Step-by-step explanation:
The slope m of the line = tan45° = 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 1 , then
y = x + c
To find c substitute (2, 1 ) into the equation
1 = 2 + c ⇒ c = 1 - 2 = - 1
y = x - 1 ← equation of line
When x = 0 then y = 0 - 1 = - 1
The line passes through (0, - 1 )
Answer:
72/27
Step-by-step explanation:
Because all you have to do is multiply by any number to the numerator and denominator same number I used 9 for some reason but since you multiplied them both by the same number the new fraction will be equivalent
Radius = diameter/2 = 8/2 = 4m
Area of a circle = pi x r^2 = pi x 4^2 = 16pi m^2 ( exact area) or 50.27 m^2
Circumference = pi x diameter = 8pi m ( exact) or 25.12 m
7+3 = 10 total marbles
1st pick = 7/10 for a red one
2nd pick = 6/9 reduces to 2/3 for a red one
3rd pick = 3/8 for a white one
7/10 x 2/3 =14/30 reduces to 7/15
7/15 x 3/8 = 21/120 reduces to 7/40
probability = 7/40
X - 10 = 25
add 10 to both sides
X = 35
