Hundredth is the second number after the decimal, meaning when rounded there should only be 2 after the decimal. so since the third number is a 7 its higher than 5 meaning the number before it (4) rounds up (to 5) so your rounded number to the hundredth would be

897.35

When x=9, which number is closest to the value of y on the line of best fit in the graph below?

Maurinko [17]

Answer:

Step-by-step explanation:

If you draw a line through each dots, one being from (2,3) to (8,15) and the other being (2,2) to (9,9). And, then if you draw one that is roughly halfway between the two of the first starting points with a slope of 1.5(which is the other 2 lines slopes combined and divided by two to find an average), and then draw out that line to x=9, you will see that it intersects with 13, which is 1 away from 12. Making it the one closest to the line of best fit

The partial factorization of x2 – x – 12 is modeled with algebra tiles.

garik1379 [7]

Answer:

x² – x – 12 = (x – 4)(x + 3)

Step-by-step explanation:

Identify two numbers that add to -1 and multiply to -12, let's call them p and q.

So ax² + bx + c = (x + p)(x + q)

pq = c

p + q = b.

It is easier to find these numbers by finding factors of -12.

This can be done by splitting the number up until all the numbers are prime.

-12 → 6 × -2 or -6 × 2 → -(3 × 2 × 2)

There can only be two numbers so the only options we have are 6 and -2, -6 and 2, 3, and -4, or -3 and 4.

We can eliminate them by adding them up.

6 + -2 = 4 ≠ -1 so that can't be it.

-6 + 2 = -4 ≠ -1 so that can't be it either.

-3 + 4 = 1 ≠ -1

therefore p and q are 3 and -4 because 3 + -4 = -1.

so x² – x – 12 = (x – 4)(x + 3)

p = -4, and q = 3.

(x – 4)(x + 3) = x(x + 3) – 4(x + 3) = x² + 3x – 4x + 12 = x² – x – 12

Angelica is currently 13 years old she is 2 years older than her brother. Write an equation to represent the situation.Solve ur

sdas [7]

Answer:

Therefore,

$x+2=13$ .......Equation

Angelica's Brother's age is 11 years old.

Step-by-step explanation:

Given:

Let the current age of Angelica's Brother be 'x' years old

Angelica's current age is 13 years old,

According to given condition,

Therefore the Equation will be,

$x+2=13$

On solving this equation we get

$x=13-2=11\\\\x=11\ years$

Therefore,

Angelica's Brother's age is 11 years old.

Therefore,

$x+2=13$ .......Equation

Angelica's Brother's age is 11 years old.

Which classification describes AMNO with vertices M(2, -3), N(3, 1), and<br> 0(-3, 1)?

Sonja [21]

Answer:

Option D

Step-by-step explanation:

32). Given vertices of the triangle are M(2, -3), N(3, 1) and O(-3. 1).

Distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by the expression,

Distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between M(2, -3) and N(3, 1) will be,

MN = $\sqrt{(3-2)^2+(1+3)^2}$

= $\sqrt{1+16}$

= $\sqrt{17}$

Distance between M(2, -3) and O(-3, 1),

MO = $\sqrt{(2+3)^2+(-3-1)^2}$

= $\sqrt{25+16}$

= $\sqrt{41}$

Distance between N(3, 1) and O(-3, 1),

NO = $\sqrt{(3+3)^2+(1-1)^2}$

= 6

Condition for right triangle,

c² = a² + b² [Here c is the longest side of the triangle]

By this property,

MO² = MN² + NO²

$(\sqrt{41})^2=(\sqrt{17})^2+6^2$

41 = 17 + 36

41 = 51

False.

Therefore, given triangle is not a right triangle.

Since, length of all sides are not equal, given triangle will be a scalene triangle.

Option D is the correct option.
