can someone help me answer this please

Answer:

This is the expression expanded

Step-by-step explanation:

Answer:

a.The associative property allows us to change the grouping of terms that are added together.

b.When changing the grouping, the order of the terms stays the same; only the parentheses change position.

c.The expression a + (b + c) + d is an equivalent expression.

e.The expression (a+ b) + c + d is an equivalent expression.

Step-by-step explanation:

The correct statements are statement first, statement second, statement third, and statement fifth are correct.

It is defined as the combination of constants and variables with mathematical operators.

As we know,

The associative property allows us to change the grouping of terms that are added together.

= a + (b + c)

= (a + b) + c

The correct statements are:

Thus, the correct statements are statements first, second, third, and fifth are correct.

1) C  2) (-2,0) 3) 4)  5) c )S={(0,3)} 6) (0,2) 7)  8) Missing graph 9) Vertical line (check below) 10) B 11)

Step-by-step explanation:

1) Solving by the Addition/Elimination Method. Firstly, let's reduce one variable by making some algebraic adjustments and then adding it up:

2) Solving by Substitution Method. Where y=x+2 is plugged in the 2nd equation.

3) Solving it, again, by the Substitution Method due to the I equation form:

4) By the Addition Method

5) To use the graph method to solve the system of Linear equations is possible by graphing each equation on the Cartesian Plane.

Check the graph below, this system has only one solution.

c)S={(0,3)}

6) Solving y=-1/3x+2 y=x+2

Answer:

b= 3

d= 10/7

Step-by-step explanation:

Basically what you do is 12/6 and 10/7 for d, because it is the greatest and least on both sides. You do the same for b so it would be 10-7=3 and 12-6=6

Answer:

Baking c cookies and dividing them evenly among 4 friends.

Step-by-step explanation:

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (- 1, 6)

m = [tex]\frac{6-4}{-1-1}[/tex] = [tex]\frac{2}{-2}[/tex] = - 1

Answer:

[tex]\boxed{\tt A. \angle8 \ and \angle 7}[/tex]

Step-by-step explanation:

Supplementary angles are angles that add to 180 degrees.

Let's examine the answer choices.

A. ∠8 and ∠7

⇒ These angles are on a straight line together, so they are supplementary.

B. ∠5 and ∠1

⇒ These angles have no relation to each other. They are on different lines that are not parallel.

C. ∠7 and ∠4

⇒These angles also have no relation to each other.

D. ∠2 and ∠4

⇒ These angles are vertical, but not supplementary.

The correct answer is A. ∠8 and ∠7

Answer:

Both RSA and AST measure 27.1

Step-by-step explanation:

Since SA, "bisected" (split in half by equal parts) angle RST, the RSA and AST is equal

therefore 54.2 / 2 =27.1

Bisect- means the segment halved/split the angle into 2 equal parts

Answer:

The situation of balloon B

Step-by-step explanation:

Balloon A is released 5 feet above the ground and our ground level be 0 feet. Let k be the rate at which it rises and t the time it takes to rise. Its height y, above the ground after time x is y = kt + 5

For Balloon B since it is released at ground level at which ground level is taken as 0 feet, let t be the time it takes to rise above the ground and k the rate at which it rises above the ground. Its height y above the ground after tie x is y = kt

Since the expression for Balloon B is y = kt and the expression for Balloon A is y = kt + 5, only the situation of Balloon B can be expressed in the form y = kx.

This is because the rate of rise of Balloon B follows a direct proportionality while the rate of rise of Balloon follow a joint proportionality since it starts from a point other than ground level.

Answer:

2

Step-by-step explanation:

Since the absolute value of -8 is 8, and the absolute value os 6 is 6, we can

do 8-6=2.

Answer:

We know that in a parallelogram two opposite angles are equal -

[tex] \\ \implies \sf \: 2x + 2y = 360 {}^{ \circ} \\ \\ \\ \implies \sf \: x + y = 180 {}^{ \circ} \qquad \quad \: (i) \\ [/tex]

Given -

[tex] \\ \implies \sf \: x = \frac{2}{3} y \\ \\ \\ \implies \sf \frac{x}{2} = \frac{y}{3} = k \\ \\ \\ \qquad \sf \small \underline{ x = 2k \: \: \& \: \: y = 3k} \\ [/tex]

Now, by using equation (1) :

[tex] \\ \implies \sf \: 2k + 3k = 180 \\ \\ \\ \implies \sf \: 5k = 180 \\ \\ \\ \implies \sf \: k = \frac{180}{5} \\ \\ \\ \large{ \boxed{ \sf{k = {36}^{ \circ} }}} \\ [/tex]

Now, by putting the value of k in x and y.

Therefore, the right option and smallest angle is b) 72°.

Answer:

p(- 3) = 0

Step-by-step explanation:

Substitute x = - 3 into p(x) , that is

p(- 3) = - 12(- 3) - 36 = 36 - 36 = 0

Answer:

(12 + 3x)x

Step-by-step explanation:

(12 + 3)x = 12x + 3x = 15x

(12 + 3x)x = 12x + 3x²

15x

12x + 3x = 15x

They all equal 15x except for (12 + 3x)x

The crop

Step-by-step explanation:

As the type of fertilizer changes it can not be the independent variable. Since nothing else (except the farmer) is referenced we can deduct that the crop is the independent variable.

Answer:

Step-by-step explanation:

g(x) = x² + 2

To find g(3) , substitute the value of x that's 3 into g(x) , that is for every x in g (x) replace it with 3

That's

g(3) = 3² + 2

= 9 + 2

We have the final answer as
