A line passes through (-2,5) and has slope. What is an equation of the line in point-slope form?
Answers
Answer:
Step-by-step explanation:
since the question does not have a given slope you can just put the point into the point slope formula y-y1 = m(x-x1)
y-5 = m(x-(-2))
y-5 = m(x+2)
since the slope is not given, leave it like that

55 =50x+30y
-1(45) =(30x+30y)-1 = -45=-30x-30y
55 =50x+30y
+ -45=-30x-30y
10=20x
(1/20)10=20x(1/20)
0.50=x
3(55) =(50x+30y )3 = 165=150x+90y
-5(45) =(30x+30y)-5 = -225=-150x-150y
165 =150x+90y
+ -225=-150x-150y
-60=-60y
(1/-60)-60=-60y(1/-60)
1=y
A mechanical pencil costs _$0.50__ and a ruler costs __$1.00__.
e. Check your answer:
$55=50x+30y $45=30x+30y
$55=50(0.5)+30(1) $45=30(0.5)+30(1)
$55=25+30 $45=15+30
$55=$55 $45=$45
A mechanical pencil costs $0.50 and a ruler costs $1.00.
What is meant by cost?In calculus, a cost function is a mathematical formula used to determine how much it will cost to produce a certain number of units. The total cost formula is used to calculate the total cost by combining the variable and fixed costs of providing goods. Total cost = (average fixed cost x average variable cost) x number of units produced. A unit price is defined as a price expressed as a quantity of one, such as $25 per ticket or $0.89 per can. If you have a non-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the unit price, divide the terms of the ratio.The current answer as follows:
a. Fill in the blanks to calculate Mrs. Ortiz's purchase price. Let x denote the price of a pencil and y the price of a ruler.
$55 = 50x + 30y
b.Fill in the blanks with the cost of Mr. Donahue's purchase. Let x represent the cost of a pencil and y represent the cost of a ruler.
$45 = 30x + 30y
c. Circle the best method for solving the system:
Elimination
d. Solve the system using the method you chose.
55 = 50x + 30y - 1(45) = (30x + 30y) - 1 = -45 = -30x - 30y
55 = 50x + 30y + -45 = -30x - 30y
10 = 20x
(1/20)10 = 20x (1/20)
0.50 = x
3(55) = (50x + 30y )3 = 165 = 150x + 90y
-5 (45) = (30x + 30y) - 5 = -225 = -150x - 150y
165 = 150x + 90y + -225 = -150x - 150y
-60 = -60y
(1/-60) -60 = -60y (1/-60)
1 = y
A mechanical pencil costs $0.50 and a ruler costs $1.00.

Yes
Answers
Answer:
Yes.
Step-by-step explanation:
A function is a set of relations without repetitive domains.
From the given relation, there are no repetitive domains. Thus our relation here is a function.
Example of Function
{(1,1), (2,2), (3,3), (4,4), (5,5)}
Example of Non-Function
{(1,1), (1,2), (2,3), (3,4), (4,5)}
From this relation, there are two repetitive domains which are 1's. Thus not making the relation a function.

You are buying a tv that originally cost 1,050 you have a coupon for 15% off what is your new total for the tv.
Answers
Answer:
$892.50 ( Eight Hundred Ninety Two dollars and fifty cents)
Step-by-step explanation:
Just subtract 15% from 1050 (you also can check calculator if you want second opinion!)
(have a nice day)
This is because to find the percentage decrease of a number you must subtract the percentage from 100 . Then divide this number by 100 and multiply it with the original number . So I did 100-15= 85, 85/100= 0.85. 0.85 x 1050 = 892.50 which is the answer

After 12 years, a deposit of $10,000 into your college account has earned $6,000 in interest payments. What simple interest rate did the account earn
Answers
Answer:
5%
Step-by-step explanation:
I = PRT/100 where I = interest, P = initial deposit, R = the rate in %, T = number of years.
So substituting the given values:
6000 = 10000*R* 12/100
10000*12*R = 100*6000
R = 100*6000 / (10000 * 12)
R = 600000/120000
= 5%

An auditorium has 30 rows with 10 seats in the first row, 12 in the second row, 14 in the third row, and so forth. How many seats are in the auditorium? (1 point)

My answer is 1170 but the way I figured out the problem was by listing numbers 1-30. the problem state that the 1st row had 10, 2nd row had 12, and 3rd row had 14 and so forth. So I basically did the same method till I got to 30 and then add up all the numbers which gave me the answer of 1170.
Step-by-step explanation:
Answer:
1170
Step-by-step explanation:
hey there,
(the other person just calculated each number themselves then added them up which i guess is okay but not in the long term for when you're taking a test for example or your teacher asks you this kind of question so it's better to memorize a formula.)
< There are two types of sequences: arithmetic and geometric. So also two formulas for finding sums of each. This situation is an arithmetic sequence.
Formula for the sum of an arithmetic sequence: [tex]S_n=\frac{n}{2} (a_1+a_n)[/tex]
We know there are 30 total rows so n = 30. a1 is the very first term of a sequence so this is 10 in this situation. Before we fill in the formula, we should find what an is equal to.
For this, we will use the basic formula you learned previously: [tex]a_n=dn+c[/tex]
d (the common difference) = a2-a1 = 12-10=2
c (the common ratio) = a1-d = 10-2 = 8
an = dn + c = 2(30) + 8 = 68
Now that we have found what a_n is equal to, we can plug everything into the sum equation.
[tex]S_n = \frac{30}{2} (10+68)=1170[/tex]
So 1170 is your final answer. >
