Answer:

babysitting = $9

working at coffeehouse = $12

x = hours for babysitting

y = hours at coffeehouse

minimum = ≥

9x + 12y ≥ 240

Step-by-step explanation:

just a short note on which symbol you should use when you see these words in inequality questions:

i) use ≥

-more than or equal to

-not less than

-at least

-minimum

ii) use >

-more than

-greater than

iii) use ≤

-less than or equal to

-not more than

-at most

-maximum

iv) use <

-less than

The inequality 9x + 12y ≥ 240 represents that Rachael wants to earn a minimum of $240 if she earns $9 per hour babysitting, and she earns $12 per hour working at the coffee-house.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

Rachael earns $9 per hour babysitting, and she earns $12 per hour working at the coffee-house.

x is the number of hours babysitting.

y is the number of hours at the coffee-house.

9x + 12y ≥ 240

Because, Rachael wants to earn a minimum of $240.

Thus, the inequality 9x + 12y ≥ 240 represents that Rachael wants to earn a minimum of $240 if she earns $9 per hour babysitting, and she earns $12 per hour working at the coffee-house.

Answer:

the answer is D

Step-by-step explanation:

√-9 ≠ -3

-3 ≠ √-9

(-3)² ≠ -9 ( proven )

9 ≠ -9

The value √-9 ≠ -3², option D is correct answer.

An imaginary number is a number that, when squared, has a negative result.

Given an expression, √-9

√-9 ≠ -3

-3 ≠ √-9

(-3)² ≠ -9

9 ≠ -9

Hence, √-9 ≠ -3²

Answer:

-300

Step-by-step explanation:

z = -21/0.07

z = -300

Answer:

-300

Step-by-step explanation:

Divide -21 by 0.07 to get -300

Answer:

To find the answer, we simply have to substitute the values for a and b that the question gave us into the expression.

In this case, that would be substituting a = -1 and b = 2 into -3ab - 2.

[tex]-3(-1)(2) - 2[/tex]

[tex]= 3(2) - 2[/tex]

[tex]= 6 - 2[/tex]

[tex]= 4[/tex]

Hence, the answer is 4. However, there is no option with 4 for Question 3, so I would suggest OP to check the question again to confirm if there is no option with the answer as 4.

Answer:

I understand there is a typo, so Belly and Billy are the same person. His age is represented as B, and Suzy's as S.

S = 19

B = 9

Step-by-step explanation:

Suzy is ten years older than Belly:

(1)  S = B + 10

the next year she will be twice as old as Billy

(2)  S + 1 = 2 (B + 1)

solving the system of equation (1) and (2):

Making (2) - (1):  

1 = 2 (B + 1) - B - 10 => 1 = 2 B + 2 - B - 10  => 1 = B - 8 => B = 9

replacing in (1) S = 19

I just got confused sorry.

Answer:

68 degrees

Step-by-step explanation:

1 & 6 have to equal 180. Therefore, if 1 is 112 then you take 180-112. Then you get 68 degrees.

Answer:

Angle 6 would be 68 degrees

Step-by-step explanation:

Angles 1, 3, 5, and 7  all equal 112. you would subtract 112 from 180 to get the measurement for angles 2, 4, 6, and 8

Step-by-step explanation:
