Answer:
-14
Step-by-step explanation:
Follow PEMDAS, then the left -> right rule.
PEMDAS =
Parenthesis
Exponent (& roots)

Subtraction
First, multiply 6 with -2:
6 x -2 = -12
Next, add 1, then subtract 3.
-12 + 1 = -11
-11 - 3 = -14
-14 is your answer.

Answer:
<em>128</em>
Step-by-step explanation:
<em>Method A.</em>
The volume of the prism is 2 cubic units.
Each cube has side length of 1/4 unit.
The volume of each cube is (1/4)^3 cubic unit.
The volume of each cube is 1/64 cubic unit.
To find the number of cubes that fit in the prism, we divide the volume of the prism by the volume of one cube.
(2 cubic units)/(1/64 cubic units) =
= 2/(1/64)
= 2 * 64
= 128
<em>Method B.</em>
Imagine that the prism has side lengths 1 unit, 1 unit, and 2 units (which does result in a 2 cubic unit volume.) Since each cube has side length 1/4 unit, then you can fit 4 cubes by 4 cubes by 8 cubes in the prism. Then the number of cubes is: 4 * 4 * 8 = 128

Answer:
First question: (0, 1) (-4, 0)
Step-by-step explanation:
FIRST QUESTION:
y=3x+1
y=x-7
In the first equation of the first question, (y=3x+1) the 3 represents the slope and the 1 represents the y-intercept. Therefore, your first coordinate is (0, 1).
To figure out the second coordinate, do this:
Substitute y for x-7
x-7=3x+1
Combine like terms
x=3x+8
-3x+x=8
-2x=8
Divide the entire equation by -2
x=-4
Therefore, your second coordinate is (-4, 0).
SECOND QUESTION:
I am really sorry, I can't see the second question very well. It's a little too blurry and I have bad eyesight.
Hope this helps a little.
