The x is a placeholder for a number. Think of x like a box and inside the box will go a number. In this case, -4 will replace x
7 - 2x = 7 - 2(-4) = 7 + 8 = 15
<h3>Answer: 15</h3>
Answer:
302.34L
Step-by-step explanation:
15 Apple barrels have the volume of 15*7056=105840Ci and
15 Cranberry barrels have volume of 15*5826=87390Ci.
ΔV = V(Apple barrels)-V(CranBerry Barrels) = 105840-87390 = 18450Ci.
Converting that to Litters gives ΔV 302.34L
The discrepancy in shipment volume is302.34L less than what the customer should have gotten.
Hi there!
Looking at the graph, the first intersection point is clear. The red parabola and blue line clearing intersect at the point (0, -1).
Find the second intersection point by setting the equations of both graphs equal to each other.
Line: y = 3x - 1
Parabola: y = 4x² - 1
Find another intersection point by setting these two equations equal to each other:
4x² - 1 = 3x - 1
Bring all terms onto one side:
4x² - 3x = 0
Factor out x:
x(4x - 3) = 0
Set 4x - 3 to 0 and solve:
4x - 3 = 0
4x = 3
x = 3/4
Plug in this value of x into an equation to solve for the y-coordinate. Use the linear equation for ease:
y = 3(3/4) - 1
y = 9/4 - 1
y = 5/4
(3/4, 5/4)
