Answer:

B (0,2)

Step-by-step explanation:

y-intercept means where the line crosses the y-axis. The y-axis is the vertical line. Coordinate points are recorded as (x,y). The y-intercept is (0,2). Aka, when x = 0, y = 2.

Suppose you toss a coin 100 times and get 60 heads and 40 tails. Based on these results what is the probability that the next fl

Nata [24]

The probability is 1/2. Even if you flip heads 100 times in a row, you still have a 50/50 chance of flipping heads or tails. The probability does not change no matter how many times you flip a certain side.

Suppose x is a real number and epsilon > 0. Prove that (x - epsilon, x epsilon) is a neighborhood of each of its members; in

kaheart [24]

Answer:

See proof below

Step-by-step explanation:

We will use properties of inequalities during the proof.

Let $y\in (x-\epsilon,x+\epsilon)$ . then we have that $x-\epsilon$ . Hence, it makes sense to define the positive number delta as $\delta=\min\{x+\epsilon-y,y-(x-\epsilon)\}$ (the inequality guarantees that these numbers are positive).

Intuitively, delta is the shortest distance from y to the endpoints of the interval. Now, we claim that $(y-\delta,y+\delta)\subseteq (x-\epsilon,x+\epsilon)$ , and if we prove this, we are done. To prove it, let $z\in (y-\delta,y+\delta)$ , then $y-\delta$ . First, $\delta \leq y-(x-\epsilon)$ then $-\delta \geq -y+x-\epsilon$ hence $z>y-\delta \geq x-\epsilon$

On the other hand, $\delta \leq x+\epsilon-y$ then $z$ hence $z$ . Combining the inequalities, we have that $x-\epsilon$ , therefore $(y-\delta,y+\delta)\subseteq (x-\epsilon,x+\epsilon)$ as required.

Find the approximate solution of this system of equations. y=x^2+5x+3 y=square root2x+5

Anni [7]

We have that
y=x²<span>+5x+3
y=</span>√(<span>2x+5)

using a graph tool
see the attached figure

the solution is
x=-0.175
y=2.156

therefore

the answer is the option
