find y- intercept
Answer:
3
Step-by-step explanation:
subtract 3y from both sides
add 9 to both sides
3y=12x+9
divide everything by 3
y=4x+3
y-intercept is 3

What is the value of x?
Answer:
x = 30 degrees
Step-by-step explanation:
Okay so we start by noticing that the two pointed out vertices = 180 degrees. So we have the following equation.
(x + 12) + (3x + 48) = 180
If you combine them you get:
4x + 60 = 180
Subtract 60 from both sides..
4x = 120
Divide both sides by 4..
x = 30
And there's your answer!

In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Joyce has scored 90, 93, and 85 on the first three. What range of scores on the fourth test will give Joyce a C for the semester (an average between 70 and 79, inclusive)? Assume that all test scores have a non-negative value.
Express your answer in interval notation.
HELP ASAP BRAINLEST AND THANKS
Answer:
[12,48]
Step-by-step explanation:
We will start by calculating the score she needs to get a 70 in the class
We will let x equal the fourth test
[tex]\frac{90+93+85+x}{4} =70[/tex]
This isn't hard to solve and we will do so by multiplying 4 by both sides and subtracting 268 (90+93+85)
This means that x= 12
We will then use the same formula but set it equal to 79
[tex]\frac{90+93+85+x}{4} =79[/tex]
We solve x in the exact same way and get x=48
our final answer is now [12,48]
In the figure, a∥e, m∥n, and m∠1 = 108°.
What is the m∠3?
Enter your answer in the box.
°
Lines n and m (reading from top to bottom) are parallel to each other, and lines a and e are parallel to each other. The two pairs of lines intersect each other. Lines m and n start at top left and drop to the bottom right. Lines a and e rise from left to right. Only six of the sixteen angles created are labelled. Angle one is the top angle made by lines n and a. Angle two is the bottom angle. Angle three is the bottom angle made by lines m and a. Angle four is the top angle made by lines n and e. Angle five is the left angle. Angle six is the bottom angle made by lines m and e.

factor 18v⁹+33v⁸+14v⁷ completely
Answer:
[tex]v^{7}[/tex] x (6v+7) x (3v+2)
Step-by-step explanation:
18v^9 + 33v^8 +14v^7
Factor out v^7 from the expression
v^7 x (18v^2+33v+14)
write 33v as a sum
v^7 x (18v^2+21v+12v+14) *like this 21v+12v
Factor out 3v from the expression
v^7 x (3v x (6v+7)+12v+14)
Factor out 2 from the expression
c^7 x (3v x (6v+7)+2(6v+7)
Factor out 6v+7 from the expression
v^7 x (6v+7) x (3v+2)
If 39 is 10% of an number what is the number? How did you find your answer?
Answer:
390
Step-by-step explanation:
10% = 39
39 x 10 = 390
390 = 100%
Answer:
x=390
Step-by-step explanation:
x of 10% equal to 39
x10/100 = 39
x10 =3900
x = 3900/10
= 390
(8,-7)m=-3/4 write an equation in point slope form of the line that passes through the given point and has the given slope
Answer:
Equation of the straight line in point-slope form
y -(-7) = [tex]\frac{-3}{4}[/tex](x-8)
Equation of the straight line
3x +4y +4=0
Step-by-step explanation:
Explanation:-
Given that the point ( 8,-7) and [tex]m = \frac{-3}{4}[/tex]
Equation of the straight line passing through the point (x₁, y₁) and having slope 'm'
y - y₁ = m (x-x₁)
y -(-7) = [tex]\frac{-3}{4}[/tex](x-8)
4( y+7) = -3(x-8)
4y +28 = -3x +24
3x +4y +28 -24 =0
3x +4y +4=0

What is the coefficient of the second term in the expression 2n+7m+6
Answer:
the answer is seven.
Step-by-step explanation:
The coefficient of the second term will be equal to 7.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
A coefficient in mathematics is a multiplicative factor in some term of a polynomial, series, or expression.
Given that the expression is 2n+7m+6. Here the first term is 2n second term is 7m and the third term is 6. The coefficient of the second term will be 7.
