(2-x)²=36
Answers
Answer:
Step-by-step explanation:
You have to factor but we start by simplifying both sides which will be x^2-4x+4=36. Then you subtract 36 from both sides
x^2-4x+4-36=36-36
x2-4x-32
Now that the equation is set up, you can factor
(x+4)(x-8)Set the factors equal to 0
x=-4 or
x=8

What is the answer to 8x + 4( 4x - 3) = 4( 6x + 4) - 4
Answers
Answer:
x=24
Step-by-step explanation:
8x + 4(4x - 3) = 4(6x + 4) - 4
8x + 16x - 12 = 24x + 16 - 4
24x - 12 = 24x + 12
24x = 24x + 12 + 12
24x = 24x + 24
24x/24x = 24
x = 24
Answer:
0
Step-by-step explanation:
8x + 4(4x - 3) = 4(6x + 4) - 4
8x + 16x - 12 = 24x + 16 - 4
24x - 12 = 24x + 12
-24x -24x
-12 = 12

The equation of line will be;
⇒ y = - 3/5x + 3
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
James draws a line that has an x-intercept of "-5" and y-intercept of 3 on a piece of graph paper.
Now,
Since, James draws a line that has an x-intercept of "-5" and y-intercept of 3 on a piece of graph paper.
Hence, The slope of the line = - 3/5
And, The y - intercept = 3
Thus, The equation of line will be;
⇒ y = - 3/5x + 3
