Answer: Quadrant III
Step-by-step explanation:
The slope is negative and the y-intercept is positive.
This means that it is impossible for both x and y to be negative, and thus it does not pass through Quadrant III
Which table correctly identifies the sample space of spinning the spinner and then selecting a card?
The table that correctly identifies the sample of spinning the spinner and then selecting a card is Option A.
What is a sample?A sample is a random element that belongs to a population. Another way to state it is that, it is a set of all the outcomes that are possible from a given set of events.
What is the explanation for the above?Table A accurately depicts each potential result. Along the column on the left is where you'll see the card outcomes.
The spinner's output is shown along the top row. The intersection of the left and top results appears in each cell.
For instance, row 1, and column 3 include "red, purple" to show that you received a card with the color "purple" and the color "red" on the spinner.
The labels on each cell in table A are accurate. At least one cell in the other tables (B, C, and D) contains an incorrect label.Table B's middle cell in the top row reads "blue, green" when it should read "blue, purple."Table C's upper left corner reads "green, green" when it should be "green, purple."In the bottom middle cell of Table D, "blue, blue" appears where "blue, green" should. Since there isn't a blue card, it is impossible to say "blue, blue."We can rule out options B through D using the three things outlined above.Learn more about samples at;

Solve using the factoring method: x2 + 4x - 21 = 0
Answer:
x² + 4x - 21 = 0
x² + 7x - 3x - 21 = 0
x ( x + 7 ) -3 ( x + 7 ) = 0
( x - 3 ) ( x + 7 ) = 0
∴ x - 3 = 0 or x + 7 = 0
x = 0 + 3 x = 0 - 7

Simplify fully 4d2-6d2+5d2
Answer:
3d²
Step-by-step explanation:
Hello!
To simplify, we combine the like terms by adding them.
Like termsLike terms are terms with the same variable and degree. A degree is a power to which the term is raised. Like terms can have numerical coefficients. For example, a coefficient of 4 to x² would mean 4 times x².
We can see that the variable d² is common throughout the three terms, meaning they are like terms. We can simply add and subtract them.
Simplify4d² - 6d² + 5d²-2d² + 5d²3d²The simplified form is 3d².
x-2y=15
x-3=4y
Simultaneous equation find x and y
Answer:
x = 27, y = 6
Step-by-step explanation:
x - 2y = 15
x - 4y = 3 (rearranged the orginal equation)
x - 2y = 15
- x - 4y = 3
___________
2y = 12
y = 6
Plug this value in any original equation
x - 2(6) = 15
x = 27
x and y of the simultaneous equation are 27 and 6 respectively.
Given,
x - 2y = 15
x - 3 = 4y
Here,
Equations:
x - 2y = 15
Rearranged the original equation
x - 4y = 3
Now subtract both equations,
x - 2y = 15
x - 4y = 3
⇒2y = 12
y = 6
Plug this value in any original equation
x - 2(6) = 15
x = 27
Thus the solution of system of equation is x = 27 and y = 6.

The molarity of the resulting solution is 3.99 × 10⁻⁴ M. The correct option is the third option 3.99 × 10⁻⁴ M
Molarity of a solutionFrom the question, we are to determine the molarity of the resulting solution
From the given information,
Number of moles = 5.99 × 10⁻⁶ mol
Volume = 1.50 × 10⁻² L
Using the formula,
Molarity = Number moles / Volume
∴ Molarity = (5.99 × 10⁻⁶) / (1.50 × 10⁻²)
Molarity = 3.99 × 10⁻⁴ M
Hence, the molarity of the resulting solution is 3.99 × 10⁻⁴ M. The correct option is the third option 3.99 × 10⁻⁴ M

The different values that could be be the greatest common divisor of the two integers are; 1, 2, 3, 4, 6
How to find the greatest common divisor?
Let the numbers be a, b. Thus, the product of the GCD(a, b) and the LCM(a, b) will be ab.
Now, for us to get something to be a factor of the GCD we need to make it be a factor of both a, b. Thus, its' square must be a factor of 180.

B. The radical is multiplied by a negative number.
C. 7 is added to the radical term.
D. The x-term inside the radical has a negative coefficient.
Option D is correct, which is : The x-term inside the radical has a negative coefficient.
Given, the domain of the square root function f(x) is x <= 7
Consider the function y = √x.
The domain of this function is x ≥ 0 and the range is y ≥ 0.
The expression inside the radical must be greater than or equal to zero.
Now, if x ≤ 7
x - 7 ≤ 0
7 - x ≥ 0
And the function y = √(7-x) will have the domain x ≤ 7.
This implies that the x-term inside the radical has a negative coefficient.

Using a linear function, it is found that 80 picnic tables can be produced for a total daily cost of 4,800.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Considering the daily fixed cost of 1200 as the y-intercept, and the variable cost of 45 as the slope, the linear function for the cost of producing n picnic tables is given by:
C(n) = 1200 + 45n.
Now, we have to solve for n when C(n) = 4800, hence:

Daniel and the agent made a total of
from the show.
Answer:
Amount in Blank total = $160
Amount of money Daniel’s agent made = $40
Amount of money Daniel and the agent made
from the show = $160
Step-by-step explanation:
this question is based on the calculation of percentages
so,
it is is given in the question that -
Daniel is a singer, and he promises his agent that he will give him a 25% commission based on what he makes from a show.
After paying the agent, Daniel takes home = $120
so,
let 'x' is the total amount of money that Daniel earned form the show
it is also given that Daniel promised to give 25 % to his agent from what he earned from the show
so, percentage of money left to the Daniel is
100-25 = 75%
therefore according to the question,
75percent of the x = $120
75/100×(x) = 120
3/4×(x) = 120
3x = 120×4
3x = 480
x = $160
so the total amount of money Daniel earned from the show is $160
Now we know that Daniel’s agent made 25% of the total amount of money earned from the show
therefore
25percent of 160 = Daniel’s agent made
25/100 ×160 = Daniel’s agent made
$40 = Daniel’s agent made
so the amount of money earned by Daniel’s agent made is $40
