Answer:
-35
Step-by-step explanation:
Not in Option, actually because x=-11
if y=3(-11)-2
then y = -33-2
y = -35
Answer:
Draw a dashed line to represent the graph of , and shade the portion above the line for positive values of x and y
Step-by-step explanation:
Let
x------> the number of nickels in the box
y------->the number of dimes in the box
we know that
so
Multiply by both sides
-----> inequality that represent the situation
The solution of the inequality is the shaded area above the dashed line for positive values of x and y
The equation of the dashed line is
therefore
the answer is
Draw a dashed line to represent the graph of , and shade the portion above the line for positive values of x and y
see the attached figure to better understand the problem
One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).
Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.
The unit rate is 2,86:2,50
Cancel out -4/3 by adding 4/3
Then add 4/3 to 7 giving you 7 4/3
divide 7 4/3 by 5 giving you 1 2/3 or 5/3
X = 4 y = 3 4x-3y=7 x=13-3y
4(13-3y) -3y =7
52 -12y -3y =7
-15y=-45
-y=-3 y = 3
x=13-(3*3)
x=13-9
x =4
