Answer:
the answer is B because it has only one unknown and also it is a linear equation so it will have only one answer which is (2 )
Answer:
(x, y) = (-1.4, 1.6)
Step-by-step explanation:
The graph shows the solution pretty clearly. It seems no estimation is required.
Answer:
60 m^2
Step-by-step explanation:
To solve the area, solve the triangle and rectangle separately.
Solve the rectangle:
Multiply 10 and 4 to get the area of 40 m^2.
Solve the triangle:
Multiply 10 and 4, then divide by 2. The formula for a triangle's area is base*height/2. The area is 20.
Add together:
40+20 = 60 m^2
Answer:x= 9
Step-by-step explanation:
-4(x+5) = 16
-4*x= -4x -4*5= -20
16 - -20= 36
-4x/-4= x 36/-4=9
Answer:
f(2) = -6

Order of Operations: BPEMDAS
Substitution and Evaluation
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -2x² + 4x - 6
f(2) is x = 2
<u>Step 2: Solve</u>
- Substitute: f(2) = -2(2)² + 4(2) - 6
- Exponents: f(2) = -2(4) + 4(2) - 6
- Multiply: f(2) = -8 + 8 - 6
- Add: f(2) = -6
