Answer:

Answer:

y - intercept = - 18

Step-by-step explanation:

To find the y-intercept of the line

y + 4 = - 4 ( x + 3.5 ) ,

We can transpose the equation into the y = mx + b formula where b = y - intercept.

y + 4 = - 4 ( x + 3.5 )

y + 4 = ( - 4x ) + ( - 14 )

y + 4 = - 4x - 14

y = - 4x - 14 - 4

y = - 4x - 18

b = - 18

Therefore:

y - intercept = - 18

Find the length of each leg. 7 ft 7√2 ft √7 ft 7√2 ft 2 Please help
Thank you

Answer:

$(7√(2) )/(2)$

Step-by-step explanation:

The 2 legs are congruent.

Let the leg be x, then using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, thus

x² + x² = 7², that is

2x² = 49 ( divide both sides by 2 )

x² = $(49)/(2)$ ( take the square root of both sides )

x = $\sqrt{(49)/(2) }$

= $(7)/(√(2) )$ × $(√(2) )/(√(2) )$

= $(7√(2) )/(2)$

How do you find the x-coordinate of the vertex of a parabola if you only have the equation

Answers

Answer and Explanation:

The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k.
