Answer:
Step-by-step explanation:
Using elimination means you either add the two equations together or subtract them. You can first multiply the second equation by 2, so you get 4x - 6y = 24. Then you add the two equations together to get 9x = 42. Then you solve for x and then you can solve for y.
Answer:
Linear Function
Step-by-step explanation:
Given
The table showing values of x and y
Required
Determine the type of function
To determine the type of function, the table represents;
One will need to determine the table equation.
Start by solving for the slope;
When x - 0; y = 0 and When x = 80; y = 60.
This gives
The formula is determine as follows;
When x - 0; y = 0; m = 3/4; This gives
Open Bracket
The above is an example of a linear equation.
<em>Hence; option B answers the question</em>
Answer: D
Step-by-step explanation:
As you can see it is switch from -3 to 3.
Why?
Because each time it is being multiplied by -1 so it switches from negative to positive and geometric sequences involve multiplication (and division so technically it could be dividing by -1).
Answer:
2: The perimeter of the base is 37 units.
Step-by-step explanation:
1. A = LW = 21 * 16 = 336 units^2 True
2. P = 2(L + W) = 2(21 + 16) = 2(37) = 74 units False
3. H = 21 units True
4. SA = 2LW + 2H(L + W) = 2(21)(16) + 2(21)(21 + 16) = 2226 units^2 True
the lateral surface area of the figure is 660 sq ft
(but the answer is not matching with the options)
Step-by-step explanation: this figure is called cylinder. the lateral surface area means the area of curved surface.
here the diameter is 10 ft
so radius = diameter/2 = 10/2 ft = 5ft
again, height = 21ft
now the lateral surface area = perimeter of the circular surface X height
= 2X pie X r X h ( here r is the radius and h is height and we will take pie as 22/7)
= 2 X (22/7) X 10 X 21 sq ft
= 2 X 22 X 5 X 3 sq ft
=660 sq ft
( suggest you to recheck the options)
