Find the x-intercept and
the y-intercept from the
following linear equation:
8x + 16y = 32
x-intercept ([?], [ D)
y-intercept (( ], [ 1)
Answers
y-intercept (0, 2)
my work:
to find the intercepts we first have to convert to y = mx + b
y = -1/2x + 2
now we substitute 0 for y or x, first i’m doing the x-intercept.
0 = -1/2x + 2
0 - 2 = -1/2x
-2 = -1/2x
4 = x
now the y-intercept :)
y = -1/2(0) + 2
y = 0 + 2
y = 2
i hope this helped lovely! :)

9. Which of the following is the correct point-slope which of the following is the correct point-slopes equation of the linear relationship
with m = -5 and point (7,9)?
y - 7 = 9(x - 5)
y - 7 = 5(x - 9)
y - 5 = 7(x - 9)
y - 9= -5(x - 7)
Answers
Answer:
y - 7 = 9(x - 5)
Step-by-step explanation:
Answer:
The answer is y - 9= -5(x - 7)
Step-by-step explanation:
hope this helps
y= mx+b
9= -5(7)+b
9 = -35+b
+35 +35
44=b
So the point slope is y=-5x+44
y - 9= -5(x - 7)
y-9=-5x+35
+9 +9
y=-5x+44

y'' = 18x(x³ + 8)⁴(17x³ + 16)
General Formulas and Concepts:
Calculus
Derivative Notation dy/dx
Derivative of a constant is 0.
Basic Power Rule:
f(x) = cxⁿ f’(x) = c·nxⁿ⁻¹Chain Rule: [tex]\frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)[/tex]
Product Rule: [tex]\frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)[/tex]
Step-by-step explanation:
Step 1: Define
y = (x³ + 8)⁶
Step 2: Find 1st Derivative (dy/dx)
Chain Rule [Basic Power]: y' = 6(x³ + 8)⁶⁻¹ · (3x³⁻¹ + 0)Simplify: y' = 6(x³ + 8)⁵ · 3x²Multiply: y' = 18x²(x³ + 8)⁵Step 3: Find 2nd Derivative (d²y/dx²)
Product Rule [Chain/Basic Power]: y'' = 2 · 18x²⁻¹ · (x³ + 8)⁵ + 18x² · 5(x³ + 8)⁵⁻¹ · (3x³⁻¹ + 0)Simplify: y'' = 36x(x³ + 8)⁵ + 90x²(x³ + 8)⁴ · 3x²Multiply: y'' = 36x(x³ + 8)⁵ + 270x⁴(x³ + 8)⁴Factor: y'' = 6x(x³ + 8)⁴[6(x³ + 8) + 45x³]Distribute: y'' = 6x(x³ + 8)⁴[6x³ + 48 + 45x³]Combine like terms: y'' = 6x(x³ + 8)⁴[51x³ + 48]Factor: y'' = 6x(x³ + 8)⁴ · 3(17x³ + 16)Multiply: y'' = 18x(x³ + 8)⁴(17x³ + 16)Answer:
[tex]\frac{d^{2}y}{dx^{2}} = 180x.(x^{3} +8)^{4}[/tex]
Step-by-step explanation:
This question requires use of the chain rule:
[tex]y = (x^{3} + 8)^{6}[/tex]
Let:
[tex]u = x^{3} + 8[/tex]
Then:
[tex]y = u^{6}[/tex]
And:
[tex]\frac{dy}{dx} = \frac{dy}{du}. \frac{du}{dx}\\\\\frac{d^{2}y}{dx^{2} } = \frac{d^{2}y}{du^{2}}. \frac{d^{2}u}{dx^{2}}\\\\\frac{dy}{du} = 6u^{5}\\\\\frac{d^{2}y}{du^{2}} = 30u^{4}\\\\\frac{du}{dx} = 3x^{2}\\\\\frac{d^{2}u}{dx^{2}} = 6x[/tex]
So:
[tex]\frac{dy}{dx} = 6u^{5}.3x^{2}\\\\\frac{dy}{dx} = 18u^{5}x^{2}\\\\[/tex]
And:
[tex]\frac{d^{2}y}{dx^{2}} = 30u^{4}.6x\\\\\frac{d^{2}y}{dx^{2}} = 180u^{4}x[/tex]
Finally, substitute u for its equivalent expression in x:
[tex]\frac{d^{2}y}{dx^{2}} = 180x.(x^{3} +8)^{4}[/tex]

determine if the lines are parallel perpendicular or neither y=-7 and x=2
Answers
Answer:
Perpendicular
Step-by-step explanation:
Because the two lines don't have a "b" value in the equation y=mx+b, we know that both these lines are straight lines either horizontal or vertical. So, if we were to graph these, they would intersect and creat 4 90º angles, making it perpendicular (see graph as well)
