Answer:
1. y = 4x - 4
2. y = x + 2
3. y = -2x - 4
4. y = -x + 2
Step-by-step explanation:
Slope-intercept form is y = mx+b. As we know, m is the slope and b is the y-intercept. We need to find the slope and y-intercept and put them in the equation. Slope is rise over run, so we just count up then over until we get to an intersection. For the y-intercept, we look where the line crosses the y-axis.
Answer: it can be any equation that would equal 100
Step-by-step explanation:
First two rolls have to be 1-4 that is 2/3 chance twice and the third can be 4or 5
2/3*2/3*1/3 + the chance that the fourth is the 5 or 6.
2/3*2/3*2/3*1/3
So the solution is : P=2/3*2/3*1/3 + 2/3*2/3*2/3*1/3
Sqrt(x) - 5+7 =11
combine like terms
-5 +7 = 2
sqrt(x) + 2 = 11
subtract 2 from each side
sqrt(x) = 9
square both sides
x = 9^2
x = 81
an extraneous solution would be an invalid solution
in this case it is not an extraneous solution
a) n° + n°+ 42 = 180°
2n + 42 = 180
2n = 180 – 42
2n = 138
n = 138 /2
n° = 69°
_____o___o____
b) ( x+10) + x + ( x+5 ) = 180
x + 10 + x + x + 5 =180
3x + 15 =180
3x =180 – 15
3x = 165
x = 165 /3
x° = 55°
_____o___o___
c) 3q + q + q = 180
5q =180
q = 180/5
q=36°
___o___o____
d) m + 2m + ( m+10) = 180
m+2m+m+10=180
4m + 10=180
4m = 180 – 10
4m = 170
m=170 / 4
m = 42.5°
____o___o___
e) y + (y – 30 ) + 90° = 180°
y + y – 30 + 90 = 180
2y + 60 = 180
2y = 180 – 60
2y = 120
y = 120/2
y = 60°
____o___o____
f) ( t + 10.5 ) + 2t + 90 = 180
t + 10.5 + 2t +90=180
3t + 100.5 = 180
3t = 180 – 100.5
3t = 79.5
t = 79.5/3
t =26.5°
I hope I helped you^_^
