To find the slope use the formula Y2-Y1 --------- X2-X1 (-1,-4) (1,4) 4- -4 = 8 ------------- 1- -1 = 2 8/2=4 This will be your slope Y=4x Now we must figure out the y-intercept using the formula Y-y1=slope(x-x1) Y- -4= 4(x- -1) Y+4= 4x + 4 The 4 distributes to the x and -1 Y=4x +4 -4 Y= 4x This is your answer in slope intercept form. P.S if you have a number minus a negative number it makes it a positive number

Katherine has $140 in the bank and is saving $6 per week. Abbie has $462 in the bank, but is spending at a rate of $10 per week.
AveGali [126]
Let x be the number of weeks for this financial situation. The amount that Katherine will have at the end of x weeks is 140 + 6x. On the other hand, with the spending that she is doing, Abbie will have 462 - 10x after x weeks. Equating the two,
                                     140 + 6x = 462 - 10x
Thus, the answer is letter B.

Sam is fencing in his property. The length is 12 feet less than twice the width. If the total amount of fence needed is 216 feet
DaniilM [7]

Answer:

L = 68 ft

Step-by-step explanation:

To find the perimeter of something you need to add up all the sides

In this case I am assuming Sam's property is a square/rectangle

  • Which means the formula for the perimeter is P = 2L + 2W

If L = 2W - 12 and P = 216, we can use these values and plug them into our perimeter equation to solve for w and then solve for l

  • 216 = 2(2W -12) + 2W → ditributing the 2 to the (2w - 12) gives us
  • 216 = 4W - 24 + 2W → combing like terms gives us
  • 216 = 6W - 24 → adding 24 to both sides gives us
  • 240 = 6W → dividing both sides by 6 gives us
  • 40 ft = W

With the width being solved, we can now plug that value into our length equation

  • L = 2(40) - 12 → distributing the 2 to the 40 gives us
  • L = 80 - 12 → combing like terms give us
  • L = 68 ft

How do you find the volume of a trapezoid
Naya [18.7K]
If the prism length is L, trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2.

" In other words, multiply together the length, height, and average of A and B."
