Answer:
1st one a^-1 , 2nd one a^b/a^c , 3rd one a^c/b^c
The answer is B)
x2+2x−3=0
Factor left side of equation.
(x−1)(x+3)=0
Set factors equal to 0.
x−1=0 or x+3=0
x=1
or
x=−3
This an isosceles right triangle. The sides opposed to the angle 45° are congruent. Let x be this side==> x²+x² =(7√2)² (Pythagoras)
2x² = 49(2) ==> 2x²= 98 ==> x²=49 & x=7
Answer:
The answer to your question is Advance = $35 and same-day = $40
Step-by-step explanation:
Advanced = a
Same-day = s
Equations
a + s = 75 ----- (I)
20a + 35s = 2100 ----- (II)
Process
1.- Solve the equations by elimination.
Multiply equation I by -20
-20a - 20s = -1500
20a + 35s = 2100
Simplify
0 + 15s = 600
Solve for s s = 600/15
s = $ 40
Substitute "s" in equation I to find "a"
a + 40 = 75
Solve for a
a = 75 - 40
a = 35
Answer:
it is not function
Step-by-step explanation:
because,
first of all,what do mean function
A function is a relation in which each element of the domain corresponds to exactly one
element of the range.
based on this description
Since the domain element 1 is assigned to two different values in the range, -1 and 1, so that it is
not a function
