Simplify The following equations(This is algebra, so PLEASE, only answer if you KNOW FOR SURE, thank you)

3a+7b+2c-a-4b

-8a-b-(-6c)-2a-b-5c

b-4c+3a-c-9b-4a

Answers

Answer 1

Answer: mostly collect like terms
use associative property which is
(a+b)+c=a+(b+c)
also -a+b-c=(-a)+(b)+(-c) so you can move them around
and remember that:
you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2
youcan only add like terms( like terms are terms that are same name like xor y are differnt, and like terms have same power exg x^2 and x^3 andx^1/2 and such

I will oly put the naswers because I don't have much time

first one: 2a+3b+2c

second one: remember that -(-6c)=+6c so the answer is c-10a-2b

third one: -a-8b-5c

From the second and third steps, we know that m∠TUV = m∠1 + m∠2. We also know that m∠XWV = m∠3 + m∠4. Since ∠TUV and ∠XMV both measure 90°, we can set their measures equal to each other:

m∠TUV = m∠XMV

or equivalently:

m∠1 + m∠2 = m∠3 + m∠4

Next, we can use the fact that ∠1 ≅ ∠3 to say that m∠1 = m∠3, while allows us to replace one with the other. Here, we'll replace m∠3 with m∠1:

m∠1 + m∠2 = m∠1 + m∠4

Subtracting m∠1 from either side:

m∠2 = m∠4, which implies that ∠2 ≅ ∠4, as we wanted to show.

The legs of a right triangle measure 6 inches and 12 inches what is the area fo the triangle

Answers

Answer: 36

Step-by-step explanation:

The area of a triangle is (1/2)lw <- that just means that a triangle is half a square. Length * width is the original formula for solving the area of a square.

6 * 12 = 72; 72/2 = 36

36 because the triangle formula is half of base times height. Base times height would be 72 so half of that is 36

On a coordinate plane, a solid straight line has a positive slope and goes through (0, negative 1) and (3, 0). Everything above and to the left of the line is shaded.Which linear inequality is represented by the graph?

y ≤ One-thirdx − 1
y ≥ One-thirdx − 1
y < 3x − 1
y > 3x − 1

Answers

Answer:

Option B.

Step-by-step explanation:

A solid straight line passes through (0, -1) and (3, 0)

Slope of the line = $(y-y')/(x-x')$

= $(0+1)/(3-0)$

= $(1)/(3)$

Equation of the line passing through (0, -1) will be

y - y' = m(x - x')

$y+1=(1)/(3)(x-0)$

$y=(1)/(3)x-1$

Since this line is solid then there will the sign of (≥ or ≤)

If everything above and to the left of the line is shaded then the inequality will be

$y\geq (1)/(3)x-1$

Therefore, the answer will be option B. $y\geq (1)/(3)x-1$

Triangle XYZ is reflected across the line mc013-1.jpg, and X’ = (2, –15). What are the coordinates of X?

Answers

The image is not provided, therefore for your understanding, I will assume that the image has been reflected across y-axis (condition taken from a similar question).
There are certain reflection rules across whatever you want to reflect. In this case, we want to reflect the shape across the y-axis.
When you reflect a point across the y-axis, y coordinate remains the same, but the x-coordinate is transformed into its opposite, means the sign of the x coordinate will be changed from positive to negative or negative to positive.
Thus,
(x , y)→(-x , y)

X’ = (2, –15) is the point given to you, which is the reflected point. To find the pre-image, consider the rule described above.

X’ = (2, –15) → X = (-2 , -15)

In case, the question says it is reflected over x-axis then we would use another rule which says When you reflect a point across the x-axis, the x-coordinate remains the same, but y-coordinate is transformed into its opposite, means the sign of the x coordinate will be changed from positive to negative or negative to positive.
Then,
X’ = (2, –15) → X = (2 , 15)

A juice can is about 2.25 inches in diameter what is the circumference

Answers

about 7.07 inches. to get this do 2.25 x 3.14 (pi) to get about 7.07

Final answer:

The circumference of a juice can with a diameter of 2.25 inches is approximately 7.065 inches.

Explanation:

The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter. In this case, the diameter of the juice can is given as 2.25 inches. Therefore, the circumference can be calculated as C = 3.14 * 2.25 = 7.065 inches. So, the circumference of the juice can is approximately 7.065 inches.
