Teena's calculator is broken and does not have key 9 that works! With this broken calculator she found out the value of (-35) x 99. Explain your reasoning carefully and clearly
Answer:
(-35) * (100 - 1)
Step-by-step explanation:
She was able to find the value of (-35) * 99 without using the missing 9 button on her calculator.
The easiest way to do this is to replace 99 with another set of numbers that has the same value as 99.
(100 - 1) has the same value as 99. So, Teena can replace 99 with (100 - 1):
(-35) * (100 - 1)
It will yield the desired result.

A. A worker with 1700 hours of training is paid $40 per month.
B. A worker who works 40 hours is paid $1700.
C. There are 40 workers who are paid $1700 per month.
D. A worker with 40 hours of training is paid $1700 per month
Answer:
d.
Explanation:
Look at the title of the categories in the chart. 40 is categorized under “hours of training,” meaning 40 hours of training. 1700 is categorized under “monthly pay.” Put the information together and it means $1,700 for 40 hours that month.

Please answer correctly quick !!!!!!!!!! Will mark brainliest !!!!!!!!!!
Answer:
see below
Step-by-step explanation:
first flip x and y and solve for y
write new equation as x =-3(y+6) distribute
x = -3y -18 add 18 on both sides
x +18 = -3y divide by -3
(-1/3) x -6 or (x +18)/-3 or [tex]\frac{-x}{3} -6[/tex]

HELP I DONT GET THIS AT ALL. ITS ABOUT INEQUALITIES EXPLANATION NEEDED
Answer:
Since the slope of the line is (31/4 - 25/4) / (5/4 - 3/4) = 3 that means that for every 1 that x increases, y increases by 3 so an example could be 1 3/4 for x and 9 1/4 for y.

From sea level, a submarine descends 40 feet per minute. Where is the submarine in relation to sea level 5 minutes after it starts descending?
Answer:
It is expected to be at a distance of 200 ft below the sea level
Step-by-step explanation:
We are told that the sub marine has a descending rate of 40 ft per minute.
Thus, after five minutes, the distance it would have descended would be 40 ft per minute * 5 minute = 200 ft
Thus, the submarine is expected to be 200ft below sea level

b.
27 sq. ft
c.
49 sq. ft
d.
126 sq. ft
Answer:
a. 63 ft²
Step-by-step explanation:
A= 1/2(b1+b2)h
b1= 14 ftb2= 7 fth= 6 ftA= 1/2(14+7)*6= 63 ft²Answer:
[tex]63 {ft}^{2} [/tex]
Answer A is correct
Step-by-step explanation:
[tex]area = \frac{1}{2} (a + b)h \\ = \frac{1}{2} \times (7 + 14) \times 6 \\ = \frac{1}{2} \times 21 \times 6 \\ = \frac{126}{2} \\ = 63 {ft}^{2} [/tex]

What is the domain of the function shown on the graph?
Answer:
Step-by-step explanation:
Looking at the arrows on the graph, it appears that as the graph keep growing UP unbounded, it also keeps growing to the left unbounded (to negative infinity, to be exact). Looking to the right, it appears that as the graph decreases unbounded (the y values keep getting smaller), the graph keeps growing in the x direct to positive infinity. So the domain is

I need help im lazy :)
Answer:
[tex]x=-8[/tex]
Step-by-step explanation:
→All you need to do for this equation is, divide both sides by -300. You do this to get "x," by itself:
[tex]2400=-300x[/tex]
[tex]\frac{2400}{-300} =\frac{-300x}{-300}[/tex]

If 4u-5v=23 and 2u+4v=-8, find the value of u+v
Answer:
-1
Step-by-step explanation:
4u-5v=23
-2(2u+4v=16) We multiply by -2 here to destroy u's.
4u-5v=23
-4u-8v=16 we addition both processes
-13v=39 so, v=-3
4u-5(-3)=23, 4u=8 so, u=2
u+v= -3+2= -1

What is the domain of f(x) = 3x – 2? {x | x > 0} {x | x < 0} {x | x = 0} {x | x is a real number}
Answer:
Option (4). {x | x is a real number}
Step-by-step explanation:
Domain of any function is defined by the x values (Input values) and range by the y-values (Output values).
Given function is f(x) = 3x - 2
When we graph this function, we get a straight line.
That means the given function is defined for all real numbers.
Therefore, domain of this function will be all real numbers.
Domain: {x | x is a real number}
Option (4) will be the answer.
Answer:
D) {x | x is a real number}
