Answer:
1200
Step-by-step explanation:
30 * 40 = 1200
the actual total cost would be 1326 because 39 * 34 = 1326
Answer:
y = 10 + 5x
Step-by-step explanation:
The question seem incomplete as the question requirement is not stated.
However, I'll solve for the equation and also plot the graph that illustrates the equation.
From the question, we have the following.
Base Amount = 10
Additional = 5 (weekly)
Let y represents her savings at any given weeks and x represents the number of weeks
y is calculated using
y = Base Amount + Additional * weeks
y = 10 + 5 * x
y = 10 + 5x
Next, it to plot the graph.
Take x = 0
y = 10 + 5 * 0
y = 10 + 0
y = 10
Take x = 3
y = 10 + 5 * 3
y = 10 + 15
y = 25
So, the graph must pass through
(0,10) and (3,25)
See attachment for graph.
The GCF of 20 and 70 is 10
90=10(7+2) could be used as another related expression
Answer:
yes it's rotated 180 degree angle
The slope is 3 and a point is (0,3)
