Answer:

25% increase

Step-by-step explanation:

Answer:

Step-by-step explanation:

Since this is not factorable, let's just complete the square:

[tex]x^2+6x=19\\x^2+6x+9=28\\(x+3)^2=28\\x+3=\sqrt{28}\\x=2\sqrt{7}-3[/tex]

Answer:

The solution to the system of equations will be:

[tex]x=9,\:y=6[/tex]

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}2x-9y=-36\\ -14x+18y=-18\end{bmatrix}[/tex]

Multiply 2x-9y=-36 by 7

[tex]14x-63y=-252[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}14x-63y=-252\\ -14x+18y=-18\end{bmatrix}[/tex]

Adding both equations

[tex]-14x+18y=-18[/tex]

[tex]+[/tex]

[tex]\underline{14x-63y=-252}[/tex]

[tex]-45y=-270[/tex]

solve -45y = -270 for y

[tex]-45y=-270[/tex]

divide both sides by -45

[tex]\frac{-45y}{-45}=\frac{-270}{-45}[/tex]

Simplify

[tex]y=6[/tex]

For 14x-63y = -270 plug in y = 6

[tex]14x-63\cdot \:6=-252[/tex]

[tex]14x-378=-252[/tex]

Add 378 to both sides

[tex]14x-378+378=-252+378[/tex]

Simplify

[tex]14x=126[/tex]

Divide both sides by 14

[tex]\frac{14x}{14}=\frac{126}{14}[/tex]

Simplify

[tex]x=9[/tex]

Therefore, the solution to the system of equations will be:

[tex]x=9,\:y=6[/tex]

Answer:

the amount is duplicating every time from 1 to 2 from 8 to 16

Step-by-step explanation:

Answer:

it's being multiplied by 2 every time, so 1×2=2 and it just keeps going on. 2×2=4, 4×2=8 and so fourth

Answer:

3x

Step-by-step explanation:

The GCF would be 3x, if you took out 3x from those numbers you'd be left with x^2, 2x, and 5, which can't be reduced any further.

Answer:

yes, the triangle is congruent because they all have the same three sides on each.

The value of the function at x = 2 is -100

They are written in the form y = ab^x

Given the exponential function y = -4(5)^x

IF the value of x is 2, hence the expression becomes:

y = -4(5)^2

y = -4(25)

y = -100

Hence the value of the function at x = 2 is -100

Less = 0.24

More = 0.76

Step-by-step explanation:

Given that:

Numbers drawn by Carmen :

4, 7, 6, 0, and 2

To make a decimal less than 1 from the numbers drawn:

First digit would be always be 0 since we aren't considering negative numbers

If they are playing for less; then the least 2 digits will be used in ascending order after the decimal point as;

2, 4

0.24

If they are playing for more; then the highest 2 digits will be used in descending order after the decimal point as;

7, 6

Answer:

w=V/Ih

Step-by-step explanation:

The formula for the volume of a rectangular prism is given as V = lwh.

✓ we are required to solve for "w" and this can be done by making "w" subject of the formula.

w=V/Ih

Hence, formula for " w" is w=V/Ih

Answer:

x=12

Step-by-step explanation:

Subtract 2 from both sides

Subtract 2 from 12 to get 10

Divide both side by 5

Finally,divide 10 by 5 to get 2

5(2)+2=12

Infinite Many Solutions

Step-by-step explanation:

If I am correct the two lines are overlapping each other in more than one place so that means there are infinitely many solutions. Also, there can be no " two solutions" for this type of equation. There can only be one solution, no solution, or infinitely many solutions.

Answer:

56

Step-by-step explanation:

The angle sum theorem *I think* is that for an n-sided shape, the total sum of its angles is 180(n-2).

The sum of a triangles' angles is 180 degrees.

Therefore 4v-44 = 180.

v - 11 = 45

v = 56 degrees

Note: always check if the answer makes sense

Answer:

56 degrees

On the graph, it tells you how much fuel is left after 2 hours of the journey.

If we take 422,000 and subtract 369,250 from it we get 52,750. However, this is how much gas is used in 2 hours, so to find one hour we need to divide by 2, getting us 26,375.

Therefore, the Jet uses 26,375 gallons per hour during the 16 hour trip from Los Angeles, CA to Melbourne, Australia.

Answer:

3/2

Step-by-step explanation:

As, 9 is a factor of three so, 9÷3 = 3

So now it's like this: 7/1 x 3/14

Now here 14 is also a factor of 7 so 7 x 2 = 14

So we will cancel it

So, now it's like this 1/1 x 3/2

So finally each an every number that is multipled by 1 is the same so the finally product = 3/2

Or u can just multiply and then divide

7/3 x 9/14 = 63/42

Now u can check both are divisible by 7

So now we will divide by seven so now its

9/6

Here also they are divisible by 3

Divide both numerator and denominator

And u will get 9÷ 3 = 3

And 6÷3 = 2

So, = 3/2

Chose the easier for u!
