Answer:
I hope I didn't make mistakes, because I solved it without calculator
Step-by-step explanation:
[tex] \frac{5}{3} s + \frac{19}{15} = - \frac{3}{5} \\ \frac{5}{3} s = - \frac{3}{5} - \frac{19}{15} \\ \frac{5}{3} s = \frac{ - 9 - 19}{15} \\ \frac{5}{3} s = \frac{ - 28}{15} \\ s = - \frac{28}{15} \times \frac{3}{5} [/tex]
[tex]s = - \frac{28}{25} [/tex]
During a sale, a store offered a 40% discount on a bed that originally sold for $840. After the sale, the discounted price of the bed was marked up by 40%. What was the price of the bed after the markup? Round to the nearest cent.
Answer:
$705.60
Explanation:
Discounted price:
$840 × (100% - 40%)
= $840 × 60%
= $840 ÷ 100 × 60
= $504
Markup:
$504 × (100% + 40%)
= $504 × 140%
= $504 ÷ 100 × 140
= $705.60

The mapping diagram shows a relation. A mapping diagram shows a relation, using arrows, between inputs and outputs for the following ordered pairs: (negative 6, 0), (2, 1), (negative 7, negative 4), (11, 2), (3, 2). What is the domain of the relation? {x| x = –4 , 0, 1, 2}. {x| x = –7, –6, 2, 11, 3}. {y| y = –4, 0, 1, 2}. {y| y = –7, –6, 2, 11, 3}.
Answer:
b
Step-by-step explanation:
The domain is a set of input values so {x| x = –7, –6, 2, 11, 3} will be the domain of the relation therefore option (B) will be correct.
What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
The domain is for the independent variable while the range is for the dependent variable.
For example f(x) = x²
Now if we put x = 1 then it is called as domain variable while the value of function at x = 1 its that f(1) = 1 called range variable.
The domain is the set of all input values where the function is defined.
Since in the given relation ;
All input values have an output so all input values will be the domain of the given relation.
Hence "{x| x = –7, –6, 2, 11, 3} will be the domain of the relation".
For more details about the range and domain of the function,

Tom spent half of his allowance going to the movies. He washed the family car and earned 7 dollars. What is his weekly allowance if he ended with 15 dollars?
Answer:
Tom's weekly allowance is $16.
Step-by-step explanation:
With the information provided, first you have to subtract the amount he earned washing the family car from the total amount he had to determine the amount he had left from his allowance after going to the movies:
$15-$7=$8
Now, since the statement indicates that tom spent half of his allowance going to the movies, this means that the $8 represents the amount left after going to the movies and it is half of his allowance. So, you have to multiply this amount by 2 to find his weekly allowance:
$8*2=$16
According to this,the answer is that Tom's weekly allowance is $16.

Function c is defined by the equation c(n) = 50 + 4n. It gives the monthly cost, in dollars, of visiting a gym as a function of the number of visits, n.
Answer:
78 dollars
Step-by-step explanation:
Function c is defined by the equation c(n) = 50 + 4n. It gives the monthly cost, in dollars, of visiting a gym as a function of the number of visits, n. Find the value of c(7).
Given:
c(n) = 50 + 4n
Where,
c = monthly cost of visiting a gym
n = number of visits
Find the value of c(7)
That is, when n = 7
c(n) = 50 + 4n
c(7) = 50 + 4(7)
= 50 + 28
= 78
c(7) = 78 dollars

3x - 2y = -10
Answer:
m=3/2,y-int=5
Step-by-step explanation:
y=mx+b is the slope equation. since -10 is at the end of the equation and it does not have a variable next to it yk it is the y-intercept. if you want you draw this on a graph and you can see that you go up 3 and over 2

Step-by-step explanation:
The top and bottom points of the line are
(3,0) and (10,9)
[tex](x_1,y_1) = (3,0)\\\\(x_2,y_2) = (10,9)[/tex]
So,
[tex]\sf Slope = \frac{y_2-y_1}{x_2-x_1}\\\\Slope = \frac{9-0}{10-3} \\\\\boxed{\sf Slope = \frac{9}{7} }\\\\\rule[225]{225}{2}[/tex]
