Keith is going to rent a truck for one day. There are two companies he can choose from, and they have the following prices.
Company A charges $120 and allows unlimited mileage.
Company B has an initial fee of $75 and charges an additional $0.90 for every mile driven.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
Answer: m>50
Step-by-step explanation:
Hi, to answer this question we have to write an inequality:
The amount charged by company A (120) must be less (<) than the fixed amount charged by company B (75), plus the product of the cost per mile driven (0.90) and the number of miles driven (m).
120 < 75+ 0.90m
Solving for m:
120-75<0.90m
45<0.90m
45/0.90 <m
50<m
Company A charges less than Company B when m > 50.

O A. x= -2
B. X=-10
O c. x= 2
O D. x= 10
Answer:
I think it's A) x= - 2
Hope this helps..
The solution of the equation is,
⇒ x = - 2
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The equation is,
⇒ 3 (4x + 6) = 9x + 12
Now,
Solve the equation as;
⇒ 3 (4x + 6) = 9x + 12
⇒ 12x + 18 = 9x + 12
⇒ 12x - 9x = 12 - 18
⇒ 3x = - 6
⇒ x = - 6/3
⇒ x = - 2

What is dot plot?A dot plot, also referred to as a dot chart or stripe graph, is a sort of simple histogram-like figure used in statistics for little data sets with values falling into a number of discrete bins.
We have given dot plot in the picture.
As we can see from the dot plot:
Median for career A = 35
Median for career B = 25
And career B dot plot is more spread.
Thus, the statement (A) Centres: Career A has greater median hourly earnings than career (B) and statement (B) Spreads: The hourly earnings for career B are more spread out are correct.

Answer:
Step-by-step explanation:
Well, first of all the shape needs to be a rectangle not a square. And i think you do not understand how coordinates work.
The coordinate (-1, 4). The first number -1 is the number on the x-axis, 4 is the number on the y-axis. Same thing with the other coordinate.
After you put down the two dots, you know that the Perimeter is 24 cm.
P = 2(a + b) = 24 => a+b = 12 => a = 4 => b = 8
The sides are 4 and 8 units long.

On a coordinate plane, a parallelogram has points A (negative 3, 4), B (3, 4), C (1, negative 2), and D (negative 5, negative 2). If a translation of (x, y) → (x + 6, y – 10) is applied to figure ABCD, what are the coordinates of D'? (–5, –2) (1, –12) (4, –15) (–9, –6)
Answer:
1,-12
Step-by-step explanation:
The coordinates of D' after translation is (1, -12).
Option B is the correct answer.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
Parallelogram coordinates:
A = (-3, 4)
B = (3, 4)
C = (1, -2)
D = (-5, -2)
Now,
Translation of (x, y) → (x + 6, y - 10) is applied.
This means,
Parallelogram coordinates:
A' = (-3, 4) → (-3 + 6, 4 - 10) = (3, -6)
B' = (3, 4) → (3 + 6, 4 - 10) = (9, -4)
C' = (1, -2) → (1 + 6, -2 - 10) = (7, -12)
D' = (-5, -2) → (-5 + 6, -2 - 10) = (1, -12)
Thus,
The coordinates of D' is (1, -12).

The answer is not y= -1 + 9
Answer:
y = - x +9
Step-by-step explanation:
slope = (9-0)/(0-9) = - 1
line equation : y= mx + c
find c : 9= - 1*0 +c ....... >> c = 9
y = - x +9 ans
Answer:
y=-x+9Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(9-0)/((0-9))
m=9/(0-9)
m=9/-9
m=-1
y=mx+c
y=-1*x+c
y=-x+c
plug in (9,0) into the equation
0=-1*9+c
0=-9+c
-c=-9
c=9
y=-x+9
