The correct solution method of Kendall's money is 7x = 98. Divide both sides by 7. Kendall had $14
<h3> How to write equation?</h3>
x = Kendall's money
Mateo's money = $98
= 7 × x
The equation:
7 × x = 98
7x = 98
x = 98/7
x = $14
Therefore, the correct answer is option B

★ ∆ ABC is similar to ∆DEF
★ Area of triangle ABC = 64cm²
★ Area of triangle DEF = 121cm²
★ Side EF = 15.4 cm
★ Side BC
Since, ∆ ABC is similar to ∆DEF
[ Whenever two traingles are similar, the ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides. ]
❍ <u>Putting the</u><u> values</u>, [Given by the question]
• Area of triangle ABC = 64cm²
• Area of triangle DEF = 121cm²
• Side EF = 15.4 cm
❍ <u>By solving we get,</u>
<u>Hence, BC = 11.2 cm.</u>

Answer:
f^-1 (x) = 1/2x -5/2
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y = 2x+5
Exchange x and y
x = 2y+5
Solve for y
Subtract 5 from each
x-5 = 2y+5-5
x-5 = 2y
Divide by 2
(x-5)/2 = 2y/2
1/2x - 5/2 = y
f^-1 (x) = 1/2x -5/2
