What is the inverse of y=(x-6)^2 +2 ?

Answer:

44L

Step-by-step explanation:

Mary has 20 liters of paint that have white:blue ratio of 2:3. She wants to make a new mix by adding more blue paint until the ratio becomes 1:7. That means the volume of white paint of the old mid and new mix should be the same.

The volume for the second mix will be:

old mix white paint = new mix white paint

2/(3+2) * 20L = 1/(1+7) * V2

2/5 * 20L= 1/8 V2

8L= 1/8 V2

V2= 8L * 8

V2= 64L

If the new mix volume is 64L and old mix volume is 20L, then the blue paint needed to be added will be: 64L- 20L= 44L

Answer:

k = -7/9

Step-by-step explanation:

9k + 3 = -4

9k = -7

k = -7/9

On the number line just make a closed circle at -7/9. No line would be drawn, just the dot

-7/9 would be between 0 and -1, closer to -1

Answer:

k = -7/9

Step-by-step explanation:

If the equation is, 9k + 3 = -4, then;

9k =-4-3,

9k =-7,

k=-7/9

and on a number line just show a point with value -7/9, there is no inequality here

Solution:

Given that,

At 10 a.m., Hillary left City A and drove at an average speed of 120 km/h

Charlene drove at an average speed of 144 km/h and took 50 minutes.

She arrived at City B at the same time as Hillary

Their distance is same

Find the ratio of speed

120 : 144

Reduce to lowest term

Hillary : charlne = 5 : 6

Find the ratio of time:

Since, speed and time are inversely propotional

Hillary : charlne = 6 : 5

Let time taken by Hiliary be 6t

Let time taken by charlene be 5t

Given that, Charlene took 50 minutes

Therefore,

5t = 50

t = 10

Thus,

time taken by Hiliary = 6t = 6(10) = 60

Thus hiliary took 60 minutes to reach

Find the time Charlene left City A

At 10 a.m., Hillary left City A

Difference between both their time = 60 - 50 = 10 minutes

Thus, Hilairy left city A = 10 am + 10 minutes = 10 : 10 a.m

Thus, Hillary left city A at 10: 10 AM

Step-by-step explanation:

do 150ml*15 tubes is 2,250 ml

2,250/1000 is 2.25L (1L =1000ml is multiply by 1000)

There is 2.25 liter of solution in all tubes.

Edwin fills 15 test tubes.

Each test tube contains 150 millilitres of solution We have to find How many liters of solution in all is there in the test tubes

There are 15 tubes contain 150 milometers of solution

150ml × 15 tubes

Therefore we get,

[tex]150ml*15 tubes =2,250 ml[/tex]

we have convert 2250 ml into l

We know that

1L =1000ml

so divide 2250 by 1000 we will get,

[tex]2,250/1000 =2.25L[/tex]

Therefore there is 2.25 liter of solution in all tubes

Answer:

Sydney is 44 years old

Step-by-step explanation:

Step 1:  Make a system of equations

d = s - 15

d + s = 73

Step 2:  Plug in s - 15 for d in the second equation and solve

s - 15 + s = 73

2s - 15 = 73 + 15

2s  / 2= 88 / 2

s = 44

Answer:1460000 + X

Step-by-step explanation:

Answer:

y = 1.46 * 10⁶ x

Step-by-step explanation:

We can write the following equation:

Let x to represent the number of blue whales and,

let y to represent the total krill eaten by x blue whales per year

1'460,000 = 1.46 * 10⁶

y = 1.46 * 10⁶ x

To solve this problem, let's translate the given information into a mathematical equation and then solve for the unknown number.

The problem states that "1 more than 5 times a number is 26." We can represent the unknown number by a variable, let's use "x." The phrase "5 times a number" can be translated to "5x." Hence, "1 more than 5 times a number" becomes "5x + 1."

Now, according to the problem, this expression equals 26. This gives us the following equation:

5x + 1 = 26

To find the value of x, we need to solve this equation for x. Here are the steps to do it:

1. First, we need to isolate the term with x on one side of the equation. We can do this by subtracting 1 from both sides of the equation to get rid of the "+1".

5x + 1 - 1 = 26 - 1

This simplifies to:

5x = 25

2. Next, we need to solve for x by getting rid of the coefficient 5. We do this by dividing both sides of the equation by 5:

5x / 5 = 25 / 5

This simplifies further to:

x = 5

So the number we were looking for is 5.

To summarize, if 1 more than 5 times a number is 26, then the number is 5.

Answer:

[tex]y = - {10}^{x - 3} - 5[/tex]

Step-by-step explanation:

The parent exponential function given to us is

[tex]y = f(x)= {10}^{x} [/tex]

If this function is reflected over the x-axis, shifted right 3 units and down 5 units, then it becomes:

[tex]y = g(x) = - f(x - 3) - 5[/tex]

This implies that:

[tex]y = g(x) = - {10}^{x - 3} - 5[/tex]

where the negative multplier indicates reflection over x-axis, x-3, indicates shift to the right 3 units, and -5 indicates downward shift 5 units

Answer:

3 yards,5.25 yard,6.75 yards

Step-by-step explanation:

Given,

Each skirt required 3/4 yards fabric

Solution,

1 skirt required fabric =3/4 yards

4 skirts required fabric=4×3/4 yards=3 yards

7 skirts required fabric =7×3/4 yards=21/4 yards=5.25 yards

9 skirts required fabric=9×3/4 yards=27/4 yards=6.75 yards

To find out how many yards of fabric will be used, multiply the number of skirts by the amount of fabric needed for each skirt. For 4 skirts, 3 yards of fabric will be used. For 7 skirts, 5.25 yards will be used. For 9 skirts, 6.75 yards will be used.

To find out how many yards of fabric will be used to make a certain number of skirts, we can multiply the number of skirts by the amount of fabric needed for each skirt. In this case, 3/4 yard of fabric is needed for each skirt.

So, to find out how many yards of fabric will be used to make 4 skirts, we can multiply 4 by 3/4:

4 x 3/4 = 12/4 = 3 yards.

To find out how many yards of fabric will be used to make 7 skirts, we can multiply 7 by 3/4:

7 x 3/4 = 21/4 = 5.25 yards.

To find out how many yards of fabric will be used to make 9 skirts, we can multiply 9 by 3/4:

9 x 3/4 = 27/4 = 6.75 yards.

The angles of the triangle are 39°, 51°, and 90°.

Step-by-step explanation:

Step 1:

The sum of all the angles in any triangle is equal to 180°.

We have two of the three angles in terms of x while the third angle is not given directly. Since it is a right-angled triangle, one of the angles equals 90°.

So the angles of the triangle are [tex]3x,[/tex] [tex]4x-1,[/tex] and [tex]90.[/tex]

Step 2:

Now, we substitute all the angles to a sum of 180 to determine the value of x.

[tex]3x + 4x - 1 + 90 = 180.[/tex]

[tex]7x = 91, x = \frac{91}{7} = 13.[/tex]

So x = 13°. The angles are

[tex]3x = 3 (13) = 39, 4x-1 = 4(13) - 1 = 51.[/tex]

The angles of the triangle are 39°, 51°, and 90°.

Step-by-step explanation:

3x + 4x - 1 = 90⁰

7x = 91

x = 13

Angles are = 39 , 51⁰

Answer:

[tex]x=st[/tex]

[tex]y=-5t[/tex]

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

so

The distance is equal to multiply the speed by the time

Let

s ----> the speed in units per second

d ---> the distance in units

t ---> is the time in seconds

BUG A

we have

[tex]d=18\ units[/tex]

[tex]t=3\ sec[/tex]

The speed is equal to

[tex]s=\frac{d}{t}[/tex]

substitute

[tex]s=\frac{18}{3}=6\ units/sec[/tex]

If x is the point reached by A after t seconds

then

Multiply the speed by the time

[tex]x=st[/tex]

[tex]x=6t[/tex]

BUG B

we have

[tex]d=-15\ units[/tex]

[tex]t=3\ sec[/tex]

The speed is equal to

[tex]s=\frac{d}{t}[/tex]

substitute

[tex]s=\frac{15}{3}=5\ units/sec[/tex]

If y is the point reached by B after t seconds

then

Multiply the speed by the time

[tex]y=st[/tex]

[tex]y=-5t[/tex]  ----> is negative because B is moving in the negative direction

Answer:

x = 6t

y = 5t

Step-by-step explanation:

We know the distance formula:

D = RT

Where

D is distance

R is speed

T is time

Bug A went 18 units after 3 seconds, so the speed is:

18 = R(3)

R = 18/3

R = 6 unit/sec

Bug B went 15 units in 3 seconds, so the speed is:

15 = R(3)

R = 15/3

R = 5 units/sec

x is reached by A after 3 seconds, so

x = 6t

y is reached by B after 3 seconds, so

y = 5t
