y= -4x + 7
y= 1/4x -2

a. the same line
b. distinct parallel lines
c. perpendicular lines
d. intersecting, but not perpendicular lines

Answer:

x = 20

Step-by-step explanation:

[tex](2x) \degree + x \degree+ 60 \degree + (360 - 120) \degree = 360 \degree \\ \\ (3x) \degree+ 60 \degree + 240 \degree = 360 \degree \\ \\ (3x) \degree+ 300 \degree = 360 \degree \\ \\ 3x = 360 \degree - 300 \degree\\ \\ (3x ) \degree= 60 \degree \\ \\ 3x = 60 \\ \\ x = \frac{60}{3} \\ \\ x = 20 [/tex]

Answer:

parallel------> y = - 4x + 24

perp.---------> y = 1/4x - 3/2

Step-by-step explanation:

parallel: 4 = - 4(5)+ b

4 = -20 + b

+20 = +20 + b

24 = b

y = -4x + 24

perpendicular: 4 = 1/4(5) + b

4 = 5/4 + b

- 5/4 = - 5/4 + b

- 3/2 = b

y = 1/4x - 3/2

Answer:

Rosa is correct in using a division expression because the term "per" implies the quotient of the quantities before and after that word.

Step-by-step explanation:

Given that

1 pound of ground beef sells for $4.

To find the cost per pound:

We need to divide the cost with the number of pounds.

i.e.

[tex]\text{Cost per pound = }\dfrac{\text{Total Cost}}{\text{Number of pounds}}[/tex]

If 'Number of pounds' = 1, then cost per pound = Total Cost

Therefore, the above division expression can be used to find the Cost pound.

Putting the values given to find the 'Cost per pound':

[tex]\text{Cost per pound = }\dfrac{\$4}{1} = \$4[/tex]

Therefore, Rosa's belief is correct that, a division expression can be used.

The correct answer is:

Rosa is correct in using a division expression because the term "per" implies the quotient of the quantities before and after that word.

Answer:

The second number is four more than, two times the first number. The third ... Start by writing an expression for each of the three numbers. They are all formed from the first number, so let's call the first number x . Let the first number be x. The second number is 2x+4. The third number is 3x−5. We are told .

Answer:

We have to estimate the sum of

→7.95 + 8.11 + 78.5 + 8.05 + 79.4 + 0.815

When Rounded to nearest tens

7.95 → 8.00

8.11→ 8.00

78.5→79

8.05→8.00

79.4→79.0

0.815→1

Step-by-step explanation:

So,estimation of the above rational numbers with addition as an operation is done,the result is

→8 + 8 + 80 + 8 + 80 + 0.8 = 184.8, is not correct ,because in the expression it is not clear , the numbers are neither exactly rounded to nearest tens or tenths.

Answer:

150 mph

Step-by-step explanation:

Two point five miles times 60 minutes.

Answer:

241,395 mph

Step-by-step explanation:

There are about 1609.3 meters in one mile, so to convert miles to meters just multiply the number of meters by the miles you have. This will cancel out the unit of miles and leave you with meters per min.

[tex]\frac{2.5mi}{min} *\frac{1609.3m}{1mi}=\frac{4023.25mmi}{mimin}=\frac{4023.25m}{min}[/tex]

Then multiply that by 60 because there are 60 minutes in an hour

[tex]\frac{4023.25m}{min}*\frac{60min}{1h}=\frac{241,395mmin}{minh}=\frac{241,395m}{h}[/tex]

2.5 mi/min = 241,395 mph

Answer:

28

Step-by-step explanation:

Answer:

x = 12

Step-by-step explanation:

4 (x + 1) + 8 = 24

you wan to simplify

4x + 4 + 8 = 24

4x + 12 = 24

now you want to get the variable and the number on different sides

4x + 12 - 12 = 4x

24 + 12 = 36

4x = 36

now you wan to divide each side by 4

4x / 4 = x

36 / 4 = 12

x = 12

Answer:

The answer is 3.

Step-by-step explanation:

First, subtract 8 from each side of the equation to isolate the term with parenthesis while keeping the equation balanced

Next, divide each side of the equation by 4 to eliminate the parenthesis while keeping the equation balanced

Now, subtract 1 from each side of the equation to solve for x while keeping the equation balanced.

Answer:

[tex]\boxed{\tt a=9}[/tex]

Step-by-step explanation:

We are given the equation:

[tex]-5a+7= -38[/tex]

We want to solve for a, so we must isolate a on one side of the equation.

7 is being added to -5a. The inverse of addition is subtraction. Subtract 7 from both sides of the equation.

[tex]-5a+7-7=-38-7[/tex]

[tex]-5a=-38-7[/tex]

[tex]-5a=-45[/tex]

a is being multiplied by -5. The inverse of multiplication is division. Divide both sides of the equation by -5.

[tex]\frac{-5a}{-5} =\frac{-45}{-5}[/tex]

[tex]a=\frac{-45}{-5}[/tex]

[tex]a=9[/tex]

Let's check our solution. Plug 9 in for a.

[tex]-5a+7=-38[/tex]

[tex]-5(9)+7=-38[/tex]

[tex]-45+7=-38[/tex]

[tex]-38=-38[/tex]

This checks out, so we know our solution a=9 is correct.

-5a +7 =-38

-5a +7 (-7) = -38 (-7)

-5a= -45

-5a (÷-5)= -45 (÷-5)

a= 9

Answer:

Step-by-step explanation:

Given parameters:

Force  = 30N

Distance covered  = 3m

Unknown:

Work done = ?

Work done is an important physical quantity. It is formulated as the product of force and distance.

   Work done  = Force x Distance

The unit is in Joules.

Now go ahead and input the parameters;

                  Work done  = 30 x 3  = 90J

The work done in pushing the car is 90J

Answer:

144.8 would be your answer, if I'm not mistaken.

Step-by-step explanation:

To find the MAD (Mean Absolute Deviation) you have to add up all the numbers and divide it by the amount of numbers you are being given:

[tex]36+42+41+32+30=181[/tex]

Then divide it by 5 because we added 5 numbers together:

[tex]\frac{181}{5} =36.2[/tex]

People actually do it like this:

[tex]\frac{36+42+41+32+30}{5} = 181[/tex]

(Which is the same thing, except it's faster, in my opinion)

Well, now that we have the sum (181) we have to subtract it from all those numbers we were given:

[tex]181-36=145, 181-42=139, 181-41=140, 181-32=149, 181-30=151.[/tex]

Now add up all those numbers together and divide it by 5 again:

[tex]\frac{145+139+140+149+151}{5} =144.8[/tex]
