Answer:
perimeter of the rectangle =24 cm
sum of all side is perimeter.
length = 8 breadth =4 ( half of other side)
Area of the rectangle = l × b
= 8 × 4
= 32 cm

Answer:
r(t) = 15t+500
Step-by-step explanation:
Since the amount of money (r) is a function of the time (t) we will make it the y-value. t is how much time and he gets $15 a minute so we multiply t by 15. 500 is how much he gets paid for doing it. If he showed up and just left, he would still get 500.
Answer:
Step-by-step explanation:
Point B is 6 units below and 4 units to the right of A, so the slope is ...
slope = (change in y)/(change in x) = -6/4 = -3/2
Point R corresponds to point B, so will be 6 units below and 4 units to the right of point Q.
R = Q + (4, -6) = (2, -4) + (4, -6) = (2+4, -4-6)
R = (6, -10)

E hope this helps but hi my name is hailey
Explanation: Here we have function f(x) = 2x - 5
and we're asked to find f(x - 1).
Don't be thrown off if you're asked to plus a variable into a function.
If f(x) = 2x - 5, then f(x - 1) = 2(x - 1) - 5.
<em>Remember to use parenthses when substituting into a function.</em>
So simplifying on the right side, we would distribute the 2
through the parenthses and we have 2x -2 - 5.
Now combining like terms, we have 2x - 7
