Answer:
The required inequality is [tex](x-82)\geq 420[/tex].
Step-by-step explanation:
Let the total number of points scored = x
It is given that the team has already scored 82 points.
So, the points left to score are (x-82).
As, the team needs to score at least 420 points.
The inequality representing the situation is given by,
Points to score ≥ 420
i.e. [tex](x-82)\geq 420[/tex].
Hence, the required inequality is [tex](x-82)\geq 420[/tex].
Answer:
420≤x -82
Step-by-step explanation:
We need to score at least 420 points.
420≤ x
where x is the score we need to set the record
We have 82 points so far
420≤x -82
We still need to score x-82 points this season

Reflection about the y axis, and then about the x- axis
Step-by-step explanation:
When reflecting an object about the y- axis, the x-coordinates are multiplied with -1.
When reflecting an object about the x-axis, the y-coordinates are multiplied with -.
When reflecting about both axes, both coordinates are multiplied by -1.
Now looking at the coordinates of the two triangles:
A(2, -4) → A'(-2, 4)
B(5, -5) → B'(-5, 1)
C(4, -5) → C'(-4, 5)
All of the coordinates are multiplied by -1.
7x(x+1.8)=0 please help !
The solutions to the equation 7x(x+1.8)=0 are x = 0 and x = -1.8.
The highest power of the polynomial function is defined as the degree.
The Fundamental Theorem of Algebra asserts that a polynomial has n roots if its degree is n.
The equation is 7x(x+1.8)=0.
To solve this equation, we can use the property that if the product of two factors is equal to zero, then at least one of the factors must be zero.
Therefore, we set each factor equal to zero and solve for x:
7x = 0
x = 0
x + 1.8 = 0
x = -1.8
So, the solutions to the equation 7x(x+1.8)=0 are x = 0 and x = -1.8.
To solve the equation 7x(x+1.8)=0, set each factor equal to zero to find the two possible solutions for x, which are 0 and -1.8.
Explanation:To solve the equation 7x(x+1.8)=0, we need to set each factor equal to zero and solve for x.
Setting 7x=0, we find x=0. Setting x+1.8=0, we subtract 1.8 from both sides to get x=-1.8. Therefore, the solutions to the equation are x=0 and x=-1.8.
SEO Keywords: quadratic equation, solve, factor, solutionsThe given equation is 7x(x+1.8)=0. This is a quadratic equation that can be easily solved by setting each factor equal to zero. Here's how you can find the value(s) of x:
Set 7x equal to zero: 7x = 0 ---> x = 0.Set (x + 1.8) equal to zero: x + 1.8 = 0 ---> x = -1.8.Therefore, the two possible values for x are 0 and -1.8.

athaniel is using the quadratic formula to solve 0 = x2 + 5x - 6. His steps are shown below. What are the solutions to the equation? x = –1, 6 x = –6, 1 x = –22, 27 x = –27, 22
Answer:
x = - 6 or x = 1
Step-by-step explanation:
given a quadratic equation in standard form : ax² + bx + c = 0 : a ≠ 0
then the equation can be solved using the quadratic formula
• x = ( - b ± [tex]\sqrt{b^2-4ac}[/tex]) / 2a
x² + 5x - 6 = 0 is in standard form
with a = 1, b = 5 and c = - 6
x = (- 5 ± [tex]\sqrt{5^2-(4(1)(-6)}[/tex]) / 2
= (- 5 ± [tex]\sqrt{25+24}[/tex]) / 2
= (- 5 ± [tex]\sqrt{49}[/tex]) / 2
x = [tex]\frac{-5-7}{2}[/tex] = [tex]\frac{-12}{2}[/tex] = - 6
or x = [tex]\frac{-5+7}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1
The solutions to the quadratic equation x² + 5x - 6 = 0 are x = 1 and x = -6.
Explanation:To solve the quadratic equation x² + 5x - 6 = 0, Nathaniel used the quadratic formula.
The quadratic formula is x = (-b ± √(b² - 4ac)) / (2a), where a, b, and c correspond to the coefficients of the quadratic equation.
In this case, a = 1, b = 5, and c = -6.
Substituting these values into the quadratic formula, we get x = (-5 ± √(5² - 4(1)(-6))) / (2(1)).
Simplifying further, we have x = (-5 ± √(25 + 24)) / 2.
This yields two solutions: x = (-5 + √49) / 2 and x = (-5 - √49) / 2.
Simplifying the square root, we get x = (-5 + 7) / 2 and x = (-5 - 7) / 2.
Therefore, the solutions to the quadratic equation are x = 1 and x = -6.

A box contains10 pens, 5 of the pens are red, 4 are balck and 1 are bluem What is the probability of pulling out a black pen first, putting it back into the box, and then pulling a red pen ?
Final answer:
The probability of drawing a black pen first and then a red pen with replacement from a box of 10 pens is 20%.
Explanation:
To calculate the probability of drawing a black pen and then a red pen with replacement in a box that contains 10 pens, we should calculate the probability of each event separately and then multiply them since the events are independent.
There are 5 red pens, 4 black pens, and 1 blue pen, making a total of 10 pens. The probability of drawing a black pen is the number of black pens divided by the total number of pens: P(black) = 4/10 or 0.4.
Since the pen is replaced, the total stays the same. Therefore, the probability of then drawing a red pen is the number of red pens divided by the total number of pens: P(red) = 5/10 or 0.5.
To find the combined probability of both events happening in sequence (drawing a black pen and then a red pen), we multiply the two probabilities together: P(black and red) = P(black) × P(red) = 0.4 × 0.5 = 0.2 or 20%.

Lucy bought a 40-ounce bottle of vegetable oil for $7.69. She used 65% of the vegetable oil in three weeks. For the amount of vegetable oil she used in three weeks the approximate cost was?
To calculate the cost of the vegetable oil used by Lucy in three weeks, we need to determine the cost per ounce and then multiply it by the quantity used. In this case, the approximate cost of the oil used is $5.00.
Explanation:To find out the approximate cost of the amount of vegetable oil Lucy used in three weeks, we first need to figure out how much of the 40-ounce bottle she used. As the question states that she used 65% of it, we can calculate it as follows:
Firstly, to find 65% of 40 ounces, we can multiply 40 by 0.65, which gives us 26 ounces. So, this is the amount of oil Lucy used.Next, we need to find out how much does 26 ounces cost. To do this, we need to calculate the cost per ounce which is $7.69 (cost of the bottle) divided by 40 (the amount of ounces in the bottle). This gives us a cost of about $0.19225 per ounce.Now, to find the cost of 26 ounces of oil, we multiply the cost per ounce ($0.19225) by the amount of ounces used (26). So, $0.19225 * 26 = $4.9985 .So, the approximate cost for the amount of vegetable oil Lucy used in three weeks is $5.00, rounded to the nearest cent.

Find three ratios equivalent to 5/7
Answer:
10/14, 15/21
Step-by-step explanation:
WE are given a ratio 5/7
To find equivalent ratios it is sufficient to multiply both numerator and denominator by the same number
Let us take 2,3 for example.
When we multiply both numerator and denominator by 2, value does not change.
Hence we get equivalent fraction.
So 10/14 is one such fraction.
Next is multiply by 3
15/21 is another fraction.
The location of four game stops are on a coordinate grid are as follows:
Stop 1 at (−2,1)
Stop 2 at (−2, −7)
Stop 3 at (5,−7)
Stop 4 at (5, 1)
Paulo begins at Stop 1 and then walks to Stop 2, then Stop 3, and then Stop 4. Then he walks to Stop 1 again. The path between each stop is a straight line. One unit on the coordinate grid equals 125 feet.
What is the total distance Paulo walked?
Answer:
3750 feet
Step-by-step explanation:
Given that Paulo begins at Stop 1 and then walks to Stop 2, then Stop 3, and then Stop 4. Then he walks to Stop 1 again.
Where stops are given by coordinates:
Stop 1 at (−2,1)
Stop 2 at (−2, −7)
Stop 3 at (5,−7)
Stop 4 at (5, 1)
The path between each stop is a straight line. One unit on the coordinate grid equals 125 feet.
Now we need to find about what is the total distance Paulo walked.
So first we graph those points so that we can easily count the length of each side. then add each side to get the total length
length of rectangular path = 8+7+8+7=30
since one unit on the coordinate grid equals 125 feet. So to find the actual length we need to multiply 30 by 125 feet.
Hence final answer will be 125*30 = 3750 feet.

Answer: choice A
f(x) = (1/4)x^2, f(x) = -0.5x^2, f(x) = x^2
=======================================================
The coefficient in front of the x^2 term tells us how wide or narrow the parabola will be. It turns out that the further the coefficient value is from 0, in either direction, this will make the parabola more narrow.
Notice how 1/4 = 0.25 which is less than |-0.5| = 0.5 meaning that f(x) = (1/4)x^2 is wider than f(x) = -0.5x^2
Then comparing f(x) = -0.5x^2 to f(x) = 1x^2, we see that 0.5 is smaller than 1, so f(x) = -0.5x^2 is wider than f(x) = 1x^2
That is why the order from widest to narrowest is f(x) = (1/4)x^2, f(x) = -0.5x^2, f(x) = x^2
A graph shown below helps confirm the answer (note the color coding). In figure 1 is the graph of all three functions together. In figure 2, I reflect the second function help show the comparison of why it's the middle-most in terms of how wide it is (it is the orange parabola, which is the reflection of the red parabola)

Two cars got an oil change at the same auto shop. The shop charges customers for each quart of oil plus a flat fee for labor. The oil change for one car required 5 quarts of oil and cost $25.50. The oil change for the other car required 7 quarts of oil and cost $30.00. How much is the labor fee and how much is each quart of oil?
Answer:
The labor fee is $14.25, each quart of oil costs $2.25.
Step-by-step explanation:
Let $x be thee price of each quart of oil and $y be a flat fee for labor.
1. If the oil change for one car required 5 quarts of oil, then these 5 quarts cost $5x and together with a flat fee for labor it cost $25.50. Thus,
5x+y=25.50.
2. If the oil change for another car required 7 quarts of oil, then these 7 quarts cost $7x and together with a flat fee for labor it cost $30.00. Thus,
7x+y=30.00.
3. Subtract from the second equation the first one, then
[tex]7x+y-(5x+y)=30.00-25.50,\\ \\7x+y-5x-y=4.50,\\ \\2x=4.50,\\ \\x=\$2.25.[/tex]
Substitute it into the first equation:
[tex]5\cdot 2.25+y=25.50,\\ \\y=25.50-11.25,\\ \\y=\$14.25.[/tex]
The labor fee is $14.25, each quart of oil costs $2.25.
The labor fee is $14.25 and the cost per quart of oil is $2.25.
Explanation:To find the labor fee and cost per quart of oil, we can set up a system of equations using the given information. Let x represent the cost of each quart of oil and y represent the labor fee.
We have the equations:
5x + y = 25.50
7x + y = 30.00
We can solve this system of equations using substitution or elimination. Substituting y from the first equation into the second equation, we get:
7x + (25.50 - 5x) = 30.00
2x = 4.50
x = 2.25
Substituting x back into the first equation, we get:
5(2.25) + y = 25.50
11.25 + y = 25.50
y = 14.25
Therefore, the labor fee is $14.25 and the cost per quart of oil is $2.25.
