Answer:
4,9
Step-by-step explanation:
since y = x+5, substitute the second equation into the first
then the first equation becomes x+5=2x+1
solve and you get x=4
substitute x for 4 in the second equation and you get y = 9

Lupitas Sister is Purchasing gas at the gas station. She buys 10 gallons of gas for $29.50
Write the and equation that represents the proportional relationship between number of gallons of gas purchased and the cost in dollars.
Answers
Step-by-step explanation:
10 gallons of gas is $29.50
10 gallons of gas = $29.50
10 gallons of gas / 10 = $29.50 / 10
1 gallon of gas = $2.95
Per x gallons of gas,
1 gallon of gas * x = $2.95 * x
x gallons of gas = $2.95 * x
Which of the following best describes the graph below?
Answers
Answer:
The correct option is;
A. It is a one-to-one function
Step-by-step explanation:
A function f(x), is a one to one function when each value in the range is given by each unique value in the domain such that each "x" value produces a unique "y" value.
The given graph has a domain of -2 ≤ x < ∞
Within the domain plotted in the graph, all lines with equation "x" = -2, -1, 0..., 4, 5 crosses the graph only once, therefore, for each value of "x", there is only one value of "y", which gives the relationship between the "x" and "y" values as one to one function

Lin notices that the number of cups of red paint is always 15 of the total number of cups (0.2 of the total number of cups). She writes the equation r = 15t (r = 0.2t) to describe the relationship. Which is the independent variable? Which is the dependent variable? Explain how you know.
Answers
Step-by-step explanation:
The number of cups of red paint is always 15 of the total number of cups. 0.2 of the total number of cups.
She writes the equation r = 15t (r = 0.2t) to describe the relationship.
In this case, the total no. of cups is an independent variable. No. of cups do not depend on any term.
The number of cups of red paint is a dependent variable as it depends on the number of cups.
Geraldine is asked to explain the limits on the range of an exponential equation using the function f(x) = 2x. She makes these two statements:
1. As x increases infinitely, the y-values are continually doubled for each single increase in x.
2. As x decreases infinitely, the y-values are continually halved for each single decrease in x.
She concludes that there are no limits within the set of real numbers on the range of this exponential function. Which best explains the accuracy of Geraldine’s statements and her conclusion?
Statement 1 is incorrect because the y-values are increased by 2, not doubled.
Statement 2 is incorrect because the y-values are doubled, not halved.
The conclusion is incorrect because the range is limited to the set of integers.
The conclusion is incorrect because the range is limited to the set of positive real numbers.
Answers
Answer:
The conclusion is incorrect because the range is limited to the set of positive real numbers.
Step-by-step explanation:
The conclusion is incorrect because the range of the function f(x) = 2x includes all positive real numbers.
What is a function?A relation is a function if it has only One y-value for each x-value.
Statement 1 is actually correct, because as x increases by 1, the value of f(x) = 2x is multiplied by 2.
Therefore, the y-values are indeed doubled for each single increase in x.
Statement 2, however, is incorrect, because as x decreases by 1, the value of f(x) is divided by 2, not halved.
Therefore, the accuracy of Geraldine's statements is mixed.
The range of the function f(x) = 2x includes all positive real numbers, not just integers or positive integers.
Therefore, the conclusion is incorrect because the range of the function f(x) = 2x includes all positive real numbers.

Tom earns £10 an hour and his wife earns £2 an hour more than Tom. Write a formula for their total earnings T for h hours.
Answers
Answer:
The formula for total earning is T = £22h
Step-by-step explanation:
Given that:
Per hour earning of Tom = £10
Per hour earning of Tom's wife = £10 + £2 = £12
Let,
T represent their total earnings
h be the number of hours
Total earnings = (Tom's per hour earning + His wife's per hour earning) * Number of hours
T = (£10+£12)h
T = £22h
Hence,
The formula for total earning is T = £22h

Rewrite the equation in slope intercept form
3y - 8x = -9
Answers
Answer:
y = (8/3)x - 3
Step-by-step explanation:
To get to slope intercept, just solve for y
3y - 8x = -9
3y = -9 + 8x
y = (-9 + 8x)/3
y = -9/3 + 8x/3 (distribute the 3 so we can reach the right form)
y = -3 + 8/3(x)
finally write in slope intercept form:
y = (8/3)x - 3
