Answer:
y^3 - 9y^2 + 26y - 29
Step-by-step explanation:
y - 4[y - 3(y - 2)] - 5
I'm going to separate it into parts
(y - 3)(y - 2)
y^2 - 5y + 6
(y - 4)(y^2 - 5y + 6)
y^3 - 5y^2 + 6y - 4y^2 + 20y - 24
y^3 - 9y^2 + 26y - 24
y^3 - 9y^2 + 26y - 24 - 5
y^3 - 9y^2 + 26y - 29
Area of a triangle = (h × b) ÷ 2, where h is height and b is the base.
7.1 × 28 = 198.8
198.8 ÷ 2 = 99.4
The area of this triangle is 99.4 yd²
Answer:
The x-value is between 2 and 3, and the y-value is between –4 and –5.
Step-by-step explanation:
The system of equations y = (1/4)x - 5 and y = -(1/2)x - 3.
The solution of the equation is the point of intersection of the two lines, from the graph, the intersection of the red and blue lines which represent the equation of the lines has an x-value is between 2 and 3, and the y-value is between –4 and –5.
Also the solution of the equation can be solved by solving the two equations simultaneously:
y = (1/4)x - 5 . . . 1)
y = -(1/2)x - 3 . . . 2)
Subtracting equation 2 from 1:
0 = (3/4)x - 2
(3/4)x = 2
x = 2 × 4/3
x = 8/3 = 2.67
x = 2.67
To find y put x = 2.67 in equation 1:
y = (1/4)(8/3) - 5
y = 8/12 - 5
y = -13/3
y = -4.33
Answer:
x = 30
Step-by-step explanation:
Box a = 12m^3
Box b =12m^3 times 5^3, so box b is 12 times 125 or 1500
At least I believe that this is correct
