Simplify : -sqrt(9+y)^2 if y<-10

Answer:

x = 3

Step-by-step explanation:

Taking this from the graph:

2x + 5 = 11

2x = 6

x = 3

Answer:     A) 3

Step-by-step explanation:

2x+5=11

2x=6

x=3

Answer:

Step 3.

Step-by-step explanation:

When you distribute this [tex](-3)(x-5)[/tex],

you should get [tex]-3x+(-3)(-5)[/tex].

However, [tex]-3*-5=15[/tex] and not [tex]-15[/tex] because of the double negative.

Answer:

115000

Step-by-step explanation:

25000 x .12 = 3000

3000 x 30 = 90000

90000 + 25000 = 115000

Answer: q= 30

Step-by-step explanation:

Solve for q

by simplifying both sides of the inequality, then isolating the variable.

Inequality Form:

q>25

Interval Notation:

Answer:

7 yd^3

Step-by-step explanation:

The Volume is:

V=a*b*c

a=7*(1/3) yd

b=3*(1/3) yd

c=9*(1/3) yd

So, V=7 yd^3

Answer:

1436.03 m³

Step-by-step explanation:

The formula of volume of sphere

[tex] = \frac{4}{3} \pi {r}^{3} [/tex]

The volume of the sphere

[tex] = \frac{4}{3} \times 3.14 \times {(14 \div 2)}^{3} [/tex]

[tex] = \frac{4}{3} \times 3.14 \times {7}^{3} [/tex]

[tex] = \frac{4308.08}{3} [/tex]

[tex] = 1436.0266667...[/tex]

= 1436.03 m³ (rounded to the nearest hundredth)

The volume is:

Correct choice is A

Answer:

Well to this you would have to simplify the ratio first

75:35:45

That can be

15:7:9

So that means thayt each troop would get 15 enegery bars, 7 drinks and 9 bottles of water

Well if you were to keep repeating that process or just do a proportion you would get 5 total troops.

15:7:9

75:35:45

15*5 is 75

7*5 is 35

9*5=45

So 5 troops

Answer:

B + 21

or

21 + B

Step-by-step explanation:

The sum of B and 21

The sum of : means to add B and 21

The algebraic expression would be: B + 21  or 21 + B (depending on how you/your teacher wishes it to be written)

Answer:

21 + b

Step-by-step explanation:

The answer to this expression is the sum of b and 21. The answer is 21 + b.

Good luck ^^

Answer:

f(X)=2x+3

Step-by-step explanation:

f(4) = 2*4 + 3

= 8 + 3

= 11

Answer and Step-by-step explanation:

For this function, we need to plug in 4 for x to find out what the value of f(x) is when x is equal to 4.

f(4) = 2(4) + 3

= 8 + 3

= 11

The answer is 11, when the value is f(4).

Step-by-step explanation:

Answer:

[tex] \huge\green{ \mid{ \underline{ \overline{ \tt ♡ ANSWER ♡ }} \mid}}[/tex]

There's no specific formula to find the square root of a number, however we can find the square root of a number by the following methods:

i) By Prime Factorisation

ii) By Long Division

iii) By Repeated subtraction method

Step I: Obtain the given number.

Step II: Reduce the given number into prime factors by successive division.

Step III: Now make pairs of prime factors in such a way that both the factors in each pair are equal.

Step IV: Take one factor from each pair and find the product of these factors.

Step V: The product obtained by multiplying the factors is the required square root.

Step 1: Firstly, we place a bar on every pair of digits starting from the unit digit. If the number of digits in it is odd, we put a bar on the single-digit too.

Step 2: Now we find the largest number whose square is less than or equal to the 1st number.

Step 3: Now we bring down the next bar number.

Step 4: For new divisor, we add the divisor & quotient.

Step 5: Number taken is the product of a new divisor and this digit is equal to or less than the new dividend.

In this method, the given number is subtracted by 1, 3, 5, 7,… at every step till you get zero at the end. The number of steps in the solution is the required square root.

For number 13, I think it is rational, integer, and whole number

Answer:

y = -2x + 4

Step-by-step explanation:

To write an equation in slope-intercept form, y = mx + b, we need to find the slope (m) and the y-intercept (b).

✔️Slope (m) using two pairs of values, (0, 4) and (1, 2):

Slope (m) = change in y/change in x

m = (2 - 4)/(1 - 0) = -2/1

m = -2

✔️y-intercept is the value of y when x = 0. Therefore, fromm the table, when x = 0, y = 4.

y-intercept (b) = 4

✅Write the equation by substituting m = -2 and b = 4 into y = mx + b:

Thus,

y = -2x + 4

Answer:

r^4+h

Step-by-step explanation:

5 Students = 3 Teams

7 Students = 2 Teams

To find out the answer we can use the following equation

[tex]\frac{Total}{Students} \\\\\frac{15}{5} = 3 \\\frac{15}{7} = 2.14... \\[/tex]

If you run into a decimal number, like we did when we had a team of 7, you can just round down!

Answer:

3

Step-by-step explanation:

least students= 5

maximum students = 7

total number of students = 15

no: of grps if 5 students per grp = 15/5 = 3

no: of grps if 7 students per grp = 15/7 = 2.14 ~ 2

However, if they ask us how many teams in final we can say 3 as it is the maximum number of groups that can be formed b a grp of 15 students ... if we make 7 students per grp... one would be left out .

Answer:

the perimeter is 30ft

Step-by-step explanation:

a square + b square = c square

so first we find your missing side

this is how we solve for that:

a square + 12 squared = 13 squared

a squared + 144 = 169

now we do 169 - 144 = 25

now to find the missing side it is 25 square root which is 5

now that we have found the missing side lengths let's find the perimeter which is: 5 + 12 + 13 = 30 ft

I hope this helped!
