Answer:
y=(1/2)x-2
To graph you can use two points (I will use the x and y intercepts)
Put one point on (4, 0) and (0, -2) and you will get your line
Step-by-step explanation:
A slope of 0.5 is 1/2
in y=mx+b, m is the slope
so now we have: y=(1/2)x+b
we substitute 4 for x and 0 for y
0=1/2(4)+b which simplifies to 0=2+b
so b must be -2
this gives us y=(1/2)x-2
Zero
One
Infinitely many
Answer:
2 = 2 infinitely many
Step-by-step explanation:
cancel out -4y + 4y because that equals 0 then your left with 2=2 meaning infinitely many solutions i checked it with photo math
13y + x - 7y
All rational numbers are integers.
All integers are rational numbers.
All whole numbers are rational numbers.

Answer:
Carla needed 164 inches² wrapping paper to wrap the present.
Step-by-step explanation:
Given : A rectangular prism having length 10 inch , width 3 inch and height 4 inch.
We have to find the length of wrapping paper does Carla need to wrap the present which is in form of given rectangular prism (not including overlap)
The length of wrapping paper needed will be equal to the total surface area of rectangular prism.
total surface area of rectangular prism = 2( lw +wh + hl)
Where l denotes length , w denotes width and h denotes height
Given length = 10 inch ,
width = 3 inch
height = 4 inch.
Substitute, we get,
total surface area of rectangular prism =2 (10× 3 + 3× 4 + 4 × 10 )
total surface area of rectangular prism =2 (30 + 12 + 40)
Total surface area of rectangular prism = 164 inches²
Thus, Carla needed 164 inches² wrapping paper to wrap the present.
