Some please help!! I will give brainliest

Step-by-step explanation:

-6 < 3x - 12 <= 9

6 < 3x <= 21 (add 12)

2 < x <= 7 (divide by 3)

The graph that correct represents this solution set is the 2nd graph.

Answer:

Step-by-step explanation:

The answer is 10 because 7 + 3 equals 10!

This can be proven by adding 7 + 3 or by subtracting in a certain way.

7 + 3 = ?

7 + 1 = 8

7 + 2 = 9

7 + 3 = 10

You can show more work by subtracting your answer or 10 in this case, which means that you subtract 7 by 10 or 3 by 10, either way is ok.

If you subtract 7 by 10, ( 10 - 7 ) then you get 3

If you subtract 3 by 10, ( 10 - 3 ) then you get 7

If the number you subtracted matches the number that you didn't subtract, then your answer is correct.

Step-by-step explanation:

.......

Answer:

B

Step-by-step explanation:

x + y = 90

Your x and y will give you a sum of 90

y= 4x + 6

Your y will be 6+ more then 4 TIMES x

therefore you would do 4 times x plus 6 equals y

Answer:

Approximately 18 years

Step-by-step explanation:

Triple: 997.90*3. which is 2993.7

997.90*0.17*x=2993.7

(x is time)

169.643x=2993.7

x=2993.7/169.643

x= approximately 17.64....... years/

18 years.

Hope this helps plz hit the crown :D

Answer:

4.79 dollars.

Step-by-step explanation:

7x + 3.62 = 37.15

7x= 37.15-3.62

7x=33.53

x= 33.53/7=4.79 dollars.

Answer:

C

Step-by-step explanation:

Expand the factors and compare the coefficients of like terms.

Given

(mx + 2)(3x - 5) ← expand using FOIL

= 3mx² - 5mx + 6x - 10

Compare to 12x² - 14x - 10

For the 2 to be equal, then the coefficients of like terms must be equal.

Compare coefficients of x² terms

3m = 12 ( divide both sides by 3 )

m = 4 → C

Answer:5

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given quadratic function is,

f(x) = -x² - x + 1

Range of the function has been defined as (-∞, [tex]\frac{5}{4}[/tex] ]

Domain of the function is a set of all real numbers.

From the graph of this function,

At x = -3 and x = 2, value of y = -5

But for one to one functions, every x value should map to a different value of y.

Therefore, function is not one to one.

Since, every value of domain (x-value) maps the range (y-value) in the given range (-∞, [tex]\frac{5}{4}[/tex] ], function will be defined as onto.

Therefore, this function is ONTO, but NOT ONE TO ONE.

Answer:

f(x) = 3(x-5) + 2

Step-by-step explanation:

The x coordinates are all shifted to the right, which is the positive direction. Subtracting 5 from the x coordinate is a horizontal right shift.

30% off means they are paying 70% of the original price.

Sale price = 2.40 x 0.70 = $1.68 for 10 plates

50 plates /  10  = 5

They buy 5 packages of plates.

1.68 x 5 = $8.40

Total price = $8.40

Answer:

Step-by-step explanation:

2.40 X 5 =$12

12 X 0.3=$3.6 off

12-3.6=$8.40

Therefore it'll cost $8.40

Answer:

W = 10 cm

Step-by-step explanation:

Area of a Triangle and a Rectangle

The area of a triangle of base B and height H is:

[tex]\displaystyle A_t=\frac{BH}{2}[/tex]

The area of a rectangle of width W and length L is:

[tex]A_r=WL[/tex]

We are given the base of the triangle B=6 cm and the height H=8 cm, thus the area is:

[tex]\displaystyle A_t=\frac{6*8}{2}= 24\ cm^2[/tex]

The area of the rectangle is 5 times the area of the triangle, thus:

[tex]A_r=5*24\ cm^2=120\ cm^2[/tex]

If we know the area of the rectangle and its length, we can find the width by solving for W:

[tex]\displaystyle W=\frac{A_r}{L}[/tex]

The rectangle has a length of L=12 cm, thus:

[tex]\displaystyle W=\frac{120}{12}=10\ cm[/tex]

W = 10 cm

Answer:

66.25 fluid ounce

Step-by-step explanation:

Given that :

Capacity of original container = 53 fluid ounces

Percentage addition of new container = 25%

Capacity of new container :

Capacity of original container * ( 1 + percentage addition)

53 * ( 1 + 0.25)

53 * (1.25)

= 66.25 fluid ounce
