The lengths of the sides of a triangle are 7. and 10. If the length of the longest side of a similar triangle is 25. what is the length of the shortest side of this triangle?

Answers

Answer 1
Answer:

Answer: 17.5

Step-by-step explanation:

7:10 = x:25

times both sides by 25

25(7/10) =x

than solve for x

X = 25 × (7/10)

X = 17.5

A line contains the point (-2, 2) and is parallel to the line y = ½x + 8. What is the equation of this parallel line?

Answers

Answer:

y = (1)/(2) x + 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given the line with equation

y = (1)/(2) x + 8 ← in slope- intercept form

with slope m = (1)/(2)

• Parallel lines have equal slopes , then

y = (1)/(2) x + c ← is the partial equation of the parallel line

to find c, substitute the point (- 2, 2 ) into the partial equation

2 = (1)/(2) (- 2) + c = - 1 + c ( add 1 to both sides )

3 = c

y = (1)/(2) x + 3 ← equation of parallel line
