Answer:
y = -4x + 8
Step-by-step explanation:
The equation of a line is written in slope-intercept form : y = mx+b
m is the slope
We are given two points, so let's find the slope of the line first:
Slope = ΔY/ΔX = 4 - (-4) / 1 - 3 = 8 / -2 = -4
The slope is -4
So far, our equation is y = -4x + b
We can input a point's x and y value to find b, the y-intercept
Let's use point (1, 4)
4 = -4(1) + b
4 = -4 + b
b = 4 + 4
b = 8
The equation is y = -4x + 8

what is the range i need help
Answer:
[-7, 0]
Step-by-step explanation:
The range describes all values that y can take on. You may notica that the highest point of the graph has an y coordinate of 0 while the lowest has one of -7. Both values are included because they have filled in dots: this means the parenthesis are closed. So, the range would be: [-7, 0]. An alternate way to write this is [tex]-7\leq y \leq 0[/tex].
What is the solution to?
7x – 2y = 18
—4x + 3y = –14
• (-2, 2)
• (1, 6)
• (4, 5)
• (2, - 2)
Answer:
(2, -2)
Step-by-step explanation:
Solve 7x - 2y = 18 for x:
[tex]7x - 2y = 18[/tex] [tex]7x - 2y + 2y = 18 + 2y[/tex] (Add 2y to both sides)[tex]7x = 2y + 18[/tex] [tex]\frac{7x}{7} = \frac{2y+18}{7}[/tex] (Divide both sides by 7)[tex]x = \frac{2}{7}y+\frac{18}{7}[/tex]Substitute 2/7y+ 18/7 for x in -4x + 3y = -14
[tex]-4x + 3y = -14[/tex] [tex]-4(\frac{2}{7}y+\frac{18}{7})+3y=-14[/tex] [tex]\frac{13}{7}y-\frac{72}{7}=-14[/tex] (Simplify both sides of the equation) [tex]\frac{13}{7}y-\frac{72}{7}+\frac{72}{7} =-14+ \frac{72}{7}[/tex] (Add 72/7 to both sides)[tex]\frac{13}{7}y=\frac{-26}{7}[/tex] [tex]\frac{13}{7}y*\frac{7}{13}=\frac{-26}{7} * \frac{7}{13}[/tex] [tex]y = -2[/tex]Substitute -2 for y in x = 2/7y + 18/7
[tex]x = \frac{2}{7}y + \frac{18}{7}[/tex] [tex]x = \frac{2}{7}(-2) + \frac{18}{7}[/tex] [tex]x = 2[/tex] (Simplify both sides of the equation)Given that x = 2 and y = -2, the point is: (2, -2)
Therefore, the solution is (2, -2).

Step-by-step explanation:
We have been given an equation t=\frac{1}{500}dt=

d , where d represents distance traveled in miles and t represents time in hours.
To find the time taken by the flight to travel 800 miles, we will substitute d=800d=800 in our given equation as:
t=\frac{1}{500}\times 800t=
500

×800
t=\frac{800}{500}t=

800
t=\frac{8}{5}t=

t=1.6t=1.6
1 hour equals 60 minutes.
0.6 hours = 0.6*60 minutes = 36 minutes.
Therefore, it will take the plane 1.6 hours or 1 hour 36 minutes to travel 800 miles.

105 is 125% of what number
Answer: 84
We have, 125% × x = 105
or, 125100 × x = 105
Multiplying both sides by 100 and dividing both sides by 125,
we have x = 105 × 100125
x = 84
If you are using a calculator, simply enter 105×100÷125, which will give you the answer.
Answer:
84
Step-by-step explanation:
105÷126×100=84

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
The given expression is
csc² (x) - 2csc(x) cot(x) + cot² (x) = tan² (x/2)
Proceed LHS
csc² (x) - 2csc(x) cot(x) + cot² (x)
⇒ (1/sin²(x) ) - 2(1/sin(x) )(cos(x)/sin(x)) + (cos(x)/sin(x))²
⇒ (1 - 2cos(x) + cos(x)²)/sin(x)²
⇒ (1 - 2cos(x) + cos(x)²)/sin(x)²
⇒ (1 - cos(x))²/sin(x)²
⇒ (1 - cos(x))²/sin(x)²+
⇒ [(1 - cos(x))/sin(x)]² [ since tan(x/2) =(1 - cos(x))/sin(x)]
⇒ [ tan(x/2) ]²
⇒ tan²(x/2) = RHS
Hence proved.
