Answer:
Dude their answers are the same
Step-by-step explanation:
Adding a negative is the same as subtracting
Answer:
Yes, they're both correct
Step-by-step explanation:
They are both correct because both equations are equal. You could rewrite 7x + (-3) as 7x + 1(-3) and when you "distribute" the positive 1 the equation becomes 7x-3 which is the same thing as 7x-3. When you're subtracting 1 you're also technically adding negative 1

The operating costs of a swimsuit distributor are $120,000 per year plus $23 per swimsuit. The current partners have
500,000 to spend and are considering a new partner who has $150,000. How many swimsuits can they produce with and
without the new partner?
The swimsuits that can be produced with the new partner is 23,043.
The swimsuits that can be produced without the partner is 16,521.
How many swimsuits can be produced?The equation that relates total cost, operating cost and cost per swimsuit together is
Total cost = operating cost + (cost per swimsuit x number of swimsuits)
500,000 = 120,000 + ($23x s)
500,000 - 120,000 = 23s
380,000 = 23s
s = 380,000 / 23
s = 16,521
Number of swimsuits that can be produced with the new partner:
(500,000 + 150,000) = 120,000 + ($23x s)
650,000 = 120,000 + 23s
650,000 - 120,000 = 23s
530,000 = 23s
s = 530,000 / 23
s = 23,043

The line equation in slope - intercept form is
Answer:
y = -4x + 25
Step-by-step explanation:
You are given the slope, but you can find the slope using 2 points. Slope is the change in y over the change is x. Your two y's are 1 and 9. Your two x's are 6 and 4.
1-9/6-2
1 - 9 = -8
6-4 = 2
-8/2 is -4.
We want an equation in the form y = mx +b. We have the m (slope), we now just need the b. We take either of the ordinal points (4,9) or (6, 1) to find b. They will both work, but the question tells us to us (4,9). 4 is the x and 9 is the y.
y = mx + b
9 = (-4)(4) + b a negative times a positive is a negative.
9 = -16 + b Add 16 to both sides
25 = b
We know now m which is -4 and b which is 25. We plug them into the model y = mx + b
y = -4x + 25

[tex]w = 2 \left(\cos\left(\dfrac\pi{16}\right) + i \sin\left(\dfrac\pi{16}\right)\right)[/tex]
The product [tex]zw[/tex] is obtained by multiplying the moduli and adding the arguments. In other words
[tex]z = |z| e^{i\arg(z)} \text{ and } w = |w| e^{i\arg(w)} \implies zw = |z||w| e^{i(\arg(z)+\arg(w))}[/tex]

John needs 150 feet of rope to section off part of his barn. At a local hardware store he can buy a 30 yard spool for $24 or he can buy 150 foot at $.25 per foot. Which is the better buy?
Answer:
30 yards for 24 vs 1 foot for 25 cents
so lets multiple the yards by 3 to see how many feet
90 feet = 30 yards
90 feet 24 dollars
now lets divide 90 by 24
3.75 so 3.75 per foot
so the second one is way better
Hope This Helps!!!
Answer:
150 feet at $.25 per foot ($.75 per yard) is the better buy.
Step-by-step explanation:
150 feet is equal to 50 yards. So 2 30-yard spools would be $48. $48 for 60 yards equals $.80 per yard. So 150 feet at $.25 per foot ($.75 per yard) is the better buy.

m = [tex]\frac{y2-y1}{x2-x1}[/tex]
m = [tex]\frac{10-(-8)}{1-1}[/tex]
m = 18/0
In order to find the slope, we have the formula is
The change of Y (Also Y minus each other)
----------------------------------------------------------------- Over (As fraction
The change of X (Also X minus each other)
Now the first point is (1,10) The Y is 10
The X is 1
Now the Second Point is (1,-8) The Y is -8
The X is 1
So now we plug the numbers in
10-(-8)
--------- which is equal to 18/0

The adjacent sides of the parallelogram are (x + 3) and (x + 2). Find the perimeter of the parallelogram.
Answer:
P = 4x+10
Step-by-step explanation:
So a parallelogram has 2 set of sides which are parallel and equal. So if you're given two adjacent sides, that means you're given a side from each set of sides, which are equal. This means the perimeter is simply: 2(x+3) + 2(x+2). This can be further simplified by distributing the 2 which gives you the equation: 2x+6+2x+4, which further simplifies to 4x+10.

What is the weighted average cost of capital if a business has a cost of equity of 12%, a cost of debt of 10%, tax rate of 25%, 20 million market value of debt, and 60 million market value of equity?
If the cost of equity is 12% , cost of debt 10%, tax rate 25%, 20 million market value of debt , 60 million market value of equity then the weighted average cost of capital is 10.875%
Given cost of equity is 12% , cost of debt 10%, tax rate 25%, 20 million market value of debt , 60 million market value of equity.
We know that weighted average cost of capital= cost of equity* weight of equity+ cost of debt* weight of debt.
Cost of debt (consider after tax)=10%(1-25%)
=10%*0.75
=0.075
Weight of equity=60/80
=0.75
Weight of debt=20/80
=0.25
Weighted average cost of capital=12%*0.75+0.075*0.25
=0.09+0.01875

Answer:
200 cupcakes
Step-by-step explanation:
12 cupcakes = 6%
12/x=6/100 6x=1200 x=200
so 200 cupcakes
hope this helps
The total number of cupcakes the bakery sells that day is 200.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
Given that,
A bakery sold 12 vanilla cupcakes in a day, which is 6% of the total cupcakes.
Let's say the total cupcakes were x
Then,
6% of x = 12
6 × x/100 = 12
Divide both sides by 6
x/100 = 2
Multiply both sides by 100
x = 200

Then g(x) is a translation of 3 units downwards of f(x). The correct option is B.
How the graphs are related?
Here we have:

In terms of the trigonometric ratios for ΔBCE, what is the length of CE? Insert text on the triangle in GeoGebra to show the length of CE. Take a screenshot of the triangle with the text, save it, and insert the image in the space below.
By applying the law of cosine, the length of side CE is equal to 9.22 cm and the image of right-angled triangle BCE is shown in the image attached below.
How to calculate the length of CE?In order to determine the length of side CE, we would apply the law of cosine because both side CE and side BC respectively represent the adjacent side and hypotenuse of right-angled triangle BCE.
cos(θ) = Adj/Hyp
Where:
Adj is the adjacent side of a right-angled triangle.Hyp is the hypotenuse of a right-angled triangle.θ is the angle.Substituting the parameters into the formula, we have;
cos(θ) = CE/BC
cos(11.46) = CE/9.41
Cross-multiplying, we have:
CE = 9.41 × cos(11.46)
CE = 9.41 × 0.9801
CE = 9.22 cm.
By applying the law of cosine, the length of side CE is equal to 9.22 cm and the image of right-angled triangle BCE is shown in the image attached below.
