for every hour it goes down by 5 and you have five hours so its

5+5+5+5+5

so basically its 5×5 and that equals 25

Answer:

x = - 2.5, 1

Step-by-step explanation:

In the given figure, JM and JK are the tangents drawn from the external point J to the [tex] \odot[/tex] L, Points K and M are points of tangency.

Since, tangents drawn from external point to a circle are congruent.

[tex]\therefore JM = JK\\\therefore 2x^2 +3x - 2 = 3\\\therefore 2x^2 +3x - 2 -3=0\\\therefore 2x^2 +3x - 5 =0\\\therefore 2x^2 - 2x + 5x - 5 =0\\\therefore 2x(x - 1) + 5(x - 1) =0\\\therefore (x - 1) (2x+ 5) =0\\\therefore x - 1 = 0\: or \: 2x + 5= 0\\\therefore x = 1\: or \:2x = - 5\\\therefore x = 1\: or \:x = - 2.5\\\huge \purple {\boxed {\therefore x = \{-2.5,\: 1\}}}[/tex]

Answer: a) 338 miles

b) $52.26

Step-by-step explanation: To get the amount of miles that your car can drive before running out of gas, you just multiply how many gallons you have by how many miles each gallon lasts. Then, to get the cost of all the gas, you multiply the cost of the gas by how many gallons you need.

C. uses a visual representation of the logical flow of steps needed to reach a conclusion.

Explanation: This is the correct answer on Edge 2021, just took the unit test. Hope this helps ^-^.

A flowchart proof uses a visual representation of the logical flow of steps needed to reach a conclusion. (Option C)

A flowchart proof is a technical proof in which boxes with arrows move from one to the next.

Hence, it is correct to state that a flowchart proof uses a visual representation of the logical flow of steps needed to reach a conclusion.

A: No, the number 200 is not a perfect square.

B: No, the number 200 is not a perfect cube.

C: Yes. the number 200 is neither.

No number times itself twice or threefold is 200 therefore I can conclude it's neither.

Answer: neither because a perfect square is number like 9 or 100 where 3^2=9 and 10^2=100 and likewise for a perfect cube. 200 is not a perfect square or perfect cube for any number

Answer:

-19

Step-by-step explanation:

[tex]f(x) = 5 , f(x) = -3x-4[/tex]

We just have to plug in 5 into f(x) and solve for y

[tex]f(5) = -3(5) - 4 \\f(5) = -15 - 4 \\f(5) = -19[/tex]

Answer:

Since the -5 is a bigger number than 1 you would keep the negative and carry it to the -4.

Answer:

x= -6

Step-by-step explanation:

I think this is right?

Answer: 2

|2x-12|= -4x

2x-12= -4x

-12= -6x

2=x

x=2

Steps to solve:

-7x - 5y = -68 when x = -6

~Substitute and simplify

-7(-6) - 5y = -68

42 - 5y = -68

~Subtract 42 to both sides

-5y = -110

~Divide -5 to both sides

y = 22

Answer:

x= 1/6

Step-by-step explanation:

1) Add the same term to both sides of the equation

2/x+1=3/x-5

2/x+1-1=3/x-5-1

2) Simplify-Add the numbers

2/x=3/x-6

3) Multiply all terms by the same value to eliminate fraction denominators

4) Simplify

5) Add the same term to both sides of the equation

6) Simplify

7) Divide both sides of the equation by the same term

8) Simplify

1/6=x

Answer:

  perpendicular

Step-by-step explanation:

The first equation can be written in slope-intercept form as ...

  y = -1/2x - 3

In this form, we see that the slopes of the two lines are -1/2 and 2, so the product of their slopes is -1. That means the lines are perpendicular.

Answer:

[tex]-\frac{8}{15}[/tex]

Step-by-step explanation:

To divide a fraction by another fraction, you flip the second fraction and also change the divide sign to a multiply sign.

[tex]-\frac{2}{5}\div \frac{3}{4}=-\frac{2}{5}\times \frac{4}{3}[/tex]

Multiply:

[tex]-\frac{2\times \:4}{5\times \:3}[/tex]

[tex]-\frac{8}{15}[/tex]

Answer:

a ratio is a comparison of two numbers or measurements

the objects being compared are called the terms of the ratio.

if the tow terms are different units this is called a rate.

example:

David covers 600 miles in 8 hours and John covers 380 miles in 5 hours. Who is driving faster ?

solution:

Distance covered by David in 1 hour is

=  600 / 8  

=  75 miles per hour

Distance covered by John in 1 hour is

=  380 / 5  

=  76 miles per hour

When we compare the above unit rates (Distance covered in 1 hour), John is driving faster than David.

We can use unit rates to solve pricing problems because we solve for price of one of that item.

For example, David bought 5 pounds of peanuts for $10, how much does it cost for one pound?

10 / 5 = $2 per pound

The $2 is the unit rate and we use to find if David buys more then 10 pounds.

Best of Luck!
