ummmmm i think it is not.......
Step-by-step explanation:
but please wait for somebody else to answer first!! i would hate for you to get it wrong.
The solution to the inequalities 3x + 5 < 6x + 8 and 4x + 3 < 7x + 5 is x > -1 and x > -2/3 respectively
<h3>Inequality</h3>
Inequality signs are;
- Greater than >
- Less than <
- Equal to =
- Less than equal to ≤
- Greater than equal to ≥
3x + 5 < 6x + 8
3x - 6x < 8 - 5
-3x < 3
x > 3/-3
The inequality sign is flipped from < to greater than because of the division with negative value.
x > -1
2. 4x + 3 < 7x + 5
4x - 7x < 5 - 3
-3x < 2
The inequality sign is flipped from < to greater than because of the division with negative value.
x > -2/3

Answer:
B=1 M=6 D=3
Step-by-step explanation:
the equations are 4M+4D+2B=38
M+D+B=10
2D=M
step two: 4M+4D+2B=38 (multiply 2nd equation by -4)
-4M-4D-4B=-40
4M AND 4D cancels out and your left with -2B=-2 B=1
then you take the first equation and subsitute the third equation for M
step three: M+D+1 =10 (SUBSITUTE B WITH 1)
M+D=9
STEP FOUR: take the last equation (M+D=9) and subsitute 2D=M
2D+D=9
3D=9
D=3
subsitute D=3 into 2D=M so you get 2(3)=M M=6
DOUBLE CHECK USE THE SECOND EQUATION
M+D+B=1-
6+3+1=10
(9-(-3)/(8-(-4)) 12/12=1. Slope =1
