Answer:

For every mile the car is towed, the cost increases by $4.75.

Step-by-step explanation:

The given equation is : y=4.75x+20

Here y is the cost of towing a car if the car is towed x miles.

Lets check each statement:

1. For every mile the car is towed, the cost decreases by $20.

This is false as the cost will increase with each mile and 20 is constant here.

2. For every mile the car is towed, the cost decreases by $4.75.

This is false as the cost will always increase. Cost is directly proportional to miles driven. As miles increases, the cost also increases.

3. For every mile the car is towed, the cost increases by $4.75.

This is true. Here, 20 is constant and 4.75x varies whenever multiplied by a value of 'x'.

Lets check for 2 miles :

y=4.75(2)+20 = $29.5

Lets check for 3 miles :

y=4.75(3)+20 = $34.25

Difference of 34.25-29.50=4.75 dollars

So, this is the true statement.

4. For every mile the car is towed, the cost increases by $20.

This is false as 20 is a constant number in the given equation.

It would be C
y = 4.75x + 20 means
y equals 4.75 times x plus 20
4.75x is the cost of each mile towed
20 is the base number.

some mix up the order to trick you. it's not that hard to guess.

Brainiest to whoever right
Anna35 [415]

Answer:

since M lies between point A and B , we came to know that,

M(4,6) =(x,y)

A(-2,-1)=(x1 ,y1)

B( _, _ )=(x2,y2)

Now using mid point formula,

x=x1×x2÷2 y=y1+y2÷2

so, point B is (10,13)

Select the correct answer.
Yuliya22 [10]

Answer: B is your correct answer.

Step-by-step explanation: If she has already made $95.00 from selling jam and made $24.00 from demonstrations you add those together to get $119. Then you subtract $119.00 from $450.00 and you'll have $331.00 left to make. Finally you divide $331.00 by $5.00 (cost of jam) and you'll find that you have to sell 66 more jars of jam.

What is the volume of the cone ?
sleet_krkn [62]

{210in}^{3}

This is found by the volume of a cone formula

b \times  \frac{h}{3}

Where b is the base and h is the height

45 \times  \frac{14}{3}   =  \frac{630}{210}  = 210

A chili recipe calls for 2 pounds of ground pork and 3.5 pounds of ground beef. The cost of ground beef per pound is $0.20 less
dmitriy555 [2]

Answer: \$1.75\ \text{per pound}

Step-by-step explanation:

Given

The recipe calls for 2 Pounds of ground pork and 3.5 pounds of ground beef

Suppose x is the cost of ground pork

So, the cost of ground beef is 2x-0.2

The total cost of meat is \$15.05

The total cost can also be written as

\Rightarrow 2\times x+3.5\times (2x-0.2)=15.05\\\Rightarrow 2x+7x-0.7=15.05\\\Rightarrow 9x=15.75\\\Rightarrow x=\frac{15.75}{9}=\$1.75\ \text{per pound}

So, the cost of ground pork is \$1.75\ \text{per pound}

Given that g(x)=3x²-5x+7 find the following: <br> g(-x)
AURORKA [14]
G(x) = 3x² - 5x + 7
g(-x) = -(3x² - 5x + 7)
g(-x) = -3x² + 5x - 7

This equation cannot be solved because of a few reasons,

1. This equation didn't show that it equals to 0.
2. Even if it equals to zero, square root of a negative number cannot be solved.
(I will show you what I mean)

-3x² + 5x - 7
is the same as
3x² - 5x + 7
by shifting the equation,

for example,
1 - 3 = -2
shifting other side
2 = -1 + 3

using 3x² - 5x + 7 to solve,

Solve\ using\ the\ formular\ \ \boxed{ x= { \frac{-b \pm \sqrt{b^2-4ac} }{2a} } }
a = 3
b = -5
c = 7
x= { \frac {-(-5) \pm \sqrt{ (-5)^2-4(3)(7) } }{2(3)} }
x= { \frac {5 \pm \sqrt{-59} }{6} }

∴This equation cannot be solved.
