Answer:
-9<x<31
Step-by-step explanation:
|11 – xl < 20
There are two solutions, one positive and one negative, remember to flip the inequality for the negative
11-x < 20 and 11 -x > -20
Subtract 11 from each side
11-x-11 <20-11 and 11-x-11 >-20-11
-x <9 and -x > -31
Multiply each side by -1, remembering to flip the inequality
x>-9 and x< 31
-9<x<31

Why 1975 can't be the sum of two squares. Or prove that the equality x ^ 2 + y ^ 2 = 1975 has no solutions in integers
Answers
Answer:
Step-by-step explanation:
If a number can be expressed by sum of two square, only if the number can be represented by 4k + 1 form
1975 = 4*493 + 3
So, 1975 can't be a sum of two squares
Show that an exponential model fits the data. Then write a recrusive rule that models the data.

Answers
Answer:
x=14.2
Step-by-step explanation:
AC = BD
The diagonals of a rectangle are equal
7x-9 = 2x+62
Subtract 2x from each side
7x-9-2x = 2x+62-2x
5x-9 = 62
Add 9 to each side
5x-9+9 = 62+9
5x= 71
Divide by 5
5x/5 = 71/5
x=14.2

what is the answer for 7 to the negitive second power.
Answers
Answer:
the negative just tell you you put a one over the number. Once that's done, the power will be positive, and you can square like normal
Are you asking about [tex]7^{-2}[/tex] ?
If so:
A negative in the exponent tells us that we must take the reciprocal of the number, in this case, 7, and then use the exponent like normal:
[tex]7^{-2}[/tex] =
[tex](\frac{1}{7})^{2}[/tex] =
[tex]\frac{1}{49}[/tex],
So our answer is 1/49.

Find the equation of the line that
is parallel to y = 4x + 1 and
contains the point (1, 1).
y = [? ]X + [ ]
Answers
Answer:
y = 4x - 3
Step-by-step explanation:
A parallel line will have the same slope so the slope will remain 4. To fine the new y-intercept, we can substitite the point we are given.
1 = 4(1) + b
1 = 4 + b
-3 = b
Now, we can create the new equation with the information we found.
y = 4x - 3
Best of Luck!
Answer: y = 4x - 3

Find the probability that a randomly selected point within the circle falls in the white area. Please, and thank you.
Answers
Answer:
About 68.2%.
Step-by-step explanation:
We want to find the probability that a randomly selected point lands in the white area.
To do so, we can find the probability that the point does not land in the white area (i.e. the red area) and then subtract it from 100%.
The circle has a radius of 4 cm. Note that the base of the triangle is the diamater, so the base measures 8 cm. The height of the triangle is the radius, so it measures 4 cm. Thus, the area of the triangle is:
[tex]\displaystyle \begin{aligned} A &= \frac{1}{2}bh \\ &= \frac{1}{2}(8)(4) \\ &= 16\text{ cm}^2\end{aligned}[/tex]
Likewise, the area of the entire circle will be:
[tex]\displaystyle \begin{aligned} A &= \pi r^2 \\ &= \pi(4)^2 \\ &=16\pi \text{ cm}^2\end{aligned}[/tex]
Then the probability that a randomly seleted point lands in the red area is:
[tex]\displaystyle P\left(\text{Red}\right) = \frac{\text{Red}}{\text{Total}} =\frac{16}{16\pi} = \frac{1}{\pi}[/tex]
The probability that the point lands in the red area or the non-red area (i.e. white area) must total 100%. In other words:
[tex]\displaystyle P\left(\text{Red}\right) + P\left(\text{White}\right) = 1[/tex]
Thus:
[tex]\displaystyle P\left(\text{White}\right) = 1 - P\left(\text{Red}\right)[/tex]
Substitute:
[tex]\displaystyle P\left(\text{White}\right) = 1 - \left(\frac{1}{\pi}\right)[/tex]
Use a calculator. Hence:
[tex]\displaystyle P\left(\text{White}\right) \approx 0.6817 = 68.2\%[/tex]
The probability that a randomly selected point lands in the white area is about 68.2%.

You do the opposite function to find your answer
Answer:
1. t = 21
2. s = 2
3. c = 6
4. v = 45
Step-by-step explanation:
1. t - 19 = 2
*Add 19 to both sides.
t = 21
2. 1 + s = 3
*Subtract 1 from both sides.
s = 2
3. 24 = 4c
*Divide each side by 4.
6 = c
4. v/5 = 9
*Multiply each side by 5.
v = 45

Answer:
a=3
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2+4^2 = 5^2
a^2 +16 = 25
a^2 =25-16
a^2 = 9
Taking the square root of each side
sqrt(a^2) = sqrt(9)
a =3
