Someone please help me with these or at least tell me how it works

Answer:

x=-2

Step-by-step explanation:

2 = 3x+14/4

2x4 = 4x4    4 cancels

8 = 3x+14

8-14 = 14-14    14 cancels

-6 = 3x

-6/3 = 3/3   3 cancels and you're left with x

-2=x

Answer: They had 24 items for the sale.

Step-by-step explanation:

Given: In baking sale,

18 different people made 2 dozen items for the sale.

We know that,

1 dozen = 12 items

2 dozens = 2 x 12 items

i.e. 2 dozens = 24 items

Therefore, they will have 24 items for sales if they made 2 dozens items.

Hence, they had 24 items for the sale.

Answer:

24 items for the sale.

I did the worksheet

Answer:

27 /35

Step-by-step explanation:

Para sumar fracciones, busque el LCD y luego combinar.

[tex]7x + 12 = 9x - 6[/tex]

[tex]7x + 12 - 7x = 9x - 6 - 7x[/tex]

[tex]12 = 2x - 6[/tex]

[tex]12 - 6 = 2x -6 - 6[/tex]

[tex]6 = 2x - 12[/tex]

[tex]6 + 12 = 2x[/tex]

[tex]18 = 2x[/tex]

[tex]18 \div 2 = x[/tex]

[tex]9 = \bold{ x}[/tex]

In pythagoras, c is the hypotenuse. That is AC. Where a is AB and b is BC.

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

[tex] {(6 x + 5)}^{2} = {(7x + 12)}^{2} + {BC}^{2} [/tex]

[tex] {((6 \times 9) + 5)}^{2} = {((7 \times 9)}^{2} + 12)^{2} +{BC}^{2} [/tex]

[tex] {(54 + 5)}^{2} = {(63 + 12)}^{2} + {BC}^{2} [/tex]

[tex] {59}^{2} = {75}^{2} + {BC}^{2} [/tex]

[tex]3481 = 5625 + {BC}^{2} [/tex]

[tex]3481 - 5625 = {BC}^{2} [/tex]

[tex] - 2144 = {BC}^{2} [/tex]

[tex] \sqrt{ - 2144} = BC[/tex]

Answer:

A= (1/2)(X)(2X)

(1/2)(2X^2)

= (2X^2)/2

Answer:

The domain of the function is represent by all values of  equal or greater than zero.

The given function is based on the assumption that the greater the family, the lesser the income mostly because the number of siblings, and therefore, the higher the financial aid.

Step-by-step explanation:

Let f(x)=25000+3000 x x , where  is the number of siblings of the student, dimensionless, and  is the financial aid for the student, measured in US dollars.

represents the domain of the function, whose set is formed by non-negative entire numbers:

In other words, the domain of the function is represent by all values of  equal or greater than zero.

Besides, the given function is based on the assumption that the greater the family, the lesser the income mostly because the number of siblings, and therefore, the higher the financial aid.

Answer:

Answer is 4/5

Step-by-step explanation:

=3/5(7x+10)=14

=21x/5+53/5=14

=21x/5=14-53/5

=21x/5=3.4

=x=3.4×5/21

=x=0.8 or 8/10=4/5

Answer:

3,400 g

Step-by-step explanation:

The computation of the grams of trail he left is shown below:

As we know that

1 kg = 1000g

So for 12 kg it is = 12000 g

And, his family ate 8,600 g mix on the hiking trip

So, the trial mix did he have left is

= 12,000 g - 8,600 g

= 3,400 g

Answer:

Step-by-step explanation:

No this is not proportional , because the ratio of y/x for each one is not same ,

As for 1st one ,

y/x =4/2 =2

for 2nd one ,

y/x=16/4 = 4 and so on

so they re not equal that's why they are not proportional

Answer:

Your answer is.......

x^3 + 2x^2 + 4x + 8=0 Note.. if x=-2 then whole equation is 0

So, (x+2) is one factor.

x^3 + 2x^2 + 4x + 8

=x^2(x+2)+4(x+2)

(x+2)(x^2+4)

Mark my answer as brainlist. pls pls pls

Answer:

(-2,-14), (0, -8), (2, -2), (4, 4)

Step-by-step explanation:

Plug the x-value into the equation to get the corresponding y-value.

Example: Want the y-value for -2?

y = 3(-2) - 8

y = -6 - 8

y = -14

y-value for 2?

y = 3(2) - 8

y = 6 - 8

y = -2

Repeat that for all values.

Hope this helped!

Answer:

Step-by-step explanation:

[tex]\frac{6}{\frac{3}{4}}\\ \\ 6\left(\frac{4}{3}\right)\\ \\ 8\ pieces[/tex]

The answer is.

y = 2, x = -4

Answer:

x=-4

Step-by-step explanation:

First substitute y=3x+14

2x-3(3x+14)=-14

Distribute:

2x-9x-42=-14

Add or subtract like terms

-7x-42=-14

-7x=28

Finally divide both sides by -7

-7x/-7=x

28/-7=(-4)

x=-4

Answer:

17 to 24

25 to 32

Step-by-step explanation:

8-1=7

16-9=7

therefore it means we add 7 on the next number which is 17; to get 24,and also to the next number after 24 which is 25 to get 32

Answer: 17 to 24 then 25 and 32

Seriously Stephanie u needed help with this? Anyways glad I can help.

Answer:

the y-values for the x-values, starting with -3, are:

-5, -4, -3, -2, -1, 0, 1

Step-by-step explanation:

for each, plug the x-value into the equation y = x - 2 and get the result

example, when x = -3 then y = (-3 - 2) which is -5

Answer:

$17.55

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 390 × 0.03 × 1.5 = 17.55

I = $ 17.55

The simple interest accumulated

on a principal of $ 390.00

at a rate of 3% per year

for 1.5 years is $ 17.55.

Answer:

Step-by-step explanation:

7 hr/3 pumps

So first we want to find the unit rate which would be...

5.25 hr/1 pump

Now that we found the unit rate we are going to multiply it by 2 because there are 2 pumps...

5.25*2=10.5

So our answer is 10.5 hr/ 2 pumps
