Given a quadratic equation px^2 + 8x + 2 does not have real roots. Determine the range of the values of p.
[4 marks]
Step-by-step explanation:
For a quadratic equation to have no real roots, the discriminant b² - 4ac must be negative.
For px² + 8x + 2 = 0,
We have a = p, b = 8 and c = 2.
=> (8)² - 4(p)(2) < 0
=> 64 - 8p < 0
=> 8p > 64
=> p > 8
Hence the range for p is p > 8.

The sum of two numbers is 25. Twice the first number minus the second is 6. Find the numbers.
Answer:
Step-by-step explanation:
x + y = 25
2x - y = 6 Solve for y in this the second equation. Add y to both sides
2x = 6 + y The ys on the left cancel. Subtract 6 from both sides.
2x - 6 = y
Put this value of y into the first equation
x + y = 25
x + 2x - 6 = 25 Combine on the left
3x - 6 = 25 Add 6 to both sides.
3x = 25 + 6 Combine the right
3x = 31 Divide by 3
x = 31 / 3
x = 10.333333
x + y = 25
10.33333 + y = 25 Subtract 10.33333
y = 25 - 10.333333
y = 14.666666
x + y = 25
10.33333 + 14.66666
25 approximately.
2x - y = 6
2*10.33333 - 14.66666
20.66666 - 14.66666
6
You should note that those numbers are repeating decimals
2x - 6 = y

y=x+4
2x+3y=17
SOLVE USING SUBSITUTION
Show work
Answer:
( 1, 5 )
x = 1
y = 1
Step-by-step explanation:
y = x + 4
2x + 3y = 17
Since they gave us the value of "y" we can use that and substitute it into the equation to find what "x" is.
2x + 3y = 17
2x + 3 ( x + 4 ) = 17
Distributive Property
2x + 3 * x + 3 * 4 = 17
2x + 3x + 12 = 17
Combine Like Terms ( 2x and 3x)
5x + 12 = 17
Subtract 12 on both sides of the equation
5x + 12 - 12 = 17 - 12
5x = 5
Divide by 5 on both sides to isolate the variable
5x/5 = 5/5
x = 1
Now that we have what "x" is, we can substitute that into one of the equations to get the value of "y"
y = x + 4
y = 1 + 4
y = 5
x = 1
y = 5
( x, y )
( 1, 5 )

LIFE
I wonder what it's all about, and why
We suffer so, when little things go wrong?
We make our life a struggle,
When life should be a song.
Our troubles break and drench us,
Like spray on the cleaving prow
Of some trim Gloucester schooner.
As it dips in a graceful bow.
Our troubles break and drench us
But like that cleaving prow,
The wind will fan and drys us.
And we'll watch come other bow.
But why does sorrow drench us
When our fellow passes on?
We just exchanged life's dreary dirge
For an eternal life of song.
What is the inborn human trait
That frowns on a life of song?
That makes us weep at the journey's end,
When the journey was oft-times wrong?
Weep when we reach the door
That opens to let us in,
And brings to us eternal peace.
As it closes again in sin.
Millions have gone before us,
And millions will come behind.
So why do we fight
At a fate both wise and kind.
We hang into a jaded life
A life full of sorrow and pain.
A life that warps and breaks us,
And we try to run through it again and again.

I rlly need help and the operation bby plssssss help me
Answer:
∠ AFE = 35°
Step-by-step explanation:
∠ EFD = ∠ BFC = 55° ( vertically opposite angles )
Since BD is a straight line , then
∠ EFD + ∠ AFE + AFB = 180°, that is
55° + ∠ AFE + 90° = 180
∠ AFE + 145° = 180° ( subtract 145° from both sides )
∠ AFE = 35°
