Answer:
x = 4
y = -3
Step-by-step explanation:
2x + 4y = -4
x + 2y = -2 ---------(1)
3x + 5y = -3 ----------(2)
Equation (1) multiplied by 3 then subtracted from equation (2),
(3x + 5y) - 3(x + 2y) = -3 + 6
-y = 3
y = -3
From equation (1)
x + 2(-3) = -2
x - 6 = -2
x = 6 - 2
x = 4
(Answer 2,770) (estimation: 3,000)
3 3/5. - 4 1/2
find a common denominator
3/ 5 = 6/ 10.
1/2. = 5/10
3 6/10. - 4 5/10
- 1 1/10
Step-by-step explanation:
The two triangles are similar so
BC=BC
AB=AB
AC=AC
1.)5z=20 (÷b.s by 5)
z=4
2.)8=2x+2
8-2=2x
6=2x (÷b.s by 2)
x=3
3.)3y-3=15
3y=15+3
3y=18. (÷ b.s by 3)
y=6
Answer:
The inequality representing the shaded area is y < 3 - 2.5·x
Step-by-step explanation:
The given equation of the graph is 5·x + 2·y = 6
Therefore, we have;
2·y = 6 - 5·x
y = 6/2 - 5/2·x
y = 3 - 2.5·x
Given that the graph is represented by a shaded region on the left and lower side of a broken line, the inequality relationship for the graph is that of a lesser than area inequality with a symbol of < and the inequality for the graph can be represented as follows,
y < 3 - 2.5·x.
