is y=10/x linear or not
Answer:
Yes it goes in a straight line
Step-by-step explanation:
A graph of a function y = f(x) is symmetric with respect to the origin if replacing x by -x and y by -y yields the same function. For y = 10x, if we replace x by -x and y by -y, we get -y = -10x, which simplifies to y = 10x. Thus, the graph of y = 10x is symmetric with respect to the origin.
Linear functions are odd degree functions. These type of functions do not have any symmetry with respect to the either axis.
However, the function y=mx+b
where m = ±1
b = 0
does have symmetry with respect to the origin.

Answer:9.7%/year
R = 9.7%/year
Formula:r = I / Pt
Step-by-step explanation:Mark me as Brainlieist
Calculation:
Solving our equation
r = 87.3 / (1800 × 0.5) = 0.097
r = 0.097
converting r decimal to a percentage
R = 0.097 × 100 = 9.7%/year
The interest rate required to
accumulate simple interest of $87.30
from a principal of $1,800.00
over 0.5 years, is 9.7% per year.

Answer:
x=9/2
Step-by-step explanation:
Multiply the numbers
8 ( − 1 ⋅ 3/ 4 )= − 3 + 3 3
8 ( − 3 4) = − 3 + 3 3
Distribute
8 ( − 3 4 ) = − 3 + 3 3
8x-6=30
Add six to both sides
8x-6+6=30+6
Simplify
8x=36
Divide both sides of the equation by the same term
8x=36
8x/8 = 36/8
Then you cancel the terms that are in both the numerator and the denominator and divide the numbers
x=9/2
Answer:
x=4.5

Step-by-step explanation:
To find 10% of a number all you need to do is move the decimal to the left once. Explain why this is true
When dividing by 10, 100, 1000 and so on, move the decimal point to the left as many places as there are 0s. So when dividing by 10, move the decimal point one place, by 100 two places, by 1000 three places and so on. If there is no decimal point in the original number, then imagine it at the end of the number.
(a). Consider the parabolic function f(x) = ax² +bx+c, where a ±0, b and care constants. For what values of a, band c is f
(i) concave up?
(ii) concave down?
[Verify your answer by MATHEMATICA and attach the printout of the commands and output]
Information about concavity is contained in the second derivative of a function. Given f(x) = ax² + bx + c, we have
f'(x) = 2ax + b
and
f''(x) = 2a
Concavity changes at a function's inflection points, which can occur wherever the second derivative is zero or undefined. In this case, since a ≠ 0, the function's concavity is uniform over its entire domain.
(i) f is concave up when f'' > 0, which occurs when a > 0.
(ii) f is concave down when f'' < 0, and this is the case if a < 0.
In Mathematica, define f by entering
f[x_] := a*x^2 + b*x + c
Then solve for intervals over which the second derivative is positive or negative, respectively, using
Reduce[f''[x] > 0, x]
Reduce[f''[x] < 0, x]

The options are given as follows
A. (0,2)
B. (-3,5)
C.(-1,1)
D. (4,0)
Whichever option of ordered pair will satisfy the given inequality will be the solution set for the given in-equation.
By trying all the options as following
A. (0,2)
[tex]\rm 8 (0) +16\times (2) >32\\32> 32 \; is\; false[/tex]
B (-3,5)
[tex]\rm 8\times (-3) +16 \times 5 > 32\\-24 + 80 > 32\\56 > 32 \; is \; true[/tex]
C.(-1,1)
[tex]\rm 8 \times (-1) + 16 \times (1) > 32\\-8 + 16 > 32 \\8 > 32 \; is \; false[/tex]
D. (4,0)
[tex]\rm 8 \times 4 + 16 \times 0 > 32 \\32 > 32 \; is \; false[/tex]

isabel prepaid debit card with $20 on it. For her Arst purchase with the card, she bought some bulk ribbon at a
rd. If after that purchase there was $15.52 left on the card, hew many vards of ribbon did Isabel buy?Isabel got a prepaid debit card with $20 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 14
cents per yard. If after that purchase there was $15.52 left on the card, how many yards of ribbon did Isabel buy?
Answer:
32 yards
Step-by-step explanation:
Subtract 15.52 by 20 to find out how much she spent.
She spent $4.48.
Divide 0.14 to find out how many yards of ribbon $4.48 can buy.
She bought 32 yards.
Division is one of the four fundamental arithmetic operations. The number of yards of ribbon is 33.93 yards.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Isabel prepaid a debit card with $20 on it. Also, after that purchase, there was $15.52 left on the card. Therefore, the cost of the total ribbon can be written as,
Cost of total Ribbon = Total Balance in debit card - Balance after purchase
= $20 - $15.25
= $4.75
It is further mentioned that the price of the ribbon was 14 cents per yard. Therefore, we can write,
Yards of ribbon = Cost of total Ribbon / Cost of a yard of ribbon
= $4.75 / $0.14 per yards
= 33.93 yards
Hence, the number of yards of ribbon is 33.93 yards.

Write an equation for the line that is parallel to the given line and that passes through the given point.
y = 2^x + 7; (3, 11)
A. y = 2^x + 5
B. y = 1/2x + 5
C. y = -1/2x – 5
D. y = 2^x - 19
Answer:
A. y = 2^x + 5
Step-by-step explanation:
The equation is not linear, so a constant slope does not exist.
Not Linear PARALLEL
...................................................................................................................................................
The equation is not linear, so a constant slope does not exist.
Not Linear PERPENDICULAR
...............................................................................................................................................
First, remember that if two lines are parallel, they have the same slope. The problem already gave us a point on the line and we now have the power to find the slope. Since we have the slope and a point on the line, we are going to find the equation of the line through the point-slope formula, which is:
is a point on the line
is the slope of the line
The equation given to us has a slope of 2, as we can see because the line is in slope-intercept form. Also, we are given the point (3, 11), which we are told is on the line. Since we are already given all of the information for the point-slope formula, we can simply substitute it in and solve for the equation.
Set up
Use the Distributive Property on both sides
Add 11 to both sides and simplify
The equation of our line is y = 2x + 5.
...............................................................................................................................................
Slope-intercept form:
y = mx + b "m" is the slope, "b" is the y-intercept (the y value when x = 0)
For lines to be parallel, they have to have the SAME slope.
The given line's slope is 2, so the parallel line's slope is also 2.
y = 2x + b
To find "b", plug in the point (3,11) into the equation.
y = 2x + b
11 = 2(3) + b Multiply 2 and 3
11 = 6 + b Subtract 6 on both sides
5 = b
y = 2x + 5
