Answer:
A) The worker is paid S= $ 1110 for producing 18 units.
B) The worker is paid $3,330 for producing x= 50 units.
Step-by-step explanation:
a) given x = 18 units
Time required T(x) = 4x+2
= 4(18)+2
= 72 +2
= 74 hrs
Amount paid S(T) = 15 T
= 15 ( 74) = $ 1110
b) Since S is given, S= $3,030
S(T)= 15 (T)
3030 /15= T
202 hrs= T
Now, we can find x:
T(x) = 4(x) +2
202 = 4x + 2
202-2 = 4x
200 / 4 =x
50 = x
so, worker produces 50 units.

Solve the system of linear equations.
x-y=5
-x+y=5
Is the answer H, I, J, or K
H. infinitely many I. no solution J. (0,5) K. (5,0)
Answer:
I would be our answer.
Step-by-step explanation:
So we need to solve both.
x-y=5 = 5.
And we also need to solve -x+y=5.
Let's regroup them.
[tex]y-x=5[/tex]
Now we needt to subtract y from both sides.
[tex]-x = 5 -y[/tex]
Now let's multiply both sides by -1.
[tex]x = -5 + y[/tex]
Then we finally get
x = y - 5
Our final answer is I, there is no solution for this problem. Yes, they both equal 5 but do not fit any of the answers.

Sonji paid $25.00 for two scarves, which were different prices. When she got home she could not find the receipt. She
remembered that one scarf cost $3 more than the other. What was the price of the more expensive scarf?
Answer:
$14
Step-by-step explanation:
Sony paid for two scarves = $ 25
We are given that one scarf cost $3 more than the other
Let the cost of one scarf be x
So, cost of another scarf = x+3
Since the total cost is $25
So, [tex]x+x+3=25[/tex]
[tex]2x+3=25[/tex]
[tex]2x=22[/tex]
[tex]x=\frac{22}{2}[/tex]
[tex]x=11[/tex]
So, cost of one scarf = $11
Cost of another scarf = x+3=11+3=14
Hence the cost of the expensive scarf is $14
A quadratic function has these characteristics:
x = 1 is the equation for the axis of symmetry.
x = –1 is an x-intercept.
y = –4 is the minimum value.
Determine the y-intercept of this parabola.
Explain your thought process.
Answer:
The y-intercept would be between 0 and -4 likely about -3.
Step-by-step explanation:
The y-intercept would be between 0 and -4 likely about -3.
Since the parabola has an axis of symmetry at x = 1 and a minimum of y = -4 then the vertex is (1,-4).
It has an x-intercept at x = -1 or (-1,0). This means from the vertex up to the x-intercept the function has to cross through the y-axis. This makes the y-intercept between 0 and -4 and likely at -3.
The y-intercept of the quadratic function given above is found to be at y = -3. This conclusion is reached by analyzing the vertex, its symmetry, and x-intercepts of the function, and applying these properties in the standard form of a quadratic function.
Explanation:The subject of this question is the properties of a quadratic function in mathematics. The given characteristics provide us with enough information to determine the y-intercept of the function. Let's analyze the information.
Since the axis of symmetry is 'x = 1', we know that the vertex of the parabola is at (1, y). Also, because it has a minimum value of 'y = -4', we know the y-coordinate of the vertex is -4. Therefore, the vertex of the parabola is at (1, -4).
An x-intercept at 'x = -1' means that (-1, 0) is a point on the parabola. From the nature of the symmetry of parabolas, we know that if there is a point (a, 0) on the parabola, there will also be a point on the other side of the axis of symmetry at (2h-a, 0), where 'h' is the x-coordinate of the vertex. So, we can calculate the other x-intercept as (2*1 - (-1), 0), which gives us (3, 0). Thus, a point on the parabola is also (3, 0).
Equipped with the vertex (1, -4) and a point on the parabola (3,0), we can use the form of a quadratic function y = a(x-h)² + k to determine the quadratic function. Substituting coordinates of the vertex into the formula for h and k, and the coordinates of the point into the formula for x and y, we get 0 = a(3-1)² + (-4). From that, we can solve for 'a', which equals 1.
So, our quadratic function is y = (x-1)² - 4. To find the y-intercept (the point where the function crosses the y-axis, where x=0), we substitute x=0 into our function, which yields y = (0-1)² - 4 = -3.
The y-intercept of the parabola is at y = -3.

What is the angles listed from descending order?
Answer:
RQ, RP, PQ
Step-by-step explanation:
The side opposite the largest angle is the largest side
Angle P at 105 is the largest angle so RQ is the largest side
Next largest angle is Q at 75, so RP is opposite it
The smallest angle is R, so the smallest side is opposite it, which is PQ
From largest to smallest
RQ, RP, PQ
Answer:
The correct answer is option 2
RQ > PQ > RP
Step-by-step explanation:
From the figure we can see that, a triangle PQR.
Three angles are given.
The angles are, <P = 105°, <R = 40° and <Q = 35°
To find the order of sides
We know that, the side opposite to the largest angle is the largest side, So we can write the three sides are in ascending order,
RQ > PQ > RP

Meghan counted the candies she had in a jar. She discovered that half of the candies were red. If she had 50 red candies, in which equation does x represent the total number candies in the jar?
50x2=x
50 represents the red candies.
2 represents the other half of candies.
x represents the total amount of candies.
Hope this helps!
The equation representing the total number of candies in Meghan's jar, where x is the total, is x/2 = 50, giving us 100 candies in total. For Jenny's chocolates, Jenny initially had 14 chocolates before she ate two and gave half of the remaining to Lisa.
If Meghan discovered that half of the candies were red and she had 50 red candies, then to find the equation representing the total number of candies in the jar, we assign x to represent the total number. Since half of x is 50, the equation is x/2 = 50. To find x, we multiply both sides of the equation by 2, resulting in x = 100. Therefore, Meghan has 100 candies in total in her jar.
To address the question about Jenny and her chocolates: Initially, Jenny has some number of chocolates. When she eats two chocolates and gives half of the remainder to Lisa, and Lisa ends up with six chocolates, we can determine how many Jenny started with. Lisa's six chocolates represent half of what remained after Jenny ate two, which implies there were 12 before giving to Lisa, and so initially, Jenny had 14 chocolates.
Harry's uncle gave him $62 to spend on basketball equipment. He bought 2 jerseys that cost $4 each, a basketball that cost $19, and a pair of shorts that cost $5. How much money does Harry have left?
Final answer:
Harry spent a total of $32 on basketball equipment, and since he started with $62, he has $30 left.
Explanation:
To calculate how much money Harry has left after purchasing basketball equipment, we need to add up the total cost of the items he bought and subtract that from the amount of money he was initially given. Harry bought 2 jerseys at $4 each, 1 basketball at $19, and a pair of shorts at $5.
Cost of 2 jerseys: 2 × $4 = $8
Cost of basketball: $19
Cost of shorts: $5
Now, we'll sum up the costs of these items to find the total expenses.
Total expenses = $8 + $19 + $5 = $32
Next, we'll find out how much money Harry has left after these purchases:
Money left = Initial amount - Total expenses
Money left = $62 - $32 = $30
So, Harry has $30 left after buying the basketball equipment.

False. Correct equation: [tex]\(2n - 7 = -5\)[/tex]. Your proposed equation [tex]\(7 - 5n = -5\)[/tex] does not accurately represent the relationship.
The answer is False.
Here's why:
1. The statement "seven less than twice a number" can be represented as [tex]\( 2n - 7 \)[/tex], where [tex]\( n \)[/tex] is the number.
2. The equation for "seven less than twice a number is negative five" should be [tex]\( 2n - 7 = -5 \)[/tex], as the phrase "is negative five" translates to the equation being equal to [tex]\( -5 \)[/tex].
3. Your proposed equation, [tex]\( 7 - 5n = -5 \)[/tex], is incorrect because it represents a different relationship. It suggests that [tex]\( 7 \)[/tex] subtracted by [tex]\( 5n \)[/tex] is equal to [tex]\( -5 \)[/tex], which does not align with the given statement.
4. To correct the equation, simply rewrite it as [tex]\( 2n - 7 = -5 \)[/tex], which accurately represents the relationship described in the statement.
Therefore, the statement is false because the given equation does not correctly represent the phrase "seven less than twice a number is negative five."
