Someone help with this
timama [110]

Answer:

18% decrease

Step-by-step explanation:

  1. 7,500 - 6,125 = $1,375
  2. Set up a proportion: \frac{1375}{7500} = \frac{x}{100}  
  3. Cross multiply, then divide: 1375 × 100 = 137500, 137500 ÷ 7500 = 18 1/3
  4. 18 1/3% rounded = 18%
  5. It went down, so it is a decrease

I hope this helps!

A straight line y = mx + c is parallel to y = 3x +2
Anna11 [10]

Answer:

m = 3 and c = - 1

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 )

y = 3x + 2 ← is in slope- intercept form

with m = 3

• Parallel lines have equal slopes, thus

y = 3x + c ← is the partial equation of the parallel line

To find c substitute (1, 2) into the partial equation

2 = 3 + c ⇒ c = 2 - 3 = - 1

y = 3x - 1 ← equation of parallel line

with m = 3 and c = - 1
