1) When graphing a line from an equation, the first point to plot is the ​
Dafna1 [17]

Answer:

y-intercept (b)

Step-by-step explanation:

If you are working with a slope-intercept equation, that is

y = mx + b

Then you want to put the y-intercept on the graph first. It is the b in the equation it is often at the end of the equation. It is the number that is NOT right next to the x.

Then use the slope (the m, that IS right next to the x) to find the next point. Slope is like directions from one point to another.

Then you can draw the line.

Answer: Option A

x=\frac{3+i}{2} or x=\frac{3-i}{2}

Step-by-step explanation:

Use the quadratic formula to find the zeros of the function.

For a function of the form

ax ^ 2 + bx + c = 0

The quadratic formula is:

x=\frac{-b\±\sqrt{b^2-4ac}}{2a}

In this case the function is:

2x^2-6x+5=0

So

a=2\\b=-6\\c=5

Then using the quadratic formula we have that:

x=\frac{-(-6)\±\sqrt{(-6)^2-4(2)(5)}}{2(2)}

x=\frac{6\±\sqrt{36-40}}{4}

x=\frac{6\±\sqrt{-4}}{4}

Remember that \sqrt{-1}=i

x=\frac{6\±\sqrt{4}*\sqrt{-1}}{4}

x=\frac{6\±\sqrt{4}i}{4}

x=\frac{6\±2i}{4}

x=\frac{3\±i}{2}

x=\frac{3+i}{2} or x=\frac{3-i}{2}

How do I solve this .... question in the image. <br><br>thank you​
dezoksy [38]

Answer:

Below

Step-by-step explanation:

● x-20 = y+20 (1)

● 2(y-22) = x+22 (2)

This is a system of simulataneous equations

Let's simplify the expressions first

● x -20 = y + 20 (1)

Add 20 to both sides

● x -20 + 20 = y+20 +20

● x = y + 40 (1)

● 2(y-22) = x+22 (2)

● 2y - 44 = x +22

Substrat 22 from both sides

● 2y-44-22 = x+22-22

● 2y -66 = x (2)

This is the new system:

● x = y+40 (1)

● x = 2y-66 (2)

Substract (2) from (1)

● x-x = y+40-(2y-66)

● y+40-2y+66 = 0

● -y +106 = 0

● y = 106

Replace y with 106 in (1)

● x = y +40

● x = 106+40

● x = 146

So the solutions are (146,106)
