Answer: the equation is 3x=12
Step-by-step explanation:
The coefficient is 3 because the coefficient is the number being multiplied by the variable (x).
To find the solution you have to divide both sides of the equation by 3 to find what times 3 will give you 12. After dividing both sides by 3 you get this equation. X=4
So this means that the solution is 4.

Find the slope of the line.
Answer:
slope = [tex]\frac{-1}{5}[/tex]
Step-by-step explanation:
Find the slope of the line using the slope formula, [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. The formula requires two points from the line - and looking at the graph, (1, 10) and (6, 9) are two points the line passes through (but any other points the line also passes through would work fine, too). So, substitute the points' x and y values into the formula and solve:
[tex]\frac{(9)-(10)}{(6)-(1)} \\= \frac{-1}{5}\\[/tex]
Therefore, [tex]-\frac{1}{5}[/tex] is the slope.

Marsha had $4.00 in her pocket in the morning, and Mark had $0.50. Marsha sells her sweets for $0.25 each, and Mark sells his for $0.50 each.
If Marsha and Mark both sold the same number of sweets, and they have the same amount of money at the end of the day, how many sweets did they each sell?
Answer:
So is it 29 sweets
Step-by-step explanation:
Marsha and Mark both sold 14 numbers of sweets each.
To understand more, check below explanation.
Equation in one variable:Let us consider that Marsha and Mark both sold x number of sweets each.
Since Marsha sells her sweets for $0.25 each.
Amount Marsha earns = 0.25x
Mark sells his for $0.50 each.
Amount Mark earns = 0.50 x.
Given that, Marsha had $4.00 in her pocket in the morning, and Mark had $0.50.
4 + 0.25x = 0.50 + 0.50x
0.25x = 3.5
x = 3.5/0.25
x = 14
Hence, Marsha and Mark both sold 14 numbers of sweets each.

In a group of 44 students, 11 study both Art and Biology. 10 study Biology but not Art. 2 study neither subject. Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?
Answer:
1/4 or 0.25
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that 11 study both Art and Biology and there are 44 students in class. To determine the probability that a student picked at random studies Art and Biology,
the number of possible outcome = 11
number of total outcome = 44
the probability the student studies Art and Biology
= 11/44
= 1/4
= 0.25

If the polynomials ax^3 + 4x^2 + 3x - 5 and x^3 - 3x^2 - 5x + a leave the same remainder when divided by (x-3) and (x+2) respectively, find the value of a.....
Given:
The polynomials [tex]ax^3+4x^2+3x-5[/tex] and [tex]x^3-3x^2-5x+a[/tex] leave the same remainder when divided by (x-3) and (x+2) respectively.
To find:
The value of a.
Solution:
Remainder theorem: If a polynomial p(x) is divided by (x-c), then the remainder is equal to p(c).
The polynomials [tex]f(x)=ax^3+4x^2+3x-5[/tex] is divided by (x-3). So, the remainder is f(3).
[tex]f(3)=a(3)^3+4(3)^2+3(3)-5[/tex]
[tex]f(3)=27a+36+9-5[/tex]
[tex]f(3)=27a+40[/tex]
The polynomial [tex]g(x)=x^3-3x^2-5x+a[/tex] is divided by (x+2). So, the remainder is g(-2).
[tex]g(-2)=(-2)^3-3(-2)^2-5(-2)+a[/tex]
[tex]g(-2)=-8-12+10+a[/tex]
[tex]g(-2)=-10+a[/tex]
It is given that the remainders are same. So,
[tex]f(3)=g(-2)[/tex]
[tex]27a+40=-10+a[/tex]
[tex]27a-a=-10-40[/tex]
[tex]26a=-50[/tex]
Divide both sides by 26.
[tex]a=\dfrac{-50}{26}[/tex]
[tex]a=\dfrac{-25}{13}[/tex]
Therefore, the value of a is [tex]\dfrac{-25}{13}[/tex].
QR is a diameter and Q(1,8) and C(3.5,2) are points on a coordinate plane. Find and state the coordinates of Point R
Answer:
The coordinates of point R are [tex]R(x,y) = (6, -4)[/tex].
Step-by-step explanation:
From Geometry we understand that magnitude of Diameter is twice the magnitude of Radius. Vectorially speaking, both radius and diameter are collinear. That is:
[tex]\overrightarrow{QR} = 2\cdot \overrightarrow{QC}[/tex] (1)
Where:
[tex]\overrightarrow{QC}[/tex] - Vector radius.
[tex]\overrightarrow{QR}[/tex] - Vector diameter.
If we know that [tex]Q(x,y) = (1,8)[/tex] and [tex]C(x,y) = (3.5,2)[/tex], then coordinates of point R are, respectively:
[tex]R(x,y) -Q(x,y) = 2\cdot C(x,y)-2\cdot Q(x,y)[/tex]
[tex]R(x,y) = 2\cdot C(x,y) -Q(x,y)[/tex]
[tex]R(x,y) = 2\cdot (3.5, 2) - (1,8)[/tex]
[tex]R(x,y) = (6, -4)[/tex]
The coordinates of point R are [tex]R(x,y) = (6, -4)[/tex].
