Peter says there are two distances for which he and Maria charge the same amount. To prove Peter is not correct, Maria graphs a line for her delivery charges and a line for Peter’s delivery charges. Each line represents the relationship between the amount (y), in dollars, each person charges for a delivery and the distance (x), in miles, each drives for the delivery. Without showing the graph, explain how Maria’s graph of the two lines proves Peter is not correct.

Write the word sentence as an equation. Then solve.
10 more than a number c is 3.
Answer:
10+c=3
Step-by-step explanation:
to solve this you would then subtract 10 from both sides, to get c by itself.
3-10= -7
Your answer would be -7 and the equation would be 10+c=3.
Solve: x3 = 27
A) X = 3
B) X= 3 and x = -3
C) X = 9
D) X = 9 and x = -9
Answer:
C
Step-by-step explanation:
27/3=9
Just do cube root of 27.
x has to equal 3 because -3 cubed is -27, 9 cubed is 729, and -9 cubed is -729.
X = 3, The answer is choice A.

Answer:
[tex]x=\frac{-9\pm3\sqrt{5} }{2}[/tex]
Step-by-step explanation:
Standard Form: ax² + bx + c = 0
Quadratic Formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]
Step 1: Write equation
x² + 9x + 9 = 0
Since we cannot factor the expression, we will have to use the quadratic formula.
Step 2: Define
a = 1
b = 9
c = 9
Step 3: Solve for x
Substitute: [tex]x=\frac{-9\pm\sqrt{9^2-4(1)(9)} }{2(1)}[/tex]Evaluate: [tex]x=\frac{-9\pm\sqrt{81-36} }{2}[/tex]Evaluate: [tex]x=\frac{-9\pm\sqrt{45} }{2}[/tex]Simplify: [tex]x=\frac{-9\pm3\sqrt{5} }{2}[/tex]Answer:
X1= -9-3[tex]\sqrt5[/tex] over 2 X2= -9+3[tex]\sqrt5[/tex] over 2 (draw a line under the -9 to the 5
and put a 2 under like a fraction
i cant get the line all the way
across on here sorry
Step by step explanation:
x= -9 [tex]\sqrt9^2 -4x1x9[/tex] Over (draw a line under that) Put all that under sq root
2 x 1 also
x= -9+ [tex]\sqrt81-36[/tex] Over 2

You have a party of four that requested separate checks. The table's checks were for $35, $28, 942, and $22. With tips
you collect $144 from the table. Tips of over 15% indicate the service is good. Did tipping indicate good service at this table?
a) Yes
b)No
Answer:
No
Step-by-step explanation:
Answer: no
The total bill amounts up to $1,027.00. Fifteen percent of $1,027.00 is $154.05. The waiter received $144.00. Therefore she did not indicate good service.

Which of the relations below is a function?

{(2,3), (3,4), (5,1), (6,2), (3,3)}
{(2,3), (3,4), (5,1), (6,2), (7,3)}
Answer:
{(2,3), (3,4), (5,1), (6,2), (7,3)}
Step-by-step explanation:
A relation may or may not represent a function.
The relation that is a function is (c) {(2,3), (3,4), (5,1), (6,2), (7,3)}
Relations and functions
For a relation to be considered a function, then the x values must point to different y-values.
The above condition is true for the relation (3).
This is so because all x values in this relation point to different y-values.
Hence, the relation that is a function is (c) {(2,3), (3,4), (5,1), (6,2), (7,3)}
