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.

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°

Find the value of x. Your answer must be exact.
х
45° 18
Answer:
x = 63
Step-by-step explanation:
Simplifying
x + -18 = 45
Reorder the terms:
-18 + x = 45
Solving
-18 + x = 45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + x = 45 + 18
Combine like terms: -18 + 18 = 0
0 + x = 45 + 18
x = 45 + 18
Combine like terms: 45 + 18 = 63
x = 63
Simplifying
x = 63

Solve 7+2x over 3 = 5
Please and thank you! x
Answer:
x = 4
Step-by-step explanation:
(7 + 2x) / 3 = 5
Cross product
7 + 2x = 5 * 3
7 + 2x = 15
Subtract 7 from both sides
2x = 15 - 7
2x = 8
Divide both sides by 2
x = 8/2
x = 4

3x + x - 7 = 10
What does x=
First you add 3x+x because they are like terms.
3x+x-7=10
Your New Simplified Equation:
4x-7=10
Now, you have to take out the -7 by adding a positive 7. Also you have to add +7 on the other side so add 7 to 10.
Your New Simplified Equation:
4x=17 Now, you divide both sides by 4.
Your New Simplified Equation:
x= 17/4 So, that's your answer :)

Which inequality describes all the solutions to -5x + 6 -9
B. x 4
Answer:
-5x-3
Step-by-step explanation:
-5x+6-9=-5x-3
The inequality that describes all the solutions to the given inequality expression is x > 4
Given the inequality expression -5x + 6 < 2(-3 − x)
Expand the right-hand side of the ineqality
-5x + 6 < -6 - 2x
Collect the like terms
-5x + 2x < -6 - 6
-3x < -12
Divide both sides by -3
-3x/-3 > -12/-3
x > 4
Hence the inequality that describes all the solutions to the given inequality expression is x > 4
