Answer: Commutative Property of Addition
This property says that A+B = B+A. The order of addition doesn't matter.
As an example, 2+3 = 3+2 since both sides evaluate to 5.

Two trucks leave a warehouse at the same time, traveling in opposite directions. The rate of the faster truck exceeds that of the slower truck by miles per hour. After hours, they are miles apart. What are the rates of the trucks? Use the table below to organize your work
Answer:
Speed of the slower truck = 57.5 miles/hour
Speed of the faster truck = 62.5 miles/hour
Step-by-step explanation:
Using missing information;
Assume;
Speed of the slower truck = a
Speed of the faster truck = a + 5
Distance traveled by the slower truck = d
Distance traveled by the faster truck = 600 - d
So,
a(5) = d ........ Eq1
(a+5)(5) = 600 - d
5a + 25 = 600 - d
So,
5a + 25 = 600 - 5a
10a = 575
a = 57.5
Speed of the slower truck = 57.5 miles/hour
Speed of the faster truck = a + 5
Speed of the faster truck = 57.5 + 5
Speed of the faster truck = 62.5 miles/hour

Three rays have a common vertex on a line. Write and solve equations to find the measures of m and n
Answer:
n = 90 - 62
n = 28º
m = 180 - (62 + n + 27)
m = 180 - (62 + 28 + 27)
m = 180 - 117
m = 63º
in the function f(x) = (x+2)2 -3 the minimum value occurs when x is
Answer:
x=2
Step-by-step explanation:
the minimum value of y is when x = 2.
Answer:
The minimum is at x = -2
Step-by-step explanation:
f(x) = (x+2)^2 -3
This is in vertex form
f(x) = ( x-h)^2 +k where (h,k) is the vertex
Since this is an upwards opening parabola the vertex is the minimum
f(x) = (x- -2)^2 -3
The vertex is (-2,-3)
The minimum is at x = -2
Which is the best explanation for why − √ 10 is irrational?
Step-by-step explanation:
- square root of 10 is irrational because it is less than zero. - square root of 10 is irrational because it is not a whole number.
Upon prime factorizing 10 i.e. 21 × 51, 2 is in odd power. Therefore, the square root of 10 is irrational.

At Walmart, a $525 bicycle is marked, "Get a 30% discount." What is the sale
price of the bicycle?
Answer:
367.50
Step-by-step explanation:
First find the discount
525 * 30%
525 * .30
157.50
Subtract this from the price
525-175.50
367.50
This is the new price
Answer:
367.5
Step-by-step explanation:
30% means 0.30
1 - 0.30 = 0.70
525 x 0.70 = 367.5

At the moment a certain medicine is injected, its concentration in the bloodstream is 120 milligrams per liter. From that moment forward, the medicine's concentration drops by 30% percent each hour. Write a function that gives the medicine's concentration in milligrams per liter, C(t), t hours after the medicine was injected. If anyone responds, thank you <3
Answer: [tex]C(t) = 120(1-0.30)^t[/tex]
Step-by-step explanation:
Exponential equation for decay:[tex]y= A(1-r)^t[/tex], where A = initial value, r= decay rate , t= time.
As per given, A = 120ml , r= 0.30
[tex]C(t) = 120(1-0.30)^t[/tex]
Hence, the required function that gives the medicine's concentration in milligrams per liter, C(t), t hours after the medicine was injected.
[tex]C(t) = 120(1-0.30)^t[/tex]
