Step-by-step explanation:
Alex gets paid for $6.00 PER hour
In June:
Alex worked for 11 hours.
In July:
19 hours.
You can do 19*6.00 (Lets just do 19*6 for now to make it easier)
19*6=114
Change it to $144.00
In June:
You can do 11*$6.00. '(Lets just do 11*6 for now to make it easier)
11*6=66.
Change it to $66.00
Add the money Alex earned.
June + July= $66+144=$180

(7, -1) 2. What is the slope of a line that is perpendicular to the line joining point A (9, 9)? and point B
Answer:
-1/5Step-by-step explanation:
Given the point A (9, 9) and B(7, -1)
The slope of the line AB is expressed as:
slope = Δy/Δx
slope = y2-y1/x2-x1
slope = -1-9/7-9
slope = -10/-2
slope = 5
For two lines to be perpendicular, the product of their slope must be -1
mM = -1
M is the slope of the line perpendicular to AB
Substitute m = 5 into the equation
5M = -1
M = -1/5
Hence the slope of a line that is perpendicular to the line joining point A and B is -1/5

With the summer approaching, Mya decides to start a small lawn mowing business in her town. The initial cost for the lawnmower and other fixed expenses is $450. She determines it will cost her $6 per lawn for gasoline and maintenance. Mya decides to charge customers $20 per lawn.
Step-by-step explanation:
I believe we are expected to solve for the number of lawns she would mow before she could make profit
let the cost be C
and let the price be P
and let the number of lawn be x
C=$450----------1
P=6+20x---------2
equating 1 and 2 we can find x
450=6+20x
450-6=20x
444=20x
x=444/20
x=22.2
therefore for her to break even and start making profit she need to mow 22.2 lawns and above
Solve the following system of equations:
2x + 4y = 18
-3x + 2 = y
A.(-1, 4)
B.(1, 4)
C.(-1, 5)
D.(1, -1)
Answer:
Option C
Step-by-step explanation:
Given the following question:
[tex]2x+4y=18[/tex]
[tex]-3x+2=y[/tex]
To find the answer we need to find the values of each of the variables by solving one equation at a time, and then substitute those answers into each equation in till we have our answers.
[tex]2x+4y=18[/tex]
[tex]-3x+2=y[/tex]
[tex]y-y=0[/tex]
[tex]-3x+2+ -y=0[/tex]
[tex]2-2=0[/tex]
[tex]-3x+-y=0+-2[/tex]
[tex]-3x+3x=0[/tex]
[tex]-y=3x-2[/tex]
[tex]-y\div-1=y[/tex]
[tex]3x+2\div-1=-3x+2[/tex]
[tex]y=-3x+2[/tex]
Substitute y for -3x + 2:
[tex]2x+4y=18[/tex]
[tex]y=-3x+2[/tex]
[tex]2x+4(-3x+2)=18[/tex]
[tex]2x+4(-3x+2)=18=-10x+8=18[/tex]
[tex]-10x+8=18[/tex]
[tex]8-8=0[/tex]
[tex]18-8=10[/tex]
[tex]-10x=10[/tex]
[tex]-10x\div10=x[/tex]
[tex]10\div-10=-1[/tex]
[tex]x=-1[/tex]
Substitute x for -1:
[tex]y=-3x+2[/tex]
[tex]x=-1[/tex]
[tex]y=-3(-1)+2[/tex]
[tex]-3\times-1=3[/tex]
[tex]y=3+2[/tex]
[tex]3+2=5[/tex]

In 1992 the average family income was about 42000, and in 2002 it was about 56256. Let x = 0 represent 1992, x = 1 represent 1993, and so on. Find values for a and b (rounded to one decimal place if necessary) so that f ( x ) = a x + b models the data a = b = What was the average family income in 1997? $
Step-by-step explanation:
Given the function that models the income of a family as g(X) = ax+b
at x = 0, g(x) = 42000, the function becomes;
g(X) = ax+b
42000 = a(0)+b
42000 = 0+b
b = 42000
at x = 1, g(x) = 56256
56256 = a(1) + b
56256 = a+b
a = 56256 -b
a = 56256 - 42000
a = 14,256
To get the average family income in 1997, wee need to calculate g(x) at when x = 5, since the number of years between 1992 and 1997 is 5years.
g(x) = ax+b
g(5) = 14256(5) + 42000
g(5) = 71,280+42000
g(5) = 113,280
Hence the average family income in 1997 is 113,280

Answer:
12$
Step-by-step explanation:
he worked from 1:45-4:45 wich means he worked 3 hours,then 3 hours *4$ =12$
Answer:
12 dollars
Step-by-step explanation:
Hello!
To solve this question, we understand that:
- the rate at which he earns money is 4 dollars an hour.
-if we find how many hours elapsed between 1:45pm-4:45pm, it is three hours which means he has worked for three hours
(4:45pm-1:45pm=3:00 hours)
Knowing this equation, we must figure out how much he earns during this time frame, 3 hours.
Since we know that the rate is 4 dollars an hour and he has worked 3 hours, let's multiply 4 times 3 (or add 4 three times 4+4+4) to get 12 dollars he has worked during this time.

The solution of the considered system of equation is represented by: Option C: (1,3) and (4,0)
What is a solution to a system of equations?For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs, so solution to a system is the intersection of all its equation at single point(as we need common point, which is going to be intersection of course)(this can be one or many, or sometimes none)
For the considered case, the system of equations given to us is:
[tex]y = x^2 - 6x + 8\\y = -x + 4[/tex]
Plotting both's graph and finding the common points on both's graph, we get the common points as:
(1,3) and (4,0)
These points satisfy both the equations simultaneously.
