Answer:
a=−b−2x+5/x
Step-by-step explanation:
Step 1: Flip the equation.
ax+b+4=−2x+9
Step 2: Add -b to both sides.
ax+b+4+−b=−2x+9+−b
ax+4=−b−2x+9
Step 3: Add -4 to both sides.
ax+4+−4=−b−2x+9+−4
ax=−b−2x+5
Step 4: Divide both sides by x.
ax/x=−b−2x+5/x
a=−b−2x+5/x

Step-by-step explanation:
what is the distance between (-8,5) and (-1,5)
Answer:
7 units
Step-by-step explanation:
(see attached for reference)
given two points (x₁, y₁) and (x₂, y₂), the formula for distance between two points is given as
Distance, D = √( (x₂-x₁)² + (y₂-y₁)² )
in our case, we are given
(x₁, y₁) = (-8,5)
(x₂, y₂) = (-1,5)
simply substitute the values into the equation above:
D = √( (x₂-x₁)² + (y₂-y₁)² )
= √{ [ (-1)-(-8) ]² + (5-5)² }
= √{ [ (-1 + 8) ]² + (0)² }
= √[ (7) ² ]
= 7 units (answer)

The probability of a randomly selected adult in one country being infected with a certain virus is 0.004. In tests for the virus, blood samples from 15 people are combined. What is the probability that the combined sample tests positive for the virus? Is it unlikely for such a combined sample to test positive? Note that the combined sample tests positive if at least one person has the virus.
Answer:
The probability is [tex]P(R) = 0.0583 [/tex]
Step-by-step explanation:
From the question we are told that
The probability that selected adults are affected by virus is p = 0.004
The probability that adults are not affected by virus is [tex]q= 1- p = 1-0.004 = 0.996[/tex]
The sample size is n = 15
Generally from the question we are told that
The probability that the combined sample tests positive is equal to the probability that at least one person test positive for the virus
So
The probability that the combined sample tests positive for the virus is equal to
1- the probability that non of the adults selected tested positive for the virus
Generally the probability that non of the adults selected tested positive for the virus is
[tex]P(k) = q^n[/tex]
=> [tex]P(k) = q^{15}[/tex]
=> [tex]P(k) = 0.996^{15}[/tex]
=> [tex]P(k) = 0.9417 [/tex]
The probability that the combined sample tests positive for the virus is mathematically represented as
[tex]P(R) = 1 - P(k)[/tex]
=> [tex]P(R) = 1 - 0.9417 [/tex]
=> [tex]P(R) = 0.0583 [/tex]

Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian's first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.
Answer:
21.9 feet
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.
Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?
Given parameters
Altimeter of vivian at its lowest point = -9.6 feet
Altimeter of vivian at the top of the wheel = 12.3feet
Note that the sea level is at 0 feet.
change in Vivian's elevation from the bottom of the Ferris wheel to the top is expressed as:
= (12.3-0)+(0-(-9.6))
= 12.3+(0+9.6)
= 12.3+9.6
= 21.9 feet
From the gotten value, it can be seen that the change in Vivian's elevation from the bottom of the Ferris wheel to the top is a positive value.
The value is positive because vivian keeps moving to the top of the wheel (above the sea level). The values above the sea level is always positive.
Answer:Hide Sample Answer
The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.
Step-by-step explanation:Hide Sample Answer
The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.

Step-by-step explanation:
The given equation is :
[tex]\dfrac{c}{2}-5=7[/tex]
Adding both sides by 5 both sides,
[tex]\dfrac{c}{2}-5+5=7+5\\\\\dfrac{c}{2}=12[/tex]
Cross multiplying both sides,
[tex]c=2\times 12[/tex]
c = 24
So, the value of c is 24.
We want to factor the following expression:
16x4 – (y - 1)
We can factor the expression as (U+V)(U - V) where U and V are either constant integers or single-variable expressions.
What are U and V?
Answer:
Answer: U = 4x^2 and V=y-1
factored : (4x^2+y-1)(4x^2-y+1
Step-by-step explanation:
The value of U and V are 4x² and (y-1) respectively and the factor of the expression is (4x² + (y-1)) and (4x² + (y+1)) option (C) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.

We want to factor in the following expression:
16x⁴-(y-1)²
We can factor the expression as (U+V)(U-V) where U and V are either constant integers or single-variable expressions.
1) What are U and V?
2)Factor the expression.
We have an expression:
= 16x⁴-(y-1)²
or
= (4x²)²-(y-1)²
Using the identity:
a² - b² = (a + b)(a- b)
(4x²)²-(y-1)² = (4x² + (y-1))(4x² + (y+1))
The value of U = 4x²
V = (y-1)
The factor of the expression is:
(4x² + (y-1)) and (4x² + (y+1))
Thus, the value of U and V are 4x² and (y-1) respectively and the factor of the expression is (4x² + (y-1)) and (4x² + (y+1))

a bricklayer stacks bricks in 2 rows with 10 bricks each in each row on top of each row there is a stack of 6 bricks how many bricks are there in total
Let me see.
Row 1 = 10 bricks
Row 2 = 10 bricks
On top of each row there are 6 bricks.
Two rows times 6 bricks per row is 12 bricks.
Total = 20 + 12 or 32 bricks.
Consider the equation −3+(−9.25)+m=0 .
Let's solve your equation step-by-step.
−3−9.25+m=0
Step 1: Simplify both sides of the equation.
−3−9.25+m=0
−3+−9.25+m=0
(m)+(−3+−9.25)=0(Combine Like Terms)
m+−12.25=0
m−12.25=0
Step 2: Add 12.25 to both sides.
m−12.25+12.25=0+12.25
m=12.25
Answer:
m=12.25
1. Yearly membership with the online music club costs $48. Members pay $0.99 per song to download music. Nonmembers may download songs for $1.29 each.
Answer:
160 musics
Step-by-step explanation:
let the total amount/charges be y
let the number of musics be x
For members total
y=48+0.99x-------1
For non-members total
y=1.29x-------------2
we are expected to solve for the number of music where members and non members get to pay the same amount
equating 1 and 2 we have
48+0.99x=1.29x
48=1.29x-0.99x
48= 0.3x
x=48/0.3
x=160 musics
