Answer:
Slope = 1/2
y-intercept = 30
Equation : y = 1/2x + 30
D. 150 miles
Step-by-step explanation:
We can use the two visible points you marked on the graph.
They are (0,30) which is also the y-intercept and (20,40).
Calculate change of y over change of x.
10/20 or 1/2
So the slope is 1/2 and the y-intercept is 30.
Therefore, using y = mx + b form, the equation is y = 1/2x + 30
Then, to find how many miles you drove if the cost was $105, we can plug in 105 for y in the equation.
105 = 1/2x + 30
75 = 1/2x
x = 150
Coordinates of the vertices of JKL
J = (-5,-2)
K = (-3, -6)
L = (-1, -6)
Translation two units left => new x-coordinate = original x-coordinate - 2 and y-coordinate does not change.
J' = (-7,-2)
k' = (-5,-6)
L' = (-3,-6)
Jeni gets paid $ 303.75 for 3 days
<em><u>Solution:</u></em>
Given that,
Jeni works from 8:00-3:15 three days in a row
<em><u>Find the number of hours between 8 : 00 to 3 : 15</u></em>
8 : 00 to 3 : 15 = 7 hours 15 minutes
She is taking half-hour unpaid lunch break each day
7 hours 15 minutes - half an hour = 6 hours 45 minutes
So, she works for 6 hours 45 minutes for each three days
She is paid $15 per hour
<em><u>Therefore, total earnings for 3 days is given as:</u></em>
Thus she gets paid $ 303.75 for 3 days
Using the intersecting chord theorem:
a x b = c x d
x+21 * 4 = x+3 * 10
Simplify:
4x+84 = 10x+30
Subtract 30 from both sides:
4x + 54 = 10x
Subtract 4x from both sides:
54 = 6x
Divide both sides by 6:
x = 9
