore, your answer would be d) (6 + 1) + 9 = 6 + (1 + 9)
A) Slope = 5, for the y intercept plug 0 into x, so y=5(0)+10 =10. So the y-intercept is (0,10)
c) I added the graph below. First you plot the y intercept, (0,10). Then count 5 up and 1 right and plot a point because the slope is (5/1) "slope is easy and fun, rise over run." You can go the opposite way too, 5 down and 1 left and then plot a point. Plot 5-7 points. The x-axis is time, because that is the independent variable and the y-axis is baskets of berries because that is the dependent variable.
Answer:
A) y = x^2 -1
B) -y = 2x^2 +1 We multiply B) by -1
B) y = -2x^2 -1
We can then say x^2 -1 = -2x^2 -1
3 x^2 = 0
x = 0
************* Double-Check: ******************
Equation A) y = -1 and
Equation B) y = -1
Step-by-step explanation:
The answer is 266 but estimated is 260
