300 is the answer
(I hope it is correct)
To make this table, pick any value you want for x, then substitute it an solve for y.
For example, if you choose x=1, then
y=-2/3(1)-1
y=-2/3-3/3
y=-5/3
To do a three part table quickly, I like to use -1, 0, and 1 for the value of x, since -1 and 1 will not change the values, only the sign for -1, and 0 eliminates the m section of the equation.
I hope this helps !!!!
Answer:1/3?
Step-by-step explanation: sorry I don’t wanna take ur points just be more specific in the comments pls
Answer:
Procedure in option C only works.
Step-by-step explanation:
We have to select the process in which Mrs. Smith can help her to work 30 divided by 3.
(A) (27 divided by 9) + (9 divided by 3) = 3 + 3 = 6
But (30 ÷ 3) = 10 ≠ 6
(B) (24 divided by 4) + (4 divided by 4) = 6 + 1 = 7 ≠ 10
(C) (21 divided by 3) + (9 divided by 3) = 7 + 3 = 10
(D) (20 divided by 4) + (10 divided by 4) = 5 + 2.5 = 7.5 ≠ 10
So, procedure in option C only works. (Answer)
Again, we can prove the procedure in the following way:
{Which is the distributive property of division}
Answer:
length: 14.2 ft; width 4.2 ft.
Step-by-step explanation:
Let x represent the length of the rectangle in feet. Then x-10 represents the width, and the area is ...
area = length×width
60 = x(x -10) . . . . . substitute the expressions for area, length, width
60 = x² -10x
85 = x² -10x +25 . . . . add (10/2)² to complete the square
85 = (x -5)² . . . . . . . . . rewrite as a square
√85 = x -5 . . . . . . . . . take the square root. Only the positive root is useful for this problem
x = 5 + √85 ≈ 14.2
x-10 = 4.2
The length and width of the rectangle are 14.2 ft and 4.2 ft.
