Answer:
The equivalent expression for 
is 
Step-by-step explanation:
The distance in feet that Karina swims in a race is represented by 4d - 4, where is d is the distance for each lap.
To get equivalent expression we factor the expression 4d-4
Greatest common factor is 4
Factor out 4 from the expression 4d-4
when we factor out 4, we divide each term by 4
The equivalent expression for is
To find the x-intercept, plug zero into y and solve for x.
2x+3(0)=-18
2x=-18
/2 /2
x=-9
To solve for the y-intercept, do the same thing, but instead plug zero into the x-intercept to solve for y.
2(0)+3y=-18
3y=-18
/3 /3
y=-6
So, your answer to your question is the y-intercept=-6, and the x-intercept=-9

Answer:
21°
Step-by-step explanation:
the angles of triangle abc has to = 180 so subtract the known angles to get 21
angles bca and daf have to be the same so its 21
The answer to this is
x=8
