Solve using systems by substitution whats is y=x+8 and x+y=2
Answer:
Step-by-step explanation:
y = x + 8
x + y = 2
using substitution, since y is equal to x + 8 we substitute it for the y in x + y = 2
so we get: x + (x+8) =2
then we simplify, getting 2x + 8 = 2
We make the x on its own on one side of the equation by subtracting 8 on both sides.
2x = -6
divide
x = -3
y = 5
(if x = -3, y = 5 because -3 + 8 =5)
test answer
5 = -3 + 8 works and -3 + 5 = 2 works as well

Does scientific notation have to be greater than 1?
The mantissa of scientific notation is between 1 and 10 in absolute value, or 1 ≤ |a| < 10. It can be 1, hence, it does not have to be greater than 1.
A scientific notation has the form:
a x 10ᵇ
Where b is an integer and is called exponent.
a is a real number between 1 and 10 (in absolute value), it includes 1 but not 10, or we can write a should satisfy 1 ≤ |a| < 10.
Usually, a is called mantissa.
Example:
2567 can be written in scientific notation as:
2567 = 2.567 x 10³
0.0045 can be written in scientific notation as:
0.0045 = 4.5 x 10⁻³
250 x 10² can be written in scientific notation as:
250 x 10² = 2.5 x 10⁴
-0.032 can be written in scientific notation as:
-0.032 = -3.2 x 10⁻²

Help with geometry similar triangles. ABC ~ ADE. Solve for x.
Answer:
x=18
Step-by-step explanation:
We know that triangle ABC is similar to triangle ADE, so therefore the proportions of their corresponding sides must be congruent.
We know that all of AD is 15 and BD is 5, which leaves AB to be equal to 10.
Next, we set up the following proportion: 10/12 = 15/x because they are corresponding sides of similar triangles divided by eachother.
Cross multiply and you will get 10x = 12x15 (180)
next, divide both sides by 10 to isolate x
x = 18

The situation regarding the experimental probability is described as follows:
The probability that she makes a shot is of 62.5% = 5/8. Use whole numbers from 1 to 8, with 1-5 representing shots that she makes, and 6-8 representing the shots that she misses. For each trial, generate 10 random numbers. Count the number of trials in which the numbers 1 - 5 appears 3 or more times. Divide the number of trials in which she made at least 3 shots by the total number of trials.
How to obtain a probability?A probability is calculated as the division of the number of desired outcomes by the number of total outcomes.
The theoretical probability of making a shot in this problem is given as follows:
62.5%.
The equivalent fraction is given as follows:
5/8.
Hence, to obtain the experimental probability, we need to design an experiment for which there are eight possibilites, with five of them composing a success and three of them composing a failure.

Paragraph prove statement
The paragraph proof is a proof written in the form of a paragraph. In other words, it is a logical argument written as a paragraph, giving evidence and details to arrive at a conclusion.
What is Paragraph prove statement?Paragraph proofs are comprehensive paragraphs that explain the process of each proof. Like two-column proofs, they have multiple steps and justifications. But instead of columns, the given information is formatted like a word problem — written out in long-hand format.
Since vertical angles are congruent, it is known that angle DCB is congruent to angle ACE. It can now be concluded that triangle DCB is congruent to triangle ACE according to the Side-Angle-Side (SAS) theorem.
There are two different types of proofs: informal and formal. Formal proof is often introduced using a two-column format, as favored by many geometry teachers.

For what value of A is x 5 a factor of x² 3x² ax 10?
The value of A when x - 5 is a factor of x³ - 3x² + ax - 10 is -8.
A polynomial factor is a polynomial that divides another polynomial exactly, with no remainder.
For example, if we have a polynomial P(x) = x³ - 3x² + ax - 10, and we have a polynomial factor F(x) = x - 5, we can say that P(x) is divisible by F(x) with no remainder.
In general, a polynomial of degree n has n roots (or zeroes) and the factorization of polynomial can be expressed as a product of its roots and its corresponding multiplicity.
To find the value of A, set x = 5 in the equation x³ - 3x² + ax - 10 and solve for A that will make the equation equal to zero..
So when x = 5, we have:
x³ - 3x² + ax - 10 = 0
(5)³ - 3(5)² + a(5) - 10 = 0
125 - 75 + 5a - 10 = 0
5a = -40
a = -8
Hence, if x - 5 is a factor of x³ - 3x² + ax - 10, then A is equal to -8.

equation can be used to find the amount, in dollars, x, of check 353?
A. 1,225.70 + x = 1,460.89
B. 1,225.70 +25.79 + x = 1,460.89
c. 1,460.89 +* 1,536.71
D. 1,460.89 +25.79+ x = 1,536.71
The correct equation to find the amount, in dollars, x, of check 353 is:
D. 1,460.89 +25.79+ x = 1,536.71
How to solve the equationThis equation shows that the sum of check 354, check 353, and the known total of 1,460.89 is equal to the corrected total of 1,536.71. So by solving for x, you can find the amount of check 353.
To solve for x, you would subtract 25.79 and 1,460.89 from both sides of the equation:
x = 1,536.71 - 1,460.89 - 25.79
x = 50.03
So the amount of check 353 is $50.03
It is important to notice that option A and B doesn't include the missing check 354, and option C doesn't add the missing check 354 and the corrected total, so option D is the right one.

Choose the statement that describes a relationship that has a negative slope. A Stan makes $2 for every customer on his newspaper route. B Lisa's parents give her $10 each week for her allowance. C Greg pays $25 each time he goes rock climbing. D The booster club makes $3 profit for each t-shirt they sell.
The statement that describes a relationship that has a negative slope: "Greg pays $25 each time he goes rock climbing".
What is negative slope?A negative slope indicates that two variables are adversely connected; that is, when x rises, y falls, and when x falls, y rises. A negative slope on a line graph signifies that the line falls as it travels from left to right. For example, when the number of individuals that quit smoking (x) grows, the number of persons developing lung cancer (y) drops. This relationship's graph has a negative slope. Positive slopes are predicated on the fact that when x grows, so does y, hence the change in y/change in x is positive. Negative slopes are based on the fact that when x grows, y decreases, resulting in a negative change in y/positive change in x, yielding a negative response.

Step-by-step explanation:
the tangents are negative in the quadrant II or IV
and sines are negative in the quadrant III or IV
so i think that this angle is in quadrant IV to satisfy for the of the both requirements.
but angle 0 seems to try and mean something other than 0 degrees or 0 radians. so It probably just means theta, which is a 0 probably with a line through it
IF tan(theta) = -8/7 = opposite side/adjacent side, then sin(theta) = -8/(sqr(64+49) = -8/sqr113 = about -0.7526

The polynomial 3x³ 2x² +3 can be written as 3x³ + 2x² + 3. In order to get the polynomial 3x² + 4, we need to add a polynomial which is equal to -3x³ + 5x² + 1.
Therefore, the correct answer is (3) - 3x3 + 5x2 +1.
We can confirm this by performing the following calculation:
3x³ + 2x² + 3 + (-3x³ + 5x² + 1) = 3x² + 4
3x³ + (-3x³) = 0
2x² + 5x² = 7x²
3 + 1 = 4
Therefore, 0 + 7x² + 4 = 3x² + 4, which confirms that the correct answer is 3x3 + 5x2 +1.
3x3 + 5x2 +1 is the polynomial should be added in 3x³ 2x² +3 to get the polynomial 3x² +4.
