motorcycle two years ago and paid $4,721 for it. It depreciated
35% during the two years. Is he losing money or making money
on this sale?
18. Willa is buying flowers for a large garden project. She plans
Answer:
Joel is losing money.
Step-by-step explanation:
4,721-35%=?
First, convert the percentage into a decimal.
35%=35/100=.35
Then multiply 4721 by .35 which is 1652.35
At last, subtract 4,721 by 1652.35= 3068.65

How to solve by completing the square??
x^2 +8x=33
We are given the equation x² + 8x = 33, and we need to solve it from completing the square, for which we will be following the below steps
Step 1 :- First, notice, what's the coefficient of x², if it's 1, then proceed to step 2, if not then divide both sides by the coefficient of x²
[tex]{:\implies \quad \sf x^{2}+8x=33}[/tex]
Step 2 :- Here, we need to develop a whole square in both sides somehow, so we have the coefficient of x, so add the square of half of coefficient of x on both sides :
[tex]{:\implies \quad \sf x^{2}+8x+{\bigg(\dfrac82\bigg)}^{2}=33+{\bigg(\dfrac82\bigg)}^{2}}[/tex]
Simplify both sides now :
[tex]{:\implies \quad \sf x^{2}+8x+(4)^{2}=33+(4)^{2}}[/tex]
Step 3 :- So now, here LHS is in the form of a² + 2ab + b², so we can just replace it by (a + b)², and we will keep simplifying RHS
[tex]{:\implies \quad \sf (x+4)^{2}=33+16}[/tex]
[tex]{:\implies \quad \sf (x+4)^{2}=49}[/tex]
[tex]{:\implies \quad \sf (x+4)^{2}=(\pm 7)^{2}}[/tex]
Step 4 :- As, power on both sides is 2, so we can just equate the bases
[tex]{:\implies \quad \sf x+4=\pm 7}[/tex]
Step 5 :- Equating x + 4 to 7, will yield x = 3, and equating it to -7, will yield x = -11, so we are now left with
[tex]{:\implies \quad \boxed{\bf{x=-11,3}}}[/tex]
A bag of apples weighs
4.25 pounds. How many
ounces
does the bag of apple
weigh?
Answer:
68 ounces
Step-by-step explanation:
Since 1 pound is 16 ounces, if you use the comparison 1 lb/16 oz=4.25 lb/x oz, you could see that by multiplying 4.25x1, you get 4.25 lbs. So you do the same for the ounces. 16x4.25=68 oz.
The bag of apple weigh is 68 ounces .
What is unit of measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
According to question
A bag of apples weighs = 4.25 pounds
and 1 pounds = 16 ounces
Therefore ,
4.25 pounds = 16*4.25 ounces
= 68 ounces
Hence, the bag of apple weigh is 68 ounces .

Write an equation of the
line that passes through
the given points (-3,-1)
(2, 2)
Answer:
[tex]y = \dfrac{3}{5}x + \dfrac{4}{5}[/tex]
Step-by-step explanation:
First, find the slope:
m = (change in y) / (change in x) = rise / run
m = (2 - (-1)) / (2 - (-3)) = (2 + 1) / (2 + 3) = 3/5
Then, write the equation of the line in point-slope form:
y - b = m(x - a) where (a, b) is a point on the line
y - 2 = (3/5)(x - 2)
Finally, solve for y:
[tex]y = \dfrac{3}{5}(x - 2) + 2[/tex]
[tex]y = \dfrac{3}{5}x - \dfrac{6}{5} + 2[/tex]
[tex]y = \dfrac{3}{5}x + \dfrac{4}{5}[/tex]

A company rents moving trucks for $45 plus $0.75 per mile. write an equation that relates the cost C and the miles driven, x. Calculate the cost of
renting a truck for one day, and driving it 110 miles.
The equation we would use here would be 45 + 0.75x = C
This is because we have a flat fee of $45 and you are being charged $0.75 per mile, so it depends on how many miles were driven.
To find out how much it would cost if it were to drive 110 miles, we simply put 110 in place of x;
45 + 0.75(110) = C
And now we solve!
45 + 82.50 = C
$127.50

Lets take it step by step!
Step 1 : first mutiply -1/2 * -1/3
-1/2 * -1/3 = 1/6
(remember to mutiply fractions we have to mutiply there denominator and numerator together)
Step 2 : then move on and multiply 1/6 * -1/4
1/6 * -1/4 =
-1/24
Step 3 : Next we have to go and multiply -1/24 by -1/5
-1/24 * -1/5 =

The length and breadth of a rectangular piece of paper are 18 cm and 15 cm respectively. By how much should be length be reduced keeping breadth constant to make area equal to 134 cm².....
Answer:
Area of a rectangle = length x breadth
Given:
area = 134 cm²breadth = 15 cm⇒ 134 cm² = length x 15cm
⇒ length = 134 ÷ 15
= 8.93333333... cm
Reduction in length = original length - new length
= 18 cm - 8.93333333... cm
= 9.07 cm (nearest hundredth)
The Davis family purchased a house last year. They put $20,000 towards a down payment and took out a $265,000 mortgage. Because it was a new home, all the repairs and maintenance were covered under the builder’s warranty, but the Davises want to budget this coming year for unexpected expenses. When estimating costs for home repair and maintenance, a good estimate is to budget 1% of the purchase price of a house. What would be a good yearly estimate of repairs and maintenance for the Davis family’s home? a. $28,500 b. $2,650 c. $2,850 d. $200
Answer:
2,850
Step-by-step explanation:
I'm not very good with percentages, so this may be incorrect, but 1 ℅ of the total purchase price would be 2850 because 1 ℅ is essential 0.01 x 285,000. 285,000 would be adding the down-payment to the mortgage.

What is the horizontal difference between (4, 8) and (-2, 2)?
Answer:
6 units
Step-by-step explanation:
the horizontal difference is the distance between the x values of both points. we know the distance between 4 and -2 is 6.
Pls help me get this. Right
Answer:
26 units
Step-by-step explanation:
so the horizontal distance between the two points is 24 units while the vertical distance is 10 units.
hence, we can use the pythagorean theorem to find the length of the diagonal.
the answer is equal to sqrt( 24^2 +10^2)
the answer is 26 units
also you should always remember that the diagonal is always greater in length than both the vertical and horizontal sides.

Easy function or not
Answer:
Problem 9: No

Step-by-step explanation:
Hello!
Problem 9:
This is NOT a function because one x-value has only one unique y-value. -2 is seen twice and the outputs, y, are given as 6 and 0.5. To be a function, each input has its own unique output. Two different inputs can have the same output.
Problem 10:
This IS a function, all inputs have unique outputs, and no repeating inputs are shown.
Terms:
x - values are also known as input, abscicca
y - values are also known as output, ordinate.
