Simplify -3x^2 + 7x + 2 + x^3 – x^2 – 9

Answer:

224,999,992.5

Step-by-step explanation:

i used the BEDMAS rule.

first of all i added 5+10 which is in the bracket.

then, i multiplied 5×2 because in bedmas rule .. tho division comes first in BEDMAS. we check what is comes first from multiplication and division.

after that . i multiplied 9999999×6 then, as you know. if a digit is before the bracket is multiplied to the digit inside the bracket. i mutiplied the product of 9999999×6 with 15.

i dunno what you meant by (5+10)%4. so i just assumed that you meant (5+10)÷4. after i got the product of 59,999,994 ×15. i divided it with 4. now as we are done with BEDM. now only addition and subtraction is left. there is no subtraction.. so i added the products and the quotient .

Now... add 5+10+224,999,977.5

you get the ans 224,999,992.5

Do correct me if i am wrong.

Answer:

The value of x is 5 and the value of y is -2

Step-by-step explanation:

If the question is to determine the values of x and y, this can be related to the elimination method for solving simultaneous equations.

From the third linear equation, -13x = -65, the value of x can be determined.

-13x = -65

Divide both sides by -13

Then,

-13x/-13 = -65/-13

x = 5

∴ The value of x is 5.

To determine the value of y, the value of x is substituted into any of the first two equations. Say -10x + 5y = -60

-10x + 5y = -60

Substitute x = 5 into the equation

-10(5) + 5y = -60

-50 + 5y = -60

Add 50 to both sides

-50 +50 + 5y = -60 +50

Then,

5y = -10

Divide both sides by 5

5y/5 = -10/5

y = -2

∴ x = 5, y =-2

Hence, the value of x is 5 and the value of y is -2.

Answer:

We need to consider the division 8/2.

We know that 1/2 is equal to 0.5, then we just could write a problem where we need to multiply 8 by 0.5, this can be something like:

"You found a box with 8 kittens in it, they are a lot of kittens for you to care, so you decide to give the 50% of them to your friend. How many kittens you end up having?"

Well, there are 8 kittens, which represent the 100%.

how many kittens are the 50%?

We have the equations:

8 kittens = 100%

x = 50%

Take the quotient of these two equations:

x/8 kittens = (50%/100%)

x = (50%/100%)*8 kittens

x = 0.5*8 kittens

and 0.5 = 1/2

then:

x = 0.5*8 kittens = (1/2)*8 kittens

x = 8/2 kittens = 4 kittens.

Answer:

You would move each point on y=P(x) up by three. Or add 3 to each y coordinate

Step-by-step explanation:

This is because we're not manipulating the value of x before it gets multiplied by P.

For example:

If x is set to equal 5 and P equal to 2, then the parent function would have a coordinate of (5,10) since 2(5)=10 but the new function would have a coordinate of (5,13) since 2(5)+3= 13 due to order of operations (2×5 =10, then we add 3).

Answer:

Step-by-step explanation:

Step 1:

Plot y=P(x) from x=-a to x=a with x=0 as the middle point of the distance between a and -a.

Step 2:

Add the value of +3 to each point of y=P(x), ie, y=P(x)+3 meaning that the graph y=P(x) will be pulled up three units on the y axis.

Your calculator tells you that √19 ≈ 4.36. The marks divide each integer interval into 3 parts, so the mark just above 4 corresponds to 4 1/3, or about 4.333. Your mark should be slightly to the right of the 4 1/3 mark on the number line.

Answer:

dude they answer choices that you wrote and the answer choices in the picture aren't the same

Step-by-step explanation:

a) We know that triangle ABD is a right triangle, because of the right angle mark show, and the fact that BD- height, thus perpendicular.

We also know that m<A=30 degrees, due to given diagram.

The sum of all angles in a triangle is 180 degrees. Therefore, m<BDA + m<ABD + m<DAB (Usain Bolt!) = 180 degrees.

m<BAD=30 degrees, m<BDA=90 degrees

Substitute these two in the equation above. You will get that m<ABD=60 degrees.

b) Triangle ABD is a special triangle, with angles of 30,60 and 90.

We know that AD=10[tex]\sqrt{3}[/tex] units.

AD is opposite the 60 degree angle, or <ABD. It is a theorem that the angle opposite to the 60 degree angle is the height (BD) divided by [tex]\sqrt{3}[/tex]. Calculate, and what do you get? BD=10 units!

c) Use the fact that triangle ABC is an isosceles triangle.

d) Use the fact that you know the height, base, and triangle area formula: Base x 1/2 x Height.

I will say no more, but I hope you understand the rest based on your logic.

Complete Question

The coach recorded how fast his runners ran 1 mile. Emmett ran a mile in 9.73 minutes, Kate ran a mile in 10.87 minutes, and Rubin ran a mile in 8.46 minutes. How many more minutes did Emmett run than Robin?

a. 1.37 minutes

b. 1.27 minutes

c. 2.27 minutes

d. 1.27 seconds

Answer:

1.27 minutes

Step-by-step explanation:

Emmett ran a mile in 9.73 minutes

Kate ran a mile in 10.87 minutes

Rubin ran a mile in 8.46 minutes.

How many more minutes did Emmett run than Robin?

This is calculated as:

Number of minutes Emmett ran - Number of minutes Rubin ran

= 9.73 minute - 8.46 minutes

= 1.27 minutes

Option b is correct

Answer:

C

Step-by-step explanation:

When an equation has infinitely many solutions, what we have on the right is also what we have on the left side of the equation

Let’s take a look at the third equation;

5.1 + 2y + 1.2 = -2 + 2y + 8.3

5.1 + 1.2 + 2y = 2y + 8.3-2

6.3 + 2y = 2y + 6.3

This equation has infinitely many solutions
