Solve the following system of equations. What is the y value of the solution?
Svet_ta [14]

Answer:

y = 2

Step-by-step explanation:

x + 5y - 10 = 0

X = 4y - 8

since x is given as = 4y - 8 we can use this in first equation

replace x with 4y - 8

x + 5y - 10 = 0 ➡ 4y - 8 + 5y - 10 = 0 add like terms

9y - 18 = 0 add 18 to both sides of the equation

9y = 18 divide both sides by 9

y = 2

subtract 11x to 9x

2x=0

divide Both sides by 2

x=0

A 25 - foot ladder is leaned against a wall. If the base of the ladder is 7 ft from the wall,
Fiesta28 [93]

Answer:

24

Step-by-step explanation:

Since the ladder, wall, and ground form a right triangle, you can use this formula:

A squared + B squared = C squared

A = 7 feet

C = 25 feet

B = distance the ladder will reach

49 + B squared = 625

B squared = 625 - 49

B = square root of 576

B = 24 feet
