ANSWER
The linear equation is: y = 80x + 65
Te cost for 40 football jerseys: $3265
EXPLANATION
Let 'x' be the number of jerseys and 'y' the cost of x jerseys.
Each jersey costs $80, so the cost of x jerseys is 80x. There's also an extra fee for procesing of $65, which is the same no matter how many jerseys they buy.
Therefore, the cost 'y' of x jerseys is:
Now we want to know the cost of 40 football jerseys, so we just have to replace x by 40 and solve:
Answer:
x=66°
Step-by-step explanation:
48+x+x=180
2x=180-48
2x=132
x=132/2=66
Answer:
$8
Step-by-step explanation:
320 x 20% = 64
64 x (1/8) = 8
I hope this helped!
The answer to question #1 is x = 7
For a line to be parallel to x = 8, it has to start with x = some number. Such a line would have an undefined slope.
Now, x = y is a line that goes through the origin. It has a slope of 1.
The answer to question #2 is y = 7
If a line is perpendicular to x = some number, then it has to be y = some number.
And this perpendicular line has to go through the point (4,7). So what is the y-value of this point, since the equation starts with y? The y-value is 7. So the equation has to be y = 7
