Answer:
<h2>
y=6.25x+8.5</h2>
Step-by-step explanation:
Step one:
Given data
amount of money earned per hour= $6.25
amount of money made in tips= $8.5
if x represents the number of hours worked and
y represents the total amount earned
The linear function for the total is expressed as
y=mx+c
Step two:
Hence for the situation given the expression for the total is
y=6.25x+8.5
Say Kayla worked for 2 hours
that is x=2, the total she would have earned is
y=6.25(2)+8.5
y=12.5+8.5
y=21
For a 2 hour work, Kayla will make $21
3.19,3.51,3.72,3.93
Step-by-step explanation:
3.19=3.2
3.51=3.5
3.72=3.7
3.93=3.9
you take over the number kn the tenth .... if its 1 234 you round down and if its 5 or more you round up... simple
Y=(1/2)x^2 + 2x - 1
3x - y = 1, or y=3x-1
substitute
3x-1=(1/2)x^2+2x-1
0=(1/2)x^2-x
0=x(0.5x-1)
x=0,2
y=2+4-1=5
3(2)-1=5.
When x=2 y=5 (2,5) is one solution
when x=0, y=-1, (0,-1) is the other solution
Answer:
(3, 1)
Step-by-step explanation:
Answer:
.
n = -3.
Step-by-step explanation:
Since both sides have the same base (23), we can solve for n.
n + 8 = 5
n = 5 - 8
n = -3.
Hope this helps!
