E^7 = x +3
e^7 -3 = x
(Use Calc)
Answer:
A.
Step-by-step explanation:
you have to find the discriminant
b²-4ac for each equation
if discriminant < 0 no real solutions because will be negative under the squareroot whhan you try to find the roots
if discriminant = 0 there is only one solution
if discriminant > 0 two real solutions
for your given problems
A. discriminant =(-2)²-4*2*15 will be negative
Step-by-step explanation:
Rational numbers
7/8, square root of 25
(0.35x + 0.14 * 18) / y = 0.23
x + 18 = y
