The answer is 4x + 5y.
Here, what needs to be done is to combine like terms.
- 5x + 4y + 3x - 7y - 4x + 8y
- 5x + 3x - 4x + 4y + 8y - 7y
- 4x + 5y
Answer:
A number line going from negative 7 to negative 1. A closed circle is at negative 5. Everything to the right of the circle is shaded.
Step-by-step explanation:
-4.4 ≥ 1.6 x - 3.6
Solving for the value of x,
1.6 x ≤ -4.4 + 3.6
1.6 x ≤ - 0.8
Dividing 1.6 from both sides to know value of x
x ≤ - 0.5
This would be cos^2x, because when you foil out the equation you get 1-sin^2(x).
1-sin^2(x)=cos^2(x)
5:8
X:7
Cross multiply :
= 7(5)=8x
35=8x
Now divide both sides by 8
35/8= x
x= 4.375
Step-by-step explanation:
2(7x +8)=12
2(7x +8)/2 =12/2
7x +8 =6
7x=6-8
7x = -2
x= -2/7
