Find x-intercept and y-intercept

x-intercept = 3 → (3, 0)

y-intercept = -6 → (0, -6)

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

Substitute:

m=\dfrac{-6-0}{0-3}=\dfrac{-6}{-3}=2

Answer: 2

Annie have 56 stamps that are 26 less than one half of my stamps how many stamps do i have?​
Ksivusya [100]

Answer:

<em>You have 164 stamps.</em>

Step-by-step explanation:

Let the no. of my stamps be 'x'

Half of x subtracted by 26 = 56

\frac{1}{2} x - 26 = 56

\frac{1}{2} x = 56 + 26 =  82

x = 82 x 2 =  164

Let's check

\frac{164}{2} - 26 = 56

\frac{164}{2} = 56 + 26

164     = 82 x 2

164 = 164!

The answer is correct.

What are the solutions of this quadratic equation?X2 - 10x= -34A.r=-8, -2B.r= 5 + 3iC.r=-5 + 3iD.r=-5 + 159
ololo11 [35]

The given equation is-

x^2-10x=-34

First, we move the independent term to the other side.

x^2-10x+34=0

Now, we have to use the quadratic equation to find the solutions.-

x_{1,2}=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}

Where, a = 1, b = -10, and c = 34.

Replacing these values in the formula, we have.

\begin{gathered} x_{1,2}=\frac{-(-10)\pm\sqrt[]{(-10)^2-4(1)(34)}}{2(1)} \\ x_{1,2}=\frac{10\pm\sqrt[]{100-136}}{2}=\frac{10\pm\sqrt[]{-36}}{2} \end{gathered}

But, there's no square root of -36 because it's a negative. To solve this issue, we use complex numbers that way, we would have solutions.

x_{1,2}=\frac{10\pm\sqrt[]{36}i}{2}=\frac{10\pm6i}{2}=5\pm3i<h2>Therefore, the solutions are</h2>\begin{gathered} x_1=5+3i \\ x_2=5-3i \end{gathered}The right answer is B.
