Answer:
earnings = $125 + ($50/vacuum)x
Step-by-step explanation:
This problem is best described by a linear equation whose slope is $50/vacuum and whose y-intercept is $125:
The equation represents the man's total earnings. The independent variable is x, the number of vacuums he sells.
Thus, earnings = $125 + ($50/vacuum)x. As before, the y-intercept is $125 and the slope of the line is ($50/vacuum).
Plot a black dot at (0, $125). Now move 2 units to the right from this dot and from there up by $100 to (2, $225). Plot this new point. Then draw a line through the two points you've plotted.
Table:
x earnings
---- --------------
0 $125
1 $125 + $50 = $175
2 $125 + $100 = $225
and so on.

Lynn put 3 7/8 gallons of gas in her gas tank. If there are now 18 1/6 gallons in the tank, how many gallons did she start with?
x - gallons she started with
Answer:
14.3 gallons = 4 + 7.25/25 or 14.29 gallons.
Explanation:
18 1/6 gallons - 3 7/8 = 14.29
18 - 3 = 15
1/6 - 7/8 = 15 - 0.70833333333 = 14.2916666667
You need to be careful here if you use basic subtraction, simply as two minus would change to addition.

Shape I is similar to shape ll.
*then it’s the picture which is listed below*
The sequence that proves shape l is similar to shape ll when applied to shape l is a reflection across the *x-axis or y-axis* followed by a translation *4, 5, 6, or 7* units right and *2, 3, 4, or 5* units down, and then a dilation by a scale factor of *0.5, 1, 1.5, or 2*.

What is the y-intercept of a line that has a slope of -3 and passes through point (-5, 4)? a) -17 b) -11 c) 7 d) 19
Answer:
(- 11)
Answer b is correct
Step-by-step explanation:
To find this you can use
y = mx + c
Here,
m = slope
c = y - intercept
( -5, 4) = ( x ,y)
Let us solve now .
[tex]y = mx + c[/tex]
[tex]4 = - 3 \times - 5 + c \\ 4 = 15 + c \\ 4 - 15 = c \\ - 11 = c[/tex]
Therefore,
c = (-11)
That means y - intercept is ( -11 )
Hope this helps you.
Let me know if you have any other questions :-):-)
Answer: b (-11) , hope it will help

Solve for x.
4 (x + 1 1/3) = 9 2/3
Enter your answer as a mixed number in simplest form.
Answer:
x = 13/12
x = 1 1/12
Step-by-step:
4 (x + 1 1/3) = 9 2/3
4x + 5 1/3 = 9 2/3
subtract 5 1/3 from each side
4x = 4 1/3
divided by 4 on each side
x = 13/12
x = 1 1/2
At the end of the season, Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% disount. What is the sale price of the bat?

347.25-121.54$225.7The sale price of the bat will be;
⇒ $225.71
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% disount.
Now,
Since, Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% discount.
Hence, The discount price = 35% of $347.25
= 35/100 × $347.25
= $121.54
Thus, The sale price = $347.25 - $121.54
= $225.71
