1 answer:
kirill [66]2 years ago
8 0

Answer:

Graph 1 ➡ y = 1/5 x + 3

Graph 2 ➡ y = 3x

Graph 3 ➡ y = -3x + 5

Graph 4 ➡ y = 1/3 x + 5

Step-by-step explanation:

Remember that slope is basically rise/run, where rise is up and down movement and run is left and right movement.

Also remember the formula for slope is y=mx+b, where m is slope and b is y-intercept. Additionally if y-intercept is 0 you don't write it.

Hope this helps :)

Please help!!!<br> I need help finding the answer.
iogann1982 [59]

Answer:

2nd option

Step-by-step explanation:

The shaded area = outside area - inner area

                           = x² - (x - 6)² ← expand using FOIL

                         = x² - (x² - 12x + 36) ← distribute parenthesis by - 1

                        = x² - x² + 12x - 36 ← collect like terms

                        = 12x - 36

Let f(x)=x^3-x-1
alexira [117]
f(x) = x^3 - x - 1

To find the gradient of the tangent, we must first differentiate the function.

f'(x) = \frac{d}{dx}(x^3 - x - 1) = 3x^2 - 1

The gradient at x = 0 is given by evaluating f'(0).

f'(0) = 3(0)^2 - 1 = -1

The derivative of the function at this point is negative, which tells us <em>the function is decreasing at that point</em>.

The tangent to the line is a straight line, so we will have a linear equation of the form y = mx + c. We know the gradient, m, is equal to -1, so

y = -x + c

Now we need to substitute a point on the tangent into this equation to find c. We know a point when x = 0 lies on here. To find the y-coordinate of this point we need to evaluate f(0).

f(0) = (0)^3 - (0) - 1 = -1

So the point (0, -1) lies on the tangent. Substituting into the tangent equation:

y = -x + c \\\\ -1 = -(0) + c \\\\ -1 = c \\\\ \text{Equation of tangent is } \boxed{y = -x - 1}

Gennadij [26K]

Answer:

Right angled triangle

Step-by-step explanation:

This is because the square root of the sum of the squares of 7 and 24 is 25 ( Pythagoras theorem) . This only works for right angled triangle.
