Answer:
y = 
x + 7
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 )
here m = , hence
y = x + c ← is the partial equation
to find c substitute (4, 9) into the partial equation
9 = 2 + c ⇒ c = 9 - 2 = 7
y = x + 7 ← equation in slope-intercept form
Answer:
x = -4
Step-by-step explanation:
3x + 5 = x - 3
Subtract x from each side
3x+5-x = x-3-x
2x+5 = -3
Subtract 5 from each side
2x+5-5 = -3-5
2x = -8
Divide each side by 2
2x/2 = -8/2
x = -4
For the last 2 questions,
1. 9/10
2. 7/12
Its math just use a calculator or something
What you do is you find the common denominator between the two fractions given. the easiest is to just multiply them
6*8=48
and then multiply each numerator by the number it's denominator is multiplied by
1*8=8 and 5*6=30
and now you have your new fractions, add them together
8/48+30/48=38/48
this leaves 10/48 as the people who were wearing shorts, just simplify this and it's done
10/2 =5/24
48/2
