Determine if the lines are parallel, perpendicular or neither. Show all work.

x - 5y = 30 and 10y = 2x + 90

Answers

Answer 1

Answer:

The lines are parallel

Step-by-step explanation:

Determine If The Lines Are Parallel, Perpendicular Or Neither. Show All Work.x - 5y = 30 And 10y = 2x
Answer 2

Answer:

Step-by-step explanation:

Put the equations into slope-intercept form.

x-5y = 30 ⇒ y = ⅕x - 6

10y = 2x + 90 ⇒ y = ⅕x + 9

Both lines have slope = ⅕, so the lines are parallel.

Given: - 4x/7 > 10. Choose the solution set. {x | x < - } {x | x > - } {x | x > - } {x | x < - }

Answers

Answer:

{x | x < - 35 / 2}

Step-by-step explanation:

-4x / 7 > 10

Multiply both sides by 7

-4x /7 * 7 > 10 * 7

-4x > 70

Divide both sides by - 4

-4x / - 4 > 70 / - 4

x < - 35 / 2 (inequality sign changes)

A pole that is 2.5 m tall casts a shadow that is 1.34 m long. At the same time, a nearby building casts a shadow that is 46.5 m long. How tall is the building? Round to the nearest meter

Answers

Answer:

86.8 m long

Step-by-step explanation:

A pole that is 2.5 m tall casts a shadow that is 1.34 m long. At the same time, a nearby building casts a shadow that is 46.5 m long. How tall is the building? Round to the nearest meter

We solve the above question using the Proportion formula:

Height of the pole/Shadow of the pole = Height of the building /Shadow of the building

Height of the pole = 2.5m

Shadow of the pole = 1.34 m

Height of the building = x

Shadow of the building = 46.5m

Hence:

2.5m/1.34m = x/46.5m

Cross Multiply

1.34m × x = 2.5m × 46.5m

x = 2.5m × 46.5m/1.34m

x = 86.753731343m

Approximately , The height of the building = 86.8 m

Answer:

-3

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. So, in this equation, the b or y-intercept value is missing. The y-intercept is where the line crosses the y-axis. In this case, the line crosses over at the value of -3. Therefore, the missing value is -3.

they all equal 90

10.) No. Parallel lines do not cross each other, but these, if extended, would cross. You could use a protractor by measuring corresponding angles, and if they aren't equal, they aren't parallel.
