Mrs. Nevin is making a costume for a school play. She needs a piece of fabric that is greater than 1/2 of a yard but less than 5

Answer:

4/7 yards

Step-by-step explanation:

4/7 yards = 0.571

3/7 yards = 0.429

2/4 yards = 0.5

0.5 < 0.571 < 0.625

From the options, only 4/7 yards satisfies the condition :

Please hurry!!! Chose the equation below that represents the line that passes through the point (7,-2) and has a slope of -3
Varvara68 [4.7K]

Answer:

y + 2 = -3(x - 7)

Step-by-step explanation:

Write the equation using the point slope form y - y_1 = m(x-x_1). Substitute m = -3 and (7,-2).

y --2 = -3(x-7)\\y + 2 = -3(x-7)\\y +2 = -3x +21\\y = -3x +19
