Answer:
A) Original price : y =10.x
Cheaper brand : y = 7x
The original box is $3 more than the cheap one.
Proof: Suppose 1 box is bought of each (x=1),Original will cost $10 & the Cheaper Price is $7
B) Each time he buys a cheap brand he save $3 ($10-$7).
On 5 cheap boxes, He would save $3 x 5 boxes = $15.
Step-by-step explanation:
Part A: The price of the first cereal that Yani bought was $10 and he new cereal is $7.
$10 - $7 = $3. The original box of cereal was $3 more than the super- saving cereal.
Part B: Yani will save $15 each month.
With the $10 cereal he used to pay $50 per month. Now with the super-saving cereal, he will now pay $35 per month.
So we need to subtract $50 - $35 = $15
The answer for part A is Original price: y =10x and Cheaper brand: y = 7x, and for part B he would save boxes $15.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Yani buys a certain brand of cereal that costs $10 per box.
Yani changes to a super-saving brand of the same size.
= $10 - $7 = $3.
Yani will save $15 each month.
= $50 - $35 = $15
Thus, the answer for part A is Original price: y =10x and Cheaper brand: y = 7x, and for part B he would save boxes $15.

Answer:
AE = 30
GD = 5
GF = 10
Step-by-step explanation:
Centroid of medians divide median in the ratio 2 : 1
Therefore,
AG : GE : 2 : 1
Let AG = 2x & GE = x
Since, AG = 20....(given)
Therefore, 2x = 20
x = 20/2
x = 10
GE = x = 10
AE = AG + GE = 20 + 10 = 30
CG : GD : 2 : 1
Let CG = 2x & GD = x
Since, CG = 10....(given)
Therefore, 2x = 10
x = 10/2
x = 5
Since, GD = x
Therefore, GD = 5
BF = 30
2x + x = 30
3x = 30
x = 30/3
x = 10
GF = 10

Answer:
y=-1/4x+1
Step-by-step explanation:
The perpendicular equations slope is the negative reciprocal of the other lines, so if I had 2 as a slope, the perpendicular line's slope would be -1/2, I think. Then you just use the found slope and the given point to solve for b, then use the b value you get for the final equation.
4. When simplified, what is the value of 175, if i2 = – 1.
Answer:
5i[tex]\sqrt{7}[/tex]
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]
i² = - 1 ⇒ i = [tex]\sqrt{-1}[/tex]
Given
[tex]\sqrt{-175}[/tex]
= [tex]\sqrt{25(7)(-1)}[/tex]
= [tex]\sqrt{25}[/tex] × [tex]\sqrt{7}[/tex] × [tex]\sqrt{-1}[/tex]
= 5i[tex]\sqrt{7}[/tex]
Answer:
[tex]5i\sqrt{7}[/tex]
Step-by-step explanation:
In order to solve this question we need to know how to multiply roots. You will need to understand that when we multiply [tex]\sqrt{a}[/tex] by [tex]\sqrt{b}[/tex], the following is true.
[tex](\sqrt{a})(\sqrt{b}) = \sqrt{ab}[/tex] (1)
From the question it self we know that [tex]\sqrt{ab}[/tex] is equal to [tex]\sqrt{-175}[/tex]. We also know that [tex]i^{2} = -1[/tex] or in other words [tex]i = \sqrt{-1}[/tex].
Now we will need to factors [tex]\sqrt{-175}[/tex] so that at the end we will end up representing [tex]\sqrt{-175}[/tex] as a product of [tex]\sqrt{-1}[/tex] and some other number. In order to determine the unknown number we will just have to divide [tex]\sqrt{-175}[/tex] by [tex]\sqrt{-1}[/tex]. From the equation (1) that I mention at the start we can figure out that......
[tex]\sqrt{a} = \frac{\sqrt{-175} }{\sqrt{-1} } = \sqrt{175}[/tex] (in our case [tex]\sqrt{a}[/tex] is the unknown number we are trying to find)
Now we can rewrite [tex]\sqrt{-175}[/tex] as the following.....
[tex]\sqrt{-175} = (\sqrt{175})(\sqrt{-1})[/tex]
From here we substitute [tex]\sqrt{-1}[/tex] with [tex]i[/tex] and simplify [tex]\sqrt{175}[/tex]. In order to simplify [tex]\sqrt{175}[/tex] we will have to factor [tex]\sqrt{175}[/tex] in a way that we will see [tex]\sqrt{175}[/tex] as a multiple of a perfect square root. An so we get the following
[tex]\sqrt{-175} = (\sqrt{175})(i) = (\sqrt{7})(\sqrt{25} )(i) = (\sqrt{7})(5)(i) = 5i\sqrt{7}[/tex]

Which equation is a line that is parallel to the x-
axis and passes through the point (5,2)?
Answer:
y = 2
Step-by-step explanation:
Since the line is parallel to the x-axis,
the gradient, m = 0
From the point, we know that
x = 5
y = 2
So y = 2 is the line that parallel to x-axis

Show your work F(x)=5x^2-4x+1 G(x)=3x-2 H(x)=x+1 K(x)= 4x What is (g*h)(x)= What is g(k(x))= What is k(g(0)) =
Answer:
— What is (g × h)(x)?
The answer is 3x²+x-2
— What is g(k(x))?
The answer is 12x - 2 or 2(6x-1)
— What is k(g(0))
The answer is -8
Explanation:
Given these functions —
[tex]f(x) = 5 {x}^{2} - 4x + 1 \\ g(x) = 3x - 2 \\ h(x) = x + 1 \\ k(x) = 4x[/tex]
Find (g × h)(x)
[tex](g \times h)(x) = g(x) \times h(x)[/tex]
Substitute g(x) = 3x - 2 and h(x) = x + 1
[tex](3x - 2) \times (x + 1) \\ (3x - 2)(x + 1)[/tex]
Multiply the polynomial.
[tex]3 {x}^{2} + 3x - 2x - 2[/tex]
Subtract - 2x out of 3x —
[tex]3 {x}^{2} + x - 2[/tex]
Thus, the answer is —
[tex](g \times h)(x) = 3 {x}^{2} + x - 2[/tex]
Find (g(k(x))
Substitute k(x) = 4x in g(x).
[tex]g(x) = 3x - 2 \\ k(x) = 4x[/tex]
[tex]g(k(x)) = g(4x)[/tex]
[tex]g(4x) = 3(4x) - 2[/tex]
Distribute 3 in 4x —
[tex]g(4x) = 12x - 2[/tex]
Thus the answer is —
[tex]g(k(x)) = 12x - 2[/tex]
Alternative Solution
[tex]g(k(x)) = 2(6x - 1)[/tex]
Find k(g(0))
Given two functions — k(x) and g(x)
[tex]k(x) = 4x \\ g(x) = 3x - 2[/tex]
Evaluate the value of g(0) as we substitute x = 0 in g(x)
[tex]g(0 ) = 3(0) - 2 \\ g(0) = 0 - 2 \\ g(0) = - 2[/tex]
Since we need to find k(g(0)), our currently input is g(0).
From k(x) and g(0) —
[tex]k(x) = 4x \\ g(0) = - 2[/tex]
Substitute g(0) = -2 in k(x)
[tex]k(g(0)) = 4(g(0)) \\ k( - 2) = 4( - 2) \\ k( - 2) = - 8[/tex]
Thus, the answer is —
[tex]k(g(0)) = - 8[/tex]

Answer:
partial products: 0.25, 1.5, 0.50, 3Zoe spent $5.25 on applesStep-by-step explanation:
The partial products are apparently derived by multiplying parts of each value on either side of the decimal point:
1.5 × 3.50 = (1 + 0.5)(3 + 0.50) = 1×3 + 0.5×3 +1×0.50 +0.5×0.50
= 3 + 1.5 + 0.50 + 0.25 . . . . . partial products
Their sum is ...
3 + 1.5 + 0.50 + 0.25 = 5.25

What is the slope of (-9, 8) and (3,- 12)
Answer:
Your slope would be -5/3
Step-by-step explanation:
To find the slope from two points, you would use the formula y2-y1/x2-x1
In this case, the equation would look like -12-8/3-(-9)
-12 - 8 = -20
3 - (-9) = 12
-20/12 = -5/3
It takes 404040 ink cartridges and 200200200 pages to print a book, and it takes 303030 ink cartridges and 808080 pages to print a magazine. Sarah wants to print books and magazines with at most 300300300 ink cartridges and 120012001200 pages. Let BBB denote the number of books she prints and MMM the number of magazines she prints.
Answer:
40B +30M ≤ 300
200B +80M ≤ 1200
Step-by-step explanation:
The inequality functions are as follows:
For 40 cartridges per book and 30 cartridges per magazine and at most 300 cartridges are used
So the function would be
40B +30M ≤ 300
Now the another would be
There are 200 pages for printing a book and 80 pages are required for printing a magazine also she used at most 1,200 pages
So, the function would be
200B +80M ≤ 1200
