Answer:
I would love to help, but where is the equations?
Answer:
7.5
Step-by-step explanation:
2/3 x 7.5 = 5
5 - 1 = 4
Answer:
The solution of the system is at point (1,6) and (7,0).
Step-by-step explanation:
Given : System of equation 
and 
To find : Solve the system of equation?
Solution :
We solve the equation graphically as the intersection points give you the solution of the system.
The equation given is one linear and one parabolic.
(1) is a linear equation in red line passes through (0,7) and (7,0).
(2) is a parabolic equation in blue line passes through (-1,0) and (7,0)
The intersection point of the equations are (1,6) and (7,0).
<u>Refer the attached figure below.</u>
Therefore, The solution of the system is at point (1,6) and (7,0).
The solution interval for x is x ∈ (-1/4 , ∞)
An inequality shows the relationship of a non-equal comparison between two numbers or mathematical expressions.
Here, we are given two inequalities
x/4 > -1 and -4x - 4 < -3
Let us take the first equation
x/4 > -1
⇒ x > 4(-1)
x > -4
Now, the second equation
-4x - 4 < -3
-4x < -3 + 4
-4x < 1
Now since we are dividing both sides by a negative number, that is 4, the sign of the inequality will be reversed,
x > 1/-4
x > -1/4
Thus, we get x > -4 and x > -1/4
This means that all values of x greater than -1/4 will satisfy.
Thus, x ∈ (-1/4 , ∞)
