Answer: Joey's answer should be a square.
Step-by-step explanation: Given that Joey is asked to name a quadrilateral which is also a rhombus. We are to find Joey's answer.
Rhombus : a quadrilateral having all the four sides equal and diagonals bisect each other perpendicularly.
We know that the only quadrilateral having four equal sides and diagonals bisecting each other perpendicularly is a SQUARE.
Also, a square has all angles as right-angles in addition.
Therefore, Joey's answer should be a square.
-98.6/3.8=-25.94 because if you line the decimals up and then add them you will get -25.94
-98.60
+ 3.80
-25.94
Therefore, the intervals that must be tested are
x<3,3 5.
The solution set for the quadratic inequality is:
Answer:
Option 4: (3,5)
Step-by-step explanation:
(x - 3)(x - 5) < 0
Therefore, the intervals that must be tested are x < 3 , 3<x<5 and x>5
Test of the interval x<3⇒ Let x = 0 ⇒ (-3)(-5) = 15 > 0
Test of the interval 3<x<5 ⇒ Let x = 4 ⇒ (4-3)(4-5) = (1)(-1) = -1 < 0
Test of the interval x>5⇒ Let x = 6 ⇒ (6-3)(6-5) = (3)(1) = 3 > 0
So, the solution set for the quadratic inequality is the interval 3<x<5
Or x ∈ (3,5)
See the attached figure.
The answer is option 4
Answer:
1. (3,5) 2. b and c
Step-by-step explanation:
Just took it and got it correct
1. 4x + 2 = -10
2. 7x + 12 = -9
Answer:
1. x = -3
2. x = -3
Step-by-step explanation:
1.
First subtract 2.
4x = -12
Divide by 4.
x = -3
2.
Subtract 12 from both sides.
7x = -21
Divide by 7
x = -3
Answer:
1. -3
2. -3
Step-by-step explanation:
x = 1
x = 2
x = 5
x = 6
Answer: x = 6
Step-by-step explanation:
Let's solve your equation step-by-step.
81x=27x+2
Solve Exponent.
81x=27x+2
log(81x)=log(27x+2)(Take log of both sides)
x*(log(81))=(x+2)*(log(27))
x=(
log(27)
log(81)
)*(x+2)
x=0.75*(x+2)
x=0.75x+1.5(Simplify both sides of the equation)
x−0.75x=0.75x+1.5−0.75x(Subtract 0.75x from both sides)
0.25x=1.5
0.25x
0.25
=
1.5
0.25
(Divide both sides by 0.25)
x=6
The answer is 400.
There are 4 hundreds, 0 tens and 0 ones
4 hundred because it only has 4 hundreds with no other numbers
