Answer:
-6
Step-by-step explanation:
Plug in (-1) for y: -3(-1) - 9
Simplify: Negative x Negative = Positive
-3(-1) = 3 so... 3-9
3 - 9 = -6
-3y - 9 is equivalent to -6
Vertical stretch occurs when a function value is multiplied by a number greater than 1.
For a function f(x), m*f(x) stretches f(x) in y direction if m is greater than 1.
From the given options we can see only A option lists such a case where an exponential function is being multiplied by a number greater than 1.
So, the answer to this question is A
Answer:
It's easy
Step-by-step explanation:
Use the order of operations in reverse to isolate the variable on one side of the equation. The order of operations is PEMDAS -- parentheses, exponents, multiplication, division, addition and subtraction. When solving for a variable, use the order in reverse -- SADMEP.
Perform the opposite operation to what is called for in the equation. If the equation requires you to multiply, you will divide. If the equation calls for subtraction, you will add.
Repeat the same operation on both sides of the equation. In the area of the triangle example, you arrived at the formula 100=1/2 (20h). You want to get the “h” by itself on one side of the equation. Multiply both sides of the equation by 2 to counteract the effect of the “1/2.” You then have 200=20h. Divide both sides of the equation by 20 to isolate the “h.” You find out that h=10.

150 times .1 is 15 so add 15 to 150 and get 165 then times that by .1 and get 16.5 add to 165 and get 181.5 times .1 and get 18.15 and add to 181.5 and get 199.65 as the answer.
Answer:
No solution
Step-by-step explanation:
6 + 2x = 2(x - 3)
6 + 2x = 2x-6
