Mixed numbers are a mix of a whole number and a fraction
a easy one is
1 and 1/4+1 and 3/4
1 and 1/2 +1 and 1/2
1 and 9/10 and 1 and 1/10
etc
Answer:
91
Step-by-step explanation:
for a 2-digit number the tens digit (x) is 8 more than the ones digit (y) and no number is zero
=> x = y+8
x < 10
y > 0
y = 1 and x = 1 + 8 =9
the 2-digit is 91
Answer:
Θ = 46°
Step-by-step explanation:
the angle between a tangent and a radius at the point of contact is 90° , so
∠ ABO = 90°
since OB = OD ( radii of circle ) then Δ BOD is isosceles and
∠ OBD = ∠ ODB = 22°
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ AOB is an exterior angle of the triangle , then
∠ AOB = 22° + 22° = 44°
the sum of the 3 angles in Δ AOB = 180° , then
Θ + 44° + 90° = 180°
Θ + 134° = 180° ( subtract 134° from both sides )
Θ = 46°
Answer:
The table can be filled as shown below.
Step-by-step explanation:
The first function is
Put different values of x and find values of f(x).
For x=-2
For x=-1
Similarly for x=0,1,2 the value of f(x) are 8,12,16 respectively.
The second function is
For x= -6
For x= -3
Similarly for x=0,3,6 the value of f(x) are 8,10,12 respectively.
The third function is
For x= 2
For x= 3
Similarly for x=4,5,6 the value of f(x) are 32,132,632 respectively.
The fourth function is
For x=-4
For x=-3
Similarly for x=-2,-1,0 the value of f(x) are 11,-1,-4 respectively.
Answer:
Step-by-step explanation:
hello :
2x²+x-1=2 means : 2x²+x-3=0
a=2 b= 1 c= -3
the solutios are : x1 and x2 when the product is : x1×x2 = c/a
let x1 = -3/2 you have : (-3/2)×x2 = -3/2 so x2 = (-3/2)/(-3/2) = 1
The solutions to the equation 2x²+x-1=2 are x=-3/2 or x= 1
