The solution of a linear equation with rational coefficients is a rational number. A. Always B. Never C. Sometimes
9514 1404 393
Answer:
A. Always
Step-by-step explanation:
A linear equation with rational coefficients can be written in the form ...
ax +b = 0
The solution for the variable x is ...
x = -b/a
The problem statement tells us that 'a' and 'b' are rational numbers. Assuming there is a solution (a≠0), that solution is the ratio of rational numbers, hence must always be rational.
Use the Rational Zero Theorem to list all possible rational zeros for the given function.
f(x) = x^3 + 10x^2 + 15x – 14
9514 1404 393
Answer:
±1, ±2, ±7, ±14
Step-by-step explanation:
The rational root theorem tells you any rational roots will be of the form ...
±(divisor of the constant)/(divisor of the leading coefficient)
For this function, that means rational roots will be of the form ...
±(divisor of 14)
Those divisors are 1, 2, 7, 14. Possible rational roots are ...
±1, ±2, ±7, ±14
_____
Additional comment
The graph shows this function has 3 irrational roots.

Answer:
Solution: (3,5)
Step-by-step explanation:
y = x + 2 and
y = - x + 8
y = y
x + 2 = -x + 8
x + x = 8 - 2
2x = 6
x = 6/2
x = 3
Substitute x for 3 in one of the equations to find y.
y = 3 + 2
y = 5
The number of workers w(t) for each Medicare beneficiary (each person receiving Medicare benefits) is approximated by the function w(t)=-0.05 t+4,$ where t is the number of years after 2000. Use an inequality to determine those years for which there will be less than 2 workers for each Medicare beneficiary.
Step-by-step explanation:
In 2020, 62.6 million people were enrolled in the Medicare program, which equates to 18.4 percent of all people in the United States. Around 54 million of them were beneficiaries for reasons of age, while the rest were beneficiaries due to various disabilities.
Gas right now is $ 2.99 per gallon !! AH !!! How much will it clllost to fill the tank of my car that holds 9 gallons ?
Show all work...
Answer:
$26.91

That equals $26.91.
Answer:
$26.91
Step-by-step explanation:
Since 1 gallon costs $2.99, multiply 2.99 by 9.
2.99 x 9
= $26.91

You have 7 times as many nickels
as pennies. You have 16 nickels
and pennies altogether. How
much money do you have in all?
The total money you have is $40.14.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
There are 7 times as many nickels as pennies
Let there are n nickles and p pennies.
⇒ p = 7n
Now, there are 16 nickels and pennies altogether
⇒ p + n = 16
Put p = 7n we get,
⇒ 7n + n = 16
⇒ 8n = 16
⇒ n = 16/8
⇒ n = 2
Therefore, p = 7*2
⇒ p = 14
Thus there 14 pennies and 2 nickels.
Now, since 1 penny = 0.01 dollars
and 1 nickel = 20 dollars
⇒ 14 pennies = 14*0.01 dollars = 0.14 dollar
and, 2 nickel = 2*20 dollars = 40 dollars
So, Total money = $40 + $0.14
⇒ Total money = $40.14
Thus, the total money you have is $40.14.

Suppose the value of x varies from x = a to x = b . There are at least two ways of thinking about what percent x changed by. We'll explore two of them here. For each of the following questions, write an expression in terms of a and b to answer the question. Method 1 b is how many times as large as a ? times as large Therefore, b is what percent of a ? % Hence, if x varies from x = a to x = b , x changes by what percent?
The change in the value of x, as a percentage, is given by:
[tex]\frac{b - a}{a} \times 100\%[/tex]
The percentage change is given by the change multiplied by 100% and divided by the initial value.
In this question, x varies from [tex]x = a[/tex] to [tex]x = b[/tex], which means that the initial value is a, and the change is b - a. Then, the percentage chance in the value of x is given by:
[tex]\frac{b - a}{a} \times 100\%[/tex]
A similar problem is given at https://brainly.com/question/24729807
Answer:
Step-by-step explanation:
i. b is how many times as large as a?
b/a
ii. Therefore, b is what percent of a?
b/a*100
iii. Hence, if x varies from x=a to x = b, x changes by what percent?

Answer:
56
Step-by-step explanation:
1. We can use the exterior angle theorem to find the value of y. The exterior angle theorem states that the exterior angle of a triangle is equal to the sum of the two remote sides. This means that (y - 25) + (y + 12) = y + 43
2. (Solving)
Step 1: Simplify both sides of the equation.
[tex]y + 43 = y - 25 + y + 12[/tex] [tex]y + 43 = (y+y)+(-25+12)[/tex] [tex]y + 43 = 2y -13[/tex]Step 2: Subtract 2y from both sides.
[tex]y + 43 - 2y = 2y - 13 - 2y[/tex] [tex]-y + 43 = 13[/tex]Step 3: Subtract 43 from both sides.
[tex]-y + 43 - 43 = 13 - 43[/tex] [tex]-y = -56[/tex]Step 4: Divide both sides by -1.
[tex]\frac{-y}{-1} = \frac{-56}{-1}[/tex] [tex]y = 56[/tex]Step 5: Check if solution is correct.
[tex](56) + 43 = (56) - 25 + (56) + 12[/tex] [tex]109 = 31 + 56 + 12[/tex] [tex]99 = 87 +12[/tex] [tex]99 = 99[/tex]Therefore, y = 56.

Which equation represents a line with a slope of -8 and
a y-intercept of 4?
A y = -8x+4
B y = -4x+8
C y = - 8x-4
D y = 8x+4
Answer: A. y = -8x + 4 because the slope goes in front with the x (-8x) and the y intercept is after the slope (4)
Describe how to graph a line using the slope amen y intercept
Answer:
The Slope-Intercept form of the equation of a line is: y=mx + b
where m=slope (often called 'rise over run')
b = y-intercept (the point on the y-axis when x=0)

c: sin0=12/13
d: cos0=12/13
Answer:
a:tan0= 12/5
c: sin0=12/13
Step-by-step explanation:
cosec t(heta) = 13/12
1/sin t = 13/12
sin t = 12/13
cos t = √ (1 - (12/13)² ) = √ ( 1 - 144/169 ) = √25/169
cos t = 5/13
tan t = sin t/ cos t = (12/13) / (5/13) = 12/5
sec t = 1 / cos t = 13/5
Answer: A ) and C ) are correct:
tan theta = 12/5 and sin theta = 12/13
Consider the following vectors.

Find the scalar triple product u · (v ⨯ w).

Are the given vectors coplanar?
Yes, they are coplanar.
No, they are not coplanar.
Need Help? Read It
The scalar triple product is 0.
If v = 4i - j and w = 6i + 7j - 4k, then their cross product is
v × w = (4i - j) × (6i + 7j - 4k)
v × w = 24 (i × i) + 28 (i × j) - 16 (i × k) - 6 (j × i) - 7 (j × j) + 4 (j × k)
v × w = 28k - 16 (-j) - 6 (-k) + 4i
v × w = 4i + 16j + 34k
and
u • (v × w) = (i + 4j - 2k) • (4i + 16j + 34k)
u • (v × w) = 4 + 64 - 68
u • (v × w) = 0
Yes, they are coplanar.
The vectors v and w together span a plane. v × w is a vector that is perpendicular to this plane. Since the dot product of u with this vector is 0, this means u is perpendicular to v × w, which in turn means that u is in the same plane as v and w.
