If 4y = 7x, write the ratio of x to y.

Answer:

$9.55

Step-by-step explanation:

4/100=0.04

0.04x9.95=0.40

9.95-0.40=9.55

4% of 9.95 is 0.398, so you would add about $0.40 to the original amout.

Answer:

We have the relation:

aₙ = 10 + 2*(n - 1)

And we want to write this in fuction form:

y = f(n)

first we have:

aₙ = y =  10 + 2*(n - 1)

We can rewrite this as:

y = 10 + 2*n - 2

y = 2*n + (10 - 2)

y = 2*n + 8

Now we want to find the y-intercept, this is the value of the function when the variable is equal to zero.

Then if we take n = 0, we get:

y = 2*0 + 8

y = 8

The y-intercept is 8.

Answer:

19y - 34x = 376

Step-by-step explanation:

We are to write the linear equation of a line passing through the points

(-20, -16), (-1, 18)

Using the points slope form of the equation expressed as;

y-y0 = m(x-x0)

m is the slope

(x0,y0) is any point on the line

m = y2-y1/x2-x1

m = 18-(-16)/-1-(-20)

m = 18+16/-1+20

m = 34/19

Substitute the slope m =34/19 and the point (-1, 18) into the expression given

y- 18 =34/19(x-(-1))

19(y-18) = 34(x+1)

19y - 342 = 34x+34

19y-34x = 34+342

19y - 34x = 376

Hence the required equation is 19y - 34x = 376

Step-by-step explanation:

Answer:

40 minutes

Step-by-step explanation:

47-7 is 40

Answer:

First, let's find the equations for our lines:

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

f(x) passes through (5,0) and (10, 10), then the slope is:

a = (10 - 0)/(10 - 5) = 10/5 = 2.

then we have:

y = 2*x + b

And when x = 5, we have y = 0.

0 = 2*5 + b

0 = 10 + b

b = -10

Then the equation for f(x) is:

y = f(x) = 2*x - 10.

Now for g(x) we have the points:

(3, 0) and (2, 10)

a = (10 - 0)/(2 - 3) = -10

y = -10*x + b

0 = -10*3 + b

b = 30.

y = g(x) = -10*x + 30.

A) Ok, the transformations:

Transformation 1 or T1.

f(x) = 2*x - 10

g(x) = -10*x + 30.

Then, we start with f(x):

First, we can move f(x) up 4 units and get:

f'(x) = 2*X - 6

Now we can dilate f(x) with a scale factor of -5 from the origin, now we get:

f''(x) = -5*f'(x) = -10*x + 30.

And this is g(x).

Transformation 2 or T2.

Move f(x) up 10 units, so now we have:

f'(x) = 2*x

Do a reflection over the x-axis, so the sign of y changes, and now we get:

f''(x) = -2*x

Do a dilation of scale factor 5

f'''(x) = 5*-2*x = -10*x

Now do a vertical translation of 30 units up.

f''''(x) = -10*x + 30 = g(x).

These are two transformations that start with f(x) and end with g(x).

B) Ok, as i was writting the transformations i already solved them, so this part is already done.

C) the equation for the transformations are:

T1) g(x) = -5*(f(x) + 4)

T2) g(x) =  -(f(x) + 10)*5 + 30

Answer:

0u

7u

6u

2u

Step-by-step explanation:

All of these question are just a matter of adding like terms

For the first one we have

7u+(-u)+(-6u)

which is equal to

7u-u-6u

Which I'm sure you can see is equal to 0 or 0u

10/2u+2u

10/2u=5u

5u+2u=7u

6u+0u

0u=0

6u

6u+(-4u)

6u-4u

2u

Answer:

966 joules

Step-by-step explanation:

Step one:

given data

mass of car= 950kg

angle of incline= 15°

Applied force= 200N

displacement = 5m

If we apply a force on an object through a distance work is done, hence Mechanical work is the product of a force applied on an object and its displacement while that force is applied

Step two:

Work done= Force * distance

Since the car is moved on an inclined plane, the expression for the work done is

Work-done= Frcos∅

where r is the distance moved

Work-done= 200*5cos 15

Work-done= 200*4.83

Work-done= 966 joules

Answer:15

Step-by-step explanation:

distance = Sqrt((x2-x1)^2 +(y2-y1)^2)

15-3 =12

16-7=9

12^2 = 144

9^2 = 81

144+81 = 225

square root of 225 = 15

the distance is 15

Answer:

M = 36

Step-by-step explanation:

Since SAM = ZYX

We can assume that all angles on SAM will equal the same as ZYX.

There are 180° total in a triangle, so you add 60 + 84, which equals 144, then you subtract 144 from 180 to find the remaining angle.

Therefore M = 36°

Answer: 7.29 or 7 1/4 or 29/4 (they're all equal, just rewritten)

Step-by-step explanation:

the angles are equal, so we set the equations to each other and then solve. here's my work:

12k - 9 = 8k + 20

12k (- 8k) - 9 = 8k ( - 8k) + 20

4k - 9 = 20

4k -9 ( + 9) = 20 ( + 9)

4k = 29

k = 7.29 or 7 1/4 or 29/4

x=12

Hope this helps

Answer:

The answer is x = 12

Step-by-step explanation:

So, first you're going to add 8 on both sides

6x - 8 +8 = 5x + 4 + 8

Then simplify

6x = 5x + 12

Then subtract 5x from both sides

6x - 5x = 5x + 12 - 5x

Then simplify again and you get

x = 12

like saying 3+4+5=5+4+3

Answer:

Part 1: $344.25 -$6.75(d) = A

This equation I have made makes since because 344.25 represents the money I have now. If I were to spend 6.75 * d days, that would give me the total money left in my account after how many number days.

Part 2: $344.25/$6.75 = 51

It would take 51 days for me to have $0.00 in my account. I know this because I divided the total money I have in my account by how much I spend on lunch everyday. Knowing this, I know how many days it'd take for me to have $0.00

Answer:

The corresponding side length is 8 inches

Step-by-step explanation:

Similar Shapes

Two shapes are similar if all of their side lengths are in the same proportion. For example, triangle 1 has sides of 3-4-5 and another similar triangle has sides of 15-20-25. Note all their lengths are proportional with a scale factor of 5.

We are given the perimeter of figure A Pa=24 inches and the perimeter of figure B Pb=36 inches. The scale factor can be obtained as 36/24=3/2.

If one of the lengths of figure B is 12 inches, then the corresponding length for figure A is 12/(3/2) = 8 in.

The corresponding side length is 8 inches

Answer:

Slope is 1

Step-by-step explanation:

(-4,-1) (-3,1)

m =  y2 - y1 / x2 - x1

Answer:

2

Step-by-step explanation:

Slope is defined as change in y over change in x

if we count, we can tell that the change in y is up 2 boxes for every 1 box you take to the right. We count 1 box right every time so we are always going in the positive direction.

Since slope is change in y over change in x, then you get 2/1 = 2.
