Answer:

A) is correct

Step-by-step explanation:

(-3)**2 = 9,  not equal -9

The issue is negative numbers can only be imaginary numbers. The sq root of -9 would be 3i, where i is defined as the sq root of -1.

What is the equation of the graphed line written in
Andrew [12]

<u>Given</u>:

Given that the graph of the linear equation.

We need to determine the equation of the graph.

<u>Slope</u>:

The slope of the equation can be determined using the formula,

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

Let us substitute the coordinates (2,0) and (0,-4) in the above formula, we get;

m=\frac{-4-0}{0-2}

m=\frac{-4}{-2}

m=2

Thus, the slope of the equation is 2.

<u>y - intercept:</u>

The y - intercept of the equation is the value of y when x = 0.

Hence, from the graph, it is obvious that when x = 0, the value of y is -4.

Therefore, the value of the y - intercept is b = -4.

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

y=mx+b

Substituting the values, we have;

y=2x-4

Subtracting both sides by 2x, we have;

-2x+y=-4

Dividing both sides by -1, we get;

2x-y=4

Thus, the equation of the line is 2x-y=4

Hence, Option B is the correct answer.

-10(1 - 9x) + 6(x - 10) <br> Pics pls
Galina-37 [17]

Answer:

  • \boxed{\sf{96x-70}}}

Step-by-step explanation:

Use the distributive property.

<h3>What is a distributive property?</h3>

Distributive property is a serving to distribute or allot or disperse.

<u>Distributive property:</u>

A(B+C)=AB+AC

A(B-C)=AB-AC

-10(1-9x)+6(x-10)

<u>Expand.</u>

-10(1-9x)

-10*1=-10

-10*9x=90x

\longrightarrow \sf{=-10+90x+6\left(x-10\right)}}

6(x-10)

6*x=6x

6*10=60

6x-60

<u>Rewrite the problem down.</u>

= -10+90x+6x-60

<u>Combine like terms.</u>

90x+6x-10-60

<u>Add the numbers from left to right.</u>

90x+6x=96x

96x-10-60

<u>Finally, subtract the numbers from left to right.</u>

-10-60=-70

\Longrightarrow \boxed{\sf{96x-70}}

Therefore, the final answer is<u> 96x-70.</u>

I hope this helps, let me know if you have any questions.
