Answer:
$9.20
Step-by-step explanation:
the tax would be $0.80 because 8% of $10 is $0.80
so the total cost is $10.80
now subtract that by her $20 bill
20-10.80= 9.20
so she will be given $9.20 back in change
hope this helps luv <3
Answer:
m = 1
, y = 1x + 10
Step-by-step explanation:
The equation of a line is y = mx + c where m is the slope and c is the y-intercept. I will be calculating the slope using the points (7, 2) and (0, 10)
m = 
= 
= 
= 1
Based on the graph, the y-intercept is 10. Thus, the equation of the line is 1x + 10.
Answer:
g(1) = 1
Step-by-step explanation:
In this situation, one is given a graph of the function (g(x)), and one is asked to evaluate the function (g(x)) for (1). An easy way to do so is to find (x = 1) on the coordinate plane, then draw a vertical line at this point. Note the place where (x = 1) intersects the graph of (g(x)). The (y-coordinate) of this intersection point is the output of the function (g(x)).
The line (x = 1) intersects the function (g(x)) at the point (1, 1). Thus (g(1) = 1).
Answer: y = 23x - 62
<u>Step-by-step explanation:</u>
Parallel lines have the same slope.
y = 23x + 4
m=23 b=4
Input x = 3, y = 7, & m = 23 into the Point-Slope formula to find the equation or the Slope-Intercept formula to find b (you already have m). I will choose the latter.
y = mx + b
7 = 23(3) + b
7 = 69 + b
-62 = b
m = 23, b = -62 --> y = 23x - 62
Answer:
-3,-1
