Answer:
(1,-3)
Step-by-step explanation:
(1,-3) is the only point which satisfies the equation.
When x = 1, y = -3
-3 = 2(1) - 5
-3 = 2 - 5
-3 = -3 ( a true statement)
Answer:
x = - 5
Step-by-step explanation:
= 2x ( multiply both sides by 3 to clear the fraction )
2x - 20 = 6x ( subtract 2x from both sides )
- 20 = 4x ( divide both sides by 4 )
- 5 = x
"When the sides are congruent (same direction and size), and the two opposite sides are parallel, the angles are the same. In an isosceles triangle, two angles are congruent, because two sides are congruent."

Answer:
Volume of solid is
Step-by-step explanation:
We need to find the volume of solid formed by rotating the region bounded by the graph of , y-axis and the line y=3 about the line y=5.
Please see the attachment for figure.
Using Shell method,
where,
a=0 (Lower limit of solid)
b=4 (Upper limit of solid)
(Outer Radius of Shell)
r=2 (Inner radius of shell)
dx is thickness of shell
Volume of shell, dV=Area of shell x Thickness
Volume of solid
Thus, Volume of solid is

Complete Question:
A sundae requires 2 ice-cream scoops and 4 raspberries, and a milkshake requires 3 ice-cream scoops and 5 raspberries. Laila wants to sell sundaes and milkshakes with at most 80 ice-cream scoops and 150 raspberries. Let S denote the number of sundaes she makes and M the number of milkshakes she makes. Write an inequality that represents the condition based on the number of (ICE-CREAM SCOOPS).
Answer:
An inequality that represents the condition based on the number of (ICE-CREAM SCOOPS) is given as:
2S + 3M ≤ 80
Step-by-step explanation:
From the above question, we are told that:
Let S denote the number of sundaes Laila makes
M the number of milkshakes
a) A sundae requires 2 ice-cream scoops and 4 raspberries
A sundae = 2S and 4S
b) A milkshake requires 3 ice-cream scoops and 5 raspberries.
A milk shake = 3M and 5M
Laila wants to sell sundaes and milkshakes with at most 80 ice-cream scoops and 150 raspberries .
Therefore, an inequality that represents the condition based on the number of (ICE-CREAM SCOOPS) is given as:
2 ice cream scoops + 3 ice cream scoops ≤ 80
2S + 3M ≤ 80
