Solve for x <br> 6x+3y=54<br> 2x+y=18

butalik [34]

Step-by-step explanation:

6x+3y=54

- 2x+y=18

I'm going to be using the elimination method cause it seems easiest here. so for the elimination method u choose a variable to eliminate I chose y u could do x too if u want to. so first step would be to multiply the second equation by 3. 6x+3y=54

so now u just have to eliminate

6x+3y=54

- 6x+3y=54

because these cancel out the answer would be an infinite solution

Six football players, all defensive linemen, decide that they'll gain an average of 10 pounds over the summer. At the start of t

noname [10]

Answer: b. 14 pounds

Step-by-step explanation:

Formula to calculate average :

$\text{Average}=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}$

Let x denotes the number of pounds the last person have to gain so that the group can attain its goal.

Required average = 10 pounds

Observations = 9, 13, 11, 6, 7 and x (pounds)

Number of observations= 6

Sum of all observations = 9+13+ 11+ 6+7+x=46+x

According to the question , we have

$10=\dfrac{46+x}{6}\\\\ 46+x=10\times6\\\\ 46+x=60\\\\ x=60-46=14$

i..e the last person has to gain 14 pounds so that the group can attain its goal.

Hence, the correct answer is b. 14 pounds .

for In the given expression, calculate as indicated. Express your answer as a single polynomial in standard form. 4x^(3)-2x^(2)

matrenka [14]

Answer:

The polynomial in standard form is $y = 14 + 6\cdot x - 8\cdot x^{2}+4\cdot x^{3}$ .

Step-by-step explanation:

A polynomial in standard fulfills the following condition:

$y = \Sigma_{i=0}^{m}\,c_{i}\cdot x^{i}$ , $\forall\,i\in \mathbb{N}$ , $0 \leq i \leq m$

Let be $y = (4\cdot x^{3}-2\cdot x^{2}+9)-(6\cdot x^{2}-6\cdot x + 5)$ , which is now handled algebraically:

1) $(4\cdot x^{3}-2\cdot x^{2}+9)-(6\cdot x^{2}-6\cdot x + 5)$ Given

2) $(4\cdot x^{3}-2\cdot x^{2}+9) +(-1)\cdot (6\cdot x^{2}-6\cdot x + 5)$ $(-1)\cdot a = -a$

3) $(4\cdot x^{3}-2\cdot x^{2}+9) +[(-1)\cdot (6\cdot x^{2})+(-6\cdot x)\cdot (-1)+5]$ Definition of substraction/Distributive property

4) $(4\cdot x^{3}-2\cdot x^{2}+9)+(-6\cdot x^{2}+6\cdot x + 5)$ $(-1)\cdot a = -a$ / $(-a)\cdot (-b) = a\cdot b$

5) $4\cdot x^{3}+ (-2\cdot x^{2}-6\cdot x^{2})+6\cdot x + (9+5)$ Associative and commutative properties

6) $4\cdot x^{3}-8\cdot x^{2}+6\cdot x + 14$ Distributive property/Definition of addition

7) $14 + 6\cdot x -8\cdot x^{2}+4\cdot x^{3}$ Commutative property/Result

The polynomial in standard form is $y = 14 + 6\cdot x - 8\cdot x^{2}+4\cdot x^{3}$ .
