Answer:
(a + b -c) x (x +y )
Step-by-step explanation:
Firstly, factor out x from the expression
Then, factor out the y from the expression
Answer:
3.50 x+18.00 ≤ 40.00
Step-by-step explanation:
She pays 18 dollars each moth, therefore that quantity won't change, so you will have to add. Each movie that she watches is an additional 3.50, then we have 3.50 x, x being the quantity of movies that she watches. She can only afford up to 40 dollars, then everything that she spends has to be less or equal to 40.
Answer:
-18
Step-by-step explanation:
Multiply the numbers
3*6
-7 + 9 - 18 - (5 + 9) ÷ 7
Add the numbers
5+9
-7 + 9 - 18 - 14 ÷ 7
Divide the numbers
14÷ 7
-7 + 9 - 18 - 2
Calculate the sum or difference
-18
Answer = -18
Answer:
5
Step-by-step explanation:
Replace 20 instead of m
20/4=5
Answer:
(- 1, 2)
Step-by-step explanation:
Given a quadratic in standard form y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
= - 
f(x) = x² + 2x + 3 ← is in standard form
with a = 1 and b = 2, hence
= - 
= - 1
Substitute x = - 1 into f(x) for corresponding value of y
f(- 1) = (- 1)² + 2(- 1) + 3 = 1 - 2 + 3 = 2
vertex = (- 1, 2 )
