what are two`fractions whose product is -3/5
To find two fractions whose product is -3/5, we can choose any two fractions that follow the rules of multiplying fractions. For example, the fractions 1/5 and -3/1 or -4/5 and 3/4 both have a product of -3/5.
Explanation:To find two fractions whose product is -3/5, we need to consider the rules of multiplying fractions. When we multiply two fractions, we multiply their numerators to get the new numerator and multiply their denominators to get the new denominator. In this case, we can choose any two fractions that satisfy these rules and have a product of -3/5.
For example, let's consider the fractions 1/5 and -3/1. When we multiply these fractions, we get (1 × -3) / (5 × 1) = -3/5.
Another example is the fractions -4/5 and 3/4. When we multiply these fractions, we get (-4 × 3) / (5 × 4) = -12/20, which can be simplified to -3/5.

Which ordered pair is a solution of the equation y = x – 3?
The ordered pair (5, 2) is the solution to the equation y = x - 3.
Explanation:
To find the solution to the equation y = x - 3, we need to substitute the x-value and see if the resulting y-value matches. Let's check each ordered pair:
For (-2, 5), substituting x = -2, we get y = -2 - 3 = -5, not a match.
For (-5, 2), substituting x = -5, we get y = -5 - 3 = -8, not a match.
For (2, 5), substituting x = 2, we get y = 2 - 3 = -1, not a match.
For (5, 2), substituting x = 5, we get y = 5 - 3 = 2, which is a match!
Therefore, the ordered pair (5, 2) is the solution to the equation y = x - 3.

Joe's age x, is 5 times his age 10 years ago. Which equation represents the statement?
a) x = 5x - 6
b) x = 5x + 6
c) x= 5 - 10x
d) x = 5(x - 10)
Answer:
d) X=5(X-10)
Step-by-step explanation:
Joe's age is change to X, so we know that his age today is 5 times his age 10 years ago.
His age ten years ago is X-10, if for example he is 25 today then his age ten years ago would be 15 (25-10).
If his age now is 5 times his age 10 years ago we will have to multiply his age ten years ago to get his age today.
Example:
5(X-10), this is how we can write 5 times his age 10 years ago, in a mathematical way.
Now we just have to know that this equation is equal to his age today X.
5(X-10) = X, or another way to put it is:
X=5(X-10)

A. y = 1.99(x - 4) + 11.96
B. y = 11.96(x - 4) + 1.99
C. y = 1.99x + 11.96
D. y = 11.96x + 1.99
Answer:
THE ANSWER IS A and I GO TO AMANA ACADEMY CHARTER SCHOOL
Step-by-step explanation:
Yunika downloaded four applications for $2.99 each to her cell phone. So, these four applications cost a total of $11.96.
Each remaining application that Yunika downloaded cost $1.99. Since represents the total number of applications, then ( - 4) represents the number of $1.99 applications she downloaded.
Therefore, the equation that can be used to find how much Yunika spent on cell phone application downloads is shown below.
= 1.99( - 4) + 11.96
Final answer:
The equation to represent the total amount spent by Yunika on cell phone application downloads is y = 1.99(x - 4) + 11.96, which corresponds to option A.
Explanation:
To find the equation representing the total amount spent by Yunika on cell phone application downloads, we can let y represent the total amount spent and x represent the total number of applications downloaded. As given, Yunika downloaded four applications at $2.99 each which gives us a fixed cost of 4 applications × $2.99 = $11.96. The remaining applications cost $1.99 each, so for every application after the first four, Yunika spends $1.99. The total amount spent, y, can thus be calculated by multiplying the number of additional apps (which is x - 4) by their cost ($1.99), and then adding the fixed cost ($11.96).
Therefore, the equation can be written as y = 1.99(x - 4) + 11.96, which matches option A. This equation takes into account both the initial fixed cost for the first four apps and the variable cost for the remaining apps.
Select the equation in which the graph of the line has a negative slope, and the y-intercept equals 10. Answer 10x + 5y = –25 5x – 10y = –12 20x + 5y = 50 2x + 6y = 10
The correct equation that represents a line with a negative slope and a y-intercept of 10 is 20x + 5y = 50, which rearranges to y = -4x + 10 in slope-intercept form.
Explanation:The question asks us to select the equation where the graph of the line has a negative slope and a y-intercept equal to 10. To find this, we need to rearrange each equation to the slope-intercept form, which is y = mx + b, where 'm' stands for slope and 'b' stands for y-intercept.
Let's analyze each equation:
10x + 5y = –25 rearranges to y = –2x - 5, having a slope of –2 and a y-intercept of -5.5x – 10y = –12 changes to y = 0.5x + 1.2, showing a positive slope of 0.5 and a y-intercept of 1.2.20x + 5y = 50 modifies to y = –4x + 10, which has a negative slope of –4 and a y-intercept of 10. This is the correct answer.2x + 6y = 10 turns into y = –1/3x + 10/6, having a negative slope of –1/3 but a y-intercept of 10/6.Thus, the correct equation is 20x + 5y = 50, which, when written in the slope-intercept form, displays a negative slope and meets our specification of a y-intercept equal to 10.
Final answer:
The equation with a graph that has a negative slope and a y-intercept of 10 is 20x + 5y = 50, when rearranged into slope-intercept form, it shows a slope of -4 and a y-intercept of 10.
Explanation:
To find the equation in which the graph of the line has a negative slope and a y-intercept equals 10, we need to convert the given equations into slope-intercept form, which is y = mx + b, where 'm' represents the slope and 'b' represents the y-intercept.
Starting with each equation:
10x + 5y = -25 can be rearranged to 5y = -10x - 25, and then y = -2x - 5. Here, the slope (m) is -2, which is negative, but the y-intercept (b) is -5, not 10.
5x - 10y = -12 rearranged gives -10y = -5x - 12, and then y = (1/2)x + 1.2. This line has a positive slope, not a negative.
20x + 5y = 50 is rearranged to 5y = -20x + 50, and then y = -4x + 10. This line has a negative slope (-4) and the y-intercept is 10, so this is the correct equation.
Finally, 2x + 6y = 10 rearranged gives 6y = -2x + 10, and then y = -(1/3)x + (10/6), which simplifies to y = -(1/3)x + 1.6667. The slope is negative, but the y-intercept is not 10.
Therefore, the correct equation is 20x + 5y = 50, because its graph has a negative slope and y-intercept of 10.
V(j+y)=61y+82 solve for y
A line has a slope of –3 and a y-intercept of 3.
What is the x-intercept of the line?
A: –9
B: –1
C: 1
D: 9
The x-intercept of a line with a slope of -3 and a y-intercept of 3 is 1(C). This is calculated by setting y = 0 in the equation of the line (y = -3x + 3) and solving for x.
Explanation:The question is asking for the x-intercept of a line with a slope of -3 and a y-intercept of 3.
The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Here, m = -3 and b = 3.
The x-intercept of a line is the x-coordinate where the line crosses the x-axis. At the x-intercept, the y-coordinate is 0 because it's on the x-axis. Therefore, we set y = 0 in our equation and solve for x: 0 = -3x + 3.
By adding 3x to both sides and then dividing by -3, we find that x = 1. So, the x-intercept of the line is 1(C).
