Answer:
When added together, the sum of the given functions have a value of -6.
Step-by-step explanation:
When we see f(-2), it means that our value of x for the f(x) function is -2. When we see g(5), it means that our value of x for the g(x) function is 5. So, let's use this information and plug it into our equation.
f(-2) + f(5) = (3(-2) - 1) + (-(5) + 6)
Multiply 3 by -2 and distribute the negative to 5.
f(-2) + f(5) = (-6 - 1) + (-5 + 6)
Subtract 1 from -6 and add 6 to -5.
f(-2) + f(5) = (-7) + (1)
Add 1 to -7.
f(-2) + f(5) = -6
So, when added, the sum of the functions is -6.
A.
Multiply the number of days, x by 50 per day to get 50x.
Next multiply the number of miles driven to the amount she gets per mile: 0.60 x 200 = $120
Now add both together to equal the total of 1620.
The equation becomes: 50x +120 = 1620
B.
50x +120 = 1620
Step 1: subtract 120 from both sides ( subtraction property of equality):
50x = 1500
Step 2: Divide both sides by 50 ( division property of equality):
x = 1500 / 50
x = 30

Answer:
Step-by-step explanation:
radius of semicircle =4.7/2 m
area of semicircle=1/2 πr²
=1/2 ×π×(4.7)²
≈8.67 m²
fertiliser=8.67×20
=173.4
≈173 gm
