Answer:
Step-by-step explanation:
2/5 + 3/7 + 1/4 = 28/140 + 60/140 + 35/140 = 123/140
Answer:
a = x and b = 4
Step-by-step explanation:
x^3 - 64 = (x - 4)(x^2 + 4x + 16)
so
a = x and b = 4
Answer: x = 148 degrees
Step-by-step explanation:
This problem makes use of Supplementary Angles. Supplementary Angles states that two angles that make up a line add to 180. Thus, simply use the equation 32 + x = 180
x = 148

Answer:
(1,-1)
(7,12)
(5,-3)
Step-by-step explanation:
we know that
If a ordered pair is a solution of the inequality, then the ordered pair must satisfy the inequality
we have

Verify each case
case 1) we have
(1,-1)
substitute the value of x and the value of y in the inequality and then compare the results

----> is true
therefore
The ordered pair is a solution of the inequality
case 2) we have
(7,12)
substitute the value of x and the value of y in the inequality and then compare the results

----> is true
therefore
The ordered pair is a solution of the inequality
case 3) we have
(-6,-3)
substitute the value of x and the value of y in the inequality and then compare the results

----> is not true
therefore
The ordered pair is not a solution of the inequality
case 4) we have
(0,-2)
substitute the value of x and the value of y in the inequality and then compare the results

----> is not true
therefore
The ordered pair is not a solution of the inequality
case 5) we have
(5,-3)
substitute the value of x and the value of y in the inequality and then compare the results

----> is true
therefore
The ordered pair is a solution of the inequality
The solution id (0, 2). This is because it is where the two lines meet.
