Answer:
y = x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 2) ← 2 points on the line
m = [tex]\frac{2-0}{0+2}[/tex] = [tex]\frac{2}{2}[/tex] = 1
The line crosses the y- axis at (0, 2) ⇒ c = 2
y = x + 2 ← equation of line

Write a quadratic equation whose factors are 4+3i and 4-3i.
Answers
Answer:
[tex]y=x^2-8x+25[/tex]
Step-by-step explanation:
To answer this question, we will work backwards.
We know that a factor is 4+3i. This means that:
[tex](x-(4+3i))=0[/tex]
Hence, we will eliminate the imaginary and convert this into standard form.
First, distribute the negative:
[tex]x-4-3i=0[/tex]
Add 3i to both sides:
[tex]x-4=3i[/tex]
Square both sides:
[tex](x-4)^2=(3i)^2[/tex]
Expand:
[tex]x^2-8x+16=9(-1)=-9[/tex]
Add 9 to both sides:
[tex]x^2-8x+25=0[/tex]
Hence, our quadratic equation is:
[tex]y=x^2-8x+25[/tex]
Notes:
We will get the same equation if we use (4-3i). This is because we square the (3i) regardless of its sign, making it positive.

What is the image of (2,3)(2,3) after a reflection over the line y=-xy=−x?
Answers
Answer:
After the reflection over the line y = -x, the image of the point is: (-3,-2)
Step-by-step explanation:
When a given point is reflected over a line the point only changes place but the distance between the point and the line remains same.
Let (x,y) be a point on the plane
and
y = -x be a line on the plane
When a point is reflected over a line y = -x , the coordinates of the point are exchanged which means x becomes y and y becomes x and both are negated
So (x,y) will become (-y,-x)
Given point is:
(2,3)
After the reflection over the line y = -x, the image of the point is: (-3,-2)

If e^xy-y^2=e-4,
then at x=1/2 and y=2,
dy/dx=?
Answers
Answer:
If [tex]e^{x\cdot y}-y^{2} = e-4[/tex], then at [tex]x = \frac{1}{2}[/tex] and [tex]y = 2[/tex], [tex]\frac{dy}{dx} \approx 2.059[/tex].
Step-by-step explanation:
Let [tex]e^{x\cdot y}-y^{2} = e-4[/tex]. At first we determine the first derivative of the function by implicit differentiation:
[tex]e^{x\cdot y}\cdot \left(y+x\cdot \frac{dy}{dx} \right)-2\cdot y \cdot \frac{dy}{dx} = 0[/tex]
[tex]y\cdot e^{x\cdot y}+x\cdot e^{x\cdot y}\cdot \frac{dy}{dx} -2\cdot y\cdot \frac{dy}{dx} = 0[/tex]
[tex]y\cdot e^{x\cdot y}= (2\cdot y -x\cdot e^{x\cdot y})\cdot \frac{dy}{dx}[/tex]
[tex]\frac{dy}{dx} = \frac{y\cdot e^{x\cdot y}}{2\cdot y - x\cdot e^{x\cdot y}}[/tex]
If we know that [tex]x = \frac{1}{2}[/tex] and [tex]y = 2[/tex], then the computed value of the function is:
[tex]\frac{dy}{dx} = \frac{(2)\cdot e^{\left(\frac{1}{2} \right)\cdot (2)}}{2\cdot (2)-\left(\frac{1}{2} \right)\cdot e^{\left(\frac{1}{2} \right)\cdot (2)}}[/tex]
[tex]\frac{dy}{dx} \approx 2.059[/tex]
If [tex]e^{x\cdot y}-y^{2} = e-4[/tex], then at [tex]x = \frac{1}{2}[/tex] and [tex]y = 2[/tex], [tex]\frac{dy}{dx} \approx 2.059[/tex].

A single die is rolled twice. Find the probability of rolling an
Odd number the first time and a number greater than 4 the second time.
Answers
Answer: 1/6
Step-by-step explanation:
A die has 6 numbers which are 1, 2, 3, 4, 5 and 6.
Odd numbers in a die = 1, 3 and 6
Numbers greater than 4 = 5 and 6
Probability of rolling an odd number = 3/6 = 1/2
Probability of rolling a number greater than 4 = 2/6 = 1/3
We then multiply both values gotten. This will be:
= 1/2 × 1/3
= 1/6
Therefore, the probability of rolling an odd number the first time and a number greater than 4 the second time is 1/6.
The probability of rolling an odd number the first time and a number greater than 4 the second time is 1/6
The sample space of a single die is
[tex]\mathbf{S = \{1,2,3,4,5,6\}}[/tex]
So, the total sample is 6
The odd numbers are
[tex]\mathbf{Odd = \{1,3,5\}}[/tex] --- 3 odd numbers.
So, the probability of selecting an odd number is:
[tex]\mathbf{P(Odd) = \frac 36}[/tex]
Simplify
[tex]\mathbf{P(Odd) = \frac 12}[/tex]
The numbers greater than 4 are
[tex]\mathbf{Greater = \{5,6\}}[/tex] --- 2 numbers greater than 4.
So, the probability of selecting a number greater than 4 is:
[tex]\mathbf{P(Greater) = \frac 26}[/tex]
Simplify
[tex]\mathbf{P(Greater) = \frac 13}[/tex]
The probability of rolling an odd number the first time and a number greater than 4 the second time is calculated as follows:
[tex]\mathbf{P = P(Odd) \times P(Greater)}[/tex]
So, we have:
[tex]\mathbf{P = \frac 12 \times \frac 13}[/tex]
[tex]\mathbf{P = \frac 16}[/tex]
Hence, the probability is 1/6
