1. Equation: 4x + 6y = 40
Answer:!4x + 6y - 40 = 0
2x + 3y - 20 = 0
2. Equation: 2x + 6y = 26
Answer: 2x + 6y - 26 = 0
x + 3 y - 13 = 0
Answer: We will see in the next example how using the Quadratic Formula to solve an equation with a perfect square also gives just one solution. Solve 4{x}^{2}-20x=-25
Step-by-step explanation:
Answer: The first and last options are correct.
f(x) = pi/4 cos (pix/5 - pi/2)
f(x) = pi/4 sin (pix/5)
Step-by-step explanation
The graph shows that A = pi/4.
B = 10, so the period = 2pi/10 = pi/5.
sin and cos are cofunctions, so a phase shift of -pi/2 makes the two functions equal to each other.
Hope this helps :)
Answer:
b = 1/4m
Step-by-step explanation:
A baker uses 4 berries for every muffin which equation can be used to find the number of berries b needed to make m muffins
Given :
Berries = b
Muffins = m
4 berries for every muffin
4b = m - - - (1)
Th number of berries to make m muffins:
Make b the subject :
Divide both sides by 4
b = m/4
