Answer:
equation: y=-5/9(x)+8/9 slope: y=-5/9(x)
Step-by-step explanation:
9y=8-5x
y=(8/9)-(5/9)x
y=-5/9(x)+8/9
Someone help and please make sure the answer is right
Answer:
This is the exterior angle theorem, so
x+30+x+22=130
2x+52=130
2x=78
x=39
sooooooooooooo
39+22=61 degrees
61 degrees
Answer:
21
Step-by-step explanation:
First set up the equation
130 + x + 30 + x + 22 = 180 (triangle angles always add up to 180)
then start to solve to find x
130 +2x + 30 + 22 = 180
182 + 2x = 180
-182 -182
2x = -2
/2 /2
x = -1
Then just plug it back into the equation
-1 + 22

Given that R=7x+5Y find Y when X=9 and R=35 give your answer as an improper fraction in its simplest form
Please help
Answer:
y = -28/5
Step-by-step explanation:
R = 7x +5y
35 = 7(9) + 5y
35 = 63 +5y
-5y= 63- 35
-5y/-5 = 28/-5
Y = -28/5
Answer:
Y = - [tex]\frac{28}{5}[/tex]
Step-by-step explanation:
Given
R = 7X + 5Y ← substitute X = 9, R = 35
35 = 7(9) + 5Y
35 = 63 + 5Y ( subtract 63 from both sides )
- 28 = 5Y ( divide both sides by 5 )
- [tex]\frac{28}{5}[/tex] = Y
simplify as far as possible:3x+4y+7y
Answer:
3x+4y+7y = 3x + 11 y
Step-by-step explanation:
We need to simplify the given expression i.e.
3x+4y+7y
We know that, the like terms gets add up i.e. the sum of 4y and 7y equals 11 y
So,
3x+4y+7y = 3x + 11 y
Hence, the final simplification should be 3x + 11 y.
Solve the system:
x+4y=1
3x+5y=10
Answer:
[tex]x=6.25\\y=-1.25[/tex]

Second equation times 3:
[tex]3x+9y=3[/tex]
1st equation minus equation above:
[tex]-4y=7\\y=-7/4[/tex]
Insert to equation:
[tex]3x+\frac{-35}{4}=10\\12x-35=40\\12x=75\\x=75/12=6.25[/tex]
What is the resulting equation when the expression for y in the second equation is substituted into the first equation-3x+2y=-3
Y=4x+1
Answer:
x=-5/11, y=-9/11. (-5/11, -9/11).
Step-by-step explanation:
3x+2y=-3
y=4x+1
---------------
3x+2(4x+1)=-3
3x+8x+2=-3
11x=-3-2
11x=-5
x=-5/11
y=4(-5/11)+1
y=-20/11+11/11
y=-9/11
Y+3= -5(x-1) write the equation in slope intercept form
Answer: The equation in slope-intercept form: [tex]y=-5x+2[/tex]
Step-by-step explanation:
The given equation of a line : [tex]y+3= -5(x-1)[/tex]
The equation of a line in slope -intercept form: y=mx+c, where m= slope , c=y-intercept.
We first use distributive property(a(b+c)=ab+ac) to simplify the given equation, we get
[tex]y+3=-5x+5[/tex]
Subtract 3 from both sides, we get
[tex]y=-5x-2[/tex]
Hence, the equation in slope-intercept form: [tex]y=-5x+2[/tex]

Emily runs a hotel. She wants to hold a party in the banquet hall of her hotel. The hall has a size of 120,000 square feet. By fire code the maximum population density of the hall is 0.004 people per square foot. This includes all the people in the banquet hall. What is the maximum number of people that can attend the party if she has it in the banquet hall?

Calculate the value
of the unknown
coefficient b of a
quadratic equation
when the
discriminant of that
equation is known.
3x² + bx + 2 = 0; Coefficient = 12
Answer:
The value of b is either + 6 or -6
Step-by-step explanation:
Here, given that we have the value for the discriminant, we want to calculate the value for the coefficient of x
mathematically, the discriminant can be calculated using the equation;
D = b^2 - 4ac
a represents the coefficient of x^2 which is 3
b represents the coefficient of x given as b
2 represents the last number
D is the discriminant = 12
So we have that;
12 = b^2 - 4(3)(2)
12 = b^2 - 24
b^2 = 24 + 12
b^2 = 36
b = √36
b = +6 or -6

SOMEONE HELP ME PLEASE 30 POINTS
Answer:
D. (+,-)
Step-by-step explanation:
Map it out!
Quadrant I's points will always be (+,+). It is located in the upper right section.
Quadrant II's points will always be (-,+). It is located in the upper left section.
Quadrant III's points will always be (-,-). It is located in the lower left section.
Quadrant IV's points will always be (+,-). It is located in the lower right section.
The x-coordinate and y-coordinate are both negative, which is the right statement. The best choice is B.
When determining the location of points or other geometrical elements on a manifold, such as Euclidean space, a coordinate system in geometry uses one or more numbers or coordinates.
The value of the coordinate x and the value of the coordinate y are both negative in the fourth quadrant's coordinate system.
As a result, it is true to say that both the x- and y-coordinates are negative. The correct response is B.
