Find an ordered pair (x,y) that satisfies both of the equations below:
2x - 3y = -5
5x - 2y = 4
Answers
Answer:
(2,3)
Step-by-step explanation:
Multiplying the first equation by 5 and the second equation by $-2$ gives
\begin{align*}
10x-15y&=-25,\\
-10x + 4y &=-8.\\
\end{align*}Adding the two equations gives $-11y = -33$, so $y=3$. Substituting $y=3$ in the first original equation gives $2x - 9 = -5$, so $2x = 4$ and $x = 2$. Therefore, the solution is $(x,y) = \boxed{(2,3)}$

take the square root of both sides
6 inches= w
Substitute to find length:
2w= 2(6)= 12 inches
CHECK:
72= 6 * 12
72= 72
ANSWER:
Width= 6 inches; Length= 12 inches
Hope this helps! :)
The width of the rectangle is 6 inches and the length is 12 inches.
Explanation:To find the dimensions of the rectangle, we can use the fact that the length is 2 times the width. Let's define the width as 'w' inches. According to the problem, the length is 2 times the width, so the length would be '2w' inches. The area of a rectangle is calculated by multiplying the length and the width, so we can set up the equation: 'w * 2w = 72'. Solving this equation, we find that 'w' equals 6 inches. Therefore, the width of the rectangle is 6 inches and the length is 2 times that, which is 12 inches.

A bike wheel is 26 inches it in diameter what is the bikes with your diameter in millimeters
Answers
To convert the bike wheel diameter from inches to millimeters, multiply 26 inches by the conversion factor of 25.4 mm/inch, resulting in a diameter of 660.4 mm.
Explanation:To convert the diameter of a bike wheel from inches to millimeters, we use the conversion factor that 1 inch is equal to 25.4 millimeters. Hence, we multiply the diameter in inches by this conversion factor.
The calculation will be:
Multiply the diameter in inches (26 inches) by the conversion factor (25.4 mm/inch).The diameter in millimeters is 660.4 mm (26 inches × 25.4 mm/inch).Therefore, the diameter of the bike wheel is 660.4 millimeters.

The measure of the width is 11ft
and the measure of the length is:
11+6=17ft
Final answer:
The width is 11 feet and the length is 17 feet.
Explanation:
The question asks us to find the length and width of a rectangle where the length is 6 feet longer than the width and the perimeter is 56 feet. To solve this, let's denote the width of the rectangle as w feet.
Since the length is 6 feet longer, the length will be w + 6 feet.
The formula for the perimeter (P) of a rectangle is P = 2(length + width). We can plug in our expressions for length and width into this formula:
P = 2(w + 6 + w)
Given that the perimeter is 56 feet, we have:
56 = 2(2w + 6)
Dividing both sides by 2, we get:
28 = 2w + 6
Subtract 6 from both sides:
22 = 2w
Divide both sides by 2:
11 = w
Therefore, the width of the rectangle is 11 feet and the length is w + 6 = 11 + 6 = 17 feet.

the function f(x)=40x-80 models the number of visitors a website received x days after it was created. Which is the most appropriate domain for function?
Answers
The most appropriate domain for the given function is x ≥ 0.
Explanation:The domain of a function represents the set of all possible input values, or x-values, for which the function is defined. In this case, the function f(x) = 40x - 80 represents the number of visitors a website received x days after it was created. Since time cannot be negative and the website exists only after it was created, the most appropriate domain for the function would be x ≥ 0. This ensures that the function is defined for all non-negative values of x, which aligns with the context of the problem.

Liam’s football team scored a total of 43 separate times this season, with a mix of touchdowns and field goals. Each touchdown is worth 7 points, and each field goal is worth 3 points. If the team scored a total of 301 points this season, how many touchdowns and field goals did they score?
Answers
Let a = number of touchdowns
Let b = number of field goals
a + b = 43
7a + 3b = 301
We can solve this system using the elimination method.
1. a + b - b = 43 + -b (add - b to both sides)
a = -b + 43
2. substitute -b + 43 for a in 7a + 3b = 301
7 (-b +43) + 3b = 301
-4b + 301 = 301 (simplify both sides of the equation)
-4b + 301 - 301 = 301 - 301 (add -301 to both sides)
-4b = 0
b = 0
Since b = 0, and b is the number of field goals, we know that Liam's team did not score any field goals. Which means the only points from his team came from touchdowns. So, 43 touchdowns were scored, and 0 field goals were scored, for a total of 301 points.
The football team scored 43 times this season, comprising solely of touchdowns worth 7 points each, totalling to 301 points. The team did not score any field goals worth 3 points.
Explanation:This problem can be solved using systems of linear equations. We have two equations here: 1. The total number of times the team scored, which is touchdowns(T) plus field goals(F) equals 43 (T+F=43). 2. The total points the team made, each touchdown being 7 points and each field goal being 3 points, equals 301 (7T + 3F = 301). By solving this system of equations, we can find the number of touchdowns and field goals.
From the first equation (T + F = 43), we can express T as (43 - F). Substitute T in the second equation: 7(43 - F) + 3F = 301, which simplifies to 301 = 301 - 4F. By rearranging, we get 4F = 0. Hence, F = 0. Returning to the first equation, T = 43 - F. As F=0, T = 43.
Thus, the team scored 43 touchdowns and 0 field goals.

A model rocket is launched from the ground with an initial velocity of 160 ft/sec. how long will it take the rocket to reach its maximum height? Show all work in the space provided. Assume the model rocket’s parachute failed to deploy and the rocket fell back to the ground. How long would it take the rocket to return to Earth from the time it was launched? Show all work in the space provided.
Answers
[tex]h(t)=-16t^2+v_0 t+h_0[/tex], where v₀ is the starting velocity and h₀ is the initial height. Using the velocity and starting height from our problem we have
[tex]h(t)=-16t^2+160t+0[/tex]. The path of this rocket will be a downward facing parabola, so there will be a maximum. This maximum will be at the vertex of the graph. To find the vertex we start out with [tex]x= \frac{-b}{2a}[/tex], which in our case is [tex]x= \frac{-160}{2(-16)}= \frac{-160}{-32} = 5[/tex]. It will take 5 seconds for the rocket to reach its maximum height. Plugging this back into our formula gives us
[tex]h(5)=-16(5^2)+160(5)+0 \\=-16(25)+800 \\=-400+800=400[/tex]
The rocket's maximum height is 400 feet.
We set our formula equal to zero to find the time it takes to hit the ground, then we factor:
[tex]0=-16t^2+160t+0 \\0=-16t^2+160t \\0=-16t(t-10)[/tex]
Using the zero product property, we know that either -16t =0 or t-10=0. When -16t=0 is at t=0, when the rocket is launched. t-10=0 gives us an answer of t=10, so the rocket reaches the ground again at 10 seconds.
Problem Safety standards require a pool to add 3 chlorine tablets to every 2,000 gallons of water. Today, the lifeguards at Park Pool added 8 chlorine tablets to their pool's 10,000 gallons of water. How does Park Pool's chlorine compare to the safety standards?
Answers
10,000 gallons of water is 5 times more than 2,000. So to achieve the safety standards , Park's pool must have 5 times the amount of chlorine it's necessary for 2.000 gallons.
3 chlorine tablets × 5 = 15 tablets
Mark would need to put 15 chlorine tablets to achieve safety standards
I hope you understood my brief explanation . And please consider marking this awnser as Branliest. Thank you! :)
Answer:
In the park's pool there are 7 less chlorine tablets as compared to safety standards.
Step-by-step explanation:
Number of chlorine tablets in 2,000 gallons water = 3 tablets
Number of tablets in 1 gallon of water = [tex]\frac{3}{2,000} tablets[/tex]
Number of tablet to be added in 10,000 gallons of water :
[tex]\frac{3}{2,000}\times 10,000 tablets=15 tablets[/tex]
Number of chlorine tablets added by lifeguard in 10,000 gallon water=8 tablets
Tablets of chlorine to be more added =
=15 tablets - 8 tablets = 7 tablets
In the park's pool there are 7 less chlorine tablets as compared to safety standards.

Factor y3−9y2+y−9 by grouping.
Answers

[tex]= y(y^2+1) - 9(y^2+1) [/tex]
[tex]= (y - 9)(y^2+1)[/tex]
Final answer:
To factor the expression y^3 - 9y^2 + y - 9 by grouping, divide it into two groups, factor out common factors, and note that (y - 9) is common to both, yielding the final factored form (y^2 + 1)(y - 9).
Explanation:
To factor by grouping the expression y3 − 9y2 + y − 9, we first split it into two parts where common factors are apparent:
(y3 − 9y2) and (y − 9)
Next, we factor out the common factors from each group:
y2(y − 9) + 1(y − 9)
Now, we notice that (y − 9) is a common factor in both terms. So, we factor (y − 9) out of the entire expression:
(y2 + 1)(y − 9)
This gives us the final factored form of y3 − 9y2 + y − 9, which is (y2 + 1)(y − 9).

Jimmy invest $16,000 in an account that pays 7.03% compounded quarterly. How long (in years and months) will it take for his investment to reach $23,000?
Answers
where:
[tex]P[/tex] is the investment
[tex]r[/tex] is the interest rate in decimal form
[tex]n[/tex] is the number of times the interest is compounded per year
[tex]t[/tex] is the time in years
[tex]A[/tex] is the amount after [tex]t[/tex] years
First, lets convert the interest rate to decimal dividing it by 100%:
[tex]r= \frac{7.03}{100} =0.0703[/tex]
Next, lets find [tex]n[/tex]. Since we know that the interest is compounded every 4 months (quarterly), it will be compounded [tex] \frac{12}{4} =3[/tex] times in a year, so [tex]n=4[/tex].
We also know that [tex]A=23000[/tex] and [tex]P=16000[/tex], so lets replace all the quantities into our compound interest formula:
[tex]25000=16000(1+ \frac{0.0703}{3})^{3t} [/tex]
[tex]25000=16000(1.0234)^{3t} [/tex]
Notice that the the number of years [tex]t[/tex] is in the exponent, so we have to use logarithms to bring it down. But first lets divide both sides by 16000 to isolate the exponential expression:
[tex] \frac{25000}{16000} =(1.0234)^{3t} [/tex]
[tex](1.0234)^{3t} = \frac{25}{16} [/tex]
[tex]ln(1.0234)^{3t} =ln( \frac{25}{16} )[/tex]
[tex]t= \frac{ln( \frac{25}{16}) }{3ln(1.0234)} [/tex]
[tex]t=6.43[/tex]
Now that we know [tex]t=6.43[/tex], the last thing to do is convert 0.43 years to months:
[tex](0.43 years)( \frac{12months}{1year} )=5.16months[/tex]
We can conclude that Jimmy's investment will take 6 years and 5 months to reach $25,000.
The length of rectangle ABCD is 4 in. The length of similar rectangle DEFG is 6 in. How many times greater than the area of ABCD is the area of DEFG?
Answers
is 6/4 of the length of the ABCD rectangle.
6/4=3/2 = 1,5
How many times greater than the surface of ABCD is the DEFG area?
1,5 times
The area of rectangle DEFG is 9/4 times greater than that of rectangle ABCD. This is determined by squaring the scale factor that relates their lengths, since the rectangles are similar.
The area of rectangle DEFG is how many times greater than the area of rectangle ABCD can be found by comparing the squares of their corresponding lengths, since they are similar rectangles. The length of rectangle ABCD is 4 inches, while the length of rectangle DEFG is 6 inches. To determine the area comparison, we square the scale factor, which is the ratio of the lengths of the two rectangles. This means the scale factor is 6/4, which simplifies to 3/2. Squaring this gives us (3/2)² = 9/4. Therefore, the area of DEFG is 9/4 times greater than the area of ABCD.
In the case of the squares Marta has, if one square has side lengths twice that of the other, the larger square will have an area that is 2² = 4 times larger than the smaller square. Applying this concept of squaring the scale factor to rectangles, as in the original question, gives us our ratio of areas between similar figures.
