Answer: 36

Step-by-step explanation: If you're asking what the expression equals after plugging X's value in, this should leave you with an expression of -3^2 - 5(-3) + 12. By following the order of operations, you should receive an answer of 36.

Answer:

Line 1: Undefined

Line 2: -4/3

Line 3: 4/3

Line 4: Undefined

Line 5: 7/3

Line 6: -7/3

Line 7: 0

Line 8: 0

Line 9: Undefined

Line 11: 0

Line 10 & 12: Undefined

Step-by-step explanation:

Use the slope formula (you can just search up the slope formula)

Also, always remember that a vertical line's slope will be undefined and a horizontal line's slope will be 0 (zero).

I hope this helps!

Answer:

x=180

Step-by-step explanation:

Step-by-step explanation:

the equation completed is

1/2 (104 + 256) = 180

104+256 is 360.

360 multiplied by 1/2 (or 0.5) is 180.

Answer:

c=5,x=18/5 or 3.6

Step-by-step explanation:

Answer:

62%

Step-by-step explanation:

Given the information :

224 visitors purchased no costume.

103 visitors purchased exactly one costume.

32 visitors purchased more than one costume.

Based on these results, express the probability that the next person will purchase no costume as a percent to the nearest whole number.

Probability that next person will purchase no custome:

Probability = no of successes / total number of trials

Total number of trials :

(purchase no custome + purchase exactly one + purchase more than one)

= (224 + 103 + 32) = 359

Hence, Probability that next person will purchase no custome:

= 224 / 359

As a percentage :

(224 / 359) * 100%

= 0.6239554 * 100%

= 62.39 %

= 62% ( nearest whole percent)

Step-by-step explanation:

Population density is:

Correct option is A

Answer:15 times

Step-by-step explanation:

For the 3 batches it is 3 x 5/4 (5/4 is how much each batch costs)=15/4

And you must divide 15/4 by 1/4 or multiply it by 4 crossing out the denominator giving you your answer 15

Answer:

[tex]3(2x + 1) = 5(x -4) \\ 6x + 3 = 5x - 20 \\ 6x - 5x = - 3 - 20 \\ \boxed{x = - 23}[/tex]

come on this is simple division, thx for the points though

Answer:

[tex]14.2857[/tex] % of a weeks visitor come to the website on an average day

Step-by-step explanation:

Visitors on the website per day [tex]= 800[/tex]

Visitor on the website in seven day [tex]= 800*7[/tex]

Percent of visitor on any average to the total visitors in a week

[tex]= \frac{800}{800*7} *100\\= \frac{100}{7}\\= 14.2857[/tex]

Answer:

B (-1, 0)

Step-by-step explanation:

( in portuguese )

o ponto médio é calculado pela soma das abcissas a dividir por 2 e pela somas das ordenadas a dividir por 2, então sendo que se sabe o valor final, e um ponto fica :

(1+x)÷2 = 0 ⇔ x = -1

(1 + y) ÷ 2 = 1/2⇔ y=0

Answer:

m∠1=66

m∠3=66

m∠4=114

Step-by-step explanation:

m∠1+m∠2=180

m∠1+114=180

m∠1=66

m∠1=m∠3

66=m∠3

m∠4=m∠2

m∠4=114

Answer: x = 4

Step-by-step explanation:

since it is showing us that the angles are congruent, we know that the smaller triangle is just a scaled-down version of the larger one. in other words, it is the EXACT SAME triangle, just slightly smaller.

so, i redrew them next to each other, so i could compare them easily.

i looked at the corresponding sides that were given, and realized that the side that is 10 on the larger triangle is equal to 5 on the smaller triangle. the side that is equal to 6 on the larger triangle is equal to 3 on the smaller triangle. this concludes that the smaller triangle is exactly half the size of the larger triangle!

so, i figured (using logic) that x must equal 4, simply dividing its corresponding side (with a measure of 8) in half.

Answer:

It will take approximately 17 years

Step-by-step explanation:

Let the initial investment be x

The investment plus the principal yields 3x

The interest is thus 3x-x = 2x

Formula for simple interest is;

I = PRT/100

R is rate = 12%

T is time = ?

x =$2,000 which is the principal

2x = x * 12 * T/100

2 = 12t/100

12t = 200

t = 200/12

t = 16.67 which is approximately 17 years

Answer:

a or the first one

Step-by-step explanation:

x - 1 ≤ 6

add 1 to both sides

x ≤ 7

the ≤ is pointing <<< that way

so the line will go on the left side of seven

and since its greater than or equal to its a closed circle
