what is the rule for solving any equation?
A. just look at it and it will be solved
B. always add the numbers
C. Do the inverse or opposite operations
D. the is no rule for solving equations
Answers
Answer:
C) Do the inverse or opposite operations
Step-by-step explanation:
Take for example the equation 4=2x. Because 2 is being multiplied by x, the only way for x to get by itself is to do the opposite operation; dividing both sides by 2 to get 2=x.

In a survey of U.S. Adults, 16% say they have had someone take over their email accounts without their permission. You randomly select 250 U.S. Adults and asked them whether they have had someone take over their email accounts without their permission. Find the probability that the number of U.S. Adults who say they have had someone take over their email accounts without their permission is : a. At most 40 b. Less than 45 c. Exactly 48
Answers
Answer:
a. At most 40
Step-by-step explanation:
If we take the survey that was done as a basis then we would use the 16% that was obtained as the number of overall US adults that have had their accounts used without their permission. Assuming that the 250 selected individuals were selected at random and without bias then those 250 would also be representative of the entire population. Therefore, we would simply need to multiply the number of selected individuals by the percentage in decimal form.
16 / 100 = 0.16
250 * 0.16 = 40
Finally, we can see that roughly 40 individuals would have had their email used without permission.

An object moves around x + y = 25 (which represents a
circle whose radius is 5 meters) at a constant speed. At time
t = 0 seconds, the object is at (5,0). When t = 1, it is at (4,3). Where is the object when t = 2? When t = 3? when t = n?
What is the object’s speed? At what times does the object return to (5, 0)? To arrive at your answers, what assumptions did you make?
Answers
Answer:
Step-by-step explanation:
There is an error in the question.
x + y = 25 is NOT the equation of a circle.
It should be x^2 + y^2 = 5^2.
Parametric equations for the circle:
x = 5cosθ
y = 5sinθ
After 1 second, the object is at (4,3), so θ=arctan(3/4).
At 2 seconds, θ=2arctan(3/4). The object is at (5cosθ,5sinθ) = (1.4, 4.8).
At 3 seconds, θ=3arctan(3/4). The object is at (-1.76, 4.68).
360°/arctan(3/4) ≈ 9.764
The object returns to (5,0) after 9.764 seconds.

A. I
B.-1
C.-2
D. 2
Answers
Answer:
x = -2 is a function
Step-by-step explanation:
To get which is a zero, we have to look at one value of x which when substituted into the polynomial will give -1
we have this as:
Let us try the value x = -2
-2^5 + 2(-2)^4 - 2 + 2
= -32 + 32 - 2 + 2 = 0
This means that the term x = -2 is a root of the equation

Answer:
x = 29.4
y = 17
Step-by-step explanation:
sin 90° / 34 = sin 60° / x
x = 34·sin 60°
x = 29.4
sin 90° / 34 = sin 30° / y
y = 34·sin 30°
y = 17

Juan sells a boat that he bought 5 years ago. He sells it for 60% less than he originally paid for it. If the original cost is b, write an expression that shows how much he sells the boat for
Answers
Answer:
b - 0.60b
= 0.40b
Step-by-step explanation:
The expression would be
here the original cost is b
And Juan sells it for 60% less than original price
So the expression is
= b - 0.60b
= 0.40b
This would be the expression that shows the selling price of the boat

• 66
• 175
• 125
• they will never cross
Answers
Firstly the best thing to do is create two different equations.
1. y=25+.08x
2. y=20+.12x
Then you plug into Desmos and see at what point they cross. They cross at (125, 35).
Therefore for 125 text messages would cost 35$ for each plan.
A tree grows 2 inches per year. It was 14 inches tall when it was planted. what would be this function discrete continuous or neither? whould it be a linear an exponential or neither? what would be the domain?
please help greatly appreciated
Answers
Answer:
This function is a continuous linear function that's domain is all positive real numbers.
Step-by-step explanation:
This function is continuous because every linear function is continuous and this function is the linear function y = 2x+14 where x is the years it has been planted and y is the height.
It is a linear function, it's hard to explain, but it has a dependent variable, the height of the tree that changes at a constant rate with the independent variable which is time in years.
The domain is all positive real numbers since time/years can not be negative.
A large field measures 70 feet by 525 feet. If you divide it up into equal square garden plots, what size would the largest possible plot be with sides of whole number length?
Answers
9514 1404 393
Answer:
35 feet square
Step-by-step explanation:
The greatest common factor of 70 and 525 is 35. The largest square plot can be 35 feet on a side.
70 = 2·35
525 = 15·35

I like to find the GCD (greatest common divisor) using Euclid's algorithm. We find the remainder when dividing the larger by the smaller. When that remainder is not zero, we replace the larger number with the remainder, and repeat. When the remainder is zero, the divisor is the GCD.
525/70 = 7 r 35
70/35 = 2 r 0 . . . . . 35 is the GCD

1. Think of two things that you can measure. Give one that requires high precision, or a low level of uncertainty. Give another that can have lower precision, or a higher level of uncertainty.
2. Explain why you made your choices. Why does one measurement need to be more precise than the other?
Answers
Problem 1
Two things you could measure is a person's height and the speed needed to reach the planet Mars. The person's height can be measured with a low level of precision, which means we don't need to be that accurate. We could say "that person is about 6 feet tall" and whoever is listening would get a sense of their height. In contrast, we need high precision for a rocket speed to Mars because getting this figure wrong would likely cause disaster down the road. Very complicated mathematics is essential to make sure we hit the target required in space.
===============================================
Problem 2
As mentioned, we need high precision when it comes to anything dealing with space travel. If the calculations are wrong, then the spacecraft could crash somehow. As one example where things went wrong, engineers used the wrong values and the Mars lander ended up crashing into the planet rather than landing safely. The high cost of such space exploration missions means that it's very crucial to get precise values as much as possible, to as accurate as possible. Things like discussing a person's height isn't that essential to be very precise as we can just relay estimates to whoever we're talking to. This informal setting doesn't demand as much accuracy compared to something like a rocket launch.

Answer:
x is less than or equal to negative 14.
Step-by-step explanation:
so for now we should pretend that the greater than or equal to is an equal sign, and simplify the problem to get x alone on a side
remove 5 from each side
-x/3=1/3-5
-x/3=14/3
multiply both sides by 3
-x=14
x=-14
so we can now replace the equal sign with the equal or greater to, so x is less than or equal to -14
