(1) Today, the temperature in New York is -1 degree and is expected to rise 3 degrees per day. It's 6
degrees in Alaska and expected to fall 1 degree every 2 days.
Answers
Answer:
New York: m=3, b=-1, y=3x-1
Alaska: m=-1/2, b=6, y=-1/2x+6
2 days; 5 degrees
Step-by-step explanation:
In each case, m is the rate of change, the number of degrees per day that the temperature is changing. 1 degree per 2 days is 1/2 degree per day.
In each case, b is the given initial temperature.
The equation is y = mx + b, for the values of m and b that you fill in.
New York
m = 3, b = -1, equation: y = 3x -1
Alaska
m = -1/2, b = 6, equation: y = -1/2x +6
__
The graphs can be plotted by plotting the initial point on the y-axis, then finding another point based on the slope.
For New York, another point will be 1 unit right and 3 units up, at (1, 2).
For Alaska, another point will be 2 units right a 1 unit down, at (2, 5).
The lines intersect at the point (2, 5) corresponding to 2 days, 5 degrees.

Okay, so the answer for the imput of -2 is 0, so that means that the solution set is going to be (-2, 0). The answer for the imput of 0 is 1, so the solution set is going to be (0, 1). The answer for the imput of 2 is going to be 2, so the solution set is going to be (2, 2). The answer for the imput of 4 is going to be 3, so the solution set is going to be (4, 3). And lastly, the answer for the imput of 6 is going to be 4, so the solution set is going to be (6, 4).

When 20 is subtracted from five times a number, the result is the same as when 18 is added to three times the number. What is the number?
Answers
Answer:
Number is 19
Step-by-step explanation:
denote the number by x.
the line says:
5x - 20 = 18 + 3 x
Subtracting 3x form both sides
2x - 20 = 18
adding 20 to both sides
2x = 38
dividing both sides by 2
x = 19
Answer:
19
Step-by-step explanation:
let n = the number
5n - 20 = 18 + 3n
combine like terms in one of four different ways
2n = 38
n = 19

Answer:180
The answer you get divided by 20.
180/20=9.
Answer:
B
Step-by-step explanation:
Given y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when x = 20, y = 12, then
12 = 20k ( divide both sides by 20 )
k = [tex]\frac{12}{20}[/tex] = [tex]\frac{3}{5}[/tex]
y = [tex]\frac{3}{5}[/tex] x ← equation of variation
When x = 15, then
y = [tex]\frac{3}{5}[/tex] × 15 = 9

PLEASE HELP ME 20 POINTS!! Which lines are perpendicular to
6x + 18y = 5? Select all that apply.
Answers
Answer:
y=3x-10
y + 6 = 3(x − 15)
The multiplication of the slope of two perpendicular lines is -1 thus lines y=3x-10 and y + 6 = 3(x − 15) will be perpendicular to 6x + 18y = 5 therefore,option (A) and (C) will be correct.
What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
As per the given line,
6x + 18y = 5
18y = 5 - 6x
y = (-6/18)x + 5/18
y = (-1/3)x + 5/18
The standard form of line in slope(m) y-intercept form is y = mx + c .
The slope of above line m = -1/3
Since the multiplication of the slope of two perpendicular lines is -1.
Therefore, m × (-1/3) = -1
m = 3.
In line y=3x-10 the slope is 3 so it will be perpendicular.
In line y + 6 = 3(x − 15) ⇒ y = 3x - 21 slope is also 3 so it will also perpendicular.
Hence "The lines y=3x-10 and y + 6 = 3(x − 15) will be perpendicular to 6x + 18y = 5".
