(1, 3) and (-3, -5)
write a linear equation given the two points
Answer:
y = 2x + 1
Step-by-step explanation:
1. Find the slope; (change in y values)/(change in x values)
Slope = (-5 - 3)/ (-3 - 1) = -8/-4 = 2
2. Find the y-intercept (b) using the slope intercept formula: y = mx + b
m = 2 and using point (1, 3) , solve for "b"
y = mx + b
3 = 2(1) + b
3 = 2 + b
1 = b
3. Write the linear equation: y = 2x + 1
Use substitution to solve this system of an equation of y= 2x -4
A system of equations consists of at least two equations
The value of x is [tex]\mathbf{x = \frac{y}2 +2}[/tex]
The equation is given as:
y = 2x - 4
The actual question is to solve for x.
So, we start by adding 4 to both sides of the equation
y +4 = 2x - 4 + 4
y +4 = 2x
Rewrite the equation as:
2x= y +4
Divide both sides of the equation by 2
[tex]\mathbf{\frac{2x}2 = \frac{y +4}2}[/tex]
Divide 2x by 2
[tex]\mathbf{x = \frac{y +4}2}[/tex]
Split the fraction
[tex]\mathbf{x = \frac{y}2 +\frac{4}2}[/tex]
Simplify
[tex]\mathbf{x = \frac{y}2 +2}[/tex]
Hence, the value of x is [tex]\mathbf{x = \frac{y}2 +2}[/tex]

Which graph represents y=⌈x⌉over the domain 2≤x≤5 ?
Answer:
4
Step-by-step explanation:
#1 has to be excluded, since it jumps from 4 to 5 and has a hole between x=4 and x=5
#2 loses the extreme values. It would be correct if the domain was [tex]2<x<5[/tex]
#3 is including values in the interval [tex]1<x \leq 2[/tex] which aren't in our domain.

An electrician charges $45 for a house call and then an additional $16 dollars an hour to fix your lights. If the electrician is there for 4 hours, how much would you owe the electrician. You would owe them dollars
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
According to above statement ~
[tex]y = 16x + 45[/tex]where,
y = total money charged by electricianx = number of additional hour he/she worksso, let's plug the value of x as 4 hours to find y ( total money charged by the electrician )
that is ~
[tex]y = (16 \times 4) + 45[/tex][tex]y = 64 + 45[/tex][tex]y = \$ \: 109[/tex]So, you owe a total of $ 109 to the electrician ~

For Incap T-shirts, the cost of producing x t-shirts can be expressed as C=0.6x2+0.52x+3200.
The revenue they gain can be expressed as R=100x. What is the maximum profit (revenue subtract cost) they can make? In other words, what is the maximum value of R−C? Express your answer to 2 significant figures.
The maximum profit is $923.44 which is gotten when 83 T shirts are produced.
Given the function:
Profit = Revenue - Cost
Profit (P) = 100x - (0.6x²+0.52x+3200)
P = -0.6x² + 99.48x - 3200
The maximum profit is at dP/dx = 0, hence:
dP/dx = -1.2x + 99.48
0 = -1.2x + 99.48
1.2x = 99.48
x = 82.9
x ≅ 83
The maximum profit is at x = 83, hence:
P = -0.6(83)² + 99.48(83) - 3200
P = 923.44

What is the slope and y-intercept -4x+2y=-2
Answer:
Slope: 2
Y-intercept: (0, -1) or - 1
Step-by-step explanation:
Given the linear equation, -4x + 2y = -2:
Transform the given equation into its slope-intercept form, y = mx + b:
-4x + 2y = -2
Add 4x to both sides:
-4x + 4x + 2y = 4x - 2
2y = 4x - 2
Divide both sides by 2 to isolate y:
[tex]\frac{2y}{2} = \frac{4x - 2}{2}[/tex]
y = 2x - 1 ⇒ This is the slope-intercept form where the slope, m = 2, and the y-intercept is (0, -1).
