10 is the bace of 10 because when its in exponets its 6 so 10 powerd by 6
The answer to number 2 is 46 because
Answer:
Inside the jar there's 16 nickels and 35 quarters.
Step-by-step explanation:
Since there are only nickels and quarters in the jar, the sum of the number of nickels and the number of quarters inside it must be equal to the total number of coins in the jar. So
nickels + quarters = 51
We know the total value inside the jar, to obtain this value we must multiply the amount of each kind of coin by it's value and sum it. So we have:
0.05*nickels + 0.25*quarters = 9.55
We now have two equations and two variables, so we can solve them as follows:
nickels + quarters = 51
0.05*nickels + 0.25*quarters = 9.55
From the first equation:
nickels = 51 - quarters
0.05*(51 - quarters) + 0.25*quarters = 9.55
2.55 - 0.05*quarters + 0.25*quarters = 9.55
0.2*quarters = 9.55 - 2.55
quarters = 7/0.2 = 35
nickels = 51 - 35 = 16
Inside the jar there's 16 nickels and 35 quarters.
Answer:
The bottom right graph is correct, with the y-intercept at -3 and the graph shaded to the right.
Step-by-step explanation:
The inequality of y < 4x - 3 is written in slope-intercept form (y = mx + b), where m = slope and b = y-intercept. The difference between a linear equation and linear inequality is that an equation only produces one answer while an inequality and can have several answers. Because the y-intercept = -3, the graph should cross the y-axis at -3, which it does for all the given graphs. However, the slope is 4, which means that the change in 'y' over the change in 'x' is 4/1 - up four units and to the right one unit. This would give us the choice of the bottom to graphs.
Since the inequality is y < 4x - 3, then all answers must be less than the total value of the expression, which means we shade to the right of the line.
