Hi there,
The solution for x is 5/7 or 0.71428. I hope it works :-)
Answer:
B
Step-by-step explanation:
Find the slope to solve. The slope is rise/run. This means that the distance of going up and to the right from one point to the other. If the line has it so that, the point leads you down or to the left, the slope will be negative.
Starting at the point on the y-axis, moving up up 3 places and to the right 4 places gives you the slope 3/4.
The equation will be y = 3/4x + 1
Answer:
B. 6,-6
Step-by-step explanation:
X^2 + 12 = 48
Subtract 12 from each side
X^2 + 12-12 = 48-12
X^2 = 36
Take the square root of each side
sqrt(X^2 ) = sqrt(36)
X = ±6
It would be the last one for many reasons
Answer: the number of hotdogs that were sold is 35
the number of orders of fries is 52
Step-by-step explanation:
Let x represent the number of hotdogs that were sold.
Let y represent the number of orders of fries.
You sold a total of 87 hotdogs and orders of fried combined. This means that
x + y = 87
Each hot dog costs 1.50 and each order of fries costs 0.50. At the end of the night you made a whopping $78.50! This means that
1.5x + 0.5y = 78.5 - - - - - - - - - - -1
Substituting x = 87 - y into equation 1, it becomes
1.5(87 - y) + 0.5y = 78.5
130.5 - 1.5y + 0.5y = 78.5
- 1.5y + 0.5y = 78.5 - 130.5
- y = - 52
y = 52
Substituting y = 52 into x = 87 - y, it becomes
x = 87 - 52
x = 35
