The equations 13x + 15y = 55.50 and 46x + 16y = 131.50 can be utilized to find out the cost per pound for both bananas and grapes, where x represents the price for bananas and y denotes the price for grapes.
This question is quite lengthy, so I will offer a brief overview. To find your x-value, set y to 0 in the given equation.
2x + 3y = 1470
2x + 3(0) = 1470
2x = 1470
x = 735
Thus, your farthest point on the x-axis is (735,0).
Now, repeat for y.
2x + 3y = 1470.
2(0) + 3y = 1470
3y= 1470
y= 490
Your highest point thus is (0,490).
After plotting both points, connect them with a straight line to illustrate your graph.

Sample Answer: To determine the difference between 10 and 13, you apply the concept of additive inverses. Juan is lacking $3 to buy his supplies.
Response:
9.55 minutes
Step-by-step breakdown:
x hours to reach the river
0.25-x hours for the return trip, as 15 minutes equals 0.25 hr.
to the river 40 mph * x hours =40x miles
from the river 70 mph (0.25-x) hours=17.5-70x
these two equations are equivalent
40x=17.5-70x
110x=17.5
x=17.5/110=0.159 hours
9.55 minutes
Response:
The function is represented by the equation,
x = 3y.
Detailed explanation:
The direct variation function includes the points (-9, -3) and (-12, -4).
Here,
= 3
Thus, the function can be expressed as,
x = 3y.
