Answer:(1,-1)
Step-by-step explanation:
Y= -2x+1
3x -2(-2x*1)=5
3x+(4x-2)=5
7x-2 =5
+2 = +2
7x=7
x= 1
Solution : (1,-1)
A rubber ball bounces after it is dropped from a height of 212 feet, and it
continues to bounce one-half the height from which it last fell. How many
bounces does it take
before the ball falls less than one foot?
Answer:
C. 8 bounces
Step-by-step explanation:
To solve this, you can write an equation before turning it into an inequality:
y = 212*(1/2^x)
(x is bounces, y is height)
Now you can change it into an inequality to fit the height of less than 1:
1 > 212*(1/2^x)
In order for the right side of the equation to be less than 1, 2^x must be greater than 212 (because 212*(1/212) is 1, so if the denominator is greater, it'll be less than 1). 2^8 is 256, which is greater than 212, so that means x is 8.
Because x represents bounces, that means the ball's height will be under 1 foot after 8 bounces.
what is the equation for the line that passes through the given point and is parallel to the graph of y=2/3x+19; (-9, 4)
Answer:
Step-by-step explanation:
We're given the line
[tex]y = \frac{2}{3}(x) + 19[/tex]
The slope of the line is [tex]\frac{2}{3}[/tex]
We have to find another line with the same slope that goes through the point
[tex](-9, 4)[/tex]. We can solve this by using
[tex]y = mx + b\\y = \frac{2}{3}(x) + b\\4 = \frac{2(-9)}{3} + b\\4 = -6+ b\\b = 10\\\\y = \frac{2}{3}(x) + 10[/tex]

Last Friday Cicely had $22.50. Over the weekend she received some money for
cleaning out the attic. She now has $32. Which equation represents how much
money she received?
Answer:
It should be $32 - $22.50.
Step-by-step explanation:
This is because we're trying to find out the amount she received. So we will subtract the amount she already has from how much she now has to figure out how much she received. 32 - 22.50 = 9.50.

Which expression means the same as "subtract 3 from 7 and then multiply
by 4"?
Answer:
(7-3)x4
Step-by-step explanation:
Youre subtracting 3 from 7 so that means that 7 is first because your subtracting 3 and seven is the greater number, it says to then multiply by 4 so that means that you have to put parenthesis around 7-3 because you need to do them first. I hope this makes sense and answers your question! :)

6.324555320
Step-by-step explanation:
Here we will define, analyze, simplify, and calculate the square root of 40. We start off with the definition and then answer some common questions about the square root of 40. Then, we will show you different ways of calculating the square root of 40 with and without a computer or calculator. We have a lot of information to share, so let's get started!
Square root of 40 definition
The square root of 40 in mathematical form is written with the radical sign like this √40. We call this the square root of 40 in radical form. The square root of 40 is a quantity (q) that when multiplied by itself will equal 40.
√40 = q × q = q2
Is 40 a perfect square?
40 is a perfect square if the square root of 40 equals a whole number. As we have calculated further down on this page, the square root of 40 is not a whole number.
40 is not a perfect square.
Is the square root of 40 rational or irrational?
The square root of 40 is a rational number if 40 is a perfect square. It is an irrational number if it is not a perfect square. Since 40 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 40?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.
√40 is an irrational number
Can the square root of 40 be simplified?
You can simplify 40 if you can make 40 inside the radical smaller. We call this process "to simplify a surd". The square root of 40 can be simplified.
√40 = 2√10
How to calculate the square root of 40 with a calculator
The easiest and most boring way to calculate the square root of 40 is to use your calculator! Simply type in 40 followed by √x to get the answer. We did that with our calculator and got the following answer with 9 decimal numbers:
√40 ≈ 6.324555320
How to calculate the square root of 40 with a computer
If you are using a computer that has Excel or Numbers, then you can enter SQRT(40) in a cell to get the square root of 40. Below is the result we got with 13 decimals. We call this the square root of 40 in decimal form.
SQRT(40) ≈ 6.3245553203368
What is the square root of 40 rounded?
The square root of 40 rounded to the nearest tenth, means that you want one digit after the decimal point. The square root of 40 rounded to the nearest hundredth, means that you want two digits after the decimal point. The square root of 40 rounded to the nearest thousandth, means that you want three digits after the decimal point.
10th: √40 ≈ 6.3
100th: √40 ≈ 6.32
1000th: √40 ≈ 6.325
What is the square root of 40 as a fraction?
Like we said above, since the square root of 40 is an irrational number, we cannot make it into an exact fraction. However, we can make it into an approximate fraction using the square root of 40 rounded to the nearest hundredth.
√40
≈ 6.32/1
≈ 632/100
≈ 6 8/25
What is the square root of 40 written with an exponent?
All square roots can be converted to a number (base) with a fractional exponent. The square root of 40 is no exception. Here is the rule and the answer to "the square root of 40 converted to a base with an exponent?":
√b = b½
√40 = 40½
How to find the square root of 40 by long division method
Here we will show you how to calculate the square root of 40 using the long division method with one decimal place accuracy. This is the lost art of how they calculated the square root of 40 by hand before modern technology was invented.
Step 1)
Set up 40 in pairs of two digits from right to left and attach one set of 00 because we want one decimal:
40 00
Step 2)
Starting with the first set: the largest perfect square less than or equal to 40 is 36, and the square root of 36 is 6. Therefore, put 6 on top and 36 at the bottom like this:
6
40 00
36
Step 3)
Calculate 40 minus 36 and put the difference below. Then move down the next set of numbers.
6
40 00
36
4 00
Step 4)
Double the number in green on top: 6 × 2 = 12. Then, use 12 and the bottom number to make this problem:
12? × ? ≤ 400
The question marks are "blank" and the same "blank". With trial and error, we found the largest number "blank" can be is 3. Now, enter 3 on top:
6 3
40 00
36
4 00
That's it! The answer is on top. The square root of 40 with one digit decimal accuracy is 6.3.

Which of the following could be the equation of a line parallel to the line y = 4 ?
A- undefined
B- y=0
C- x=4
D- y=4x
Answer:
B
Step-by-step explanation:
y = 4 is a horizontal line parallel to the x- axis
A parallel line must also be horizontal with equation
y = c ( c is the value of the y- coordinates the line passes through )
The only equation in this form is
y = 0 ( the equation of the x- axis ) → B
Option B: [tex]y=0[/tex] is the equation of the line parallel to the line [tex]y=4[/tex]
The general equation of a line is [tex]y=mx+b[/tex] where, [tex]'m'[/tex] is the slope of the line and [tex]'b'[/tex] is the constant.
For a line to be parallel with the line [tex]y=4[/tex], the slope must be equals to [tex]0[/tex].
So, [tex]y=0[/tex] is the only option in which the slope is equals to zero and so, it is parallel to the line [tex]y=4[/tex].
