Answer:

first off theres two ways of doing it the equation is more fun though

14.5 = x + 4.5

14.5 = x(5) -4.5

-4.5

10 = 5x

divide by 5

you get

2x or $2

other way was to just -4.5 and divide by 5 but thats no fun

Answer:

[tex] \because \:l_{1} \parallel \: l_{2} \\ \therefore m_{1} = m_{2} = \frac{1}{2} \\ \frac{y - 6}{x + 3} = \frac{1}{2} \\ y - 6 = \frac{1}{2}x + \frac{3}{2} \\ y = \frac{1}{2}x + \frac{3}{2} + 6\\ y = \frac{1}{2}x + \frac{15}{2}[/tex]

Answer:

[tex]y=\displaystyle\frac{1}{2}x+\displaystyle\frac{15}{2}[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]y=\displaystyle\frac{1}{2} x+5[/tex]

From the given equation, we can tell that the slope is [tex]\displaystyle\frac{1}{2}[/tex]. Because parallel lines always have the same slope, the slope of the line we're solving for is therefore [tex]\displaystyle\frac{1}{2}[/tex] as well. Plug this into [tex]y=mx+b[/tex]:

[tex]y=\displaystyle\frac{1}{2}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=\displaystyle\frac{1}{2}x+b[/tex]

We're given that the line passes through the point (-3,6). Plug this into [tex]y=\displaystyle\frac{1}{2}x+b[/tex] and solve for b:

[tex]6=\displaystyle\frac{1}{2}(-3)+b\\\\6=\displaystyle\frac{-3}{2}+b\\\\b=\frac{15}{2}[/tex]

Therefore, the y-intercept is [tex]\displaystyle\frac{15}{2}[/tex]. Plug this back into [tex]y=\displaystyle\frac{1}{2}x+b[/tex]:

[tex]y=\displaystyle\frac{1}{2}x+\displaystyle\frac{15}{2}[/tex]

I hope this helps!

Answer: The other factor is 70

Explanation: 4,200 divided by 60 is 70.

Answer:

89240

Step-by-step explanation:

_ 9 _ _ _ is in the thousands

_ 9 _ _ 0 is in the ones

going to assume you meant 8 is in ten thousands

8 9 _ _ 0 is in ten thousands

8 9 _ 4 0 is in tens

8 9 2 4 0 is in hundreds

School number is 89240

Answer: 98,240

What we are doing here is changing from expanded form into standard form.

To do that, you add all the place values to get the total number. So, our place values are:

10,000 - Ten Thousands Place

1,000 - Thousands Place

100 - Hundreds Place

10 - Tens Place

Now, we will need to look at the problem.

It says, The 9 is in the ten thousand place, the 0 is in the ones place, an 8 is in the thousands place, a 4 is in the tens place and a 2 is in the hundreds place.

According to the question, the 9 will be in the Tens Thousands Place, so our first number will be, 90,000.

The 8 will be in the Thousands place, so our second number will be 8,000.

The 2 will be in the Hundreds place, so our third number will be 200.

The 4 will be in the Tens place, so our fourth number will be 40.

Since the one's place is 0, we don't need to worry about that number.

Putting the answer in an equation, it will be like this,

Now we can add.

Adding these numbers up will equal to, 98,240.

Therefore, the answer is 98,240.

Answer:

l = 7x - 9

Step-by-step explanation:

The length of the rectangle is represented by the expression "7x - 9".

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

The perimeter of a rectangle is given by the formula:

Perimeter = 2 (length + width)

Therefore, we can set up the equation:

20x - 18 = 2 (length + (3x - 1))

Expanding the parentheses and combining like terms, we get:

20x - 18 = 2 × length + 6x - 2

Moving all the terms to one side, we get:

14x - 18 = 2 × length

Dividing both sides by 2, we get:

7x - 9 = length

Thus, the rectangle's length is expressed by the expression "7x - 9".

#SPJ2

Step-by-step explanation:

yes, if your teacher meant to include the default factors of every positive integer number : 1 and the number itself.

these are the 2 positive integer factors.

if a positive number can only be divided without remainder by 1 or by itself (with result 1), then it is per definition a prime number.

if the number can be divided without remainder by another number, then we are not dealing with a prime number.

but if your teacher did not have these default factors in mind, then no :

example : 15

15 has only 2 factors : 3 and 5.

both are positive integer numbers.

and yet 15 is not a prime number.

but back to my first point, 15 also has formally the factors 1 and 15. so, if we count them too, then we have suddenly 4 factors. and the original statement fits again.

Answer:

5

Step-by-step explanation:

Normally the two diagonals of a kite meet at a right angle. That information should not be withheld from you. Otherwise, you are just guessing.

You must assume then that <STP also = 90o

14x + 20 = 90            Subtract 20 from both sides

14x = 90 - 20             Combine

14x = 70                     Divide both sides by 14

14x/14 = 70/14

x = 5

(2x+4y=16).....1

(2x-4y=0).....2

then take equation 1 plus 2

4x=16

x=4

then take equation 2 to solve for y

2x-4y=0

(2×4)-4y=0

y=2

therefore answer is D. (4,2)

The first subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is 1 - ¹/₄

The first subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is

1 - ¹/₄ = ¹/₁ - ¹/₄

taking the L.C.M which is 4, we have

= (4 - 1)/4

= 3/4

So, the first subtraction problem is 1 - ¹/₄

2.

The second subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is 2¹/₂ - 1³/₄

The second subtraction problem that will use only odd numbers as numerators and have a difference of 3/4 is

2¹/₂ - 1³/₄ = ⁵/₂ - ⁷/₄

taking the L.C.M which is 4, we have

= (10 - 7)/4

= 3/4

So, the second subtraction problem is 2¹/₂ - 1³/₄

Answer:

4.5

Step-by-step explanation:

We are here given that ,

=> f(x) = 2x - 5

=> y = 2x - 5

Replace x and y with each other .

=> x = 2y - 5

solve for y ,

=> 2y = x +5

=> y = (x+5)/2

=> f-¹(x) = (x+5)/2

Now ,

=> f-¹(4) = 4+5/2 = 9/2 = 4.5

Answer:

y=(7/4)x + 12, y=(-4/7)x -46/7

Step-by-step explanation:

first for the perpendicular line: we know the slope is the opposite reciprocal of -4/7, so m= 7/4. now we have y= 7/4 x +b. b is the y-intercept. to find b plug in the point (-8,-2). -2=(7/4)(-8) + b = -14+b so b=12. so the slope of the perpendicular line is y=(7/4)x + 12

parallel:

since the line is parallel the slope is -4/7. so we have y=(-4/7)x + b. next plug in the point (-8, -2) to find b: -2 = (-4/7)(-8) + b = 32/7 + b. so b= -46/7

Divide 41 by 140 to get 0.29285714285, and round it to the nearest hundredths.

Answer:

Step-by-step explanation:

b= buttons

z= zips

b∩z'=41

b'∩z=48

b'∩z'=25

b=?

b= b∩z+b∩z' (law of total probability)

140=b∩z+b∩z'+b'∩z+b'∩z'  (if this is confusing draw a venn diagram)

140=b∩z+41+48+25

b∩z=26

26+41= 67
