Large Cheese Pizza $14.85

1 answer:

7 0

2. $16.90 + $5.99 = $22.89
22.89-5= $17.89 The answer is reasonable

3. 14.85 x 3= $44.55 this is the total cost
to find the tax, multiply 44.55 times 0.2
The answer is not reasonable, the tip should be $8.91

Plz help me this question plz plz help plz help me all four of them plzzzz

garik1379 [7]

Answer:

10) The equation of a line parallel to $y=-3$ passing through the coordinate (2,6) is $y=6$

11) The equation of a line perpendicular to $y=-3$ passing through the coordinate (2,6) is $x=6$

12) The equation of a line parallel to $x=4$ passing through the coordinate (-2,3) is $x=-2$

13) The equation of a line perpendicular to $x=4$ passing through the coordinate (-2,3) is $y=3$

Step-by-step explanation:

For any line parallel to X-axis the equation we have

$y=a$

where a is the y coordinate.

∴ The equation of a line parallel to $y=-3$ passing through the coordinate (2,6) is $y=6$

For any line parallel to Y-axis the equation we have

$x=b$

Where b is the x coordinate.

∴ The equation of a line parallel to $x=4$ passing through the coordinate (-2,3) is $x=-2$

For any line perpendicular to X-axis is parallel to Y axis therefore the equation we have

$x=b$

∴ The equation of a line perpendicular to $y=-3$ passing through the coordinate (2,6) is $x=6$

For any line perpendicular to Y-axis is parallel to X axis therefore the equation we have

$y=a$

∴ The equation of a line perpendicular to $x=4$ passing through the coordinate (-2,3) is $y=3$

What is the answer? trying hard here

kumpel [21]

You basically have to use the quadratic formula to solve this since there are no factors of - 9 which add to give 6.
$x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac} }{2a}$
Then you use
$a {x}^{2} + bx + \: c$
To find which numbers will go into what place inside the quadratic equation.

So a = 1 (because x is alone)
b = 6
c = -9

Then you solve it. I've included a picture of how I did it and I got the answer x=-3+-3sqrt2

Which linear system of equations does the matrix represent <br><br> M=[874]<br> [205]

Finger [1]

Answer:

This Matrix M=[874]

[205] represents a quadratic equation in one variable having two solution.

For example

Consider the Quadratic equation

$x^2 - 3 x + 2=0$

⇒(x - 1)(x-2) =0

⇒( x- 1)=0 ∧ (x-2)=0

x=1 ∧ x=2

So we can write this solution in matrix as

[x] =[1]

[2]

This is a quadratic equation in M .
