The correct answer will be b, because x is always to the left or right. If it is negative you going to the left and if it is positive your going to the right. With y it's always up or down so if it's positive your going up and if it's negative you going down.

Find all complex solutions of 5x^2-6x+2=0.
gregori [183]
We use quadratic formula for that one
remember that √-1=i

so

for
ax^2+bx+c=0
x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}
so
given
5x^2-6x+2=0
a=5
b=-6
c=2

x=\frac{-(-6)+/-\sqrt{(-6)^2-4(5)(2)}}{2(5)}
x=\frac{6+/-\sqrt{36-40}}{10}
x=\frac{6+/-\sqrt{-4}}{10}
x=\frac{6+/-2i}{10}

x=\frac{3}{5}+\frac{i}{5}, \frac{3}{5}-\frac{i}{5}

What is the value of the expression below when x=3<br> 10x²- 7x + 10
Andreas93 [3]

Answer: 79

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

<u>Given information</u>

10x² - 7x + 10

x = 3

<u>Substitute the value into the expression</u>

= 10 (3)² - 7 (3) + 10

<u>Simplify by multiplication</u>

= 10 (9) - 21 + 10

= 90 - 21 + 10

<u>Simplify by subtraction</u>

= 69 + 10

<u>Simplify by addition</u>

= 79

Hope this helps!! :)

Help ,with number 9, please
sleet_krkn [62]
9 is linear. Rearrange to get into standard line format

2x + 3y = 5
3y = -2x + 5
y = -2/3x + 5/3

Now, plot a point at 5/3 on the y axis. Go down 2 and right 3 and put another point
Then draw a line running through both points.
