Use the discriminant to determine all values of k which would result in the graph of
the equation y = x2 + 20x + k not intersecting the x-axis.
Answer:
k > 100
Step-by-step explanation:
y= x²+20x+k
if the graph doesn't intersect the x-axis it means it has no real roots so the discriminat has to be negative so will have imaginary roots
discriminant is
b²-4ac = 20²-4*1*k = 400-4k for this to be negative k has to be more then 100 so will have 400 - a number bigger then 400
k > 100 is the solution
For the function f(x) = (x – 9)7, find f-1(x).

The cost of a pizza varies directly as the square of its radius. If a pizza with a 6 inch radius costs Php 8.00, how much should a pizza with an 11 inch radius cost?
Answer:
An 11 inch radius pizza costs Php 14.63!
Step-by-step explanation:
We have to find the average cost for each inch radius of pizza!
8/6 = 1 1/3
The average cost is Php 1.33
Now we multiply that by 11
1.33 * 11 = 14.63
An 11 inch radius pizza costs Php 14.63
A pizza with a 6 inch radius costs Php 8.00.
A pizza with 11" radius costs Php 26.88.
Let:-
k = constant
c = cost of a pizza
r = radius of pizza
The cost of a pizza varies directly as the square of its radius.
[tex]c[/tex] ∝ [tex]r^{2}[/tex]
[tex]c=kr^{2}[/tex]
Where: c = 8, r = 6
[tex]8=k(6)^{2} \\k=\frac{8}{36} \\\\k=\frac{2}{9}[/tex]
When r = 11 inch
[tex]c=kr^{2}\\c=(\frac{2}{9})(11)^{2}\\c=26.88[/tex]
Therefore, A pizza with 11" radius costs Php 26.88.

What is the best estimate for the value of the expression?
(34/8-16/3)-14/9
Answer:
The best estimate is -2.64
Step-by-step explanation:
To get the estimate value we are rounding all values to the nearest hundredth
You use BOMDAS/PEMDAS to do this expression
(34/8 - 16/3) - 14/9
= 4.25 - 5.33 - 14/9
= 4.25 - 5.33 - 1.56
= -1.08 - 1.56
= -2.64

What is the slope of a line parallel to the line whose equation is 6x-2y=32
Answer:
Write this:
y= -3x + 1
Step-by-step explanation:
Solve the equation:
6x -2y = 32
Subtract 6x from both sides
-2y = -6x +32
divide by negative to on both sides
y = -3x -16
ANSWER:
y = -3x (any number ,negative or positive, except 16)
The slope of the line will be 3.
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation of parallel line is,
⇒ 6x - 2y = 32
Now,
The slope of two parallel lines are always same.
So, We find the slope of the parallel line.
Since, The standard form of equation line is,
⇒ y = mx + c
Where, m is slope of the line.
So, We can change the equation of parallel line in the standard form.
The equation of parallel line is,
⇒ 6x - 2y = 32
Add 2y both side,
⇒ 6x - 2y + 2y = 32 + 2y
⇒ 6x = 32 + 2y
Subtract 32 both side,
⇒ 6x - 32 = 2y
⇒ 2y = 6x - 32
Divide by 2, we get;
⇒ y = 3x - 16
Compare with y = mx + c, we get;
The slope of the line (m) = 3
Thus, The slope of the line will be 3.

Answer:
[tex]y=2x+7[/tex]
Step-by-step explanation:
Given the equation
[tex]y=-\frac{1}{2}x[/tex]
comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is -1/2
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
the slope of the perpendicular line will be: 2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (-2, 3) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = 2 and the point (-2, 3)
[tex]y-3=2\left(x-\left(-2\right)\right)[/tex]
[tex]y-3=2\left(x+2\right)[/tex]
Add 3 to both sides
[tex]y-3+3=2\left(x+2\right)+3[/tex]
[tex]y=2x+7[/tex]
