Answer:
Alexandra's weekly expenses is $234
Step-by-step explanation:
Selling price of 1 kg cumin = $7.20
She sells amount of cumin = 20 kg
Selling price of 90 kg cumin = 90 \times 7.20
Selling price of 90 kg cumin =648
We are given that his weekly profit is $414
We are supposed to find his weekly expense
So, Expense = SP - Profit
Expense = 648-414
Expense=$234
Hence Alexandra's weekly expenses is $234
The points A,B and C lie on a straight line
The coordinates of A are (9,0)
The coordinates of B are (7,4)
The coordinates of C are (1,q)
Work out the value of q
The value of q is 16.
What are Collinear Points?Collinear points are the points which are formed on a straight line, whether they are close or far away.
If three or more points are collinear, then they form on the same line.
The slope of each pair of points will be same.
Here if A, B and C are collinear,
Slope of AB = Slope of BC
(4 - 0) / (7 - 9) = (q - 4) / (1 - 7)
-2 = (q - 4) / -6
q - 4 = 12
q = 16
Hence the value of q is 16.

Let f(x)=x-5 and g(x)=x^2-7x+8 find f(x) × g(x)
Answer:
x³ - 12x² + 43x - 40
Step-by-step explanation:
f(x) × g(x)
= (x - 5)(x² - 7x + 8)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x² - 7x + 8) - 5(x² - 7x + 8) ← distribute both parenthesis
= x³ - 7x² + 8x - 5x² + 35x - 40 ← collect like terms
= x³ - 12x² + 43x - 40

Use distributive property to factor method 1. Use distributive property to expand method 2.
Step-by-step explanation:
I guess method 1 means to deal with whole factors.
x + 5 = (x - 2)(x + 5)
for (x + 5) <> 0 we can divide both sides by this factor :
1 = x - 2
x = 3
for the second solution we deal with
x + 5 = 0
x = -5
so, for x = -5 and x = 3 both functions deliver the same output, and these are the intersection points.
method 2 : we multiply the expression out and solve it then
x + 5 = (x - 2)(x + 5)
x + 5 = x² + 5x - 2x - 10 = x² + 3x - 10
0 = x² + 2x - 15
the general solution to such a square equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 2
c = -15
x = (-2 ± sqrt(2² - 4×1×-15))/(2×1) =
= (-2 ± sqrt(4 + 60))/2 = (-2 ± sqrt(64))/2 = (-2 ± 8)/2 =
= -1 ± 4
x1 = -1 + 4 = 3
x2 = -1 - 4 = -5
and you get the 2 solutions again. as expected, they are the same as with method 1, of course.

Let f(x) = -2x +49 and g(x) = -4x + 3. Find
(fºg)(-5).
Answer:
3 i think
Step-by-step explanation:
so we substitute -5 to g(x)
g(x) = -4(-5) + 3
= 20 + 3
= 23
now we substitute it to f(x)
f(x) = -2x + 49
= -2(23) + 49
= -46 + 49
= 3
Answer:
3
Step-by-step explanation:
f(x) = -2x + 49
g(x) = -4x + 3
(fºg)(x) = f(g(x)) = -2(-4x + 3) + 49
(fºg)(x) = 8x - 6 + 49
(fºg)(x) = 8x + 43
(fºg)(-5) = 8(-5) + 43
(fºg)(-5) = 3

in a 30-60-90 triangle,,
the long leg = x√3
short leg = x
hypotenuse (the side opposite the right angle marker) = 2x
since u know the long leg is 7√3, the short leg = 7

ou are buying batteries, a stereo, and some CDs from the I.B. Electronics store. You can buy from this store online or in a physical store. You have a coupon for 10% off that can only be used in the physical store and a $5.00 off coupon that can only be used online. The sales tax of 5% only applies to the physical store. Shipping for the online store is a flat rate of $6.99. You are trying to decide whether to shop at the physical store or the online store. Using the pricing information below, determine which store would cost less after all discounts, taxes, and shipping fees have been applied.
Item Quantity Physical Store Online Store
Batteries 2 packs $5.99/pack $4.99/pack
Stero 1 system $100.00/system $90.00/system
CDs 3 CDs $7.95/CD $8.95/CD
There is not enough information given.
It would cost less to purchase the items from the physical store.
It would cost less to purchase the items from the online store.
Answer:
It would be cheaper to use the online store
Step-by-step explanation:
the physical store added up to $129.04 and the online store was $128.82.
It would cost less to purchase the items from the physical store.
The correct option is C.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. Moreover, it is indicated by the symbol "%."
To calculate the total cost for each store, we need to take into account the discounts, taxes, and shipping fees.
For the physical store:
Batteries: 2 packs x $5.99/pack = $11.98
Stereo: 1 system x $100.00/system = $100.00
CDs: 3 CDs x $7.95/CD = $23.85
Subtotal: $135.83
After the 10% discount: $135.83 - 10% = $122.25
Sales tax: $122.25 x 5% = $6.11
Total cost: $122.25 + $6.11 = $128.36
For the online store:
Batteries: 2 packs x $4.99/pack = $9.98
Stereo: 1 system x $90.00/system = $90.00
CDs: 3 CDs x $8.95/CD = $26.85
Subtotal: $126.83
After the $5.00 discount: $126.83 - $5.00 = $121.83
Shipping fee: $6.99
Total cost: $121.83 + $6.99 = $128.82
Therefore, it would cost less to purchase the items from the physical store.
