Answer:
(5, 4)
Step-by-step explanation:
The x goes from negative to positive, but the y stays the same.
Answer:
7/20.
Step-by-step explanation:
Simply convert 35% to a fraction. You get 35/100. Then, you are expected to leave your fraction in its simplest form. Do the simplification, and you will derive <u>7/20</u>.
Answer:
b = 77.4 ⇒ answer (b)
Step-by-step explanation:
∵ m∠A = 44° , m∠B = 45° , BC = 76
By using sin Rule:
∵ AC/sinB = BC/sinA
∴ AC/sin45 = 76/sin44
∴ AC = (76 × sin45) ÷ sin44 = 77.4
∵ AC = b
∴ b = 77.4 answer (b)
Answer: There are no real solutions.
Step-by-step explanation:
We have the equation:
x = y^2
y = x + 3/2
To solve this, we can start by noticing that x is already isolated in the first equation, then we can replace it in the second equation to get:
y = y^2 + 3/2
And now we can rewrite this as:
y^2 - y + 3/2 = 0
This is a quadratic equation, and the solutions can be calculated with Bhaskara's equation, the solutions are:
We have a negative number inside the square root, this means that the solutions are complex numbers.
Then we can conclude that the system of equations has no real solutions.
