Answer:
f(1) = - 1
f(-1) = - 2
Step-by-step explanation:
f(1) will lie in the function f(x) = - 2x + 1
Therefore,
f(x) = - 2x + 1
Plug x = 1
f(1) = - 2*1 + 1 = - 2 + 1 = - 1
f(-1) will lie in the function f(x) = - x - 1
Therefore,
f(x) = - x - 1
Plug x = - 1
f(-1) = - 1 - 1 = - 2
Answer:
-1, 0, 1, 11, 3Step-by-step explanation:
Function 1
f(x) = -2x + 1f(1) = -2(1) + 1 = -2 + 1 = -1Function 2
f(x) = -x - 1f(-1) = -(-1) - 1 = 1 - 1 = 0Function 3
f(x) = x + 3f(-2) = -2 + 3 = 1Function 4
f(x) = 2x + 1f(5) = 2(5) + 1 = 11Function 5
f(x) = 3f(6) = 312.

Mr. White is renting a small truck for one week and a few additional days d. He does not have to pay a per mile fee. Evaluate the expression 280+80d to find how much he will pay for a 9-day rental.
Answers
The amount of money paid for the 9-day rental will be $1000.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Mr White is renting a small truck for one week and a few additional days d. He does not have to pay a per-mile fee. The expression is 280+80d.
The amount of money for a 9-day rental will be calculated as,
A = 280+80d
A = 280+(80 x 9)
A = $1000
Therefore, the amount of money paid for the 9-day rental will be $1000.

Answers
Hey in this type of questions there's no formula, you need to use your logic.
#Note that the full degree or a triangle is 180°
#The L in triangle is 90°
I see that you want to try to do it by yourself, i will give you the tips. to get the <BAD
#since <DAC is 90°, The ADB is 90° (180°-90°)
<BAD = 180° - 90° - 25° = 65°
Now, try to find <BCA yourself.
Tell me if you give up, i will tell you lol.
The angles of a triangle add up to 180 degrees.
The second angle is 20 degrees larger than the smallest angle.
The third angle is 3 times as big as the smallest angle.
Find the measure of the smallest angle (in degrees)
Answers
Answer: 32 degrees
Step-by-step explanation:
small angle : x
middle angle: x + 20
large angle: 3x
Form an equation: 5x + 20 = 180
5x = 180 - 20
5x = 160
x = 160/5
x = 32

Answers
Answer:
8t + u - 7 or -7 + u + 8t ( to match the multiple choice answers)
Step-by-step explanation:
the perimeter is the distance around an object, therefore we need to add up all three sides of the triangle to get the perimeter
2t + 2 + 6t - 7 + u - 2 = perimeter
combine like terms to simplify
2t + 6t + u + 2 - 2 - 7
