Answer 1

Answer:

3 + 2n

Step-by-step explanation:

2 + 1 = 3.

2n cannot be added into this because it has a letter in front of it. Therefore, it stays on its own.

Answer 2

2n + 3

1 and 3 are like terms, and because there are no more variables, the 2n will stay alone :)

x^2-10x=12​

Answers

Answer:

Step-by-step explanation:

x²-10x = 12

Coefficient of the x term: -10

Divide in half: -5

Square it: (-5)² = 5²

Add 5² to both sides:

x²-10x+5² = 12+5²

(x-5)² = 37

Answer:

-9C

Step-by-step explanation:

-3+5-2-3(3)=-9C

i think you made a mistake on "it got colder by 2C." If temperatures get colder, they drop, meaning you subtract it.

also, it said between the hours of 6-10pm, which is three hours, the temperature drops each hour by 3C. so, you multiply 3 to -3, and come up with -9

Answer:

B is (3, 10)

Step-by-step explanation:

The midpoint of coordinates of the 2 points (x1, y1( and (x2, y2) is

(x1 + x^2) / 2 , (y1 + y2)/2.

So if (x, y) are the coordinates of B we have:

(7 + x)/2 + (2 + y)/2 = 5 + 6

So 7 + x = 2*5 so x = 3

AND 2 + Y = 12 SO y = 10.

The segment AB has the endpoints A(1,5) and B(3,2). The segment is translated 2 units down and 2 units right. What are the endpoints of the translated segment A'B'?

Answers

The endpoints of the translated segment A'B' after undergoing the given translation is; A'(3, 3) and B'(5, 0)

How to carry out translation transformation?

In transformation in mathematics, there are different types such as dilation, reflection, rotation, translation e.t.c

Now, in this case what we are dealing with is translation which simply means moving an object or figure from one point to the other without changing the shape or dimensions.

To translate the point AB(x, y) , 2 units down and 2 units right, we will use the translation rule;

A'B'(x + 2, y − 2) .

We are given the coordinates of AB as A(1,5) and B(3,2)

Thus;

A'(1 + 2, 5 - 2) = A'(3, 3)

B'(3 + 2, 2 - 2) = B'(5, 0)

Answer:

f(-2) = 2f(0) = 4

Step-by-step explanation:

a) Locate the point -2 on the x-axis. Follow the line up until it meets the blue curve. Follow that grid line to the right to see where it meets the y-axis. It is y=2. That means f(-2) = 2.

__

b) Locate y=4 on the y-axis. Notice that the curve intersects the y-axis there, so x=0.

x = 0 is the only value of x for which f(x) = 4.

Solve for all values of x by factoring.
x2+ 13x + 43 = 1

Answers

Answer:

Move 1 to the left side of the equation by subtracting it from both sides. Subtract 1 from 43.

Uri has 22 same-sized circles that are divided into different numbers of equal-sized parts. He shades 1/5 of the first circle. The second circle has three times as many parts as the first circle. Uri shades an equivalent fraction of the second circle. What fraction of the second circle does Uri shade?

Answers

Answer:

The fraction of the second circle does Uri shade = [tex]\frac{1}{15}[/tex]

Step-by-step explanation:

As given,

Total number of same sized circle = 22

In first circle :

He shades [tex]\frac{1}{5}[/tex] of the first circle.

⇒ He divide the first circle in 5 parts and shaded 1 part.

Now,

The second circle has three times as many parts as the first circle.

⇒Total parts of second circle = 3 × 5 = 15

Now,

Given that  Uri shades an equivalent fraction of the second circle.

⇒Uri shade second circle = [tex]\frac{1}{15}[/tex]

∴ we get

The fraction of the second circle does Uri shade = [tex]\frac{1}{15}[/tex]
