Answer:
Option A, -4
Step-by-step explanation:
<u>Step 1: Make an equation to represent the problem</u>
(-9)(x) = 36
<u>Step 2: Solve for x by dividing both sides by -9</u>
-9x / -9 = 36 / -9
x = -4
Answer: Option A, -4
You just substitute the value of x in the given equation:
f(x) = 2x^2 - 5
f(-4) = 2 (-4)^2 -5 = 27
f(x) : a name given to the equation
f(-4): refer to the equation when the value of the independent variable x has the value between the brackets.
Number of plants = 5
Amount of soil present for 5 plants = 3/4 gallons
Now here we have to find how much soil will each plant get.
So we have to apply unitary method here to find how much would each plant get the share of soil.
Soil required by 5 plants = 3/4 gallons
Soil required by 1 plant = 3/4 divided by 5 = 3/20 gallons
Answer: Each plant will get 3/20 gallons of soil.
Answer:
13750
Step-by-step explanation:
Let 'x' be the number of bulbs produced in second shift
Number of bulbs produced in 1st shift= 5.5x
Total number of bulbs= 5.5x+x
16250=5.5x+x
x=2500
Number of bulbs produced in shift 1= 5.5×2500
= 13750
