Answer:

C

Step-by-step explanation:

Solving the inequality

x - 5 < 7 ( add 5 to both sides )

x < 12

None of the given values in the set are less than 12

Then solution is option C

Answer:

3 ( 917 ) = 3 ( 900 ) + 3 ( 10 ) + 3 ( 7 )

5 ( 209 ) = 5 ( 200 ) + 5 ( 0 ) + 5 ( 9 )

6 ( 347 ) = 6 ( 300 ) + 6 ( 40 ) + 6 ( 7 )

9 ( 821 ) = 9 ( 800 ) + 9 ( 20 ) + 9 ( 1 )

11 ( 142 ) = 11 ( 100 ) + 11 ( 40 ) + 11 ( 2 )

Step-by-step explanation:

Answer:

Hint(look at the first number in each part and math it with the first number in each answer.) For example, 3(937), the distributive property for that one would be 3(900) + 3(30) + 3(7). Then for 5(209) it would be 5(200) + 5(0) + 5(9), then for 6(342), it would be 6(300) + 6(40) + 6(2). Then for 9(821), it would be 9(800) + 9(20) + 9(1), and for the last one it would be 11(143), it would be 11(140) + 11(40) + 11(3). You basically distribute each amount into different place values.

The fraction 3/5 means that every hour, the amount of chemical increase by a factor of 3/5.

The domain of the function is (0, ∞) and the range is (600, ∞)

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

Let g represent the amount of a chemical in a persons body in milligrams t hours since the patient took the drug.

[tex]g(t) = 600(\frac{3}{5} )^t[/tex]

The fraction 3/5 means that every hour, the amount of chemical increase by a factor of 3/5.

The domain of the function is (0, ∞) and the range is (0, 600)

Answer:

[4]x+[8]=[1×]+2

Step-by-step explanation:

x will be negative now that the more x you have the higher your number will have to be.

The requried, x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution as x = -3.5.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
One possible solution is,

[1]x + [2] = [3]x + [9]

To see that this equation has a negative solution, we can rearrange it to get:

x + 2 = 3x + 9

x - 3x = 9 - 2
-2x = 7
x = -3.5

Since x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution.

Answer:

a) Each individual act will last 5 minutes.

b) Each group act will last 10 minutes.

Step-by-step explanation:

I think this is right

3(6x+2) <9

Use distributive property:

18x + 6 < 9

Subtract 6 from both sides

18x < 3

Divide both sides by 18

X < 3/18

Simplify:

X < 1/6

Answer:

x >= 7 OR x < -8

n <= -3 AND n > -6

Step-by-step explanation:

15) 7x - 6 >= 43 OR 10x + 4 < -76

7x >= 43 + 6 OR 10x < -76 - 4

7x >= 49 OR 10x < -80

x >= 7 OR x < -8

you can draw based on this

for >= it is full dot for < it is like circle on the graph

you have to draw both x>= 7 , x < -8 on the same line because it is OR

so both ranges of x are possible

21) 3 + 2n <= -3 AND 1 - 3n < 19

2n <= -3 -3 AND -3n < 19 - 1

2n <= -6 AND -3n < 18

n <= -3 AND 3n > -18

n <= -3 AND n > -6

so it lies between -6 and -3

Answer:

A

Step-by-step explanation:

The entire circle has an area of pi * r^2

r = 10

pi = 3.14

Area = 3.14 * 10^2

Area = 314 cm^2

But that is the whole circle. What is shaded is 1/4 of the circle which 314/4

which = 78.5 cm^2

Answer: A

Answer:

A) 78.5 cm^2

Step-by-step explanation:

1. To find the shaded part of the circle (1/4), we can use a formula similar to the one we use to find the area of a whole circle, but in this case, for the 1/4 part that's shaded: [tex]\frac{1}{4} \pi r^2[/tex]. Keep in mind that pi is approximated to 3.14.

2. (Solving)

Step 1: Plug in the values.

Step 2: Simplify.

Therefore, the answer is A) 78.5 cm^2.

Answer:

Step-by-step explanation:

Answer:

2 sides are [tex]\frac{33}{13}[/tex] or 2.5

2 sides are [tex]\frac{47}{13}[/tex] or 3.6

Step-by-step explanation:

There must be 2   2x+3s  and 2   3x+2s

The perimeter is the sum of the sides (it has 4 sides)

2(2x+3) + 2(3x+2) = 4(4x-5)

distributive property

2*2x + 2*3

4x+6

other one

2*3x + 2*2

6x+4

perimeter

4*4x + 4*-5

16x-20

together...

(4x+6) + (6x+4) = 16x-20

add like terms

10x+10 = 16x-20

add 20 to both sides

10x+30 = 16x

subtract 10x from both sides

30 = 26x

divide by 26 on both sides

[tex]\frac{30}{26} = x[/tex]

simplify

[tex]\frac{15}{13}[/tex]

Substitute the x value

2 of the sides are 2x+3

so

[tex]2(\frac{15}{13} ) + 3[/tex]

[tex]\frac{30}{13} + \frac{3}{1}[/tex]

[tex]\frac{33}{13}[/tex]

or 2.5

other sides

[tex]3(\frac{15}{13} ) + 2[/tex]

[tex]\frac{45}{13} + \frac{2}{1}[/tex]

[tex]\frac{47}{13}[/tex] or 3.6

That's all I can say for now! Hope this helps and a thank won't hurt! :)

Answer:

1. = station A

because 15 gallons = 0.75 discount at B but station A has a 1.50 discount at 15 gallons

Step-by-step explanation:

2. for satation B you have to read the graph

but for station A it is unclear on the graph

a way to work it out is that you know that 10= 1.00 so 12 = 1.2

( divide 12 by 10 )

station B = discount for 12 gallons = 0.6

but Station A = discount for 12 gallons = 1.2

the difference is

1.2 - 0.6 = 0.6 discount

Answer:

7x + 2y = 1

Step-by-step explanation:

1. Find the slope of the line.

(y2-y1)/(x2-x1) ---->  (11 - (-3))/((-3) -1) ----> (11+3)/ (-3 -1) ----> 14/-4

*lets simplify into (7/-2)*

2. Write into slope intercept form.

y=mx+b (m is the slope) (b is the y intercept)

y = (7/-2)x + b

We now need to find the value of b, this can be done by plugging in values of x and y, and using algebra to solve.

11 = (7/-2)(-3) + b

11 = 10.5 + b

b = 0.5 or 1/2

slope intercept form y = (7/-2)x + 1/2

Now we convert to standard form: ax+by=c

*In this form we our a term cannot be a fraction nor can it be negative*

1. Get x and y on the same side, and since our x term is negative right now, we can make it positive by adding it on both sides.

(7/2)x + y = 1/2

2. We now want to get rid of the fraction in term a, so we multiply the entire function by two, so the denominator cancels out.

2(7/2)x + 2y = 2(1/2)

Simplify and you get

7x + 2y = 1
