Answer:
y=3x+5
Step-by-step explanation:
Since the equation will be parallel, the slope will still be 3.
y=3x+b
Enter the point (1,8) into the equation.
8=3(1)+b
8=3+b
b=5
y=3x+5
Answer C : 3x^2+7xy-2y^2
equivalent to the following expression
Combine like terms
2x^2 + x^2 is 3x^2
4xy+3xy is 7xy
-y^2-y^2 is -2y^2
So expression becomes
Answer C is correct
40/1 is the same 80/2 120/3 160/4
Probability is desired outcome divided by total outcomes.
There is only 1 four and 1 five on a die. Thus, there are 2 outcomes she wants.
There are 6 sides.
2/6 = 1/3 or 0.33 probability.
Y= mx +b
the first line:
sustitute:
4=m(-2)+b
remplace intercept in y:
4=-2m-6
-2m=(4+6)/-2
m=-5
The first equation is y=-5x-6
For the perpendicular the slope is 1/5
so
y-y1=m(x-x1) use the second coordenates
y+4= 1/5(x-5)
y=(1/5)x-1-4
y=(1/5)x-5 That's the answer: Letter C
