Subtracting a negative integer is the same as adding a positive integer. Adding a positive integer to any number always makes the answer larger than the original number. Therefore, if you subtract one negative integer from another your answer will be always be *greater* than the integer you started with.
Answer:
5
Step-by-step explanation:
Hi,
find the x- and y-intercepts:
10x + 4y = 20
finding x-intercept when y = 0
10x = 20
x = 2 Pt(2,0) the x intercept
finding y-intercept when x = 0
4y = 20
y = 5 Pt(0,5) the y intercept
Answer:
The answer to your question is the letter C
Step-by-step explanation:
Data
a = 4.5 u
b = 5.8 u
c = 3 u
Process
1.- Calculate the volume of the rectangular prisms
Formula
Volume = a x a x c
Substitution
Volume = 4.5 x 4.5 x 3
Result
Volume = 60.75 u³
But there are two rectangular prism
Total volume = 2 x 60.75
= 121.5 u³
2.- Calculate the volume of the triangles
Formula
Volume = base x width x height
Substitution
Volume = 5.8 x 3 x 4.5
Result
Volume = 78.3 u³
3.- Total volume
Volume = 121.5 + 78.3
= 199.8 u³
Ax + b = r
subtract ax from both sides:-
ax - ax + b = r - ax
b = r - ax (answer)
Answer:
D. X=-3, y=4
Step-by-step explanation:
-2x+3y=18 equation 1
x=-y+1 equation 2
-2(-y+1)+3y=18 replace x value of equation 2 into equation 1
2y-2+3y=18
5y=20
y=4
solve for x by replacing y value into either equation.
x=-y+1
x=-4+1
x=-3
