Create a table for the equation with a y-intercept of 15 and a slope of -5. What is the output when x is -10?
x y
-2
-1
0
1
2
-6 ?
Answer:
The output is 65 when x is -10.
Step-by-step explanation:
y=mx+b is the easiest form to understand visually what the slope and intercept is.
m is the slope and b is the y-intercept. Replace both of these variables respectively with their appropriate values. In this case, the slope (m) is -5 and y-intercept is 15.
Equation looks like this: y=-5x+15
What is the output when x is -10? Replace x with 10, and your output is the y value.
[tex]y=-5(-10)+15\\y=50+15\\y=65[/tex]

by what percent will a fraction change if its numerator is decreased by 75% and it denominator is decreased by 50%?
Answer:
33%
Step-by-step explanation:
Answer:
50%
Step by Step explanation
first the numerator is decreased by 75% so its 0.25. the denominator is decreased by 50% so its 0.5. Then, we will divide 0.25 and 0.5 which equals 0.5. to find %, do 0.5*100 which equals 50%

Consider a system with sampling rate 52,500 samples per second.
(a) Determinethe maximum frequency of the pre-sampled signal if the system utilizes 18% oversampling.
(b) Determine the percentage oversampling if the maximum frequency from part (a) isincreased by 10%.
Answer:
The answer is "[tex]22,246 \ H_z \ \ and \ \ 7.3\%[/tex]"
Step-by-step explanation:
The sampling rate: [tex](f_s) = 52,500 \ \frac{samples}{sec}[/tex]
In point a:
The sample signal frequency = f
They recognize that the id [tex]\geq[/tex] 2f sampling frequency could be returned to its original signal unless the aliase effect is detected elsewhere, Yet under percentage =18%
[tex]\ sampling \ rate = 2 \times 1.18 \times f[/tex]
[tex]\to f = \frac{52,500}{2 \times 1.18}\\\\[/tex]
[tex]= 22,246 \ h_z[/tex]
In point b:
Maximum 22,242 frequency is increased by [tex]10 \ \%[/tex]
[tex]f_a =22,246 \times 1.1[/tex]
[tex]= 24,470.6\\\\=24,471[/tex]
[tex]\ sampling \ rate= x \times 2 \times 24,2471 \\[/tex]
[tex]x= \frac{52,500}{48,942} \\\\x= 1.073\\\\[/tex]
over sampling percentage [tex]= 7.3 \ \%[/tex]
Marion and Stefan played a game called "Go." Marion won five times the difference between the number of games Stefan won and the number four. If Marion won fifteen games, then how many games did Stefan win?
Answer:
1 game
15/5=3
4-3=1
Hope it helps
please follow me
Using a system of equations, it is found that Stefan won 7 games.
In our system, we have that:
x is the number of games Marion won.y is the number of games Stefan won.Marion won five times the difference between the number of games Stefan won and the number four, hence:
[tex]x = 5(y - 4)[/tex]
Marion won 15 games, hence [tex]x = 15[/tex], and:
[tex]15 = 5(y - 4)[/tex]
[tex]y - 4 = 3[/tex]
[tex]y = 7[/tex]
Stefan won 7 games.

Select the correct answer. What is the solution to the equation |5 − x| = 13? A. x = -8 or x = 18 B. x = -18 or x = 8 C. x = 8 D. x = -18
Answer: A) X = -8 or X = 18
Step-by-step explanation:
Since we're dealing with absolute value, there are going to be two different solutions to this equation.
5 - x = 13
-x = 8
x = -8
OR
5 -x = -13 ( the negative is from the absolute value)
-x = - 18
x= 18
The value of x is either -8 or 18 (option A)
What is an equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
Given is an equation, |5-x| = 13
Solving the equation,
|5-x| = 13
When we will remove the modulus, we will get two conditions,
5-x = 13 or 5-x = -13
Solving both one by one,
5-x = 13
x = -8
And,
5-x = -13
x = 18
Hence, the value of x is either -8 or 18

How many solutions are there to the equation below?
4x-9(x+ 1) = 20- 5x
OA. 1
O B. 0
OC. Infinitely many
Answer:
no solution
Step-by-step explanation:
heres why:
Let's solve your equation step-by-step.
4x−9(x+1)=20−5x
Step 1: Simplify both sides of the equation.
4x−9(x+1)=20−5x
4x+(−9)(x)+(−9)(1)=20+−5x(Distribute)
4x+−9x+−9=20+−5x
(4x+−9x)+(−9)=−5x+20(Combine Like Terms)
−5x+−9=−5x+20
−5x−9=−5x+20
Step 2: Add 5x to both sides.
−5x−9+5x=−5x+20+5x
−9=20
Step 3: Add 9 to both sides.
−9+9=20+9
0=29
so there are no solution

Imagine that you are of traditional college age and you apply for a direct marketing position, and in the interview for the position, you are told that you look to young for the position. You have been discriminated against. This is a violation of:___________
Answer:
when grounds intersect.
Step-by-step explanation:
Analyzing the information related to the question above, it is possible to identify that the candidate for the direct marketing position suffered a violation when the grounds intersect.
It is correct to state this on the basis that the candidate was of traditional university age, but in the interview it is said that young people are sought for the position.
This type of discrimination can occur when the individual is discriminated against due to overlapping of several reasons, in the case of the candidate he was seen as a person older than he appeared to be, even though he was a requested age.
