Answer:
ΔABC ~ ΔEFD
Step-by-step explanation:
ΔABC ~ ΔEFDc
Part A) First, you need to find out how much she makes each hour.40/5 = 8 & 48/6 = 8 ... This shows that she makes $8 an hour
To find the first missing number, you will do 8 * 8 = 64 ... This shows that she makes $64 in 8 hours.
To find the second missing number, you will do 56/8 = 7 ... This shows that she makes $56 in 7 hours.
Part B) Barb makes $9 every hour. To find the amount of money she earns for 5, 6, and 8 hours of work you will need to multiply $9 by the amount of hours she worked.
9 * 5 = 45 ... This shows that she makes $45 in 5 hours.
9 * 6 = 54 ... This shows that she makes $54 in 6 hours.
9 * 8 = 72 ... This shows that she makes $72 in 8 hours.
Part C) In part B, you found out how much she makes after working at the theme park for 5 hours. ($45 in 5 hours)
Next, you'll need to find out how much she makes after mowing lawns for 5 hours.
5*8 = $40 ... This shows that she makes $40 in 8 hours
Now you need to the difference. 45 - 40 = 5 ... She makes 5 more dollars working at the theme park for 5 hours than mowing lawns for 5 hours.
Answer:
D
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
If m > 0 , then line slopes upwards from left to right
If m < 0 , then line slopes downwards from left to right
y = 3x - 2
has m > 0 and c = - 2 , thus line slopes upwards crossing the y- axis at - 2
y = - 2x + 3
has m < 0 and c = 3, thus line slopes downwards crossing the y- axis at 3
on the graph this is the lower blue line and the red line
the solution to the system is at the point of intersection of the 2 lines
This is at point D
