Answer:
3b + 16
Each book costs 3 dollars and b is the number of books borrowed that one month. In that month, she also needs to pay 16 dollars for her membership so if you put all of it together, you get 3b + 16.
42 to ^5 is standard form
To find the angle use arc tan (-5/-7) which simplifies tips arctan(5/7). arc tan is tan to the power -1, which is also called inverse tan. The heading of the angle, if you drew this out on a graph your angle would be in the third quadrant and therefore the heading is south of west.
Answer:
slope= -¾
Step-by-step explanation:
3x +4y= 9
Let's rewrite the equation into the form of y= mx +b (known as slope-intercept form), where m is the slope and b is the y-intercept.
Keep the y term on the left-hand side of the equation and move all the other terms to the right-hand side.
4y= -3x +9
For the coefficient of y to be 1, divide both sides of the equation by 4.
the value of x is 120 ....
