Answer:
Luke = 12 games
Naliba = 6 games
Step-by-step explanation:
Luke and naliba are playing squash
Luke wins twice as many games as naliba
They play a total of 18 games
Luke= 2x
naliba = x
2x +x= 18
3x= 18
x= 18/3
x= 6
Luke= 2(6)
= 12
naliba= 6
Hence luke wins 12 games and naliba wins 6 games
All of your x-values are positive, so f(x) = x². The statements that are true are
f(3) = 9
f(2) = 4
Let the selling price be S. The selling price based on selling price is found from:
Cross-multiplying, we get:
0.75S = S - 150
which when solved for S gives a selling price = $600.
To find the selling price based on cost, the following equation applies:
Cross-multiplying, we get:
112.50 = S -150
which when solved for S gives a selling price = $262.50.
Option B: isosceles
Option D: right
Solution:
Given data:
Three sides of the triangle are 5 cm, 7.1 cm and 5 cm.
If any two sides of a triangle are equal in length, then the triangle is called
an isosceles triangle.
Here, one side = 5 cm and the another side = 5 cm
Therefore the given triangle is isosceles.
If any one of the angle is 90°, then the triangle is right angled triangle.
Here "L" symbol represents the angle is 90°.
Therefore the given triangle is right angled triangle.
Option B and Option D are correct answer.
Hence the triangle is isosceles and right triangle.
