Answer:
y= -4x+-3 = y=-4x-3
The rest are wrong.
Hi there! :)
We are given the slope of the line and its y-intercept.
So, we write the equation in slope-intercept form (y=mx+b)
m is the slope of the line, and b is the y-intercept.
y=mx+b
y=-4x-3
Hence, that's the equation (Option A)
Hope it helps. Use the comment section to clarify your doubts.

(50 points) Suppose the light pattern from a fog light can be modeled by the equation x^2/25 - y^2/9=1. One of the points on the graph of this equation is at (6, 3 sqrt 11/5), and one of the x-intercepts is -5. Which coordinate is not a point on the graph?
Answer:
Both points are on the graphStep-by-step explanation:
Given function
x^2/25 - y^2/9 = 1To find
Check if given points are on the graph (6, 3 sqrt 11/5) and (-5, 0)Solution
Verifying the points are on the line by substituting values of x and y:
1.............................
6^2/25 - (3√11/5)²/9 = 136/25 - 11/25 = 125/25 = 11 = 1Correct2.............................

The time taken by the shipping company to pack 180 boxes is 15 hours.
What are the ratio and proportion?The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
The given graph is the direct relation and has a constant proportion as,
Book packed/hour = 60/5 = 12
With this constant of proportionality,
For 180 boxes,
180/hour = 12
Hour = 15
Hence "It takes the shipping business 15 hours to pack 180 cartons".

Missing data shown below,
in the given figure ab parallel cd find the value of x
Step-by-step explanation: x = 73°
Draw PQ through E and parallel to AB, CD
Have x = ∠QED + ∠QEB
because PQ // CD => ∠QED = 50°
AB // PQ => ∠QEB + 157° = 180°
=> ∠QEB = 180 - 157 = 23°
=> x = 23° + 50° = 73°
( PQ is in the same direction as AB and CD )
angle efd = 130
180-50=130
angle ahe =23
180-157= 23
draw a imaginary line from h to f
this will create a triangle
now angle hfc = 90
90-50=40
now angle hfe =
90 - 23 = 67
therefore ,
x =
67+40+x=180
107 + x = 180
x = 180-107
x=73

For the function F defined by F(x)=x2−2x+4, find F(−2).
Answer:
F(-2) = 12
Step-by-step explanation:
F(-2) = (-2)²- 2(-2) + 4
= 4 - (-4) + 4
= 4 + 4 + 4
= 12
The required value of function F(x) = x² − 2x + 4 at F( -2 ) is 12.
A quadratic function is given F(x) = x² − 2x + 4, value of the function is to be determined at x = -2.
What is a polynomial function?
A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
F(x) = x² − 2x + 4
Above given function is a quadratic function,
in order to find F(-2) , we have to put x = -2 in above given function.
F( -2 ) = ( -2 )² − 2( -2 ) + 4
F( -2 ) = 4 + 4 + 4
F( -2 ) = 16
Thus, the required value of function F(x) = x² − 2x + 4 at F( -2 ) is 12.

What is the value of x?
Answer:
x = 7
Step-by-step explanation:
all triangles add up to 180
(90 from the right angle)
90 + (4x) + (5x +27) = 180
117 + 9x = 180
-117 - 117
9x = 63
x = 63/9
x = 7
Answer:
x = 7
Step-by-step explanation:
All triangles add up to 180, and (90 from the right angle)
90 + (4x) + (5x +27) = 180
117 + 9x = 180
-117 - 117
9x = 63
x = 63/9
Therefore, x = 7

Tommy bought a total of 30 apples and oranges for a classic picnic. Apple's cost $3 per pound and oranges cost $4 per pound. Tommy spent $100 total. How many apples and oranges did Tommy buy?
Answer:
20 apples and 10 orangesStep-by-step explanation:
Let amount of apples be x and oranges be y
Then we have:
x + y = 303x + 4y = 100Subtract triple of the first equation from the second one:
3x + 4y - 3(x + y) = 100 - 3*303x - 3x + 4y - 3y - 10y = 10Then finding x
x = 30 - 10 = 20So apples = 20, Oranges = 10

The measure of angle O from the given triangle is 9°.
Given that, m∠N=(5x-8)°, m∠O=(x-5)° and m∠P=(6x+1)°.
We need to find the measure of angle O.
What is the angle sum property of a triangle?Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
Now, m∠N+m∠O+m∠P=180°
⇒ (5x-8)°+(x-5)°+(6x+1)°=180°
⇒ 5x+x+6x-8-5+1=180
⇒ 12x-12=180
⇒ 12x=192
⇒ x=192/12
⇒ x=16
So, m∠O = 16-5=9
Therefore, the measure of angle O from the given triangle is 9°.

PLEASE HELP FOR GEOMETRY
9514 1404 393
Answer:
m∠DCE = 58°
m∠CDE = 74°
m∠DAE = 119°
Step-by-step explanation:
The incenter is the point of intersection of the angle bisectors. The angles on either side of the bisector have the same measure. Of course, the sum of angles in a triangle is 180°.
m∠DCE = 2×29° = 58°
m∠CDE = 180° -58° -2×24° = 74°
m∠DAE = 180° -74°/2 -24° = 119°
