Answer:

The red present. 760%

Answer:

760%

Step-by-step explanation:

38 is 760% of 5. This can be determined by dividing 38 by 5 and then multiplying it by 100.

38/5 = 7.6

7.6 x 100 = 760%

Answer:

9. a = -7

10. x = 1

Equality Properties

Step-by-step explanation:

Step 1: Define equation

a + 6a - 14 = 3a + 6a

Step 2: Solve for a

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Here we see that -63 is equal to -63.

∴ a = -7 is a solution of the equation.

Step 4: Define equation

-12 - 4x = 8x + 4(1 - 7x)

Step 5: Solve for x

Step 6: Check

Plug in x into the original equation to verify it's a solution.

Here we see that -16 does indeed equal -16.

∴ x = 1 is a solution of the equation.

Answer:

Open circle. Points right

Step-by-step explanation:

The reason for it is because this symbol > represents greater than when it comes to inequalities. When it is an open circle that means that you are not including the number. So that also means that the -2.5 is not included to the inequality equation but it can be any other number other than that number.

Answer:

z = 3

Step-by-step explanation:

z - (-12) = 15

z + 12 = 15

z = 15 - 12

z = 3

Thus, The value of z is 3

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

Polynomial Roots Calculator :

3.3 Find roots (zeroes) of : F(x) = 3x3+4x2+9x+28

Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 3 and the Trailing Constant is 28.

The factor(s) are:

of the Leading Coefficient : 1,3

of the Trailing Constant : 1 ,2 ,4 ,7 ,14 ,28

Let us test ....

Polynomial Roots Calculator found no rational roots

Greetings again.

The answer is (-3,6)

Explanation:

As explained in the your previous question about eliminating the term.

We can either eliminate x-term or y-term to find/solve another term first. But It's easier to eliminate the term without multiplying to make both terms the same.

By adding/subtracting vertically for two equations. We get that the adding y and -y makes them 0.

Therefore, we eliminate y-term to solve x first.

[tex]\left \{ {{2x+y=0} \atop {3x-y=-15}} \right. \\5x=-15\\[/tex]

I explained about adding/subtracting vertically.

Basically, 2x+3x = 5x

y - y = 0

0 - 15 = -15

That's how to get 5x = -15

[tex]x=-3[/tex]

Because it is the system of two linear equations. We need to find the y-term too.

Therefore, substitute x = -3 in any given equations. I suggest you to substitute x = -3 in the equation with less coefficient value.

So I'll substitute x = -3 in 2x+y = 0 instead because the first equation has less coefficient than the second equation.

[tex]2x+y=0[/tex]

Substitute x = -3 in the equation.

[tex]2(-3)+y=0\\-6+y=0\\y=6[/tex]

Therefore, when x = -3, y = 6. Since you want the answer as an ordered pair. The answer is (-3,6)

Answer: 2pts = 5 & 3pts = 20

Step-by-step explanation:

Let the number of 2 pointers be x

Lwt the number of three pointers be y.

Based on the information in the question, we can represent this as an equation. This will be:

a + b = 25 ...... i

2a + 3b = 70 ...... ii

Multiply equation i by 2

Multiply equation ii by 1

2a + 2b = 50 ...... iii

2a + 3b = 70 ...... iv

Subtract equation iii from iv

b = 20

Recall that a + b = 25

a + 20 = 25

a = 25 - 20 = 5

Therefore, 2pts = 5 and 3pts = 20

Try putting it in your calculator. What digit comes next? Any number you pick from 0 to 9 is a guess. That's one of the ways you can tell if a number is irrational or not. You could get the answer from the calculator that came with windows. It gives the answer to 18 digits, but you'd still be guessing the 19th one.

The others are all well behaved in comparison.

Answer:

Let's factor x2+3x−18

x2+3x−18

The middle number is 3 and the last number is -18.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 3

Multiply together to get -18

Can you think of the two numbers?

Try -3 and 6:

-3+6 = 3

-3*6 = -18

Fill in the blanks in

(x+_)(x+_)

with -3 and 6 to get...

(x-3)(x+6)

Answer:

(x−3)(x+6)

Step-by-step explanation:

Answer:

50 ft

cuz

a squared plus b squared is c squared

then we can substitute a for 40

and we can also substitute to b for 30

then we Square them

1600+900 = 2500

lastly we root square 2500

in order to get the hypotenuse 50 feet

Hi there.

The answer is (x-2y-8)(x-2y-4)

There is a positive correlation between the variables. The variables relate to each other because as x (the temperature) increases, the sales of ice cream (in dollars) increases as well.

Answer:

They all are sorta aligned and close together

Step-by-step explanation:

In my perspective when variables are aligned they are equal and are easier to work with.
